Abstract

Aspects of a method and system for global position reference map (GPRM) for AGPS are provided. A GPS enabled device may transmit reference location data to a location server and responded with a global position reference map (GPRM) from the location server. The reference location data and/or the received GPRM may comprise reference positions, which may be any identifiable location information, for the GPS enabled device. The reference location data may be formatted via various location identifiers such as a RNC ID, MCC and/or a MNC indicating desired coverage areas for the received GPRM. The reference location data may be a portion of a reference position database inside the GPS enabled device. The reference position database may be updated via the received GPRM. A fast position fix for the GPS enabled device may be achieved by combining AGPS data or LTO AGPS data, and the reference position database.

Claims

1. A method of processing signals, the method comprising:

transmitting reference location data from a GPS enabled device to a location server, wherein said location server determines a global position reference map (GPRM) based on said transmitted reference location data; and

receiving from said location server, said determined global position reference map by said GPS enabled device.

2. The method according to claim 1, wherein said reference location data and/or said determined global position reference map (GPRM) comprises one or more reference positions.

3. The method according to claim 1, comprising determining said reference location data from surrounding base stations, WiFi towers, WiMAX towers, FM stations, and/or TV antenna.

4. The method according to claim 1, comprising determining said reference location data based on satellite data received by said GPS enabled device.

5. The method according to claim 1, wherein said reference location data comprises a location identifier that indicates a coverage area of said determined global position reference map (GPRM).

6. The method according to claim 5, wherein said location server generates said global position reference map (GPRM) based on said location identifier.

7. The method according to claim 1, wherein said reference location data and/or said determined global position reference map (GPRM) is Cell-ID based, RNC (Radio Network Controller) based, MNC (Mobile Network Code) based, and/or MCC (Mobile Country Code) based.

8. The method according to claim 1, wherein at least a portion of said transmitted reference location data is stored within said GPS enabled device.

9. The method according to claim 8, comprising updating said reference location data stored within said GPS enabled device based on said received global position reference map (GPRM).

10. The method according to claim 1, comprising determining a position fix for said GPS enabled device based on AGPS data or long term orbits (LTO) AGPS data, said reference location data and/or said received global position reference map (GPRM).

11. The method according to claim 10, comprising determining said position fix for said GPS enabled device based on said long term orbits (LTO) AGPS data, said reference location data and/or said received global position reference map (GPRM), without a network connection.

12. A system for processing signals, the system comprising:

one or more processors operable to transmit reference location data from a GPS enabled device to a location server, wherein said location server determines a global position reference map (GPRM) based on said transmitted reference location data; and

said one or more processors are operable to receive from said location server, said determined global position reference map (GPRM) by said GPS enabled device.

13. The system according to claim 12, wherein said reference location data and/or said determined global position reference map (GPRM) comprises one or more reference positions.

14. The system according to claim 12, wherein said one or more processors are operable to determine said reference location data from surrounding base stations, WiFi towers, WiMAX towers, FM stations, and/or TV antenna.

15. The system according to claim 12, wherein said one or more processors are operable to determine said reference location data based on satellite data received by said GPS enabled device.

16. The system according to claim 12, wherein said reference location data comprises a location identifier that indicates a coverage area of said determined global position reference map (GPRM).

17. The system according to claim 16, wherein said location server generates said global position reference map (GPRM) based on said location identifier.

18. The system according to claim 12, wherein said reference location data and/or said determined global position reference map (GPRM) is Cell-ID based, RNC (Radio Network Controller) based, MNC (Mobile Network Code) based, and/or MCC (Mobile Country Code) based.

19. The system according to claim 12, wherein at least a portion of said transmitted reference location data is stored within said GPS enabled device.

20. The system according to claim 19, wherein said one or more processors are operable to update said reference location data stored within said GPS enabled device based on said received global position reference map (GPRM).

21. The system according to claim 12, wherein said one or more processors are operable to determine a position fix for said GPS enabled device based on AGPS data or long term orbits (LTO) AGPS data, said reference location data and/or said received global position reference map (GPRM).

22. The system according to claim 21, wherein said one or more processors are operable to determine said position fix for said GPS enabled device based on long term orbits (LTO) AGPS data, said reference location data and/or said received global position reference map (GPRM), without a network connection.
