Abstract

Un mode de réalisation de la présente invention concerne un procédé et un dispositif pour annuler l'autorisation de service dans un service basé sur la proximité (ProSe), le procédé consistant : à transmettre un message de changement de service ProSe pour le serveur d'abonné résidentiel (HSS) du réseau mobile terrestre public de rattachement (HPLMN) d'un équipement utilisateur (UE), le message de changement de service ProSe comprenant un identifiant de service ProSe, un identifiant d'UE et une période de temps prédéterminée et une instruction au HSS de ne pas permettre à l'UE de réaliser le service ProSe pendant la période de temps prédéterminée ; à recevoir un message de réponse de changement de service ProSe transportant l'identifiant de l'UE transmis par le HSS ; et à annuler l'autorisation du service ProSe de l'UE pendant la période de temps prédéterminée. Le procédé et le dispositif pour annuler l'autorisation de service dans un ProSe, selon le mode de réalisation de la présente invention, permet de réduire la complexité de traitement et le surdébit de signalisation dans le ProSe.
