Abstract

La présente invention concerne un dispositif et un procédé d'indication d'informations. Le procédé comprend les étapes suivantes : un premier dispositif de terminal détermine des premières informations d'indication sur la base d'un état de liaison actuel entre le premier dispositif de terminal et un dispositif de réseau, l'état de liaison actuel étant une défaillance de reconfiguration de liaison, une commutation de liaison défaillante, une commutation en cours, une défaillance de liaison sans fil, ou un rétablissement de connexion de commande de ressource sans fil ayant échoué ; et le premier dispositif de terminal transmet les premières informations d'indication à un second dispositif de terminal, les premières informations d'indication étant utilisées pour notifier au second dispositif de terminal l'état de liaison actuel entre le premier dispositif de terminal et le dispositif de réseau, le premier dispositif terminal étant un dispositif capable d'aider le second terminal à communiquer avec le dispositif de réseau. Le second dispositif de terminal détermine une stratégie de chape sur la base de l'état de liaison actuel entre le premier terminal et le dispositif de réseau, le retard de communication du second dispositif de terminal est réduit, et l'efficacité de communication est augmentée.
