Le dispositif de gestion de position reçoit au moins les informations d'identification pour l'autre terminal qui ont été transmises par le terminal utilisateur appelant, et les informations d'identification qui identifient des terminaux utilisateurs et sont stockées dans le terminal utilisateur appelant. Ensuite, le dispositif de gestion de position détermine une destination de transfert pour l'appel pour qu'elle soit un terminal utilisateur dont la distance à l'autre terminal utilisateur est inférieure à un seuil, parmi les terminaux utilisateurs correspondant aux informations d'identification stockées dans le terminal utilisateur appelant, sur la base de l'association entre les informations de position et des informations d'identification d'une pluralité de terminaux utilisateurs, et des informations d'identification pour l'autre terminal et des informations d'identification stockées dans le terminal utilisateur appelant.
