Navigation terminal and method of processing data for a navigation system
First Claim
1. A navigation terminal comprising:
- a wireless communication device connected to a network and operable to transmit and receive data over the network;
a present position detection device operable to detect a present position of a movable body; and
an instruction device operable to instruct a predetermined navigation function, wherein the present position and the instructed navigation function are transmitted by the wireless communication device over the network, and a map on which the present position is superimposed and navigation information based on the instructed navigation function are received by the wireless communication device over the network.

Abstract
A navigation terminal 2 loaded in a vehicle 1 is provided with a wireless communication device connectable to a movable communications network 3 and a present position detection device and instructs implementation of a predetermined navigation function. The gateway apparatus 4 connects the movable communications network 3 and the Internet 5 and implements protocol conversion and charging processing. A navigation server 6 acquires positional data of the vehicle 1 from the navigation terminal 2 via the Internet 5, discriminates map data to be a distribution object to the navigation terminal 2, and generates navigation information based on the instructed navigation function to provide it to the navigation terminal 2. A map search server 7 reads map data discriminated as the distribution object from a map data base 8 accumulating map data and distributes them to the navigation terminal 2 via the Internet 5.

7. A navigation terminal comprising:
-
a wireless communication device connected to a network and operable to send and receive data;
a present position detection device operable to detect a present position of a movable body;
an instruction device operable to instruct a predetermined navigation function; and
a navigation server interface operable to enable communications between the navigation terminal and a navigation server, wherein the navigation server is operable to acquire positional data corresponding to the detected present position via the network, discriminate map data to be a distribution object to the navigation terminal based on the positional data, and provide navigation information based on the instructed navigation function to the navigation terminal; and
a map search server interface operable to enable communications between the navigation terminal and a map search server, wherein the map search server comprises a memory device operable to accumulate map data and is operable to read the map data discriminated as the distribution object from the memory device to distribute it to the navigation terminal via the network.

17. A method of processing data for a navigation system, the method comprising:
-
detecting a present position of a movable body in a navigation terminal;
instructing a predetermined navigation function;
acquiring, in a navigation server and via a network, positional data representative of the detected present position;
discriminating map data based on the positional data;
providing navigation information to the navigation terminal via the network, wherein the navigation information is based on the instructed navigation function;
accumulating map data in a memory device of a map search server;
reading discriminated map data from the memory device; and
distributing the discriminated map data to the navigation terminal via the network.
