Abstract

La présente divulgation concerne un procédé et un appareil de traitement de défaillance de connexion et un support de stockage lisible. Le procédé consiste à : en réponse à une défaillance de connexion se produisant au niveau d'un UE de relais, enregistrer des informations d'une liaison relais. Dans le procédé selon la présente divulgation, lorsqu'une défaillance de connexion se produit au niveau d'un UE de relais, l'UE de relais ou un UE distant peut enregistrer des informations d'une liaison relais, et les envoyer à un dispositif de réseau à une occasion appropriée. De cette manière, le dispositif de réseau peut recevoir non seulement des informations de défaillance d'une interface Uu, mais également les informations de la liaison relais, de sorte que le dispositif de réseau puisse optimiser une liaison latérale en fonction des informations de la liaison relais ou exécuter un autre traitement correspondant approprié.
