First, the user operates the input unit 12 to select the automatic information transfer setting menu, and after the mobile terminal 1 becomes unusable, the transfer destination is set when an incoming call or e-mail is received. For the setting, a transfer destination telephone number when a voice call is received, a transfer destination e-mail address when an e-mail is received, and the like can be set. It is also possible to set not to perform automatic transfer. The setting processing unit 17 reads the operation content of the input unit 12 and stores the setting content in the storage unit 14. As a result, the storage unit 14 stores information on the transfer destination telephone number, information on the transfer destination electronic mail address, and the like when automatic transfer is set. When the setting for not performing automatic transfer is selected, setting information indicating that automatic transfer is not performed is stored in the storage unit 14.

  Next, with reference to FIG. 2, an operation when the mobile terminal 1 receives the subscriber specific code erasure request signal from the subscriber information management server 4 in the communication system shown in FIG. 1 will be described. In the mobile terminal 1, it is assumed that the settings relating to downloading of the stored information and the settings relating to the transfer of downloaded information are performed in advance before receiving the subscriber specific code erasure request signal.

  First, for example, when an application for erasure of cellular phone subscriber information is made due to cancellation of a cellular phone contract, the administrator of the subscriber information management server 4 joins the application subscriber's telephone number and subscriber name, etc. The subscriber identification information is input to the subscriber information management server 4. The subscriber management unit 41 determines whether the application for deleting the mobile phone subscriber information is valid based on whether or not the input telephone number and subscriber identification information are stored in the telephone number information storage unit 42. To do. As a result of this determination, if it is recognized as valid, the subscriber management unit 41 requests the mobile terminal 1 having the input telephone number to start deleting the telephone number (subscriber specific code) (OTAPA). A request signal is transmitted (step S1). When the portable terminal 1 receives this request signal via the wireless communication unit 15, the control unit 11 reads setting information regarding information download stored in the storage unit 14. If automatic download (“all reception”) is set, the control unit 11 instructs the communication processing unit 16 to start automatic download of stored information (step S2). In response to this, the communication processing unit 16 connects to the user information management server 5 (e-mail server function) (step S3), and transmits an e-mail data download request including the telephone number assigned to the portable terminal 1. To do. In response to this, the information management unit 51 reads the e-mail data associated with the telephone number included in the e-mail data download request from the user information storage unit 52 and transmits it to the mobile terminal 1 to download it. Is executed (step S4). The communication processing unit 16 receives the e-mail data via the wireless communication unit 15 and stores the received data in the storage unit 14.

  Next, the communication processing unit 16 connects to the user information management server 5 (answering memo accumulating server function) (step S5), and makes a request for downloading the recorded memo data including the telephone number assigned to the portable terminal 1. Send. In response to this, the information management unit 51 reads out the recorded message memo data associated with the telephone number included in the recorded message memo data download request from the user information storage unit 52 and transmits it to the mobile terminal 1. The download is executed (step S6). The communication processing unit 16 receives the recorded message memo data via the wireless communication unit 15 and stores the received data in the storage unit 14.

  Next, the communication processing unit 16 connects to the user information management server 5 (schedule server function) (step S7), and transmits a schedule data download request including the telephone number assigned to the mobile terminal 1. In response to this, the information management unit 51 reads the schedule data associated with the telephone number included in the schedule data download request from the user information storage unit 52 and transmits it to the mobile terminal 1 to execute the download. (Step S8). The communication processing unit 16 receives the schedule data via the wireless communication unit 15 and stores the received data in the storage unit 14.

  Next, the communication processing unit 16 verifies whether or not the executed download has been completed normally. If the download has not been completed normally, the communication processing unit 16 executes the download again (step S9). The communication processing unit 16 notifies the control unit 11 that the download has been completed. In response to this, the control unit 11 reads setting information related to automatic information transfer stored in the storage unit 14. If automatic transfer is set, the control unit 11 instructs the setting processing unit 17 to perform setting registration regarding automatic transfer (step S10). In response to this, the setting processing unit 17 reads out the voice incoming call transfer destination telephone number and the telephone number of the portable terminal 1 stored in the storage unit 14 and passes them to the communication processing unit 16. The communication processing unit 16 transmits a transfer destination telephone number registration request including the voice incoming transfer destination telephone number and the telephone number of the portable terminal 1 to the user information management server 5 (step S11). In response to this, the information management unit 51 associates the voice incoming transfer destination telephone number included in the transfer destination telephone number registration request with the telephone number of the portable terminal 1 and registers it in the user information storage unit 52, and carries a completion notification. It transmits to the terminal 1 (step S12).

  Next, the setting processing unit 17 reads the e-mail transfer destination address and the telephone number of the mobile terminal 1 stored in the storage unit 14 and passes them to the communication processing unit 16. The communication processing unit 16 transmits an e-mail transfer destination address registration request including the e-mail transfer destination address and the telephone number of the portable terminal 1 to the user information management server 5 (step S13). In response to this, the information management unit 51 associates the e-mail transfer destination address included in the e-mail transfer destination address registration request with the telephone number of the portable terminal 1 and registers it in the user information storage unit 52, and sends a completion notification to the mobile phone. It transmits to the terminal 1 (step S14).

  Next, upon receiving notification of completion of setting registration relating to automatic transfer, the control unit 11 connects to the subscriber information management server 4 and requests the start of erasing the telephone number (step S15). The person manager 41 starts the processing for deleting the telephone number. The telephone number erasure processing operation will be described later.

  Next, with reference to FIG. 3, the detailed operation when the mobile terminal 1 shown in FIG. 1 executes the sequence operation shown in FIG. 2 will be described. First, when the control unit 11 receives a request signal (signal message) via the wireless communication unit 15 (step S21), the received request signal requests that the telephone number (subscriber specific code) deletion (OTAPA) start be requested. It is determined whether or not it is a signal (step S22), and if it is a request signal for requesting the start of erasing the telephone number, the setting contents related to information download stored in the storage unit 14 are read (step S23), and automatic download is performed. It is determined whether it is set (step S24). If automatic download is set, the control unit 11 sounds a download start sound for notifying the start of download (step S27). If it is determined in step S22 that the request is not for deleting a telephone number, the process returns to step S21.

  On the other hand, if automatic download is not set, the fact that a request signal for requesting the start of deletion of telephone number (subscriber specific code) (OTAPA) is held inside and waiting until the user performs an operation. The control unit 11 reads the operation content of the input unit 12 (step S25). Then, the control unit 11 determines whether or not this operation content is an operation for instructing to start the automatic download of the stored information (step S26). If the operation content is an instruction to start the automatic download, the automatic download is performed. To start. If the input operation content read in step S25 is not an operation for instructing to start automatic download, the process returns to step S25 and the same processing is repeated.

  When automatic download is set and a download start sound is sounded or when an automatic download start instruction is given, the control unit 11 instructs the communication processing unit 16 to start automatic download of stored information. . In response to this, the communication processing unit 16 connects to the user information management server 5 and downloads e-mail data, recorded message memo data and schedule data (step S28; steps S3 to S8 shown in FIG. 2). Each data is stored in the storage unit 14.

  Next, the communication processing unit 16 confirms the execution status of the executed download (step S29), and determines whether the download is successful (step S30). If the download is not successful, the communication processing unit 16 notifies the control unit 11 that the download was not successful. In response to this, the control unit 11 displays on the display unit 13 that the download was not successful, displays a message asking whether to execute the download again (step S32), and responds to the inquiry from the input unit 12 Is read. Then, the content of the read answer is determined (step S33), and if it is an answer to be executed again, the process returns to step S28 to download again.

  Next, when the download is successful and when an answer that the download fails and is not executed again is input, the control unit 11 reads the setting information related to the automatic information transfer stored in the storage unit 14 (step S31). It is determined whether or not automatic transfer is set (step S34). If automatic transfer is set, the control unit 11 instructs the setting processing unit 17 to perform setting registration regarding automatic transfer. In response to this, the setting processing unit 17 sets and registers transfer destination information in the user information management server 5 (step S35; steps S11 to S14 shown in FIG. 2).

  Next, when receiving a notification of completion of setting registration relating to automatic transfer from the user information management server 5, the control unit 11 connects to the subscriber information management server 4 and requests to start erasing the telephone number (step S15). In response to this, the subscriber management unit 41 starts a processing operation for deleting a telephone number (subscriber information) (step S36). If automatic transfer is not set, connection to the subscriber information management server 4 is performed without requesting registration of transfer destination information, and a request to start deleting the telephone number is made.

  Next, with reference to FIG. 4, the processing operation for deleting the telephone number (subscriber information) will be described. First, upon receiving a notification of completion of setting registration relating to automatic transfer from the user information management server 5, the control unit 11 instructs the communication processing unit 16 to start a processing operation for deleting a telephone number (subscriber information). . In response to this, the communication processing unit 16 transmits a packet for requesting the start of the telephone number (subscriber information) deletion processing operation (step S41). In response, the subscriber information management server 4 establishes service negotiation with the mobile terminal 1 (step S42). Then, the subscriber information management server 4 executes PPP authentication and SSL authentication with the mobile terminal 1 (step S43).

  When the authentication for performing information communication between the subscriber information management server 4 and the mobile terminal 1 is completed, the subscriber management unit 41 executes the authentication process of the mobile terminal 1 accompanying the process of deleting the telephone number (subscriber information). (Step S44). When terminal authentication is completed, the subscriber management unit 41 notifies the mobile terminal 1 that terminal authentication has been completed. In response to this, the control unit 11 instructs the communication processing unit 16 to make a subscriber information (subscriber specific code) download request to the subscriber information management server 4. In response to this, the communication processing unit 16 subscribes a subscriber information download request including the telephone number of the mobile terminal 1 in order to initialize the subscriber information (subscriber specific code) stored in the storage unit 14. Is transmitted to the person manager 41 (step S45). In response, the subscriber management unit 41 transmits an initial value of subscriber information (for example, “01234567” or the like) to the mobile terminal 1 (step S46).

  The communication processing unit 16 initializes the subscriber information stored in the storage unit 14 by overwriting the initial value of the subscriber information transmitted by the subscriber management unit 41 in the storage unit 14 (step S47). Then, the communication processing unit 16 transmits a subscriber information writing completion report indicating that the subscriber information has been initialized to the subscriber management unit 41 (step S48). In response to this, the subscriber management unit 41 executes subscriber information writing completion report processing by deleting the phone number information to be deleted stored in the phone number information storage unit 42 (step S49). Communication with the portable terminal 1 is disconnected (step S50). As a result, the subscriber information stored in the storage unit 14 is erased and returned to the initial value, and thereafter the portable terminal 1 cannot be used.

  In addition, when deletion of mobile phone subscriber information is applied, and the subscriber information management server 4 transmits a request signal for requesting the start of deletion of telephone number (subscriber specific code) (OTAPA) to the mobile terminal 1 In addition, this request signal may be ignored for a certain period of time depending on the setting of the input operation by the user. In this way, it is possible to use the mobile terminal 1 whose mobile phone subscriber information is to be erased for a certain period of time in an emergency or the like. However, when the request signal is set to be ignored by the user for a certain period of time, and the subscriber information management server 4 transmits a request signal for requesting the start of deletion of the telephone number (subscriber specific code) (OTAPA) again after a certain period of time has elapsed. The setting for ignoring the request signal set by the user for a certain period is invalid.

  As described above, since the information stored in the user information management server is downloaded before the mobile phone subscriber information is deleted, the stored information can be reliably protected. In addition, since the destination of voice incoming call and email reception after the mobile terminal 1 becomes unusable is set before deleting the mobile phone subscriber information, the voice incoming call and email can be transferred without omission. Is possible. In addition, since information download and transfer destination setting are automatically performed, it is possible to reduce the time and effort of the user.
