Abstract

Provided is a system and method for sharing position information using a mobile communication system. The system includes the mobile communication system providing a short message service; at least one second navigation terminal for detecting the position information from a received position information short message, mapping the detected position information to map data, and transmitting a position information short message; and a first navigation terminal for receiving and storing a proper number of each second navigation terminal, transmitting a position information short message, receiving the position information short message from the navigation terminal, and mapping a position based on the position information to the map data.

Claims

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

the mobile communication system providing a short message service (SMS);

at least one second navigation terminal for periodically receiving a predetermined position information short message using the short message service (SMS), detecting the position information from the received position information short message, mapping the detected position information to map data, displaying the mapped position information, and transmitting a position information short message comprising self-position information in response to the received position information short message; and

a first navigation terminal for, in a position information sharing mode, receiving and storing a proper number of each second navigation terminal, transmitting a position information short message comprising self-position information to the navigation terminals having the proper numbers through the mobile communication system, receiving the position information short message from the navigation terminal in response to the position information short message, mapping a position based on the position information comprised in the received position information short message to the map data, and displaying the mapped position,

wherein the second navigation terminal transmits a position information sharing permission or denial short message representing a position information sharing permission or denial to the first navigation terminal, and the first navigation terminal analyzes the position information sharing permission or denial short message and, only when it is analyzed to be the position information sharing permission, communicates the position information short message and shares the position information directly with the second navigation terminals.

2. The system according to claim 1, wherein, if the position information sharing permission or denial short message comprises a position information sharing denial message, the first navigation terminal displays the position information sharing denial message and informs a user of a position information sharing denial.

3. A method for sharing position information using a mobile communication system, in a position information sharing system comprising the mobile communication system and at least two navigation terminals, the method comprising steps of:

in a first navigation terminal among the navigation terminals, when a position information sharing mode is set, receiving and storing proper numbers of other second navigation terminals, periodically generating a position information short message comprising self-position information, and transmitting the generated position information short message to the second navigation terminals using a short message service (SMS) of the mobile communication system; and

in each of the second navigation terminals, receiving the position information short message, detecting a position based on the position information from the position information short message, mapping the detected position to map data, displaying the mapped position, and transmitting a position information short message comprising a self-position to the first navigation terminal in response to the position information short message received from the first navigation terminal,

further comprising;

in the second navigation terminal, transmitting a position information sharing permission or denial short message representing a position information sharing permission or denial, to the first navigation terminal; and

in the first navigation terminal, analyzing the position information sharing permission or denial short message, and determining the position information sharing permission or denial,

whereby only in case where it is determined to be the position information sharing permission, the first navigation terminal and the second navigation terminal communicate the position information short message and share the position information directly therebetween.

4. The method according to claim 3, wherein, if the position information sharing permission or denial short message comprises a position information sharing denial message, the first navigation terminal displays the position information sharing denial message and informs a user of a position information sharing denial.
