Abstract:
1. A method for providing call continuity in a mobile communications device configured to communicate over multiple access networks, comprising: determining, during an active circuit-switched session, a handoff condition to a packet-switched network exists; in response, sending a signal to initiate anchoring to a server configured to anchor the active circuit-switched session, wherein the server is a voice call continuity application server (VCC AS); establishing, during the active circuit-switched session, a new circuit-switched session between the mobile communications device and the server anchoring the active circuit-switched session; and transferring a mobile communications device-side media path of the active circuit-switched session to route through the new circuit-switched session at the VCC AS prior to a hand-off of the mobile communications device-side media path of the active circuit-switched session to the packet-switched network.
