Embodiment 1

[0019] As shown in Figure 1, this embodiment is to use the method of first judging whether the two SIM cards belong to the same operator, and then combining the roaming status of the two SIM cards to judge whether the two SIM cards are in the same network. The legality of the SIM card is judged. Its process comprises the following steps: start the standby terminal of two SIM cards in the terminal;

[0020] Step 101, obtaining the IMSI numbers of the two SIM cards from the two SIM cards;

[0021] Step 102, comparing the IMSI numbers of the two SIM cards;

[0022] Step 103, judging whether the two SIM cards belong to the same operator, if the two SIM cards belong to the same operator, then end; if the two SIM cards do not belong to the same operator, then perform step 104;

[0023] Step 104, the two SIM cards both initiate a registration request to the corresponding network;

[0024] Step 105, the two SIM cards are registered to the corresponding network;

[0025] Step 106,...

Embodiment 2

[0044] As shown in Figure 2, this embodiment uses the roaming status of the two SIM cards to determine whether the two SIM cards are in the same network, and then determines whether the two SIM cards belong to the same operator network. The legitimacy of a SIM card is judged. Its process includes the following steps: start the standby terminal of the two SIM cards in the terminal; the two SIM cards all initiate a registration request to the corresponding network, and the two SIM cards are registered to the corresponding network;

[0045] Step 201, obtaining the roaming identities of the two SIM cards from the home location register;

[0046] Step 202, comparing the roaming identifiers of the two SIM cards;

[0047] Step 203, judging whether the two SIM cards are in the non-roaming state, if the two SIM cards are in the non-roaming state, then perform step 204; if the two SIM cards are not in the non-roaming state, then perform the step 210;

[0048] Step 204, obtaining the ...

Embodiment 3

[0070] As shown in Fig. 3, this embodiment adopts the method of first judging whether the two SIM cards belong to the same operator, and then combining the roaming status of the two SIM cards to judge whether the two SIM cards are in the same network. The legality of the SIM card is judged. Its process comprises the following steps: start the standby terminal of two SIM cards in the terminal;

[0071] Step 301, obtaining the IMSI numbers of the two SIM cards from the two SIM cards;

[0072] Step 302, comparing the IMSI numbers of the two SIM cards;

[0073] Step 303, judging whether the two SIM cards belong to the same operator, if the two SIM cards belong to the same operator, then end; if the two SIM cards do not belong to the same operator, then perform the step 304;

[0074] Step 304, the two SIM cards both initiate a registration request to the corresponding network, the two SIM cards are registered to the corresponding network, and the network identification of the ne...

Abstract

The related locking method for dual-card dual-standby terminal comprises: obtaining state message of two SIM card in terminal to decide whether two SIM cards belong to one provider or have registered same network, yes to finis; or else, locking two cards. This invention combines the IMSI number, registered network mark, and the cruise mark together to decide whether SIM card legal, and ensures the dual-card dual-standby terminal only using same provider network.

Description

technical field [0001] The invention relates to a method for realizing terminal card locking in a dual-card dual-standby service, and belongs to the technical field of mobile communication. Background technique [0002] The dual-card dual-standby service means that a communication terminal can insert two subscriber identity module (Subscriber Identity Module, hereinafter referred to as: SIM) cards with different card numbers at the same time, and make them in the power-on state at the same time, that is, support two card numbers to be online at the same time. Users can choose the corresponding service package for each SIM card according to their needs, and can make, receive and send and receive text messages arbitrarily. In addition, users can also preset the order of receiving and making calls to meet their individual needs. Generally, the dual cards in the dual card dual standby service belong to the same mobile communication standard, such as the GSM (Global System for M...
