Abstract

L'invention porte sur un procédé permettant à une station de base de notifier à un équipement utilisateur (UE) de lire un canal de commande de multidiffusion (MCCH), sur la station de base, sur un procédé permettant à l'équipement utilisateur de lire le MCCH, et sur l'équipement utilisateur ; ils sont utilisés pour assurer que l'équipement utilisateur reçoit correctement des informations de notification, ce par quoi l'équipement utilisateur peut lire le MCCH et acquérir le service de diffusion/multidiffusion multimédia (MBMS) à temps, la robustesse de l'équipement utilisateur recevant le MBMS est améliorée et la probabilité pour que l'équipement utilisateur perde le MBMS est réduite. Le procédé décrit et qui permet à l'équipement utilisateur de lire le MCCH comprend les opérations suivantes : la station de base détermine qu'un démarrage de nouvelle session MBMS existe actuellement ; la station de base envoie à l'équipement utilisateur des informations de notification pour notifier à l'équipement utilisateur de lire des informations MCCH plusieurs fois dans une même période de modification de MCCH ; l'équipement utilisateur surveille les informations de notification envoyées par la station de base plusieurs fois dans une même période de modification de MCCH, et lit les informations MCCH conformément aux informations de notification surveillées.
