A mobile first terminal () has a call in progress with a second terminal () under a first communications service via a base station () of the access network of a first subsystem. A condition for transferring the call to a base station () of the radio access network of a second subsystem is detected in a radio network controller () of the first subsystem. A core network switch () which is linked to the radio network controller () of the first subsystem is informed of said detection of a call transfer condition. If the second subsystem cannot process the call under the first communications service, a service change is requested so that said call can continue under the second communications service.

Method for controlling communication service in a telecommunication and communicator associated therewith

Handover is performed from a first radio network controller to a second radio network controller, where the first and second radio network controllers are associated with corresponding first and second control nodes. An access gateway node receives at least one command that is transmitted by one of the first and second control nodes associated with the respective first and second radio network controllers, where the access gateway node contains data functions of the first and second control nodes. In response to the at least one command, the access gateway node bicasts traffic data from the data functions for receipt by the first and second radio network controllers.
