  FIG. 6 is a diagram illustrating an example of an operation flow of program update processing of the mobile terminal 2 by the terminal processing unit 210. The operation flow described below is executed mainly by the terminal processing unit 210 in cooperation with each element of the mobile terminal 2 based on a program stored in the terminal storage unit 204 in advance.

  First, the terminal control unit 211 determines whether or not the terminal communication unit 201 has received an installation request signal from the SMS transmission server 5, that is, from the update server 3 via the SMS transmission server 5 (step S301).

  If the terminal communication unit 201 has not received an installation request signal from the SMS transmission server 5 (No at Step S301), the terminal control unit 211 does not perform any particular process and moves the process to Step S306.

  On the other hand, when the terminal communication unit 201 receives the installation request signal from the SMS transmission server 5 (step S301-Yes), the terminal control unit 211 is included in the installation request signal to the update server 3 via the terminal communication unit 201. The acquisition of a program group corresponding to the program ID is requested (step S302). The terminal control unit 211 requests acquisition of a program group by accessing a URL included in the installation request signal, for example, according to an HTTP protocol.

  When the terminal communication unit 201 receives an installation request signal from the SMS transmission server 5, the terminal control unit 211 automatically requests the update server 3 to acquire a program group. When the terminal communication unit 201 receives an installation request signal from the SMS transmission server 5, the terminal control unit 211 displays a message to that effect on the display unit 203, and the user gives an installation instruction using the operation unit 202. In some cases, the update server 3 may be requested to acquire a program group.

  Next, the terminal control unit 211 waits until the requested program group is received via the terminal communication unit 201 (step S303).

  Next, when the requested program group is received via the terminal communication unit 201 (Yes in step S303), the terminal control unit 211 stores the received program group in the terminal storage unit 204 so as to be usable (step S304). .

  Next, the terminal control unit 211 stores, in the program management table of the terminal storage unit 204, a list of programs constituting the program group stored in the terminal storage unit 204 (Step S305). The terminal control unit 211 stores the program ID and the program name included in the installation request signal in a list of programs associated with the service ID included in the installation request signal.

  Next, the terminal control unit 211 determines whether or not the terminal communication unit 201 has received an uninstallation request signal from the SMS transmission server 5, that is, from the update server 3 via the SMS transmission server 5 (step S306). .

  When the terminal communication unit 201 has not received the uninstallation request signal from the SMS transmission server 5 (step S306-No), the terminal control unit 211 proceeds to step S301 without performing any particular process, and again performs step S301. The subsequent processing is repeated.

  On the other hand, when the terminal communication unit 201 receives an uninstall request signal from the SMS transmission server 5 (Yes in step S306), the terminal control unit 211 stores a program group corresponding to the program ID included in the uninstall request signal in the terminal. It deletes from the part 204 (step S307).

  Next, the terminal control unit 211 deletes the program group deleted from the terminal storage unit 204 from the program list in the program management table of the terminal storage unit 204 (step S307). The terminal control unit 211 deletes the program ID and program name included in the uninstallation request signal stored in the program management table in association with the service ID included in the uninstallation request signal. Next, the terminal control part 211 transfers a process to step S301, and repeats the process after step S301 again.

  FIG. 7 is a diagram illustrating an example of an operation flow of the program monitoring process of the mobile terminal 2 by the terminal processing unit 210. The operation flow described below is executed mainly by the terminal processing unit 210 in cooperation with each element of the mobile terminal 2 based on a program stored in the terminal storage unit 204 in advance.

  First, the terminal monitoring unit 212 starts measuring time for determining whether a predetermined time (for example, one hour) has elapsed (step S401).

  Next, the terminal monitoring unit 212 extracts, for all service IDs stored in the program management table, program IDs in a program list stored in association with each service ID in the program management table (step S402). ).

  Next, the terminal monitoring unit 212 determines whether or not the program corresponding to each extracted program ID has been deleted in the terminal storage unit 204 (step S403).

  If the program corresponding to each extracted program ID has not been deleted (step S403-No), the terminal monitoring unit 212 proceeds to step S405 without performing any particular process.

  On the other hand, if the program corresponding to each extracted program ID has been deleted (Yes in step S403), the terminal monitoring unit 212 sends an acquisition request signal for requesting acquisition of the deleted program via the terminal communication unit 201. Is transmitted to the update server 3 (step S404). The acquisition request signal includes the terminal ID and address information of the mobile terminal 2, the program ID and program name of the program requesting acquisition, the service ID and service name corresponding to the program ID, and the like.

  In addition, when the update server 3 receives the acquisition request signal from the mobile terminal 2, whether the terminal ID included in the acquisition request signal is stored in the terminal management table in association with the service ID, and the program ID is the service ID. It is determined whether it is associated and stored in the program management table. The update server 3 stores the program corresponding to the program ID when the terminal ID is stored in the terminal management table in association with the service ID, and the program ID is stored in the program management table in association with the service ID. A program installation request is transmitted to the portable terminal 2. The portable terminal 2 installs the program received from the update server 3 in accordance with the program update process shown in FIG.

  Next, the terminal monitoring unit 212 determines whether or not a predetermined time has elapsed since the start of time measurement (step S405).

  If the predetermined time has not elapsed since the start of timing, the terminal monitoring unit 212 returns the process to step S403 and repeats the processes of steps S403 to S404. On the other hand, when a predetermined time has elapsed since the start of time measurement, the terminal monitoring unit 212 returns the process to step S401 and starts time measurement again. In this way, the terminal monitoring unit 212 periodically monitors whether or not a program in the program list of the program management table has been deleted.

  By operating according to the flowchart shown in FIG. 7, even if the user of the mobile terminal 2 accidentally deletes the program necessary for receiving the service provision, the program is automatically reinstalled, and the mobile terminal The second user can continue to receive the service smoothly.

  Note that the terminal monitoring unit 212 does not regularly monitor whether or not the program is deleted, but when the program is deleted by the user of the mobile terminal 2, the program is managed in the program management table. You may determine whether it is a program. In this case, when the program is deleted by the user of the mobile terminal 2 using the operation unit 202, the terminal monitoring unit 212 stores the program ID of the program in association with each service ID in the program management table. It is determined whether or not it matches any one of the program IDs in the list. If the program ID matches any one of the program IDs in the list, the terminal monitoring unit 212 transmits an acquisition request signal for the deleted program to the update server 3 via the terminal communication unit 201.

  As described above, when the update server 3 receives the subscription information signal or the cancellation information signal from the user management server 7, the update server 3 carries the program group corresponding to the service and the installation request signal or the uninstallation request signal of the program group. Transmit to terminal 2. On the other hand, the mobile terminal 2 adds or deletes the program group according to the installation request signal or the uninstall request signal received from the update server 3. Thereby, a program group necessary for providing each service is automatically installed when the user of the mobile terminal 2 subscribes to the service, and is automatically uninstalled when the service is canceled. Therefore, the program group corresponding to the service subscribed to by the user can be updated easily and appropriately in the portable terminal 2.

  A program group necessary for providing each service is automatically installed when the user of the portable terminal 2 subscribes to the service, and is automatically uninstalled when the service is canceled. Therefore, the mobile terminal 2 updates whether or not the user of the mobile terminal 2 subscribes to the service every time each program executes a process for executing each service or charges each service. There is no need to make an inquiry to the server 3 or the user management server 7. Therefore, it is possible to reduce the processing load and the communication amount of the mobile terminal 2, the update server 3, and the user management server 7.

  The update server 3 transmits a program group and an installation request signal to the mobile terminal 2 only when the terminal ID and address information of the mobile terminal 2 are not stored in the terminal management table in association with the service ID. Furthermore, the update server 3 transmits an uninstall request signal to the mobile terminal 2 only when the terminal ID and address information of the mobile terminal 2 are associated with the service ID and stored in the terminal management table. Thereby, the user management terminal 6 transmits the service subscription signal or the service cancellation signal to the user management server 7 in a duplicate, and the user management server 7 transmits the subscription information signal or the cancellation information signal to the update server 3 in a duplicate. However, the update server 3 does not transmit the program group and the installation request signal or the uninstall request signal to the portable terminal 2 in duplicate. Therefore, it becomes possible to reduce the processing load and communication amount of the portable terminal 2 and the update server 3.

  Note that the present invention is not limited to this embodiment. For example, the SMS generation server 4 and the SMS transmission server 5 may be omitted in the communication system 1. In that case, the update server 3 has the functions of the SMS generation server 4 and the SMS transmission server 5, and transmits the SMS message directly to the mobile terminal 2.

  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.
