Abstract

L'invention porte sur un procédé d'accès d'utilisateur et sur un équipement de passerelle dans un système WiMAX, qui s'applique dans un système d'interopérabilité mondiale pour l'accès hyperfréquence (WiMAX) comprenant un réseau de service d'accès (ASN) et un réseau de service de connexion (CSN). Le réseau ASN est connecté à au moins un réseau CSN. Le procédé comprend les opérations suivantes : le réseau ASN reçoit une requête d'accès du terminal et obtient des informations de domaine; le réseau ASN détermine le réseau CSN auquel le terminal accède conformément aux informations de domaine du terminal. L'invention porte également sur un équipement de passerelle qui utilise le procédé. Par utilisation du procédé, l'accès d'utilisateur peut être commandé de façon sélective ou politique et les exigences de ressources réseau des utilisateurs qui ont déjà accédé au réseau peuvent être satisfaites et une qualité de service plus élevée est obtenue.
