Patent ID: 8897775

Claim:
A method of searching a femtocell access point comprising: transmitting configuration/measurement information including an operating frequency and a transmission power strength determined by measuring a pilot channel signal strength of a base station within a macro cell, from multiple femtocell access points located within the macro cell to an operator spectrum manager (OSM)/cognitive pilot channel (CPC) server; receiving, at the OSM/CPC server, the configuration/measurement information from the femtocell access points, and generating a femtocell access point list usable in a mobile terminal to provide the generated femtocell access point list to the mobile terminal; obtaining, at the OSM/CPC server, a serviceable cell-radius of each femtocell access point which is obtained by using the configuration/measurement information transmitted from each femtocell access point; determining a transmission signal level range of the base station of the macro cell within the serviceable cell-radius; and generating the FAP list by using the configuration/measurement information and the transmission signal level range of the base station; and selecting, at the mobile terminal, one femtocell access point from the femtocell access point list provided from the OSM/CPC server and accessing the selected femtocell access point.
