Processing of multimedia calls (Fig. 5) in a packet-based network builds on existing call model processing by maintaining the use of the basic call state models (542) to control the overall two-party call and the use of connection views (550) to associate multiple two-party calls and provide access to advanced supplementary services. Through the use of multimedia view processor (552), the system separates multimedia connection handling from call handling. The basic call models (542) are extended to support new messages and enhanced messages for creating, modifying, and deleting multimedia view objects and communicating modifications to the media streams between call state model processors (524) and protocol specific processors (522).

L'invention concerne le traitement d'appels multimédia dans un réseau à commutation par paquets. Ce traitement met à profit un traitement de modèles d'appel existant en continuant à utiliser des modèles d'état d'appel de base (542) afin de commander l'appel général à deux abonnés et à utiliser des visualisations de connexion (550) pour associer plusieurs appels à deux abonnés et permettre d'accéder aux services complémentaires avancés. Grâce à un processeur de visualisations multimédia (552), le système sépare la gestion des connexions multimédia de la gestion des appels. Les modèles d'appel de base (542) sont élargis de façon qu'ils supportent de nouveaux messages et des messages améliorés afin de créer, de modifier et d'effacer des objets de visualisation multimédia et de transmettre ces modifications aux flux multimédia entre les processeurs de modèle d'état d'appel (524) et des processeurs spécifiques de protocole (522).
