Abstract
There is proposed a method and corresponding apparatuses allowing a change from a packet switched communication domain to a circuit switched communication domain. When a user equipment as a connection terminating point receives a connection initialization message with a media flow, such as audio, which cannot be delivered by the packet switched access, it sends a specific response rejecting the connection via the packet switched access to an application server for service centralization and continuity. In the application server, it is checked whether several conditions are met in order to determine whether the communication connection comprising the media flow is allowed to be changed to the circuit switched domain. If yes, the communication connection is changed from the packet switched communication domain to the circuit switched communication domain.

42. An apparatus comprising:
-
a transmitter configured to transmit a connection initialization request message to a communication connection terminating node for initializing a communication connection in a first communication domain; a receiver configured to receive a response to the connection initialization request message, the response indicating a rejection of a media flow type of the communication connection in the first communication domain and comprising a predetermined indication portion, the predetermined indication portion indicating a re-routing request of the communication connection to a second communication domain; and a processor configured to process the received response. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51)
