La présente invention concerne une technique d'accès double à internet dans laquelle un équipement de locaux d'abonné prend en charge un accès double à internet , qui effectue une commande de commutation sur un trajet d'accès externe entre un réseau de communication mobile et un réseau à large bande (internet), en réponse à une situation de communication, de manière à détecter, en temps réel, une défaillance dans l'accès à internet lorsque la qualité d'accès à internet est mauvaise ou l'accès à un réseau de communication internet filaire est difficile en raison d'un incendie de tunnel de câble et similaire et à maintenir de manière stable la qualité d'accès à internet par commutation de trajet d'accès correspondant à la défaillance. Selon la présente invention, l'accès à internet peut être maintenu de manière stable par l'intermédiaire d'un accès double à un réseau de communication mobile et à internet, et, en particulier, même lorsque l'accès à internet câblé ralentit ou est coupé, ou lorsque l'accès au réseau de communication internet filaire est difficile en raison d'un incendie de tunnel de câble et similaire, l'équipement de locaux d'abonnés peut assurer une connectivité de communication à internet pour des utilisateurs en intérieur.
