Method, device and system for pseudo base station identification and pseudo base station information sharing

Abstract

The invention discloses a method, device and system for identification of pseudo base stations and information sharing of pseudo base stations, so as to improve the success rate of identification of pseudo base stations and prevent other terminals from accessing pseudo base stations. The method is as follows: the terminal receives the short message sent by the base station corresponding to the cell where the terminal currently resides; judges whether the short message is a spam short message; in the case of judging that the short message is a spam short message, the terminal initiates a location area update to the base station; if the terminal judges that the location area update fails , the terminal determines that the base station is a pseudo base station, and initiates cell reselection.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for identification of pseudo base stations and information sharing of pseudo base stations. Background technique [0002] At present, the phenomenon of harassing and defrauding telecom users by sending spam messages through fake base stations is relatively rampant, which has caused adverse consequences to users' property and information security. In order to curb this phenomenon, in the prior art, two schemes for identifying pseudo base stations are proposed: [0003] Scheme 1: The terminal collects the characteristics of the pseudo base station. When the terminal selects a cell residing in the Global System for Mobile Communications (GSM) network, the terminal checks whether the characteristics of the cell conform to the collected characteristics of the pseudo base station. , then do not stay in this cell, and continue to search for ot...

Problems solved by technology

However, the terminal in the above solution only judges that the base station currently camped on is a fake base station simply by receiving spam information, which may cause misjudgment

In addition, it is assumed that the terminal judges correctly, but the terminal has camped on the pseudo base station, so the situation of accessing the pseudo base station cannot be effectively avoided.
