ABSTRACT:
In one embodiment, a system and method for determining a location of a mobile device are described. A number of different locations for the mobile device is provided using a location determining system. The locations for a number of virtual base stations are determined utilizing the known locations for the mobile device. Then a new location for the mobile device is established based on the determined plurality of locations of the virtual base stations. In one embodiment, a system and method for establishing network references for a first wireless location determining system are described. A plurality of known locations for a mobile device is provided using a second location determining system. Radio signals between the mobile device and base stations of the first wireless location determining system are measured and a plurality of locations for a respective plurality of virtual base stations are determined based on the known locations of the mobile device and the measured radio signals. The determined plurality of locations for the plurality of virtual base stations are then utilized to establish network references for the first wireless location determining system.
