Abstract

La présente invention concerne un procédé de partage d'un réseau mobile. Le procédé consiste, lorsqu'un UE (Equipement Utilisateur) se trouvant dans un état inactif passe d'un réseau LTE (Evolution à long terme) à un réseau à partage GERAN (Réseau d'accès radio GSM/EDGE), à acquérir un ancien ID de réseau PLMN (Réseau mobile terrestre public) ou une ancienne RAI (Identité d'accès radio) d'un domaine PS (à Commutation de paquets) lorsque l'UE se trouve dans le réseau LTE; choisir un réseau PLMN correspondant à l'ancien ID de réseau PLMN ou à l'ancienne RAI pour qu'il joue le rôle de réseau PLMN du domaine PS du réseau GERAN de l'UE, le réseau PLMN du domaine PS étant identique au réseau PLMN d'un domaine CS (à Commutation de circuits) sélectionné par l'UE dans le réseau LTE. Le procédé de partage de réseau mobile proposé dans les modes de réalisation de la présente invention permet d'éviter le problème selon lequel l'UE ne peut pas acquérir un service normal en raison du fait qu'un réseau PLMN d'un domaine PS d'un abonné à un service est différent d'un réseau PLMN d'un domaine CS.
