Abstract

L'invention concerne un procédé et un dispositif de découverte de fonction de réseau (NF). Le procédé comprend les étapes suivantes : une NRF reçoit une première demande de découverte, la première demande de découverte comprenant des informations de niveau correspondant à une NF cible ; la NRF envoie une deuxième demande de découverte à une base de données centrale selon les informations de niveau ; la base de données centrale détermine des informations de la NF cible, les informations de la NF comprenant un des éléments parmi des informations d'identité de la NF, le niveau déterminé de la NF cible, et un niveau correspondant aux informations de niveau, et envoie les informations de la NF cible à la NRF ; la NRF envoie une réponse de découverte, la réponse de découverte comprenant les informations de la NF cible. Dans le procédé, après la réception d'une demande de découverte, la NRF obtient des informations d'une NF auprès d'une base de données centrale. Ainsi, le déploiement multicouche de NRF n'est plus nécessaire, de sorte qu'un demandeur n'a plus besoin d'effectuer un processus de sélection de NRF complexe lors de l'envoi d'une demande de découverte de NF.
