Abstract

An object of the present invention is to provide a mobile communication terminal, a base station, a warning system and a method for controlling the mobile communication terminal which are able to inform user of a situation corresponding to a predetermined area when user exists in the predetermined area.

In order to realize the object, the mobile communication terminal according to the present invention includes a setter which sets the mobile communication terminal to be in a state able to receive a predetermined wireless signal in the case that the mobile communication terminal moves to a predetermined communication area and receives a specific control signal from a destined base station, and an informer which informs user of the mobile communication terminal that the predetermined wireless signal is received in the case that the mobile communication terminal receives the predetermined wireless signal in the state able to receive the predetermined wireless signal.

Claims

1. A mobile communication terminal, characterized by comprising:

a setter setting the mobile communication terminal to be in a state able to receive a predetermined wireless signal in the case that the mobile communication terminal moves to a predetermined communication area and receives a specific control signal from a destined base station; and

an informer informing user of the own mobile communication terminal that the predetermined wireless signal is received in the case that the mobile communication terminal receives the predetermined wireless signal in the state able to receive the predetermined wireless signal.

2. The mobile communication terminal according to claim 1, characterized in that:

the mobile communication terminal further includes a receiver receiving the specific control signal, which indicates a specific area included in the communication area, from the destined base station in the case that the mobile communication terminal moves into the communication area; and

the setter sets the mobile communication terminal to be in the state able to receive the predetermined wireless signal, when the mobile communication terminal moves into the specific area.

3. The mobile communication terminal according to claim 2, characterized in that:

the specific area is a dangerous area; and

the specific control signal includes information on the dangerous area.

4. The mobile communication terminal according to claim 1, characterized in that:

the predetermined wireless signal is a beacon which is sent from an in-car device.

5. The mobile communication terminal according to claim 1, characterized in that:

the predetermined wireless signal includes detection information which is provided by a detector detecting a state of a car or a state of a driver.

6. The mobile communication terminal according to claim 5, characterized in that:

the state of the car includes at least one out of a speed, a moving direction, a position information, a state of an accelerator, a state of a brake and size of the car.

7. The mobile communication terminal according to claim 4, characterized in that:

the in-car device is mounted in any one out of a hybrid car, an electric car and a fuel cell powered vehicle.

8. The mobile communication terminal according to claim 4, characterized in that:

the in-car device is any one out of a mobile communication terminal, a music player, a portable personal computer and a personal mobile information terminal.

9. The mobile communication terminal according to claim 1, characterized in that:

the predetermined wireless signal is a beacon which is sent by a wireless communication system such as WLAN, Bluetooth (registered trademark) or the like.

10. The mobile communication terminal according to claim 1, characterized by further comprising:

a position detector detecting a position of the own mobile communication terminal on the basis of RSCP and/or RSSI sent from a plurality of base stations.

14. A warning system, characterized by comprising:

the mobile communication terminal according to claim 1 and

the base station which sends the wireless signal to the mobile communication terminal and receive the wireless signal from the mobile communication terminal and which is described in claim 11.

11. A base station, characterized by comprising:

a sender sending a specific control signal which sets a mobile communication terminal to be in a state able to receive a predetermined wireless signal in the case that the mobile communication terminal moves into a predetermined communication area.

12. The base station according to claim 11, characterized in that:

a dangerous area is registered with the communication area; and

the specific control signal includes information on the dangerous area.

13. The base station according to claim 11, characterized by further comprising:

a monitoring apparatus which monitors the mobile communication terminal and another mobile communication terminal existing in the predetermined communication area or in the dangerous area in the case that the mobile communication terminal is in the state able to receive the predetermined wireless signal, and which issues a warning to both of the mobile communication terminal and another mobile communication terminal in the case that another mobile communication terminal which approaches the mobile communication terminal at a speed not slower than a predetermined speed is detected.

15. A method for controlling a mobile communication terminal, characterized by comprising:

a detecting that the mobile communication terminal moves into a predetermined communication area;

a sending the base station a specific control signal in the case that it is detected in the detecting that the mobile communication terminal moves; and

a setting the mobile communication terminal to be in a state able to receive a predetermined wireless signal in the case that the mobile communication terminal receives the specific control signal which is sent in the sending.

16. The method for controlling the mobile communication terminal according to claim 15, characterized in that:

a dangerous area is registered with the predetermined communication area; and

the detecting is for detecting that the mobile communication terminal moves into the dangerous area.

17. The method for controlling the mobile communication terminal according to claim 15, characterized by comprising:

a monitoring the mobile communication terminal and another mobile communication terminal existing in the predetermined communication area or in the dangerous area in the case that the mobile communication terminal is in the state able to receive the predetermined wireless signal; and

a warning both of the mobile communication terminal and another mobile communication terminal, in the case that another mobile communication terminal which approaches the mobile communication terminal at a speed not slower than a predetermined speed is detected.

18. The method for controlling the mobile communication terminal according to claim 15, characterized by further comprising:

an informing that the predetermined wireless signal is received in the case that the predetermined wireless signal is received.
