Abstract:
A method is provided for signaling a change from a first service to a second service during a call between a terminal device and a further terminal device over at least one communication network. When a change from the first service to the second service takes place during a call between the terminal device and the further terminal device, a network unit of the communication network, via which the terminal device is currently communicating to at least one further network unit, signals whether the change was initiated by the terminal device or by a network unit of the communication network.
