Abstract

The present invention proposes a transmission method for transmitting data in a telecommunication network (NW), said telecommunication network comprising at least one access network (RAN) adapted to transmit data to/from at least one terminal device (MS) and a core network (CN, MSC, GW/TC), which are connected to each other via a first interface (Iu), wherein said data are exchanged via said first interface (Iu) using a real-time transfer protocol (RTP). Preferably, said real-time transfer protocol complies with ITU-T H.225 and ITU-T H.323 Recommendations. Consequently, transmission resources available on said first interface can be effectively and economically used, since the RTP protocol conforming to ITU-T H.323 Recommendation is adapted to handle discontinuous transmission. Moreover, interoperability of the radio telecommunication network with an Internet protocol based network can be improved, since the gateway functionality can significantly be reduced due to data being transmitted between the telecommunication network and the Internet protocol based network being in the same data format, so that hardly any transcoding is required. The invention also proposes a corresponding telecommunication network.
