20100118832 | Method for connection termination in mobile IP - A method is provided for optimizing the sending of a Mobile IP Revocation Reply. According to the invention methodology, a Foreign Agent operating as the care-of address for a given mobile unit will send to the Home Agent for that mobile unit a Revocation Acknowledgement message immediately after receiving a Revocation message from the Home Agent, without awaiting the conclusion of the Foreign Agent's tear-down steps. After sending that immediate acknowledgement to the Home Agent, the Foreign Agent independently proceeds with its regular procedures of forwarding the Revocation message to the client (as needed), waiting for a response from the client (including retransmitting the request to the client on a timer if no response received), and tearing down the user plane. With the method of the invention, the latency of the latter procedures would not result in a delay in sending the Revocation Acknowledgement from the Foreign Agent to the Home Agent. | 05-13-2010 |
