Abstract

La présente invention appartient au domaine des communications radio. L'invention concerne un procédé et un dispositif de commande d'accès à un réseau de raccordement sans fil, et un support de stockage. Le procédé comprend les étapes consistant à : recevoir une demande d'accès d'un second nœud sans fil via un canal de commande de trajet de raccordement du premier nœud sans fil, et guider le second nœud sans fil via le canal de commande de trajet de raccordement du premier nœud sans fil, pour accéder à un canal de service de raccordement sans fil du premier nœud sans fil, le premier nœud sans fil étant prévu sur un côté réseau de raccordement, et le premier nœud sans fil et le second nœud sans fil prenant en charge une liaison de raccordement. L'invention améliore la flexibilité de la construction et de l'accès à un trajet de raccordement ainsi que la performance globale d'un réseau de raccordement. Elle fournit en outre un canal de raccordement simple et robuste, qui peut être ajouté ou supprimé en toute liberté.
