Abstract

Selon l'invention, à chaque fois qu'un serveur d'assistance (720) reçoit l'information de mesure réelle à partir de l'un quelconque parmi une pluralité de véhicules en déplacement (MVk) (k = 0, …), des moyens de génération (723) actualisent une information d'environnement de communication comprenant une information d'état de communication associée à une information de date et d'heure sur chacune d'une pluralité de zones en fonction de l'information de mesure réelle afin de la mémoriser dans des moyens de mémorisation (721). Lorsqu'on spécifie une destination dans un terminal mobile (710), des moyens de commande (711A) transmettent une demande afin d'acquérir l'information d'environnement de communication au serveur d'assistance (720). En réponse à la demande d'acquisition, des moyens de notification (724) renvoient l'information d'environnement de communication correspondant à la demande d'acquisition aux moyens de commande (711A). Les moyens de commande (711A) ayant reçu le retour de l'information d'environnement de communication ordonnent à des moyens de présentation d'informations (712) de présenter une information concernant l'environnement de communication à partir de la position actuelle d'une voiture (CR0) jusqu'à la destination. Ceci permet d'assister la détermination d'un itinéraire de déplacement afin d'assurer le taux de réception de données de communication dans un dispositif de communication se déplaçant avec un véhicule mobile.
