Abstract

Méthode pour réaliser une limitation de mobilité, qui repose sur un service d'un système de communication mobile, définissant différentes zones de limitation dans la zone de couverture du réseau mobile, configurant la relation correspondante entre chaque zone de limitation et les cellules qu'elle comprend dans MSC, et stockant la zone de limitation d'inscription de l'utilisateur et les droits aux services dans chaque zone de limitation dans HLR. Lorsque le terminal mobile s'inscrit, le VLR concerné envoie une requête d'inscription à HLR, HLTR extrait et retourne les informations des zones de limitation et des droits aux services en relation avec MSC où le terminal se situe actuellement à VLR et les y stocke. Lorsque le terminal mobile effectue des opérations de service, le BSC concerné envoie des messages de service transportant les informations sur la cellule où le terminal se situe à MSC. MSC détecte les zones de limitation que le terminal mobile inscrit de VLR et si les zones de limitation comprennent la cellule où se situe actuellement le terminal mobile et que le terminal mobile a droit aux services dans cette zone de limitation, alors le MSC autorise le service. L'invention peut appliquer la limitation de mobilité en fonction de la cellule sans effet négatif sur la charge réseau.
