First Claim
Patent Images
1. A method in a computing system of determining a geographic location associated with a wireless mobile device accessing a data network, the method comprising:
- receiving a request for a location of a wireless mobile device that is connected to the data network through an access point operating on unlicensed frequency spectrum,wherein the request includes a location accuracy requirement;
determining an estimated location of the wireless mobile device by accessing stored location information;
providing the estimated location in a first response to the request for the location of the wireless mobile device; and
when the provided estimated location fails to meet the location accuracy requirement, thendetermining a GPS location of the wireless mobile device by using information derived from global positioning system (GPS) signals; and
providing the GPS location of the wireless mobile device in a second response to the request for the location of the wireless mobile device.

Abstract
A system and method for mitigating the delay associated with using GPS technologies to determine the location of a mobile device. The system utilizes a two-stage location determination process. During the first stage, an estimated position of the mobile device is immediately provided based on the most accurate stored location information that is available to the system. If greater accuracy is still required, during the second stage a more accurate position of the mobile device is provided using GPS-based technologies.

13. A system for determining a geographic location associated with a mobile device that is wirelessly accessing a data network, the system comprising:
-
a first location estimator configured to provide an estimated location of a mobile device that is accessing the data network via an access point operating on unlicensed frequency spectrum, wherein the first location estimator is configured to determine the estimated location of the mobile device by accessing stored location information, and wherein the first location estimator is configured to provide the estimated location in a first response to a request for a position of the mobile device; and a second location estimator configured to provide a GPS location of the mobile device, wherein the second location estimator is configured to initiate a communication with the mobile device that causes the mobile device to calculate its GPS location using information derived from global positioning system (GPS) signals and communicate the GPS location to the second location estimator, wherein the second location estimator is configured to provide the GPS location in a second response to the request for the position of the mobile device, and wherein the second location estimator is utilized when the provided estimated location fails to meet a location accuracy requirement. - View Dependent Claims (14, 15, 16, 17, 18)
