Description

A method for realizing terminal card lock

technical field

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

Dual-card dual-standby service means that a communication terminal can simultaneously insert two Subscriber Identity Module (Subscriber Identity Module, hereinafter referred to as: SIM) cards with different card numbers, 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, just like the GSM (Global System for Mobile Communications, GSM for short) standard.

At present, in the dual-card dual-standby service opened by the terminal, the legitimacy of the two SIM cards is not verified, so that users of one operator can use another operator's network to achieve their communication purposes, thus damaging the another operator's benefit.

Contents of the invention

The purpose of the present invention is to solve the problem of verifying the legitimacy of the dual card in the dual card dual standby service, and provide a method for realizing the dual card dual standby terminal card lock, and verify the legitimacy of the SIM card used by the terminal , to ensure that the dual cards can only use the network of the same operator.

In order to achieve the above object, the present invention provides a method for realizing terminal card lock, the method includes the following steps:

Acquiring the state information of the two SIM cards in the terminal; according to the state information, judging whether the two SIM cards in the terminal belong to the same operator or registered to the same network, if so, then end; otherwise, the two SIM cards in the terminal A SIM card is locked.

The state information may be the International Mobile Subscriber Identity (IMSI) of the two SIM cards, and the method is specifically: obtaining the two SIM cards from the two SIM cards in the terminal. The IMSI number of the SIM card;

The state information may also be roaming identities of the two SIM cards, and the method specifically includes: obtaining the roaming identities of the two SIM cards in the terminal from the home location register;

The state information may also be the network identifiers registered to the network by the two SIM cards, and the method specifically includes: acquiring the network identifiers of the two SIM cards in the terminal from the network;

When judging whether the two SIM cards belong to the same operator or are registered to the same network, it also includes: displaying the prompt information for selecting the registration method for the SIM card to be registered to the corresponding network, and according to the command input by the user Execute the operation of registering the SIM card on the network.

The locking of the two SIM cards specifically includes: displaying information that normal operations cannot be performed, and the terminal starts a card locking program for the two SIM cards.

It can be seen from the above technical solutions that the present invention comprehensively judges whether the user's SIM card is legal by combining the IMSI number of the SIM card, the network identifier of the registered network, and the roaming identifier. If it is legal, the terminal allows the SIM card to be used normally; if it is not legal, the terminal does not allow the SIM card to be used, and the card is locked. Therefore, the present invention realizes the verification of the legality of the dual cards in the dual card dual standby service, and can ensure that the dual cards can only use the network of the same operator.
