Abstract: It is proposed a method for establishing a IP-telecommunications between two participants with a specific control of data stream from that multimedia IP-telecommunications while maintaining the IP-telecommunications between the first and the second participant terminal originally targeted. This is achieved by setting up a connection for the transmission of packets comprising multimedia data from the IP-telecommunications between a terminal from the first participant and a terminal from the second participant both connected to the IP-network while using a sniffer to analyze the header of the data packets from that IP-telecommunications received via the IP-network by the first or second participant. It is provided on that first or second participant terminal of a possibility to initiate a redirection of the analyzed packets corresponding to a specific data stream defined in the header of the respective packets towards a further terminal interconnected with that first or second participant terminal.

Abstract: In a system for transmitting digital signals between two equipment units of a mobile radio network in accordance with a digital transmission protocol, the equipment units are interconnected by an analog link. The system includes digital-analog converters for transmitting the signals on the analog link and analog-digital converters for reception of the signals by one of the equipment units in digital form.
