Instance one
Fig. 4 is the detailed process flow chart according to the cipher processing method of the portable terminal of method shown in Figure 3, and is as shown in Figure 4, comprises following processing.
Step S401, user's start;
Step S402, control module at first extracts data and the ESN at terminal itself in the memory module in the terminal, with the terminal iidentification be below ESN be example the present invention will be described, the ESN that we suppose to read out this moment the terminal is " 12345678 ";
Step S403, whether two data among the control module meeting determining step S402 are consistent, if the two data consistent then enters into step S404, otherwise enter into step S406;
Step S404; The data of preserving in the memory module of supposing to read out this moment are " 12345678 "; The data that are memory module are consistent with terminal ESN; Explain that this terminal also to set up binding relationship with any card at present, bindings will be carried out in the terminal, promptly set up binding relationship to the card and this terminal that are inserted in this terminal this moment.Particularly; Control module can read out the IMSI of Subscriber Identity Module, and (ident value of Subscriber Identity Module is not unique; The present invention is that example describes with IMSI); The IMSI value that our hypothesis reads out is " 460030925477888 ", and control module writes it in memory module afterwards, original data in the replacement memory module; The data of preserving in the memory module afterwards become the IMSI value that be inserted in this Subscriber Identity Module in the terminal this moment, and so far bindings (corresponding above-mentioned step S302) has been accomplished at the terminal;
Step S405, the data in the memory module have become " 460030925477888 " by " 12345678 ", so the relation of binding has just been set up with the card that is inserted in this moment in this terminal in this terminal, proceed to step S407;
Step S406: the data of preserving in the memory module of supposing to read out this moment are " 460030925477888 "; Be memory module and data and terminal ESN: " 12345678 " are inconsistent; Explain that this terminal set up binding relationship with a card before this starts; IMSI value that card is corresponding is " 460030925477888 ", and next control module can read out the IMSI that is inserted in the Subscriber Identity Module in the terminal at this moment, and the IMSI that preserves in itself and the memory module is compared; If the IMSI value that this moment, we read out from card is: " 460030925477666 "; This value is inconsistent with the IMSI value " 460030925477888 " that reads out from memory module, and explanation card at this moment is not that card of setting up binding relationship originally with this terminal so, enters into step S408; If the IMSI value that this moment, we read out from card is: " 460030925477888 "; This value is consistent with the IMSI value " 460030925477888 " that reads out from memory module; With regard to explanation card at this moment is that card of setting up binding relationship originally with this terminal, enters into step S407 (corresponding above-mentioned step S304);
Step S407, the terminal operate as normal;
Step S408, the terminal is locked.
The operation of unbind promptly reverts to the data in the memory module ESN value at this terminal; Subscriber Identity Module binding relationship when terminal and original the binding is removed; The terminal will be inserted in the capable bindings that sticks in the terminal behind normal the startup next time, and set up new binding relationship.
