Abstract

L'invention concerne un procédé pour compter le nombre d'utilisateurs de services de diffusion/multidiffusion multimédia (MBMS), ledit procédé affectant un identifiant d'état de service MBMS dans chaque contexte de service MBMS à chaque équipement utilisateur. Ce procédé consiste à fixer séparément, côté réseau, l'identifiant d'état de service MBMS correspondant à l'équipement utilisateur dans le contexte de service MBMS relatif à l'équipement utilisateur en tant que valeur active; et compter le nombre d'utilisateurs de chaque service MBMS en comptant le nombre de valeurs actives dans chaque contexte de service MBMS. Ce procédé de comptage du nombre d'équipements utilisateurs de MBMS, selon l'invention, peut compter exactement le nombre d'utilisateurs de chaque service MBMS utilisé par l'équipement utilisateur, évite la possession aberrante de ressources sans fil et permet ainsi d'exploiter au maximum les rares ressources d'interfaces hertziennes.
