Networks and methods are disclosed for accurately determining the location of a mobile device for a UMA network. When placing a special number call, such as a 9-1-1 call, the mobile device transmits access point identifiers (AP-ID) for a plurality of the access points accessible to the mobile device. A UNC in the UMA network receives the plurality of AP-ID's from the mobile device. The UNC is connected to a location system and transmits the AP-ID's to the location system over the connection. The location system receives the AP-ID's over the connection and queries an access point database that stores a location for each access point registered in the database. The location system then identifies a plurality of locations for the plurality of access points from the access point database, and estimates the location of the mobile device based on the plurality of locations identified for the plurality of access points.
