Title
(EN) METHOD FOR PROVIDING A MOBILE STATION WITH SEAMLESS COVERAGE IN A 2G/3G COMMUNICATION NETWORK AND A WLAN
(FR) PROCEDE POUR REALISER UNE STATION MOBILE A COUVERTURE CONTINUE DANS UN RESEAU DE COMMUNICATION 2G/3G ET UN RESEAU LOCAL RADIO
Abstract
(EN) A method is described herein that enables data traffic to be routed seamlessly to a mobile station which is located in a Second Generation/Third Generation (2G/3G) network and a Wireless Local Area Network (WLAN). In one embodiment of the present invention, the mobile station (MS) receives a signal (e.g., System Information (SI) signal) from a base station system (BSS) which informs the MS that it should check for the presence of one or more WLANs. The MS then scans for beacons that are emitted from one or more WLANs. Once, the MS receives a beacon from a WLAN it can access that WLAN. To access the WLAN, the MS could send a signal to the BSS informing the BSS and possibly a gateway GPRS service node (GGSN) that it has received a beacon from the WLAN. Then, the MS can receive a signal from the BSS (or GGSN) which contains information (e.g., password, encrypted key) that enables the MS to access the WLAN. Once, the MS is attached to the WLAN, then the GGSN or another common node can route data to the MS via the WLAN instead of via the BSS.
(FR) La présente invention concerne un procédé permettant l'acheminement du trafic de données sans rupture de charge jusqu'à une station mobile d'un réseau 2G/3G et dans un réseau local radio (WLAN). Dans un mode de réalisation, la station mobile (MS) reçoit un signal, par exemple un signal 'SI' pour 'Information Système' en provenance d'un système de stations de bases qui informe la station mobile qu'elle doit vérifier l'existence d'au moins un réseau local radio. La station mobile fait une recherche systématique des balises émises par un ou plusieurs WLAN. Pour l'accès aux WLAN, la station MS peut envoyer un signal au système de stations de base, et éventuellement à un noeud de service GPRS de la passerelle, les informant de la réception d'une balise du WLAN. Ensuite, la station mobile peut recevoir du système de stations de base, ou du GGSN, un signal contenant de l'information telle qu'un mot de passe ou une clé cryptée, permettant à la station mobile d'accéder au WLAN. Une fois que la station mobile est rattachée au WLAN, le noeud GGSN, ou un autre noeud commun, peut acheminer des données à la station mobile via le WLAN au lieu de passer par le système de stations de base.
