Abstract
The invention relates to a method of managing transmission errors between a base station and a transcoder, in a digital radiocommunications system for mobile stations, in which method the transcoder, in the presence of a transmission error, systematically inserts (29, 221, 228) an error message in a frame addressed to the base station without interrupting useful data transmission to the base station, and in which method the base station decides to interrupt data transmission to the transcoder (down direction) and generates an up-direction transmission interruption request when the transmission errors detected in the down direction and/or reported by an error message in the up direction satisfy predetermined conditions. In this way, all call-interruption decisions are centralized in the base station.
