Abstract

L'invention concerne un format de message vocal en communication à ressources partagées et un procédé de transmission associé. Ce procédé permettrait de sauvegarder la largeur de bande de réseau entre le système de station de base et le serveur de distribution à ressources partagées. Le procédé consiste notamment: (a) après établissement d'un appel à ressources partagées, en ce que l'utilisateur parlant envoie des trames vocales au système de la station de base; (b) en ce que le système de la station de base encapsule toutes les N trames vocales dans un message vocal et envoie le message à un serveur de distribution à ressources partagées; (c) en ce que le serveur de distribution à ressources partagées transmet le message vocal de réception au système de station de base auquel appartiennent tous les utilisateurs du groupe de l'utilisateur parlant; (d) le système de station de base auquel appartiennent tous les utilisateurs du groupe démonte le message vocal reçu en N trames vocales et transmet les trames aux utilisateurs du groupe écoutant dans l'ordre d'origine. Le message vocal comporte un en-tête de transmission, un en-tête de paquet de données et la partie données vocales. L'en-tête de transmission contient des informations de format de transmission. L'en-tête de paquet de données contient les informations relatives à l'utilisateur et aux données vocales. La partie données vocales contient de multiples trames vocales disposées selon un ordre de priorité.
