Abstract

L'invention concerne un procédé utilisé pour réaliser une interaction vocale, comprenant les étapes suivantes: le serveur de ressources multimédias MRS reçoit un message d'invitation émis par un terminal utilisateur, ledit message d'invitation transportant les informations SDP du terminal utilisateur; ledit MRS rétropopage un message sonore vers le terminal utilisateur, lequel transporte des informations MRS SDP; ledit terminal utilisateur et le MRS établissent un canal multimédias RTP à protocole de transmission en temps réel en fonction des informations SDP interactives des deux côtés, ce qui permet l'interaction vocale à travers un canal multimédias RTP. L'invention concerne également un système pour réaliser une interaction vocale. Le procédé et le système susmentionnés peuvent établir un canal multimédias RTP en avance, de manière à éviter la collecte de frais de service par le fournisseur de services réseau pour le processus interactif vocal entre le terminal utilisateur et le RMS, tout en réduisant les coûts de fonctionnement du fournisseur de services.
