Abstract

La présente invention se rapporte à un procédé et à un appareil adaptés pour exécuter le transfert d'un appel aléatoire. Le procédé selon l'invention comprend les étapes suivantes : un serveur sélectionne un premier terminal client et un second terminal client qui peuvent correspondre, parmi la pluralité de terminaux client qui transmettent des demandes d'appel aléatoire ; le serveur transfère ensuite la demande d'appel aléatoire du premier terminal client, au second terminal client. La solution technique décrite dans la présente invention est ainsi apte : à simplifier la procédure de signalisation ; à accélérer la vitesse de connexion ; et à satisfaire l'exigence privée relative à l'appel aléatoire.
