The disclosure is related to handover for user equipment between femtocell base stations having different closed subscriber group (CSG) identifiers. A method may be provided for allowing handover of user equipment between base stations belonging to different organizations. The method may include collecting, by a first base station, information corresponding to identifiers of neighbor base stations, selecting handover-allowable base stations from the neighbor base stations having an organization identifier different from that of the first base station, and enabling handover for the user equipment from the first base station to a second base station based on the selected handover-allowable base stations for a handover request of the user equipment from the first base station to the second base station.
