Patent ID: 8364161

Claim:
A wireless communication system comprising: a femtocell base transceiver station controller which is assigned with a plurality of wireless zones; a plurality of femtocell base transceiver stations which communicate with the femtocell base transceiver station controller and which are operable to form a femtocell as a wireless zone; and a radio network controller (RNC) which assigns the plurality of wireless zones to the femtocell base transceiver station controller, wherein the femtocell base transceiver station controller is operable to perform a wireless zone setting on the plurality of femtocell base transceiver stations instead of the RNC and to request the plurality of femtocell base transceiver stations to measure signal quality information between the femtocell base transceiver stations, each of the plurality of femtocell base transceiver stations is operable to, upon receipt of the request of measuring the signal quality information, measure a quality of a signal received from another femtocell base transceiver station and transmit the measurement result to the femtocell base transceiver station controller, and the femtocell base transceiver station controller is operable to adaptively change the wireless zone setting according to the measurement result received from the femtocell base transceiver station.
