Abstract

La présente invention se rapporte au domaine de la communication sans fil. La présente invention concerne un procédé et un dispositif d'affectation de ressource de support, le procédé consistant à : recevoir l'identifiant et une priorité d'affectation et de retenue (ARP) d'un équipement utilisateur (UE) de groupe non de grappe transmis par une entité de gestion de mobilité (MME) ; sélectionner un groupe de grappe, et acquérir l'ARP correspondant au groupe de grappe ; et si l'ARP de l'UE de groupe non de grappe est supérieure à l'ARP correspondant au groupe de grappe, alors libérer les ressources de support occupées par tous les UE dans le groupe de grappe, et affecter les ressources de support pour l'UE de groupe non de grappe. Le dispositif comprend un module de réception, un premier module d'acquisition et un module d'affectation. Dans la présente invention, si l'ARP de l'UE de groupe non de grappe est supérieure à l'ARP correspondant au groupe de grappe, alors les ressources de support de tous les UE dans le groupe de grappe sont réquisitionnées, permettant ainsi d'éviter l'impact sur une planification unifiée de l'UE de groupe de grappe par un serveur de grappe en raison de la réquisition de la ressource de support d'un UE dans le groupe de grappe.
