Abstract

La présente invention concerne un procédé consistant à découvrir, par un dispositif client dans un réseau sans fil, une disponibilité d'un nouveau dispositif à établir une connexion au Nuage (par exemple, Internet) par l'intermédiaire du réseau sans fil, et à déterminer un ensemble de services de base de point d'accès ou à créer un ensemble de services de base indépendants comme point d'entrée pour permettre au nouveau dispositif de se joindre au réseau sans fil sur une liaison sans fil. De plus, le procédé consiste à établir une session de communication sécurisée sur la liaison sans fil, et à envoyer, du dispositif client au nouveau dispositif, des informations comprenant des justificatifs d'identité de réseau sans fil et des informations d'enregistrement nécessaires pour établir une connexion du nouveau dispositif au Nuage par l'intermédiaire du réseau sans fil.
