Embodiment Construction

[0052] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0053] An illegal cell is a cell where a terminal can reside in a forged cell fabricated by criminals by simulating the frequency of a legal mobile network driven by economic interests. Criminals can use the illegal cell to absorb normal user terminals from the legal network to the fake illegal cell, and use the network where the illegal cell is located to pu...

Abstract

The present application provides a method for identifying an illegal cell and a terminal, wherein the method includes: during location updating, detecting whether an authentication request sent by the network where the cell to be identified is located is received, and when receiving the authentication request, through Feedback an authentication response with wrong authentication parameters to determine whether the cell to be identified is an illegal cell, and when the authentication request is not received, check whether the identity of the IMSI type sent by the network where the cell to be identified is located is received The identification request determines whether the cell to be identified is an illegal cell. The technical solution improves the recognition degree and accuracy of identifying illegal cells, and solves the problem that illegal cells interfere with normal communication of terminals.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to an illegal cell identification method and terminal. Background technique [0002] With the rapid development of communication technology, an illegal cell that can simulate the frequency of a legal mobile network has emerged. When a terminal resides in an illegal cell, the network where the illegal cell is located can not only push spam messages to the target terminal or steal private information such as the terminal’s International Mobile Subscriber Identification Number (IMSI), but also make the terminal disconnect from the legal network , affect the normal communication of the user, and even cause property damage to the user. [0003] At present, the closest existing technology is mainly the pseudo base station identification method disclosed in the application number 201410222855.9. In this method, when the terminal receives the authentication request ...
