Further, when the SMS transmission / reception unit 63 receives a short message including the status notification request from the opposite mobile phone terminal output from the communication processing unit 61, the SMS transmission / reception unit 63 outputs the status notification request and the request content to the response unit 64. When the SMS transmission / reception unit 63 receives a status response command (or notification rejection command) from the response unit 64, the SMS transmission / reception unit 63 creates a short message that records the status notification response (or notification rejection response) and response information such as status information, and performs communication. Transmit to the processing unit 61.

  In response to the status notification request from the opposite mobile phone terminal, the response unit 64 inquires the permission list 53 for the phone number of the opposite mobile phone. When the telephone number is registered in the permission list 53, the response unit 64 determines that the response of the state information is permitted to the opposite mobile phone terminal of the telephone number. In this case, the response unit 64 acquires the current state of the mobile phone terminal 100 from the state storage unit 52. The response unit 64 outputs a status response command to the SMS transmission / reception unit 63 so as to respond the current status information of the mobile phone terminal 100 to the opposite mobile phone terminal of the telephone number. On the other hand, when the telephone number is not registered in the permission list 53, the response unit 64 determines that the response of the state information is rejected to the opposite mobile phone number of the telephone number. The response unit 64 outputs a notification rejection command so as to return a notification rejection response to the opposite mobile phone terminal of the telephone number.

  The above is the description of the configuration of the mobile phone terminal 100 and the mobile phone terminal 300.

  The above is the description of the configuration in this embodiment. By performing the configuration as described above, the mobile phone terminal 100 that has received the status notification request determines whether or not the response of the status information is permitted by referring to the permission list 53, and when the response is permitted.

The response unit 64B of the cellular phone terminal 300 detects the status notification request for the received short message and queries the permission list 53B. The permission list 53B notifies the response unit 64B that the mobile phone number A is not registered. The response unit 64B outputs a notification rejection command to the SMS transmission / reception unit 63B. The SMS transmission / reception unit 63B creates a short message B in which a notification rejection response is recorded. The communication processing unit 61B transmits the short message B to the mobile phone terminal 100. In this way, the mobile phone terminal 300 is informed that the mobile phone terminal 300 is in a notification refusal state in response to a status notification request from the mobile phone terminal 100 without changing the line system of the conventional mobile phone system. The telephone terminal 100 can be notified.

(Operating method when call is disabled)
Next, referring to FIG. 5, when the state is acquired from the mobile phone terminal 100 to the mobile phone terminal 300, the phone number A is registered in the permission list 53 </ b> B of the mobile phone terminal 300. A description will be given of an operation method in the case where the state of the mobile phone terminal 300 is incapable of calling, driving, or talking, that is, the user of the mobile phone terminal 300 cannot answer (call) the incoming call.

(Step S30 to Step S35)
Steps S30 to S35 are the same operation method as steps S1 to S6 described above, and thus description thereof is omitted.

(Step S36)
The response unit 64B inquires of the state storage unit 52B of the storage unit 50B about the state of the mobile phone terminal 300. The state storage unit 52B responds to the stored state in response to the state inquiry from the response unit 64B. In the present description, the state storage unit 52B stores any one of “call impossible”, “busy”, “driving” (hereinafter abbreviated as “call impossible”). . In any case, these states mean that the user of the mobile phone terminal 300 cannot respond (call) even if it receives an incoming call at this time. The response unit 64B acquires the state “call impossible” from the state storage unit 52B. The response unit 64B outputs a status response command to the SMS transmission / reception unit 63B so as to respond to the telephone number A with a status notification response of “call impossible”.

(Step S37)
The SMS transmission / reception unit 63B receives a status response command from the response unit 64B. The SMS transmission / reception unit 63B creates a short message B in which a status notification response and a status notification of the mobile phone terminal 300 “call impossible” are recorded to the telephone number A. The SMS transmitting / receiving unit 63B outputs the created short message B to the communication processing unit 61B.

(Step S38)
The communication processing unit 61B receives from the SMS transmission / reception unit 63B a short message B in which a status notification response and a status notification “call impossible” of the mobile phone terminal 300 are recorded to the telephone number A. The communication processing unit 61B transmits the short message B to the telephone number A via the wireless unit 40B.

(Step S39)
The line system 200 receives the short message B addressed to the telephone number A from the mobile phone terminal 300. The line system 200 transfers the short message B to the telephone number A in the same process as other short messages.

(Step S40)
The mobile phone terminal 100 receives the short message B addressed to the telephone number A, which is its own telephone number, from the line system 200. The communication processing unit 61A of the mobile phone terminal 100 receives, via the radio unit 40A, the short message B in which the status notification response addressed to the telephone number A and the status notification “call impossible” of the mobile phone terminal 300 are recorded. The communication processing unit 61A outputs the received short message B to the SMS transmission / reception unit 63A. The SMS transmission / reception unit 63A inputs the short message B from the communication processing unit 61A. The SMS transmitting / receiving unit 63A refers to the status notification response recorded in the short message B, and detects that the short message B is a status notification response from another mobile phone terminal. The SMS transmitting / receiving unit 63A outputs the status notification response and the status notification “call impossible” of the mobile phone terminal 300 recorded in the short message B to the information acquisition unit 62A. The information acquisition unit 62A inputs the status notification response and the status notification “call impossible” of the mobile phone terminal 300 from the SMS transmission / reception unit 63A. The information acquisition unit 62A outputs the state notification “call impossible” of the mobile phone number 300 to the display unit 20A.

(Step S41)
The information acquisition unit 62A outputs “necessity of state change notification” to the display unit 20A. This is because the mobile phone terminal 300 is currently in a “call impossible” state, but when the mobile phone terminal 300 changes to a “call available” state thereafter, the user can select whether to receive a notification. It means that. Whether or not the state change notification is necessary is output, for example, to the LCD of the display unit 20A, such as “Do you want to be notified when the state of the mobile phone terminal 300 becomes callable?”. The user may select and input “Yes” or “No” for this question. Alternatively, an operation method in which whether or not state change notification is necessary is registered in advance and stored in the state state acquisition unit 62A is also possible. In this case, there is no need to select the user, and the process automatically proceeds to the next operation. Regardless of the operation method, if the user selects “No” for “Necessity of state change notification”, that is, if the user selects not to receive a state change notification, the operation is completed in this step. It becomes.
On the other hand, if the user selects “Yes” for “necessity of state change notification”, that is, if the user selects to receive a state change notification, the process proceeds to the following operation.
In this case, the information acquisition unit 62A outputs a state change notification acquisition command to the SMS transmission / reception unit 63A. The SMS transmission / reception unit 63A inputs a state change notification acquisition command from the information acquisition unit 62A. The SMS transmitting / receiving unit 63A creates a short message A in which the state change notification request and the telephone number A of the portable information terminal 100 are recorded to the telephone number B. The SMS transmitting / receiving unit 63A outputs the created short message A to the communication processing unit 61A.

(Step S42)
The communication processing unit 61A inputs the short message A output by the SMS transmission / reception unit 63A. The communication processing unit 61A transmits the short message A to the telephone number B via the radio unit 40A.

(Step S43)
The line system 200 receives the short message A addressed to the telephone number B from the mobile phone terminal 100. The line system 200 transfers the short message A to the telephone number B in the same process as other short messages.

(Step S44)
The mobile phone terminal 300 receives the short message A addressed to the phone number B, which is its own phone number, from the line system 200. The communication processing unit 61B of the mobile phone terminal 300 receives, via the wireless unit 40B, the state change notification request addressed to the telephone number B and the short message A in which the telephone number A is recorded. The communication processing unit 61B outputs the received short message A to the SMS transmission / reception unit 63B. The SMS transmitting / receiving unit 63B inputs the short message A from the communication processing unit 61B. The SMS transmitting / receiving unit 63B refers to the state change notification request recorded in the short message A to detect that the short message A is a state change notification request from another mobile phone terminal. The SMS transmitting / receiving unit 63B outputs the state change notification request and the telephone number A recorded in the short message A to the response unit 64B. The response unit 64B inputs the state change notification request and the telephone number A from the SMS transmission / reception unit 63B. The response unit 64B detects the state change notification request from the telephone number A. The response unit 64B inquires whether the telephone number A is registered in the permission list 53B of the storage unit 50B. The permission list 53B searches whether the telephone number A is registered in the permission list 53B in response to an inquiry from the response unit 64B. In this description, the telephone number A is registered in the permission list 53B. The permission list 53B detects the telephone number A. The permission list 53B notifies the response unit 64B that the telephone number A is registered. The response unit 64B detects that the telephone number B is registered in the permission list 53B, and determines that a state change notification response can be transmitted to the mobile phone terminal 100 having the telephone number A. When the response unit 64B determines that the state change notification response can be transmitted to the telephone number A, the response unit 64B stores the state change notification request from the telephone number A.
Thereafter, the response unit 64B periodically inquires of the state storage unit 52B of the storage unit 50B about the state of the mobile phone terminal 300. This inquiry may be made periodically in time, or may be inquired every time the control unit 60B updates the state storage to the state storage unit 52.

(Step S45)
The state of the mobile phone terminal 300 changes from “call impossible” to “call possible”.

(Step S46)
The state storage unit 52B responds to the stored state in response to the state inquiry from the response unit 64B. The state storage unit 52B responds with the stored state “call possible”. The response unit 64B acquires the state “call possible” from the state storage unit 52B. The response unit 64B detects that the state of the state storage unit 52B has changed. The response unit 64B outputs a status change notification response command to the SMS transmission / reception unit 63B so as to respond to the telephone number A with a status change response of “call possible”. The SMS transmission / reception unit 63B inputs a state change notification response command from the response unit 64B. The SMS transmission / reception unit 63B creates a short message B in which the state change notification response and the state notification “call possible” of the mobile phone terminal 300 are recorded to the telephone number A. The SMS transmitting / receiving unit 63B outputs the created short message B to the communication processing unit 61B.

(Step S47)
The communication processing unit 61B receives from the SMS transmission / reception unit 63B the short message B in which the state change notification response and the state notification “call available” of the mobile phone terminal 300 are recorded to the telephone number A. The communication processing unit 61B transmits the short message B to the telephone number A via the wireless unit 40B.

(Step S48)
The line system 200 receives the short message B addressed to the telephone number A from the mobile phone terminal 300. The line system 200 transfers the short message B to the telephone number A in the same process as other short messages.

(Step S49)
The mobile phone terminal 100 receives the short message B addressed to the telephone number A, which is its own telephone number, from the line system 200. The communication processing unit 61A of the mobile phone terminal 100 receives, via the radio unit 40A, the status change notification response addressed to the telephone number A and the short message B in which the status notification of the mobile phone terminal 300 is recorded “call possible”. The communication processing unit 61A outputs the received short message B to the SMS transmission / reception unit 63A. The SMS transmission / reception unit 63A inputs the short message B from the communication processing unit 61A. The SMS transmitting / receiving unit 63A refers to the state change notification response recorded in the short message B to detect that the short message B is a state change notification response from another mobile phone terminal. The SMS transmission / reception unit 63A outputs the status change notification response and the status notification “call available” recorded in the short message B to the information acquisition unit 62A. The information acquisition unit 62A inputs the state change notification response and the state notification “call possible” of the mobile phone terminal 300 from the SMS transmission / reception unit 63A. The information acquisition unit 62A outputs the status notification “callable” of the mobile phone number B to the display unit 20A.

The above is the case where the state is acquired from the mobile phone terminal 100 to the mobile phone terminal 300, and the telephone number A is registered in the permission list 53B of the mobile phone terminal 300, but the state of the mobile phone terminal 300 is not callable. A description will be given of an operation method in a case where the user is driving or talking, that is, when the user of the mobile phone terminal 300 cannot respond to the incoming call (call).
When the state of the mobile phone terminal 300 is “impossible to call”, the response unit 64B periodically makes a state inquiry to the state storage unit 52B in response to a state change notification request from the mobile phone terminal 100. The response unit 64B detects that the state of the mobile phone terminal 300 recorded in the state storage unit 52B has changed, and outputs a state change notification response command. The SMS transmitting / receiving unit 63B creates a short message B in which a state change notification response is recorded for the telephone number A. The communication processing unit 61B transmits the short message B to the mobile phone terminal 100.
By doing in this way, the mobile phone terminal 100 does not change the line system 200. Even when the mobile phone terminal 300 receives a status notification once, even if the mobile phone terminal 300 is “call impossible”, then, It is possible to detect that the state has changed to “call possible”.
Note that, when the mobile phone terminal 300 receives a status change notification request, the mobile phone terminal 300 may be configured to respond with a status change notification response only when the status information indicates “call possible”. In addition, in the state change notification request, it may be an operation method for designating which state is to be responded when the state is entered.

(How to operate out of service)
Next, using FIG. 6, an operation method when the mobile phone terminal 100 is “out of service area” when the state acquisition is performed from the mobile phone terminal 100 to the mobile phone terminal 300 will be described.

(Step S50 to Step S52)
Steps S50 to S52 are the same as steps S1 to S3, and a description thereof will be omitted.

(Step S53)
The line system 200 receives the short message A addressed to the telephone number B from the mobile phone terminal 100. The line system 200 transfers the short message A to the telephone number B in the same process as other short messages. However, since the mobile phone terminal 300 is in the “out of service” state, it cannot receive the short message A.

(Step S54)
The line system 200 detects that the mobile phone terminal 300 is out of range. In this case, the line system 200 transmits an SMS out-of-service response of the short message A to the mobile phone terminal 100 as a short message A transfer failure notification (Failure Report). The operation method in which the line system 200 detects that the mobile phone terminal 100 is out of the service area and the operation method in which the transfer failure notification is transmitted to the mobile phone terminal 100 are based on known techniques, and thus description thereof is omitted.

(Step S55)
The communication processing unit 61A of the mobile phone terminal 100 inputs the SMS out-of-service response of the short message A from the line system 200 via the wireless unit 40. The communication processing unit 61A notifies the information acquisition unit 62A of the SMS out-of-service response of the short message A. The information acquisition unit 62A inputs an SMS out-of-service response and detects that the short message A cannot be received because the mobile phone terminal 300 is out of service. The information acquisition unit 62A outputs to the display unit 20A that the mobile phone terminal 300 is in the “out of service” state.
Thereafter, the information acquisition unit 62A stores the telephone number B of the mobile phone terminal 300 and periodically outputs a status acquisition command of the mobile phone terminal 300, so that the mobile phone terminal 300 returns to the area. It may be detected that the “out of service” state is lost. In this case, the operations from step S50 to step S53 may be repeated periodically. For example, when the mobile phone terminal 300 changes from the “out of service” state to the “callable” state, the operation is the same as the operation from step S1 to step S11.

  The above is the description of the operation method when the mobile phone terminal 300 is in the “out of service area” in the case where the state is acquired from the mobile phone terminal 100 to the mobile phone terminal 300. The mobile phone terminal 100 detects that the mobile phone terminal 300 is in the “out of service” state by detecting the transfer impossibility notification from the line system 200, so that the mobile phone terminal 100 does not change the line system 200. The state of the terminal 300 can be acquired.

  Note that the mobile phone terminal 100 receives the transfer impossible notification from the line system 200 and detects that the mobile phone terminal 300 is in the “out of service” state. This may be an operation method in which a time-out is detected by measuring a certain time after the short message A is transmitted, and the mobile phone terminal 300 is determined to be “out of service area”.

  The above is the description of the operation method in this embodiment.

As described above, according to the present invention, the state of the mobile phone terminal on the opposite side can be changed before making a call to the mobile phone number selected by the user on the outgoing side without changing the line system 200. It can be acquired.
It should be noted that the configuration and operation method described above can be omitted, replaced by other methods, or have functions that can be further applied with functions. Such an example is described below.

  First, the method of notifying the user of the status notification acquired by the information acquisition unit 62 is output to the display unit 20 in the above description. This is realized by displaying the received short message on the display unit 20. It can also be realized by several other methods. For example, a method of generating a sound such as a ring tone from the voice input / output unit 10, a method of flashing an LED when the mobile phone terminal 100 is equipped with an LED (Light Emitting Diode), etc. A method of displaying can be considered. Or you may output these simultaneously.

  Alternatively, a message such as a sentence or a voice registered in advance by the user of the mobile phone terminal 300 may be recorded and responded simultaneously to the short message B that records the status response notification. When the mobile phone terminal 100 receives the short message B, the mobile phone terminal 100 outputs the message recorded in the short message B to the display unit 20A and the voice input / output unit 10A. For example, when the mobile phone terminal 300 returns a status notification of “Driving”, a message such as text data or voice data such as “Driving from Tokyo to Shimoda. Record and respond to. The user of the mobile phone terminal 100 knows the current state of the user of the mobile phone terminal 300 more specifically by checking the message recorded in the short message B on the display unit 20A or the voice input / output unit 10A. It becomes possible. In addition, the user of the mobile phone terminal 100 becomes a reference for selecting the state change notification.

  Further, when the mobile phone terminal 300 includes a GPS antenna for acquiring position information, the position information data may be recorded and responded to in a short message of a status notification response. Accordingly, the mobile phone terminal 100 can display the position information data in association with the map. In this way, the user of the mobile phone terminal 100 can know the current status of the user of the mobile phone terminal 300 in more detail based on the map information.

  Next, regarding the information stored in the permission list 53 and the information inquired by the response unit 64, in the above description, the response unit 64 inquires whether a telephone number is described in the permission list 53. This may be further classified by adding a flag to the telephone numbers described in the permission list 53. For example, among the telephone numbers described in the permission list 53, a response from a flagged telephone number is attached with the above-described location information, or the permission list 53 includes a telephone number storage unit. A method of responding to a phone number stored in the phone book stored in 51, a method of returning a response only to a specific person with a flag among the phone numbers stored in the phone book, etc. Can be considered.

  Further, in the status notification request (or status notification response) and the permission list 53, the identification is performed based on the telephone number, but this may be identified by an identification number unique to the mobile phone terminal or the like.

  In this embodiment, SMS is a communication bearer, but this is not limited to SMS. The present invention can be realized as long as the same data can be transmitted and received through the line system 200.

  In addition, each notification and response in the above description is when SMS is used, and when charging is involved, before sending each notification and response, the user is notified that the user will be charged by pop-up etc. It is also possible to ask for permission.

  Finally, in this embodiment, the mobile phone terminal 100 is set as the calling side, and the mobile phone terminal 300 is set as the receiving side. Needless to say, this is the mobile phone terminal 300 as the calling side and the mobile phone terminal 100 as the receiving side. It is the same. In addition, the present invention can process without problem by the response unit 64 performing processing with a time difference even when a status notification request is simultaneously sent from a plurality of mobile phone terminals to one mobile phone terminal. Is possible.
