1. A method for registering a mobile node on a foreign network during a hand-off transition comprising:
at a node of a home network:
receiving a pre-handoff registration request message after the mobile node has initiated a connection to said foreign network but prior to completion of a hand-off to the foreign network, said pre-handoff registration request message including a lifetime time period indicator;
after processing the pre-handoff registration request, transmitting a registration response confirming the pre-handoff registration for the transitional lifetime time period; and
using the provisional care-of address to process communication packets associated with the mobile node.
