Abstract

In the transfer of a connection between a packet-switched and a line-switched communications network, conversion of user data which are to be transmitted via the connection is controlled by a first gateway device disposed between the packet-switched and the line-switched communications network. The conversion is carried out depending on transfer information which is formed by a second gateway device located on the path of the connection and disposed between the line-switched and a further packet-switched communications network.

Claims

1. A method to control a conversion of user data which are to be transmitted via a connection between a first packet-switched communications network and a line-switched communications network provided by a first gateway device, comprising:

forming transfer information relating to a transfer of the user data between the line-switched communications network and a second packet-switched communications network by a second gateway device disposed between the line-switched communications network and the second packet-switched communications network;

forming conversion information relating to conversion characteristics of a conversion device disposed on a path of connection between the second gateway device and a connection destination; and

controlling the conversion of the user data by the first gateway device based on the transfer information and the conversion information.

2. A control system controlling a first gateway device and a second gateway device for conversion of user data to be transmitted via a connection between a first packet-switched communications network and a line-switched communications network, comprising:

transfer information means for forming transfer information relating to a transfer of the user data between the line-switched communication network and a second packet-switched communications network by the second gateway device disposed between the line-switched communications network and the second packet-switched communications network; and

means for forming conversion information relating to conversion characteristics of a conversion device disposed on a path of connection between the second gateway device and a connection destination; and

control means for controlling the conversion of the user data by the first gateway device based on the transfer information and the conversion information.
