System, apparatus, and method for distributed home agents in a mobile IP environment

摘要

Included is an apparatus comprising a first network node in a first network configured to act as a home agent (HA) for a mobile node (MN), wherein the first network is one of a plurality of networks that connect to the MN, and wherein a second network that connects to the MN comprises a second network node configured to act as a second HA for the MN. Also included is a method comprising receiving, by a first network node, a binding update message, wherein the first network node is in a first network, and wherein the first network node is configured to act as a HA for a MN; and sending, by the first network node, a binding acknowledgement, wherein the binding update message comprises a multicast state of the MN.

1. An apparatus positioned in a local network comprising: a transmitter; a receiver; and a processor coupled to the transmitter and receiver and configured to cause the apparatus to: negotiate a connection with a mobile node (MN); selectively act as a local home agent (HA) in the local network only for MN flows initiated while the MN is connected to the local network, wherein the local network is not a home network for the MN, wherein acting as a local HA comprises managing control signaling for the MN and not managing data signaling for the MN, and wherein managing control signaling comprises managing binding registrations for the MN; and forward communications regarding MN flows that are not initiated while the MN is connected to the local network to a foreign HA in a foreign network.
