Method for preventing from accessing pseudo base station and terminal provided with system for preventing from accessing pseudo base station

Abstract

The invention discloses a method for preventing from accessing a pseudo base station, which is applied to a terminal. The method comprises the following steps of receiving system information of a cell, which is transmitted on a broadcast control channel; obtaining a specific information content including a cell reselect offset, a location area identification of an absolute radio frequency channel number of an adjacent area, a general packet radio service indicator flag and an SI2quater indicator flag; and if at least two of the cell reselect offset, the location area identification of the absolute radio frequency channel number of the adjacent area, the general packet radio service indicator flag and the SI2quater indicator flag meets preconditions, judging a base station to which the cell belongs as the pseudo base station. The preconditions are as follows: a value of the cell reselection offset is a first preset value; the location area identification of the absolute radio frequency channel number of the adjacent area is inconsistent to a location area identification of the cell; the general packet radio service indicator flag indicates that the general packet radio service is not supported; and the SI2quater indicator flag indicates that the system information type 2 cannot be broadcasted.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a method for preventing access to a false base station and a terminal with a system for preventing access to a false base station. 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 vo...
