Abstract

L'invention concerne un procédé et un dispositif de communication sans fil, ledit procédé consistant : à envoyer, par un SMF et à un premier dispositif, des premières informations d'au moins un flux QoS après division d'un SDF, les premières informations permettant au premier dispositif de déterminer la technologie d'accès utilisée par ledit flux QoS. Sur la base de la solution technique précitée, en divisant le SDF en au moins un flux QoS, des données peuvent être reçues et/ou envoyées au moyen de la technologie d'accès utilisée par ledit flux QoS, ce qui permet d'éviter de changer de technologie d'accès, utilisée pour recevoir et/ou envoyer les données, pour le flux QoS, et permettant ainsi d'améliorer l'efficacité de transmission des données.
