Abstract

Systems, methods, and software are described for benchmarking the location determination capabilities of a wireless communications network. A mobile communications device is configured to receive data identifying a reference location for the device. A communications network, communicatively coupled with the mobile communications device, calculates a computed location for the device using an alternative location determination technique. The reference location and computed location may be determined for any number of additional devices, as well. The accuracy and reliability of a system may then be assessed by comparing one or more computed locations with associated reference locations. The latency attributable to the calculation of one or more computed locations may also be determined.

Claims

1. A method of associating location data in a communications network, the method comprising:

electronically receiving a first set of data related to a location determined with a first technique;

electronically calculating the same location using a second technique;

electronically generating a second set of data representative of the calculated location using the second technique; and

electronically associating at least a subset of the first set of data with the second set of data to generate data for the communications network, wherein the electronically associating comprises electronically comparing the at least a subset of first set of data and the second set of data, and their associated timestamps to determine an accuracy, latency period, or yield attributable to the calculated location using the second technique.

2. The method of claim 1, wherein the location is a location of a mobile device, and wherein calculating the location using the second technique is performed by the mobile device.

3. The method of claim 1, wherein electronically calculating the location using the second technique is performed by the communications network.

4. The method of claim 1, wherein electronically calculating the location using the second technique is performed by a location server of a service provider coupled to the communications network.

5. The method of claim 1, wherein the first set of data identifying the location comprises GPS coordinate data.

6. The method of claim 1, wherein the first set of data identifying the location comprises location information specific to a current location of a mobile device.

7. The method of claim 6, wherein said location information specific to a current location of the mobile communications device is location data specific to a building.

8. The method of claim 1, further comprising executing an application on a mobile device to generate triggering data to trigger identification of the location of the mobile device.

9. The method of claim 1, wherein the second technique comprises one or more of the group consisting of assisted GPS, time difference of arrival, time of arrival, angle of arrival, RF Fingerprinting, and location pattern matching.

10. The method of claim 1, wherein the second technique comprises location identification based on network access points.

11. The method of claim 1, further comprising:

electronically receiving a third set of data identifying a second location of the device determined with said first technique;

electronically calculating the second location using said second technique;

electronically generating a fourth set of data representative of the calculated second location using said second technique;

electronically associating the at least a subset of the third set of data with the fourth set of data to generate data for a second communications network.

12. The method of claim 1, further comprising:

electronically receiving a third set of data identifying a second location determined with said first technique;

electronically calculating the second location using said second technique;

electronically generating a fourth set of data representative of the calculated second location using said second technique;

electronically associating the at least a subset of the third set of data with the fourth set of data to generate data for a second communications network.
