Abstract

L'invention concerne un procédé et un appareil pour régler un débit de codage audio, utilisés pour résoudre le problème dans lequel la qualité audio d'un signal audio émis par un terminal ou une station de base ne peut pas être garantie tout au long d'un appel. Lors d'un processus de transmission de données audio, une première station de base règle, selon des valeurs d'un taux de perte de paquet associé à des données audio et un bloc de transport d'un terminal, un premier débit de codage du terminal en un second débit de codage, le premier débit de codage étant un débit de codage qui est actuellement utilisé par le terminal ; la première station de base envoie au terminal le second débit de codage ; et la première station de base reçoit, à partir du terminal, des données audio à l'aide du second débit de codage. La présente invention permet à une première station de base de régler, selon un taux de perte de paquet associé à des données audio et un bloc de transport d'un terminal, un débit de codage pour une transmission de données entre le terminal et la première station de base lors d'un appel, permettant ainsi de garantir la qualité audio d'une émission de signal audio entre le terminal et la première station de base.
