    摘要: An apparatus and method for providing mobility to IMS sessions comprising connecting to an APN through a 3GPP access; determining if a non-3GPP access is available; determining if the APN is specific to an IMS application being used or desired to be used, or if an IP header of an IMS application flow matches a configured pattern; and performing one of: a) triggering an IMS Session Continuity flow through the non-3GPP access for the IMS application based on one of the following: if the APN is specific to the IMS application or if the IP header of the IMS application flow matches the configured pattern; or b) triggering an IP mobility flow through the non-3GPP access for the IMS application or a non-IMS application if the APN is not specific to the IMS application and if the IP header of the IMS application flow does not match the configured pattern.

    摘要: Techniques for supporting handoff of terminals between a packet-switched network and a circuit-switched network are described. In an aspect, handoff between packet-switched and circuit-switched networks may be facilitated by a designated network entity in the packet-switched network. The designated network entity may interface with both the packet-switched network and the circuit-switched network, perform circuit-switched call origination, and perform handoff procedure. In one design, a first terminal may communicate with the packet-switched network for a packet-switched call with a second terminal. The first terminal may initiate handoff to the circuit-switched network via the designated network entity. The first terminal may perform handoff from the packet-switched network to the circuit-switched network based on an inter-MSC handoff procedure. The first terminal may then communicate with the circuit-switched network for the circuit-switched call with the second terminal after the handoff.
