Embodiment Construction

[0031] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] The design principle of the method of the present invention: expand a small application program (APPLET) script application on the SIM / USIM card, use a special provision of local information (PROVIDE LOCALINFORMATION) interface to realize the judgment of the transferred information of the mobile device, thereby realizing SIM / USIM USIM cards can only be used on request to specific mobile devices. The Applet application can be implemented through a SIM / USIM card embedded card operation system (COS) customized according to the operator's requirements, and is solidified in the SIM / USIM card when it is issued.

[0033] The PROVIDE LOCAL INFORMATION interface is stipulated by the 3GPP protocol. It is a dedicated interface for the card to request the terminal to provide current local information to the SIM / USIM card. It is one of ...

Abstract

The method includes steps: step 101, initializing SIM / USIM card; step 102, running small application program codes embedded in SIM / USIM card, and obtaining solidified international mobile device ID code from mobile device; step 103, reading script file of small application program embedded in SIM / USIM card, and comparing it with the obtained information of international mobile device ID code; based on matched and checked result to determine whether the subsequent authorization interactive program is gong to be executed or not. Comparing with prior art, the method possesses features of simple operation, easy of implementation, no need of additional equipment. The invention also let mobile device compatible to other SIM / USIM cards.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing locking of a SIM / USIM card to a special terminal. Background technique [0002] With the development of mobile communication technology, the competition between operators is becoming more and more fierce. By subdividing the user market and adopting different marketing strategies for different applications, it has become the direction of future mobile terminal technology development, providing users with different Providing different tariff rates while providing personalized and personalized services has become the focus of consideration for operators to launch new services. As a mobile terminal, whether it is a suitable access device allowed by the network, or the network operator wants to give the device specific functions, so it becomes a requirement to realize the interlocking of the SIM / USIM card and the mobile device. [0003] As the identification carrier o...
