Abstract

La présente invention concerne le domaine technique des réseaux. Un mode de réalisation de la présente invention concerne un nœud, ainsi qu'un procédé et un système de multiplexage de ressources. Le procédé comprend une étape au cours de laquelle un premier nœud de commande central d'un premier réseau coexistant paramètre un domaine temporel de détection dans le domaine temporel éligible et demande à des premiers nœuds communs nécessitant un multiplexage dans le premier réseau coexistant d'envoyer successivement des signaux ISP d'un premier système coexistant dans le domaine temporel de détection, de sorte qu'un nœud spécifié dans un second système coexistant détecte dans le domaine temporel de détection si les signaux ISP sont reçus, ainsi qu'une étape consistant à déterminer, sur la base du résumé des résultats de détection, si les premiers nœuds communs peuvent multiplexer des ressources dans le second système coexistant. Dans la présente invention, les premiers nœuds communs nécessitant un multiplexage de ressources envoient successivement des signaux ISP dans le domaine temporel de détection, et le nœud spécifié dans le second système coexistant détecte si les signaux ISP sont reçus, ce qui détermine si les premiers nœuds communs peuvent multiplexer des ressources dans le second système coexistant, de sorte qu'un réseau dans un système coexistant peut multiplexer des ressources dans d'autres systèmes coexistants.
