Circuit-switched and multimedia subsystem voice continuity

A node for providing a continuity control function comprising:

• A communication interface;
• and
• A control system associated with the communication interface and adapted to:
• provide a signaling anchor point in a multimedia subsystem for a first access signaling leg and a remote access signaling leg for a call between a user element and a remote endpoint, the first access signaling leg provided for the user element via a transferring-out subsystem;
• establish a second access signaling leg toward a user element via a transferring-in subsystem;
• replace the first access signaling leg with the second access signaling leg, such that the second access signaling leg is anchored at the signaling anchor point;
• and
• provide call signaling via the second access signaling leg and the remote signaling leg to transfer at least a portion of a bearer path connected to the user element from a first network to a second network.
