Portable navigation device and system, and online navigation service in wireless communication network
First Claim
1. A navigation system comprising:
- a portable communication device, the portable communication device including a subsystem wherein a user of the portable communication device may designate a first icon to represent the portable communication device and a second icon to represent a second communication device, the second communication device being identified by at least a phone number listed in a database in the first communication device; and
a navigation server, connected with the portable communication device via a network, for providing a prescribed navigation service online in response to a request of the portable communication device, wherein upon receipt of position information representing a present position of the portable communication device, the navigation server sends map information including the present position of the portable communication device, so that the portable communication device displays the first icon over a position on the map information representing the present position of the portable communication device, and the portable communication device displays the second icon over a position on the map information representing the present position of the second communication device, and the portable communication device also indicates an azimuth thereof as an angle departing from a reference direction corresponding to a north direction of the map information.

Abstract
A portable communication device comprises a GPS module for determining the present position, an electronic compass module for detecting an azimuth, a display, and a wireless communicator. Herein, the position information representing the destination and present position is transmitted towards the navigation server, which in turn provides the map information including the destination and present position, based on which corresponding icon symbols are indicated in the map displayed on the screen. In addition, the azimuth is also indicated by an angle departing from a north direction of the map information. Specifically, an azimuthal arrow symbol is displayed in proximity to the icon symbol representing the present position in the map, or the icon symbol is inclined by the aforementioned angle. Thus, it is possible to create images for navigation that are appropriately displayed on the screen and are recognizable in viewing without using expensive graphic processing.
