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.
