Abstract
A hybrid system and method are provided for determining the geographic location of a wireless device. A first base station subsystem is connected to the wireless device for transferring location information to and from the wireless device. A network subsystem is connected to the first base station subsystem and to a location computation entity for transferring location information between the first base station subsystem and the location computation entity. A second base station subsystem is connected to a location measurement entity and to the location computation entity for transferring location information between the location measurement entity and the location computation entity. The location computation entity generates and sends location information to the wireless device and/or location measurement entity and processes location information received from the wireless device and/or location measurement entity to obtain the geographic location of the wireless device.
