Abstract

The embodiments relate to, among other things, 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.

Claims

1. A method for signaling by means of signaling messages between a control unit and an interworking unit, comprising:

transmitting of a first H.248 ADD.req message from the control unit to the interworking unit,

transmitting of a first H.248 ADD.resp message from the interworking unit to the control unit,

transmitting of a second H.248 ADD.req message from the control unit to the interworking unit,

transmitting of a second H.248 ADD.resp message from the interworking unit to the control unit,

executing of an H.223 Multiplexing Level Negotiation by the interworking unit,

transmitting of a first H.248 MOD.req message from the control unit to the interworking unit,

transmitting of a first H.248 MOD.resp message from the interworking unit to the control unit,

transmitting of a second H.248 MOD.req message from the control unit to the interworking unit, and

transmitting of a second H.248 MOD.resp message from the interworking unit to the control unit.

3. The method as claimed in claim 1, wherein one or more of the following actions are executed by the interworking unit or by the control unit:

H.245;

Terminal Capability Set, Master Slave Termination,

H.245;

Terminal Capability Set Ack, Master Slave Termination Ack,

H.245;

Open Logical Channel

H.245;

Open Logical Channel Ack.

4. The method as claimed in claim 1, wherein the method is used for setting up a video telephony connection.

5. The method as claimed in claim 1, wherein the method is used for setting up a connection between a first terminal and a second terminal.

2. The method as claimed in 1, wherein a bearer connection is set up by the interworking unit.
