Abstract

A method is provided in one example embodiment and includes communicating location and access network information for an end user to a policy and charging rules function (PCRF) element that is coupled to a network element. The network element receives packets for a communications flow from the end user if the flow is initiated through a wireless network and through a wireline network. In more specific embodiments, the location and access network information is used to initiate one or more applications for the end user. The method could also include communicating to an application function that the end user has attached to one of the networks, has been assigned an Internet Protocol (IP) address, and the location and access network information for the end user.

Claims

1. A method, comprising:

communicating location and access network information for an end user to a policy and charging rules function (PCRF) element that is coupled to a network element, the network element receiving packets for a communications flow from the end user if the flow is initiated through a wireless network and through a wireline network.

2. The method of claim 1, wherein the location and access network information is used to initiate one or more applications for the end user.

3. The method of claim 1, further comprising:

communicating to an application function that the end user has attached to one of the networks, has been assigned an Internet Protocol (IP) address, and the location information for the end user.

4. The method of claim 1, further comprising:

receiving a query that asks for the location and access network information; and

providing a response to the query.

5. The method of claim 1, further comprising:

providing an event notification for the network element for the end user.

6. The method of claim 5, wherein the event notification includes an update for the location and access network information.

7. The method of claim 5, wherein the event notification includes an indication of when the end user logs on to the network.

8. An apparatus, comprising:

a policy and charging rules function (PCRF) element that is coupled to a network element, the PCRF communicating location and access network information for an end user, the network element receiving packets for a communications flow from the end user if the flow is initiated through a wireless network and through a wireline network.

9. The apparatus of claim 8, wherein the location and access network information is used to initiate one or more applications for the end user.

10. The apparatus of claim 8, wherein the PCRF communicates to an application function that the end user has attached to one of the networks, has been assigned an Internet Protocol (IP) address, and the location information for the end user.

11. The apparatus of claim 8, wherein the PCRF receives a query that asks for the location and access network information and provides a response to the query.

12. The apparatus of claim 8, wherein the PCRF provides an event notification for the network element for the end user.

13. The apparatus of claim 12, wherein the event notification includes an update for the location and access network information or an indication of when the end user logs on to the network.

14. Logic encoded in one or more tangible media for execution and when executed by a processor operable to:

communicate location and access network information for an end user to a policy and charging rules function (PCRF) element that is coupled to a network element, the network element receiving packets for a communications flow from the end user if the flow is initiated through a wireless network and through a wireline network.

15. The logic of claim 14, wherein the location and access network information is used to initiate one or more applications for the end user.

16. The logic of claim 14, wherein the code is further operable to:

communicate to an application function that the end user has attached to one of the networks, has been assigned an Internet Protocol (IP) address, and the location information for the end user.

17. The logic of claim 14, wherein the code is further operable to:

receive a query that asks for the location and access network information; and

provide a response to the query.

18. The logic of claim 14, wherein the code is further operable to:

provide an event notification for the network element for the end user.

19. The logic of claim 18, wherein the event notification includes an update for the location and access network information or an indication of when the end user logs on to the network.

20. A system, comprising:

means for communicating location information for an end user to a policy and charging rules function (PCRF) element that is coupled to a network element, the network element receiving packets for a communications flow from the end user that can conduct the flow through a wireless network and through a wireline network; and

means for initiating one or more applications for the end user.

21. The system of claim 20, further comprising:

means for communicating to an application function that the end user has attached to the network, has been assigned an Internet Protocol (IP) address, and the location information for the end user.

22. The system of claim 20, further comprising:

means for receiving a query that asks for the location and access network information; and

means for providing a response to the query.

23. The system of claim 20, further comprising:

means for providing an event notification for the network element for the end user.

24. The system of claim 23, wherein the event notification includes an update for the location and access network information or an indication of when the end user logs on to the network.
