1. An apparatus in a communication network, comprising:
- a memory;
a processor coupled to said memory; and
circuitry coupled to at least one of said processor or said memory and cooperatively configured to act as a proxy entity on behalf of an end node during a time when said end node is inaccessible for communications, wherein the apparatus, acting as the proxy entity, is configured to create and send first packets to a correspondence node on behalf of the end node, function as a network end point for second packets that are addressed to a home address of the end node, and process application data within the second packets as if the proxy entity were the end node.

Abstract
Methods and apparatus for extending Mobile IP to enable a Mobile IP Home Agent to forward to a default proxy MN server when it does not have a current binding for a MN home address. This can be used to route traffic when the MN is absent and to add processes onto the Proxy MN server that enables application intelligence at the Proxy MN server to act on behalf of the MN when the MN so wishes, e.g., substituting for the MN while the MN is in sleep mode or otherwise unavailable.

12. A wireless apparatus in a communication network, comprising:
-
a processor; and circuitry coupled to said processor cooperatively configured to inform an entity in said communication network as a proxy entity to act on behalf of said wireless apparatus during the time when said wireless apparatus is inaccessible for communications, wherein acting on behalf of said wireless apparatus comprises creating and sending first packets to a correspondence node on behalf of the wireless apparatus, functioning as a network end point for second packets that are addressed to a home address of the wireless apparatus, and processing application data within the second packets as if the proxy entity were the wireless apparatus. - View Dependent Claims (13, 14, 15, 16, 17)

18. An infrastructure apparatus serving as an access node in a communication network, comprising:
-
a memory; a processor coupled to said memory; and circuitry coupled to at least one of said processor or said memory and cooperatively configured to coordinate a proxy entity to act on behalf of an end node during a time when said end node is inaccessible for communications, wherein the infrastructure apparatus, acting on behalf of the end node, is configured to create and send first packets to a correspondence node on behalf of the end node, function as a network end point for second packets that are addressed to a home address of the end node, and process application data within the second packets as if the proxy entity were the end node. - View Dependent Claims (19, 20, 21, 22)

23. A wireless communication method operable by a communication node in a communication system having an access node and an end node, comprising:
-
communicating with said access node; and acting as a proxy entity on behalf of said end node in response to a message in communicating with said access node, wherein acting as the proxy entity comprises creating and sending first packets to a correspondence node on behalf of the end node, functioning as a network end point for second packets that are addressed to a home address of the end node, and processing application data within the second packets as if the proxy entity were the end node.
