A positioning method and device for a pseudo-base station

Abstract

The invention provides a positioning method and device for a pseudo base station, and relates to the technical field of communication security. The positioning method of the pseudo base station includes: periodically obtaining the signaling bill data of multiple cells; according to the signaling bill data of multiple cells in the same statistical period, obtaining the cell with abnormal location update; According to the similar processing, multiple cell clusters are obtained; according to the positions of multiple cells in each cell cluster and the abnormal situation of position update, the position of the pseudo base station of each cell cluster is determined. This method analyzes the signaling bill data of multiple cells to obtain cells with abnormal location updates, clusters and clusters the cells affected by the same pseudo base station, and quickly locates the pseudo base station; on the one hand, from the perspective of time Realize the rapid positioning of the pseudo base station, on the other hand, improve the positioning accuracy and accuracy from the space, narrow the search scope of the capture work, improve the capture efficiency of the pseudo base station, and save a lot of manpower and financial resources.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to a positioning method and device for a pseudo base station. Background technique [0002] The existing technical solution monitors the signaling through the network side, and discovers the activity of the pseudo base station through the abnormal location update. However, the existing technology can only alarm the activities of the pseudo base station at the cell level. In this cell, usually manual judgment can only assume that a pseudo base station only affects one cell, and it is difficult to carry out correlation analysis. In fact, in order to improve the access rate of users, the pseudo base station usually stays at the junction of the operator's cell, which will affect the network at the same time. For multiple cells, according to the existing technical scheme, it will be considered that there are multiple pseudo base stations in the affected adjacent cells, whi...

[0002] The existing technical solution monitors the signaling through the network side, and discovers the activity of the pseudo base station through the abnormal location update. However, the existing technology can only alarm the activities of the pseudo base station at the cell level. In this cell, usually manual judgment can only assume that a pseudo base station only affects one cell, and it is difficult to carry out correlation analysis. In fact, in order to improve the access rate of users, the pseudo base station usually stays at the junction of the operator's cell, which will affect the network at the same time. If there are multiple cells, according to the existing technical scheme, it will be considered that there are multiple pseudo base stations in the affected adjacent cells, which increases the uncertainty of the location of the pseudo base stations, expands the scope of arrest, and wastes a lot of manpower and financial resources.
