Abstract
A network interface unit (IM-MGW) in which signaling data is separated from useful data by the values of received data. The signaling data is tunneled to a control unit (MGCF). Two different data transmission networks (CS, IMS) can thus be simply combined, in particular, for video telephony.
Claims13
A media gateway, comprising:
- a receiver that receives, from a first data transmission network, payload data and H.245 signaling data, the H.245 signaling data and payload data being transmitted within the same bearer connection;
- a signaling data transmission that sends the H.245 signaling data received at the receiver to a media gateway control unit, the H.245 signaling data being sent to the media gateway control unit unchanged and according to a control signaling method in accordance with the ITU-T H.248 protocol, the media gateway control unit controlling the media gateway and performing signaling interworking between the first data transmission network and a second data transmission network;
- a payload data transmit unit that sends the payload data received at the receiver into the second data transmission network;
- and
- a separation unit that separates the received H.245 signaling data and payload data from each other and forwards the H.245 signaling data to the signaling data transmit unit and forwards the payload data to the payload data transmit unit.

A media gateway control unit for controlling a media gateway and for performing signaling interworking between a first data transmission network and a second data transmission network, comprising:
- a receiver that receives signaling data in accordance with a first signaling method for the first data transmission network, the signaling data being H.245 messages, wherein the signaling data is received from the first data transmission network via a bearer connection setup between the media gateway and the first data transmission network and wherein the H.245 messages from the first data transmission network are forwarded by the media gateway in unchanged form to the media gateway control unit via the ITU-T H.248 protocol;
- a transmitter that transmits signaling data in accordance with a second signaling method for the second data transmission network;
- and
- a conversion unit which, starting from a signaling message in accordance with the first signaling method, creates a corresponding signaling message in accordance with the second signaling method.
