Description

  The present invention relates to a communication server that constitutes a communication system together with a communication terminal, and a communication method when a user cannot respond when an incoming call is received.

  Conventionally, when a call is heard from a mobile communication terminal such as a mobile phone but the ringing tone flows but the called party does not answer, that is, when the incoming caller cannot answer the call, the call is connected to the forwarding or answering machine service. If the function is not provided, the telephone is called several times and, for example, a message indicating that the telephone cannot be answered is sent, and then the telephone is automatically disconnected.

By listening to this message, the caller can guess that the callee is currently unable to answer the call. However, the caller does not know when to call back.
In order to avoid this, for example, a callable time zone is registered in the exchange in advance, and for calls made outside this time zone, the exchange notifies the callable time by a voice message (for example, Patent Document 1), or a method of automatically sending a document including the latest schedule data within a predetermined time from the incoming date and time to the sender side by mail (for example, see Patent Document 2) is proposed. ing.

However, as described above, in the method of notifying the caller of the callable time and schedule information of the user on the called side, for example, a call operation is performed from one of the plurality of callers to one called terminal. In some cases, the caller is notified of the callable time and schedule information.
Therefore, when the same time is notified to a plurality of callers as the callable time, when each caller performs a call operation again on the receiving terminal at the notified callable time, There is a possibility that the user of the receiving terminal is talking to one caller and the other callers cannot talk to the user of the receiving terminal again.

In particular, depending on the caller, it may be necessary to promptly contact the receiving terminal and the user of the calling terminal, but this is inconvenient when the notified callable time is several hours ahead. It is.
Furthermore, the caller who has not been able to talk to the user of the receiving terminal needs to perform a call operation on the receiving terminal again at the notified callable time. In some cases, it is necessary to take measures such as the user of the receiving terminal re-calling the caller.
Therefore, the present invention has been made paying attention to the above-mentioned conventional unsolved problems, such as when the user of the receiving terminal cannot respond when a call request is made by the caller. Another object of the present invention is to provide a communication server and a communication method capable of more reliably realizing a call between a caller who cannot make a call and a user of a receiving terminal.

Based on the schedule information corresponding to the user of the called terminal, the called side within a predetermined time from when the called side non-response detecting unit detects that the called terminal is not responding. A response time search unit (for example, corresponding to the response time search unit 53b in the schedule search unit 53 of FIG. 6) that searches a time period in which the user of the terminal can make a voice call as a response time, and the response time search unit The response available time adjustment unit for assigning the response available time retrieved in step (2) to a non-response originating side terminal that cannot obtain a response from the incoming side terminal (for example, the schedule in FIG. 6). Corresponding to the response time adjustment unit 53c in the mail search unit 53) and the response time allocated to the non-response originator terminal by the response time adjustment unit acquired by the notification destination address acquisition unit A response available time transmission unit (e.g., corresponding to the response available time transmission unit 53d in the schedule search unit 53 in FIG. 6) for transmitting to the notification destination address corresponding to the user of the non-response transmission side terminal, and the response available time adjustment unit In the time zone corresponding to the response possible time allocated to the non-response originating side terminal, and making a call to the non-response origination terminal and the receiving side terminal allocated the response possible time, An automatic call control unit (for example, the automatic call control unit 56 in FIG. 6) that connects between the non-response call side terminal and the call receiving side terminal when both users of the non-response call side terminal and the call receiving side terminal respond. And the receiving terminal responds with a call request from another caller terminal during processing for a call made to the callee terminal with a call request from the caller terminal. The communication terminal is capable of executing processing for a call made to a called terminal, and the response time adjustment unit determines a priority order for a plurality of the non-response calling terminals, and the response time search unit retrieved response possible time, is characterized in split dipped Rukoto preferentially in order from the higher priority unanswered calling terminal.

By adopting such a configuration for the communication server, for example, a response possible time can be assigned to the non-response transmission side terminal in consideration of the priority order. In addition, it automatically calls the unanswered caller terminal and the callee terminal at the assigned response time, and connects between the unanswered caller terminal and the callee terminal. Accordingly, it is possible to save the trouble of the user of the non-response transmission side terminal and the reception side terminal.
In addition, since the communication server has such a configuration, the response time adjustment unit can preferentially allocate response time from a higher priority to a plurality of non-response transmission side terminals. Usability can be further improved.

A communication server according to an aspect of the present invention includes a priority information holding unit (for example, FIG. 6) that holds priority information indicating a priority set in advance by the user of the receiving terminal with respect to the user of the calling terminal. Corresponding to the priority information holding unit 51c in the database unit 51), and the response possible time adjusting unit is a non-response transmission side corresponding to a user whose priority is set among the non-response transmission side terminals When there is a terminal, it is characterized in that the higher the priority is assigned to the non-response transmission side terminal corresponding to the user for which the priority is set, the more recent response possible time is allocated.
With such a configuration of the communication server, it is possible to assign a response available time with a designated priority.

<Overall configuration>
FIG. 1 is a block diagram showing a configuration of an example of a mobile communication system 1 to which the present invention is applied.
As shown in FIG. 1, the mobile communication system 1 is connected to terminals (MS: Mobile Stations) 2A, 2B, and 2C, an MME (Mobility Management Entity) 3 connected to the terminals 2A and 2C, and a terminal 2B. Customer information management database (DB) realized by MME4, sound source server (MRF: Media Resource Function) 5, SMS / mail creation server (SMSC: Short Message Center) 6, and HLR (Home Location Register), for example The device 7 and a 3PCC (3rd party call control) server 8 are configured to provide communication services based on LTE (Long Term Evolution). , Constitute the LTE network system. LTE is a communication standard for a mobile communication system standardized by 3GPP (3rd Generation Partnership Project).

In the mobile communication system 1, the terminals 2A to 2C have the same functional configuration and include a display unit and an operation unit. Further, the terminals 2A to 2C have a function of a general LTE-compatible mobile phone, and can handle even when there are a plurality of incoming calls at the same time.
Here, “when there are a plurality of incoming calls simultaneously” is a case where a call request is made from a plurality of caller terminals. Even in this case, a server such as an MME associated with the call request Processing for a plurality of calls from the device on the side can be performed together. That is, the terminals 2A to 2C are requested to send a call when a call request is made from another caller terminal during a process for a call from a server-side device accompanying a call request from the caller terminal. Accordingly, it is possible to perform processing for a new call made from the server side device. In other words, at the receiving terminal, in response to a call request from a certain calling terminal, until the ringing signal is received and the ringing tone begins to sound or the ringing tone is sounding, Even when a call is made to the call, processing for this call can be performed.

Each of the terminals 2A to 2C has a function of displaying caller information related to the caller at the time of an incoming call and a function of performing line connection with a terminal selected as a reception target.
The MMEs 3 and 4 have the same functional configuration. The MMEs 3 and 4 are nodes constituting an LTE network, and transfer user data between the terminals 2A to 2C through a communication network (not shown) and the customer information management database device 7. FIG. 1 shows a case where the terminals 2A and 2C operate as a caller terminal, and a terminal 2B operates as a callee terminal. The terminal 2B on the receiving side operates as the receiving side MME in which the terminal 2B is located.

In addition, when there is no response at the receiving terminal in response to a call request from the calling terminal, the MMEs 3 and 4 are called users of the receiving terminal (hereinafter also referred to as callees) as necessary. Is sent to the caller terminal by SMS or e-mail.
The sound source server 5 determines whether or not there is a plurality of incoming calls at a specific terminal based on the caller number (phone number) of the caller terminal and the callee terminal. When receiving a connection response indicating that connection is not possible from the receiving terminal, the guidance information specified by the connection disabling parameter notified from the receiving terminal is transmitted to the designated calling terminal.

Further, the sound source server 5 transmits ring back tone (RBT) information to the caller terminal in response to a request from the MMEs 3 and 4.
The SMS / mail creation server 6 has a mail creation function using general SMS or e-mail, and generates a response time notification message addressed to the caller terminals 2A and 2C in response to a request from the MME 3 or MME 4.

This response time message is a message for notifying a user of a terminal on the calling side (hereinafter also referred to as a caller) of a response time indicating a time zone in which the callee can respond to a voice call. .
Further, the SMS / mail creating server 6 stores the user of the terminal on the sending side of the mail and the user of the terminal on the receiving side of the mail exchanged between the terminals and the current communication time in association with each other.

  The customer information management database device 7 includes a scheduler that manages schedule information for each user of each terminal connected via a communication network, including the terminals 2A to 2C, and stores the phone book information for each user of each terminal. to manage. Furthermore, the customer information management database device 7 associates and stores the call time of the voice call made between the terminals and the users of the two terminals that have made the voice call as a voice call history.

In addition, a time zone in which the user of the receiving terminal can respond is notified as a response available time to the calling terminal that the user of the receiving terminal could not respond to the call request from the calling terminal. .
The 3PCC server 8 uses SIP (Session Initiation Protocol), and at the timing designated by the customer information management database device 7, attempts to establish a line connection between the terminal as the calling side and the terminal as the receiving side.

<Functional configuration of terminal>
Next, the functional configuration of the terminals 2A to 2C will be described.
FIG. 2 is a block diagram illustrating an example of a functional configuration of the terminals 2A to 2C.
As shown in FIG. 2, the terminals 2 </ b> A to 2 </ b> C include a scheduler operation unit 11, a telephone directory operation unit 12, a priority order setting unit 13, a caller information display unit 14, a call processing unit 15, and guidance item display. Unit 16 and guidance information notification unit 17. Note that the terminals 2A to 2C also have general functions as mobile communication terminals such as connection processing with counterpart terminals at the time of outgoing and incoming calls.

The scheduler operation unit 11 displays a scheduler operation screen for the user holding the terminals 2A to 2C to operate the scheduler on the display unit of each terminal, and the schedule data set on the scheduler operation screen is The data is transmitted to the customer information management database device 7 in association with it.
Further, the scheduler operation unit 11 acquires the corresponding schedule data from the customer information management database device 7 in accordance with the user's request operation at each terminal, and displays the screen on the requesting terminal.

  The phone book operation unit 12 displays a phone book screen for the user holding each terminal to operate the phone book on the display unit, and associates the phone book data set on the phone book screen with each terminal. To the customer information management database device 7. Further, the phone book operation unit 12 acquires phone book data corresponding to the user of the terminal from the customer information management database device 7 according to the user's request operation at each terminal, and displays the screen on the request source terminal.

Here, as the telephone directory data, not only the telephone number of the other party but also a notification destination address such as an e-mail address or an SMS address is set in association with the telephone number.
The priority order setting unit 13 sets the priority order for the terminal on the calling side when setting the response available time. The priority order information set by the priority order setting unit 13 is transmitted to the customer information management database device 7 and is stored in the customer information management database device 7 in association with each terminal. Further, the priority order setting unit 13 acquires priority order information corresponding to the terminal from the customer information management database device 7 in response to a user's request operation at each terminal, and displays the current setting status.

The caller information display unit 14 displays the caller information notified by the “call” received from the MME 3 or MME 4 on the display unit.
The caller information is information for identifying the user of the caller terminal that has made a call request to the callee terminal, for example, the name of the user. That is, when the caller information display unit 14 is in a situation where the callee terminal receives one or more “calls” transmitted from the MME in response to a call origination operation at the caller terminal, the caller information display unit 14 performs a process for this. Caller information about the caller terminal that made the call request is displayed.

  The call processing unit 15 selects one sender from the sender information corresponding to the terminal that requested the outgoing call displayed on the display unit of the own terminal by the sender information display unit 14. When the information is selected, the caller terminal specified by the caller information selected by the user is recognized as the reception target terminal. Then, the call processing unit 15 performs connection processing for connecting between the reception target terminal and the own terminal, and between the non-reception target terminal and the own terminal that are not selected as the reception target terminals. For the interval, a process at the time of disconnection is performed to disconnect these intervals.

When the caller information displayed on the caller information display unit 14 is selected as a reception target, the guidance item display unit 16 displays caller information that is not selected as a reception target, that is, non-reception target caller information. Guidance items set in advance in association with the position are displayed on the display unit of the terminal itself.
The guidance information notifying unit 17 transmits, as a connection impossible parameter, guidance selection information for specifying a guidance item selected by a user performing a selection operation on the receiving terminal among the guidance items displayed on the display unit of the terminal itself. To the local MME.

  The guidance item is an item for specifying a message to be notified from the incoming call terminal to the user of the outgoing call terminal set as the non-receiving target terminal. The guidance items include an answering machine guidance for notifying you that you will be connected to the answering machine service, a return guidance for notifying you that you will immediately call back, and a call back guidance for requesting you to call again. and so on.

The connection processing unit 21 performs connection processing between the terminal managed by the MME and the communication partner terminal via the customer information management database device 7.

In addition, the connection processing unit 21 performs a process at the time of connection for connecting between the terminals on the receiving side and the terminal on the receiving side, which will be described later, selected by the user as the target for receiving on the receiving side terminal, For the connection between the terminal and the receiving terminal, a non-connection process for disconnecting these terminals is performed.
The incoming side no-response detection unit 22 detects that the incoming side terminal is not responding to the outgoing request from the outgoing side terminal. Specifically, when a “connection response (timeout)” is received from the terminating circuit switch as a response to the “connection request” from the originating terminal transmitted by the originating circuit switch, It is determined that it is a response.

  When the incoming side non-response detecting unit 22 detects that the incoming side terminal is not responding, the telephone directory search instructing unit 23 transmits a “destination side telephone book confirmation request” to the customer information management database device 7, In addition to instructing whether or not the caller ID (that is, telephone number) of the caller terminal is registered in the telephone directory of the callee terminal, the scheduler search is instructed.

  The SMS / mail creation instructing unit 24 receives the caller ID of the calling terminal from the customer information management database device 7 according to the “calling destination phone book confirmation response”, and the called party's phone book is registered. Is sent to the SMS / mail creation server 6. The SMS / mail creation instructing section 24 transmits a “message creation request”, and transmits information specifying the sender terminal that is the destination of the mail and the response time to the SMS / mail creation server 6. Note that the information specifying the terminal on the calling side includes an e-mail address and an SMS address, which are the notification destination address of the terminal on the calling side, acquired from the telephone directory.

When the call execution unit 25 receives a “connection request” addressed to the same destination terminal from another terminal while making a call to the one terminal on the other side, A “call” corresponding to the “connection request” is transmitted to the same receiver terminal.
The call timer monitoring unit 26 activates a call timer when receiving a “connection request” from the originating MME and transmitting a “call” for making a “connection request” to the counterpart terminal. This call timer is a timer for determining that the user of the receiving terminal does not respond, and when the timer value reaches a predetermined value corresponding to a preset calling time, the user of the receiving terminal does not respond. Judge.

In addition, when the call timer monitoring unit 26 receives a “connection request” addressed to the same receiver side terminal from another terminal in a state where “call” is performed on the one receiver terminal, After resetting the calling timer, a “call” addressed to the receiving terminal is transmitted from another terminal to the receiving terminal.
Note that MME3 and MME4 cannot be connected when it is determined that the user of the partner terminal does not respond even if a predetermined calling time has elapsed based on the calling timer measured by the calling timer monitoring unit 26. The process of notifying is also performed.

As shown in FIG. 4, the sound source server 5 includes a calling / receiving terminal recognition unit 31, a guidance generation unit 32, a sound source 33, and a processing unit (CPU) 34.
The calling / receiving terminal recognizing unit 31 manages the calling party number (that is, the telephone number) and the destination telephone number of the connection request that are notified together with the “connection request” from the calling side MME. The caller ID of the calling terminal is different, but when there is a “connection request” that matches the telephone number of the other terminal of the connection request destination, there are multiple calls to the connection request destination terminal. Recognize

When the guidance generating unit 32 receives the RBT disconnection request and the connection impossible parameter from the originating MME, the guidance generating unit 32 transmits the guidance information specified by the connection impossible parameter together with the “RBT disconnection request” to the designated originating terminal. The sound source 33 is instructed.
The sound source 33 holds the guidance information corresponding to the guidance item in association with the connection impossible parameter. In addition, ringing tone information for generating a ringing tone at the originating terminal is held. Then, when the guidance generation unit 32 instructs to transmit guidance information specified by the connection impossible parameter, the corresponding guidance information is transmitted to the designated caller terminal.

Further, the sound source 33 recognizes that a plurality of calls are made to the same receiving terminal in the calling / receiving terminal recognizing unit 31, and when the “request to start RBT” is made from the calling MME The ringing tone information is transmitted to the designated caller terminal. Further, when the “starting response of RBT” is made from the calling side MME, the transmission of the ringing tone information addressed to the designated calling side terminal is stopped.
The processing unit 34 controls the calling / receiving terminal recognizing unit 31, the guidance generating unit 32, and the sound source 33.

FIG. 5 is a block diagram showing an example of the functional configuration of the SMS / mail creation server 6.
As shown in FIG. 5, the SMS / mail creation server 6 includes a response time acquisition unit 41, a notification message generation unit 42, a response time transmission unit 43, and a mail communication history collection unit 44. Yes.
The response available time acquisition unit 41 receives the “message creation request” from the MMEs 3 and 4 and acquires the information specifying the response available time and the caller terminal notified together with the “message creation request”. Further, the response possible time acquisition unit 41 receives a “message retransmission request” from the customer information management database device 7. Moreover, the information which identifies the terminal of the transmission side used as the transmission destination terminal of this response possible time notified with this "message re-transmission request" is acquired.

  The notification message creation unit 42 is used for notifying the sender of the response possible time of the receiver based on the response available time and the notification destination address acquired together with the “message creation request” by the response available time acquisition unit 41. Generate response time notification message. In this response time notification message, for example, a fixed sentence of a response time notification message for notifying that a call is made at the notified response time is prepared in advance, and the acquired response time is applied to the fixed sentence. Etc.

The response available time transmission unit 43 transmits the response available time notification message or the response available time re-notification message generated by the notification message creation unit 42 to the notification destination address of the response available time acquired by the response available time acquisition unit 41. To do.
The mail communication history collection unit 44 associates the history of SMS and e-mail communication between the terminals with the time when the message was exchanged and the user of the terminal on the transmitting side and the receiving side in advance. Store in the storage area.

<Functional configuration of customer information management database device>
FIG. 6 is a block diagram illustrating an example of a functional configuration of the customer information management database device 7.
As shown in FIG. 6, the customer information management database device 7 includes a database unit 51, a telephone directory search unit 52, a schedule search unit 53, a response time notification history collection unit 54, a call history collection unit 55, And an automatic transmission control unit 56.
The database unit 51 includes a schedule information holding unit 51a, a telephone directory information holding unit 51b, and a priority order information holding unit 51c.

The schedule information holding unit 51a holds the schedule information of the user holding each terminal in association with the user.
The phone book information holding unit 51b holds phone book information registered by a user who uses each terminal in association with the user.
The priority information holding unit 51c holds the priority information registered by the user who uses each terminal in association with the user.
The telephone directory search unit 52 includes a telephone directory registration state determination unit 52a and a notification destination address acquisition unit 52b.
When the phone book registration status determination unit 52a receives the “calling side phone book confirmation request” from the MMEs 3 and 4, the phone book registration state determination unit 52a refers to the caller's phone book, and stores the caller ID, that is, the caller's phone number in the caller's phone book. It is determined whether or not the number is registered.

When the phone book registration state determination unit 52a determines that the caller number is registered in the caller's phone book, the notification address acquisition unit 52b is associated with the caller number. An address or email address is acquired as a notification destination address.
The schedule search unit 53 includes a notification availability determination unit 53a, a response time search unit 53b, a response time adjustment unit 53c, a response time transmission unit 53d, and a response time transmission unit 53d.

When the telephone directory registration state determination section 52a determines that the caller's telephone number is registered in the telephone directory of the callee, the notification availability determination section 53a determines the response time of the user of the receiving terminal. It is determined that it is possible to notify the calling terminal.
When the notification availability determination unit 53a determines that the response available time can be notified, the response available time search unit 53b refers to the schedule information of the callee, and that the callee can make a voice call. The time that can be considered is searched as a response time. A method for searching for the response time will be described later.

The response possible time adjustment unit 53c includes a latest schedule determination unit c1, a favorite registration determination unit c2, and a match determination unit c3. Then, when there are a plurality of transmission side terminals that should be notified of the response time, the response time adjustment unit 53c determines the priority order of the transmission side terminals, and the response to be notified to each transmission side terminal according to the determined priority order Adjust the possible time. A method for adjusting the response available time will be described later.
As used herein, the “calling side terminal that should notify the available response time” refers to the calling side terminal in which the user of the receiving side terminal could not respond to a call accompanying a call request from the calling side terminal (Corresponding to the terminal without answering).

  In other words, when there is an incoming call accompanying a call request from another caller terminal during processing for a call from the MME accompanying a call request from a caller terminal, that is, when there are multiple calls simultaneously. The user of the receiving terminal can only respond to any one of the transmitting terminals. Alternatively, when the user of the receiving terminal cannot respond to the call at this time, it cannot respond to any calling terminal.

For this reason, in this embodiment, among the calling side terminals that have made a call request to the called side terminal, a time period in which the called side terminal can answer the call to the calling side terminal that the user of the called side terminal has failed to respond to Is notified as a response time.
In this way, because there are multiple incoming calls at the same time, or because the user of the receiving terminal is not in a situation where the user can answer the call, a call can be made between the user of the receiving terminal and the user of the calling terminal. The caller terminal that did not exist is referred to as a “caller terminal that should be notified of the available response time”.

For example, the response possible time adjustment unit 53c determines the priority order and sets the most recent response possible time zone as the response possible time in order from the highest priority order. In addition, in order from the highest priority, the available response time that is convenient for the caller terminal is preferentially set.
Note that the response possible time may be set as a response possible time in a different time zone for each calling terminal. In addition, when the response time period is longer than a preset reference time, that is, when the time period is relatively long, the user of the receiving terminal can respond to the users of the plurality of transmitting terminals. Therefore, the same time zone may be set as a response available time for a plurality of caller terminals.

  The response available time transmission unit 53d sends the response available time set by the response available time adjustment unit 53c to the originating terminal that should be notified of the response available time to the MME that is the transmission source of the “calling side phone book confirmation request”, and The “destination phone book confirmation response” is transmitted together with the notification destination address acquired by the notification destination address acquisition unit 52b to notify that the caller's telephone number is registered in the receiver's phone book. In addition, the retrieved response available time, the user of the receiving terminal and the user of the calling terminal are associated with each other and notified to the response available time notification history collection unit 54. Further, when the response time adjustment unit 53c has a plurality of transmission side terminals to which the response time is to be notified and priorities are set for these, for example, the plurality of transmission side terminals compare priorities with each other. The response time notification history collection unit 54 is also notified in association with the information indicating the same group and the priority order.

The response available time notification history collection unit 54 associates the response available time searched by the response available time search unit 53b with the receiving terminal and the calling terminal, and sets the response available time notification preset as the response available time notification history. Store in the history storage area.
The call history collection unit 55 stores, for each user, a call time when a voice call is made between terminals in a voice call history storage area set in advance as a voice call history in association with a user of a call destination terminal. To do.

The automatic transmission control unit 56 refers to the history data stored in the response time notification history collection unit 54 and extracts history data in which the latest time zone is set as the response time. Note that the history data includes a response time, a user at the calling terminal and a user at the receiving terminal, and also includes a priority when included in the same group.
Whether or not “the most recent time zone is set” is, for example, a response time in which the start time of the time zone specified by the response time is within a predetermined time set in advance from the current time. Sometimes, it is determined that “the most recent time zone is set”.

Then, in the history data in which the most recent time is set as the response possible time, the 3PCC server 8 is instructed to automatically connect between the caller terminal and the callee terminal in descending order of priority.
That is, the time zone notified as the response possible time is not set to the early time zone in order from the earliest timing when the receiving side terminal could not respond to the outgoing call request from the outgoing side terminal, For example, when the time zone in which both the receiving side terminal and the calling side terminal can respond is set as a response available time, the response available time zone may be set later than the current time zone. .

That is, there is a possibility that the time zone set as the response available time may be set as the response available time for a plurality of caller terminals.
Therefore, the priority order is determined for the history data in which the latest time zone is set as the response time, and the automatic connection is instructed to the 3PCC server 8 in order from the highest priority order.
The determination as to whether or not the priority is high may be made in the same manner as the response time adjustment method in the response time adjustment unit 53c. Alternatively, it may be determined that the longer the elapsed time from the time when the calling terminal makes a call request, the higher the priority.

  In addition, when the history data in which the same time zone is set as the response available time is only history data corresponding to the calling side terminal set as the same group, for the calling side terminals belonging to the same group The priority order that is set, that is, the priority order that is determined when setting the response time in the response time adjustment unit 53c may be used.

Further, the automatic call control unit 56 instructs the 3PCC server 8 to automatically connect between the caller terminal and the callee terminal based on the history data in which the latest time zone is set as the response time. If so, the connection result of the automatic connection is received from the 3PCC server 8. When the 3PCC server 8 notifies that the voice call between the caller terminal and the callee terminal is established as “connection established”, the history data of the voice call established is deleted from the response time notification history collection unit 54 To do.
The customer information management database device 7 also acquires position information of each terminal from an MME or the like that manages the terminal according to the location of each terminal, and manages position information of each terminal.

<How to search for response time>
Next, a method for searching for a response time in the response time search unit 53b of the schedule search unit 53 will be described.
FIG. 7 is an example of a scheduler operation screen displayed on the scheduler operation unit 11.
For example, as shown in FIG. 7, the scheduler is configured so that a daily schedule can be registered in units of 30 minutes, which can be registered for one week or one month. As the schedule items to be registered, for example, it is possible to set own work schedule, vacation, conference / meeting, meeting, etc. Furthermore, whether the conference / meeting / meeting is attendance information or hold. Such information can be registered.

The response time search unit 53b determines, for example, a time zone in which schedule data is not set as an idle time, and detects this as a response time.
For example, among the schedule items included in the set schedule data, a time zone in which a preset schedule item is set is determined as a response possible time or a non-response possible time.
For example, when the registered schedule item is “meeting”, “meeting”, or “meeting”, a telephone response cannot be made, but a telephone response can be made when working at his / her own seat.
Further, even when “conference”, “meeting”, and “meeting” are registered, if “absent” is indicated, a telephone response can be made.

In addition, in the case of “annual leave”, a telephone response cannot be made.
Therefore, whether or not a telephone response is possible is set in advance for a keyword predicted to be registered as schedule data. The keyword may be set so that the user can set it on the terminal side. Note that the response time search unit 53b may set in advance.
Further, the scheduler is configured to manage the time zone and the schedule data set in the time zone in association with each other.
Then, as shown in FIG. 8, the response possible time search unit 53b stores in advance keywords that cannot be answered by telephone, and the scheduler performs keyword search for the schedule data, and schedule data including the response impossible keywords is obtained. The set time zone is determined as a time zone during which telephone response is not possible.

When a response time search is requested, the response time search unit 53b searches for a response time in the above-described procedure for a time zone within a predetermined time after the time when the search request is made. .
The predetermined time is a time that defines how many hours later from the time when an incoming call is received to the caller side. The response time may be extracted from one or more time zones. For example, when the schedule is clogged, there are few response time zones, and there are only about 30 minutes even if there is a response time zone, it is possible to notify a plurality of time zones as response time. Good.

<How to adjust response time>
Next, a method for adjusting the response time in the response time adjustment unit 53c of the schedule search unit 53 will be described.
In the response time adjustment unit 53c, first, priority is set for any of the transmission side terminals to be notified of the response time as the priority level holding information corresponding to the receiving side terminal held in the priority level information holding unit 51c. If so, the determination is made according to this priority order. That is, the response time is allocated in order from the latest response time in descending order of priority.
For those for which priority is not set, the latest schedule determination unit c1 notifies the schedule information corresponding to the receiver terminal of the sender terminal and receiver that should notify the available time as a schedule within a predetermined period set in advance. It is determined whether or not there is a calling-side terminal registered with a schedule that needs to be promptly communicated with the terminal.

  Specifically, the schedule information held by the schedule information holding unit 51a includes whether the latest schedule with the user is included in the calling side terminal that should be notified of the available response time as schedule information corresponding to the called side terminal. judge. For example, schedule information includes time zone, schedule item (for example, meeting, meeting, meeting, meeting, etc.), location, who to meet, meeting, meeting, meeting attendee, etc. If it is configured to be able to set partner information such as a person who is scheduled to meet or contact, this partner information is referred to. Then, in the schedule items within a predetermined time set in advance from the present time, when the partner information includes information for identifying the user of the caller terminal to be notified of the response time, It is determined that the user needs to promptly contact the user of the originating terminal. Then, it is determined that the higher the priority is, the closer to the originating terminal corresponding to the most recent schedule item.

  For the calling side terminal that is not registered in the most recent schedule of the called side terminal, the favorite registration determining unit c2 refers to the phone book information corresponding to the user of the calling side terminal, and this phone book is a person who often makes calls. If the favorite partner can be registered, it is determined whether or not the user is registered as a favorite among the transmitting side terminals to be notified of the response available time. If it is registered as a favorite, it is determined that the priority of this user is high.

  Further, for the calling side terminal not registered in the favorites, the matching determination unit c3 matches the schedule information of the user of the calling side terminal with the schedule information of the user of the called side terminal, and there is a time zone in which both can respond. It is determined whether or not there is a blank, that is, a match or a partial match. And when the time zone in which both can respond is overlapped, this call-out side terminal determines that the priority is high. In this case, a time zone in which both searched users can respond is set as a response available time of the calling terminal.

For example, as shown in FIG. 9, the customer information management database device 7 holds the latest schedule information of each terminal.
Therefore, the response time of the user of the calling side terminal 2A and the response time of the user of the receiving side terminal 2B are searched, and the time when these response time overlaps is detected. In the case of FIG. 9, the time zones in which both can respond are 12: 0 to 12:30 and after 13:30.

Therefore, the latest 12: 00 to 12:30 is set as the response available time.
Among the transmission side terminals that should be notified of the response possible time, it is determined that the priority is higher as the timing at which the transmission operation from the transmission side terminal is performed is earlier. For example, in the customer information management database device 7, when a call destination in-zone inquiry is made from the calling MME, the time when the inquiry is made is set as the calling time, and the calling terminal and the receiving terminal are associated with each other. It is memorized as outgoing time information. Then, with reference to the transmission time information, the priority order may be set by comparing the transmission time for the transmission side terminal corresponding to the transmission side terminal to be notified of the response time.
Then, according to the priority order determined in this way, a response possible time is assigned to the calling terminal.
Here, as described above, a case has been described in which it is determined that the priority is higher in order from the one that satisfies the conditions in order, but for example, it is determined that the higher the priority is, the higher the priority is, among these conditions. You may make it do.

<Functional configuration of 3PCC server>
Next, the functional configuration of the 3PCC server will be described.
FIG. 10 is a block diagram illustrating an example of a functional configuration of the 3PCC server 8.
As shown in FIG. 10, the 3PCC server 8 includes an automatic connection control unit 61 and a control result notification unit 62.
The automatic connection control unit 61 has a function of making a call connection between designated terminals using a known 3PCC. Then, the automatic connection control unit 61 specifies the specified caller terminal at the specified response available time based on the response available time notified from the automatic call control unit 56 and the caller terminal and the callee terminal. When the user of the caller terminal and the user of the callee terminal both respond, the caller terminal and the callee terminal are connected and the terminals are connected. As a result, a voice call can be made between the user of the caller terminal and the user of the callee terminal.

  The control result notification unit 62 notifies the automatic transmission control unit 56 of the connection result indicating whether or not the connection is established by the automatic connection control unit 61. In other words, when the call request from the automatic connection control unit 61 is answered by both the user of the caller terminal and the callee terminal and a voice call is established between the user of the caller terminal and the callee terminal, the connection is established. Notify as. On the other hand, when at least one of the calling side terminal and the called side terminal does not respond to the call request from the automatic connection control unit 61 and the voice call between the users of the calling side terminal and the called side terminal is not established. Notifies that the connection is not established because the two cannot be connected.

<Screen display example of terminal>
Next, an example of a display screen at the time of outgoing call and incoming call on the outgoing side and incoming side terminals will be described.
FIG. 11 shows an example of the display screen of the terminal on the calling side and the receiving side, where (a) shows the case where there is one caller and (b) shows the case where there are two callers. It is.
As shown in FIG. 11 (a), when there is only one caller, when a call is made at the caller terminal, for example, 2A, a ringing tone is generated at the terminal 2A and a call is being made such as “calling”. Is displayed on the screen.

On the other hand, the terminal 2B on the receiving side is called to notify that there is an incoming call, and a screen display is displayed indicating that the incoming call is received from the terminal 2A, such as “coming from the terminal 2A”.
As shown in FIG. 11 (b), when two callers (terminal 2A, terminal 2C) make a call operation to the same receiving terminal, a ringing tone is generated at the calling terminal 2A. It is displayed that the call is in progress, such as “Calling in progress”. Similarly, a ringing tone is generated at the terminal 2C on the transmission side, and it is displayed that the calling is in progress such as “calling in progress”.

  On the other hand, in the terminal 2B on the receiving side, for example, when the call from the terminal 2A is made first, as shown in FIG. 11 (a), a message indicating that “the terminal 2A is receiving a call” is displayed. Is done. From this state, when there is a further call from the terminal 2C, as shown in FIG. 11 (b), the messages “incoming reception from terminal 2A” and “incoming reception from terminal 2C” are displayed. The user is notified that the call is being made from 2A and the terminal 2C (that is, receiving a call). Here, in messages such as “receiving a call from the terminal 2A”, “receiving a call from the terminal 2C”, “receiving a call from the terminal 2A”, “receiving a call from the terminal 2C”, etc. displayed on the display unit, 2A "and" Terminal 2C ", but in actuality information such as the names of the users of the terminal 2A and the terminal 2C or the telephone number that the receiving user can recognize the person of the other party Is displayed.

  The display screen of the message notifying that the terminal 2A and the terminal 2C are receiving a call is displayed on the “calling side terminal selection item m1” for selecting which of the terminal 2A and the terminal 2C responds, and In addition, it also serves as a response selection screen for displaying a “guidance selection item m2” for selecting a guidance to be notified to a caller terminal that has not been selected as a reception target.

The selection item m1 of the transmission side terminal includes a message representing a terminal that is receiving a call such as “receiving a call from the terminal 2A” and “receiving a call from the terminal 2C” as selection items.
The selection item m2 of the guidance includes, for example, items such as “answer machine guidance”, “callback guidance”, and “recall guidance”.
Each of the selection items m1 and m2 can be selected by selecting any item by moving the cursor by a key operation or by touching the corresponding item on the display screen. It is like that.

Note that the guidance selection item m2 is, for example, a selection item that is not selected when any of the transmission side terminals is selected in the selection item m1 of the transmission side terminal (for example, in the case of FIG. 11B, “ The incoming call reception from the terminal 2C ”) is displayed at a position (for example, below the display position of the selection item not selected as shown in FIG. 11B).
That is, FIG. 11B shows that the terminal 2A is selected as the terminal to be received and the terminal 2C is not selected as the terminal to be received, and the guidance for the terminal 2C not selected as the terminal to be received is shown. As the selection item m2, there are three guidances of “answer machine guidance”, “call back guidance”, and “call back guidance”, which indicates that “answer machine guidance” with a check mark added is selected.

<Operation>
Next, the operation of this embodiment will be described.
<Operation when the user of the receiving terminal does not answer>
First, the operation of each unit when the user of the receiving terminal 2B is not responding to the transmission request from the transmitting terminals 2A and 2C will be described.
FIG. 12 and FIG. 13 are sequence diagrams showing the operation of each unit when a call request is made from the terminal 2C to the terminal 2B following the terminal 2A.
When the caller of the terminal 2A performs a call operation addressed to the terminal 2B, a “call request” (P1) addressed to the terminal 2B is transmitted from the terminal 2A to the MME 3. When the MME 3 receives the “call request” (P1) addressed to the terminal 2B, the MME 3 sends an “incoming area inquiry” (P2) to the customer information management database device 7 to inquire about the area information of the terminal 2B.

If the terminal 2B is within the service area, the customer information management database device 7 transmits a “terminated area inquiry response” (P3) to the MME 3 to notify which MME is managing the terminal 2B. In this case, it notifies that MME4 is managing.
The MME 3 transmits a “connection request” (P4) between the terminal 2A and the terminal 2B to the MME 4 that manages the terminal 2B, which is notified by the “arrival side inquiry inquiry response” (P3).

The MME 4 that has received the “connection request” (P4) between the terminal 2A and the terminal 2B makes a “call” (P5) to the terminal 2B and notifies that the connection request is made from the terminal 2A. Further, along with the start of “calling” (P5), the calling timer is started, and the measurement of the elapsed time after starting the calling to the terminal 2B is started (P6).
On the other hand, the MME 3 transmits a “connection request” (P4) to the MME 4, and then transmits an “RBT activation request” (P7) to the sound source server 5 to request transmission of ringing tone information addressed to the terminal 2A. To do.

When the sound source server 5 receives the “RBT activation request” (P7) from the MME 3, the sound source server 5 transmits an “RBT activation response” (P8) to the MME 3, and calls sound information to the terminal 2A accompanying the call processing addressed to the terminal 2B. (P9) and the ringing tone information is transmitted (P10).
Thereby, in the terminal 2A on the transmission side, a ringing sound that means that the terminal 2B is being called flows. Further, as shown in FIG. 11A, a message indicating that a call is being made is displayed on the screen of the terminal 2A on the transmission side.

On the other hand, in the terminal 2B on the receiving side, a call is made such that a ringing tone is generated, and a message indicating that the incoming call is received from the terminal 2A is displayed on the screen as shown in FIG.
As described above, when the user of the terminal 2B on the receiving side is not responding to the call from the terminal 2A and the caller of the terminal 2C performs a call operation to the terminal 2B, “ A “transmission request” (P11) is transmitted from the terminal 2C to the MME 3.

Upon receiving the “call request” (P11) addressed to the terminal 2B, the MME 3 transmits a “calling area inquiry” (P12) to the customer information management database device 7 to inquire about the area information of the terminal 2B.
If the terminal 2B is within the service area, the customer information management database device 7 transmits a “terminated area inquiry response” (P13) to the MME 3 to notify that the MME 4 is managing the terminal 2B.

The MME 3 transmits a “connection request” (P14) between the terminal 2C and the terminal 2B to the MME 4 that manages the terminal 2B, notified by the “arrival side inquiry inquiry response” (P13).
Receiving the “connection request” (P14) between the terminal 2C and the terminal 2B, the MME 4 resets the call timer at this point (P15), and again measures the elapsed time since starting the call from this point. Start. Then, “call” (P16) is performed to the terminal 2B to notify that the connection request is made from the terminal 2C.

  That is, if the call timer is not reset, there is a possibility that a call will be timed out at a stage before the call at the terminal 2B is made for a predetermined period of time due to a connection request from the terminal 2C. In that case, there is a possibility that the terminal 2C side may determine that the connection is impossible when the calling time is shorter than usual, that is, the terminal 2C user may feel uncomfortable. As described above, when the “connection request” from the terminal 2C is received, by resetting the call timer, a sufficient call time can be secured even for the “connection request” from the terminal 2C. It is possible to avoid giving the 2C user an uncomfortable feeling.

In the terminal 2B to which “call” (P16) is notified, the process for the call continues. That is, the terminal 2B is notified that there is an incoming call by generating a ringing tone (P17).
On the other hand, the MME 3 transmits a “connection request” (P14) to the MME 4, and then transmits an “RBT activation request” (P18) to the sound source server 5 to address the terminal 2C accompanying the call processing addressed to the terminal 2B. Request to send ringing tone information.

Upon receiving the “RBT activation request” (P18) from the MME 3, the sound source server 5 recognizes that it is a request for transmitting ringing tone information addressed to the terminal 2C accompanying the second call processing to the terminal 2B (P19). , “RBT activation response” (P20) is transmitted to the MME 3, and ringing tone information is transmitted to the terminal 2C on the transmission side (P21).
As a result, the calling sound that means that the terminal 2B is being called also flows in the terminal 2C on the transmission side. In addition, as shown in FIG. 11B, a message indicating that the call is in progress is displayed on the screen of the terminal 2C on the transmission side.

On the other hand, in the terminal 2A on the transmission side, processing such as a ringing sound is continuously performed, and a message indicating that the calling is in progress is displayed on the screen.
On the other hand, when the terminal 2B on the receiving side receives the “call” (P16) from the MME 4 and is notified that the connection request is made to the terminal 2B from the terminal 2C, there are two incoming calls. As shown in FIG. 11B, two pieces of caller information are displayed. That is, the selection item m1 of the caller terminal for selecting which of the terminal 2A and the terminal 2C to respond to is displayed.

Thereby, the user of the terminal 2B can recognize that the incoming call is simultaneously received from the terminal 2A and the terminal 2C.
At this time, if the user of the terminal 2B cannot respond to the call, as shown in FIG. 12, the response to the call (P5) accompanying the call request of the terminal 2A and the call request of the terminal 2C Since the response (P22) to the call (P16) cannot be received by the MME 4, when the preset time-out time elapses from the time when the call (P16) accompanying the transmission request of the terminal 2C is transmitted, It is determined that the timer has expired (P23).

When the MME 4 determines that the “call timer has expired” (P23), the MME 4 transmits a “connection response (timeout)” addressed to the terminal 2A and a “connection response (timeout)” (P24) addressed to the terminal 2C to the MME3.
The MME 3 receives the “calling side phone book confirmation request” for requesting confirmation of whether the caller number of the user of the terminal 2A is registered in the phone book information of the user of the terminal 2B, and the caller number of the user of the terminal 2C. Then, a “calling side phone book confirmation request” (P25) for requesting confirmation of whether or not it is registered in the phone book information of the user of the terminal 2B is transmitted to the customer information management database device 7.

The customer information management database device 7 refers to the phone book information of the user of the terminal 2B, and determines whether the caller number of the user of the terminal 2A is registered in the phone book. Similarly, it is determined whether the caller number of the user of the terminal 2C is registered (P26).
As a result of searching the phone book information, the caller terminal corresponding to the user who is not registered in the caller's phonebook of the callee side terminal 2B among the caller numbers of the caller side terminals 2A and 2C (P31). ), Processing when the phone book is not registered is performed (P32).

  On the other hand, for the registered calling side terminal in which the telephone number of the calling side terminal user is registered in the user's phone book of the receiving side terminal 2B, the customer information management database device 7 stores the priority order information holding unit 51c. Referring to the priority information corresponding to the user of the receiving terminal 2B, it is determined whether the priority of the registered user of the transmitting terminal is set as the priority information (P33).

  Of the registered caller terminals, the caller terminal for which the user priority is set is set according to the set priority, and the user of the callee terminal 2B responds according to the priority. The response time is assigned in order from the latest possible time zone. And the process at the time of response time notification is performed, and the set response time is notified to the caller terminal (P34).

On the other hand, for the calling side terminal for which the user priority is not set, the schedule information of the user of the receiving side terminal 2B is referred to, and the most recent schedule with the user of the receiving side terminal 2B is supported. It is determined whether there is a caller terminal (P35).
In addition, when there is only one calling side terminal for which the user priority is not set, this calling side terminal is set as the next highest priority after the calling side terminal for which the user priority is set, and the response possible time Is assigned.

  Then, in the customer information management database device 7, for the calling side terminal corresponding to the user whose schedule with the user of the receiving side terminal 2B is registered most recently, the calling side corresponding to the user whose schedule is registered most recently The terminal is assigned a higher priority, and the nearest time zone in which the user of the receiving terminal 2B can respond is assigned in descending order of priority.

Note that, as a result of the determination under other conditions, the available response time may be set except for the available response time zone that has been set as the available response time of the other called terminal. Or when the time zone which can respond is comparatively long, you may set the time zone which can respond the same with respect to several origination side terminals as a response possible time. Similarly, when assigning the subsequent response time, it may be set in consideration of whether it is the time zone assigned as another response time.
And the process at the time of response time notification is performed, and the set response time is notified to the caller terminal (P36).

On the other hand, for the caller terminal corresponding to the user who has not been registered with the user of the callee terminal 2B most recently, is there a caller terminal corresponding to the user set as “favorite” in the phone book? It is determined whether or not (P37).
Then, regarding the calling side terminal corresponding to the user set as “favorite” in the phone book, the priority of the calling side terminal corresponding to the user who is not registered in the favorites is higher than that of the calling side terminal 2B. The latest available time zone is assigned as the available response time (P38). If there are a plurality of calling side terminals corresponding to the user set as “favorite”, for example, in the order of receiving calls to the receiving side terminal 2B, that is, in the order in which a call request is made to the receiving side terminal 2B. Therefore, the priority order may be set.

  On the other hand, for the caller terminal corresponding to the user who is not set as “favorite” in the phone book, the schedule information of the user of the caller terminal and the user of the callee terminal 2B who have not assigned a response available time is acquired ( P39), search for the response time of each user for the calling side terminal and the receiving side terminal 2B to which no response available time is assigned (FIG. 9), and search for those that overlap the time zone as the response available time of both To do. That is, a search is made for a match in the time zone as the response available time or a match in a part of the time zone as the response available time (P40).

  And, when there is a calling side terminal that overlaps a time zone in which the user of the calling side terminal can respond and a time zone in which the user of the receiving side terminal can respond, among the calling side terminals that have not assigned a response available time, That is, when there is a caller terminal that overlaps the time zone in which the user's schedule is available and the user of the callee terminal can respond (P41), the available response time of the user of the caller terminal and the callee terminal The response possible time of the calling side terminals that overlap each other is set as the response available time for the calling side terminal to which no response available time is assigned (P42). On the other hand, when the response time of both does not overlap, it is determined that the priority is higher in the order of arrival, and the response time is assigned in order from the latest time zone in which the user of the receiving terminal 2B can respond (P43). .

  If the response time of the user of the calling terminal matches the response time of the user of the receiving terminal, the overlapping response time may be set as the response time of the calling terminal. On the other hand, when a part of the response time of the user of the caller terminal and the callee terminal overlaps, only the overlapping time zone may be set as the response time of the caller terminal.

  Or you may set either the response possible time of the user of a transmission side terminal, or the response possible time of the user of a receiving side as a response possible time of this transmission side terminal. That is, since the time zone registered as the schedule information is, for example, an interval of 30 minutes, various schedules such as a meeting may end in a time shorter than the time zone as a response available time. Therefore, the time that can be set as the response time of the caller terminal by setting the time zone in which the user of the caller terminal or the callee terminal can respond as the response time of the caller terminal that should set the response time Since the number of bands increases, for example, it is possible to set a more recent time period as a response possible time, and usability can be further improved.

This completes the allocation of the response time for all “sender terminals that should be notified of the response time”.
FIG. 14 is a sequence diagram showing an example of processing when the phone book is not registered (P32) and processing when a response time is notified (P34).
In the customer information management database device 7, of the calling side terminals 2A and 2C, the calling side terminal whose caller number is not registered in the phone book (P31) (No caller ID registration) "(P32a) is transmitted to notify that the telephone number of the user of the calling terminal not registered in the telephone book is not registered in the telephone book of the user of the receiving terminal 2B. In the case of FIG. 14, a case is shown in which the users of the terminals 2A and 2C on the calling side are not registered in the telephone book of the terminal 2B on the receiving side.

When the MME 3 receives the “calling side phone book confirmation response (no caller ID registration)” (P32a), both the calling side terminal 2A and 2C users are registered in the receiving side terminal 2B user's phone book. Recognizing that there is no such message, a “call response (connection impossible)” (P32b) is transmitted to the unregistered caller terminals 2A and 2C.
When the outgoing side terminals 2A and 2C that are not registered in the telephone book receive the outgoing response (cannot be connected) (P32b), the incoming side terminal 2B performs processing such as displaying a screen indicating that the incoming side is not available. The users of the outgoing side terminals 2A and 2C that are not registered in the phone book can recognize that the other party (the incoming side terminal 2B) does not respond from the message displayed on the screen or the ringing sound continuing.

On the other hand, the customer information management database device 7 selects the calling side terminal for which priority is set for the user among the registered calling side terminals whose user caller numbers are registered in the phone book (P33). ), A response time is set, and this is notified to the caller terminal (P34).
Specifically, in the customer information management database device 7, if it is confirmed that the telephone number of the user of the calling terminal is registered in the telephone book of the user of the receiving terminal 2B, then the customer terminal 2B The user's schedule information is referred to and the response time of the user of the receiving terminal 2B is searched in consideration of the priority in the above procedure (P34a).

Here, for the sake of explanation, a case will be described in which both terminals 2A and 2C on the transmission side are registered in the telephone directory of the user of terminal 2B on the reception side.
In this case, the response possible time is set at the same timing for the transmitting terminal 2A and the transmitting terminal 2C. Therefore, it is determined as the same group. For example, if priority is set as priority information for the user of the transmission side terminal 2A, a response possible time is assigned to the transmission side terminal 2A first. That is, the most recent response possible time among the response possible times of the receiving side terminal 2B is assigned as the response possible time of the calling side terminal 2A. The caller side terminal 2C is assigned the next available response time among the available response times of the callee side terminal 2B.

  And, for example, information indicating that the calling side terminal 2A and the calling side terminal 2C are in the same group, and information indicating that the user of the calling side terminal 2A, for example, has a higher priority in this group, The retrieved response time is associated with the registered users of the sending terminals 2A and 2C and the user of the receiving terminal 2B, and stored as a response time notification history in a preset response time notification history storage area. .

Then, the customer information management database device 7 transmits a “calling side telephone directory confirmation response (with caller number registration)” (P34b) to the MME 3, and that the caller number is registered in the MME 3, and The response available time assigned to the caller terminal 2A and the response available time assigned to the caller terminal 2C are notified.
When MME3 receives “Called side phone book confirmation response (with caller ID registered)” (P34b), MME3 sends “Called response (cannot be connected)” (P34c) to terminals 2A and 2C, which are registered caller terminals. To do.

  When the registered transmission side terminal receives the transmission response (connection is impossible) "(P34c), it performs processing such as displaying on the screen that the reception side terminal 2B does not respond. Thereby, the user of the registered transmitting terminal can recognize that the other party (the receiving terminal 2B) does not respond because the message displayed on the screen or the ringing tone continues to ring.

  On the other hand, the MME 3 sends a “message creation request” (P34d) to the SMS / mail creation server 6 after sending a “call response (connection impossible)” (P34c) to the registered caller terminal. Callable side terminal 2B respondable time notified by "Callee side telephone directory confirmation response (with caller ID registration)" (P34b) received from customer information management database device 7 and calling side terminal with which the calling side terminal has been registered This is notified to the SMS / mail creation server 6. Also, the response time stored in the response time notification history storage area as the response time notification history, the time when the “message creation request” (P34d) is transmitted, Stored in association with the user of the receiving terminal 2B.

Since the SMS / mail creation server 6 has received the “message creation request” (P34d), the terminal 2B on the receiving side is used based on the notified response available time using a preset fixed sentence or the like. A response available time notification message addressed to the terminal 2A and the terminal 2C to notify the user available response time is generated (P34e).
Then, the SMS / mail creation server 6 sends a “message creation response” (P34f) to the MME 3, thereby notifying the MME 3 of the generated response time notification message addressed to each terminal.

Upon receiving the “message creation response” (P34f), the MME 3 sends a “message notification” (P34g) to each of the terminals 2A and 2C by SMS or e-mail, and the response available time notified by the “message creation response”. The notification message is transmitted to the registered outgoing terminals 2A and 2C.
As a result, the registered users of the transmission side terminals 2A and 2C, that is, the caller, can recognize the response time of the user of the reception side terminal 2B by referring to the notified response time notification message.
It should be noted that the processing at the time of response available time notification at P36, P38, P42, and P43 in FIG.

As described above, the caller cannot directly make a voice call with the callee, that is, a party who desires a voice call. However, the caller requests a user of the called terminal 2B, that is, a voice call by a response time notification message The other party is notified of the response time. For this reason, since a call is made during the notified response available time, it can be recognized that a call can be made with a partner who desires a voice call at this point.
At this time, if there are multiple caller terminals that should be notified of the response time, the priority of the user of the caller terminal is determined, the response time is set in consideration of the priority, and this is notified. It is configured to do. Therefore, an earlier time zone can be set as an available response time for a destination with higher priority.

<Operation during automatic line connection>
Next, the operation at the time of automatic line connection between the transmitting side terminal of the transmission destination of the response time notification message and the receiving side terminal of the transmission source will be described.
FIG. 15 is a flowchart showing an example of a processing procedure of inter-terminal automatic connection processing executed by the customer information management database device 7.
The customer information management database device 7 executes the inter-terminal automatic connection process at a preset fixed period (for example, equivalent to a unit width of a time zone that can be set as a response available time). As a result, the response available time notification history stored in the response available time notification history storage area is monitored at regular intervals, and it is determined whether or not there is a terminal subject to automatic connection between terminals.

That is, among the history data of the response time notification history, there is history data whose start time of the time zone set as the response time is within a predetermined time, that is, there is history data with the latest response time. Is determined (step S1).
If the corresponding history data does not exist, it is determined that there is no terminal that is a target of automatic connection between terminals. Then, the process ends.

On the other hand, in the history data of the response time notification history, when the start time of the time zone set as the response time is within the predetermined time and there is history data with the latest response time, the process goes to step S2. It is determined whether there is a plurality of history data in which the same time zone is set as the response possible time.
Then, when there are a plurality of history data in which the same time zone is set as the response possible time, priority is determined for these history data (step S3). Then, the process proceeds to step S4.

  For example, as described above, when all of a plurality of history data set with the same time zone belong to the same group, the determination is made according to the priority set in the history data. Further, when a plurality of history data in which the same time zone is set belong to different groups, for example, the earlier the timing when the response possible time is notified to the caller terminal, the higher the priority You may judge. That is, first, the priority order may be determined in units of groups, and then the priority order may be determined within each group. In this case, when the response time is stored in the response time notification history, for example, the time information is also stored in association with the response time, and the response time is based on this time information. What is necessary is just to judge the timing notified to the terminal.

The determination is not limited to this, and the determination may be made in the same procedure as when response time is assigned by the response time adjustment unit 53c.
On the other hand, if there is not a plurality of history data in which the same time zone is set in the process of step S2, the process proceeds to step S4 as it is.
In this step S4, the response possible time, the transmission source terminal and the transmission destination terminal are transmitted to the 3PCC server 8 in order from the history data with the highest priority, and the activation is instructed.

  Then, the automatic connection process is performed by the 3PCC server 8, and the processing result by the automatic connection process is received from the 3PCC server 8 (step S5). When it is notified that the connection by the automatic connection process has been established, The process proceeds to S6, and the corresponding history data is deleted from the response time notification history stored in the response time notification history storage area (step S7). Then, the process proceeds to step S8.

On the other hand, when it is notified from the 3PCC server 8 that the connection has not been established as a result of the automatic connection process, the process directly proceeds to step S8.
In step S8, it is determined whether or not the connection by the automatic connection process between the terminals is established for all the history data searched as the history data with the latest response time, and if it is established, the process is terminated. If it is not established, that is, if automatic connection between terminals has already been attempted, but the user has not been able to connect without responding, or if automatic connection between terminals has not yet been performed, the process goes to step S4. Transition. And the terminal information etc. are notified to the 3PCC server 8 about the history data whose priority is the next order. Note that history data that has already been automatically connected but could not be connected may be automatically connected again after all the history data is automatically connected.

If connection is not possible even after repeated automatic connection is repeated a predetermined number of times in advance, that is, if the user does not respond, for example, the response time may be set again.
Thus, the automatic connection process between terminals in the customer information management database device 7 is completed.
That is, in the customer information management database device 7, when the response possible time notified by the response available time notification message is reached, the transmission side terminal and the reception side terminal are transmitted to the transmission side terminal that has transmitted the response available time notification message. Are automatically called to realize a situation in which a voice call can be forcibly made.

  Therefore, it is not necessary for the user of the caller terminal or the user of the callee terminal to perform a call operation during the notified response possible time, and since a call is automatically made from the 3PCC server 8 at that time, Even if the user of the receiving terminal forgets to make a call, a voice call can be reliably established between the two.

<Operation when selecting the receiving terminal to receive>
Next, an operation in the case where the user of the receiving terminal 2B selects the receiving terminal to be received in response to a call request from the transmitting terminals 2A and 2C will be described.
FIG. 16 is a sequence diagram in the case where either the terminal 2A or 2C on the transmission side, which is requested to be transmitted from the terminal 2C following the terminal 2A, is selected as the reception target terminal on the terminal 2B. is there.
When the caller of the terminal 2A performs a call operation addressed to the terminal 2B, a “call request” (P51) addressed to the terminal 2B is transmitted from the terminal 2A to the MME 3. Upon receipt of the “call request” (P51) addressed to the terminal 2B, the MME 3 sends a “terminated area inquiry” (P52) to the customer information management database device 7 to inquire about the area information of the terminal 2B.

If the terminal 2B is within the service area, the customer information management database device 7 transmits “incoming area inquiry response” (P53) to the MME 3 to notify which MME is managing the terminal 2B. In this case, it notifies that MME4 is managing.
The MME 3 transmits a “connection request” (P54) between the terminal 2A and the terminal 2B to the MME 4 that manages the terminal 2B, which is notified by the “arrival side inquiry inquiry response” (P53).

The MME 4 that has received the “connection request” (P54) between the terminal 2A and the terminal 2B makes a “call” (P55) to the terminal 2B to notify that the connection request is made from the terminal 2A. Also, along with the start of “calling” (P55), the calling timer is started, and measurement of the elapsed time since the calling to the terminal 2B is started is started (P56).
On the other hand, the MME 3 transmits a “connection request” (P54) to the MME 4, and then transmits an “RBT activation request” (P57) to the sound source server 5 to request transmission of ringing tone information addressed to the terminal 2A. To do.

When the sound source server 5 receives the “RBT activation request” (P57) from the MME 3, the sound source server 5 transmits an “RBT activation response” (P58) to the MME 3, and calls sound information to the terminal 2A accompanying the call processing addressed to the terminal 2B. (P59) and the ringing tone information is transmitted (P60).
Thereby, in the terminal 2A on the transmission side, a ringing sound that means that the terminal 2B is being called flows. Further, as shown in FIG. 11A, a message indicating that a call is being made is displayed on the screen of the terminal 2A on the transmission side.

On the other hand, in the terminal 2B on the receiving side, a call is made such that a ringing tone is generated, and a message indicating that the incoming call is received from the terminal 2A is displayed on the screen as shown in FIG.
As described above, when the user of the terminal 2B on the receiving side is not responding to the call from the terminal 2A and the caller of the terminal 2C performs a call operation to the terminal 2B, “ "Call request" (P61) is transmitted from the terminal 2C to the MME 3.

When the MME 3 receives the “call request” (P61) addressed to the terminal 2B, the MME 3 sends an “incoming area inquiry” (P62) to the customer information management database device 7 to inquire about the area information of the terminal 2B.
If the terminal 2B is within the service area, the customer information management database device 7 transmits “incoming area inquiry response” (P63) to the MME 3 to notify that the MME 4 is managing the terminal 2B.

The MME 3 transmits a “connection request” (P64) between the terminal 2C and the terminal 2B to the MME 4 that manages the terminal 2B, notified by the “arrival side inquiry inquiry response” (P63).
Receiving the “connection request” (P64) between the terminal 2C and the terminal 2B, the MME 4 resets the call timer at this point (P65), and again measures the elapsed time since starting the call from this point. Start. Then, “call” (P66) is made to the terminal 2B to notify that the connection request is made from the terminal 2C.

On the other hand, the MME 3 transmits a “connection request” (P64) to the MME 4 and then transmits an “RBT activation request” (P67) to the sound source server 5 to address the terminal 2C accompanying the call processing addressed to the terminal 2B. Request to send ringing tone information.
Upon receiving the “RBT activation request” (P67) from the MME 3, the sound source server 5 recognizes that this is a request for transmitting ringing tone information addressed to the terminal 2C accompanying the second call processing to the terminal 2B (P68). , “RBT activation response” (P69) is transmitted to the MME 3, and ringing tone information is transmitted to the terminal 2C on the transmission side (P70).

As a result, the calling sound that means that the terminal 2B is being called also flows in the terminal 2C on the transmission side. In addition, as shown in FIG. 11B, a message indicating that the call is in progress is displayed on the screen of the terminal 2C on the transmission side.
On the other hand, in the terminal 2A on the transmission side, processing such as a ringing sound is continuously performed, and a message indicating that the calling is in progress is displayed on the screen.

  On the other hand, the terminal 2B on the receiving side receives the “call” (P66) from the MME 4 and receives two incoming calls when notified from the terminal 2C that a connection request is made to the terminal 2B. Therefore, as shown in FIG. 11B, two pieces of caller information are displayed. That is, the selection item m1 of the calling side terminal for selecting which of the terminal 2A and the terminal 2C responds is displayed (P71).

Thereby, the user of the terminal 2B can recognize that the incoming call is simultaneously received from the terminal 2A and the terminal 2C.
Then, when the user of the terminal 2B selects one of the selection items m1 of the transmission side terminal and selects, for example, “receiving incoming call from the terminal 2A”, the terminal 2B refers to “receiving incoming call from the terminal 2A”. It is clearly indicated that the item has been selected by changing the display form of the item (P72). In addition, as shown in FIG. 11B, the selection item m2 for guidance is displayed on the screen corresponding to the item “receive incoming call from terminal 2C” of the terminal 2C that has not been selected.

When the user of the terminal 2B selects one of the guidance selection items m2 and, for example, selects “Voice mail guidance”, the terminal 2B selects this by adding a check mark to the “Voice mail guidance”. This is clearly indicated (P73).
When the selection item m1 of the calling side terminal and the selection item m2 of the guidance are selected in this way, the terminal 2B becomes the terminal not selected in the selection item m1 of the calling side terminal, in the case of FIG. 11B. Transmits a “call response (connection impossible) + connection impossible parameter” (P74) to the MME 4 as a response to the “call” (P66) addressed to the terminal 2B from the terminal 2C, and is selected by the guidance selection item m2. The guidance selection information (F1 to F3) for identifying the guidance is notified as a connection impossible parameter.

In the case of FIG. 11B, guidance selection information (for example, F1) for specifying “answer machine guidance” is notified. That is, the terminal 2B is notified that the connection with the terminal 2C is not possible and that “answering machine guidance” has been selected as the guidance to the terminal 2C.
When the MME 4 receives the “call response (connection impossible) + connection impossible parameter” (P74) from the terminal 2B to the terminal 2C, this is sent to the MME 3 as “connection response (connection impossible) + connection impossible parameter” (P75). Forward.

When the MME 3 receives “connection response (connection impossible) + connection impossible parameter” (P75), the MME 3 recognizes that the terminal 2B cannot be connected to the connection request from the terminal 2C to the terminal 2B, and On the other hand, “RBT disconnection request (connection impossible) + connection impossible parameter” (P76) is transmitted.
The sound source server 5 transmits “RBT disconnection response (not connectable) + not connectable parameter” (P77) to the MME 3 as a response to the “RBT disconnection request (not connectable) + not connectable parameter” (P76). Then, the sound source server 5 selects guidance information corresponding to the guidance selection information set as the connection impossible parameter from the guidance information set in advance (P78), and transmits the selected guidance information to the terminal 2C. (P79).

In this case, since “F1” is set as the guidance selection information, that is, “Voice mail guidance” is set, voice guidance for connecting to the voice mail service flows to the terminal 2C.
The MME 3 sends a “call response (disconnect)” (P80) addressed to the terminal 2C because the connection failure is notified by the “connection response (connection impossible) + connection impossible parameter” (P75). On the other hand, it is notified that the connection with the terminal 2B is impossible and the terminal 2B is disconnected. Since “F1” is set as the connection impossibility parameter, connection processing to the answering machine service is performed (P81).

Thereby, the user of the terminal 2C can leave a message by the answering service.
For example, when “F2” is set as the connection impossible parameter and the return guidance is selected, the MME 3 sends a “RBT disconnect request (connection impossible) + connection impossible parameter (“ F2 ")" (P76) is transmitted.
Therefore, the sound source server 5 selects guidance information corresponding to the loopback guidance specified by the connection disabling parameter “F2” and transmits it to the terminal 2C.
Thereby, in the terminal 2C, a message that the user side of the terminal 2B makes a return call flows.

Similarly, when “F3” is set as the connection impossible parameter and the redialing guidance is selected, the MME 3 sends a “RBT disconnection request (connection impossible) + connection impossible parameter (“ F3 ")" (P76) is transmitted.
Therefore, the sound source server 5 selects guidance information corresponding to the redemption guidance specified by the connection impossible parameter “F3” and transmits it to the terminal 2C.
As a result, at terminal 2C, a message for requesting another call is played.

  On the other hand, in the terminal 2B, when “call response (connection impossible) + connection impossible parameter” (P74) is transmitted to the MME 4, subsequently, the “call response (connection process)” (P82) addressed to the terminal 2A is sent to the MME 4. Send. Upon receiving the “call response (connection process)” (P82), the MME 4 transmits this to the MME 3 as a “connection response (connection process)” (P83), and the MME 3 transmits the “call response (connection)” (P84). Is transmitted to the terminal 2A on the transmission side. Thereby, a voice call between the terminal 2A and the terminal 2B becomes possible.

  With the above configuration, even if the receiving terminal user does not answer at the time of the outgoing call operation, the receiving terminal user can make a call again or make a call from here. It is possible to recognize the user's will, such as whether it is necessary to correct it. Therefore, it becomes easy to handle afterwards.

<Example of overall mobile communication system operation>
Next, an example of the operation of the entire mobile communication system will be described with reference to FIG.
FIG. 17 is a flowchart showing an example of the overall operation when a transmission request is made from the terminals 2A and 2C to the terminal 2B.
When a call origination operation is performed on the terminal 2B in the calling terminal 2A and a call request is transmitted (step S11), the MME 3 on the calling side inquires the customer information management database device 7 about the area information ( Step S12).

  If it is determined that the terminal 2B is out of the service area as a result of the inquiry about the area information, normal processing when the receiving terminal 2B is out of the service area is performed (step S13). For example, a request for out-of-service guidance for notifying the sound source server 5 that the sound source server 5 is out of service area is performed from the MME 3 on the transmission side, and the out-of-service guidance information is transmitted to the transmission-side terminal 2A. It can be recognized that the 2B user is out of service area.

On the other hand, when the receiving terminal 2B is within the service area, the process for the service area is performed.
That is, as shown in FIG. 18, when it is determined that the terminal 2B on the receiving side is in the service area as a result of the inquiry about the area information, the terminal 2B is called (step S41). That is, a “call” is transmitted from the MME 4 that manages the terminal 2B to the terminal 2B.

As a result, the terminal 2B performs processing for “calling”. For example, a ringing tone is generated to notify the user that there is an incoming call (step S42). Further, a screen display indicating that the incoming call is received from the terminal 2A is performed in FIG.
On the other hand, ringing tone information is transmitted from the sound source server 5 to the terminal 2A on the transmission side, and the ringing tone sounds at the terminal 2A to notify the user that the calling is being performed.

Then, if the user of the terminal 2B responds to the incoming call, the process proceeds to step S44 through step S43, and processing at the time of connection for connecting the terminal 2A and the terminal 2B is performed, and the terminal 2A and the terminal 2B Calls between the two are possible.
On the other hand, when a call is made to the terminal 2B in response to a call request from the terminal 2A, a call operation for the terminal 2B is further performed by the user of the terminal 2C, and the MME 3 receives the call request (step) S43), and in the same way as described above, the inquiring area information is inquired from the MME 3 on the calling side to the customer information management database device 7 (step S45). The normal processing is performed (step S46), and if it is within the service area, it is determined whether or not the call request is for the same terminal.

In this case, since the outgoing call request is made from the terminal 2A to the terminal 2B and further from the terminal 2C to the terminal 2B, the process proceeds from step S47 to step S48, and the terminal 2B On the other hand, a call accompanying a call request from the terminal 2C is made.
If it is not a call request addressed to the same terminal, an existing connection process is performed (step S44), and a connection process is performed between the caller terminal and the partner terminal notified by the call request. That is, a “call” is transmitted from the MME 4 that manages the terminal 2B to the terminal 2B.

As a result, the terminal 2B performs processing for “calling”. In this case, since the call has already been made in response to the call origination request from the terminal 2A, a ringing tone is continuously generated (step S49).
Subsequently, as shown in FIG. 11B, the sender information of the terminal 2A and the terminal 2C is displayed on the display unit of the terminal itself (step S50). That is, the selection item m1 of the caller terminal is displayed. On the other hand, the terminal 2A and the terminal 2B display that they are calling.

Returning to FIG. 17, as shown in FIG. 11B, the terminal 2 </ b> B displays that the terminal 2 </ b> A and the terminal 2 </ b> B are receiving a call, and receives one of the selection items m <b> 1 of the caller terminal. When selected as the target terminal (step S15), the process proceeds to step S16, and processing is performed when the user of the receiving terminal 2B can respond.
That is, as shown in FIG. 19, first, a selection item m2 of guidance to be transmitted to a non-reception target terminal that is not selected as a reception target terminal in the selection item m1 of the caller terminal is displayed (step S51). ).

When one of the guidance selection items m2 is selected by the user of the receiving terminal 2B (step S52), guidance selection information representing the selected guidance item is set as a connection disable parameter.
No connection between the terminal 2C and the terminal 2B that is not connected between the non-receiving target terminal (for example, the terminal 2C) and the receiving terminal 2B that is not selected as the receiving target in the selection item m1 of the caller terminal Time process is performed (step S53), and a call response (not connectable) is transmitted to the terminal 2C. At this time, a connection impossible parameter is transmitted together with a call response (connection impossible).

Then, the guidance information corresponding to the connection impossible parameter is transmitted from the sound source server 5 to the terminal 2C (step S54). By listening to the notified guidance information, the user of the terminal 2C can recognize the will of the user of the receiving terminal 2B.
That is, since the user of the terminal 2B can recognize the user's intention such as whether he / she makes a call again or needs to make a call again from here, the user's intention can be understood. It becomes easy to do.

On the other hand, in parallel with the processing of steps S53 and S54, the terminal 2A, the terminal 2B, and the terminal 2B between the terminal (for example, the terminal 2A) selected as the reception target terminal by the selection item m1 of the sender terminal and the receiving terminal 2B, Is connected (step S55), and a voice call between the terminal 2A and the terminal 2B becomes possible.
Returning to FIG. 17, since the process when the response is possible in step S <b> 16 is completed, the process proceeds to step S <b> 17 and the process is terminated.

  On the other hand, when the user of the terminal 2B cannot respond to the call in step S15 and the terminal to be received is not selected in the selection item m1 of the caller terminal, that is, for example, a predetermined time set in advance. If the terminal to be received is not selected in the caller terminal selection item m1 even after the elapse, the process proceeds to step S18, and the caller information of the terminals 2A and 2C is registered in the telephone book of the user of the terminal 2B. It is determined whether or not. Then, for the unregistered terminal, the existing process is performed in the process of step S19, that is, the incoming terminal 2B continues to ring as it is.

On the other hand, when the caller information of the terminals 2A and 2C is registered in the phone book of the user of the terminal 2B, the process proceeds to step S20 and the process is continued.
In the process of step S20, it is determined whether there is a user whose priority is set by the user of the caller terminal 2B among the users of the caller terminals 2A and 2C. That is, with reference to the priority order information corresponding to the user of the calling terminal 2B, it is determined whether or not the priority is set for the users of the calling terminal 2A and the calling terminal 2C. If priority is set for either one, the process proceeds to step S21.

  In this step S21, a response available time is assigned according to the set priority order. That is, first, the schedule information of the user of the receiving terminal 2B is referred to, and a time zone in which the user of the calling terminal 2B can respond is searched as a response possible time. Then, the retrieved response time is allocated to the caller terminals 2A and 2C according to the set priority order.

For example, when the user of the transmission side terminal 2A has a higher priority, the latest response possible time is assigned to the transmission side terminal 2A. In addition, when priority is set for one of the users of the calling side terminals 2A and 2C, but priority is not set for the other, the priority is assigned to the user. Assign a more recent response time. Then, a response available time notification message for notifying this response available time is generated for each terminal, and this is addressed to the terminal to which the user of the receiving terminal 2B cannot respond (addressed to the sending terminals 2A and 2C or To one of them).
And a process is complete | finished (step S17).

  On the other hand, if no priority is set by the user of the caller terminal 2B for any user terminal of the caller terminals 2A and 2C in step S20, the process proceeds to step S22, and the callee terminal 2B. A response available time is assigned according to whether or not it is registered in the latest schedule of the user (step S23). That is, first, the response possible time of the user of the receiving terminal 2B is searched by the same procedure as described above. Next, with reference to the schedule information of the user of the receiving terminal 2B, it is determined whether a schedule with the user of the transmitting terminal 2A or 2C is registered as the latest schedule. And when the schedule with the user of any calling side terminal is registered, the calling side terminal corresponding to the registered user is regarded as having a high priority, and it corresponds to the user registered in the latest schedule. Assign the most recent response available time to the terminal. Then, a response available time notification message for notifying this response available time is generated for each terminal, and this is addressed to the terminal to which the user of the receiving terminal 2B cannot respond (addressed to the sending terminals 2A and 2C or To one of them). And a process is complete | finished (step S17).

On the other hand, if none of the users of the caller terminals 2A and 2C is registered in the most recent schedule of the user of the caller terminal 2B in step S22, the process proceeds to step S24 and is set as “favorite” in the phone book. A response time is assigned based on whether there is a terminal to which the user is registered (step S25).
That is, first, the response possible time of the user of the receiving terminal 2B is searched by the same procedure as described above. Next, with reference to the telephone directory information of the user of the receiving terminal 2B, it is determined whether any one of the users of the transmitting terminals 2A and 2C is registered in “favorites”.

  If either one is registered in “favorites”, the latest response available time is set for the terminal corresponding to the user registered in “favorites”. Then, a response time notification message for notifying the response time is generated for each terminal, and this message is transmitted to the terminal to which the user of the receiving terminal 2B has not responded. And a process is complete | finished (step S17).

On the other hand, if none of the users of the caller side terminals 2A and 2C is registered in the “favorites” of the user's phone book of the caller side terminal 2B in step S24, the process proceeds to step S26, and the caller side terminal 2A And 2C user's schedule information is referred to search for a response time zone.
Similarly, a response time zone is searched with reference to the schedule information of the user of the receiving terminal 2B. These response time zones are matched (step S27).

If there is a terminal out of the originating side terminals 2A and 2C where the user's response time zone overlaps with the user's response time zone of the receiving side terminal 2B, the process proceeds to step S30. For example, the response possible time of the receiving terminal 2B including the overlapping time zone is assigned to the terminal with which the possible time zones overlap.
For the other terminal, for example, another time zone is allocated among the time zones in which the receiving terminal 2B can respond. And a process is complete | finished (step S17).

  In the process of step S29, if there is no terminal in which the time zone in which the user can respond matches the time zone in which the user of the receiving terminal can respond, the process proceeds to step S30, and the transmitting terminals 2A and 2C Among them, the earlier the timing of making a call request to the receiving terminal 2B, the higher the priority, and the higher the priority, the more recent response possible time is allocated. And a process is complete | finished (step S17). In this case, first, since the user of the calling terminal 2A is performing a calling operation, it is determined that the calling terminal 2A has a higher priority, and the calling terminal 2A is assigned a more recent response time. It is turned on.

As described above, the processing when a call request is made from the caller terminal is completed.
Then, the customer information management database device 7 performs the automatic connection process between terminals shown in FIG. 15 described above, and when the response possible time notified by the response available time notification message is reached, the calling terminal and the receiving terminal are notified. The 3PCC server 8 is automatically called. If the users of the calling side terminal and the called side terminal both respond, a line connection is made between the calling side terminal and the called side terminal, and a voice call can be made between them.

<Summary>
As described above, the customer information management database device 7 is configured to manage the schedule information of each terminal. When the terminal 2B on the receiving side does not respond to the ringing tone, the terminal 2B on the receiving side The response available time is searched from the user's schedule information, and the searched response available time is transmitted to the terminals 2A and 2C on the transmission side by a response available time notification message. For this reason, the caller side terminals 2A and 2C can recognize when they can make a voice call with the user of the terminal 2B by referring to the notified response time notification message. , Can improve usability.

Further, when setting the response time, the response time is assigned in consideration of the priority of the user of the calling terminal. Therefore, it is possible to assign a response time in consideration of the degree of urgency when contacting the user of the calling terminal, and usability can be further improved.
Further, since the setting of the response time and the transmission of the response time notification message are all performed on the server side, it can be realized without taking time and effort for the user of the receiving side terminal 2B.

  Furthermore, when the notified response time is reached, a call is automatically made to the notification destination terminal and the called terminal that notified the response time, and when the users of both terminals respond, Because the line connection is configured, the user of the receiving terminal forgets to make a call to the calling terminal during the notified response time, or the user of the calling terminal intentionally makes a call again Thus, it is possible to make a voice call more reliably without taking time and effort.

  Further, at this time, it is determined whether or not the caller numbers of the users of the caller terminals 2A and 2C are registered in the phonebook of the user of the callee terminal 2B. Only the response time is notified. For this reason, the user of the receiving side terminal 2B, such as solicitation, wrong call, and telephone from a person who does not want to talk, will bother to notify the available time for a call request from a person who does not want to talk, Can be avoided.

Further, the schedule information and the telephone book of the user of each terminal are managed by the customer information management database device 7 instead of the terminal side. Further, the customer information management database device 7 searches for a response time, It is configured to search for and so on.
Here, when each terminal is configured to hold the schedule information and phone book of the user of the terminal, the terminal searches the schedule information and the phone book each time a response time notification message is transmitted. It is necessary to increase the load on the terminal. In addition, in order to suppress this load, even if the processing for searching the schedule information and the phone book is performed not on the terminal side but on another device side, information between the terminal and another device is also provided. Will also be accompanied by an increase in the load on the terminal.

  On the other hand, in the above-described embodiment, the schedule information and the telephone book of the user of each terminal are managed by the customer information management database device 7 instead of the terminal side, and the customer information management database device 7 can respond. The system is configured to perform time searches and phone book searches. Therefore, when realizing the present invention in which the response time notification message is transmitted, it can be realized without adding a function to a currently popular terminal. Therefore, versatility can be improved.

  Further, the customer information management database device 7 transmits the response time notification message. Therefore, when the terminal of the terminal on the receiving side cannot respond to voice at the time of incoming call, the terminal on the receiving side is out of service area when the terminal is turned off or before the response time notification message is transmitted to the calling terminal. Even in this case, it is possible to reliably notify the caller terminal of the response available time.

  The above is a case where the user of the receiving terminal 2B cannot respond to the call. In the mobile communication system 1 according to the present embodiment, the receiving terminal is further involved in a call request from another calling terminal during processing of a call addressed to the receiving terminal accompanying a call request from the calling terminal. In a state where there is a call to the terminal, that is, a ringing tone is ringing in response to a call request from a certain calling side terminal or a ringing tone is heard in the receiving side terminal, and there is an incoming call from the receiving side terminal. In this case, that is, when there are a plurality of incoming calls at the same time, the caller information is displayed on the terminal on the incoming side, and the user on the incoming side can select the terminal to be received.

Therefore, the user on the receiving side can arbitrarily select a caller to be received, that is, which caller to call. In addition, since the caller information is displayed on the terminal of the user on the called side, the caller can respond to the call from whom the call is made by referring to the caller information. Can be easily determined.
On the other hand, although it is not possible to respond to a call from a terminal that has not been selected as a reception target, a configuration is used in which guidance is notified to a partner that has failed to respond, as shown in FIG. In addition, the content of the guidance can be arbitrarily selected by the user of the receiving terminal.

Therefore, based on the caller specified from the caller information, the user can select a guidance suitable for the caller, or select an appropriate guidance according to the situation of the user of the receiving terminal. Communication with the other party that could not be done can be facilitated, and appropriate responses can be made.
In other words, for example, if there is no room to make a call even after the call with the other party who is answering is completed, such as when the called party is working, select the guidance that notifies you that you will be connected to the answering service, and immediately If you are ready to make a call, select the guidance to call back. As a result, the calling side cannot make a call directly with the user on the receiving side, but by listening to the guidance, it can be connected to the answering machine service, so that the message can be left, or the user of the receiving side terminal can call You can easily recognize that you will redeem.

  In addition, when it is not selected as a terminal to be received, it is configured to select the guidance addressed to the terminal that has not been selected, and the user selects the guidance every time there is an incoming call from the calling side terminal. Appropriate guidance can always be selected according to the situation at that time, and the caller's terminal that could not respond promptly to the call from the caller's terminal must be dealt with more carefully. Can do.

<Modification>
<Modified example when searching for response time>
In the above embodiment, as shown in FIG. 7, a case has been described in which it is determined whether or not a telephone response is possible from a schedule item set in the scheduler. However, the present invention is not limited to this.
For example, as shown in FIG. 20, while displaying the schedule of the day, a screen is provided on which the user can set a time zone in which telephone response is not possible for each time zone in which the schedule data is registered. You may comprise so that the time slot | zone which can respond may be searched according to a setting.

  That is, as shown in FIG. 20, a telephone response setting field for setting a time zone in which a telephone response is impossible is provided along with a time zone in which schedule data is set. Then, by designating a telephone response setting field corresponding to a time zone in which schedule data is set, such as “A meeting”, a check mark (× mark in FIG. 20) is displayed. Then, it is determined that the telephone response is impossible during the time zone in which this check mark is set. In the case of FIG. 20, check marks are displayed in the time zone in which “A meeting” is set, the time zone in which “B countermeasure correspondence” is set, and the time zone in which “E correspondence” is set. Therefore, it is determined that the time zone in which “A meeting”, “B countermeasure”, and “E” are set is unacceptable, and other time zones are determined as time zones in which the telephone can be answered.

In addition, a setting screen for setting a time zone in which telephone response is possible or a time zone in which telephone response is not possible is provided in units of 30 minutes per day, for example, instead of the unit in which schedule data is set in this way. You may do it.
In addition, for example, in the scheduler as shown in FIG. 7, the commuting time zone is usually not set. Therefore, when there is an incoming call in the commuting time zone, the commuting time zone is not registered in the schedule, and therefore, the commuting time zone may be searched as a response time zone.

Therefore, for example, a time corresponding to the commuting time zone is set in advance, and when there is an incoming call in this time zone, a response is made from a time zone after a predetermined time (for example, commuting time equivalent). It is good also as a structure which searches a possible time slot | zone. By doing in this way, it can avoid that a caller is notified as a time zone which can respond to a commuting time zone.
Further, in the above embodiment, when searching for a response possible time, a time zone including an unacceptable keyword that cannot make a telephone response is specified in the schedule data, and a time zone excluding the specified time zone is set as a response available time. However, the present invention is not limited to this.

  For example, if the scheduler is configured to identify and set external schedule items such as meetings and meetings and schedule items such as its own work schedule, the time zone in which its own work schedule is set May be set as a response possible time. For example, as shown in FIG. 7, in the scheduler, in the case of an external schedule item such as a meeting or a meeting, attendance / holding information is set.

  Further, in the case of an external schedule item such as a meeting or a meeting, the display form such as the background color may be changed and displayed. Therefore, it is determined whether or not it is a response time zone by determining whether or not attendance and hold information is set, or whether or not the display mode is a display mode representing a meeting or the like. You may do it.

<Modification with schedule update>
In the above embodiment, after sending the response available time to the calling terminal, the user of the receiving terminal 2B newly registers or changes schedule data in the time zone notified as the response available time. there's a possibility that. Therefore, depending on the case, there is a possibility that the time zone notified as the response possible time may be changed to a time zone where the response is impossible.
Therefore, when the schedule information of the user of the receiving terminal 2B is changed, it is monitored whether or not the time zone notified as the response available time is changed to a time zone in which the response is not possible. It is good also as a structure which notifies new response possible time.

  Further, when the schedule information is changed, if the configuration is such that a new response possible time is notified, after the response possible time is notified, it is the receiving side terminal and the transmission destination that are the transmission source of this response possible time. When a call, e-mail, SMS, or the like has been exchanged between the users of the calling terminal, the response time zone has already been changed by these calls, e-mails, etc. There is a possibility that the original requirement that the user called the user of the receiving terminal has been solved. In this way, if the answering time zone is changed or the original requirements are already resolved, if the new answering time is notified to the receiving terminal again, the user of the receiving terminal may be confused. There is sex.

Therefore, after notifying the available response time first, when a call, e-mail, SMS, etc. is being exchanged between users of the receiving terminal that is the transmission source and the calling terminal that is the transmission destination Even when the schedule information is changed, it is possible to further improve the usability by adopting a configuration in which re-notification of the response time is not performed.
That is, when the schedule of the user of the receiving terminal is updated, a scheduler update time processing unit is provided in the customer information management database device 7 as a processing unit for performing processing associated with this update. Then, as the scheduler update time processing unit, a re-notification determination unit that determines whether it is necessary to notify the response available time again, and a re-response possible time when it is determined that re-notification is necessary by the re-notification determination unit A re-transmission unit is provided.

In addition, a call history collection unit that stores a call history between each user and a mail communication history collection unit that stores a transfer history such as e-mail and SMS are provided.
Then, when the scheduler is updated, the scheduler update time processing unit resets the response available time, and retransmits it to the originating terminal.At this time, from the time when the response available time is notified first, Up to now, a new response time is notified only when a call, e-mail, or SMS has not been exchanged between the users of the sending terminal and the receiving terminal. Thereby, usability can be further improved.

The operation of each part in the case of such a configuration is as shown in a sequence diagram shown in FIG. 21, for example.
First, after a response time notification message is transmitted from the calling side terminal 2A to the receiving side terminal 2B, a voice call or mail exchange is not performed between the users of the calling side terminal 2A and the receiving side terminal 2B. The operation when the receiving terminal 2B newly registers (updates) the schedule data will be described.

When the user of the receiving terminal 2B newly registers or updates the schedule data (P101), a "new registration (update) notification to the scheduler" (P102) is sent from the receiving terminal 2B to the customer information management database device 7 Sent to.
When the customer information management database device 7 receives the “new registration (update) notification to the scheduler” (P102), the customer information management database device 7 manages the schedule data in the schedule information of the user of the receiving terminal 2B managed by the customer information management database device 7 New registration or update.
Further, the customer information management database device 7 determines whether it is necessary to re-notify the available response time (P103).

  That is, first, referring to the response available time notification history storage area, the user of the receiving terminal among the history data of the response available time notification history is the user of the terminal 2B that has newly registered (updated) in the scheduler, and It is determined whether or not there is a time zone that is set as a response available time and a time zone that is newly registered (updated) by the user of the receiving terminal 2B. In addition, there are cases where time zones overlap in this way, and when this time zone is changed to a non-response possible time when telephone response is not possible due to update of schedule data, it is necessary to re-notify the response time Judge that there is.

For example, the response time set in the response time notification message or the response time re-notification message sent to the calling terminal 2A first is a time zone in which the user of the receiving terminal 2B is newly registered (updated) If it overlaps, it is determined that there is a corresponding response time notification message.
In the customer information management database device 7, when it is determined that it is necessary to re-notify the available response time, the schedule information of the user of the terminal 2B is referred to again, and in the newly registered or updated schedule information, the predetermined time after the current time The response time within the time is searched (P104).

Then, new registration to the originating terminal (in this case, the terminal 2A) and the scheduler set in the history data from which it is determined that it is necessary to re-notify the retrieved response available time and the response available time ( The user of the terminal 2 </ b> B that performed the update) is associated with the current time, and this is stored in a response available time notification history storage area set in advance as a response available time notification history.
Further, the history data that is the basis for determining that it is necessary to re-notify the response available time is deleted from the response available time notification history storage area.

  Then, a “message re-transmission request” (P105) is transmitted to the SMS / mail creation server 6 and the outgoing call set in the history data from which it is determined that it is necessary to re-notify the available response time. A transmission request for a response available time re-notification message is made in order to re-notify the retrieved response available time with the side terminal (in this case, the terminal 2A) as the transmission destination.

  When receiving the “message re-transmission request”, the SMS / mail creating server 6 generates a response time re-notification message using, for example, a fixed phrase based on the notified response time (P106). Then, the SMS / mail creation server 6 transmits “message resend” (P107) to the customer information management database device 7 as a response to the “message resend request” (P105), along with the generated response time re-notification message. Then, it is notified that the destination terminal of the response available time re-notification message is the terminal 2A.

Upon receiving “message retransmission” (P107), the customer information management database device 7 sends “message retransmission” to the MME 3 where the terminal 2A designated as the transmission destination of the response available time re-notification message is located. (P108) is transmitted to notify that the response possible time re-notification message notified from the SMS / mail creation server 6 and that the transmission destination is the terminal 2.
The MME 3 sends “message retransmission” (P109) including the notified response time re-notification message to the terminal 2A notified as the transmission destination by the received “message retransmission” (P109) by SMS or e-mail. Send by.

  As a result, the user of the originating terminal 2A refers to the received response time re-notification message, so that the schedule is notified in the time zone notified as the response time of the user of the receiving terminal 2B that was previously notified. As a result, it can be recognized that it is sufficient to call the user of the terminal 2B during the response time newly notified by the current response time re-notification message. That is, the possibility that the user of the terminal 2A can make a voice call with the user of the terminal 2B can be increased.

  Then, the customer information management database device 7 transmits “message retransmission” (P108) to the MME 3, and then transmits “new registration (update) response to the scheduler” (P110) to the terminal 2B. Notifies that the new registration or update to the scheduler has been completed. As a result, the user of the terminal 2B recognizes that the process associated with the new registration or update of the schedule data has been completed, and ends the series of processes associated with the new registration (update) of the schedule data (P111).

  On the other hand, in the customer information management database device 7, when it is determined that the response time notification message has not been transmitted to another terminal as the response time in the time zone when the schedule data is newly registered (updated) In (P103), the "new registration (update) response to scheduler" (P121) is transmitted to the terminal 2B as it is. The terminal 2B recognizes that the new registration or update of the schedule data has been completed, and ends a series of processes accompanying the new registration (update) of the schedule data (P122).

With the above configuration, the user of the terminal 2A can accurately recognize the time for performing a voice call with the terminal 2B even when the schedule of the user of the terminal 2B is changed, that is, the usability Can be improved.
After sending a response time notification message to the calling terminal 2A, a response time re-notification message is sent to the calling terminal 2 along with the update of the schedule data in the receiving terminal 2B. If the schedule data is updated again at the receiving terminal 2B and the time period notified as the response available time by the previous response available time re-notification message is changed, the same processing as described above may be performed.

That is, in the response available time notification history storage area, the response available time, the sending terminal, the receiving terminal, and the time when these messages are stored when the response available time notification message and the response available time re-notification message are transmitted are stored. Stored in association.
Therefore, by searching the history data stored in the response time notification history storage area, it is necessary to retransmit the response time based on the history data when the response time re-notification message is transmitted. Will be judged.
The above is a situation where a voice call or mail exchange is performed between the caller terminal 2A and the callee terminal 2B after the response time notification message is transmitted from the callee terminal 2B to the caller terminal 2A. The operation when a new registration (update) of schedule data is performed.

Next, after a response time notification message is transmitted from the receiving terminal 2B to the calling terminal 2A, a voice call or mail exchange is performed between the calling terminal 2A and the receiving terminal 2B. The operation when the schedule data is newly registered (updated) will be described.
In the customer information management database device 7, the user of the receiving terminal 2B is the user of the terminal 2B who has newly registered (updated) the schedule data, and the time zone set as the response available time is that of the receiving terminal 2B. Even if there is something that overlaps with the time zone newly registered (updated) by the user, a voice call is made between the users of the originating side terminal 2A and the terminating side terminal 2B set in this response time notification history If the mail has already been exchanged, the response available time re-notification message is not transmitted.

  As described above, when the voice call or the mail is already exchanged between the caller and the callee, the response time re-notification message is not transmitted as described above. It is possible to avoid misunderstanding the user of the transmission side terminal 2A. That is, since the configuration is such that the response available time re-notification message is transmitted only when the situation is such that no misunderstanding is given to the user of the originating terminal 2A, the usability can be further improved.

<Modification example when determining whether or not to allow response time notification>
In the above-described embodiment, the response time notification is made only when the caller ID of the caller terminal is registered in the phonebook of the user of the callee terminal. However, the present invention is not limited to this.
For example, a notification destination table is provided for registering the telephone number of the other party who will be notified of the response time, and response time notification is made only for a call request from a terminal having a telephone number registered in the notification destination table. It is good also as composition which performs.

By adopting such a configuration, it is possible to notify the response available time only to the other party who really wants to perform the response available time notification. In other words, the phone book is not only for people who are close to you but also for people who are working with you or people who happen to exchange phone numbers. There are various people such as no one. Therefore, by configuring the notification of the response available time only for the telephone numbers registered in the notification destination table, it is possible to arbitrarily set the other party who performs the response available time notification.
The setting in the notification destination table is performed on the terminal side, and the management may be performed in the customer information management database device 7.

Conversely, a non-notification destination table for registering the telephone number of the other party who does not notify the response available time is provided, and for a call request from a terminal having a telephone number registered in this non-notification destination table, The response possible time notification may not be performed, and the response possible time notification may be performed only for a call request from a telephone number that is not registered in the non-notification destination table.
By adopting such a configuration, it is possible to avoid performing a response time notification to a partner who does not want to perform a response time notification.

  In addition, a response time is notified for a call request from a fixed phone, a response time is not notified for a call request from a phone number set as a call rejection setting, and the caller ID is notified. It is a call request from a terminal equipped with a caller ID notification function that can be set to be notified or not notified, and a response time is not notified for a call request from a terminal set as a caller ID non-notification It may be set.

  Further, in the case where each user's telephone directory has a function for group registration, the response time may be notified only to a call request from a person registered in the group. In this case, for example, a response time notification may be made only to a person registered in the first group, or registered in a plurality of groups such as the first group and the second group. It is good also as a structure which notifies a response possible time only with respect to a person.

In this way, whether or not the user himself / herself makes a response time notification by determining whether or not to perform the response time notification using the settings in the existing functions such as the phone book function and the incoming call rejection setting. It is possible to reduce the load when performing such setting.
In addition, as described above, the determination condition of the other party that performs the response time notification or the other party that does not perform the response time notification is not fixed, but the determination result of the determination condition is notified / not notified of the response time. It may be configured to arbitrarily set whether or not to be reflected in.

  In other words, for example, when the caller is a courier, the called party wants to notify the available response time and communicate without having to know the telephone number of the courier. Further, the home delivery service usually makes a call request as a caller ID notification. Therefore, in this case, the determination condition that the caller ID notification is set is set to “valid”, and a response time notification is made for a call request from the terminal set as the caller ID notification. By setting to perform, it is possible to notify the courier company of a response possible time, and for example, it is possible to smoothly receive a delivery package.

In addition, even when it is known in advance that there is a package delivery, it is possible to smoothly contact the courier by setting the judgment condition that the caller ID notification is set to “valid” It is possible and effective.
On the other hand, even when the caller ID notification is set, it may be a person who is not very familiar or a solicitation telephone. Therefore, normally, the determination condition for determining whether to notify / not notify the response time is set to “invalid” based on whether or not the caller ID notification is set. This makes it possible to determine whether to notify / not notify the response time regardless of whether or not the caller ID notification is set.

  In addition, the caller ID of the terminal that made the call request, for example, the caller who inquires with the list of telephone numbers registered as related to ole fraud provided on the homepage established by a public institution. A number inquiry processing unit may be provided, and when the telephone number is registered in the telephone number list registered in the caller number inquiry processing unit, the response possible time may not be notified.

  Also, when you receive a spam mail, if you know the telephone number corresponding to the sender of the spam mail from the spam mail destination address, save this telephone number, and the caller ID is the spam mail. When a telephone number corresponding to the spam number is matched, a response request time non-notification may be made for a call request from a terminal that matches the telephone number corresponding to the spam mail.

Further, the setting of notification / non-notification of the response possible time described above may be performed alone or in combination. Moreover, it may be configured so that it can be set individually for each terminal, or may be common to each terminal.
For example, whether the caller ID of the user of the caller terminal is registered in the phonebook of the user of the callee terminal, or is registered in the notification destination table for registering the phone number of the other party to whom the response time notification is made , Whether it is registered in the non-notification destination table where the other party's phone number whose response time is not notified is registered, whether the caller is a fixed phone, set as a call rejection setting, A determination condition setting unit is provided for setting whether to enable or disable a determination condition such as whether it is set as notification or whether the caller is a person registered in a group.

  Then, the determination is made only for the determination conditions that are valid in the determination condition setting unit, and the response time is determined only when it is determined that the response time can be notified in all the determination conditions. It is good also as a structure which notifies to. Alternatively, the response available time may be notified to the caller terminal only when it is determined that the response available time may be notified under the determination condition of the threshold value or higher among the determination conditions.

Note that the determination condition set by the determination condition setting unit may be set for each terminal, and the response possible time may be transmitted according to each determination condition for each terminal.
Also, when you receive a spam mail, if you know the telephone number corresponding to the sender of the spam mail from the spam mail destination address, save this telephone number, and the caller ID is the spam mail. When a telephone number corresponding to the spam number is matched, a response request time non-notification may be made for a call request from a terminal that matches the telephone number corresponding to the spam mail.

Moreover, in the said embodiment, only when the transmission side terminal is registered into the telephone directory of the user of the receiving side terminal, the response time of the user of the receiving side terminal is notified to the calling side terminal; However, the present invention is not limited to this.
For example, when the receiving terminal is not responding, the calling terminal is connected to the calling terminal regardless of whether the user of the calling terminal is registered in the telephone book of the user of the receiving terminal. It is good also as a structure which notifies a user's response possible time.

  In this case, for example, even a terminal that does not have a telephone directory function or a terminal that does not use the telephone directory function and is not registered in the telephone directory is set to caller ID notification as described above. If the response time is notified, the response time is notified to the person in accordance with the user's will of the receiving terminal 2B by combining the response time notification / non-notification setting described above. And can be unnotified.

<Modification example at call timer reset>
In the above embodiment, when the “connection request” is made from the terminal 2C while the terminal 2B is calling the “connection request” from the terminal 2A, the MME 4 uses the terminal 2C The case where the call timer is reset at the timing when the “connection request” is received from the terminal 2B and the call for the “connection request” from the terminal 2C is made to the terminal 2B has been described.

For example, a timer specified value setting unit that sets a specified value equivalent to the calling time of the calling timer is provided, and every time a "connection request" is made from another calling terminal while calling to the called terminal In addition, the call timer may be reset and the specified value may be variable so that the specified value becomes longer.
In other words, the user on the receiving side can respond sufficiently if the incoming call is received only from the first caller if the ringing time is a normal specified value (the first specified value, for example, about 10 seconds). it can.

  However, when there is an incoming call from the first caller and the second caller, the user on the receiving side recognizes who these first caller and second caller are, and It is necessary to determine which one is selected as the reception target. In other words, the user on the receiving side is, for example, a contact for emergency communication such as whether the caller is a business partner or boss, or an incoming call from a caller who is scheduled to meet in the near future and is delayed due to an emergency. It is necessary to select a reception target in consideration of the relationship with the caller from various viewpoints, such as whether the incoming call is predicted to be possible. For this reason, it may take a certain amount of time to select the reception target, and there is a possibility that the call time cannot be sufficiently examined with the normal specified value. Furthermore, not only the first caller and the second caller, but also the third caller and the fourth caller. As the number increases, the number of callers to be considered increases. It takes time to select

  Therefore, when there is an incoming call from the second caller during the call from the first caller, the timer value is reset and the timer specified value setting unit sets the timer value from the first specified value. Is set to a larger second predetermined value (for example, about 15 seconds). Thereby, since the time until the timer times out becomes longer, the user on the receiving side can fully consider which of the first caller and the second caller to select.

  Furthermore, when an incoming call is received from the third caller during a call from the first and second callers, the timer value is reset and the timer value is set to the second specified value by the timer specified value setting unit. It is set to a third specified value (for example, about 20 seconds) that is larger than the value. As a result, the user on the receiving side can fully consider which of the first, second, and third callers to select, and the time until the time out is increased by one more callers. Since the time is also extended, it can be fully considered.

In other words, in the timer specified value setting unit, the time until the timer times out becomes longer as the number of callers who make a “connection request” to the same receiver terminal increases during the call from the first caller. For example, every time one person increases, the specified value is set to a large value by a certain amount of time (in this case, 5 seconds).
As a result, the user on the receiving side can study with sufficient margin even when the receiving target is selected from a plurality of callers.

  In addition, it is not limited to the case where the time until timeout is set to be longer by a certain time every time one caller is added. For example, the time until timeout is gradually increased every time two callers are added. The key is to make it possible for the user on the receiving side to fully consider which caller to select as the target of reception when the number of callers increases. A prescribed value may be set. In addition, even if the time until timeout is too long, an upper limit value of the specified value may be provided and an upper limit may be provided for the timeout time in order to give a strange feeling to the caller and the user on the receiving side.

<Modified Example of Configuration of Terminals 2A to 2C>
In the said embodiment, although the case where the terminal corresponding to LTE was used as terminal 2A-2C was demonstrated, it is not restricted to this. It suffices that at least the terminal on the receiving side has a function of processing a plurality of incoming calls received simultaneously, such as an LTE compatible terminal.
In the above embodiment, the case where two terminals 2A and 2C simultaneously receive calls to terminal 2B has been described. However, the present invention is not limited to this, and three or more terminals simultaneously receive calls to one terminal. Even if there is.

In this case, if the terminal on the receiving side is configured to display the guidance selection item m2 for each terminal that is not selected as the reception target by the selection item m1 of the transmission side terminal, The gain dance information to be notified can be set for each terminal that has not been selected.
If the selection of the guidance selection item m2 is not performed after a predetermined time has elapsed after the terminal to be received is selected in the selection item m1 of the calling side terminal, predetermined guidance information set in advance is displayed. It is good also as a structure which notifies automatically.

<Variation of guidance items>
In the above embodiment, the guidance information includes a notification to connect to the answering machine service, a notification to call back a call, and a notification to request a call back. This is not a limitation.
For example, a notification for requesting a call to a landline phone or a notification for canceling the connection with the terminal on the receiving side without giving a guidance may be given, and it may be set arbitrarily. .

  Moreover, in the said embodiment, when performing the notification which requests to call again, it is good also as a structure which notifies the response possible time of the user of a receiving side terminal, for example. In this case, the response possible time is allocated to the calling terminal in the same procedure as the allocation of the response possible time when the response possible notification message is transmitted, and this response possible time is indicated in the guidance information. This may be notified, including voice information for notifying.

<Modifications of other parts>
The user's phone book information, schedule information, and priority information for each terminal managed by the customer information management database device 7 may be configured to be newly registered or updated from each terminal, or a personal computer, etc. It may be configured to be newly registered or updated from another device.
Further, in the above embodiment, a series of processes accompanying the generation of a response time notification message and guidance information accompanying a call request from the caller terminal is performed as MME3, 4, SMS / mail creation server 6, customer information management. However, the present invention is not limited to this, and the series of processes may be performed by one or more of these devices.

  It should be noted that the scope of the present invention is not limited to the illustrated and described exemplary embodiments, but includes all embodiments that provide the same effects as those intended by the present invention. Furthermore, the scope of the invention is not limited to the combinations of features of the invention defined by the claims, but can be defined by any desired combination of particular features among all the disclosed features.
