Abstract

L'invention concerne un procédé de traitement d'une politique de transmission multimédia, et un dispositif associé. Le procédé consiste à : recevoir un message de demande de traitement de politique de transmission multimédia, le message de demande de traitement de politique de transmission multimédia contenant des informations de politique de transmission multimédia, les informations de politique de transmission multimédia étant utilisées pour déterminer une politique de transmission multimédia devant être traitée, et la politique de transmission multimédia comprenant une opération de transmission multimédia et une condition de déclenchement correspondant à l'opération de transmission multimédia ; déterminer un mode de traitement de politique de transmission multimédia d'après le message de demande de traitement de politique de transmission multimédia ; et traiter la politique de transmission multimédia selon le mode de traitement de politique de transmission multimédia. Le processus de traitement d'une politique de transmission multimédia permet d'exécuter une opération de transmission multimédia d'une politique de transmission multimédia cible lorsqu'une condition de déclenchement d'opération pour la politique de transmission multimédia cible est satisfaite et, partant, de renforcer la flexibilité d'une commande de transmission multimédia.
