Abstract

La présente invention se rapporte à un procédé de sélection de terminal cible. Le procédé selon l'invention comprend les étapes suivantes : un terminal mobile génère un déplacement relatif par rapport à un terminal cible visible, et il transmet et/ou il reçoit une onde acoustique ; des terminaux d'utilisateurs voisins, comprenant le terminal cible, reçoivent et/ou transmettent l'onde acoustique ; la fréquence de l'onde acoustique est enregistrée sur la base de l'onde acoustique qui a été reçue par le terminal mobile ou par les terminaux d'utilisateurs voisins ; un décalage en fréquence de l'onde acoustique provoqué par l'effet Doppler est calculé ; et le terminal d'utilisateur voisin dont le décalage en fréquence remplit une condition prédéfinie est utilisé en tant que le terminal cible. La présente invention se rapporte d'autre part à un terminal mobile qui comprend : un premier module de transmission ; un premier module de réception ; un premier module de traitement ; et un module de notification. La présente invention se rapporte par ailleurs à un système de sélection de terminal cible qui comprend : le terminal mobile ; et un dispositif distant. Le dispositif distant comprend : un second module de transmission ; un second module de réception ; un second module de traitement ; et un module de stockage. Le procédé, le système et le terminal mobile selon l'invention sont aptes à permettre la sélection d'un terminal cible à l'intérieur d'une plage visible.
