Abstract

L'invention concerne un procédé et un système servant à découvrir des affaires multimédias en mode continu, qui comprennent les étapes suivantes : le côté du réseau du sous-système multimédia IP (IMS) crée les informations choisissant les affaires et les informations découvrant les affaires, puis envoie les informations découvrant les affaires à l'UE en fonction des informations de l'équipement utilisateur (UE) ayant accès au réseau IMS ; l'UE obtient les informations choisissant les affaires créées par le côté du réseau IMS en fonction des informations découvrant les affaires. Sur la base de la technique IMS, l'unité découvrant les affaires peut envoyer les informations découvrant les affaires à l'UE automatiquement en fonction des informations de l'UE ayant accès au réseau IMS, et l'UE obtient les informations choisissant les affaires en fonction des informations découvrant les affaires.
