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 includes 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, comprising:

a CPU, a computer readable memory and a computer readable storage medium;

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; and

third program instructions to cache the user location information,

wherein the first, second, and third program instructions are stored on the computer readable storage medium for execution by the CPU via the computer readable memory.

2. The system of claim 1, wherein the first, second, and third program instructions are at least one of maintained, deployed, created and supported by a service provider.

3. The system of claim 1, wherein the first, second, and third program instructions periodically update the user location information and provide the updated user location information for storage.

4. The system of claim 1, wherein the first, second, and third program instructions integrate into an IP Multimedia Subsystem (IMS) network.

5. The system of claim 1, wherein the first, second, and third program instructions integrate into a legacy network.

6. The system of claim 1, 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.

7. The system of claim 1, wherein the trigger is logging onto the network.

8. The system of claim 1, 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.

9. The system of claim 1, 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.

10. The system of claim 1, wherein the user location information is obtained from one or more users that have opted into the location based service.

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

receive, by a computing device, a network log on request or authentication;

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

store the location information in a cache;

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

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

12. The method of claim 11, wherein the steps of claim 11 are integrated into an IP Multimedia Subsystem (IMS) network which handle authorizations via the Diameter based signaling protocol.

13. The method of claim 11, wherein the steps of claim 11 are integrated into a legacy network.

14. The method of claim 11, wherein the requesting location information of a user is provided prior to a request by the user.

15. The method of claim 11, wherein the requesting location information of a user is periodically updated and refreshed in the cache.

16. The method of claim 11, further comprising providing a low priority refresh of the cache to maintain a quality of the location information of the user
