A private IP address is converted into a public IP address in a communications network without adapting a client software. The conversion of the private IP addresses into the public IP addresses is carried out via a network address translation. The private IP address of each terminal included in a payload of the IP data packet is convertible into a corresponding public IP address and, if necessary, vice-versa.

Method and device for translating internet protocol addresses inside a communications network

According to the invention, a power characteristic information concerning a power characteristic profile of a target terminal is transmitted to a base terminal, before transferring signaling of a connection set up from a base terminal to a target terminal. As a result of the connection set up signaling, a power characteristic request is transferred based on the power characteristic information.

Method for controlling power characteristics in packet-oriented communication networks

The method is essentially carried out by a gateway device, which is logically divided up into a gateway controller and one or, if required, more user data gateways. Quality of service signaling is evaluated by the gateway controller and, depending thereon, quality of service information is transferred to a user data gateway. Specific quality of service properties of connection segments coming into and/or going out from the user data gateway are evaluated by the user data gateway and, depending thereon, a quality of service setting is carried out according to the transferred quality of service information.

Method for supporting quality of service features in heterogeneous communications networks

Method of transmission of data between at least two communication devices which are connected together over a data network. The communication devices are respectively connected to a coding device and the sent data are source-and channel-coded by a coding method respectively furnished within the coding devices. The data are converted within a converting device connected to the data network.
