Abstract

La présente divulgation concerne un procédé et un appareil de transmission pour un service de multidiffusion. Le procédé est appliqué à un terminal et consiste à : lorsqu'il est dans un état RRC non connecté, exécuter une opération définie lors de la réception des données de service d'un service de multidiffusion, l'opération définie comprenant la mesure de la RSRP d'une cellule de desserte et/ou la mesure du BLER du service de multidiffusion qui est reçu et/ou la mesure de la durée de réception du service de multidiffusion lorsqu'il est dans l'état RRC non connecté et/ou la réalisation d'une resélection de cellule ; et à condition que le résultat de l'opération remplisse une condition prédéfinie, déclencher l'entrée dans état RRC connecté à partir de l'état RRC non connecté, et continuer à recevoir les données du service de multidiffusion. Les informations permettant de déclencher la mise à jour d'un état RRC par le terminal sont configurées de façon à ce qu'un UE puisse commuter de l'état RRC non connecté à l'état RRC connecté et continuer à recevoir le service de multidiffusion, ce qui garantit la fiabilité et la continuité de la réception du service de multidiffusion par le terminal.
