Abstract

La présente invention concerne le domaine technique des communications, et en particulier un procédé et un appareil de transmission de données, qui sont utilisés pour résoudre le problème d'une réduction de la qualité de service de transmission causée par le fait que la transmission continue du service ne peut pas être garantie après que le service d'un utilisateur a été réorienté d'une technologie d'accès radio (RAT) vers une autre RAT. Le procédé de transmission de données décrit comporte les étapes consistant à: faire recevoir par un UE des données de liaison descendante émises par un dispositif d'accès radio de réseau non cellulaire, et déterminer un type de données des données de liaison descendante reçues d'après des premières informations d'indication de convergence servant à indiquer le type de données des données de liaison descendante; et après qu'il a été déterminé que le type de données des données de liaison descendante est celui de données de réseau cellulaire, faire traiter par l'UE les données de liaison descendante au moyen d'un protocole de réseau cellulaire. En raison du fait qu'un UE peut traiter des données de liaison descendante au moyen d'un protocole de réseau cellulaire après avoir reçu les données de liaison descendante qui sont réexpédiées par un dispositif d'accès radio de réseau non cellulaire et proviennent d'un dispositif d'accès radio de réseau cellulaire, des RAT différentes sont fusionnées, la transmission continue d'un service est garantie et la qualité de transmission de services est améliorée.
