Abstract

Sont divulgués dans la présente demande un procédé et un appareil d'accès ou de transfert, une AMF et un support de stockage. Le procédé comprend les étapes suivantes : lorsqu'un terminal commute d'un accès à partir d'une AMF source à un accès à partir d'une AMF cible, l'AMF source envoie des premières informations de fonction de réseau ; et l'AMF source reçoit des premières informations de réponse de l'AMF cible, les premières informations de réponse indiquant si l'AMF cible peut être desservie par une première fonction de réseau indiquée dans les premières informations de fonction de réseau ou si l'AMF cible peut communiquer avec la première fonction de réseau.
