Pseudo base station identifying method and device

Abstract

Embodiments of the present invention disclose a pseudo base station identifying method and device that are used for identifying the pseudo base station effectively. The method includes the steps that when a terminal is accessed to a base station of a GSM network, the terminal sends trigger information for initiating an authentication flow of the terminal for a network side device to the network side device corresponding to the base station; the terminal receives authentication-related information sent by the network side device based on the trigger information, wherein the authentication-related information includes first authentication information provided by the network side device; and the terminal compares the first authentication information with second authentication information of the terminal so as to obtain a comparison result, when the comparison result indicates that the first authentication information and the second authentication information are different, the base station is determined as a pseudo base station.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for identifying a pseudo base station. Background technique [0002] A pseudo base station is a fake base station, disguised as an operator's base station, and searches for the Subscriber Identity Module (SIM) of a mobile phone centered on itself and within a certain radius through related equipment such as short message mass transmitters and short message transmitters. ) information, and fraudulently use other people's mobile phone numbers to forcibly send short messages such as fraud and advertising to the user's mobile phone. The user (Subscriber) mobile phone may also be various types of communication terminal equipment or user equipment, including but not limited to the aforementioned mobile phone. [0003] Pseudo base station equipment generally consists of transceivers and laptops, see figure 1 As shown, a schematic diagram of a ...

AI Technical Summary

Problems solved by technology

[0014] Existing equipment dedicated to identifying base stations can identify fake base stations based on the above characteristics, but it cannot guarantee 100% accuracy, and personnel need to go to the site to confirm

Ordinary terminals cannot identify fake base stations according to characteristics (1) and (3), because the terminal cannot obtain the number of frequency points of the base station. In addition, the location update process is also a normal protocol process for the terminal.

Therefore, the terminal can only be identified according to the characteristic (2), and the identification accuracy rate cannot reach 100%. In addition, the pseudo base station can easily cause the terminal to fail to identify the pseudo base station by simply modifying the C2L parameters.
