Abstract
In general, the present invention provides for a direct inter-subsystem transfer of an active communication session, such as a call, between a packet subsystem (PS) and a circuit-switched subsystem (CS) in an efficient and effective manner while maintaining service control and continuity. Further, the inter-subsystem transfer may take place between a PS of one generation and a CS of another generation.
