Par conséquent, dans la présente invention, le protocole RRC est compris dans un système de protocole sur lequel une fonction de relais est mise en œuvre, c'est à dire, le protocole RRC est compris dans un système de protocole côté relais d'un UE relais, ce qui permet de fournir une assistance technique pour la gestion de ressource radio ; lorsque la présente invention est appliquée, une personne qualifiée peut configurer une fonction RRC requise dans l'UE relais selon le protocole RRC régi par l'UE relais, de manière à réduire de façon appropriée le décalage de temps dans le processus de la commande de ressource radio.
