Abstract

La présente invention concerne un procédé destiné au transfert de service entre passerelles dans le réseau de service, comprenant les étapes suivantes : après réception par le réseau de service du message de demande d’accès, ledit réseau de service détermine s’il doit traiter lui-même le message de demande d’accès, si le réseau de service détermine qu’il doit le traiter lui-même, le réseau de service traite le message de demande d’accès lui-même, et termine le flux ; dans le cas contraire, le réseau de service transmet le message de demande d’accès à une autre passerelle d’objets. La présente invention concerne une passerelle de service destinée à la mise en œuvre de la transmission de service entre les passerelles. En activant l’intercommunication de ressources en utilisant l’état entre chaque passerelle correspondante dans le réseau de service d’accès WiMAX, et en utilisant la transmission opportune de service pour ajuster correctement la charge de chaque passerelle correspondante, la présente invention équilibre bien la charge de manière à assurer le fonctionnement normal du système et à améliorer l’efficacité du système.
