Abstract

L'invention concerne un système et un procédé d'accès faisant converger différentes technologies d'accès. Le procédé selon l'invention consiste à : en cas de nécessité d'accéder à un réseau faisant converger différentes technologies d'accès, transmettre d'un terminal de convergence à un commutateur d'accès de convergence un message de demande d'accès contenant une identification d'utilisateur et une identification de technologies d'accès par l'intermédiaire d'un réseau d'accès; et recevoir par l'intermédiaire du commutateur d'accès de convergence le message de demande d'accès et exécuter le processus d'autorisation par interaction avec les informations sur un serveur d'abonné résidentiel (HSS) contenant l'identification d'utilisateur et l'identification de technologies d'accès après avoir déterminé que les ressources correspondantes permettent l'accès du terminal de convergence, de façon à réaliser l'accès au réseau par convergence de différentes technologies d'accès. Grâce au système et au procédé selon la présente invention, le terminal peut accéder au réseau de communication mobile au moyen d'une pluralité de technologies d'accès, ce qui lui permet de faire converger et d'utiliser une pluralité de technologies d'accès pour fournir des services de communication, et d'améliorer l'expérience utilisateur.
