Abstract

Un método de transmisión para tramas de inactividad vocal codificados en la fuente en un sistema de radiocomuni cación TDMA que tiene un extremo transmisor y uno receptor (RX;TX), que funcionan con un régimen R de transmisión de tramas, y que tiene un canal de tráfico vocal en el que la señal de la fuente es transmitida en al menos dos modos, de los cuales un modo se aplica durante períodos inactividad vocal, funcionando las tramas de inactividad vocal a un régimen r de tramas de inactividad vocal que es menor que R, comprendiendo el método las operaciones de: usar un régimen de transmisión de tramas igual o mayor que r para la transmisión de las tramas (FIRST SID, SID UPDATE)(primer descriptor de silencio y de actualización del descriptor de silencio) de inactividad vocal protegidas de errores de canal; enviar repetidamente las tramas de inactividad vocal codificados (SID UPDATE) durante los períodos de inactividad vocal en caso de que el régimen de transmisión de tramas sea igual a r; y reducir la potencia de transmisión en una magnitud tal que la potencia de transmisión sea, todavía, suficientemente alta para que el extremo de recepción descodifique las tramas de inactividad dentro de algún criterio de calidad predeterminada.
