VERFAHREN ZUM WEITERLEITEN VON SIGNALISIERUNGSDATEN IN EINER NETZÜBERGANGSEINHEIT UND IN EINER STEUEREINHEIT

摘要

The method involves transmitting user data between two data transmission networks (CS, IMS), in which two signaling process are signaled, respectively, in a network interface unit (IM-MGW). The data is received from one network through a data transmission connection. Signaling data and user data are separated in the interface unit using values of received data, and the received signaling data is transmitted from the interface unit in unmodified form to a control unit (MGCF). The user data is transmitted from the former network into the latter network in the interface unit. Independent claims are also included for the following: (1) a network interface unit for executing a method of transmitting signaling data (2) a control unit for executing a method of transmitting signaling data.
