Abstract

Est divulgué un procédé de détermination d'état de connexion d'une liaison radio. Le procédé comprend les étapes suivantes : lorsqu'un second temporisateur correspondant à une cellule de desserte est en cours de fonctionnement et qu'un équipement terminal déclenche un événement de mesure sur un objet de mesure, si un premier temporisateur correspondant à la cellule de desserte et à l'objet de mesure n'est pas démarré, l'équipement terminal démarre le premier temporisateur correspondant à la cellule de desserte et à l'objet de mesure ; ou, si un premier temporisateur correspondant à la cellule de desserte n'est pas démarré, l'équipement terminal démarre le premier temporisateur correspondant à la cellule de desserte ; et l'équipement terminal détermine l'état de connexion d'une liaison radio de la cellule de desserte sur la base du premier temporisateur, le second temporisateur étant démarré lorsque la liaison radio de la cellule de desserte est anormale. Sont également divulgués un autre procédé pour déterminer l'état de connexion d'une liaison radio, un dispositif de réseau et un support de stockage.
