Title of Invention	SEAMLESS HANDOFF BETWEEN ACCESS NETWORKS WITH SAVED SESSION INFORMATION
Abstract	More seamless handoff between access networks is achieved by saving session information for each access network upon being handed off from the access network and invoking the saved session information upon being handed back to the access network. An access terminal establishes a first session with a first access network, which may entail performing QoS negotiation with the first access network and setting up packet filters at a packet data gateway. The access terminal exchanges data with the first access network in accordance with the configuration of the first session. The access terminal saves the first session configuration after being handed off to a second access network, establishes a second session with the second access network, and exchanges data with the second access network in accordance with the configuration of the second session. The access terminal uses the saved first session configuration upon being handed back to the first access network.

SEAMLESS HANDOFF BETWEEN ACCESS NETWORKS WITH SAVED SESSION INFORMATION

Abstract

More seamless handoff between access networks is achieved by saving session information for each access network upon being handed off from the access network and invoking the saved session information upon being handed back to the access network. An access terminal establishes a first session with a first access network, which may entail performing QoS negotiation with the first access network and setting up packet filters at a packet data gateway. The access terminal exchanges data with the first access network in accordance with the configuration of the first session. The access terminal saves the first session configuration after being handed off to a second access network, establishes a second session with the second access network, and exchanges data with the second access network in accordance with the configuration of the second session. The access terminal uses the saved first session configuration upon being handed back to the first access network.
