Abstract

Ce procédé, ce système et cet appareil de mise en oeuvre de la notification de services de diffusion/multidiffusion accompagnant le système de services diffusion/multidiffusion (BM) à une seule porteuse consistent à: a) envoyer l'information d'indication du service BM sur la porteuse BM et la porteuse non BM; et b) recevoir l'information spécifique du service BM de modification de porteuse. Le procédé permet à l'équipement UE de recevoir l'information sur la modification de services sur n'importe quelle porteuse de UE, de telle sorte à assurer que UE reçoive le service BM correctement sur la porteuse BM.
