Abstract:
1. A method for operating a base station, comprising: providing wireless service to wireless devices in a coverage area; transacting a call with a wireless device; receiving, at the base station, information indicative of a pilot code detected by the wireless device, the pilot code being shared by multiple Femto Access Points (FAPs) that each provide wireless service in at least a portion of the coverage area such that information indicative of the pilot code cannot unambiguously identify to the base station an FAP that transmitted the pilot code detected by the wireless device; receiving, at the base station, information indicative of an identification sequence detected by the wireless device, wherein the identification sequence is transmitted by an FAP from the multiple FAPs that share the pilot code, the FAP being different from the base station, and wherein the wireless device receives the identification sequence over periods of time that are different from time periods over which the pilot code is received; using the information indicative of the identification sequence to identify one of the FAPs that share the pilot code; and performing a hand-off of the call to the identified FAP to continue to provide wireless service for the call via the identified FAP.
