Abstract:
1. A method for controlling the operation of a transcoder of a mobile communication system, in which system the transcoder is connected to a base station by a telecommunication connection, the method comprising: the transcoder receiving, from the base station, frames containing speech parameters, which the transcoder decodes into speech signals to be transmitted to a mobile services switching centre, the transcoder receiving, from the mobile services switching centre, speech signals which the transcoder encodes into speech parameters to be transmitted to the base station in frames, the base station monitoring a need to adjust timing of the frames received from the transcoder and indicating a transmission moment timing adjustment need to the transcoder by transmitting information indicating the adjustment need to the transcoder, the transcoder adjusting a transmission moment in response to the adjustment need indicated by the base station, defining a limit for a longest transmission delay allowed between the transcoder and the base station, and when the transmission delay exceeds the limit transmitting to the base station, predetermined control information, which controls the base station to stop the indication of the adjustment need to the transcoder such that the transcoder stops adjustment of the transmission moment of the frames to be transmitted to the base station.
