Pseudo base station protection method and device

Abstract

A pseudo base station protection method is applied to a terminal. The method comprises the steps that if before authentication succeeds after 3C / 4C community registration request information or region update request information or region update request information is sent to the network side, redirection messages sent by the network side are received, and whether the redirection messages contain information redirected to a 2G network or not is determined; if the redirection messages contain the information redirected to the 2G network, no response is caused to the redirection messages; if the redirection messages do not contain the information redirected to the 2G network, redirection is conducted according to the redirection messages. The invention further provides a pseudo base station protection device. The safety of the terminal user network can be guaranteed.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a method and device for protecting a pseudo base station. Background technique

[0002] False base stations are base stations of public mobile operators forged by criminals. False base stations attract surrounding mobile phone users by forging 2G networks and increasing their own transmission power. When the mobile phone user successfully resides in the fake base station, the fake base station can obtain the identity information of the mobile phone user, and then transmit illegal information, and then obtain illegal profits from it. At present, a composite pseudo-base station has appeared. The composite pseudo-base station integrates 3G / 4G base stations and 2G base stations, and attracts surrounding mobile phone users by increasing the transmission power of 3G / 4G base stations. Perform redirection to 2G networks and subsequently perform illegal activities at 2G base stati...
