Abstract:
The described method provides for an efficient method for user equipment (104) to identify when it is in proximity to an assigned femtocell (108) in order to be handed over to a femtocell from a macro cell. As the user the equipment moves within a macro cell (106) that is defined by a serving base station (102), it is determined (202) that it is in the range of or in proximity to the femtocell to which it is registered or subscribed. Upon notification that it is near the femtocell, the user equipment sends (204) a message to the serving base station of the macro cell indicating the user equipment has identified its femtocell. The serving base station then sends (208) a message to femtocell to turn on the femtocell so that a handover of the user equipment from the macro cell and serving base station and the femtocell can be initiated. The serving base station sends (212) a response to the user equipment indicating that the femtocell is ready to receive the user equipment as a part of handover procedure.
