Abstract (en)
[origin: WO2007045526A1] The invention relates to a e and method for setting up a telecommunication connection, in particular a video telecommunication connection, which after being established, is carried out by means of a line-bound telecommunications network (CS) and an IP multimedia subsystem telecommunications network (IMS), wherein a media gateway control function device (MGCF) of said IP multimedia subsystem telecommunications network (IMS) comprises at least one Internet multimedia-media gateway device (IM-MGW). The inventive method consists in exposing an H.223 multiplex level usable for a telecommunication connection to an H.223 protocol negotiation, in carrying out an H.245 protocol negotiation for setting up the H.223 protocol negotiation connection for a telecommunication connection and in informing the media gateway control function device (MGCF) when the H.223 logic channels are open by means of a H.245 signalling, thereby enabling the Internet multimedia-media gateway device (IM-MGW) of the IP multimedia subsystem telecommunications network (IS) to carry out at least one of said three steps.
