ABSTRACT:
Various aspects are disclosed herein for determining a location estimate for multi-mode mobile devices using measurements from one or more radio access technologies and providing a combined location solution. Using the multiple radio access technology capability of the wireless communications system, a mobile communications device may be located on a first radio network characterized by a first radio modulation technique, radio network topology, and channel bandwidth. The mobile communications device may then be handed off to a second radio network and located using a second radio network characterized by a second radio modulation technique, radio network topology, and channel bandwidth. The two location estimates may then be used to develop a combined location estimate.
