Embodiment
As shown in Figure 1, Subscriber Identity Module is connected with portable terminal by card interface circuit, and the CPU of portable terminal reads the card number of Subscriber Identity Module by card interface circuit, in the portable terminal FLASH memory card number that prestores is arranged, and compares in internal memory.Portable terminal is connected with computer by diagnosis fastening means such as data wire, and the diagnostic software in the computer can be provided with the data parameters of portable terminal.
As shown in Figure 2, the card number that prestores in the mobile terminal memory is ME_ID, the Subscriber Identity Module card number that is using is ID, the user provides start-up command, portable terminal carries out opening initialization, and from the User Recognition card memory that is using, read the card number ID of Subscriber Identity Module, portable terminal carries out the step that oneself state is judged then:
Be in deactivated state, the function of expression portable terminal check card not to be used, and portable terminal continues start process;
Be in user mode, portable terminal compares the card number ME_ID that deposits in advance in the card number ID of the Subscriber Identity Module of reading that is using and the memory in internal memory, comparative result is identical to be ID=ME_ID, then portable terminal continues start process, if comparative result is inequality is ID ≠ ME_ID, and then portable terminal is a disarmed state;
Be in state of activation, portable terminal stores the card number ID of the Subscriber Identity Module of reading in the mobile terminal memory into, replace the card number ME_ID that stores in advance in the memory, and status of mobile terminal is set to user mode, continue start process again, this state is to change a new Subscriber Identity Module for portable terminal, and check card number during start each time afterwards.
Have a flag bit to represent three kinds of states of this function in portable terminal, generally speaking, portable terminal is in user mode, has only the permission through Virtual network operator, the user can change portable terminal by user mode to state of activation or deactivated state.
