The navigation terminal information including whether or not to register the route guide indicating whether the registration is generated, stored in the navigation terminal information DB 321 and managed.

The route guide information management means 312 is a navigation guide operating as the route guide terminal 15 transmits route guide information (eg, location information, destination information, terminal identification code, etc.) transmitted along with a signal requesting registration of route guidance. Upon receipt, the terminal identification code included in the route guide information is checked to confirm whether the navigation terminal information DB is registered in the route guide service. The route guide information management means 312 waits for route guidance only for the route guide terminal 15 registered in the route guide service.

Furthermore, the route guide information management means 312 checks the received route guide information every predetermined time unit (for example, 10 seconds) and temporarily stores the route guide information in the temporary route guide information DB 322.

The route request information management means 313 receives route request information (eg, location information, destination information, terminal identification code, etc.) transmitted by the navigation terminal operating as the route request terminal 11 along with a signal for requesting route guidance. As a result, the path guide terminal extracting means 314 is called, and the path request information is temporarily stored in the temporary path request information DB 322.

The route guide terminal extracting means 314 is the route that matches or is similar to the route request information from the temporary route request information DB 322 and the temporary route guide information DB 322 according to a request of the route request information management means 313. Extract guide information. The route guide terminal extracting means 314 determines the similarity between the route request information and the route guide information, selects the route guide terminal 15 corresponding to the route guide information having the highest similarity, and generates route information. The identification code of the selected route guidance terminal 15 is transmitted to the route information generating means 315 together with the request signal.
In determining the degree of similarity, the location information and the destination information may be divided into, for example, a large classification (in city or province units in an administrative area), a middle classification (in city, group, or district units in an administrative area), and a small classification based on latitude and longitude. A similarity may be determined by designating a regional identification code composed of a town, a town, or the same unit in an administrative district, and determining whether the regional identification codes are similar to each other. Here, the similarity is determined to be the highest when the location information of the route guidance terminal 15 and the destination information and the route information of the route request terminal 11 are the same.

Although, in the preferred embodiment of the present invention, the route guidance terminal extracting means 314 illustrates the use of the similarity in selecting the route guidance terminal 15 to perform the route guidance from the extracted route guidance terminal 15. The invention is not limited to this.

Furthermore, as an alternative to selecting the route guidance terminal 15 using similarity, the user checks the route guidance terminals 15 extracted through the route request terminal 11 and the route guidance terminal 15 desired by the user. ) May be implemented to select directly.
