Abstract

L’invention concerne un procédé et un système de contrôle d’accès pour un accès IP (protocole Internet) local. Les informations de capacité d’accès LIPA (accès IP local) à Internet et/ou les informations de capacité d’accès LIPA au réseau domestique sont notifiées à un terminal utilisateur par la diffusion d’un message par un élément de réseau sans fil/une passerelle de station de base domestique ; le terminal utilisateur sélectionne l’élément de réseau sans fil/la station de base domestique afin d’accéder au LIPA selon les informations de capacité d’accès LIPA à Internet et/ou les informations de capacité d’accès LIPA au réseau domestique obtenues. Étant donné que les informations de capacité d’accès LIPA à Internet et/ou les informations de capacité d’accès LIPA au réseau domestique sont notifiées au terminal utilisateur par l’élément de réseau sans fil/la passerelle de station de base domestique, il est garanti que le terminal utilisateur peut sélectionner l’élément de réseau sans fil qui possède une capacité d’accès à Internet LIPA ou la passerelle de station de base domestique qui possède une capacité d’accès LIPA au réseau domestique. Par conséquent, toute refonte inutile pour accéder au LIPA est évitée, la réussite de la fonction d’accès IP local est garantie, et le taux de réussite de l’accès utilisateur est amélioré.
