Method for realizing mobile terminal to lock network or card by utilizing driver

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...

Problems solved by technology

However, this method has the following deficiencies: 1. It is necessary to perform a locking operation before selling, and the unlocking code and key are stored in the mobile terminal, and the key or unlocking code is in a one-to-one relationship with the terminal, so the mobile terminal must be locked one by one. Locking increases the production burden to a certain extent, locking the network is cumbersome and wastes a lot of time; 2. The locked public key and private key are kept separately, and the operation is completed through the interaction between the DIAG port and the locking software, so it is safe 3. Since the terminal is in the locked network state, but the mode is not in the working mode, and the locked network is controlled in the NV, it is easy to be cracked

This solution realizes the one-to-one correspondence between the SIM card and the terminal by writing the IMEI number of the device in the SIM card, but this solution has the following shortcomings: 1. The card locking mechanism is too simple and easy to crack, just write another one with the same IMEI number The terminal can realize the reuse of the SIM card, so there is no way to guarantee the interests of the operator; 2. After the user changes the card, the lock operation must be performed to realize the machine-card interlocking function

[0006] For example, the Chinese patent application CN200710130098.2 titled "A Wireless Terminal and Its Method for Interlocking and Unlocking It with a Subscriber Identification Card" is another solution to realize machine-card interlocking. This patent writes in the SIM card The random number thus realizes the one-to-one correspondence between the SIM card and the SIM card, but interlocking cannot be realized when the user changes the SIM card, and when the user takes the SIM card to other terminals, it cannot be used normally

[0007] The above-mentioned network locking methods only realize the network locking function on the terminal, and it is possible to crack through the exhaustive method, so to a certain extent, they are easy to crack and have poor protection.
