SYSTEMS AND METHODS FOR CELL SEARCH IN MULTI-TIER COMMUNICATION SYSTEMS

摘要

A mobile station capable of accessing a wireless network comprising a plurality of macro-base stations and a plurality of femto-base stations. The mobile station comprises: 1) a transceiver that communicates with the macro-base stations and femto-base stations; 2) a message processor coupled to the transceiver; and 3) a memory coupled to the message processor that stores a white list of CSGID values associated with at least one closed subscription group to which the mobile station subscribes. The message processor transmits to a first macro-base station a first control message that contains at least one CSGID value from the white list. The message processor receives from the first macro-base station a second control message that contains the information of at least one femto-base station (FBS) identifier associated with the at least one CSGID value. The mobile station uses the information of the at least one FBS identifier to access a first femto-base station associated with the at least one FBS identifier.
