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 benchmarking location determination capabilities with a mobile communications device, the method comprising:

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

electronically generating a second set of data to trigger identification of the location of the device using a second technique;

electronically calculating the location of the device using the second technique, responsive to the generated second set of data;

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

storing at least a subset of the first set of data and the third set of data; and

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

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

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

4. The method of claim 1, wherein the electronically calculating the location of the device 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 a location of the device comprises GPS coordinate data.

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

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

8. The method of claim 1, further comprising executing an application on the mobile communications device to generate the second set of data to trigger identification of the location of the 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 one or more of the group consisting of location identification based on cellular network towers, and location identification based on network access points.

11. The method of claim 1, wherein the electronically associating the at least a subset of the first set of data with the third set of data comprises comparing the at least a subset of first set of data and the third set of data, and their associated timestamps to determine an accuracy, latency period, or yield attributable to the calculated location of the device using the second technique.

12. The method of claim 1, further comprising:

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

electronically calculating the second location of the device using said second technique;

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

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

13. The method of claim 1, further comprising:

electronically receiving a fourth set of data identifying a location of a second mobile communications device determined with said first technique;

electronically calculating the location of the second device using said second technique;

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

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

14. A method of benchmarking location determination capabilities of multiple communications networks, the method comprising:

electronically receiving a first set of data identifying a first location of a first mobile device in a first communications network determined with a first technique;

electronically calculating the first location of the first mobile device in said first communications network using a second technique;

electronically generating a second set of data representative of the calculated first location;

electronically receiving a third set of data identifying a second location of a second mobile device in a second communications network determined with said first technique;

electronically calculating the second location of the second mobile device in said second communications network using said second technique;

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

electronically associating at least a subset of the first set of data with the second set of data and at least a subset of the third set of data with the fourth set of data to generate benchmarking data for said first and second communications networks.

15. The method of claim 14, wherein the first mobile device and the second mobile device are the same device.

16. The method of claim 14, wherein the first mobile device and the second mobile device are different devices.

17. The method of claim 14, wherein the first technique comprises utilizing GPS data.

18. The method of claim 14, 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.

19. The method of claim 14, wherein the second technique comprises one or more of the group consisting of location identification based on cellular network towers, and location identification based on network access points.

20. The method of claim 14, wherein the associating comprises comparing the at least a subset of first set of data, the second set of data, the at least a subset of third set of data, the fourth set of data and their associated timestamps to determine an accuracy, latency period, or yield attributable to said first and second communications networks.
