Abstract

An Application Program Interface (API) is defined at a requesting terminal. The API provides a common interface between an application program requesting a location for a target mobile terminal and a location server at the requesting terminal. The location server may be integrated into the API or may be a separate entity. The application program executing on the requesting terminal sends a request through the API for the location of the target mobile terminal. Thus, the API hides the positioning technology details and complexities from the requesting application program. The API communicates with a location determining source that determines the location of the target mobile terminal. The location determining source may be the target mobile terminal. Alternatively, the location determining source may be a network location server such as a Gateway Mobile Location Center or Mobile Positioning Center.

Claims

1. A method of providing a mobile terminal location, the method comprising providing a location for a target mobile terminal in an application program interface (API) executing at a requesting terminal.

2. A method of providing a mobile terminal location, the method comprising:

receiving a request for a location of a target mobile terminal from an application program in an application program interface (API) at a requesting mobile terminal;

selecting a location determining source in the API to determine the location of the target mobile terminal;

communicating the request from the API to the selected location determining source;

determining the location of the target mobile terminal;

receiving the location of the target mobile terminal at the API in the requesting terminal; and

providing the location of the target mobile terminal to an application program from the API.

3. The method of claim 2, wherein communicating the request from the API to the selected location determining source uses a messaging service.

4. The method of claim 3, wherein the messaging service is a short messaging service.

5. The method of claim 3, wherein the messaging service is a multimedia messaging service.

6. The method of claim 3, wherein the messaging service is an instant messaging service.

7. The method of claim 2, wherein communicating the request from the API to the selected location determining source uses a protocol.

8. The method of claim 7, wherein the protocol is an Internet protocol.

9. The method of claim 7, wherein the protocol is a hyper-text transfer protocol.

10. The method of claim 2, wherein the API provides a protocol to receive the request from the application program.

11. The method of claim 2, wherein the API provides a protocol to send the request to the location determining source.

12. The method of claim 2, wherein the API provides a protocol to receive the location from the location determining source.

13. The method of claim 2, wherein the API provides a protocol to send the location to the application program.

14. The method of claim 2, wherein the location determining source is the target mobile terminal.

15. The method of claim 2, wherein the location determining source is a network location server.

16. The method of claim 15, wherein the network location server is a gateway mobile location center.

17. The method of claim 15, wherein the network location server is a mobile positioning center.

18. The method of claim 2, wherein the request is sent using a wireless network.

19. The method of claim 2, wherein the request is sent using a cellular telephone network.

20. The method of claim 2, wherein the request is sent using the Internet.

21. An application program interface for providing a mobile terminal location comprising:

computer code configured to;

receive a request for a location of a target mobile terminal from an application program;

select a location determining source to determine the location of the target mobile terminal;

communicate the request to the selected location determining source;

receive the location of the target mobile terminal; and

send the location to the application program.

22. A device for providing a mobile terminal location, the device comprising:

a processor, coupled to a communication interface, that executes an application program and an application program interface (API);

the API, wherein the API comprises computer code configured to;

receive a request for a location of a target mobile terminal from the application program;

select a location determining source to determine the location of the target mobile terminal;

communicate the request to the selected location determining source;

receive the location of the target mobile terminal; and

send the location to the application program; and

the communication interface, wherein the communication interface is configured to;

send the request to the selected location determining source; and

receive the location of the target mobile terminal using the network.

23. The device of claim 22, wherein the computer code of the API communicates the request to the selected location determining source using a messaging service.

24. The device of claim 23, wherein the messaging service is a short messaging service.

25. The device of claim 23, wherein the messaging service is a multimedia messaging service.

26. The device of claim 23, wherein the messaging service is an instant messaging service.

27. The device of claim 22, wherein the computer code of the API communicates the request to the selected location determining source using a protocol.

28. The device of claim 27, wherein the protocol is an Internet protocol.

29. The device of claim 27, wherein the protocol is a hyper-text transfer protocol.

30. The device of claim 22, wherein the computer code of the API is further configured to provide a protocol to receive the request from the application program.

31. The device of claim 22, wherein the computer code of the API is further configured to provide a protocol to send the request to the location determining source.

32. The device of claim 22, wherein the computer code of the API is further configured to provide a protocol to receive the location from the location determining source.

33. The device of claim 22, wherein the computer code of the API is further configured to provide a protocol to send the location to the application program.

34. The device of claim 22, wherein the location determining source is the target mobile terminal.

35. The device of claim 22, wherein the location determining source is a network location server.

36. The device of claim 35, wherein the network location server is a gateway mobile location center.

37. The device of claim 35, wherein the network location server is a mobile positioning center.

38. The device of claim 22, wherein the request is sent using a wireless network.

39. The device of claim 22, wherein the request is sent using a cellular telephone network.

40. The device of claim 22, wherein the request is sent using the Internet.

41. A system for providing a mobile terminal location, the system comprising:
