Problems solved by technology
However, with the development of pseudo-base station identification technology, operators of pseudo-base stations have also begun to use some technical means to evade capture, such as placing pseudo-base station equipment on vehicles, moving continuously after the equipment is turned on, and constantly changing the LAC during the movement process. , these methods will make it difficult for the pseudo base station identification system to analyze which location updates come from the same pseudo base station
[0004] To sum up, since most of the current pseudo-base stations are vehicle-mounted systems, which move fast and change LAC during the movement, it is impossible to effectively identify which abnormal location updates come from the same pseudo-base station, and thus it is impossible to analyze the influence of the pseudo-base station scope

Embodiment Construction
[0026] In view of the fact that most of the current pseudo-base stations are vehicle-mounted systems, the movement speed is relatively fast, and the LAC is changed during the movement process, which makes it impossible to effectively identify which abnormal location updates come from the same pseudo-base station, and thus cannot analyze the influence range of the pseudo-base station. The embodiment of the invention proposes a technical solution, by updating the data obtained at the location of the terminal, the abnormal location update data of each cell is determined, and then further according to a given algorithm, the motion track of the pseudo base station is obtained, so that the pseudo base station can be effectively identified. The base station can accurately analyze the influence range of the fake base station.

The invention discloses a method and a device for identifying a pseudo base station. The method comprises the following steps of obtaining location updating data of a terminal; determining abnormal location updating data of each cell, which is formed by the pseudo base station, from the obtained location updating data; generating a pseudo location area code LAC link of the cell for the abnormal location updating data of each cell; combining pseudo LAC links between the cells until convergence and generating a pseudo LAC group; and determining a movement locus of the pseudo base station according to the generated pseudo LAC group. According to the method and the device, dynamic real-time positioning is carried out on the location of the pseudo base station to facilitate on-site arrest and effectively identify which abnormal location updating is from the same pseudo base station, so that the range of influence of the pseudo base station is analyzed.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for identifying a pseudo base station. Background technique [0002] Pseudo base station is a new type of mobile communication equipment developed based on software radio technology. It is used to simulate the base station of telecom operators. (English: MobileStation, abbreviation: MS) and the Um interface between the base station subsystem (English: BaseStationSubsystem, abbreviation: BSS), pretending to be a legal BSS and network subsystem (English: NetworkSubSystem, abbreviation: NSS), intruding into mobile The communication link of the communication network disconnects the MS from other parts of the legal network, and diverts the MS to communicate with the fake base station, so as to achieve the purpose of obtaining terminal information and transmitting illegal content to the terminal terminal. [0003] At present, the identification metho...
