Abstract

L'invention concerne un procédé et un système qui permet de réduire à un minimum des essais de qualité de service (MDT) d'un service de diffusion/diffusion groupée multimédia (MBMS), une station de base et un équipement utilisateur (UE). Le procédé comprend les étapes suivantes : une station de base obtient des informations indiquant qu'un UE est en train de recevoir un MBMS, sélectionne un UE qui doit effectuer une MDT en fonction des informations d'indication, d'une capacité MDT de l'UE et d'informations d'accord de l'utilisateur de l'UE, et envoie des informations de configuration MDT comprenant des informations de région à l'UE ; un eNB reçoit un résultat MDT rapporté pour la MDT effectuée par l'UE conformément aux informations de configuration MDT.
