Abstract

Provided is a method of connecting an access point (AP) device from among a plurality of AP devices on a same network to a terminal. The method includes registering, by the AP device, media access control (MAC) address information regarding at least one or more terminals; receiving a connection request to the AP device from the terminal; and comparing the MAC address information regarding the terminal extracted from the connection request to the registered MAC address information and determining whether to connect the terminal to the AP device.

Claims

1. A method by which an access point (AP) device from among a plurality of AP devices on a same network establishes a connection to a terminal, the method comprising:

registering, by the AP device, media access control (MAC) address information regarding at least one or more terminals;

receiving a connection request to the AP device from the terminal; and

comparing the MAC address information regarding the terminal extracted from the connection request to the registered MAC address information and determining whether to connect the terminal to the AP device.

2. The method of claim 1, wherein, in the determining, if the registered MAC address information is identical to the MAC address information regarding the terminal, the terminal is connected to the AP device, and,

if the registered MAC address information is not identical to the MAC address information regarding the terminal, the terminal is not connected to the AP device.

3. The method of claim 1, wherein the same network refers to networks using a same service set identifier (SSID).

4. The method of claim 1, wherein the registering further comprises receiving MAC address information regarding the at least one or more terminals via an external device.

5. The method of claim 4, wherein the external device receives the MAC address information regarding the at least one or more terminals by using at least one of a radio frequency identification (RFID) and an near field communication (NFC).

6. The method of claim 4, wherein the external device receives the MAC address information regarding the at least one or more terminals by using a quick response (QR) code.

7. The method of claim 1, further comprising deleting the registered MAC address information at a pre-set time interval.

8. The method of claim 2, further comprising, if MAC address information identical to the registered MAC address information is received once again while the terminal is being connected to the AP device, deleting the registered MAC address information regarding the terminal.

9. The method of claim 1, further comprising:

receiving MAC address information regarding at least one or more terminals registered to another AP device on the same network from a server;

comparing the registered MAC address information to MAC address information registered to the other AP device; and

,

if the registered MAC address information is identical to the MAC address information registered to the other AP device, deleting the MAC address information registered to the other AP device.

10. A method by which a terminal establishes a connection to one access point (AP) device from among a plurality of AP devices on a same network, the method comprising:

transmitting, by the terminal, a connection request to the AP device; and

determining whether to transmit a connection request to another AP device based on a decision of the AP device regarding the connection request,

wherein the AP device compares the MAC address information regarding the terminal extracted from the connection request to MAC address information registered in advance and determines whether to connect the terminal to the AP device.

11. The method of claim 10, wherein, in the determining, if the terminal is connected to the AP device, a connection request is not transmitted to the other AP device, and,

if the terminal is not connected to the AP device, a connection request is transmitted to the other AP device.

12. An AP device that establishes a connection to a terminal, the AP device comprising:

a registerer, which registers MAC address information regarding at least one or more terminals;

a communicator, which receives a connection request to the apparatus from the terminal; and

a controller, which compares the MAC address information regarding the terminal extracted from the connection request to the registered MAC address information and determines whether to connect the terminal to the AP device,

wherein the AP device is one of a plurality of AP devices on a same network.

13. The AP device of claim 12, wherein, if the registered MAC address information is identical to the MAC address information regarding the terminal, the controller connects the terminal to the AP device, and,

if the registered MAC address information is not identical to the MAC address information regarding the terminal, the controller does not connect the terminal to the AP device.

14. A terminal that establishes a connection to an AP device, the terminal comprising:

a transmitter, which transmits a connection request to the AP device; and

a determiner, which determines whether to transmit a connection request to another AP device based on a decision of the AP device regarding the connection request,

wherein the AP device compares the MAC address information regarding the terminal extracted from the connection request to MAC address information registered in advance and determines whether to connect the terminal to the AP device.

15. The terminal of claim 14, wherein, if the terminal is connected to the AP device, the determiner does not transmit a connection request to the other AP device, and,

if the terminal is not connected to the AP device, the determiner transmits a connection request to the other AP device.
