Abstract

Des modes de réalisation de la présente invention concernent un procédé et un appareil de rétroaction de service de groupe. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des informations de ressource de rétroaction envoyées par un dispositif sur le côté réseau, les informations de ressource de rétroaction étant utilisées pour identifier un intervalle de temps se produisant sur une ressource de rétroaction; et le dispositif terminal envoie des informations de rétroaction au dispositif sur le côté réseau selon l'intervalle de temps se produisant sur la ressource de rétroaction. Dans les modes de réalisation de la présente invention, un dispositif terminal reçoit des informations de ressources de rétroaction qui sont envoyées par un dispositif sur le côté réseau et qui sont utilisées pour identifier un intervalle de temps se produisant sur une ressource de rétroaction. De cette manière, après réception des données de service de groupe distribuées par le dispositif sur le côté réseau, un dispositif terminal dans un état de repos et un dispositif terminal dans un état connecté peuvent tous les deux envoyer des informations de rétroaction au dispositif sur le côté réseau selon un intervalle de temps se produisant sur une ressource de rétroaction. Cela permet d'améliorer la fiabilité de distribution de données de service de groupe.
