Pseudo base station identification method and device, and terminal

Abstract

The invention discloses a pseudo base station identification method and a pseudo base station identification device, and a terminal. The method comprises the steps of S1, acquiring a plurality of feature parameters of system information of a base station to be accessed, and feature values of the plurality of feature parameters; S2, comparing the feature values with a preset value, and determining decision values of the plurality of feature parameters; and S3, judging whether the sum of the decision values of the plurality of feature parameters is more than a preset decision threshold, and if yes, determining that the base station is a pseudo base station. According to the method, the security of a mobile terminal in use under the condition of accessing a GSM network for communication is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a pseudo base station identification method, device and terminal. Background technique [0002] "Pseudo base station" is a false base station, which is a high-tech instrument. It uses SMS group senders and other related equipment to search for mobile phone card information centered on it and within a certain radius, and forcibly connects the user's mobile phone signal to the pseudo base station. , preventing users from connecting to public telecommunications networks. The fake base station pretends to be the base station of the operator, arbitrarily uses other people's mobile phone number to forcibly send short messages such as fraud and advertising to the user's mobile phone, harassing the user and affecting the normal mobile phone use of the mobile phone user. Moreover, the pseudo-base station does not have the voice communication resources of the normal base ...

AI Technical Summary

Problems solved by technology

[0003] (1) Deceiving the user terminal to stay in the fake base station, causing the terminal to be separated from the normal GSM service network, causing the user to be unable to perform calling and calling, and seriously affecting the normal use of user communication services

(2) The user terminal frequently interacts with signaling, which makes the wireless resources in the coverage area of ​​the pseudo base station tense, seriously affecting the normal communication of the user

(3) Defrauding user identification information, and then using it to eavesdrop on users and track their location, posing a threat to user privacy

The fake base stations discovered so far are mainly for sending commercial advertisements, but if the fake base stations are used by criminals to send reactionary text messages, it will cause more serious social harm

[0004] However, there is currently no better method for identifying pseudo base stations
