摘要：
A node in an IMS network receives circuit switched signalling relating to a communication session sent from a terminal over a circuit switched access network, and also receives packet switched signalling relating to the communication session sent from the terminal over a packet switched access network. The packet switched signalling comprises an identifier, and the node uses the identifier to correlate the circuit switched signalling with the packet switched signalling. This allows terminals using ICS to send signalling over both packet switched and circuit switched access networks, and a receiving node to correlate those signals.
