The advantage of the invention is that the edge node enables an active intervention into the signalling of the transmission of the multimedia data as packet data, i.e., this signalling need no longer ensue transparently to the mobile communication device. Another advantage is that, due to the integration of the control of the multimedia data transmission, the data streams can be adapted better to the radio resources and/or to the demands made of the mobile communication device.
