Abstract

L'invention concerne un procédé, un appareil et un système d'attribution de ressources. Le procédé comprend les étapes suivantes : configurer une ressource correspondante pour deux connexions ou plus établies par un équipement utilisateur et un côté réseau, les connexions comportant une connexion principale et une connexion auxiliaire ou les connexions comprenant la connexion auxiliaire, et différentes connexions étant différenciées au moyen de différents identifiants de connexion ; et notifier à l'équipement utilisateur la ressource configurée. De plus, une ressource peut également être configurée pour différentes cellules dans une même connexion, et des configurations de ressources de différentes cellules sont différenciées au moyen de différents identifiants de cellule. De cette manière, différentes connexions sont différenciées au moyen d'identifiants de connexion, et des configurations de ressources de différentes cellules dans une même connexion sont différenciées au moyen d'identifiants de cellule ; en conséquence, le problème de la confusion d'objets de configuration de ressources peut être résolu.
