Abstract

The claimed subject matter relates to systems and methods for processing messages in a wireless communications environment. In an aspect, a communications method is provided. The method includes establishing a communications link though an access component with a network domain node and enabling at least one other communications link through at least one other access component with the network domain node. This also includes enabling concurrent communications with the network domain node via the access component or the other access component.

Claims

1. A communications method for a mobile device, comprising:

establishing a communications link though an access component with a network domain node;

employing at least one other communications link through at least one other access component with the network domain node; and

processing concurrent communications with the network domain node via the access component or the at least one other access component.

2. The method of claim 1, further comprising initiating a subsequent registration through an alternative path with the network domain node.

3. The method of claim 2, further comprising changing sequence information and associating the changed sequence information with the subsequent registration.

4. The method of claim 3, where changing the sequence information involves incrementing a value, decrementing a value, or updating a timestamp value.

5. The method of claim 4, where changing the sequence information is performed by a mobile terminal or a proxy node.

6. The method of claim 1, further comprising processing one or more events or triggers independently of one or more other events or triggers.

7. The method of claim 1, further comprising enabling concurrent communication via predetermined policy or via signaled policy.

8. The method of claim 1, further comprising generating a Proxy Mobile Internet Protocol (PMIP).

9. The method of claim 1, further comprising generating a Networked-Based Localized Mobility Management (NETLMM) protocol.

10. The method of claim 1, further comprising a Local Mobility Anchor to control concurrent communications.

11. The method of claim 1, further comprising performing a link registration through a path that includes at least one access point, access node, or access router.

12. The method of claim 1, further comprising a Quality of Service (QoS) signaling protocol to facilitate concurrent communications channels.

13. The method of claim 1, the QoS signaling is employed to create flow specific routes that point to a link over which a reservation is performed.

14. A communications apparatus, comprising:

a memory that retains instructions to process multiple concurrent link connections in a roaming access terminal, the multiple link connections established via two or more access components and at least one local mobility anchor; and

a processor that executes the instructions.

15. The communications apparatus of claim 14, further comprising a quality of service component to establish the multiple link connections.

16. The communications apparatus of claim 15, further comprising a policy component to facilitate communications over the multiple communications links.

17. A communications apparatus, comprising:

means for receiving multiple link responses from a network domain;

means for processing the link responses; and

means for communicating across multiple communication links in accordance with the link responses.

18. A machine-readable medium having stored thereon machine-executable instructions for:

receiving a request from an access terminal to a network domain;

processing the request across two or more communications links; and

employing one or more policies to control the communications links.

19. The machine-readable medium of claim 18, wherein the instructions further comprise employing one or more quality of service parameters to determine the communications links.

20. The machine-readable medium of claim 18, wherein the instructions further comprise processing one or more triggers independently from at least one other trigger.

21. A processor that executes the following instructions:

processing data across multiple concurrent communications links from a network domain; and

employing Quality of Service parameters or admission control parameters to facilitate communications across the communications links.

22. A communications method for a network domain, comprising:

establishing a communications link though an access component;

enabling at least one other communications link through at least one other access component; and

enabling concurrent communications with a network domain node via the access component or the at least one other access component.

23. The method of claim 22, the network domain node is a local mobility anchor.

24. The method of claim 22, the access component is an access router.

25. The method of claim 22, further comprising processing a link state trigger or a quality of service trigger.

26. The method of claim 22, further comprising registering a link on a link up trigger or deregistering a link on a link down trigger.

27. The method of claim 22, further comprising processing multiple communications links as alternative links that send message flows to one or more communications links.

28. The method of claim 22, further comprising initiating a flow-specific registration in view of a quality of service request.

29. The method of claim 22, further comprising performing a flow-specific deregistration.

30. The method of claim 22, further comprising processing multicasting requests or unicast requests.

31. The method of claim 22, further comprising employing a context transfer component to communicate with other existing links.

32. A communications apparatus, comprising:

a memory that retains instructions to create multiple concurrent link connections in a roaming access terminal, the multiple link connections established via two or more access components and at least one local mobility anchor; and

a processor that executes the instructions.

33. A communications apparatus, comprising:

means for generating multiple link responses from a network domain;

means for processing the link responses; and

means for communicating across multiple communication links in accordance with the link responses.

34. A machine-readable medium having stored thereon machine-executable instructions for:

receiving a response to a link request from a network domain;

processing the request across two or more communications links; and

employing one or more policies to control the communications links.

35. A processor that executes the following instructions:

generating multiple concurrent communications links from a network domain; and

processing Quality of Service parameters or admission control parameters to route communications across the communications links.
