Abstract

Les modes de réalisation de la présente demande concernent un procédé et un appareil de positionnement. Dans la présente demande, un centre de localisation mobile de passerelle (GMLC) peut demander, au moyen d'un identifiant d'une zone de localisation, l'acquisition d'un identifiant d'un équipement utilisateur dans la zone de localisation et d'un résultat de positionnement de l'équipement utilisateur à partir d'un élément de réseau à fonction de gestion d'accès et de mobilité (AMF). C'est-à-dire que le GMLC peut rapporter le résultat de positionnement d'un utilisateur dans la zone de localisation sur la base de l'identifiant de la zone de localisation, c'est-à-dire que le GMLC peut réaliser le positionnement d'un équipement utilisateur dans n'importe quel lieu ou région où des utilisateurs ne sont pas fixés, de telle sorte que la qualité de service pour les utilisateurs est améliorée, l'interaction de signalisation peut également être réduite et l'expérience de service est améliorée.
