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 access to a pseudo base station, and is applied to a terminal. The method comprises the steps of receiving a system message transmitted by a cell on a broadcast control channel; acquiring a specific message content including cell reselect reset, a periodic location update timer, location area identifiers of adjacent areas of the same frequency point, and a second type system message broadcast identifier according to the system message; and if at least two of the cell reselect reset, the periodic location update timer, the location area identifiers of the adjacent areas of the same frequency point, and the second type system message broadcast identifier satisfy a preset condition, then judging a base station of the cell belongs to be the pseudo base station. The preset condition comprises that the value of the cell reselect offset is a first preset value; the value of the periodic location update timer is a second preset value; the location area identifiers of the adjacent areas of the same frequency point are not consistent with a location area identifier of the cell; and the second type system message broadcast identifier shows that a second type system message is not broadcasted. The invention further proposes a terminal with a system for preventing access to the pseudo base station. The method for preventing access to the pseudo base station and the terminal with the system for preventing access to the pseudo base station provided by the invention can effectively prevent 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...
