Abstract

A method for providing accurate geolocation information is described in which geolocation information is received from a plurality of position information sources. A confidence indicator value is associated with each of the plurality of position information sources. Geolocation information received from two or more of the plurality of position information sources is combined based on the confidence value associated with each of the plurality of position information sources. A geolocation accuracy indicator (e.g., a graphical indicator) is provided to a user.

Claims

1. A method for providing accurate geolocation information, the method comprising the steps of:

receiving geolocation information from a plurality of position information sources;

associating a confidence indicator with each of the plurality of position information sources;

combining the geolocation information received from two or more of the plurality of position information sources based on the confidence indicator associated with each of the plurality of position information sources; and

providing a geolocation accuracy indicator.

2. The method of claim 1, wherein the received geolocation information comprises a plurality of position estimate values.

3. The method of claim 1, wherein the received geolocation information is associated with a plurality of observed mobile user equipment communication events.

4. The method of claim 3, wherein the confidence indicator is determined based on the plurality of observed mobile user equipment communication events.

5. The method of claim 1, wherein at least one of the plurality of position information sources comprises a WiFi fingerprinting source.

6. The method of claim 1, wherein at least one of the plurality of position information sources comprises a satellite navigation system.

7. The method of claim 1, wherein the received geolocation information is determined based on one or more device measurement reports.

8. The method of claim 7, wherein the one or more measurement reports comprise timing advance information.

9. The method of claim 7, wherein the confidence indicator is determined based on a number of measurement reports utilized to determine the received geolocation information.

10. The method of claim 1, wherein combining the geolocation information comprises identifying a most likely position based on the confidence indicator.

11. The method of claim 1, wherein the geolocation accuracy indicator identifies a predefined degree of accuracy.

12. The method of claim 7, wherein the geolocation accuracy indicator is a visual indicator presented to a user.

13. The method of claim 7, wherein the geolocation accuracy indicator comprises a color coded visual indicator.

14. A computer program product for providing accurate geolocation information, the computer program product comprising:

one or more computer-readable storage devices and a plurality of program instructions stored on at least one of the one or more computer-readable storage devices, the plurality of program instructions comprising;

program instructions to receive geolocation information from a plurality of position information sources;

program instructions to associate a confidence indicator with each of the plurality of position information sources;

program instructions to combine the geolocation information received from two or more of the plurality of position information sources based on the confidence indicator associated with each of the plurality of position information sources; and

program instructions to provide a geolocation accuracy indicator.

15. The computer program product of claim 14, wherein the program instructions to receive geolocation information comprise program instructions to receive a plurality of position estimate values.

16. The computer program product of claim 14, wherein the received geolocation information is associated with a plurality of observed mobile user equipment communication events.

17. The computer program product of claim 16, wherein the confidence indicator is determined based on the plurality of observed mobile user equipment communication events.

18. The computer program product of claim 14, wherein at least one of the plurality of position information sources comprises a WiFi fingerprinting source.

19. The computer program product of claim 14, wherein at least one of the plurality of position information sources comprises a satellite navigation system.

20. The computer program product of claim 14, wherein the geolocation accuracy indicator comprises a color coded visual indicator.
