Abstract

La présente demande concerne un procédé de communication, un dispositif mobile, un dispositif électronique et un support de stockage lisible par ordinateur. Selon la présente demande, un premier dispositif électronique établit une connexion directe point à point avec un dispositif mobile et le premier dispositif électronique lit des données audio grâce au dispositif mobile. Après détection de la déconnexion de la connexion directe point à point entre le premier dispositif électronique et le dispositif mobile, le premier dispositif électronique reçoit un premier message servant à indiquer l'établissement, par le dispositif mobile, d'une connexion directe point à point avec un deuxième dispositif électronique. En réponse au premier message, le premier dispositif électronique envoie au deuxième dispositif électronique tout ou une partie du contenu non lu parmi les données audio. Selon la présente demande, après déconnexion d'une connexion entre deux dispositifs électroniques basée sur la technologie de connexion directe point à point, une connexion indirecte s'établit au moyen d'un troisième dispositif électronique, ce qui permet d'obtenir une continuité de service.
