Abstract

The invention provides a determination method of a pseudo base station and a mobile terminal. The method comprises the steps of sending a base station parameter acquiring request to a base station of the local community through the mobile terminal; receiving the base station parameters from the base station through the mobile terminal; comparing the base station parameters with the preset base station parameters of an operator; if the base station parameters are the same as the base station parameters of the operator, acquiring electric signal strength of the base station; comparing the variable of the electric signal strength of the base station within the preset time quantum with the preset strength variation value; if the variable of the electric signal strength of the base station within the preset time quantum is less than the preset strength variation value, comparing the electric signal strength of the base station with the preset electric signal strength; if the electric signal strength of the base station is more than the preset electric signal strength, determining that the base station is the pseudo base station. With the adoption of the determination method of the pseudo base station and the mobile terminal, the pseudo base station can be quickly and conveniently recognized, and meanwhile, the signaling load of the base station can be reduced; the privacy can be prevented from disclosing; in addition, the pseudo base station can be timely positioned.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for judging a pseudo base station and a mobile terminal. Background technique [0002] In a cellular mobile communication system, when a mobile terminal selects a new public land mobile network (PLMN for short), it will reside in a cell with reliable downlink decoding and good uplink communication quality, so that the mobile terminal Receive PLMN paging information and system information and can establish a call process with a good cell and other behaviors. At the same time, it monitors the broadcast control channel (BCCH) carrier that can reselect the frequency point of the adjacent cell. The pseudo base station sets the BCCH carrier as the BCCH carrier of a certain adjacent cell to increase the strength of the transmitted signal so that the mobile terminal in the target area can receive Signal to the pseudo base station to reselect to the pseudo base sta...
