Abstract

La présente invention concerne un procédé de contrôle de session comprenant: suite à l'établissement d'une session entre une extrémité de transmission et une extrémité de réception, l'extrémité de réception envoie un message de demande d'enregistrement à l'extrémité de transmission, et l'extrémité de réception enregistre l'information transmise depuis l'extrémité de transmission lorsqu'elle reçoit le message d'enregistrement autorisé renvoyé par l'extrémité de transmission. L'invention concerne également un terminal comportant un module de communication de type CS, un module de communication IMS et un module d'enregistrement, et comporte également un module de contrôle de demande d'enregistrement relié au module d'enregistrement. L'invention concerne également un terminal comportant un module de communication CS et un module de communication de type IMS, et également un module de contrôle d'enregistrement interdit relié au module de communication de type IMS. L'invention concerne en outre un système de session. L'invention peut permettre le contrôle de l'action d'enregistrement de l'extrémité de réception par l'extrémité de transmission de la session multimédia, pour ensuite protéger efficacement les droits d'auteur et le caractère privé de l'utilisateur de l'extrémité de transmission.
