Abstract

L'invention porte sur un procédé de détection d'échec de circuit de jonction de plan utilisateur, qui comprend les opérations suivantes : un module de processeur de flux multimédia local se détecte lui-même sur la jonction d'un module de processeur de flux multimédia correspondant sur le même plan utilisateur (31) ; lorsque le module de processeur de flux multimédia local détecte lui-même qu'il est inatteignable pour au moins une jonction du module de processeur de flux multimédia correspondant, il détermine qu'un échec de circuit s'est produit par rapport à ladite jonction de plan utilisateur. L'invention porte aussi sur un procédé d'établissement de rapport d'échec de circuit de jonction de plan utilisateur, comprenant les opérations suivantes : détecter s'il y a ou non un échec de circuit de jonction de plan utilisateur ; si le résultat de détection est qu'un échec de circuit de jonction de plan utilisateur s'est produit, rapporter l'information au module de commande de communication (34). L'invention porte également sur un module de processeur de flux multimédia, sur un dispositif d'accès à un réseau et sur un dispositif d'accès au module.
