Abstract

L'invention concerne un procédé de transmission de données par l'intermédiaire de canaux d'interface radio, entre une première station (UE) et une seconde station (B) côté réseau d'un système de communication à transmission par paquets (UMTS). Selon ledit procédé, des données d'un seul service correspondant à différents critères d'attribution sont transmis par l'intermédiaire de l'interface radio (V). Pour une transmission plus efficace des données, il est proposé que les données soient également transmises côté réseau dans des canaux ou liaisons qui diffèrent de façon correspondante.
