Abstract

Divers modes de réalisation de la présente invention divulguent un procédé pour faciliter l'interopérabilité de modèle entre différentes fonctions de réseau, telles qu'une fonction d'application (AF) et une fonction d'analyse de données de réseau (NWDAF) ou d'autres fonctions dans un réseau central de cinquième génération (5G) (5GC). Le processus d'établissement de liaison divulgué ici peut activer les fonctions de réseau pour déterminer s'il existe une interopérabilité de modèle et peut faciliter le partage de modèles, de poids et d'autres éléments de l'AF dans le 5GC ou inversement. Les données de modèle peuvent être fournies à une fonction logique d'entraînement de modèle (MTLF) ou à une fonction logique analytique (AnLF) qui est actionnée par une NWDAF pour un apprentissage fédéré (FL) ou un apprentissage par transfert.
