Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile terminal exchanging system, and more particularly to a mobile terminal exchanging system including a battery-operated mobile terminal and an exchange capable of setting an incoming call waiting state and the like.

[0002]

2. Description of the Related Art Conventionally, in a mobile terminal such as a mobile phone, a "call mode" for making a call similar to a normal general subscriber telephone, an incoming call for receiving an incoming call from another mobile terminal or a general subscriber telephone. It has various operation modes such as a "standby mode" which is a standby state (hereinafter also referred to as a standby state), a "disconnect mode" in which power is cut off and neither outgoing call nor incoming call can be made. Of these, in the "standby mode", power is supplied only to the circuits required for incoming calls to save power. The reason why various operation modes are provided in this way is that a mobile terminal such as a mobile phone is generally driven by using a battery such as a nickel-cadmium battery, and it is necessary to prevent battery consumption as much as possible. .

[0003]

However, when the "standby mode" is set, the mobile phone supplies power only to the circuits necessary for receiving an incoming call, so the battery is saved but consumed. ing. On the other hand, when the user wants to receive an incoming call, the user sets it in the "standby mode",
I often forget to set "standby mode". At this time, the battery may be exhausted because it is left in the "standby mode", and it may not be possible to make a call when necessary.

In order to prevent the battery from being consumed as much as possible, the user may turn off the power each time he or she thinks that the user will not use the battery, but this may not allow him to receive an important call. Also, to prevent the battery from running down, it is a heavy burden on the user to frequently turn the power off and on, and repeatedly set the "standby mode", which may cause setting errors.

The present invention has been made in consideration of the above circumstances, and when the user is requested to wait for an incoming call, the user can put the mobile terminal in the "standby mode", and Efficient management of incoming call waiting, with the purpose of efficiently notifying the mobile terminal that there was an invalid call when the terminal is not in "standby mode" after setting "standby mode" And to prevent the drain of the battery of the mobile terminal.

FIG. 10 shows a basic block diagram of the present invention. According to the present invention, in a mobile terminal switching system including a mobile terminal that can be in an incoming call waiting state that enables an incoming call and an exchange that exchanges a call between the mobile terminals, any mobile terminal puts itself in an incoming call waiting state. The standby time notifying unit 1 for notifying the exchange of the standby time and the standby request time desired to be in the standby state for receiving an incoming call to another mobile terminal, and the exchange notifies the standby time and the standby request time. The present invention provides a mobile terminal exchange system characterized by comprising an information storage unit 6 for storing the information.

When the standby time for a specific mobile terminal is stored in the information storage unit 6 of the exchange, when the communication between the mobile terminal and the exchange is performed, the exchange is switched. Provides the mobile terminal exchange system with the standby request time to the mobile terminal. Here, the exchange may notify the mobile terminal of a standby request time for the mobile terminal by voice.

Further, the mobile terminal has a standby time setting unit 3, and this standby time setting unit 3 sets a time corresponding to the standby request time notified from the exchange as a standby time. The incoming call waiting state may be set only during the standby time.

Further, according to the present invention, the mobile terminal further has a message notification unit 2 for notifying predetermined information to the exchange, and the exchange further stores the message information storage unit 4 for storing the notified message information. And an information notifying unit 5 for notifying the corresponding mobile terminal of this message information at a predetermined timing.

Here, when message information for the mobile terminal is stored in the message information storage unit 4 of the exchange while the standby time of the mobile terminal is stored in the information storage unit 6 of the exchange. The information notifying unit 5 may notify the mobile terminal of the message information for the mobile terminal when the current time is within the standby time of the self.

Further, when message information for the mobile terminal is stored in the message information storage unit 4 of the exchange when the self-standby time of the mobile terminal is not stored in the information storage unit 6 of the exchange, a predetermined value is set. The information notifying unit 5 may notify the mobile terminal of the message information for this mobile terminal periodically or at random time intervals.

Further, when an arbitrary mobile terminal A tries to call the mobile terminal B but does not respond, a voice message corresponding to the fact that the mobile terminal B has not responded from the exchange to the mobile terminal B. May be notified.

As described above, the mobile terminal switching system of the present invention is composed of the mobile terminal and the exchange. However, the so-called communication control such as call origination / reception, telephone communication, data transmission / reception between the mobile terminal and the exchange is not performed. Generally, since it is performed wirelessly, both the mobile terminal and the exchange are equipped with hardware that executes a wireless communication function. In addition to a mobile terminal, a general subscriber telephone using a cable may be connected to the exchange.

The standby time notification unit 1, the message notification unit 2, and the standby time setting unit 3 of the mobile terminal can be realized by a so-called microcomputer and its peripheral circuits. The microcomputer includes a ROM, a RAM, a timer, an I / O controller and the like, and a program for executing the standby time notification function and the standby time setting function is stored in the RAM or the ROM. The peripheral circuit is composed of a communication controller for transmitting data and voice, a call circuit, and the like.

Here, the standby time, standby request time and message information input to the exchange are input directly from an input device such as a ten-key pad or correspond to message information stored in advance in a RAM or the like. The number may be entered.

Both the standby time and the standby request time are preferably represented by the time when the mobile terminal should start the incoming call standby state and the time when the mobile terminal should end the standby state. It may be expressed by width. Further, when the mobile terminal sets its own standby time or when the mobile terminal is notified of the standby request time from the exchange, the standby time setting unit 3 uses that time as the standby time, such as a RAM. However, when the present time reaches the set standby time, the mobile terminal drives at least the circuit necessary for waiting for an incoming call. The circuit necessary for waiting for an incoming call is, for example, a microcomputer or a communication controller.

The exchange has a message information storage unit 4 and an information storage unit 6, which can be constituted by a storage device such as a RAM or a hard disk. Further, although the exchange has a function of notifying the mobile terminal of the standby request time, the standby request time may be notified as data or may be notified as voice to the user of the mobile terminal. When notifying as data, a so-called microcomputer and a communication controller are provided in the exchange, and when notifying as voice, a memory such as RAM is further provided, and a voice message to be some template is provided in advance. May be stored.

Further, the exchange has an information notifying unit 5 for notifying the mobile terminal of the message information, which can also be realized by a microcomputer or a communication controller. The message information notified from the exchange to the mobile terminal may be data or voice. Further, the message information may be predetermined data or voice stored in the ROM or the like, or may be data or voice input from the input device.

The information notifying unit 5 of the exchange preferably has a timer in order to notify the mobile terminal of the message information at a predetermined timing. Here, the predetermined timing may be a time preset in the ROM, the RAM, or the like, a periodic time at predetermined time intervals, or a random time interval. The "set time" means, for example, 10 o'clock every day. "Periodic at predetermined time intervals" means, for example, repeating notifications indefinitely every 1 minute, or repeating notifications 10 times every 10 minutes. The "random time interval" is, for example,
This means that notification is given 10 times at any time within one hour.

When the standby time of the mobile terminal which notifies the message information is set in the exchange, the predetermined timing means after the current time reaches the standby time, and the standby time Message information is notified after the time is reached.

As described above, according to the present invention, the mobile terminal notifies the exchange of the standby time of its own mobile terminal, and the exchange stores the standby time.
It is possible to centrally manage the incoming call waiting states of all the accommodated mobile terminals. Further, since it is possible to notify the time (standby request time) that a certain mobile terminal A wants to be in the incoming call waiting state to the mobile terminal A via the exchange,
By setting the mobile terminal A in the incoming call waiting state for the standby request time, the incoming call waiting can be effectively managed, and the consumption of the battery can be further reduced.

Further, since the mobile terminal sets the time corresponding to the standby request time as its own standby time and makes the incoming call waiting state only during the standby time, the user voluntarily Even if you have not set the standby time, it automatically enters the waiting state for incoming calls only for the required time, so you can manage incoming calls effectively and prevent battery drain due to forgetting to cancel the waiting state. .

Further, according to the present invention, since the standby request time is notified by voice, it is important that the notified user of the mobile terminal sets the standby time so as to include the requested standby time. It is possible to manage effective incoming calls and prevent battery consumption without invalidating various incoming calls.

Furthermore, according to the present invention, the exchange notifies the mobile terminal corresponding to the message information notified from the mobile terminal at a predetermined timing, so that the mobile terminal can be used in the exchange. It is possible to effectively manage the calling operation and notification of message information. That is, it is possible to reduce useless call-out operations from the exchange to the mobile terminal, and thus to improve the line utilization efficiency.

Further, since a voice message corresponding to the fact that a mobile terminal B is not responding from any mobile terminal A via the exchange is notified to the mobile terminal B, this voice message is sent. The received user of the mobile terminal B can immediately make a response call to the mobile terminal A.

Next, the outline of the operation of the standby time management unit when the information requesting the setting of the standby time is transmitted from the mobile terminal A to the exchange will be described with reference to FIG. First, when a call is made from the mobile terminal A, the transceiver unit C1 of the exchange.
Reference numeral 6 designates the telephone number of the mobile terminal A and the calling party telephone number memory C.
13 is stored. In the information transmitted from the mobile terminal A, the designated code = “3”, the filling parameter = “start:
It is assumed that the destination telephone number is inserted at 10:00, end: 12:20 ". Here, the ten-key information analysis unit C14 analyzes the information and the corresponding memories (C10, C11, C12). ) To.

Standby time message sentence template editing section C5
From the read template and the parameters stored in the message filling parameter memory C11 = “start: 10:00, end = 12: 20”, “the standby time is 10:00 to 12:20. Message is created. After this, the message text created in the standby time message storage unit C6, the telephone number stored in the destination telephone number memory C12, and the calling mobile terminal A stored in the calling telephone number memory C13. Phone number 1
Remember as a set. The above is the operation of storing the standby request time in the exchange.

After that, when a call is made from the mobile terminal B having the same number as the destination telephone number stored together with the message text stored in the standby time message storage unit, the stored message is displayed. The sentence is read out and notified to the mobile terminal B by voice. That is, when the mobile terminal B makes a call, the telephone number of the mobile terminal B is stored in the caller telephone number memory C13.

The designated standby time message extraction section C7 is a destination telephone number stored as a pair with the message text stored in the standby time message storage section C6, and a calling party telephone number memory C13. When it is judged that they match with each other, the message text is read out and given to the voice synthesizing section C9. For example,
When the destination telephone number corresponding to the message sentence "standby time is 10:00 to 12:20" matches the mobile terminal B, this message sentence is given to the voice synthesizing unit C9.

The voice synthesis unit C9 reads out a phoneme corresponding to the message sentence from the phoneme 8 and performs voice synthesis, and notifies the mobile terminal B by voice of this message sentence through the transmitter unit C15 and the transmitter / receiver unit C16. Here, the standby time message registration unit C2, the basic standby time message sentence template storage unit C3, the standby time message sentence template extraction unit C4, the standby time message sentence template editing unit C5, the designated standby time message The extraction subject C7 and the numeric keypad information analysis unit C14 are generally operated by a microcomputer,
The operation of each unit is performed according to the program stored in M or the like.

FIG. 3 shows an embodiment of the sequence for setting and registering the standby request time in the mobile terminal switching system of the present invention. As an initial state, it is assumed that the called mobile terminal B is in the non-standby state. That is,
It is assumed that an incoming call cannot be received because the power is cut off due to the battery being cut off.

At this time, when the calling operation of the mobile terminal B is performed from the mobile terminal A (S1), since the mobile terminal B does not respond, the user of the mobile terminal A waits for an incoming call to the mobile terminal B. The desired time, that is, the standby request time and the message code number are registered by a predetermined operation using the ten keys (S2). This registration information is transferred to the exchange and stored in the memory inside the exchange as described above (S3).

After that, it is assumed that the user turns on the mobile terminal B (S4). At this time, a call is made to inquire as to whether or not the standby request time of the user is registered to the exchange automatically by the operation of the user or by turning on the power (S).
4). Since this calling is different from the purpose of ordinary communication with other mobile terminals, for example, a predetermined special number may be dialed.

The exchange, which has received the special call from the mobile terminal B, confirms whether or not the standby request time for the mobile terminal B is registered (S5). If registered, the mobile terminal B is notified of the message text (see FIG. 2) including the standby request time by voice as described above. The user of the mobile terminal B who has received the notification of the message message by voice sets the standby time in response to the message message (S6). When the standby time is set, the mobile terminal B may continue the power-on state if the time includes the current time, but the set standby time does not include the current time. If so, turn off the power automatically. In this way, it is possible to effectively prevent battery consumption.

After the power is turned off to enter the non-standby state,
When the set standby time comes, mobile terminal B automatically enters the standby state (S7). Therefore, power is supplied to the circuit portion required for the standby state, and the incoming call is ready. After that, if the operation of calling the mobile terminal B from the mobile terminal A is performed (S8), the mobile terminal B can accept the incoming call, and the conversation between the mobile terminals A and B can be performed. When the end time of the set standby time comes, mobile terminal B automatically cancels the standby state and enters the non-standby state (S9).

As described above, since the standby state of the mobile terminal B is set based on the standby time setting request from the other mobile terminal A, the battery of the user of the mobile terminal B is set. It is possible to reduce the management load due to exhaustion, and it is possible to effectively manage incoming calls and prevent battery consumption.

Also, in this embodiment, the exchange C notifies the mobile terminal B of the standby request time from the mobile terminal A by voice, and the user of the mobile terminal B who hears this voice requests the standby time. I set it as my standby time,
The exchange may notify the standby request time in the data format to the mobile terminal B, and the microcomputer in the mobile terminal B may automatically set the standby request time in this data format as its own standby time. . If you do this, the incoming call waiting state is automatically set only for the time required to receive the incoming call.
It is possible to prevent the user from forgetting to set the standby time and setting errors, and manage incoming calls effectively.

Further, it is possible to prevent the battery from being consumed due to the user forgetting to cancel the incoming call waiting state. The fact that the exchange C notifies the mobile terminal B of the standby request time in the data format can be easily realized by the microcomputer and the communication controller in the exchange. Also, the mobile terminal B
In addition, a stand-by time setting unit for setting the stand-by request time notified in the data format as the self-standby time may be provided, and the function of this part is also easy by incorporating a microcomputer and necessary programs. Can be realized.

Embodiment 2 Here, in the mobile terminal switching system of the present invention,
An example of performing notification management of a message corresponding to a standby state will be described. FIG. 4 is a block diagram showing the configuration of the part of the standby time management unit of the exchange according to the second embodiment.

In FIG. 4, the "power off" storage unit C21
Is a memory for storing that a certain mobile terminal k is in a "power-off" state, that is, not in a standby state. Whether the mobile terminal k is in the "power off" state
The other party's power failure detection unit C28 performs this. When a call is made from another mobile terminal m to the mobile terminal k, the exchange C calls the mobile terminal k. However, when there is no response from the mobile terminal k for a certain period of time, the exchange C determines that the mobile terminal k is It can be determined that the power is off. That is, the exchange C
When the other party's power-off detection unit C28 detects that the call to a certain mobile terminal k has ended abnormally, it notifies the "power-off" message sending unit C27 that the mobile terminal k is powered off. Further, it is stored in the “power off” storage unit C21.

Here, the "power off" message sending section C2
Reference numeral 7 is a part for notifying a message to the effect that "the mobile terminal k is not in the standby state" to the mobile terminal m which is the originator of the call origination operation to the mobile terminal k. The recording timing generation unit C26 uses the "power cut" message transmission unit C27.
In response to a request from the mobile terminal m, the recording operation of the voice message sent from the mobile terminal m thereafter is started and stopped.

The recording of this voice message is based on the timing sent from the recording timing generator C26.
The message recording unit C22 performs this. The voice message is stored in the memory in the message recording unit C22. The receiving section C29 performs A / D conversion on the voice message sent through the transmitting / receiving section C16, and the message recording section C22.
To give to.

The ten-key information input section C30 receives information such as the standby time of the mobile terminal itself sent from the mobile terminal. The standby time itself received here is stored in the standby time storage unit C23, and information such as "the standby time is stored" is stored in the standby information storage unit C3.
1 is stored. The clock unit C33 is a so-called timer and counts the current time, the elapsed time from the set time, and the like.

The standby time determination section C24 determines whether or not information indicating that "standby time is stored" is stored in the standby information storage section C31, and the current time is the standby time. It is to determine whether or not the standby time stored in the storage unit C23 has come. Message extractor C
Reference numeral 25 is a portion for reading the voice message stored in the message recording unit C22 in response to the activation request from the standby time determination unit C24. Further, the read voice message is notified to the corresponding mobile terminal through the transmission / reception unit C16. The above is the standby time management unit of the exchange C.
This is the configuration of the part that manages the notification of messages corresponding to the standby state, but the operation of these parts is usually controlled by a microcomputer.

Next, when a call is made from the mobile terminal A to the mobile terminal B, but the call is interrupted, the sequence for notifying the mobile terminal B of the voice message from the mobile terminal A is the exchange C. The case where the standby time of the mobile terminal B is stored and the case where it is not stored will be described separately.

FIG. 5 shows an embodiment of the sequence when the standby time of the mobile terminal B is stored in the exchange C. Here, first, the user of the mobile terminal B performs an operation such as inputting a ten-key pad to register its own standby time (S1).
1). That is, the user of the mobile terminal B turns on the power,
The start time and end time of the standby time or the time width is input by a predetermined operation. After this input is completed, the mobile terminal B
A special number dial for standby time registration is used to communicate with the exchange C to request registration of the standby time.

The exchange C stores the standby time sent from the mobile terminal B in the standby time storage section C23 as that of the mobile terminal B through the ten-key information input section C30. For example, "mobile terminal B", standby start time, and standby end time are stored. At the same time, the ten-key information input unit C30 stores in the information standby information storage unit C31 indicating that the standby time of the mobile terminal B has been stored. For example, the memory area corresponding to mobile terminal B is flagged.
With the above operation, the standby time of the mobile terminal B is registered in the mobile terminal B itself and the exchange C (S1).
2).

After the completion of the registration, the user of the mobile terminal B may turn off the power to save the battery if the current standby time is not reached. Alternatively, the microcomputer inside the mobile terminal B may automatically shift to a power-saving state rather than a standby state when the current standby time is not reached. In this way, it is possible to reduce battery consumption due to forgetting to turn off the power.

Next, it is assumed that there is a call from the mobile terminal A to the mobile terminal B when the mobile terminal B is powered off and in the non-standby state (S13). At this time, the exchange C calls the mobile terminal B, but since there is no response from the mobile terminal B, the exchange C detects that the mobile terminal B is in the power-off state. As described above, this detection operation is performed by the other party's power failure detection section C28 and activates the "power failure" message sending section C27.

After that, the "power off" message sending section C2
7 stores in the "power-off" storage unit C21 that the mobile terminal B is in the "power-off" state, and says "The mobile terminal B is in the power-off state. If there is a message to the mobile terminal B, talk later. Mobile terminal A
To the recording timing generator C26
Start.

After listening to the message from the exchange C, the user of the mobile terminal A speaks the message to the mobile terminal B (S14). This message is received by the receiver C2 of the exchange C.
It is recorded in the message recording section C22 through 9 (S1
5). Further, the recorded message is given an identifier indicating that it is for the mobile terminal B.

In the exchange C, the standby time determination unit C24
Always confirms that the standby information storage unit C31 stores information indicating that the standby time is stored.
Since it is currently determined that the standby information storage unit C31 stores the information that "the standby time of the mobile terminal B is stored", the standby time determination unit C24 determines the standby time. The standby time of the mobile terminal B stored in the storage unit C23 is read out, and the standby time of the mobile terminal B is compared with the current time read out from the clock unit C33.

At this time, if it is confirmed that the current time is within the standby time of the mobile terminal B, the exchange C calls the mobile terminal B (S17). On the other hand, mobile terminal B
Also in the above, the microcomputer always confirms whether or not the present time reaches the standby time set by itself, and when the standby time comes, the microcomputer automatically enters the standby state (S16). That is, in the mobile terminal B, power is supplied to the circuits necessary for receiving an incoming call because the mobile terminal B enters the incoming call waiting state. Therefore, the mobile terminal B should surely respond to the incoming call of the mobile terminal B made by the exchange C.

After the mobile terminal B responds to this call, the exchange C notifies the mobile terminal B of the voice message from the mobile terminal A stored in the message recording section C22 (S17). Here, whether or not the mobile terminal B responds may be performed by an incoming call detection function, which is a basic function of the exchange C, which is not shown in FIG. 4, and the fact that the mobile terminal B responded is determined by the standby time determination. The section C24 is notified.

Further, the standby time determination section C24 gives an instruction to the message extraction section C25 to read a recorded message for the mobile terminal B, a desired recorded message is read from the message recording section C22, and further, it is passed through the transmission / reception section C16. The mobile terminal B is notified. Further, not only the recorded voice but also the telephone number of the mobile terminal A may be added to the notified message.

As described above, when the standby time of the mobile terminal B is stored in the exchange, when a message from another mobile terminal A is registered, the current time is that of the mobile terminal B. Since the call operation of the mobile terminal B is performed after the standby time is reached, it is possible to prevent unnecessary call operation from the exchange and improve the line use efficiency of the exchange.

Further, the exchange can centrally manage the incoming call waiting states of all mobile terminals. Also, the mobile terminal B
For those of you who are not in the stand-by state, you will be notified of the voice message from the destination that was cut off in the stand-by state, so you can manage effective incoming calls without invalidating important incoming calls. . Further, since the mobile terminal automatically moves to the standby state and is released, it is possible to effectively prevent the consumption of the battery.

Next, FIG. 6 shows an example of the sequence in the case where the standby time of the mobile terminal B is not stored in the exchange C. In the figure, each operation of calling mobile terminal B by mobile terminal A (S21), no response from mobile terminal B, registering a message to mobile terminal B (S22), and storing the message in the exchange (S23) Is the same as that shown in FIG. 5, and therefore its explanation is omitted here.

The embodiment shown in FIG. 6 differs from the embodiment shown in FIG. 5 in the timing of calling the mobile terminal B. That is, when the standby time of the mobile terminal B is stored in the exchange C, the operation of calling the mobile terminal B is started when the current time falls within the standby time. In the embodiment, the storage of the message to the mobile terminal B (S2
3) After the end, the point that the mobile terminal B is called at random timing or regular timing is different.

Here, the random time interval may be, for example, 10 times of calling at any time of one hour, or may be called at any time interval without limitation. Further, the calling operation may be performed periodically such that the calling is performed 10 times every 10 minutes or every hour on an hourly basis.

In storing the message in the mobile terminal B shown in FIG. 6 (S23), the voice message is stored in the message recording section C22. After this, the standby time determination unit C2
4 recognizes that the message recording unit C22 stores the message to the mobile terminal B, and further, the standby information storage unit C31 indicates that "the standby time of the mobile terminal B is stored". When it is detected that the information is not stored, a random number is generated and the time for calling the mobile terminal B is determined. Then, the exchange C continues the calling operation at random time intervals until the mobile terminal B responds to the incoming call (S24).

When the mobile terminal B is called after the standby state (S25), the mobile terminal B responds to the incoming call, but the voice message from the mobile terminal A is moved as in S17 of FIG. Notify the terminal B (S26).

As described above, when the standby time of the mobile terminal B is not stored in the exchange C, the exchange C does not know whether or not the mobile terminal B is in the standby state. By making a call to the terminal at random timing, the retained voice message can be promptly notified after the mobile terminal B enters the standby state.

If the mobile terminal B automatically calls the exchange C after the mobile terminal B is set to the standby state, the message to the mobile terminal B as shown in S23 will be sent to the exchange C. Can be notified to the mobile terminal B more promptly.

As described above, in the mobile terminal, the standby time is set by the user or automatically.
For example, a mode that does not receive incoming calls (non-standby state), a mode that continuously waits for incoming calls (continuous standby state), a mode that waits for incoming calls only during a designated time period (time designation), and a random or fixed Various modes such as a mode (cycle) of waiting for incoming call at a cycle may be set.

Further, a standby time management mode for setting each of the above modes and a call mode for enabling a normal call may be provided. These mode settings may be set by providing a mode selector switch on each mobile terminal, or may be set by a predetermined operation using a ten-key pad or the like. In addition, necessary parameters are input using a ten-key pad or the like for each mode. Here, the necessary parameter is, for example, a time zone to be set in the case of the time setting mode.

FIG. 7 shows a flowchart of an example of mode setting in the mobile terminal. The user sets the mode selector switch to the standby time management mode (S31). Here, the "current setting mode" and "current standby time" in the mobile terminal are displayed on the LCD or the like, and these settings can be changed (1
#) Or no (0 #) is input (S32).

When No (0 #) is input, the standby time management state is entered, and if the standby time is not currently set, the power is turned off (S38). In S32, when yes (1 #) is input, "standby time designation" or "cycle designation" is displayed, and the time designation (0 #) or cycle designation (1 #) is waited for input ( S33).

Here, when the user inputs the time designation (0 #), the standby time is next input (S34). For example, as shown in FIG. 7, when "9:15 to 17:30" is the standby time, "# 0915 * 1730"
Enter #. Next, if the input is correct, no (0 #)
When is input, the standby time management state is set (S38). Further, when the resetting is to be performed again for correction of the input, etc., if yes (1 #) is input (S36), the process returns to S34.

In S33, when the cycle designation (1 #) is input, the user inputs the standby time, but here, for example, "standby starts at 9:15 and waits for 10 minutes. After enabling standby, cancel standby, and repeat the standby state for 10 minutes every 60 minutes. "
Input "# 0915 * 10 * 60 #". In S37, whether or not to input the resetting is input as in S36. In order to make the above settings, the mobile terminal includes, in addition to a numeric keypad, an input unit such as a mode changeover switch or a changeover key, a liquid crystal display unit (LCD), and a memory (RAM) for storing setting data. It is preferable.

In the embodiment described above, the exchange C is
Although a function for managing the standby time of each mobile terminal is provided, a function equivalent to this may be provided in a specific mobile terminal (hereinafter referred to as a management terminal). At this time, the management terminal stores the notification of the standby request time, the storage of the standby request time and the standby time, the notification of the message to the sender, the recording and notification of the voice message from the sender, and the storage It also performs various functions such as managing standby time and making calls to mobile terminals that are out of communication.

Therefore, as shown in FIGS. 7 and 8, the management terminal must internally have the same structure as the exchange C of FIGS. 1 and 4. In this way, by providing a management terminal, it is not a switch owned by a network operator,
The standby terminal can be effectively managed by the management terminal which is one mobile terminal that the user can possess.

[0083]

According to the present invention, an incoming call waiting state of a mobile terminal can be centrally managed in an exchange, and effective waiting of incoming call can be managed and battery consumption of the mobile terminal can be effectively reduced. In addition, useless calling operations by the exchange can be reduced, and therefore the line utilization efficiency can be improved.
