Abstract

La présente demande se rapporte au domaine technique des communications. Sont divulgués un procédé et un appareil de résolution de collision de couleur de BSS, ainsi qu'un dispositif et un support de stockage. Le procédé est exécuté par un MLD AP, et le procédé consiste : lorsqu'une sélection de couleur de BSS est effectuée sur un premier AP dans un MLD d'AP, à sélectionner une couleur de BSS différente de couleurs de BSS d'autres AP, les autres AP étant des AP autres que le premier AP dans le MLD d'AP. Sur la base des solutions techniques présentées dans les modes de réalisation de la présente demande, un mauvais jugement de collision de couleur de BSS peut être évité.
