Pseudo base station identification and pseudo base station information sharing method, device and system

The invention discloses a pseudo base station identification and pseudo base station information sharing method, device and system so as to improve pseudo base station identification success rates and prevent other terminals from accessing a pseudo base station. The method comprises the following steps: a terminal receives a short message sent by a base station corresponding to a cell where the terminal resides at present, whether the short message is a garbage message is determined, a location area renewal for the base station is initiated by the terminal, that the base station is a pseudo base station is determined by the terminal if that the location area renewal fails is determined by the terminal, and cell reselection is initiated. 本发明公开了伪基站识别和伪基站信息共享的方法、设备及系统，以提高伪基站识别成功率，避免其他终端接入伪基站。该方法为：终端接收终端当前驻留小区对应的基站发送的短信；判断短信是否为垃圾短信；在判断短信为垃圾短信的情况下，终端向基站发起位置区更新；若终端判断位置区更新失败，则终端确定基站为伪基站，并发起小区重选。
