Abstract
A system for providing seamless interoperability for a multi-hyperband capable mobile station roaming between cells within a cellular telecommunications network having a mobile switching center and a plurality of base stations that transmit and receive radio signals in a plurality of frequency hyperbands. The system comprises a plurality of location and verification devices within each of the plurality of base stations, Each of the plurality of location and verification devices operates in a different one of the plurality of frequency hyperbands. The system builds a neighbor list of candidate cells for handoff that includes cells operating in different ones of the plurality of frequency hyperbands, identifies the best candidate cell for communication with the mobile station, and verifies the presence of the mobile station in the identified candidate cell.
