JP5530390B2 - Universal subscriber identification module (USIM) and USIM-led service implementation method - Google Patents

Description

  The present invention relates to a universal subscriber identification module (USIM) and a USIM-driven service realization method that enables a communication service to be used by being mounted on a mobile terminal.

  When using a mobile phone terminal, a universal subscriber identity module (USIM) containing a telephone number and network information is attached to the terminal. In Japan, it is common that mobile phone terminals can only use USIMs of specific business operators. This state is called SIM lock. Recently, however, SIM lock-free terminals, that is, terminals that are not SIM-locked, have been increasing, and operators have controlled their networks, mobile devices (MEs), and USIMs, and provided their own services. Is becoming difficult to provide. As a means for solving such a problem, there is a standard specification called a USAT (USIM Application Toolkit) function defined in 3GPP (3rd Generation Partnership Project) TS31.111 (Non-Patent Document 1). According to the USAT function, it is possible for the USIM to instruct the terminal to perform an operation in response to a command issued from the network.

3GPP TS 31.111

  When the USIM uses a means for instructing the terminal to perform an operation, the conventional USAT function requires a command to be issued from the network, so that not only the USIM but also a network server needs to be added. For this reason, the number of man-hours is large, and this is a big barrier to realization.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a universal subscriber identification module (USIM) and a service implementation method led by a USIM that can provide a service unique to an operator to the terminal simply by being attached to a SIM lock-free terminal. It is to be realized simply and at low cost.

  The general-purpose subscriber identification module (USIM) of the present invention is a USIM that is mounted on a USAT function compatible terminal that is not SIM-locked, a database in which a list of terminal identification information is stored in advance, As an opportunity, information acquisition means for acquiring terminal identification information from the terminal, information verification means for checking the terminal identification information acquired by the information acquisition means with the list, and terminal identification information acquired by the information acquisition means in the list Command issuing means for issuing a predetermined proactive command to the terminal when not included.

  According to the universal subscriber identification module (USIM) and the service implementation method led by the USIM of the present invention, the USIM can instruct the operation of the terminal in a simple and low cost manner by adding a function only to the USIM. Is possible. Therefore, it is possible to provide a service unique to the operator only by attaching the USIM of the present invention to the SIM lock-free terminal.

The figure which shows the structural example of a universal subscriber identification module (USIM) 100. The figure which shows the example of a processing flow of a universal subscriber identification module (USIM) 100. The figure which shows the example of the whole sequence of the service implementation method led by USIM.

  FIG. 1 shows a configuration example of a universal subscriber identification module (USIM) 100 of the present invention, and FIG. 2 shows a processing flow example in a service realization method using the same.

  The universal subscriber identification module (USIM) 100 is a USIM attached to the terminal 10 that is not SIM-locked, and includes a database 110, an information acquisition unit 120, an information collation unit 130, and a command issue unit 140. The terminal 10 is assumed to have a USAT function defined by 3GPP TS 31.111.

  The database 110 stores in advance a list of terminal identification information of terminals that do not require software update when providing a service unique to the operator. As terminal identification information, for example, IMEI (International Mobile Equipment Identity) can be used.

  The information acquisition unit 120 acquires terminal identification information from the terminal 10 when triggered by energization from the terminal 10 or reception of a USIM internal file read command at the time of terminal activation specified by a standard such as 3GPP or ETSI (S1). ).

  The information collating unit 130 collates whether or not the terminal identification information acquired by the information acquiring unit 120 is included in the list. If the terminal identification information is included in the list, it is not necessary to update the software when providing the service unique to the operator. If it is not included in the list, the command issuing means 140 is notified of this (S2).

  When the command issuing unit 140 receives a notification from the information collating unit 130 that the terminal identification information acquired by the information acquiring unit 120 is not included in the list, the command issuing unit 140 outputs a predetermined proactive command defined in 3GPP TS 31.111. It is issued to the terminal (S3).

  FIG. 3 shows an example of the entire sequence of the service realization method led by the universal subscriber identification module (USIM) 100 of the present invention. When the terminal 10 is activated, the location of the terminal 10 is registered in the network 20 and the universal subscriber identification module (USIM) 100 is energized, and the information acquisition unit 120 receives the terminal identification information from the terminal 10 in response to this. Obtain (S1). Subsequently, the information collating unit 130 collates with the list (S2), and if the acquired terminal identification information is not in the list, the command issuing unit 140 issues a proactive command (Displaytext, GetInkey, etc.) to the terminal 10 ( S3). In response to this, the terminal 10 displays a dialog such as “Do you want to set up the operator? Yes / No” on the terminal, and if the user selects “Yes”, the command issuing means 140 again A proactive command (LaunchBrowser etc.) is issued to the terminal 10. In response to this, the terminal 10 activates the browser, connects to the operator designated site, and displays the screen. Then, when the user selects the service content displayed on the screen, an application for the operator service is collectively installed from the network 20 to the terminal 10.

  As described above, according to the universal subscriber identification module (USIM) 100 and the service implementation method led by the USIM according to the present invention, the USIM leads the terminal easily and at low cost by adding the function only to the USIM. The operation can be instructed. For this reason, it is possible to provide a service unique to an operator only by attaching the USIM of the present invention to a SIM lock-free terminal.

  Note that it is desirable that the list of terminal identification information in the database 110 be updated sequentially as new terminals are announced one after another and functions may be added to already distributed terminals. Therefore, for example, an updating unit 150 that periodically gives the command issuing unit 140 an instruction for causing the command issuing unit 140 to issue a command for causing the terminal 10 to make an inquiry to update the list to the network 20 is added. A method of updating the list of the database 110 with the list is conceivable. Further, when the information collating unit 130 determines that the terminal identification information is not included in the list stored in the database 110, the command issuing unit 140 makes a command for causing the terminal 10 to inquire the network 20 about the list update. It is possible to add a function to be issued. In this case, if an update list is obtained as a result of issuing an update inquiry command (S4), the list of the database 110 is updated accordingly (S5). Then, the information matching unit 130 determines again whether or not the terminal identification information acquired by the information acquisition unit 120 is included in the list. If the terminal identification information is included in the list, the process is terminated. If not, the command issuing unit 140 is notified of this (S2), and the command issuing unit 140 issues a predetermined proactive command to the terminal (S3). On the other hand, if the update list is not obtained, a predetermined proactive command is issued to the terminal (S3).

  The function sharing and processing procedure of the constituent elements of the universal subscriber identification module (USIM) 100 of the present invention described above are not limited to the above function sharing and processing procedure, and are appropriately set within the scope not departing from the present invention. It can be changed.
