System and Method for Mobile Location By Proximity Detection
First Claim
1. A method for determining a location of a mobile device operating in a wireless communications network having an assisted global positioning system (A-GPS) positioning determining entity (PDE), the method comprising the steps of:
- (a) receiving a location request for the mobile device;
(b) determining if the request is for a region in the network having a proximity detection system;
(c) if the region has a proximity detection system, then tasking both the proximity detection system and the A-GPS PDE to determine a location of the mobile device,(i) if at least one of the proximity detection system and the A-GPS PDE provide a location result for the mobile device, then determining the uncertainty of the respective location result and returning the location result having the lowest uncertainty as the location for the mobile device, and(ii) if neither the proximity detection system nor the A-GPS provide a location result for the mobile device, then using a cell-identification as the location for the mobile device; and
(d) if the region does not have a proximity detection system, then tasking the A-GPS PDE to determine a location of the mobile device,(i) if the A-GPS PDE provides a location result for the mobile device, using this location result as the location for the mobile device, and(ii) if the A-GPS does not provide a location result for the mobile device, then using a cell-identification as the location for the mobile device.

Abstract
A system and method for determining a location of a mobile device operating in a wireless communications network having an assisted global positioning system (A-GPS) positioning determining entity (PDE). A location request may be received for the mobile device. The location of the mobile device may be determined as a cell identification location if no location results are received from either the A-GPS PDE or a proximity detection system PDE, or the location of the mobile device may be determined as a location result from the A-GPS PDE if the A-GPS PDE provides a location result having a lower uncertainty than a location result from the proximity detection system PDE, or the location of the mobile device may be determined as a location result from the proximity detection system PDE if the proximity detection system PDE provides a location result having a lower uncertainty than a location result from the A-GPS PDE.
