Problems solved by technology
[0003] Since the pseudo base station equipment is often hidden in vehicles or backpacks by criminals, it moves with the movement of vehicles and people in a short period of time, and will not stay in a certain place for a long time. Therefore, in practical applications, it often requires a lot of manpower to track The movement of the pseudo base station, and the accuracy of trajectory tracking is low

Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0018] After the mobile station is connected to the fake base station, since the fake base station does not actually communicate with the telecom core network, the fake base station event will cause the surrounding base station cell signaling to behave abnormally. The abnormality in the handover event signaling is mainly reflected in: during the period from the opening of the pseudo base station to the closing of the pseudo base station, the frequency of cut-in of the surrounding base station cells decreases, while the frequency of hand-out increases, but a large number of hand-outs fail; , the cut-in frequency increases, and this value is much greater than the cut-in frequency before the pseudo base station is closed.
[0019] Such as figure 1 As shown, the pres...

The invention discloses a pseudo base station motion track identification method. The method comprises the following steps: extracting all switching event signaling in a period of time from a database, calculating a switching event index of each base station in a certain time period, identifying an abnormal base station suspected to be influenced by pseudo base station equipment, storing abnormalbase station information in an abnormal base station identification record table, and constructing a pseudo base station information table at the same time; respectively calculating a position distance and a discovery time difference between each abnormal base station in the abnormal base station identification record table and each base station in the pseudo base station information table, obtaining a track number of each abnormal base station in the abnormal base station identification record table, and writing the abnormal base station information of which the track numbers are obtained into the pseudo base station information table; and obtaining the motion track of each pseudo base station according to the position, the discovery time and the track number of the base station in the pseudo base station information table. The invention belongs to the technical field of information, and can realize accurate tracking of a movement track of a pseudo base station by identifying the basestation which is influenced by pseudo base station equipment and causes abnormal signaling performance.
Description
technical field [0001] The invention relates to a method for identifying motion tracks of pseudo base stations, and belongs to the field of information technology. Background technique [0002] Pseudo base station refers to an illegal radio device that has not passed the national radio transmission equipment model approval and has not obtained a network access permit. Criminals use it to pretend to be a base station to absorb surrounding base station mobile stations, obtain IMSI, IMEI and other information, and send fraudulent messages to users , Harassing short messages. The physical reason for its existence is that GSM protocol communication adopts one-way authentication, that is, only the base station verifies the identity of the mobile phone, but the mobile phone does not verify the authenticity of the base station. If the pseudo base station sets high-power wireless signal transmission and better cell reselection parameters, this makes it easy for the mobile station to...
