Abstract

La présente invention permet un transfert de données fiable à une temporisation prédéterminée dans un dispositif de communication et supprime la consommation d'énergie. Une unité de radiocommunication peut être utilisée dans un premier mode de radiocommunication pour émettre un signal de balise par diffusion aux environs de cette dernière, un deuxième mode de radiocommunication pour recevoir un signal de balise à partir des environs de cette dernière, et un troisième mode de radiocommunication pour réaliser une communication de monodiffusion avec un autre dispositif de communication. En réponse à une requête de transfert qui demande le transfert de données à un dispositif de communication de destination de transfert, l'unité de traitement amène l'unité de radiocommunication à réaliser une transition du premier mode de radiocommunication au deuxième mode de radiocommunication et à fonctionner. À l'aide d'informations d'identification d'un dispositif de communication de source d'émission de signal de balise, qui sont incluses dans le signal de balise provenant des environs reçu dans le deuxième mode de radiocommunication, une unité de transfert amène l'unité de radiocommunication à fonctionner dans le troisième mode de radiocommunication de telle sorte que les données sont transférées par une communication de monodiffusion au dispositif de communication de source d'émission.
