Abstract

L'invention concerne un procédé et un système d'appel de capacité de réseau central, le procédé comprenant les étapes suivantes : une fonction d'exposition à un réseau (NEF) ou une plateforme de libre accès à une capacité reçoit une demande d'appel de capacité de réseau central en provenance d'un côté d'application ; en fonction de la demande d'appel de capacité de réseau central, la NEF ou la plateforme de libre accès à une capacité utilise une commande logique spécifique pour sélectionner un élément de réseau central 5G ou un élément de réseau central 4G qui nécessite un routage ; la NEF ou la plateforme de libre accès à une capacité envoie la demande d'appel de capacité de réseau central à l'élément de réseau central 5G ou à l'élément de réseau central 4G sélectionné ; et la NEF ou la plateforme de libre accès à une capacité renvoie au côté d'application une réponse d'appel de capacité de réseau central à partir de l'élément de réseau central 5G ou de l'élément de réseau central 4G. Dans la présente invention, une interface ascendante ouverte à une capacité d'élément de réseau et une interface d'accès convergent d'élément de réseau central 4G/ 5G fournies par la NEF ou la plateforme de libre accès à une capacité sont utilisées pour fournir une interopérabilité d'utilisateur 4G/ 5G ouverte unifiée pour une application tierce et une application possédée qui utilisent des capacités de réseau central.
