Abstract

L’invention concerne un procédé de réalisation d’un guidage double dans un réseau avec contrôle et orientation séparés dans le champ de communication, comprenant les étapes suivantes : seul un ensemble de liaisons est configuré entre les MGC maîtres (en attente) et le MGW, où le MGW se connecte respectivement à toutes les liaisons des MGC maîtres et en attente ; il effectue une commutation entre le MGC maître et le MGC en attente en activant et désactivant directement les liens. Le procédé de réalisation du guidage double simplifie la configuration dudit guidage double et économise de l’espace mémoire sur les ensembles de liaisons.
