Abstract

IP-based Location Services (IP-LCS) is a valuable application that may be supported by a majority of cellular phones in the future. Services offered by such applications can be closely coupled to the location of the user. IP-LCS may be designed to permit a location based application resident on a mobile terminal to track a mobile terminal or a cluster of mobile terminals, or to otherwise provide location based services to a mobile node based on the location of another mobile node or a cluster of mobile nodes.

Claims

1. A method, comprising:

identifying a first node and an entity; and

serving the first node with a service based on a location of the entity,

wherein the method is implemented by a location based application residing on a the first node, and wherein the entity is configured to be a mobile entity.

2. The method of claim 1, wherein the serving the first node comprises providing at least one of a gaming experience to the first node, or a location of the second node to the first node.

3. The method of claim 1, wherein the providing the location of the second entity comprises providing the location of at least one of a second mobile node, a cluster, a pet, a vehicle, an employee, a coworker, a friend, or a family member.

4. The method of claim 1, wherein the serving the first node comprises operating a location based application based on the location of the entity.

5. A method, comprising:

providing a request from a location based application to a mobile node;

forwarding, by the mobile node, the request to a location information platform;

identifying, by the location information platform, a second mobile node from the request;

identifying, by the location information platform, a second location information platform corresponding to the second mobile node;

contacting, by the location information platform, the second location information platform with the request;

obtaining, by the second location information platform location information of the second mobile node; and

providing the location information to the location based application.

6. The method of claim 5, wherein the providing the request comprises providing at least one of an identity of the second mobile node, or authentication information.

7. The method of claim 6, wherein the providing the authentication information comprises providing information for at least one of the location based application or the mobile node.

8. The method of claim 5, further comprising:

configuring the location information platform to also be the second location information platform.

9. The method of claim 5, wherein the identifying the second location information platform comprises contacting at least one of a local domain name server, or a local cache.

10. The method of claim 5, further comprising:

securing the contacting the second location information platform using a trust relationship between a network of the location information platform and a network of the second location information platform.

11. The method of claim 5, wherein the providing the location information comprises

forwarding the location information from the second location information platform to the location information platform,

transferring the location information from the location information platform to the mobile node, and

forwarding the location information from the mobile to the location based application.

12. The method of claim 11, further comprising:

authenticating, by the mobile node, a message containing the location information before forwarding the location information to the location based application.

13. A method, comprising:

receiving a request from a location based application of a mobile node for location information regarding a second mobile node;

identifying a resource for the location information;

obtaining the location information from the resource; and

providing the location information to the location based application.

14. The method of claim 13, further comprising:

performing the obtaining and providing periodically.

16. The method of claim 13, wherein obtaining the location information comprises obtaining the location information directly or indirectly from the second mobile node.

15. The method of claim 15, wherein the performing the obtaining and providing periodically is responsive to the receiving the request periodically.

17. A device, comprising:

a location based application resident on the device; and

a transceiver configured to obtain a location of an entity to activate the location based application,

wherein the device is configured to be mobile, and

wherein the entity is configured to be a mobile node or a cluster.

18. The device of claim 17, wherein the location based application comprises at least one of a multi-player game, or a display of the location of the mobile node.

19. The device of claim 17, wherein the location based application is configured to provide the location of at least one of a pet, a vehicle, an employee, a coworker, a friend, or a family member.

20. The device of claim 17, wherein the device is a mobile terminal.

21. A system, comprising:

a location based application configured to provide a request to a mobile terminal;

the mobile terminal configured to receive the request, and forward the request to an location information platform;

the location information platform configured to receive the request from the mobile terminal, to identify a second mobile terminal from the request, to identify a second location information platform corresponding to the second mobile node, and to contact the second location information platform with the request;

the second location information platform configured to receive the request, obtain location information of the second mobile node, and provide the location information to the location based application.

22. The system of claim 21, wherein the request comprises at least one of an identity of the second mobile node, or authentication information.

23. The system of claim 22, wherein the authentication information comprises information for at least one of the location based application or the mobile node.

24. The system of claim 21, wherein the location information platform is also the second location information platform.

25. The system of claim 21, wherein the location information platform is configured to identify the second location information platform by contacting at least one of a local domain name server or a local cache.

26. The system of claim 21, wherein the location information platform is configured to contact the second location information platform using a trust relationship between a network of the location information platform and a network of the second location information platform.

27. The system of claim 21, wherein the second location information platform is configured to provide the location information by forwarding the location information to the location information platform, wherein the location information platform is configured to transfer the location information to the mobile node, and wherein the mobile node is configured to forward the location information to the location based application.

28. The system of claim 27, wherein the mobile node is configured to authenticate a message containing the location information before forwarding the location information to the location based application.

29. A device, comprising:

a receiver unit configured to receive a request from a location based application of a mobile node for location information regarding a second mobile node;

an identification unit configured to identify a resource for the location information;

an obtainer unit configured to obtain the location information from the resource; and

a provision unit configured to provide the location information to the location based application.

30. The device of claim 29, wherein the obtainer unit and provision unit are configured to operate periodically.

31. The device of claim 29, wherein the obtainer unit and provider unit are configured to operate periodically in response to the receiver unit receiving the request periodically.

32. The device of claim 29, wherein obtainer unit is configured to obtain the location information directly or indirectly from the second mobile node.
