Embodiment
Basic thought of the present invention is: on the path between portable terminal master chip and two SIM card the two-way encryption chip is set; After the two-way encryption chip is received the notice of master chip, read the information parameter of any one or two SIM card, and the information parameter of the SIM card that reads and the information parameter of the SIM card that self has stored compared, the information parameter of determining the SIM card that reads and the information parameter of the SIM card of having stored make the SIM card corresponding with the information parameter of the SIM card that reads invalid not simultaneously.
Wherein, the described method that the two-way encryption chip is set is: by the SIM card interface, two-way encryption chip of serial or parallel connection on the path between portable terminal master chip and two SIM card, described SIM card interface comprises: SIM card I/O (SIMIO) interface and SIM card clock (SIMCLK) interface; Two SIM card all link to each other with master chip through this two-way encryption chip; The information parameter of described SIM card includes but not limited to MCC and MNC, and for example: the information parameter of SIM card also can be international mobile subscriber identity (IMSI) etc.
Among the present invention, before portable terminal dispatches from the factory, in the two-way encryption chip, stored a group or more the information parameter of SIM card of operator's appointment in advance.
Information parameter with SIM card is that MCC and MNC are that example is described in further detail the present invention below.
Fig. 1 carries out method of encrypting realization flow schematic diagram for the present invention to double-card mobile terminal, and as shown in Figure 1, the performing step of this flow process is as follows:
