Abstract

L'invention fournit un procédé de mise à jour pour des configurations de canaux multi-commande MBS. Le procédé de mise à jour consiste à : recevoir un bloc d'informations système d'un canal BCCH pour acquérir des informations d'une pluralité de canaux de commande MBS ; surveiller sélectivement, parmi la pluralité de canaux de commande MBS, une notification de changement d'un canal de commande MBS, qui programme un service MBS requis ; après la réception de la notification de changement, recevoir des informations de configuration mises à jour du canal de commande MBS dans le cycle de changement suivant du canal de commande MBS ; et lire les informations de configuration mises à jour du canal de commande MBS pour recevoir le service MBS requis. Un UE surveille sélectivement, en fonction d'un service MBS requis, une notification de changement d'un canal de commande MBS qui programme le service MBS, de manière à recevoir des informations de configuration requises par l'UE, ce qui empêche l'UE de surveiller la notification de changement de façon continue et répétée et de recevoir des informations de configuration inutiles, de sorte que les coûts de ressources de l'UE pour surveiller la notification de changement sont réduits, et l'UE est plus économe en énergie.
