Method for preventing access to pseudo base station, and terminal with system for preventing access to pseudo base station

Abstract

The invention discloses a method for preventing the access to a pseudo base station, and the method is used for a terminal. The method comprises the steps: receiving a system message transmitted by a cell on a broadcast control channel; obtaining a specific message content which comprises the cell reselection bias, a periodic position updating timer, a universal grouping wireless service identification and a position region identification of the same frequency point neighbor cells according to the system message; and determining that the cell is the pseudo base station if two of the cell reselection bias, the periodic position updating timer, the universal grouping wireless service identification and the position region identification of the same frequency point neighbor cells meet preset conditions. The preset conditions comprise the conditions that the value of the cell reselection bias is a first preset value; the value of the periodic position updating timer is a second preset value; the universal grouping wireless service identification indicates that the universal grouping wireless service is not supported; and the position region identification of the same frequency point neighbor cells is not consistent with the position region identification of the cell. The invention also proposes the terminal with a system for preventing the access to the pseudo base station. The method and terminal can effectively prevent the access to the pseudo base station.

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...
