Abstract

L'invention concerne un procédé et un système pour une régulation de niveau d'utilisateur IMS en fonction des données d'abonnement. Le procédé comprend les étapes suivantes : lors de la réception d'une demande d'enregistrement ou d'une demande de session d'un utilisateur, un dispositif de régulation de services de niveau d'utilisateur obtient les informations d'utilisateur correspondant à l'identifiant d'utilisateur, et effectue respectivement la régulation de QoS, la régulation du nombre d'utilisateurs d'enregistrement ou la régulation du nombre de sessions concurrentes du niveau d'utilisateur selon les informations d'utilisateur obtenues. Les informations d'utilisateur sont stockées dans une base de données d'utilisateurs (UDB) du système lorsqu'un compte est ouvert par l'utilisateur. Par l'utilisation du mode de réalisation de l'invention, le nombre d'utilisateurs d'enregistrement ou le nombre de sessions concurrentes sera régulé. Lorsque le système NASS n'est pas déployé dans le réseau IMS, la régulation de services précis d'utilisateur de l'utilisateur peut être réalisée selon les informations de données d'abonnement d'ouverture de compte de l'utilisateur.
