Abstract

According to the present invention, a system and a method of controlling mobile communication terminals using global positioning system (GPS) are provided. According to the present invention, the method includes: generating a GPS signal at a GPS signal generator; receiving the GPS signal from the GPS signal generator; extracting control information from the GPS signal; and converting use modes of the mobile communication terminal by using the control information. Accordingly, use modes of the mobile communication terminal located in a place required to restrict some functions of the mobile communication terminal can be collectively and automatically converted without additional costs.

Claims

1. A method of controlling mobile communication terminals using global positioning system (GPS), comprising:

generating a GPS signal at a GPS signal generator;

receiving the GPS signal from the GPS signal generator;

extracting control information from the GPS signal; and

converting use modes of a mobile communication terminal by using the control information.

2. The method according to claim 1, wherein the GPS signal generator is located in a place that is not influenced by a signal sent from a GPS satellite.

3. The method according to claim 1, wherein the control information is one included in the GPS signal, and comprises at least one of altitude information, latitude information, longitude information and time information.

4. The method according to claim 1, wherein said converting use modes of a mobile communication terminal is to convert use mode of the mobile communication terminal into one use mode of a plurality of use modes corresponding to the extracted control information.

5. The method according to claim 1, wherein the use modes are set up to control at least one of loudness of ring tone, conversion between ring tone/vibration modes, image storage/reproduction, call transmission/reception, message transmission/reception, internet connection and file downloading of the mobile communication terminal.

6. The method according to claim 1, wherein said extracting control information is to demodulate the GPS signal into data which can be processed in the mobile communication terminal.

7. A system of controlling mobile communication terminals using global positioning system (GPS), comprising:

a GPS signal generator, located in a place that is not influenced by a signal sent from a GPS satellite, generating and sending a GPS signal to a mobile communication terminal; and

the mobile communication terminal, receiving the GPS signal from the GPS signal generator and extracting control information from the GPS signal, of which use modes are converted according to the control information.

8. The system according to claim 7, wherein the control information is one included in the GPS signal, and comprises at least one of latitude information, longitude information, altitude information and time information.

9. The system according to claim 7, wherein the mobile communication terminal comprises:

a GPS receiver receiving the GPS signal;

a GPS decoder demodulating the received GPS signal and thus extracting the control information; and

a GPS controlling part sending the control information to a micro computer unit of the mobile communication terminal and converting the use modes.

10. The system according to claim 7, wherein the use modes are set up to control at least one of loudness of ring tone, conversion between ring tone/vibration modes, image storage/reproduction, call transmission/reception, message transmission/reception, internet connection and file downloading of the mobile communication terminal.
