Abstract

A system and method is provided for reducing latency when providing user location information services. The system is implemented in a computer infrastructure which comprises computer executable code tangibly embodied on a computer readable medium. The executable code is operable to trigger a location based service to obtain user location information prior to the user registering for location services.

Claims

1. A system implemented in a computer infrastructure comprising computer executable code tangibly embodied on a computer readable medium and being operable to trigger a location based service to obtain user location information prior to the user registering for location services.

2. The system of claim 1, wherein the computer executable code is operable to periodically update the user location information without a request for the location services by the user and store the updated user location information.

3. The system of claim 1, wherein the computer executable code is operable to save the user location information in a cache for use when the user requests the location services.

4. The system of claim 1, wherein the computer executable code is operable to integrate into an IP Multimedia Subsystem (IMS) network and handle authorization via the Diameter based signaling protocol.

5. The system of claim 1, wherein the computer executable code is operable to integrate into a legacy network.

6. The system of claim 1, wherein the computer executable code is operable to establish a connection to a location platform for obtaining the user location information upon a triggering event.

7. The system of claim 6, wherein the triggering event is the user logging onto a network prior to registering for the location services.

8. The system of claim 1, wherein the computer executable code is operable to register user profiles as an opt in service.

9. The system of claim 1, wherein the computer executable code is at least one of maintained, deployed, created and supported on a computing infrastructure by a service provider.

10. The system of claim 1, wherein the computer executable code is operable to refresh the user location information at period intervals.

11. A system, comprising:

first program instructions to register a user with a network or service provider;

second program instructions to trigger a location platform to obtain user location information prior to a user request;

third program instructions to cache the user location information;

a computer readable media which stores the first, second and third program instructions; and

a central processing unit to execute the first, second and third program instructions.

12. The computer program product of claim 11, wherein the first, second and third program instructions are at least one of maintained, deployed, created and supported by a service provider.

13. The computer program product of claim 11, wherein the second program instructions periodically updates the user location information and provides the updated user location information for storage.

14. The computer program product of claim 11, wherein the first, second and third program instructions integrate into an IP Multimedia Subsystem (IMS) network.

15. The computer program product of claim 11, wherein the first, second and third program instructions integrate into a legacy network.

16. The computer program product of claim 11, wherein the first and second program instructions are resident on a home location register and the user location information is stored on at least one of the home location register and the location platform.

17. The computer program product of claim 11, wherein the trigger is logging onto the network.

18. The computer program product of claim 11, further comprising fourth program instructions to receive a request by the user for location services and to provide the location services using the stored user location information.

19. The computer program product of claim 11, wherein:

the first program instructions to register a user with a network includes authenticating the user on a diameter server;

the second program instructions to trigger a location platform to obtain user location information prior to a user request is requested by the diameter server; and

the third program instructions to cache the user location information includes providing a notification to a location service provider.

20. A method for providing location information provided on a computer infrastructure, comprising:

receiving a network log on request or authentication;

requesting location information of a user upon receipt of the network log on request or authentication;

storing the location information in a cache;

receiving a request for location based services from the user; and

retrieving the location information from the cache and using the location information to deliver composite services, of which the location information is a component.

21. The method of claim 20, wherein the steps of claim 20 are integrated into an IP Multimedia Subsystem (IMS) network which handle authorizations via the Diameter based signaling protocol.

22. The method of claim 20, wherein the steps of claim 20 are integrated into a legacy network.

23. The method of claim 20, wherein the requesting location information of a user is provided prior to a request by the user.

24. The method of claim 20, wherein the requesting location information of a user is periodically updated and refreshed in the cache.
