Abstract

La présente invention concerne un procédé et un système de calcul de service de diffusion/multidiffusion multimédia (MBMS). Ledit procédé se déroule de la manière suivante : une MCE lance plusieurs processus de calcul de service de MBMS en parallèle ; un eNB exécute un processus de calcul de service de MBMS qui est lancé avec succès, et il collecte le retour d'informations d'un UE ; et ledit eNB remet un résultat de calcul de service de MBMS à ladite MCE selon le retour d'informations de l'UE qui a été collecté. La présente invention se rapporte également à un système de calcul de service de MBMS. Lorsque la MCE a lancé avec succès un processus de calcul de service de MBMS, un autre processus de calcul de service de MBMS peut être lancé sans attendre la fin du processus qui a été lancé avec succès, ce qui permet l'exécution de plusieurs processus de calcul de service de MBMS en parallèle, et la réalisation rapide du calcul de service de MBMS. En particulier, quand un opérateur a besoin de calculer plusieurs services de MBMS, le système peut terminer cette tâche en très peu de temps. Par le biais de l'évaluation de l'activation ou de la désactivation par un opérateur d'un service de MBMS, le taux d'utilisation des ressources s'améliore.
