Abstract

An electronic apparatus and control method thereof are provided. The electronic apparatus includes a sensor, a communicator, and a processor configured to, based on a wireless communication between a relay device and a terminal device being sensed by the sensor, identifies whether the relay device and the terminal device is an authorized device, and based on at least one of the relay device or the terminal device being identified as an unauthorized device, controls the communicator to transmit a beacon signal including communication channel transfer information to the terminal device.

Claims

1. An electronic apparatus comprising:

a sensor;

a communicator; and

a processor configured to;

based on a wireless communication between a relay device and a terminal device being sensed by the sensor, identify whether the relay device and the terminal device is an authorized device, and

based on at least one of the relay device or the terminal device being identified as an unauthorized device, control the communicator to transmit a beacon signal including communication channel transfer information to the terminal device.

2. The apparatus as claimed in claim 1, wherein the processor is configured to generate the beacon signal by including identification information of the relay device as source information.

3. The apparatus as claimed in claim 2, wherein the processor is configured to generate the beacon signal by including identification information of the terminal device as destination information.

4. The apparatus as claimed in claim 1, wherein the communication channel transfer information includes control information to control channel transfer and channel information including target channel information,

wherein the control information includes information for instructing a transfer from a first communication channel, and

wherein the target channel information includes information for transferring from the first communication channel to a second communication channel.

5. The apparatus as claimed in claim 4, wherein the processor is configured to, based on first identification information of the first communication channel through which the wireless communication between the relay device and the terminal device is performed being acquired by the sensor, generate the beacon signal by including second identification information of the second communication channel which is different from the first communication channel in the target channel information.

6. The apparatus as claimed in claim 5, wherein the second communication channel belongs to a band which is different from the first communication channel.

7. The apparatus as claimed in claim 5, where when the terminal device accesses the second communication channel based on the second identification information, a communication which is being performed through the first communication channel between the relay device and the terminal device is blocked.

8. The apparatus as claimed in claim 1, wherein the wireless communication between the relay device and the terminal device is performed according to a standard of IEEE 802.11w.

9. The apparatus as claimed in claim 1, wherein the electronic apparatus is implemented as a Wireless Intrusion Prevention System (WIPS) device.

10. A controlling method of an electronic apparatus, the method comprising:

based on a wireless communication between a relay device and a terminal device being sensed by a sensor, identifying whether the relay device and the terminal device is an authorized device; and

based on at least one of the relay device or the terminal device being identified as an unauthorized device, transmitting a beacon signal including communication channel transfer information to the terminal device.

11. The method as claimed in claim 10, further comprising:

generating the beacon signal by including identification information of the relay device as source information.

12. The method as claimed in claim 11, further comprising:
