A system and method for improving the communication security mainly includes: the information being interacted via the main link between the access layer apparatus and the user terminal apparatus in the normal work state, when a failure being detected in the main link between the access layer apparatus and the user terminal apparatus, a backup work link being established by said AMDF apparatus and the work link being switched to said backup link. It can realize the function of the backup of the user board port and the user board card so that the outage time of the system service is decreased and the security is increased. In addition, the configuration of the invention is clear and easily to be realized.

L'invention concerne un système et un procédé destinés à améliorer la sécurité de communication, qui incluent principalement : l'échange d'informations par l'intermédiaire de la liaison principale entre le dispositif de couche d'accès et le dispositif terminal d'utilisateur en état normal de travail, et, lorsqu'une défaillance est détectée dans la liaison principale entre le dispositif de couche d'accès et le dispositif terminal d'utilisateur, la mise en place d'une liaison de rechange par le dispositif AMDF et la commutation de la liaison principale vers ladite liaison de sauvegarde. Ils peuvent servir de port de carte d'utilisateur et de carte d'utilisateur de rechange de telle sorte que la durée d'interruption de service du système diminue et que la sécurité augmente. De plus, la configuration de l'invention est évidente et facile à réaliser.
