Abstract:
A method for determining the geographic location of at least one wireless device, comprising:a) receiving a first set of location information at the at least one wireless device from a location computation entity, comprising: i) receiving at a network subsystem the first set of location information from the location computation entity; ii) sending from the network subsystem the first set of location information to a first base station subsystem; and iii) sending from the first base station subsystem the first set of location information to the at least one wireless device; b) sending a second set of location information, said second set of location information relating to the geographic location of the at least one wireless device, to the location computation entity, comprising: i) receiving at the first base station subsystem the second set of location information from the at least one wireless device; ii) sending from the first base station subsystem the second set of location information to the network subsystem; and iii) sending from the network subsystem the second set of location information to the location computation entity; c) receiving a third set of location information in at least one location measurement entity from the location computation entity, comprising: i) receiving at a second base station subsystem the third set of location information from the location computation entity; and ii) sending from the second base station subsystem the third set of location information to the at least one location measurement entity; d) sending a fourth set of location information to the location computation entity, comprising: i) receiving at the second base station subsystem the fourth set of location information from the at least one location measurement entity; and ii) sending from the second base station subsystem the fourth set of location information to the location computation entity; and e) processing the second set of location information, the fourth set of location information or the second and fourth sets of location information at the location computation entity to obtain the geographic location of the at least one wireless device.
