PATENTS ACT 1990 COMPLETE SPECIFICATION NAME OF APPLICANT(S): E-Lead Electronic Co., Ltd.

ADDRESS FOR SERVICE: DAVIES COLLISON CAVE Patent Attorneys 1 Little Collins Street, Melbourne, 3000.

INVENTION TITLE: Remote-end route-calculating navigation system The following statement is a full description of this invention, including the best method of performing it known to me/us:- BACKGROUND OF THE INVENTION The present invention relates to a remote-end route-calculating navigation system and more particularly to a system that is not equipped with expensive or costly navigation equipment for a navigation requester to acquire complete and instant navigation information. It is mainly made up of an information center in cooperation with a plurality of navigation requesters. The information center includes at least a main information unit having an electronic map and route calculating and navigating software, and a communication device capable of transmitting/receiving phonic and digital information. The navigation requester includes a satellite positioning device and a communication device storing the telephone number of the iiformation center and the address of the digital information network so as to provide complete information for navigation requesters.

ooooo Roads in big cities become more and more complicated for drivers to o: instantly identify as a result of rapid expansion of cities all over the world. People driving in holidays through cities to remote urban areas for fun and excitement often find themselves easily lost in the unfamiliar roads in trips. So, navigation systems have been developed and sold in markets all over the world. They are popularly adopted by drivers in recent years in modem cities all over the world due to their facilities in use. The common conventional navigation systems are equipped with a terminal having a navigation software which is made up of an electronic map and a route calculating software; and a satellite positioning device for identifying the location of each user. A user first pinpoints a target place on an electronic map and a preferred trip route is obtained through the calculation of via the terminal according to the route information on the electronic map and shown together with on a display whereby a driver can drive a car on a suggested route. This is the basic operation mode of a modem navigation system. Although it can carry out a navigation purpose, •.it still has the following disadvantages in practical use: 1.Users have to spend a lot of money to purchase a computer, electronic maps and an operation system.

2.Setting target places is relatively difficult and time consuming. Besides, general people are not good at making use of a map, not to mention using such a system ooooo without a mouse and keyboard on a vehicle, making the operation rather hard.

3. Alternation or updating of roads on an electronic map is not easy; in general an electronic map is recorded on a VCD, and a user must regularly buy a new edition of an electronic map or he or she can not cope with frequently varied road information.

P:oprssbIS5548-oI rsp.do- 12O 6 03 -3- 4. Sometimes, the calculated routes are rather unreasonable and can not be corrected.

It can be seen that people spending a lot fortune on such a navigation system can not be satisfied with the outcome of navigation. Finding the problem with the conventional navigation systems, the present inventor provides for a navigation method and equipment, using an information center in combination with a plurality of navigation requesters for the users to acquire instant and ready navigation on roads.

Therefore, the primary object of the present invention is to provide a simple, complete and cheap navigation system and method which helps drivers, or to at least provide a useful alternative to the prior art.

The communication protocol unit 22 is stored with a wireless **communication protocol, a satellite positioning signals coding protocol, a digital information transmitting protocol and other various protocols and codes and decodes indispensably required.

The memory unit 23 is adapted for recording data including information downloaded from the information center, displaying information or inputting information.

The orientation calculating unit 21 is used to receive signals from a satellite positioning device for consecutive usage.

The satellite positioning device 1 is used to receive signals from satellites.

Referring to Fig. 3A,3B,3C, the flow chart of the present invention is illustrated.

1.A user activates the system of the present invention to operate by way of the man-to-system interface 28 of the communication device 2.

2. Receiving satellite signals by way of the satellite positioning device 1 and transforming the received signals into available digital data by way of the orientation calculating unit 21; temporarily storing the data in the memory unit 23 and pinpointing corresponding locations by way of the a longitude/latitude contrasting and ":calculating unit 24.

3.The communication device 2 (a cellular phone or other wireless communication device) is connected to the information center A and is able to feed back to the information center A of its instant position.

ooooo 4. A user orally informs the operators in the information center A of his or her intended driving destination.

The position, direction and destination of the user is pinpointed on the electronic map of the information center A.

6. A proper route is calculated by a main information unit in the infcrmation center 7. Transforming the calculated route including turns, road conditions, distances and etc. into protocol based signals to the user.

8.The wireless communication equipment 3 in the communication device 2 of the user receives the information delivered from the information center A and it is checked if the whole information is completely received. If it is completely received, then the connection to the information center A is cut off 9.The received protocol based signals are decoded by the communication protocol unit 22 and are temporarily stored in the memory unit 23.

The longitude/latitude contrasting and calculating unit 24 in the communication device 2 contrasts the coordinates of itself with that of the electronic map downloaded from the information center A.

11. The data obtained from the contrast of longitude and latitude by the S" longitude/latitude contrasting and calculating unit 24 is used to 'ontrol the voice synthesizer unit 25 to output indication messages such as acoustic instructions of to move forward or to back up, to turn left (right) at a certain distance or to display by way of monitor.

12. As the user is on the move, the longitude/latitude contrasting and calculating unit 24 of the communication device 2 will pick up signals from satellites and check if the user is moving in a right direction with a right distance. If not, the procedure of the step 11 will be run again until a target destination is reached..

It can be clearly seen from the above cited procedures that a user has only to press a button and orally indicate the target destination to complete a setting of navigation. Moreover, since the travelling routes are all provided by an information center, so, such routes can be instantly varied according to the road or traffic conditions, such as traffic jam, closing of roads, accidents and etc.. Thereby, it is more user friendly and the purchasing and installation cost are greatly reduced..

Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.

The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that that prior art forms part of the common general knowledge in Australia.
