Title (EN) SYSTEM AND METHOD FOR INTER-DOMAIN MOBILITY MANAGEMENT
(FR) SYSTEME ET PROCEDE DE GESTION DE LA MOBILITE INTER-DOMAINE
Abstract:
(EN) The present invention relates to a method and apparatus for inter-domain (10,20) mobility management for a telephony network which includes gatekeepers GK (14, 16, 24, 26) and border elements BE (12, 22). The present invention also relates generally to the H.323 standard for transmitting audio and video data streams, and more particularly to extending the H.323 standard to support mobile H.323 entities (28) in a multimedia communication system with services over packet-based networks.
(FR) La présente invention concerne un procédé et un appareil de gestion de mobilité inter-domaine (10, 20) pour un réseau téléphonique comportant des portiers GK (14, 16, 24, 26) et des éléments frontaliers BE (12, 22). L'invention se rapporte généralement à la norme H.323 utilisée pour transmettre des trains de données audio et vidéo et plus particulièrement, à l'extension de la norme H.323 (28) pour la prise en charge de la mobilité dans un système de communications multimédias assurant des services sur des réseaux par paquets.
