Abstract

L'invention concerne un procédé de commutation en continu pour un dispositif sans fil entre des réseaux longues distances sans fil (WWAN) et des réseaux locaux sans fil (WLAN). Selon ce procédé, les réseaux WWAN et WLAN disponibles sont automatiquement détectés, un des réseaux disponibles est sélectionné pour être utilisé par le dispositif sans fil, qui est alors connecté au réseau sélectionné. Ce procédé consiste également à maintenir la connectabilité (112) du réseau par la surveillance de la connexion et, si l'on constate que la connexion a été perdue (114), à sélectionner un autre réseau disponible et à connecter le dispositif sans fils à cet autre réseau (120). En outre, le procédé communique l'information concernant la disponibilité des réseaux et l'état d'une connexion à un utilisateur de dispositif sans fil, cet utilisateur pouvant alors commuter manuellement la connexion du dispositif sans fil du réseau disponible sélectionné automatiquement un autre réseau disponible. La présente invention porte également sur l'exécution par un dispositif sans fil dudit procédé.
