  In the present embodiment, the functional configuration is logically realized by the control unit 310 executing a program. However, these functions may be realized by a physical configuration such as an ASIC, for example. Good.

  The operation of the mobile communication system 1 configured as described above will be described below with reference to the drawings. First, a standby number setting process for selecting and setting a telephone number to be set in a standby state (hereinafter referred to as “standby number”) from a plurality of telephone numbers that can be used in the mobile communication terminal 100 is illustrated in FIG. This will be described with reference to the flowchart shown in FIG. This standby number setting process is realized by cooperation between the mobile communication terminal 100 and the management apparatus 300. In the present embodiment, it is assumed that the processing is started when the IC card 161 is attached to the card interface 160 of the mobile communication terminal 100.

  When the process is started, the telephone number processing unit 113 of the mobile communication terminal 100 accesses the variable information storage unit 180 and stores the telephone number information recorded in the attached IC card 161 in the telephone number information storage area 181. Is stored in the main body of the mobile communication terminal 100 (step S101).

  When the telephone number of the attached IC card 161 is added to the telephone number information storage area 181, the telephone number processing unit 113 displays a standby number selection screen for inquiring the user as to which telephone number is the standby number. The information is displayed on the unit 140 (step S102). A display example of the standby number selection screen is shown in FIG. As shown in the figure, a plurality of telephone numbers stored in the telephone number information storage area 181 are displayed on the standby number selection screen so as to be selectable.

  In the present embodiment, any one of a plurality of telephone numbers that can be used in the mobile communication terminal 100 is set in a standby state, and the other telephone numbers are set in a non-standby state. Reduce power consumption more than necessary by putting numbers in standby mode at the same time. Therefore, the user operates the operation unit 130 to select one from a plurality of available telephone numbers.

  Here, business use and private use are assumed as examples of proper use of telephone numbers. A business telephone number is, for example, a contract with a carrier CR by a company to which a user belongs, and for example, the company pays a usage fee for the telephone number. On the other hand, the private telephone number is a contract with the carrier CR by the user himself / herself. For example, the user himself / herself pays a usage fee for the telephone number.

  In the present embodiment, it is assumed that telephone number information contracted for private use is recorded in the fixed information storage unit 170, and a business telephone number can be used by attaching an IC card 161 as an example. explain. Here, in the present embodiment, it is assumed that the business phone number is notified only to the parties involved in the user's work (for example, colleagues and business partners), and the private phone number is the user's private phone number. It is assumed that only related parties (for example, family members and friends) are notified.

  Moreover, in the example shown below, the case where the mobile communication terminal 100 is utilized during a user's work time is assumed. Therefore, it is assumed that the user selects a business telephone number from the standby number selection screen displayed in step S102. In this embodiment, since the business phone number is stored in the IC card 161, the business phone number cannot be used unless the IC card 161 is attached to the mobile communication terminal 100. Therefore, it is assumed that the user of the mobile communication terminal 100 attaches the IC card 161 to the mobile communication terminal 100 at the start of work time and switches the standby number from a private telephone number to a business telephone number.

  In this case, the user operates the operation unit 130, selects a telephone number (hereinafter referred to as “new standby number”) that is to be newly set as a standby number, and selects a “decision” button. Thereby, telephone number information (hereinafter referred to as “new number information”) indicating the new standby number is input to the control unit 110. The input new number information is held in the work area. In this embodiment, the business telephone number recorded on the IC card 161 corresponds to the new standby number.

  When a new standby number is selected by a user operation, the telephone number processing unit 113 displays a password input screen for inputting a password required for authentication of a user who performs standby number switching on the display unit 140. (Step S103). A display example of the password input screen is shown in FIG. The user operates the operation unit 130 to input a personal identification number for a telephone number (hereinafter referred to as “previous standby number”) that is currently set as a standby number in the mobile communication terminal 100, and Select a button. As a result, the password information indicating the input password is input to the control unit 110. The entered password information is held in the work area. In the present embodiment, the private telephone number stored in the fixed information storage unit 170 corresponds to the pre-standby number.

  When the personal identification number is input, the telephone number processing unit 113 instructs the registration processing unit 111 to perform processing for registering the new standby number in the management apparatus 300. The registration processing unit 111 controls the transmission control unit 122 in accordance with an instruction from the telephone number processing unit 113, and selects the new number information selected and the telephone number information indicating the previous standby number (hereinafter referred to as “current number information”). ”), A personal identification number for the input prior standby number, a terminal ID stored in the fixed information storage unit 170, and header information indicating a registration request to the management apparatus 300. The standby number registration request is transmitted to the management apparatus 300 (step S104).

  In this case, the standby number registration request is relayed from the nearby base station 25 to the exchange 200. In the exchange 200, when the reception control unit 223 receives a standby number registration request from the mobile communication terminal 100, the terminal processing unit 224 analyzes the header information and is a standby number registration request to the management apparatus 300. Recognize that. In this case, the terminal processing unit 224 notifies the management device request unit 244 of the received standby number registration request. The management device request unit 244 sends a standby number registration request to the management device 300 via the transmission control unit 242 and the management device communication unit 241.

  In the management apparatus 300, when the reception control unit 322 receives the standby number registration request from the mobile communication terminal 100 via the exchange 200 (step S105), based on the information stored in the registered terminal information storage area 351. The terminal information registration processing unit 312 authenticates the standby number registration request.

  Here, for example, when the combination of the telephone number, the terminal ID, and the personal identification number indicated by the current number information included in the standby registration request is not correct, the terminal information registration processing unit 312 issues the standby registration request. Authentication is not performed (step S106: No). In this case, for example, the error message is notified to the mobile communication terminal 100, and the process is terminated.

  On the other hand, when the standby number registration request is authenticated (step S106: Yes), the terminal information registration processing unit 312 requests the mobile communication terminal 100 to execute a location registration operation using the new standby number. The location registration request to be transmitted is transmitted to the mobile communication terminal 100 via the communication processing unit 311 (step S107).

  The location registration request transmitted by the management apparatus 300 is relayed to the mobile communication terminal 100 by the exchange 200. In this case, when the location registration request is received from the management apparatus 300 by the reception control unit 243 of the exchange 200, the location registration request is transmitted to the mobile communication terminal 100 by the operation of the terminal request unit 225.

  In the mobile communication terminal 100, when the location registration request is received by the operation of the reception control unit 123 (step S108), the registration processing unit 111 controls the transmission control unit 122 and the reception control unit 123, and wirelessly uses the new standby number. It communicates with a nearby base station 25 by communication, acquires position information transmitted by the base station 25, and stores it in the position information area 182 (step S109). The registration processing unit 111 controls the transmission control unit 122 to transmit location registration information including the selected new standby number, terminal ID, and location information acquired in step S109 to the management apparatus 300 ( Step S110).

  The location registration information transmitted from the mobile communication terminal 100 is relayed to the management device 300 by the exchange 200 as in the case of the standby number registration request. At this time, the exchange 200 stores the relayed location registration information in the terminal information storage unit 251.

  When the management apparatus 300 receives the location registration information relayed by the exchange 200 (step S111), the terminal information registration processing unit 312 accesses the registered terminal information storage area 351, and records the telephone number information indicated by the location registration information. In addition, by storing the received position information, the position registration for the new standby number requested from the mobile communication terminal 100 is performed (step S112). The terminal information registration processing unit 312 also records other telephone number information associated with the same terminal ID as the terminal ID included in the location registration information (that is, a record in which a previous standby number is recorded). And the position information recorded in the record is deleted (step S113). Thereby, based on the presence / absence of the location information, which telephone number is set as the standby number in the mobile communication terminal 100 is indicated.

  The terminal information registration processing unit 312 transmits a standby number registration completion notification to the mobile communication terminal 100 via the communication processing unit 311 (step S114), and ends the process.

  The registration completion notification is relayed to the mobile communication terminal 100 by the exchange 200. In the mobile communication terminal 100, when the registration completion notification is received from the management device 300 (step S115), the telephone number processing unit 113 accesses the telephone number information storage area 181 and waits for the telephone number information indicating the new standby number. The process is terminated by turning on the reception identification flag and displaying a message indicating that the registration is completed on the display unit 140.

  Through the above processing, the standby number at the mobile communication terminal 100 is set in the mobile communication terminal 100 and the management apparatus 300. That is, a business telephone number is set as a standby number. In this state, the mobile communication terminal 100 normally receives a call to the set standby telephone number, but the mobile communication terminal 100 does not receive a call to another telephone number that can be used by the mobile communication terminal 100. I do not receive a call. In the example of the present embodiment, the business phone number stored in the IC card 161 is used as the standby number, so the private phone number stored in the fixed information storage unit 170 is in a non-standby state. . Therefore, even when a call is made to the private telephone number, the mobile communication terminal 100 does not receive a call.

  However, it may be inconvenient if not all calls for telephone numbers that are in a non-standby state (hereinafter referred to as “non-standby numbers”) are received. For example, it is not desirable that an incoming call cannot be made when an emergency contact from a family arises. Therefore, in this embodiment, only when a specific requirement is satisfied, an operation of automatically switching the corresponding non-standby number to the stand-by number is performed so that a call to the non-standby number can be received.

  Processing of the mobile communication system 1 for performing such operations will be described below. This standby number switching operation is executed by the cooperation of the mobile communication terminal 100, the exchange 200, and the management device 300. In the present embodiment, a case where a call is made from an external terminal to the mobile communication terminal 100 will be described below as an example.

  First, incoming call processing by cooperation between the exchange 200 and the management apparatus 300 will be described with reference to the flowchart shown in FIG. This incoming call processing is started when the exchange 200 receives an incoming call request from the external terminal to the mobile communication terminal 100. Note that the incoming request from the external terminal to the mobile communication terminal 100 is a normal incoming request, and at least the telephone number of the caller (that is, the telephone number of the external terminal) and the telephone number of the callee (that is, the mobile body). Phone number of the communication terminal 100).

  First, the reception control unit 233 of the exchange 200 establishes a communication path between the external terminal and the exchange 200 by receiving an incoming request from the external terminal by the operation of the external network communication unit 231 (step S201). Then, the central processing unit 210 assigns a unique incoming call request ID to the received incoming call request, creates a record in the relay processing information storage unit 252, and the caller telephone number indicated by the incoming call request (that is, the telephone number of the external terminal) Then, telephone number information indicating each of the destination telephone numbers (requested telephone numbers) for which the caller requests connection is stored (step S202). In addition, when the exchange 200 receives an incoming request from an external terminal, a communication path between the external terminal and the exchange 200 is established.

  When the telephone number information related to the incoming request is stored in the relay processing information storage unit 252, the central processing unit 210 notifies the management apparatus request unit 244 of the assigned incoming request ID. The management device request unit 244 accesses the relay processing information storage unit 252 and requests the management device 300 to inquire whether or not the requested telephone number associated with the notified incoming request ID is currently in a standby state. To do. In this case, a standby confirmation request including header information indicating that it is an inquiry as to whether or not it is in a standby state, an incoming request ID, and a request telephone number indicated by the incoming request is transmitted to the management apparatus 300 ( Step S203).

  In the management apparatus 300, when a standby confirmation request is received by the operation of the reception control unit 322 (step S204), the communication processing unit 311 analyzes the header information and determines that the request is a standby confirmation request. In this case, the communication processing unit 311 notifies the search / authentication processing unit 313 of the received standby confirmation request. The search / authentication processing unit 313 accesses the terminal information storage unit 251 in response to the notification from the communication processing unit 311 and searches for a record in which the requested telephone number included in the standby confirmation request is recorded (step). S205).

  The search / authentication processing unit 313 determines whether or not position information is recorded in the searched record. Here, if the location information is recorded, the telephone number is in a standby state, and if it is not recorded, it is in a non-standby state. The search / authentication processing unit 313 creates answer information indicating whether the requested telephone number indicated by the incoming call request is in a standby state or a non-standby state according to the determination result. The search / authentication processing unit 313 adds the corresponding incoming request ID to the response information, returns it to the exchange 200 via the communication processing unit 311 (step S206), and ends the process.

  In the exchange 200, when the response information is received by the operation of the reception control unit 243 (step S207), the number switching processing unit 245 determines whether or not the requested telephone number is in a non-standby state based on the response information. (Step S208).

  Here, when the destination telephone number (requested telephone number) called by the external terminal is in a standby state in the mobile communication terminal 100 (step S208: No), the number switching processing unit 245 displays the central processing unit 210. Then, the relay processing information storage unit 252 is accessed, and status information indicating that the requested telephone number is in a standby state is recorded in a record corresponding to the incoming call request ID included in the answer information. When the requested telephone number is in a standby state, the mobile communication terminal 100 can receive a call from an external terminal, so the exchange 200 transmits an incoming call request to the mobile communication terminal 100 (step S209). End the process. In this case, an incoming request from the external terminal is relayed to the mobile communication terminal 100 via the exchange 200, and a communication path between the external terminal and the mobile communication terminal 100 is established.

  On the other hand, when the destination telephone number (requested telephone number) called by the external terminal is in a non-standby state in the mobile communication terminal 100 (step S208: Yes), the number switching processing unit 245 stores the relay processing information. The status information indicating that the requested telephone number is in the non-standby state is recorded in the corresponding record of the unit 252 and the caller authentication process for authenticating the user of the calling external terminal is executed (step S300). ). This caller authentication process will be described with reference to the flowchart shown in FIG.

  Caller authentication processing is performed in cooperation between the exchange 200 and the management device 300. When the processing is started, the number switching processing unit 245 instructs the transmission control unit 232 to request the input of the personal identification number from the external terminal of the transmission source. In response to an instruction from the number switching processing unit 245, the transmission control unit 232 outputs voice guidance of a message requesting input of a personal identification number to the external terminal through the communication path established in step S201 (step S301). For example, if you know the PIN number, enter the number. If you do not know it, output a message prompting you to perform a predetermined key operation for cancellation (for example, key input other than numeric keys) to the external terminal using voice guidance. To do.

  The user of the external terminal operates the key of the external terminal in accordance with the voice guidance, and inputs a code number or a predetermined key for canceling operation.

  Here, it is assumed that the personal identification number set by the user of the mobile communication terminal 100 is notified to a specific person. In this embodiment, it is assumed that the password of the private telephone number is notified to the user's family. In the example of this embodiment, since the business telephone number is set as the standby number, if it is determined in step S207 that the requested telephone number is not in the standby state, the mobile communication terminal 100 private Called from an external terminal to the telephone number. In this case, if the family of the user of the mobile communication terminal 100 is the caller, the personal identification number is notified, so the personal identification number is input according to the voice guidance output in step S301. can do. On the other hand, if the caller is other than the user's family, the password cannot be entered because the password is not known.

  When any key operation is performed on the external terminal, a DTMF (Dual Tone Multi Frequency) signal or the like corresponding to the key operation is input to the central processing unit 210 via the reception control unit 233. The central processing unit 210 determines whether a password has been input from the external terminal based on an input signal from the external terminal (step S302).

  When the input is other than the code number (step S302: No), the central processing unit 210 instructs the transmission control unit 232 to send a call rejection notice to the external terminal that is the call source. For example, the transmission control unit 232 outputs a message indicating that the incoming call cannot be received with the calling telephone number to the external terminal by voice guidance (step S311), and ends the process.

  On the other hand, when a personal identification number is input from the external terminal (step S302: Yes), the central processing unit 210 includes request telephone number information indicated by the incoming request of the external terminal, personal identification number information indicating the input personal identification number, and To the management apparatus request unit 244, and instructs the management apparatus 300 to request authentication of the personal identification number. The management apparatus request unit 244 accesses the relay processing information storage unit 252 via the central processing unit 210, specifies a record in which the notified requested telephone number is recorded, the incoming request ID of the record, the requested telephone The personal identification number collation request including the serial number and the personal identification number information input from the external terminal is created and transmitted to the management apparatus 300 via the transmission control unit 242 (step S303).

  In the management apparatus 300, when the reception control unit 322 receives the password verification request (step S304), the request is input to the control unit 310. In this case, the communication processing unit 311 notifies the search / authentication processing unit 313 of the requested telephone number information and the personal identification number information included in the input personal identification number collation request, and instructs the authentication of the personal identification number. The search / authentication processing unit 313 accesses the registered terminal information storage area 351, searches for the record of the telephone number indicated by the notified requested telephone number information, and the PIN code recorded in the record and the notified PIN code. The personal identification number indicated by the number information is collated (step S305).

  If the passwords match (step S306: Yes), the search / authentication processing unit 313, based on the terminal ID recorded in the record in which the requested telephone number is recorded, the mobile communication terminal with the terminal ID A telephone number that is currently in a standby state at 100 (hereinafter referred to as “current standby number”) is searched (step S307). As described above, the registered terminal information storage area 351 indicates that the telephone number in which the position information is recorded is in a standby state, so that the search / authentication processing unit 313 stores the requested telephone number. A record having the same terminal ID and position information as the terminal ID of the recorded record is specified, and the telephone number recorded in the record is acquired as the current standby number of the mobile communication terminal 100 .

  The search / authentication processing unit 313 searches the mobile communication terminal 100 that has been searched when the incoming call request ID indicated in the password verification request, the verification result indicating whether the password matches or does not match, and the password. Collation result information including telephone number information indicating the standby number (hereinafter referred to as current standby number information) is generated and transmitted to the exchange 200 via the communication processing unit 311 (step S308). The process on the apparatus 300 side is terminated.

  In the exchange 200, when the verification result information is received from the management apparatus 300 by the operation of the reception control unit 243 (step S309), the number switching processing unit 245 analyzes the verification result and determines whether the password entered from the external terminal is correct or not. (Step S310).

  When the input personal identification number does not match the regular personal identification number (step S310: No), the number switching processing unit 245 instructs the transmission control unit 232 to notify the caller external terminal that the incoming call cannot be received. For example, the transmission control unit 232 outputs a message indicating that the incoming call cannot be received with the calling telephone number to the external terminal by voice guidance (step S311), and ends the process. Here, an external call made to the mobile communication terminal 100 is output by using a communication path with the caller telephone number associated with the incoming call request ID indicated by the matching result information in the relay processing information storage unit 252. The terminal is notified that the incoming call cannot be received.

  On the other hand, when the input code number matches the regular code number (step S310: Yes), the process returns to the flow of the incoming call process shown in FIG.

  Returning to the flow of the incoming call process, the exchange 200 requests the mobile communication terminal 100 that is the callee to switch the standby number, and the standby number switching process for automatically switching the standby number of the mobile communication terminal 100. Is executed (step S400). This standby number switching process is performed by cooperation between the exchange 200 and the mobile communication terminal 100. The standby number switching process will be described with reference to the flowchart shown in FIG.

  When the processing is started, the number switching processing unit 245 generates a number switching request for requesting the mobile communication terminal 100 to switch from the current standby number in the mobile communication terminal 100 to the requested telephone number indicated by the incoming call request. (Step S401), the mobile communication terminal 100 is instructed to notify the number switching request. This number switching request includes header information indicating that it is a number switching request, a corresponding incoming request ID, and telephone number information indicating the current standby number notified from the management apparatus 300 (hereinafter referred to as “pre-switching telephone number”). Information ”) and telephone number information indicating a request telephone number of an incoming request from an external terminal (hereinafter referred to as“ switched telephone number information ”).

  Terminal request unit 225 accesses terminal information storage unit 251 and acquires position information corresponding to the telephone number indicated by the telephone number information before switching (that is, the current standby number of mobile communication terminal 100). And it connects to the mobile communication terminal 100 by calling the present standby number via the base station 25 corresponding to the acquired position information (step S402). As a result, the communication path between the exchange 200 and the mobile communication terminal 100 is established using the standby number set in the mobile communication terminal 100.

  When the communication path with the mobile communication terminal 100 is established, the terminal request unit 225 transmits the number switching request created in step S401 to the mobile communication terminal 100 (step S403).

  In the mobile communication terminal 100, when the reception control unit 123 receives the number switching request (step S404), the number is input to the control unit 110. When the incoming request analysis unit 112 recognizes that a number switching request has been input based on the header information, it instructs the telephone number processing unit 113 to switch the standby number. Here, switching to the telephone number indicated by the telephone number information after switching included in the received number switching request is instructed.

  The telephone number processing unit 113 accesses the telephone number information storage area 181 and turns off the standby identification flag for the telephone number for which the standby identification flag is currently ON (that is, the telephone number before switching) (step S110). In step S405, the standby identification flag of the telephone number indicated by the notified switched telephone number information (that is, the requested telephone number from the external terminal) is turned on (step S406). Further, the telephone number processing unit 113 turns on the automatic switching flag for both telephone numbers for which the standby identification flag has been operated in steps S405 and S406 (step S407). That is, only the automatic switching flag is turned on for the telephone number before switching, and both the standby identification flag and the automatic switching flag are turned on for the telephone number after switching.

  When the standby number is switched in the mobile communication terminal 100 in this way, the telephone number processing unit 113 registers the switched telephone number (in the example of the present embodiment, a private telephone number) with the registration processing unit 111. And instruct location registration with the telephone number. In this case, the registration processing unit 111 communicates with the neighboring base station 25 using the switched telephone number, acquires the position information transmitted by the base station 25, and stores the position information in the position information area 182. The registration processing unit 111 further controls the transmission control unit 122 to transmit location registration information including the telephone number information indicating the switched telephone number and the acquired location information to the exchange 200 (step S408). The process on the mobile communication terminal 100 side ends.

  When the exchange 200 receives the location registration information from the mobile communication terminal 100 (step S409), the exchange 200 stores the received location registration information in the terminal information storage unit 251 and also instructs the management device 300 based on the switched telephone number. Registration is requested (step S410).

  In this case, the management apparatus 300 registers the location information in the telephone number after switching by performing the same processing as the above-described steps S111 to S114 (see FIG. 10), and transmits a registration completion notification to the exchange 200. .

  When receiving the registration completion notification from the management apparatus 300 (step S411), the exchange 200 returns to the incoming call process flow shown in FIG. In this case, the number switching processing unit 245 instructs the terminal request unit 225 to transmit an incoming call request using the telephone number after switching. In this case, the terminal request unit 225 accesses the relay processing information storage unit 252, acquires the caller telephone number information and the requested telephone number information recorded in the record of the corresponding incoming call request ID, and deletes the record To do.

  In the flow of incoming processing, the incoming request from the external terminal is relayed to the mobile communication terminal 100 (step S209), and the processing ends. In this case, the terminal request unit 225 accesses the terminal information storage unit 251 and acquires location information associated with the requested telephone number acquired from the relay processing information storage unit 252. The transmission control unit 222 makes a call to the mobile communication terminal 100 via the base station 25 indicated by the position information, so that mobile communication is performed using the requested telephone number (that is, the switched current standby number). Connect to the terminal 100. That is, in the example of the present embodiment, the communication path between the exchange 200 and the mobile communication terminal 100 is established using the private telephone number of the mobile communication terminal 100. The terminal request unit 225 transmits an incoming call request to the mobile communication terminal 100 through the established communication path with the mobile communication terminal 100. Thereby, the incoming call request from the external terminal to the mobile communication terminal 100 is relayed by the exchange 200. In this case, it is transmitted to the mobile communication terminal 100 as a normal incoming call request.

  The operation of the mobile communication terminal 100 that has received the incoming request relay by the exchange 200 will be described below. The terminal incoming call processing executed by the mobile communication terminal 100 in this case will be described with reference to the flowchart shown in FIG.

  This terminal incoming processing is started when the reception control unit 123 of the mobile communication terminal 100 receives an incoming request relayed by the exchange 200. When the mobile communication terminal 100 receives the incoming request, a communication path between the external terminal and the mobile communication terminal 100 is established via the exchange 200. The reception control unit 123 inputs the received incoming request to the control unit 110. When the incoming request analysis unit 112 determines that the incoming request is a normal incoming request, the incoming request analysis unit 112 instructs the voice processing unit 150 to execute an incoming operation. In this case, the voice processing unit 150 performs a predetermined incoming operation such as outputting a ringtone, for example (step S501).

  A user of the mobile communication terminal 100 operates the operation unit 130 to establish a voice call between the external terminal and the mobile communication terminal 100, and a voice call is performed by the operation of the voice processing unit 150 (step S502).

  When the user operates the operation unit 130 to instruct the end of the voice call, the voice processing unit 150 inputs that fact to the control unit 110. In this case, when the telephone number processing unit 113 determines that the call has ended based on the input from the voice processing unit 150 (step S503: Yes), the telephone number information storage area 181 is accessed and the automatic switching flag is turned on. It is determined whether or not (step S504).

  If the automatic switching flag is not ON (step S504: No), the telephone number used for the voice call in step S502 is not a standby number by automatic switching, and thus the process ends. That is, the standby state with the telephone number is maintained.

  On the other hand, when the automatic switching flag is ON (step S504: Yes), the telephone number processing unit 113 returns the telephone number before switching to the standby number based on the automatic switching flag. In this case, for the pre-switching telephone number in which only the automatic switching flag is ON, the standby identification flag is turned ON (step S505), and the automatic switching flag is turned OFF (step S506). For the switched telephone numbers for which both the standby identification flag and the automatic switching flag are on, the standby identification flag is turned off (step S507) and the automatic switching flag is turned off (step S508). Thereby, when the telephone number before switching is returned to the standby number, the location registration for the standby number is performed (step S509). That is, the location registration is performed in the exchange 200 and the management device 300 by the same operation as the location registration operation described above, and the process ends.

  As described above, by applying the present invention as in the above embodiment, it is possible to achieve both the operation efficiency and convenience of the mobile communication terminal. That is, in a mobile communication terminal that can use a plurality of telephone numbers, the power consumption of the mobile communication terminal is reduced by placing any one telephone number in a standby state. If there is an incoming call, a specific caller can switch the standby number to receive the incoming call. For example, emergency calls from family members can be received even in a non-standby state. . In addition, when the standby number is switched exceptionally in this way, the standby number is automatically restored at the end of the call, so that the standby number is switched only when there is a specific incoming call. As a result, it is possible to prevent the phone number that should originally be in the non-standby state from being switched to the standby state, and from a specific source without interfering with the usage form for properly using the phone number. You can only make calls.

  The said embodiment is an example and the application range of this invention is not restricted to this. That is, various applications are possible, and all embodiments are included in the scope of the present invention.

  For example, in the above embodiment, the exchange 200 and the management apparatus 300 are independent of each other, and the standby number of the mobile communication terminal 100 is switched by their cooperation. However, the exchange 200 and the management apparatus 300 are configured integrally. May be.

  Further, in the above embodiment, the case where a call is made from an external terminal to the mobile communication terminal 100 is illustrated, but even if the call is made from another mobile communication terminal 100 to the mobile communication terminal 100, the above implementation is performed. The standby number may be automatically switched by the same processing as that of the embodiment.

  In the mobile communication terminal 100 in the above embodiment, one telephone number is stored in the fixed information storage unit 170 and a plurality of telephone numbers can be used by attaching the IC card 161. A plurality of telephone numbers may be made available only by mounting the IC card 161 without storing the telephone numbers. In this case, by configuring the card interface 160 so that a plurality of IC cards 161 can be mounted at the same time, any one of the telephone numbers stored in each IC card 161 can be used as a standby state. In addition, a plurality of telephone numbers may be registered in one IC card 161. In this case, a plurality of telephone numbers stored in one IC card 161 attached to the mobile communication terminal 100 are used. It may be available.

  Further, in the above embodiment, when the standby number of the mobile communication terminal 100 is automatically switched by a request from the exchange 200, the original telephone number is automatically waited at the end of the call with the telephone number after the switching. Although it is assumed that the serial number is restored, such an operation need not be performed. In this case, for example, the mobile communication terminal 100 may operate to output a message indicating that the standby number has been switched by automatic switching to notify the user at the end of the call.

  It should be noted that, as in the above-described embodiment, it is desirable that an incoming call with a non-standby number can be exceptionally made only when a call is made from a specific caller, based on a password entered by the caller. Alternatively, the standby number may be automatically switched without performing authentication with a password.

  Further, as the information indicating whether or not the telephone number registered in the management apparatus 300 is in the standby state, the position information is used in the above embodiment, but whether each telephone number is in the standby state or not in the standby state. Any information can be used as long as it can be identified whether it is in a state, not limited to position information.

  Note that, as the mobile communication terminal 100 described above, an existing mobile communication terminal that does not have these functions can be provided as well as a mobile communication terminal that has functions for realizing the present invention in advance. The program can be applied to the mobile communication terminal according to the present invention. In this case, at least a mobile communication terminal having a function capable of using a plurality of telephone numbers is applied with a program for causing the mobile communication terminal 100 to execute each process, and the mobile communication terminal A computer (such as a CPU) that controls the computer executes the program, thereby functioning as a terminal device according to the present invention.

  Similarly, the management apparatus 300 can be configured by a dedicated apparatus, and a program for realizing each function of the management apparatus 300 can be applied to a general-purpose computer apparatus (such as a personal computer). Such a management apparatus can be realized.

  The application method of such a program is arbitrary. For example, the program can be applied to an arbitrary device by providing it via a communication medium such as the Internet, and a predetermined recording medium (for example, a memory card, a CD-ROM, a DVD, Etc.) can also be applied by storing and distributing the program.
