Abstract: A wireless communication system for performing a handover to a femto base station is provided. The system includes user equipment, a femto subscriber information storage, a core network entity or a macro base station or a serving base station. The femto subscriber information storage stores a list of femto base stations that allows the access of user equipment, i.e., an accessible list. The core network entity or the macro base station receives and stores the accessible list. When any of the user equipment requests a handover toward a femto base station as a target base station, and the target base station is included in the accessible list stored, the core network entity or the macro base station requests a handover toward the target base station. A method for performing a handover to the core network entity and the macro base station is also provided.
