The present invention provides a method and device for time-sharing restoration of IMEI. The method includes: performing time-sharing rotation on multiple cells covered by the 2G base station through a 2G base station; detecting the International Mobile Subscriber Identity code of a terminal through a 3G or 4G base station The IMSI, the received power corresponding to the IMSI, and the operator of the IMSI; in each time-sharing cycle, according to the detected operator of the IMSI of the terminal, the operator of the 2G base station, and the detected operator of the IMSI The IMSI of the terminal and the received power corresponding to the detected IMSI of the terminal are determined to determine whether to restore the International Mobile Equipment Identity (IMEI) for the terminal. The present invention obtains information such as the IMSI, receiving power, and home operator of the terminal through the 3G or 4G base station, and then restores the IMEI information of the terminal through the 2G base station, which can reduce the number of 2G base stations used, the volume occupied by the base station and the power of the base station. consumption.
Description
technical field [0001] The present invention relates to the technical field of communications, and in particular, to a method and device for restoring IMEI time-sharing sharing. Background technique [0002] Manufacturers of mobile terminals allocate an International Mobile Equipment Identity (IMEI) to each mobile terminal before each user terminal leaves the factory. The IMEI is an identifier used to distinguish mobile terminals and is stored in the mobile terminal. Since the IMEI code is published, many illegal manufacturers directly steal the IMEI of legitimate terminals, and multiple cell codes covered by 3G or 4G base stations, resulting in different terminals having the same IMEI code. The tested terminals have flowed into the market, bringing many security risks and causing disorderly competition in the market. Therefore, in order to maintain a normal market environment, it is necessary to perform restoration supervision on the IMEI code of the terminal. In addition...
