Abstract

La présente invention concerne un dispositif de côté réseau et un procédé d'ordonnancement, le procédé d'ordonnancement comprenant les étapes consistant à : acquérir, par un dispositif de côté réseau, un volume de données d'antémémoire d'un équipement d'utilisateur; calculer, par le dispositif de côté réseau, un niveau de priorité d'ordonnancement de l'équipement d'utilisateur en fonction du volume de données d'antémémoire; et ordonnancer, par le dispositif de côté réseau, une ressource allouée pour l'équipement d'utilisateur en fonction du niveau de priorité d'ordonnancement. Le procédé et l'appareil de la présente invention permettent de résoudre le problème technique de l'art antérieur, faisant que la qualité de l'expérience d'utilisation est influencée par l'imprécision d'un schéma d'ordonnancement servant à déterminer un niveau de priorité d'ordonnancement de ressources en fonction d'une vitesse d'émission de canal.
