Abstract
The present invention relates to a method of changing a telecommunication channel in a mobile communication system for a given mobile station, which mobile station has a connection in progress, and the connection is provided with a channel on a radio connection between the mobile station and base station system and a telecommunication channel between the base station system and a mobile services switching center. In order to facilitate the changing of the telecommunication channel the method includes putting a new telecommunication channel between the mobile services switching center and the base station system, indicated by the handover message into use for the connection, and connecting the channel used to the new telecommunication channel in such a way that the radio channel remains unchanged irrespective of the change of the telecommunication channel.
