Abstract

L'invention concerne un procédé pour une planification d'utilisateur dans un mode d'activation/désactivation de motif. Le procédé consiste : à diviser des utilisateurs sous des stations de base de cellule en groupes ; à configurer des facteurs de tendance d'activation/désactivation correspondants pour des utilisateurs de différents groupes qui sont obtenus par division ; et à réaliser une planification juste et proportionnelle sur les utilisateurs selon les facteurs de tendance d'activation/désactivation. L'invention concerne également une station de base pour une planification d'utilisateur dans un mode d'activation/désactivation de motif, et un support de stockage informatique.
