ABSTRACT:
A method is provided for transmitting control information between a line-switching and a packet-switching communications network. A signaling connection is set up in a packet-switching network in order to transmit signaling packets which form connection-independent control information which relates to at least one service feature in a line-switching communications network so that at least one service feature of the line-switching communications network may be used in the packet-switching communications network by means of the control information independently of the connection.
