Enhanced techniques for using core based nodes for state transfer
First Claim
1. An access node for providing communication of state information. comprising;
- an interface for receiving a request message from an end node; and
a processor coupled with a memory configured to;
search the memory for current state information associated with the end node;
generate an update message based on the request message, wherein the update message includes an end node identifier and a time stamp of the current state information; and
initiate the interface to send the update message to a management node to instruct the management node to update stored state information associated with the end node with the current state information.

Abstract
Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

15. A method for communication of state information, comprising:
-
receiving a request message from an end node; searching in a memory unit for current state information associated with the end node; generating an update message based on the request message, wherein the update message includes an end node identifier and a time stamp of the current state information; and sending the update message to a storage node to instruct the storage node to update stored state information associated with the end node with the current state information. - View Dependent Claims (16, 17, 18, 19, 20)
