Abstract

L'invention concerne un procédé pour découvrir l'accès du système de commande d'appel, qui comprend les étapes suivantes : un serveur d'authentification, d'autorisation et de comptabilisation alloue l'adresse du point d'accès du système de commande d'appel pour les terminaux, et envoie l'adresse du point d'accès du système de commande d'appel aux terminaux. Un autre procédé pour découvrir l'accès du système de commande d'appel et deux systèmes pour la découverte de l'accès du système de commande d'appel sont également proposés. Par l'allocation par le serveur d'authentification, d'autorisation et de comptabilisation ou HA de l'adresse du point d'accès du système de commande d'appel pour les terminaux et l'envoi de l'adresse du point d'accès du système de commande d'appel aux terminaux, les terminaux peuvent également obtenir l'adresse du point d'accès du système de commande d'appel sans interagir avec le serveur DHCP dans le procédé DHCP, pour obtenir que les terminaux obtiennent l'adresse du point d'accès d'appel puis découvre l'accès d'appel de manière plus flexible et pour faciliter la gestion centralisée du point d'accès du système de commande d'appel en raison de la gestion unifiée et de l'allocation de l'adresse du point d'accès du système de commande d'appel par un serveur AAA ou HA.
