Abstract

A position information sharing system and method using a mobile communication system is provided. The system includes: a plurality of navigation terminals for wirelessly communicating with the mobile communication system, receiving shared position information of at least one navigation system through the mobile communication system, mapping a self position and a position based on the received position information to map data, and displaying the mapped positions; and a service providing center for performing authentication for sharing of position information between the plurality of navigation terminals, receiving the shared position information from each of the navigation terminals when the authentication is made, and transmitting the received position information to the corresponding navigation terminals.

Claims

1. A position information sharing system using a mobile communication system, the system comprising:

a plurality of navigation terminals for wirelessly communicating with the mobile communication system, receiving shared position information of at least one navigation system through the mobile communication system, mapping a self position and a position based on the received position information to map data, and displaying the mapped positions; and

a service providing center for performing authentication for sharing of position information between the plurality of navigation terminals, receiving the shared position information from each of the navigation terminals when the authentication is made, and transmitting the received position information to the corresponding navigation terminals.

2. The system according to claim 1, wherein the shared position information has information on a position and a path on a map of the corresponding navigation terminal.

3. The system according to claim 2, wherein a predetermined one of the navigation terminals receives path information from other navigation terminals, compares self path information with the received path information, and transmits the self path information to other navigation terminals to set one unified path when it is determined as the comparison result to be different.

4. The system according to claim 2, wherein a predetermined one of the navigation terminals receives path information from other navigation terminals, compares self path information with the received path information, selects a path of a navigation terminal requesting for sharing the position information among the navigation terminals when it is determined as the comparison result to be different, and transmits path information to other navigation terminals to set one unified path.

5. A position information sharing system using a mobile communication system, the system comprising:

a plurality of navigation terminals for wirelessly communicating with the mobile communication system, communicating shared position information of at least one navigation system through the mobile communication system, mapping a self position and a position based on the received position information to map data, and displaying the mapped positions; and

a service providing center for performing authentication for sharing of position information between the plurality of navigation terminals, and connecting and controlling the navigation terminals to communicate their shared position information when the authentication is made.

6. The system according to claim 5, wherein the shared position information has information on a position and a path on a map of the corresponding navigation terminal.

7. The system according to claim 6, wherein a predetermined one of the navigation terminals receives path information from other navigation terminals, compares self path information with the received path information, and transmits the self path information to other navigation terminals to set one unified path when it is determined as the comparison result to be different.

8. The system according to claim 6, wherein a predetermined one of the navigation terminals receives path information from other navigation terminals, compares self path information with the received path information, selects a path of a navigation terminal requesting for sharing the position information among the navigation terminals when it is determined as the comparison result to be different, and transmits path information to other navigation terminals to set one unified path.

9. A navigation terminal of a position information sharing system using a mobile communication system, the terminal having a displaying unit and communicating shared position information having position information and path information between a plurality of navigation terminals, using the mobile communication system, the terminal comprising:

a wireless communicating unit for communicating the shared position information;

a GPS (global positioning system) receiver for receiving a GPS satellite signal;

a map database for storing map data;

a position information processor for receiving the GPS satellite signals under a predetermined control to calculate a self position, separating and analyzing the position information and the path information from at least one of the received shared position information, and mapping the self position and a position based on the received position information to the map data; and

a controller for controlling the position information processor to receive and display the mapped data on the displaying unit.

10. A position information sharing method using a mobile communication system, the system having at least two navigation terminals for communicating shared position information and a service providing center for controlling authentication between the navigation terminals, the method comprising the steps of:

in a predetermined first one of the navigation terminals, transmitting a position information sharing message that has a self inherent number and inherent numbers of second navigation terminals other than the first navigation terminal, to the service providing center through the mobile communication system;

in the service providing center, receiving the position information sharing message, detecting the inherent numbers of the second navigation terminals, and transmitting the position information sharing message to the second navigation terminals having the inherent numbers;

in each of the second navigation terminals, receiving the position information sharing message, and when a user gives permission to share the position information, transmitting a response message responsive to the permission, to the service providing center; and

in the service providing center, upon reception of the response message, controlling and connecting the first navigation terminal and the second navigation terminals to transmit the shared position information between the first navigation terminal and the second navigation terminals.
