Processing method of base station

The invention provides a processing method of a base station, which comprises the following steps: special PLMN information for UE switching is carried in a broadcast message, the UE can report a PLMN of the UE broadcasted by an adjacent cell base station and a special PLMN of a target cell for switching to the base station through CGI measurement and a measurement report, and the switched special PLMN is used for subsequent switching processing, so that the switching success rate is improved; when a source station sends a switching request, PLMN information of UE of the source station and PLMN information used for switching are transmitted to an opposite-end base station through an interface to be used for switching of the opposite-end base station, and the transmission method can be Ng/S1/Xn/X2. According to the invention, the PLMN information used for switching is carried through the base station broadcast, the UE report, and the NG/Xn or S1/X2 switching request, so that the neighbor cell is automatically
