Abstract

L'invention porte sur un procédé, un dispositif et un système de prétraitement de transition d'état. Le procédé de prétraitement de transition d'état comprend les opérations suivantes : une station de base diffuse des informations pré-transition (301); un UE terminal reçoit les informations pré-transition et mesure un signal reçu en provenance d'une région adjacente afin d'obtenir un résultat de mesure (302); l'UE détermine si une condition de rapport préétablie est satisfaite en fonction du résultat de mesure (303); et lorsqu'il est déterminé que la condition de rapport préétablie est satisfaite, l'UE rapporte le résultat de mesure à la station de base (304).
