Abstract

La présente invention se rapporte à un procédé de négociation de route IP. L'invention se rapporte d'autre part à un système et à un dispositif correspondants. La présente invention appartient au domaine technique des communications. Le procédé de négociation de route IP selon la présente invention comprend les étapes suivantes : une première passerelle multimédia sélectionne, sur la base d'une adresse IP définie pour elle, une adresse IP définie pour une seconde passerelle multimédia ; la première passerelle multimédia sélectionne d'autre part des données d'état relatives à la qualité de service (QoS) d'une route IP de la première passerelle multimédia, une route IP ayant une QoS optimale entre la première passerelle multimédia et la seconde passerelle multimédia. Le procédé décrit dans le mode de réalisation de la présente invention permet à la première passerelle multimédia de transmettre des informations relatives à une route IP optimale à la seconde passerelle multimédia. On peut ainsi être certain que la route IP sélectionnée pourra garantir la qualité des communications.
