Abstract

La présente invention décrit un procédé permettant de traiter un encombrement de réseau, un dispositif de réseau et un système de réseau. Le présent procédé comprend les étapes suivantes : un dispositif de réseau d'accès reçoit un message d'indication incluant un mode de contrôle d'accès transmis par un élément réseau de gestion de la mobilité, ledit message d'indication étant envoyé lorsque l'élément réseau de gestion de la mobilité a acquis un encombrement de réseau ; le dispositif de réseau d'accès rejette ou retarde l'accès du terminal selon ledit message d'indication. La présente invention peut réduire l'état d'encombrement de réseau et éviter une détérioration supplémentaire de l'encombrement de réseau.
