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.
