Abstract

La présente invention concerne un procédé permettant de transmettre des données de trafic aux utilisateurs d'un réseau local radio (WLAN). On définit des notificateurs de trafic prévus pour la transmission aux terminaux utilisateur du réseau local radio des notifications d'accès au trafic. Avant que certains notificateurs de trafic ne transmettent les données au terminal utilisateur du réseau local radio sans se connecter à l'unité de service de trafic considérée, celle-ci transmet au notificateur de trafic une notification d'accès au trafic ou des données de trafic. Une fois que le notificateur de trafic a reçu ces informations, il fait des interrogations pour connaître l'adresse de l'unité de connexion d'accès utilisateur qui se connecte au terminal utilisateur du réseau local radio, puis transmet à cette unité la notification d'accès au trafic sur la base de cette adresse. Une fois qu'elle a reçu la notification d'accès au trafic, l'unité de connexion d'accès utilisateur transmet au terminal utilisateur du réseau local radio la notification d'accès au trafic en utilisant les connexions existant entre l'unité de connexion d'accès utilisateur et le terminal utilisateur du réseau local radio. Le procédé de la présente invention convient à la transmission au terminal utilisateur de la notification d'accès au trafic quand le terminal utilisateur n'établit pas de connexions directes avec le trafic desservi par l'accès.
