Abstract
A method and system for locating an unlicensed mobile access (UMA) subscriber. The method enables a user of a mobile station comprising a hand-set or the like that supports voice and data access via both licensed and unlicensed radio spectrums to be located. Accordingly, services requiring location information, such as 911 services, may be accessed when operating the mobile station under both UMA and licensed wireless network (e.g., cellular) sessions.
