Abstract

La présente invention concerne un procédé et un appareil d'acquisition d'identifiant d'utilisateur. Le procédé d'acquisition d'identifiant d'utilisateur comprend les étapes suivantes : réception d'un message d'acquisition d'identifiant d'utilisateur envoyé par un dispositif de réseau ; et selon le message d'acquisition d'identifiant d'utilisateur, fourniture d'un identifiant d'utilisateur cible au dispositif de réseau. Par conséquent, la présente invention permet à un dispositif de réseau de s'abonner à des informations de niveau d'utilisateur côté réseau ou d'importer des informations de niveau d'utilisateur côté service dans un réseau au moyen d'un identifiant d'utilisateur acquis à partir d'une AMF, de sorte qu'une garantie déterministe pour un service de niveau d'utilisateur soit réalisée.
