Patent ID: 8228843

Claim:
A network component comprising: at least one processor configured to: optimize a communications route associated with a mobile node (MN) and a correspondent node (CN) using a proxy care-of test (PCoT) procedure comprising Internet Protocol (IP) version 4 (IPv4) signaling, wherein the communications route is optimized without signaling the MN, wherein the network component is a mobility access gateway (MAG) that serves the CN, and wherein optimizing the communications route comprises: receiving an early proxy binding update (PBU) from a second MAG serving the MN, wherein the early PBU comprises a Care-of-Test (CoT) init (CoTI) option; and sending a proxy binding acknowledgment (PBAck) to the second MAG, wherein the PBAck comprises a care-of-keygen token, and wherein the early PBU and the PBAck are not received by the MN.
