Abstract
From a mobile communication device, road information about either a preliminarily registered point or an arbitrary point on a route from a present position to a destination is transmitted to and received in a network navigation center via a cellular phone base station and a general telephone network. Based on that road information, the network navigation center retrieves traffic information about the registered point or the arbitrary point on the route, and then transmits the retrieved traffic information to the mobile communication device via the general telephone network and the cellular phone base station. The traffic information includes traffic congestion area data about the registered point or the arbitrary point on the route, which is displayed on a display in the mobile communication device wherein the user is informed of future traffic information like traffic congestion.
