Abstract

Les modes de réalisation de la présente divulgation concernent un procédé et un appareil de traitement de défaillance, le procédé étant exécuté par un dispositif terminal. Le procédé consiste à : recevoir des informations de configuration, qui sont envoyées par un dispositif côté réseau, d'au moins une cellule ou d'un groupe de cellules; lire les informations de configuration; déterminer que la lecture des informations de configuration a échoué; et exécuter une procédure de traitement correspondant à la défaillance de lecture. Au moyen de la solution technique de la présente divulgation, lorsqu'il est déterminé que la lecture d'informations de configuration a échoué, un dispositif terminal peut exécuter une procédure de traitement correspondant à la défaillance de lecture. De cette manière, l'apparition d'une défaillance dans l'activation sélective d'une cellule ou d'un groupe de cellules peut être évitée, améliorant ainsi la fiabilité de communication.
