Abstract

La présente invention concerne un procédé et un appareil de détermination d'un état d'achèvement d'une reprise après défaillance de faisceau de cellule. Le procédé comprend les étapes consistant à : déterminer de lancer un processus de reprise après défaillance de faisceau (BFR) dans une cellule secondaire ; et déclencher un élément de commande (CE) de contrôle d'accès au support (MAC), le MAC CE étant utilisé dans la cellule secondaire pour exécuter le processus BFR. Le MAC CE est transmis. Une fois le MAC CE transmis, un premier temporisateur est lancé. Sur la base du premier temporisateur, un état d'achèvement de BFR relatif à la cellule secondaire est déterminé. Lors d'une détermination d'un lancement d'un processus BFR dans une cellule secondaire, un MAC CE est déclenché. Le MAC CE est transmis. Le processus BFR est exécuté sur la base du MAC CE. Puis un premier temporisateur est lancé. Sur la base du premier temporisateur, un état d'achèvement de BFR relatif à la cellule secondaire est déterminé. De ce fait, il est confirmé si la BFR de la cellule secondaire a réussi, ce qui règle le problème technique de ne pouvoir déterminer si un processus BFR a été achevé avec succès.
