Abstract

La présente invention se rapporte à un procédé de reporting adapté pour garantir la continuité de réception d'un service de transmission de données multimédias en diffusion/multidiffusion (MBMS, Multimedia Broadcast Multicast Service). Le procédé selon l'invention comprend l'étape suivante : un UE rapporte des données relatives au statut de réception d'un MBMS, à un réseau, au moyen d'un message de rapport de mesure. La présente invention se rapporte d'autre part à un UE adapté pour garantir la continuité de réception d'un MBMS. La présente invention permet de rapporter un statut de réception au moyen d'un message de rapport de mesure. Quand le réseau exécute un transfert intercellulaire, le réseau se réfère au statut de réception du MBMS dans le but de garantir la continuité de réception du MBMS par l'UE.
