Abstract

A method of operating a disaster prevention system by a disaster prevention center is provided. The method includes: receiving a disaster situation generation report message including disaster information from a user equipment via an access point (AP); generating disaster response information based on the disaster information; and transmitting a disaster broadcasting message including the disaster response information to the disaster prevention center through the AP.

Claims

1. A method of operating a disaster prevention system by a disaster prevention center, the method comprising:

receiving a disaster situation generation report message including disaster information from a user equipment via an access point (AP);

generating disaster response information based on the disaster information; and

transmitting a disaster broadcasting message including the disaster response information to the disaster prevention center through the AP.

2. The method of claim 1, wherein the disaster situation generation report message is transferred to from the user equipment to the AP based on a wireless local area network (WLAN).

3. The method of claim 2, wherein the disaster broadcasting message is transferred from the AP to the user equipment based on the WLAN.

4. The method of claim 3, wherein the disaster broadcasting message is broadcasted to be transferred to the user equipment.

5. The method of claim 4, wherein the disaster broadcasting message is a beacon frame.

6. The method of claim 5, wherein the disaster information includes:

identification information of the user equipment;

position information of the user equipment; and

category and level information of the disaster.

7. The method of claim 6, wherein the disaster response information includes:

information on the category and level information of the disaster;

position information of the disaster;

disaster evacuation information; and

period information of the disaster broadcasting message.

8. The method of claim 7, wherein the position information of the disaster is position information of the user equipment, and

the disaster evacuation information includes shelter position information and shelter phone number list information.

9. The method of claim 5, further comprising allocating an authentication key for participating in a disaster prevention operation to the user equipment.

10. The method of claim 9, wherein the allocating of the authentication key includes:

receiving a disaster prevention operation participation request message including the identification information of the user equipment from the user equipment; and

transferring a disaster prevention operation participation response message including the authentication key to the user equipment.

11. The method of claim 10, wherein the identification information of the user equipment is a medium access control (MAC) address.

12. The method of claim 11, wherein the authentication key is the sum of the MAC address and an equipment serial number imparted to the user equipment by the disaster prevention center.

13. The method of claim 11, wherein the authentication key is determined based on the MAC address and personal information of an owner of the user equipment.

14. A disaster prevention system comprising:

a disaster prevention center coping with disaster information reported in connection with a disaster situation sensed by a user equipment; and

a network exchanging a message between the user equipment and the disaster prevention center,

wherein the disaster prevention center includes;

a disaster report processor processing the disaster information; and

a disaster information manager generating disaster response information based on the processed disaster information and transmitting disaster broadcasting information including the disaster response information to the user equipment.

15. The disaster prevention system of claim 14, wherein the network includes:

an access point (AP) receiving a disaster situation generation report message from the user equipment to transfer the disaster situation generation report message to a core network and transmitting a disaster broadcasting message from the core network to transmit the disaster broadcasting message to the user equipment; and

the core network transmitting the disaster situation generation report message transferred from the user equipment to the disaster prevention center and receiving the disaster broadcasting message from the disaster prevention center to transfer the disaster broadcasting message to the AP,

the disaster situation generation report message including the disaster information, and the disaster broadcasting message including the disaster broadcasting information.

16. The disaster prevention system of claim 15, wherein the disaster situation generation report message and the disaster broadcasting message are transmitted based on a WLAN.

17. The disaster prevention system of claim 16, wherein the disaster broadcasting message transmitted to the user equipment by the AP is broadcasted and transmitted.

18. The disaster prevention system of claim 17, wherein the disaster broadcasting message is a beacon frame periodically broadcasted by the AP including the disaster response information.

19. A user equipment supporting disaster prevention, the user equipment comprising:

a disaster report processor sensing a disaster situation to generate disaster information and transmitting a disaster situation generation report message including the disaster information to a disaster prevention center; and

a disaster information processor receiving a disaster broadcasting message transmitted from the disaster prevention center corresponding to the disaster situation generation report message and processing and informing disaster response information included in the disaster broadcasting message,

wherein the transmission of the disaster situation generation report message to the disaster prevention center and the reception of the disaster broadcasting message from the disaster prevention center are performed by a WLAN.

20. The user equipment of claim 19, further comprising a disaster application manager managing an authentication key allocated from the disaster prevention center in order to participate in a disaster prevention operation,

wherein the user equipment includes a disaster prevention application downloaded from an application server for the disaster prevention operation.
