A pseudo-base station identification and positioning method and device

Abstract

Embodiments of the present invention provide a method and device for identifying and locating pseudo-base stations. The method includes: receiving MR data sent by multiple user terminals; Match with the whole network neighbor cell configuration table and the serving cell-neighbor cell distribution model table, use the wireless network cell meeting the first preset condition as the missing neighbor cell, and store the MR data including the missing neighbor cell into the missing configuration In the adjacent cell table; if it is judged that the number of MR data of missing adjacent cells within the preset time period in the missing adjacent cell table is greater than the first threshold, and the RSRP of the missing adjacent cells is greater than the second threshold, the missing The multiple MR data corresponding to the adjacent area are stored in the pseudo base station table; according to the latitude and longitude of multiple MR data of the pseudo base station cell in the pseudo base station table, the location information of the pseudo base station cell is calculated. The apparatus performs the method described above. The embodiments of the present invention improve the accuracy of identification and positioning of pseudo base stations.

Description

Technical field[0001]The embodiment of the present invention relates to the field of mobile communication technology, and in particular to a method and device for identifying and positioning a pseudo base station.Background technique[0002]With the development of mobile communication technology, more and more base stations of various mobile communication systems are built, and mutual interference between base stations is likely to occur, resulting in a decrease in link quality and system capacity. A large number of various trunking communication systems have been built and operated in my country, among which the mobile communication network represented by the three major operators has become one of the lifeblood of the national economy. Among them, the pseudo base station system has the heaviest impact and the greatest harm on wireless networks. The pseudo base station system is a simulated mobile communication wireless base station system and a background analysis system. It uses th...

However, the shortcomings of searching for pseudo-base stations in the prior art are mainly manifested in the following aspects: (1) The detection method based on network signaling features of operators is based on post-mortem monitoring, and there is a serious lack of timeliness. Spam text messages; in actual work, in order to avoid attacks, fake base stations have the characteristics of strong mobility and are difficult to locate accurately; (2) The monitoring method of mobile APP based on mobile phone switching characteristics and SMS characteristics requires a large number of users to install terminal software, It affects the user experience; on the other hand, the mobile APP makes judgments based on mobile phone events and SMS characteristics, and there is a possibility of misjudgment; (3) On-site frequency analysis and detection methods require technicians to arrive at the scene to operate handheld devices for detection, which is costly and inefficient. Unable to monitor on a large scale

In addition, the existing 2G pseudo base station monitoring platform mainly relies on LAC update. The LTE network system has no LAC information, and location update is no longer the only means for 4G pseudo base stations. Therefore, this method cannot realize the identification and positioning of 4G pseudo base stations.
