Abstract

La présente invention se rapporte à un procédé pour la détermination d'une priorité entre tranches de temps. Elle se rapporte également à un contrôleur de réseau radio (RNC). Le procédé selon l'invention comprend les étapes suivantes, consistant : à obtenir une puissance de porteuse transmise (TCP) de chaque tranche de temps sur la liaison descendante (DL) de chaque cellule voisine comportant des brouillages ; à exécuter une coordination des brouillages ; et à déterminer, sur la base de la TCP, la priorité entre les tranches de temps. La solution technique de la présente invention permet de refléter avec une grande précision un environnement comportant des brouillages de la tranche de temps durant laquelle une cellule cible doit être accédée, de telle sorte qu'un nouvel utilisateur puisse sélectionner et accéder à la tranche de temps la plus appropriée.
