Abstract

La présente invention, qui appartient au domaine technique des communications sans fil, concerne un procédé et un appareil de communication capables de réduire des coûts de construction. Dans le procédé, un premier élément de réseau à fonction d'exposition de réseau peut recevoir un message de demande de localisation pour demander des informations de localisation d'un dispositif de terminal. Le premier élément de réseau à fonction d'exposition de réseau peut envoyer un premier message de demande à un second élément de réseau à fonction d'exposition de réseau d'un second réseau. Le premier élément de réseau à fonction d'exposition de réseau peut également recevoir les informations de localisation du dispositif de terminal envoyées par le second élément de réseau à fonction d'exposition de réseau. Le premier élément de réseau à fonction d'exposition de réseau peut envoyer une réponse à la demande de localisation transportant les informations de localisation. Sur la base de la solution susmentionnée, aucun élément de réseau lié à un service de positionnement ne doit être déployé dans un premier réseau du fait que, lorsqu'un service de positionnement est requis, un premier message de demande peut être envoyé à un second réseau pour demander au second réseau de fournir un service de positionnement. Le premier réseau peut recevoir des informations de position envoyées par le second réseau, ce qui réalise le positionnement d'un dispositif de terminal. L'invention peut réduire des coûts de construction, de fonctionnement et de maintenance, et réduire la complexité de fonctionnement et de maintenance.
