Abstract
In a mobile speech communication system including a base station having a data connection to a mobile services switching center through a transcoder unit, where the data connection includes a circuit-switched data transmission connection between the base station and transcoder unit to exchange speech parameters transmitted as TRAU frames, the data connection also being partly composed of a packet-switched data transmission connection to improve the data transmission connection, a converter is arranged on the data transmission connection between the base station and the transcoder unit for converting a TRAU frame received from the circuit-switched data transmission connection into a packet to be transmitted over the packet-switched connection, wherein the conversion includes a removal of bits included in the TRAU frame which are not needed on the packet-switched connection. The converter also for converting a packet received from the packet-switched connection into a TRAU frame to be transmitted over the circuit-switched connection, wherein the conversion includes at least the addition of synchronization bits to the TRAU frame.
