1. A method for identifying a pseudo base station for a mobile terminal, comprising:
obtaining a tracking area code (TAC) value of a detected base station;
obtaining a reference TAC value of a legal base station; and
determining the detected base station to be a pseudo base station in response to a difference value between the TAC value of the detected base station and the reference TAC value satisfying a target condition,
wherein obtaining the reference TAC value of the legal base station, comprises:
determining a current cell connection stage of the mobile terminal, wherein the cell connection stage comprises a cell searching stage or a cell reselection stage; and
obtaining the reference TAC value based on the current cell connection stage;
wherein obtaining the reference TAC value based on the determined cell connection stage, comprises:
taking a TAC value of a base station, which is the closest to a current location of the mobile terminal and is among legal base stations that the mobile terminal successfully registered within a preset time period, as the reference TAC value in response to the mobile terminal being detected to be in the cell searching stage.
