Le procédé pour découvrir un dispositif de commande de point d'accès sans fil comprend les opérations suivantes : lors de la détection d'un terminal non enregistré qui entre dans une région de couverture de réseau, un serveur de fonction de découverte et de sélection de réseau d'accès (ANDSF) acquiert des informations d'adresse concernant un dispositif de commande de point d'accès sans fil (AC) correspondant à des informations d'adresse concernant le terminal non enregistré; et envoie les informations d'adresse concernant l'AC au terminal non enregistré. La présente invention est principalement appliquée à un réseau d'accès sans fil.
