  Next, when temporary registration is performed in the temporary registration process, the temporary registration unit 332 transmits a temporary registration notification signal for notifying that temporary registration has been performed to the mobile terminal 2 via the server communication unit 31 ( Step S106).

  Next, when receiving the temporary registration notification signal from the server 3 via the terminal communication unit 21, the first transmission unit 261 of the portable terminal 2 displays on the display unit 23 that temporary registration has been performed. The second transmission unit 262 is used for removing the foreign SIM card 201 from the mounting unit 24 by the user, inserting the domestic SIM card 202 instead, and further using the domestic SIM card 202 using the operation unit 22. Wait until network settings are input (step S107). The network settings are settings such as an access point name (ESSID, Extended Service Set Identifier), a user name, and a password for the mobile terminal 2 to access the network 6 using the domestic SIM card 202.

  Next, when the network setting is input by the user with the domestic SIM card 201 inserted into the mounting unit 24, the second transmission unit 262 sends a registration request signal to the server 3 via the terminal communication unit 21. (Step S108). The registration request signal is a signal for requesting permission to use the domestic network 6 by the mobile terminal 2 in which the domestic SIM card 202 is inserted. The registration request signal includes the MSN and IMSI assigned to the domestic SIM card 202 in addition to the registration code of the domestic SIM card 202. When the domestic SIM card 202 is inserted by the user and the network setting is input, the second transmission unit 262 automatically reads the domestic SIM card 202, and the MSN and IMSI assigned to the domestic SIM card 202. Is included in the registration request signal.

  Next, the second reception unit 333 of the server 3 receives a registration request signal from the mobile terminal 2 via the server communication unit 31. That is, the second receiving unit 333 receives a registration request signal from the mobile terminal 2 in which the domestic SIM card 202 is inserted. The registration unit 334 performs registration processing based on the registration request signal received by the second reception unit 333 (step S109). In the registration process, the registration unit 334 performs registration for permitting use of the network 6 by the domestic SIM card 202 into which the domestic SIM card 202 is inserted. By performing the registration, the mobile terminal 2 can use the network 6, and thereafter, charging associated with the use of the network 6 occurs. Details of the registration process will be described later.

  Next, when performing registration in the registration process, the registration unit 334 transmits a registration notification signal for notifying that registration has been performed to the mobile terminal 2 via the server communication unit 31 (step S110). When the second transmission unit 262 of the mobile terminal 2 receives the registration notification signal from the server 3 via the terminal communication unit 21, the second transmission unit 262 displays on the display unit 23 that the registration has been performed. Thus, the use permission process for the network 6 ends.

  FIG. 7 is a flowchart illustrating an example of the operation of the temporary registration process.

  The operation flow shown in FIG. 7 is executed in step S105 of the operation sequence shown in FIG.

  First, the temporary registration unit 332 extracts the MSN and IMSI assigned to the foreign SIM card 201 and the registration code of the domestic SIM card 202 from the temporary registration request signal received by the first receiving unit 331 ( Step S201).

  Next, the temporary registration unit 332 determines whether or not the extracted registration code of the domestic SIM card 202 is appropriate (step S202). The temporary registration unit 332 determines whether or not the extracted registration code is appropriate based on whether or not the extracted registration code of the domestic SIM card 202 is registered in the SIM card table in advance.

  If the registration code is appropriate, the temporary registration unit 332 determines whether or not the registration code has already been temporarily registered or registered in the state management table (step S203). The temporary registration unit 332 determines whether or not the registration code has already been provisionally registered or registered depending on whether or not the registration code is stored in the state management table and the state of the registration code is provisional registration or registration completion. judge.

  When the registration code has already been provisionally registered or registered, the provisional registration unit 332 ends the series of steps without performing any particular processing.

  On the other hand, if the registration code has not been provisionally registered or registered, the provisional registration unit 332 stores the extracted information in the state management table so that the mobile terminal 2 in which the domestic SIM card 202 is inserted is connected to the network 6. Temporary registration for permitting use is performed (step S204), and a series of steps is completed. The temporary registration unit 332 associates the extracted MSN, IMSI, and registration code and stores them in the state management table, stores temporary registration as a state associated with each stored information, and stores the current time as a temporary registration time. .

  On the other hand, if the registration code is not appropriate in step S202, the temporary registration unit 332 transmits the temporary registration request signal including the inappropriate registration code from the mobile terminal 2 in which the foreign SIM card 201 is inserted. Is greater than or equal to a predetermined number (for example, 5 times) (step S205).

  If the number of times that the temporary registration request signal including an inappropriate registration code is transmitted is less than the predetermined number, the temporary registration unit 332 ends the series of steps without performing any particular processing.

  On the other hand, when the number of times that the temporary registration request signal including the inappropriate registration code is transmitted is equal to or greater than the predetermined number, the temporary registration unit 332 determines that the user of the mobile terminal 2 has malicious intent and The temporary registration by the terminal 2 is set to be restricted (step S206), and a series of steps is finished. For example, the temporary registration unit 332 does not allow temporary registration using the MSN and IMSI included in the temporary registration request signal until a predetermined period (for example, 24 hours) or a predetermined time (for example, 12:00 on the next day). Set.

  As described above, when the first receiving unit 331 receives a registration code that is not registered in the SIM card table together with the MSN and the IMSI assigned to the overseas SIM card 201, the temporary registration unit 332 Restrict temporary registration using MSN and IMSI. Thereby, the temporary registration part 332 can suppress that the domestic SIM card 202 is abused by a malicious user.

  Note that the processing in steps S205 and S206 may be omitted. In that case, the temporary registration unit 332 can permit temporary registration again by a user who has entered the registration code by mistake without having malicious intent.

  FIG. 8 is a flowchart showing an example of the operation of the registration process.

  The operation flow shown in FIG. 8 is executed in step S109 of the operation sequence shown in FIG.

  First, the registration unit 334 extracts the registration code of the domestic SIM card 202 and the MSN and IMSI assigned to the domestic SIM card 202 from the registration request signal received by the second reception unit 333 (step S301). ).

  Next, the registration unit 334 determines whether or not the extracted registration code of the domestic SIM card 202 is provisionally registered (step S302). The registration unit 334 determines whether the extracted registration code matches the registration code stored in the state management table and whether the registration code is temporarily registered. It is determined whether or not provisionally registered.

  When the extracted registration code is provisionally registered, the registration unit 334 determines whether or not the extracted MSN and IMSI are appropriate (step S303). The registration unit 334 determines whether or not the extracted MSN and IMSI are appropriate depending on whether or not the extracted MSN and IMSI match the MSN and IMSI stored in association with the extracted registration code in the SIM card table. Determine.

  When the MSN and the IMSI are appropriate, the registration unit 334 performs registration for permitting the use of the network 6 by the mobile terminal 2 in which the domestic SIM card 202 is inserted (step S304), and ends a series of steps. . In the status management table, the registration unit 334 stores the extracted MSN and IMSI in association with the registration code that matches the extracted registration code, and stores the registration as the status associated with the registration code, as the registration time. Memorize the current time.

  On the other hand, when the registration code is not provisionally registered, or when the MSN and IMSI are not appropriate, the registration unit 334 receives the registration code that is not provisionally registered or the appropriate one from the mobile terminal 2 in which the domestic SIM card 202 is inserted. It is determined whether or not the number of times the registration request signal including the non-MSN and IMSI is transmitted is equal to or greater than the second predetermined number (for example, 5 times) (step S305).

  If the registration request signal including the provisional registration code or the inappropriate MSN and IMSI is less than the second predetermined number of times, the registration unit 334 performs a series of steps without performing any particular processing. finish.

  On the other hand, if the number of times the registration request signal including the registration code that is not temporarily registered or the inappropriate MSN and IMSI is transmitted is equal to or more than the second predetermined number, the registration unit 334 indicates that the user of the mobile terminal 2 has malicious intent. The corresponding temporarily registered information is deleted from the state management table (step S306).

  Next, the registration unit 334 sets so as to restrict registration by the mobile terminal 2 (step S307), and ends a series of steps. For example, the registration unit 334 does not allow temporary registration and registration using the MSN and IMSI included in the registration request signal until a certain period (for example, 24 hours) or a predetermined time (for example, 12:00 on the next day). Set.

  As described above, the registration unit 334 receives the MSN and IMSI that are not registered in the SIM card table in association with the registration code of the domestic SIM card 202 by the second reception unit 333 for the second predetermined number of times or more. If this happens, subsequent registration using the MSN and IMSI is restricted. Thereby, the registration part 334 can suppress that the domestic SIM card 202 is abused by a malicious user.

  Note that the processing in steps S305 to S307 may be omitted. In that case, the registration unit 334 may re-register by a user who has entered the registration code by mistake without malicious intentions, or may have entered the registration code for himself by another user. Registration by registered users can be allowed.

  In addition, the temporary registration unit 332 receives a registration request signal including a registration code that matches the temporarily registered registration code within the predetermined time (for example, 24 hours) after the temporary registration. If not, temporary registration may be invalidated. The temporary registration unit 332 periodically reads the state management table, and determines whether there is a registration code in which a predetermined time has elapsed from the temporary registration time while the state is temporarily registered. The temporary registration unit 332 changes the status of the registration code to unregistered in the status management table when there is a registration code in which the predetermined time has elapsed from the temporary registration time while the status is temporarily registered.

  Accordingly, the temporary registration unit 332 can prevent the registration code from being left as it is temporarily registered, and can prevent the domestic SIM card 202 from being erroneously registered by another user.

  In addition, the provisional registration unit 332 is in a state where the second reception unit 333 does not receive a registration request signal including a registration code that matches the provisionally registered registration code within a predetermined time after the provisional registration. Each piece of temporarily registered information may be deleted from the management table. The temporary registration unit 332 deletes each piece of information associated with the registration code from the state management table when there is a registration code in which the predetermined time has elapsed from the temporary registration time while the state is temporarily registered.

  Thereby, the temporary registration part 332 can delete appropriately the information regarding a user, and can suppress that the information regarding a user leaks.

  As described above, the server 3 is a portable terminal in which the domestic SIM card 202 is inserted on the condition that the IMSI assigned to the overseas SIM card 201 is acquired from the portable terminal 2 that is internationally roamed. 2 to use the domestic network 6. As a result, the communication system 1 can acquire information about the user without allowing a user outside the country to visit a store operated by a domestic telecommunications carrier, and is used when an unexpected situation occurs. Can be contacted. Therefore, the communication system 1 can allow the foreign user to use the domestic network using the domestic SIM card 202 without reducing the convenience of the foreign user. Thereby, the communication system 1 can provide an international roaming service according to the charge setting of a domestic communication carrier to a user outside the country.

  A domestic telecommunications carrier can set an upper limit of a charge amount charged to a user by setting an upper limit of the communication amount allocated to the domestic SIM card 202 or the like. Further, domestic telecommunications carriers can also provide the domestic SIM card 202 in a prepaid manner. Thus, the communication system 1 can provide a flexible service according to the user's needs by providing the international roaming service according to the charge setting of the domestic telecommunications carrier.

  In addition, the server 3 acquires only identification information such as MSN and IMSI assigned by the communication carrier outside the country with which the user subscribes, from the mobile terminal 2, and does not acquire other personal information. Accordingly, the server 3 can prevent personal information of the user of the mobile terminal 2 from leaking.

  In this embodiment, the server 3 stores the MSN and IMSI assigned to the domestic SIM card 202 and the overseas SIM card 201 in association with the registration code of the domestic SIM card 202, respectively. explained. By storing both MSN and IMSI, the user's contact information can be specified more easily, but if only IMSI is stored, the user's contact information can be specified, so MSN is not stored. Also good.

  It should be understood by those skilled in the art that various changes, substitutions and modifications can be made thereto without departing from the spirit and scope of the present invention.
