Abstract
The present invention moves service control including call control for a user element from a cellular network to a multimedia subsystem (MS) such as the Internet Protocol (IP) Multimedia Subsystem (IMS). Call control is provided by the MS irrespective of whether the user element is using cellular or WLAN access for the call. Call control for originating and terminating calls in the CS or MS as well as transferring calls between a circuit-switched subsystem (CS) and MS is anchored at a continuity control function (CCF) in the MS. All call signaling for the call is passed through the CCF. The CCF is a service provided in the user elements home MS and anchors the user elements active CS calls and MS sessions to enable active roaming across the CS and MS.
