Abstract (en)

[origin: EP1841161A1] The method involves establishing a direct connection between communication devices using a direct connecting address, when communication devices (U2, C2, S2) assist a specified coding based on a coding information. A direct connection between the communication devices (U2, C2, S2) and a coding module and a gate way (GW1) is established using another address, when the communication devices (U2, C2, S2) do not assist the coding. User data are transmitted via a connection for the coding module and gate way and are encoded and transmitted to a communication device (S1).
