Abstract

A network access server, such as a PDSN, might provide Mobile IP services to one or more access points for a wireless wide area network. A wireless device might handoff to an access point served by the network access server, and the wireless device might receive from the access point an identifier, such as a Packet Zone ID, that identifies the network access server. The wireless device might then register with the access server but delay making any subsequent Mobile IP re-registrations until after a predetermined amount of time.
