MOBILITY SUPPORT FOR MULTIHOME NODES

摘要

A method, a correspondent node and a mobile node are provided for allowing setup of a session between the mobile node and the correspondent node using a new unique indicator in lieu of the home address to enable the correspondent node to uniquely identify the mobile node. The correspondent node uses the new unique indicator to identify the session within its Binding Cache Entry table. The mobile node may change its selection of a home address without impacting its ongoing session. Change of a home address may occur when the mobile node selects a new home agent to serve an ongoing session, or when the mobile node selects a new access interface during an ongoing session.
