Embodiment Construction

[0107] Embodiments of a navigation information requesting device and a navigation information providing device according to the present invention are explained in detail below with reference to the accompanying drawings.

[0108] Fig. 1 is a block diagram showing the structure according to the first embodiment of the present invention. In this figure, the functions and Figure 56 The units shown have the same or similar functions, and their descriptions are omitted.

[0109] For example, in Figure 56 In the shown navigation information providing system 100, the navigation information requesting device 300 installed in the allowed traveling vehicle has many target position information of all the routes, and once the vehicle arrives at the target position, it requests the navigation information providing device 200 to transmit information related to the target position. navigation information, and the navigation information providing device 200 only provides corresponding navig...

Abstract

The device includes: a current position information acquiring part that acquires current position information related to the current position of the vehicle at predetermined time intervals; a matching part that compares the target position information on the route that the vehicle passes with the current position information ; a control part, if the target position information matches the current position information, the part requests the navigation information providing device to transmit the navigation information related to the target position information through a radio link, a broadcasting station, a mobile target network and the Internet; and a display section, which displays navigation information provided by navigation information providing equipment via the Internet, moving object networks, broadcast stations and radio links.

Description

technical field [0001] The present invention relates to a technique for obtaining information about navigation, such as a route described using a markup language. More specifically, the present invention relates to applications to car navigation systems, personal computers, PDAs (Personal Digital Assistants), mobile phone terminals (PDC (Personal Digital Cellular)), PHS terminals (Personal Internet and electronic media provide a variety of routing information and additional information, such as road directions, travel guides, delivery programs, travel planning, traffic control, itinerary scheduling, entertainment and technology for local government public facilities. Background technique [0002] In recent years, with the proliferation of mobile terminals such as car navigation systems and PDAs, people can acquire various information without location restrictions. However, problems arise when mobile terminals reach saturation. For example, due to the increase in traffic, t...
