Abstract
Handoff configuration information is provided to a dual mode Access Terminal (AT) operable to communicate both in a Circuit Switched network domain and a IP Multimedia Subsystem (IMS) network domain. Up-to-date handoff configuration information is transmitted during a registration of the dual mode AT with an IMS network or, alternatively during establishment of a call session of the dual mode AT. An IMS server assigns and sends the handoff configuration information to the dual mode in a response message to a registration request or, alternatively in a request for a call session establishment and in a response message to the request for the call session establishment. The handoff configuration information is used in a call handoff of an ongoing call of the dual mode AT between the CS network and the IMS network. In the examples, the handoff configuration information includes a handoff number for use in a handoff to the Circuit Switched (CS) network and a handoff Uniform Resource Identifier (URI) for use in a handoff to the IMS network.
