Abstract
A telecommunications network has a packet switched domain for handling packet based calls and a circuit switched telephony domain for handling circuit switched calls. A node of the packet switched telephony domain decides whether to terminate a call to a user equipment using a packet based connection to the user equipment or using a circuit switched connection to the user equipment. In response to deciding to terminate the call using the circuit switched connection, the node sends, to a further node controlling routing of calls between the packet switched telephony domain and the circuit switched telephony domain, an indication that services related to the call are controlled in the packet switched telephony domain. In accordance with the indication, the further node may then adapt its control signalling with respect to a node of the circuit switched telephony domain.
