Internet protocol version 4 support for proxy mobile internet protocol version 6 route optimization protocol
First Claim
1. 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, andwherein 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, andwherein the early PBU and the PBAck are not received by the MN.

Abstract
A network component comprising at least one processor configured to implement a method comprising promoting an optimization of a communications route associated with a mobile node (MN) and a correspondent node (CN) using Internet Protocol version 4 (IPv4) packets is disclosed. Also disclosed is a network comprising a mobility access gateway (MAG) in communication with a MN, and a CN in communication with the MAG and that desires to communicate with the MN, wherein a communications route between the MN and the CN is optimized using IPv4 signaling. Included is a method comprising promoting an optimization of a communications route between a MN and a CN using IPv4 signaling. Standalone CNs and CNs under a MAG embodiments are supported.

3. A network comprising:
-
a mobility access gateway (MAG) in communication with a mobile node (MN); and a correspondent node (CN) in communication with the MAG and that desires to communicate with the MN, a first local mobility anchor (LMA) in communication with the MAG and the CN; a second LMA in communication with the LMA; and a second MAG in communication with the CN and the second LMA, wherein a communications route between the MN and the CN is optimized 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 optimizing the communications route further comprises using a proxy home test (PHoT) procedure comprising IPv4 signaling, wherein the LMA and the MAG are associated with the MN, wherein the second LMA and the second MAG are associated with the CN, wherein the MAG, the first LMA, the second LMA, and the second MAG participate in the PHoT procedure, and wherein the first LMA and the second LMA do not participate in the PCoT procedure. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. An apparatus comprising:
-
a processor coupled to a memory and configured to; perform a proxy care-of test (PCoT) procedure and/or a proxy home test (PHoT) procedure to optimize a communications route between a mobile node (MN) and a correspondent node (CN), wherein neither the PCoT procedure nor the PHoT procedure comprise signaling the MN, wherein the PCoT procedure is performed to validate the MN'"'"'s care-of-address (CoA), and wherein performing the PCoT procedure comprises; sending an early proxy binding update (PBU) to either the CN or the CN'"'"'s media access gateway (MAG), wherein the early PBU comprises a Care-of-Test (CoT) init (CoTI) option; and receiving a proxy binding acknowledgment (PBAck) from either the CN or the CN'"'"'s MAG, wherein the PBAck comprises a care-of-keygen token, and wherein the early PBU and the PBAck are not received by the MN. - View Dependent Claims (13, 14, 15)
