Speech is transmitted between a base station (BTS) and a TRAU by converting a speech signal into a parameter group which is inserted in a traffic frame which is transmitted as a packet comprising a header and a payload. In accordance with the invention, the payload is formed of the contents of several traffic frames until the payload is essentially full, and a packet is sent to the destination via the transmission network. At the destination the traffic frames are separated from the payload of the received packets and they are passed to a speech decoder. The packing of packets full can be started about a second after the beginning of the connection and after pauses, in which case the ending of a pause is transmitted to the listener as fast as possible.

Des signaux vocaux sont transmis entre une station de base (BTS) et une unité transcodeur et d'adaptation de vitesse (TRAU) par conversion d'un signal vocal en un groupe paramétrique qui est introduit dans un bloc de trafic transmis sous forme d'un paquet comprenant un en-tête et une charge utile. Selon l'invention, la charge utile est constituée par le contenu de plusieurs blocs de trafic jusqu'à ce qu'elle soit essentiellement pleine, et un paquet est transmis à la destination via le réseau de transmission. Une fois parvenus à destination, les blocs de trafic sont séparés de la charge utile des paquets reçus et envoyés à un décodeur de signaux vocaux. Le remplissage total des paquets peut être démarré environ une seconde après le début de la connexion et après les pauses, dans lequel cas la fin d'une pause est transmise à la personne à l'écoute aussi vite que possible.
