Abstract

L'invention concerne un procédé de coopération inter-stations de base, une station de base et un système d'exploitation et de gestion (OAM), le procédé comprenant les étapes suivantes : une première station de base acquiert des secondes informations d'interaction de capacité indiquant la capacité de coopération d'une seconde station de base (310) ; et la première station de base établit une relation de coopération avec la seconde station de base en fonction des capacités de coopération des première et seconde stations de base (320), la capacité de coopération représentant la capacité de la coopération entre les stations de base supportée. Le mode de réalisation de la présente invention acquiert, par l'intermédiaire d'une première station de base, les secondes informations d'interaction de capacité indiquant la capacité de coopération d'une seconde station de base, de telle sorte que la première station de base peut établir une relation de coopération avec la seconde station de base en fonction des capacités de coopération des première et seconde stations de base, réalisant ainsi la coopération entre les stations de base.
