Les étapes du procédé consistent en ce qu'un serveur de souscription dynamique initie l'établissement de support entre le serveur de souscription dynamique et un équipement utilisateur (UE) à inscrire selon un message de requête de contrat dynamique envoyé par un élément de réseau de gestion mobile ; que le serveur de souscription dynamique et l'élément de réseau de gestion mobile appartiennent à un premier réseau et l'UE à inscrire appartient à un second réseau ; que des informations de compte de l'UE à inscrire sont acquises par le biais du support ; et que les informations de compte sont envoyées à un serveur d'abonné domestique (HSS) du premier réseau, de sorte que le HSS établit un compte temporaire dans le premier réseau pour l'UE à inscrire en fonction des informations de compte. Les modes de réalisation de la présente invention concernent en outre le serveur de souscription dynamique et l'élément de réseau de gestion mobile. Une liaison dynamique entre l'UE et un fournisseur de service de communication peut être réalisée, et l'utilisateur peut sélectionner le fournisseur de service de communication librement sur la base des situations actuelles, par exemple la couverture réseau et la facturation.
