1. A method for transmitting control information between a line-switching and a packet-switching communications network, comprising the steps of:
- converting user data signaling messages into signaling packets that are used between the line-switching network containing control information and the packet-switching communications network containing control information;
setting up a signaling connection for transmitting signaling packets, which form connection-independent control information which relates to at least one service feature in the line-switching communications network, in the packet-switching network in order to use the at least one service feature of the line-switching communications network in the packet-switching communications network by means of the control information, independently of the connection.

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.

12. A control unit for conversion of user data signaling messages used between a line-switching communications network containing control information, to signaling packets used in a packet-switching communications network containing control information, the control unit is arranged at the transmitter or receiver end of a signaling connection which is set up in the packet-switching communications network for transmitting signaling packets, and having a module for integration and extraction of connection-independent control information, which relates to at least one service feature in the line-switching communications network, into and out of the signaling packets to be transmitted.
