Route guiding method in a navigation system using a wireless network
First Claim
1. A route guiding method in a navigation system comprising an information center including a map database, a navigation terminal located within a moveable object including a mobile terminal, wirelessly connected to a wireless network, and an ITS (Intelligent Transportation System) terminal with a GPS (Global Positioning System) device for detecting a current location of the moveable object, the wireless network for connecting the information center and the navigation terminal wirelessly, the method comprising the steps of:
- (1) receiving route guidance data by which the moveable object is guided to a destination via a plurality of node points on an optimum route at the navigation terminal from the information center;
(2) determining whether a user has requested a preview to receive comprehensive optimum route information;
(3) determining whether the user has requested the preview in text or in image if the preview has been requested;
(4) displaying the comprehensive route information in text upon request for the preview in text; and
(5) generating preview information about each node point on the optimum route based on the route guidance data and displaying the preview information in image upon request for the preview in image.

Abstract
A route guidance method in a navigation system using a wireless network, wherein a navigation terminal receives route guidance data by which a moveable object is guided to a destination via a plurality of node points in an optimum route from an information center. The navigation terminal determines whether a user has requested a preview of an optimum route. If the preview has been requested, the navigation terminal determines whether preview information is to be provided in text or in image. Upon request for the preview in text, the navigation terminal displays comprehensive route information in text. Upon request for the preview in image, the navigation terminal generates preview information about each node point on the optimum route based on the route guidance data and displays the preview information in image.

12. A route guiding method in a navigation system comprising an information center including a map database, a navigation terminal located within a moveable object including a mobile terminal, wirelessly connected to a wireless network, and an ITS (Intelligent Transportation System) terminal with a GPS (Global Positioning System) device for detecting a current location of the moveable object, and the wireless network for connecting the information center and the navigation terminal wirelessly, the method comprising the steps of:
-
receiving route guidance data by which the moveable object is guided to a destination via a plurality of node points in an optimum route at the navigation terminal from the information center; and
displaying route information about some of the node points in text if a user requests a preview of the optimum route, and displaying the preview information sequentially.
