Abstract

Disclosed is a mobile communication system and a method for capturing information of other mobile communication terminals, that can identify criminal who harmed a user of mobile communication terminal based on information of the criminal'"'"'s mobile communication terminal by capturing information of other mobile communication terminals, located within a certain distance from the user'"'"'s mobile communication terminal when the crime happened, according to the user'"'"'s instructions in an emergency situation.

There is provided a mobile communication system for capturing information of other mobile communication terminals, comprising: a first mobile communication terminal for transmitting capture signal, location information and identification information; the second mobile communication terminals for transmitting location information and identification information of the second mobile communication terminals; and a base station for transmitting the GPS means driving signal to the second mobile communication terminals and capturing information of the second mobile communication terminals.

Claims

1. A mobile communication system for capturing information of a mobile communication terminal, comprising:

a first mobile communication terminal to transmit a capture signal, first location information of the first mobile communication terminal, and first identification information of the first mobile communication terminal; and

a base station to receive the capture signal, the first location information, and the first identification information, to transmit a global positioning system (GPS) driving signal to a plurality of second mobile communication terminals within a first range of the base station in response to receiving the capture signal from the first mobile communication terminal, and to capture information of each second mobile communication terminal located within 20 meters of the first mobile communication terminal,

wherein each of the plurality of second mobile communication terminals transmits second location information and second identification information to the base station in response to receiving the GPS driving signal.

2. The mobile communication system of claim 1, wherein the first mobile communication terminal comprises:

an instructions input part to receive a user'"'"'s instruction to capture information of the second mobile communication terminals;

a first GPS receiver to generate the first location information of the first mobile communication terminal;

a control part to generate the capture signal and the first identification information of the first mobile communication terminal, and to obtain the first location information of the first mobile communication terminal by driving the first GPS receiver, according to the instruction received through the instructions input part; and

a transceiver part to transmit the capture signal, the first identification information of the first mobile communication terminal, and the first location information of the first mobile communication terminal to the base station.

3. The mobile communication system of claim 2, wherein each second mobile communication terminal comprises:

a second GPS receiver to generate the second location information;

a control part to obtain the second location information by driving the second GPS receiver and to generate the second identification information in response to receiving the GPS driving signal from the base station; and

a transceiver part to receive the GPS driving signal from the base station and to transmit the second location information and the second identification information to the base station.

4. The mobile communication system of claim 1, wherein the base station comprises:

a transceiver part to receive the capture signal, the first location information of the first mobile communication terminal, and the first identification information of the first mobile communication terminal from the first mobile communication terminal, and to transmit the GPS driving signal to the second mobile communication terminals;

a central processing part to activate a process for capturing the information of the second mobile communication terminals, and to control the transceiver part to transmit the GPS driving signal to the second mobile communication terminals; and

a data storing part to store the second location information and the second identification information captured through the central processing part, under control of the central processing part.

5. A method for capturing information of a mobile communication terminal, comprising:

transmitting a capture signal and first location information of a first mobile communication terminal to a base station;

recognizing a location of the first mobile communication terminal based on the first location information;

transmitting a global positioning system (GPS) driving signal from the base station to each second mobile communication terminal located within a first range of the base station in response to receiving the capture signal from the first mobile communication terminal;

obtaining second location information of each second mobile communication terminal by driving a GPS receiver of each second mobile communication terminal with the GPS driving signal and transmitting the second location information of each second mobile communication terminal and identification information of each second mobile communication terminal to the base station;

determining a location of each second mobile communication terminal based on the second location information of each second mobile communication terminal; and

storing the second location information and identification information of each second mobile communication terminal having a location within a second range of 20 meters of the first mobile communication terminal.

6. The method of claim 5, further comprising:

providing the stored second location information and identification information of each second mobile communication terminal having a location within the second range of the first mobile communication terminal to an information user.
