Abstract

The invention relates to a method for realizing a mobile terminal to lock the network or a card by utilizing a driver. The method for realizing a mobile terminal to lock the network, which comprises the following steps: binding the driver used by the mobile terminal and the terminal, and utilizing the terminal and the driver to dually bind the Mobile County Code (MCC) and Mobile Network Code (MNC) of the user SIM card. The method for realizing a mobile terminal to lock a card by utilizing a driver, which comprises the following steps: binding the driver used by the mobile terminal and the terminal, and utilizing the terminal and the driver to dually bind the Internal Mobile Subscriber Identification Code (IMSI) of the user SIM card. The method first adopts the driver to bind the terminal, and then adopts the terminal and the driver to dually bind the SIM card, thereby greatly improving security and preventing illegal unlocking to a great extent.

Description

technical field

[0001] The present invention relates to the technical field of communication, and more specifically, relates to a method for realizing network locking or card locking of a mobile terminal by using a driver. Background technique

[0002] With the global popularity of 3G networks and the intensification of competition among operators, the sales methods of wireless terminal devices (Wireless Terminal Device) are mostly customized by operators in addition to the sales channels of traditional manufacturers, and large-scale subsidies are low. At this time, it is particularly important for the wireless terminal equipment to bind and restrict the use of the operation network of a specific operator. However, the current network lock scheme is only implemented on the terminal, so there are disadvantages such as low protection and easy cracking.

[0003] For example, the Chinese patent application No. CN200710087431 titled "Asymmetric Algorithm-Based Protection and Unl...

Embodiment Construction

[0023] This patent proposes a method of using the driver to realize network lock and card lock. Firstly, the binding relationship between the driver and the terminal is realized, that is, the driver only guarantees smooth communication with one terminal port, and the terminal can be used normally with the support of this driver, and other terminals Under this drive, hackers are prevented from cracking the terminal action because the port is unreachable; then use the terminal and the driver to double bind the country code (Mobile Country Code, hereinafter referred to as MCC) and mobile network code (Mobile Network Code, hereinafter referred to as MNC) of the user's SIM card , that is, only this type of SIM card can guarantee the normal use of the driver, thereby realizing the network lock. If the driver is bound with the International Mobile Subscriber Identification number (IMSI) of the SIM card, the card can be locked. Since the method first uses the driver to bind the termina...
