Abstract
A method and system for handover of a mobile station (MS) to an unlicensed mobile access network controller (UNC) in an unlicensed mobile access network (UMAN). In one embodiment, the MS sends an unlicensed mobile access (UMA) radio resource (URR) Registration Request message to the UNC with one or more location identifiers for the MS. The location identifiers may include a GSM Cell Global Identity, an access point (AP) Radio Identity, a set of GPS coordinates, or an AP location. The UNC selects absolute radio frequency channel numbers (ARFCN) and base station identity codes (BSIC) values from a table based on the location identifiers and returns them to the MS in a URR Registration Accept message.
