Abstract

Suite à une première requête d’appel reçue, un serveur SIP émet une deuxième requête d’appel pour appeler des membres de conversation en groupe correspondant à la première requête d’appel et transmet des informations de réception de requête d’appel signifiant que le serveur SIP a reçu la première requête d’appel avant de transmettre la deuxième requête d’appel aux membres de conversation en groupe. En fonction des informations de réception de requête d’appel reçues, un serveur SMS inclut des informations dans le message de démarrage pour démarrer une application implémentant une conversation en groupe et les transmet aux membres de la conversation en groupe.
