In a system and method for handing off a mobile node in a seamless manner
in a wireless access network, procedures are implemented for allowing the
mobile node to synchronize the handoff with a base node (e.g., a home
agent) and a correspondent node. In this way, a seamless handoff may be
achieved, since few or no data packets sent between the base node or the
correspondent node and the mobile node are lost. The procedures are
supported by both Mobile IPv4 and Mobile IPv6 as well as Hierarchical
Mobile IPv4 and Hierarchical Mobile IPv6.
