Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile terminal switching system, and more particularly to a mobile terminal switching system including a battery-driven mobile terminal and an exchange capable of setting an incoming call waiting state or the like.
[0002]
[Prior art]
Conventionally, in a mobile terminal such as a mobile phone, a “call mode” for making a call similar to that of an ordinary general subscriber telephone, an incoming call waiting state for receiving an incoming call from another mobile terminal or a general subscriber telephone (hereinafter, There are various operation modes such as “standby mode”, which is also called “standby state”, and “disconnect mode” in which the power is cut off and neither outgoing nor incoming calls can be made. Among these, in the “standby mode”, power is saved by supplying power only to circuits necessary for incoming calls.
The reason why the various operation modes are provided in this manner is that a mobile terminal such as a mobile phone is generally driven using a battery such as a nickel-cadmium battery, and it is necessary to prevent the battery from being consumed as much as possible. .
[0003]
[Problems to be solved by the invention]
However, when the “standby mode” is set, since the mobile phone supplies power only to the circuit necessary for incoming calls, the battery is saved but is consumed.
On the other hand, when the user wishes to receive an incoming call, the user sets the “standby mode”, but often forgets to set the “standby mode”. At this time, since the battery is left in the “standby mode”, the battery may be exhausted and cannot be used when a call is necessary.
[0004]
Further, in order to prevent the battery from being consumed as much as possible, when the user thinks that the battery is not used, the power may be turned off each time. However, in some cases, an important call cannot be received.
In addition, frequently turning off / on the power and repeatedly setting the “standby mode” in order to prevent the battery from being consumed are burdensome to the user and may cause a setting error.
[0005]
The present invention has been made in view of the above circumstances. When a call waiting is requested, the user can set the mobile terminal to the “standby mode”. The purpose is to effectively notify the mobile terminal after the “standby mode” setting that there is an invalid call when it is not in “standby mode”. The purpose is to prevent the consumption of the battery.
[0006]

  The present invention relates to a mobile terminal switching system comprising a mobile terminal capable of receiving an incoming call waiting state and an exchange for exchanging a call between the mobile terminals, and any mobile terminal sets itself in the incoming call waiting state. A standby time notifying unit 1 is provided for notifying the switchboard of a standby time and a standby request time that the mobile terminal desires to be in a standby state for receiving calls from other mobile terminals. The present invention provides a mobile terminal switching system including an information storage unit 6 for storing.
[0007]
In addition, when a standby request time for a specific mobile terminal is stored in the information storage unit 6 of the switch, when the communication is performed between the mobile terminal and the switch, the switch The present invention provides a mobile terminal switching system characterized by notifying the mobile terminal of a reception request time.
Here, the exchange may notify the mobile terminal of a standby request time for the mobile terminal by voice.
[0008]
In addition, the mobile terminal has a standby time setting unit 3, and the standby time setting unit 3 sets a time corresponding to the standby request time notified from the exchange as a standby time. You may make it be in an incoming call waiting state only during.
[0009]
Further, according to the present invention, the mobile terminal further includes a message notification unit 2 for notifying the exchange of predetermined message information, and the exchange further stores a message information storage unit 4 for storing the notified message information, A mobile terminal switching system is provided that includes an information notification unit 5 that notifies message information to a corresponding mobile terminal at a predetermined timing.
[0010]
Here, when message information for the mobile terminal is stored in the message information storage unit 4 of the exchange while the mobile terminal's own standby time is stored in the information storage unit 6 of the exchange, When the time falls within the own standby time, the information notification unit 5 may notify the mobile terminal of message information for the mobile terminal.
[0011]
Further, when message information for the mobile terminal is stored in the message information storage unit 4 of the exchange when the standby time of the mobile terminal is not stored in the information storage unit 6 of the exchange, a predetermined time interval The information notification unit 5 may notify the mobile terminal of message information for the mobile terminal periodically or at random time intervals.
[0012]
Further, when any mobile terminal A tries to call the mobile terminal B but does not respond, the exchange notifies the mobile terminal B of a voice message corresponding to the fact that the mobile terminal B did not respond. May be.
[0013]
As described above, the mobile terminal switching system of the present invention is composed of a mobile terminal and an exchange, and so-called communication control such as outgoing / incoming calls, telephone calls, and data transmission / reception between the mobile terminal and the exchange is generally wireless. Therefore, both the mobile terminal and the exchange are equipped with hardware that executes a wireless communication function.
In addition to the mobile terminal, a general subscriber telephone using a wire may be connected to the exchange.
[0014]
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 a standby time notification function and a standby time setting function is stored in the RAM or the ROM.
The peripheral circuit includes a communication controller for transmitting data and voice, a call circuit, and the like.
[0015]
Here, the standby time notified to the exchange, the standby request time, and message information are input directly from an input device such as a numeric keypad, or a number corresponding to message information stored in advance in a RAM or the like is input. You may be made to do.
[0016]
The standby time and the standby request time are both preferably expressed from the time at which the mobile terminal should start the incoming call waiting state and the time at which the standby state should end, but the standby state is expressed by the time width to continue. May be.
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 sets the time as the standby time in the RAM or the like. However, when the current time reaches the set standby time, the mobile terminal drives at least a circuit necessary for waiting for an incoming call.
A circuit necessary for waiting for an incoming call is, for example, a microcomputer, a communication controller, or the like.
[0017]
The exchange includes a message information storage unit 4 and an information storage unit 6, which can be composed of a storage device such as a RAM or a hard disk.
Further, the exchange has a function of notifying the mobile terminal of the standby request time, but the standby request time may be notified as data, or may be notified to the user of the mobile terminal as voice.
In the case of notification as data, a so-called microcomputer and a communication controller are provided in the exchange, and in the case of notification as voice, a memory such as a RAM is further provided, and a voice message that becomes several template sentences in advance. May be stored.
[0018]
Further, the exchange includes an information notification unit 5 that notifies the mobile terminal of 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 a ROM or the like, or may be data or voice input from an input device.
[0019]
The information notification unit 5 of the exchange preferably includes a timer in order to notify the mobile terminal of message information at a predetermined timing.
Here, the predetermined timing may be a time set in advance in a ROM, a RAM or the like, a periodic time at a predetermined time interval, or a random time interval.
“Set time” means, for example, 10:00 every day.
“Periodic at a predetermined time interval” means, for example, repeating the notification infinitely every 1 minute or repeating the notification 10 times every 10 minutes.
“Random time interval” means, for example, that notification is performed ten times at an arbitrary time in one hour.
[0020]
In addition, when the standby time of the mobile terminal that notifies the message information is set in the exchange, the predetermined timing means after the current time becomes the standby time, and the standby time is reached. After that, message information is notified.
[0021]
As described above, according to the present invention, since the mobile terminal notifies the exchange of the standby time of its own mobile terminal, and the exchange stores the standby time, all the contents accommodated in the exchange are stored. It is possible to centrally manage the incoming call waiting state of the mobile terminal.
In addition, since it is possible to notify the mobile terminal A of the time (standby request time) that a certain mobile terminal A wants to be in an incoming call waiting state via the exchange, the mobile terminal A can receive this standby request time. By only setting the incoming call waiting state, the incoming call waiting can be effectively managed, and the battery consumption can be reduced.
[0022]
In addition, since the mobile terminal sets a time corresponding to the standby request time as its standby time and is in a standby state only during the standby time, the user voluntarily waits for standby. Even if the time is not set, the incoming call standby state is automatically entered only for the required time, so that effective incoming call management can be performed, and battery consumption due to forgetting to cancel the incoming call standby state can be prevented.
[0023]
In addition, according to the present invention, since the standby request time is notified by voice, the user of the notified mobile terminal receives an important call by setting the standby time to include the requested standby time. Effective incoming call management and battery consumption can be prevented without invalidation.
[0024]
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. Effective management of call operation and notification of message information is possible.
That is, useless call operation from the exchange to the mobile terminal can be reduced, and therefore the line utilization efficiency can be improved.
[0025]
Furthermore, since the mobile terminal B is notified of the voice message corresponding to the non-response of the mobile terminal B via the exchange from any mobile terminal A, the mobile terminal B receives the voice message. The user of terminal B can immediately make a response call to mobile terminal A.
[0026]

Message No. 3 and no. Although 4 has a variable part, the start time, end time, and time interval of the standby time are inserted into the variable part. Since the variable part is determined based on information notified later from the mobile terminal, it is stored as a blank.
The stored message text is preferably given a serial code number for the convenience of reading.
[0030]
The standby time message sentence model extraction unit C4 is a part that extracts a template corresponding to the code number designated by the message sentence designation code memory from the storage unit C3.
The standby time message sentence model editing unit C5 synthesizes the message sentence by inserting information stored in the message padding parameter memory 11, for example, the start time of standby, into a blank portion in the extracted template sentence. Part.
The message text synthesized here is stored in the standby time message storage unit C6.
[0031]
The designated standby time message extraction unit C7 is a part that extracts a message sentence stored in the standby time message storage unit C6 and gives it to the speech synthesis unit C9 when a predetermined condition is satisfied.
The speech synthesizer C9 is a part that converts a given message sentence into synthesized speech based on a phoneme C8 stored in advance.

The caller telephone number memory C13 is a part that stores the telephone number of the mobile terminal that has made a call to the exchange C.
[0035]
Next, an outline of the operation of the standby time management unit when 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 transmission / reception unit C16 of the exchange stores the telephone number of the mobile terminal A in the caller telephone number memory C13.
In the information transmitted from the mobile terminal A, it is assumed that the designation code = “3”, the filling parameter = “start: 10:00, end: 12:20” and the other party's telephone number are inserted.
Here, the numeric keypad information analysis unit C14 analyzes the information and stores it in the corresponding memories (C10, C11, C12).
[0036]
The standby time message sentence template extraction unit C4 refers to the designation code = “3” stored in the message sentence designation code memory C10 and corresponds to the designation code from the basic standby time message sentence template storage unit C3. The template sentence is read out and sent to the standby time message sentence template editing unit C5.
Here, “Standby time in FIG. : ~ : Is read out.
[0037]
The standby time message text template editing unit C5 determines that “ready” from the read template text and the parameters stored in the message filling parameter memory C11 = “start: 10:00, end = 12: 20”. The message is created as “Time is 10: 00 to 12:20”.
Thereafter, 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 party telephone number memory C13. Store phone numbers as a set.
The above is the operation for storing the standby request time in the exchange.
[0038]
Thereafter, when a call is made from the mobile terminal B having the same number as the destination telephone number stored together with the message stored in the standby time message storage unit, the stored message is read. The mobile terminal B is notified by voice.
That is, when a call is made from the mobile terminal B, the telephone number of the mobile terminal B is stored in the caller telephone number memory C13.
[0039]
The designated standby time message extraction unit C7 stores the destination telephone number stored in a pair with the message text stored in the standby time message storage unit C6 and the caller telephone number memory C13. The message number is read and given to the speech synthesizer C9.
For example, when the other party's telephone number corresponding to the message sentence “the standby time is 10:00 to 12:20” matches with the mobile terminal B, this message sentence is given to the speech synthesizer C9.
[0040]
The voice synthesizer C9 reads out the phoneme corresponding to the message sentence from the phonemes 8, performs voice synthesis, and notifies the mobile terminal B of the message sentence by voice through the transmitter C15 and the transmitter / receiver C16.
Here, the standby time message registration unit C2, the basic standby time message text sample storage unit C3, the standby time message text template extraction unit C4, the standby time message text template editing unit C5, the designated standby time message The operation subject of the extraction unit C7 and the numeric keypad information analysis unit C14 is generally a microcomputer, and each unit operates according to a program stored in a ROM or the like.
[0041]
FIG. 3 shows an embodiment of a sequence in the case of 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 a non-standby state. In other words, it is assumed that the incoming call cannot be made due to power-off or the like because the battery is turned off.
[0042]
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 wants the mobile terminal B to wait for an incoming call. The time, that is, the standby request time and the message code number are registered by a predetermined operation using the numeric keypad (S2).
This registration information is transferred to the exchange and stored in the memory inside the exchange as described above (S3).
[0043]
Thereafter, it is assumed that the mobile terminal B is powered on by the user (S4).
At this time, when the user operates or when the power is turned on, a call for inquiring whether or not his / her standby request time is registered is automatically made to the exchange (S4). ).
Since this call is different from the purpose of a call with another normal mobile terminal, for example, a predetermined special number may be dialed.
[0044]
Upon receiving the special number call from the mobile terminal B, the exchange confirms whether the standby request time for the mobile terminal B is not registered (S5). If registered, as described above, the mobile terminal B is notified of the message text (see FIG. 2) including the standby request time by voice.
The user of the mobile terminal B who has heard the notification of the message text by voice sets a standby time corresponding to the message text (S6).
When the standby time is set, if the mobile terminal B includes the current time, the mobile terminal B may continue the power-on state as it is, but the set standby time does not include the current time. If so, turn off the power automatically.
In this way, battery consumption can be effectively prevented.
[0045]
When the set standby time comes after the power is turned off to enter the non-standby state, the mobile terminal B automatically enters the standby state (S7).
Therefore, power is supplied to the circuit portion necessary for the standby state, and the incoming call is received.
Thereafter, if an 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 can perform a conversation between the mobile terminals A and B.
Further, when the end time of the set standby time comes, the mobile terminal B automatically releases the standby state and enters a non-standby state (S9).
[0046]
As described above, since the standby state of the mobile terminal B is set based on a standby time setting request from another mobile terminal A, the battery of the user of the mobile terminal B is consumed. Management burden can be reduced, and effective incoming call management and prevention of battery consumption can be performed effectively.
[0047]
Further, 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 sets the standby request time of its own. Although the standby time is set, the exchange notifies the mobile terminal B of the standby request time in a data format, and the standby request time in the data format is received by the microcomputer in the mobile terminal B. May be set automatically.
In this way, since only the time necessary for incoming calls is automatically set in the incoming call waiting state, it is possible to prevent the user from forgetting to set the standby time or to make an incorrect setting, and to perform effective incoming call management.
[0048]
Further, it is possible to prevent the battery from being consumed due to the user forgetting to cancel the incoming call waiting state.
The exchange C can easily notify the mobile terminal B of the standby request time in a data format by a microcomputer and a communication controller in the exchange. Further, the mobile terminal B may be provided with a standby time setting unit for setting the standby request time notified in the data format as its own standby time. The function of this part is also provided with the microcomputer and the necessary program. Can be easily realized.
[0049]
Example 2
Here, in the mobile terminal switching system of the present invention, an embodiment in the case of performing notification management of messages corresponding to the standby state is shown.
FIG. 4 shows a configuration block diagram of a portion according to the second embodiment in the standby time management unit of the exchange.
[0050]
In FIG. 4, a “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 or not the mobile terminal k is in the “power-off” state is determined by the counterpart power-off detection unit C28.
When a call is made from another mobile terminal m to the mobile terminal k, the exchange C calls the mobile terminal k. If there is no response from the mobile terminal k for a certain period of time, the exchange C It can be determined that the power is off.
That is, when the partner power cut-off detection unit C28 of the exchange C detects that the call to a certain mobile terminal k has ended abnormally, the mobile terminal k is powered off to the “power cut-off” message sending unit C27. And stores it in the “power-off” storage unit C21.
[0051]
Here, the “power cut-off” message sending unit C27 sends a notification of a message that “the mobile terminal k is not in the standby state” to the mobile terminal m that has made a call to the mobile terminal k. The part to do.
The recording timing generation unit C26 starts and stops the recording operation of the voice message sent from the mobile terminal m thereafter in response to a request from the “power-off” message sending unit C27.
[0052]
The recording of the voice message is performed by the message recording unit C22 based on the timing sent from the recording timing generation unit C26.
The voice message is stored in a memory in the message recording unit C22.
The receiving unit C29 performs A / D conversion on the voice message sent through the transmission / reception unit C16 and supplies the voice message to the message recording unit C22.
[0053]
The numeric keypad information input unit C30 receives information such as a 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 C31.
The clock unit C33 is a so-called timer, and counts the current time and the elapsed time from the set time.
[0054]
The standby time determination unit C24 determines whether or not information indicating that “the standby time is stored” is stored in the standby information storage unit C31, and the current time is the standby time storage unit C23. It is determined whether or not the standby time stored in is reached.
The message extraction unit C25 is a part that reads the voice message stored in the message recording unit C22 in response to the activation request from the standby time determination unit C24.
Also, the read voice message is notified to the corresponding mobile terminal through the transmission / reception unit C16.
The above is the configuration of the part of the standby time management unit of the exchange C that performs notification management of messages corresponding to the standby state, and the operation of these parts is usually controlled by a microcomputer.
[0055]
Next, when a call is made from a certain mobile terminal A to the mobile terminal B but the call is interrupted, a sequence for notifying the mobile terminal B of a voice message from the mobile terminal A is sent to the mobile terminal C. The case where B's own standby time is stored and the case where it is not stored will be described separately.
[0056]
FIG. 5 shows an example of a sequence in the case where the own 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 a numeric keypad to register its own standby time (S11).
That is, the user of the mobile terminal B turns on the power and inputs a start time and an end time or a time width of the standby time by a predetermined operation.
After this input is completed, the mobile terminal B communicates with the exchange C by a special number dial for standby time registration and requests registration of the standby time.
[0057]
The exchange C stores the standby time sent from the mobile terminal B in the standby time storage unit C23 as that of the mobile terminal B through the numeric keypad information input unit C30.
For example, “mobile terminal B”, standby start time, and standby end time are stored. At the same time, the numeric keypad information input unit C30 stores the information standby information storage unit C31 indicating that the standby time of the mobile terminal B is stored.
For example, a flag is set in the memory area corresponding to the mobile terminal B.
With the above operation, the mobile terminal B's own standby time is registered in the mobile terminal B itself and the exchange C (S12).
[0058]
In addition, after the registration is completed, the user of the mobile terminal B may turn off the power to save the battery if it is not the current standby time.
Alternatively, when the current standby time is not reached, the microcomputer in the mobile terminal B may automatically shift to a power saving state rather than the standby state.
In this way, battery consumption due to forgetting to turn off the power can be reduced.
[0059]
Next, it is assumed that a call is made from the mobile terminal A to the mobile terminal B when the mobile terminal B is in a non-standby state where the power is turned off (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 a power-off state.
As described above, this detection operation is performed by the counterpart power-off detection unit C28 and activates the “power-off” message sending unit C27.
[0060]
Thereafter, the “power-off” message sending unit C27 stores in the “power-off” storage unit C21 that the mobile terminal B is in the “power-off” state, and “the mobile terminal B is in the power-off state. If there is a message to B, please tell us later. "A message to the effect that" the message is sent to B "is sent to the mobile terminal A and the recording timing generation unit C26 is activated.
[0061]
The user of the mobile terminal A speaks the message to the mobile terminal B after listening to the message from the exchange C (S14).
This message is recorded in the message recording unit C22 through the receiving unit C29 of the exchange C (S15).
The recorded message is given an identifier indicating that it is for the mobile terminal B.
[0062]
In the exchange C, the standby time determination unit C24 always confirms that information indicating that the standby time is stored is stored in the standby information storage unit C31.
Since it is determined that information indicating that “the standby time of the mobile terminal B is stored” is currently stored in the standby information storage unit C31, the standby time determination unit C24 The standby time of the mobile terminal B stored in the storage unit C23 is read, and the standby time of the mobile terminal B is compared with the current time read from the clock unit C33.
[0063]
At this time, when it is confirmed that the current time is within the standby time of the mobile terminal B, the exchange C performs the calling operation of the mobile terminal B (S17).
On the other hand, also in the mobile terminal B, the microcomputer always checks whether or not the current time has reached the standby time set by itself, and automatically enters the standby state when the standby time comes. (S16).
That is, in the mobile terminal B, in order to enter the incoming call waiting state, power is supplied to a circuit necessary for incoming call.
Therefore, the mobile terminal B should surely answer the incoming call to the call of the mobile terminal B made by the exchange C.
[0064]
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 unit C22 (S17).
Here, whether or not the mobile terminal B has responded may be determined by an incoming call detection function that is not shown in FIG. 4 but is a basic function of the exchange C. Part C24 is notified.
[0065]
Further, the standby time determination unit C24 gives an instruction to read the recorded message for the mobile terminal B to the message extraction unit C25, the desired recording message is read from the message recording unit C22, and further, the mobile terminal B is transmitted through the transmission / reception unit C16. To be notified.
Further, not only the recorded voice but also the telephone number of the mobile terminal A may be added to the notified message.
[0066]
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 the standby time of the mobile terminal B. Since the calling operation of the mobile terminal B is performed after the time becomes, useless calling operation from the exchange can be prevented, and the line use efficiency of the exchange can be improved.
[0067]
Furthermore, in the exchange, it is possible to centrally manage the incoming call waiting state of all mobile terminals.
In addition, since the mobile terminal B is notified of a voice message from a destination that is disconnected in the non-standby state after entering the standby state, it is effective without invalidating important incoming calls. Incoming call management.
Further, since the mobile terminal is automatically moved to and released from the standby state, effective battery consumption can be prevented.
[0068]
Next, FIG. 6 shows an example of a sequence when the mobile terminal B's own standby time is not stored in the exchange C.
In the figure, each operation of calling the mobile terminal B by the mobile terminal A (S21), no response from the mobile terminal B, registering the message to the mobile terminal B (S22), and storing the message in the exchange (S23). Is the same as that shown in FIG. 5 and will not be described here.
[0069]
The embodiment shown in FIG. 6 differs from the embodiment shown in FIG.
That is, when the mobile terminal B's own standby time is stored in the exchange C, the operation of calling the mobile terminal B is started when the current time is within the standby time. The embodiment differs in that the mobile terminal B is called at a random timing or a regular timing after the storage of the message to the mobile terminal B (S23) ends.
[0070]
Here, for example, the random time interval may be called 10 times at an arbitrary time in one hour, or may be called unlimitedly at an arbitrary time interval.
In addition, the calling operation may be performed periodically, such as calling 10 times every 10 minutes or without limitation every hour.
[0071]
In storing the message to the mobile terminal B shown in FIG. 6 (S23), the voice message is stored in the message recording unit C22.
Thereafter, the standby time determination unit C24 recognizes that the message to the mobile terminal B has been stored in the message recording unit C22, and further, in the standby information storage unit C31, “the own standby time of the mobile terminal B”. When it is detected that the information “is stored” is not stored, a random number is generated to determine the time for calling the mobile terminal B.
Then, the exchange C continues the call operation at random time intervals until the mobile terminal B answers the incoming call (S24).
[0072]
When the mobile terminal B is called after entering the standby state (S25), the mobile terminal B responds to the incoming call, but the voice message from the mobile terminal A is sent to the mobile terminal B as in S17 of FIG. Notification is made (S26).
[0073]
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 performing at random timing, the reserved voice message can be notified immediately after the mobile terminal B enters the standby state.
[0074]
Further, if the mobile terminal B automatically makes a call to the exchange C after the standby state is set, the exchange C can promptly send a message to the mobile terminal B as shown in S23. Mobile terminal B can be notified.
[0075]
As described above, in the mobile terminal, the standby time is set by the user or automatically. For example, a mode in which no incoming call is received (non-standby state), a mode in which standby is always performed ( It is possible to set various modes, such as a mode that waits for an incoming call only during a specified time period (time designation), and a mode that waits for an incoming call at a random or fixed period (period). Also good.
[0076]
Further, a standby time management mode for setting each of the above modes and a call mode that enables a normal call may be provided.
These mode settings may be set by providing a mode switch on each mobile terminal or by a predetermined operation using a numeric keypad.
In addition, necessary parameters are input using a numeric keypad or the like for each mode. Here, the necessary parameters are, for example, a time zone to be set in the time setting mode.
[0077]
FIG. 7 shows a flowchart of an example of mode setting in the mobile terminal.
The user sets the mode switch to the standby time management mode (S31).
Here, the “current setting mode” and the “current standby time” in the mobile terminal are displayed on the LCD or the like, and the input waiting for whether the setting can be changed (1 #) or not (0 #) is entered (S32). ).
[0078]
When NO (0 #) is input, the standby time management state is entered. If the current standby time is not reached, the power is turned off (S38).
When “1 #” is input in S32, “standby time designation” or “cycle designation” is displayed, and input waiting for time designation (0 #) or period designation (1 #) is entered ( S33).
[0079]
Here, when the user inputs the time designation (0 #), the standby time is input next (S34).
For example, as shown in FIG. 7, when “9:15 to 17:30” is set as the standby time, “# 0915 * 1730 #” is input.
Next, if the input is correct, a standby time management state is entered when NO (0 #) is input (S38).
When resetting is performed again for input correction or the like, “Yes (1 #)” is input (S36), and the process returns to S34.
[0080]
In S33, when the cycle designation (1 #) is input, the user inputs the standby time. Here, for example, “the standby starts at 9:15 and the standby for 10 minutes is valid. In the case where the standby is canceled and the standby state for 10 minutes is repeated periodically every 60 minutes, “# 0915 * 10 * 60 #” is input.
In S37, whether or not resetting can be input is input as in S36.
In order to perform the setting as described above, the mobile terminal includes an input unit such as a mode switch or a switching key, a liquid crystal display unit (LCD), and a memory (RAM) for storing setting data in addition to the numeric keypad. It is preferable.
[0081]
In the embodiment described above, the exchange C is provided with a function for managing the standby time of each mobile terminal, but a function equivalent to this is provided in a specific mobile terminal (hereinafter referred to as a management terminal). May be.
At this time, the management terminal stores the notification of the standby request time performed by the exchange, the storage of the standby request time and the standby time, the notification of the message to the transmission source, the recording and notification of the voice message from the transmission source, and the storage. Each function such as management of standby time and calling operation to a mobile terminal that has been disconnected is executed.
[0082]
Therefore, as shown in FIGS. 7 and 8, the management terminal needs to have the same configuration as the exchange C in FIGS. 1 and 4 inside.
In this way, by providing a management terminal, standby management can be effectively performed by a management terminal that is a mobile terminal that can be held by a user, not by a switch owned by a network operator.
[0083]
【The invention's effect】
According to the present invention, the exchange can centrally manage the incoming call waiting state of the mobile terminal, and can effectively reduce battery consumption of the mobile terminal along with effective incoming call waiting management.
In addition, useless call operation by the exchange can be reduced, and therefore the line utilization efficiency can be improved.
