Abstract

La présente divulgation concerne un procédé d'établissement de connexion, un premier nœud, un second nœud et un troisième nœud. Le procédé comprend les étapes suivantes : premièrement, un troisième nœud envoie des troisièmes informations à un premier nœud, puis le premier nœud envoie des premières informations à un second nœud, et le second nœud reçoit les premières informations envoyées par le premier nœud. Ainsi, le problème de la manière de sélectionner un élément de réseau central approprié pour qu'un équipement utilisateur (UE) effectue une communication est résolu dans une certaine mesure.
