Pseudo base station identification method and system

Abstract

The invention provides a pseudo base station identification method and system. The method comprises the following steps: processing real-time data of an MC signaling interface through a pretreatment mode and obtaining a message file where a source LAC is not in a local LAC list in the data, wherein the message file comprises a plurality of abnormal position messages, each abnormal position messagecomprising a source LAC and target cell identification; according to a pseudo-base station identification model, analyzing the source LACs and corresponding target cell identification in the messagefile and obtaining a cell list influenced by a pseudo base station; analyzing sequential order of the abnormal position messages of each target cell in the cell list through time granularity information, and obtaining activity trajectory of the pseudo base station according to time sequence; and according to the activity trajectory of the pseudo base station, screening out a pseudo-base station suspect carrier in disturbed users under the pseudo base station. The method can identify the pseudo-base station suspect carrier accurately in time.

Description

technical field [0001] The invention relates to a communication technology, in particular to a pseudo base station identification method and system. Background technique [0002] "Pseudo base station" is a miniaturized, vehicle-mountable, and easy-to-move wireless communication device. It illegally uses the frequency of the operator, uses high power to transmit strong signals and optimizes wireless parameter settings, tricks customers into accessing mobile phones, and collects customer information. At the same time, any sending number can be forged to forcibly send bad information to mobile phones in the coverage area. Pseudo base stations not only interfere with normal communication of users, cause a large number of customer complaints, seriously affect the image of operators, but also infringe on users' legal property rights, seriously disrupt market order, and affect social stability. [0003] In order to be able to identify and locate pseudo-base stations in real time a...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the suspected pseudo base station cell is determined based on the fluctuation of location signaling, there are also cases where the increase in the flow of people causes the fluctuation to exceed the threshold, and it is also judged as a suspected pseudo base station cell, so the determination accuracy is not high

[0006] 2. The minimum granularity is relatively large, which is at the community level. The on-site positioning personnel need to screen a large location area, and the positioning takes a long time

[0007] 3. The data delay is large, and the timeliness of the mobile pseudo-base station cannot meet the requirements
