A positioning method and device for a pseudo-base station

Abstract

The invention provides a positioning method and device for a pseudo base station, relates to the field of communication technology, and is invented for improving the accuracy of positioning a pseudo base station. The method includes: obtaining location update information of the user terminal, the location update information including the updated location area code of the user terminal location and the type of location update; judging whether the location update information satisfies a specific condition; if so, The pseudo base station is then positioned according to the location update information. Wherein, the specific condition is: in the two adjacent location updates of the user terminal, the first location area code after the previous location update is the same as the second location area code after the next location update, and the previous location The type of update is normal location update and the previous location update is successful, and the type of the next location update is normal location update. The invention can be used in the pseudo base station acquisition technology.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a positioning method and device for a pseudo base station. Background technique [0002] At present, a large number of pseudo base stations have appeared in the society. The pseudo base station simulates the operator's network to send signals to the user, so that the user terminal resides in the pseudo base station, and the pseudo base station obtains the user terminal number and sends advertisements, fraudulent SMS, etc. to the user, affecting the normal communication of the user terminal. At the same time, the pseudo base station will seriously interfere with the operator's network and cause frequency interference to the operator's network. Therefore, it is very important to capture the pseudo base station through positioning. [0003] There are currently two main methods to locate pseudo base stations: [0004] The first method is the former LAC (location area...

AI Technical Summary

Problems solved by technology

[0005] In the process of realizing the above positioning and capturing of pseudo-base stations, the inventors found that there are at least the following problems in the prior art: For the pre-LAC method, since many users in the current network fail to update their locations, the value of the pre-LAC reported after the location update fails is 65534. This method counts many users who have not logged in to the pseudo base station network, so the accuracy is low

Therefore, the analysis and positioning of pseudo base stations based on the change analysis method of location update times also has the problem of low accuracy.
