Method for controlling access point operation in wireless communication system

1. An access point (AP) operation control method of an AP controller (APC) in a wireless local area network (WLAN) system, the method comprising:

receiving disconnection related information between an AP and at least one terminal;

determining whether a number of disconnection events occurred between the AP and the at least one terminal without a handover during a pre-configured time is greater than a pre-configured threshold based on the disconnection related information;

determining that the AP is a dummy AP if the number of disconnection events is greater than the pre-configured threshold; and

if the AP is not the dummy AP, performing a coverage hole detection and correction (CHDC) related operation for the AP.

2. The method of claim 1 , wherein the disconnection related information comprises at least one of information on the number of disconnection events, or information on a ratio of occurrences of the disconnection events in the AP.

3. The method of claim 1 , wherein if the AP is the dummy AP, the CHDC related operation is not performed for the AP.

4. The method of claim 1 , wherein if the AP is the dummy AP, a transmission power for the AP and that of another AP that is adjacent to the AP is not changed in relation to the CHDC operation for the AP.

5. The method of claim 1 , further comprising:

receiving, from the AP, indication information that indicates whether the AP is the dummy AP; and

based on the indication information, determining whether the AP is the dummy AP.

6. The method of claim 1 , further comprising, if the AP is not the dummy AP, determining whether the AP satisfies a CHDC related operation condition based on signal strength information between the AP and the at least one terminal.

7. The method of claim 6 , wherein, when the AP satisfies the CHDC related condition, the performing of the CHDC related operation comprises controlling a transmission power associated with at least one of the AP or another AP that is adjacent to the AP.

8. An apparatus of an access point (AP) controller for controlling an AP operation in a wireless local area network (LAN) system, the apparatus comprising:

a communication device configured to perform a communication with at least one AP; and

at least one processor configured to:

control the communication device to receive disconnection related information between an AP and at least one terminal,

determine whether a number of disconnection events occurred between the AP and the at least one terminal without a handover during a pre-configured time is greater than a pre-configured threshold based on the disconnection related information,

determine that the AP is a dummy AP if the number of disconnection events is greater than the pre-configured threshold, and

control to perform a coverage hole detection and correction (CHDC) related operation for the AP if the AP is not the dummy AP.

9. The apparatus of claim 8 , wherein the disconnection related information comprises at least one of information on the number of disconnection events, or information on a ratio of occurrences of the disconnection events in the AP.

10. The apparatus of claim 8 , wherein the at least one processor is further configured to, if the AP is the dummy AP, control to prevent the CHDC related operation from being performed for the AP.

11. The apparatus of claim 8 , wherein the at least one processor is further configured to, if the AP is the dummy AP, control to prevent a transmission power of the AP and that of another AP that is adjacent to the AP from being changed in relation to the CHDC operation for the AP.

12. The apparatus of claim 8 , wherein the at least one processor is further configured to:

receive, from the AP, indication information that indicates whether the AP is the dummy AP, and

determine whether the AP is the dummy AP based on the indication information.

13. The apparatus of claim 8 , wherein the at least one processor is further configured to, if the AP is not the dummy AP, control the AP to determine whether the AP satisfies a CHDC related operation condition based on signal strength information between the AP and the at least one terminal.

14. The apparatus of claim 13 , wherein the at least one processor is further configured to, when the AP satisfies the CHDC related condition, control to adjust a transmission power associated with at least one of the AP or another AP that is adjacent to the AP.

15. An access point (AP) operation method in a wireless local area network (WLAN) system, the method comprising:

storing disconnection related information with respect to at least one terminal related to an AP;

determining whether a number of disconnection events occurred between the AP and the at least one terminal without a handover during a pre-configured time is greater than a pre-configured threshold based on the disconnection related information; and

if the number of disconnection events is not greater than the pre-configured threshold, transmitting, to an AP controller (APC), information indicating that the AP is not a dummy AP,

wherein the APC is configured to perform a coverage hole detection and correction (CHDC) related operation for the AP in response to receive the information indicating that the AP is not the dummy AP.

16. The method of claim 15 , wherein the disconnection related information comprises at least one of information on the number of disconnection events, or information on a ratio of occurrences of the disconnection events in the AP.

17. The method of claim 15 ,

wherein the CHDC related operation is not performed when the AP is the dummy AP.

18. An apparatus of an access point (AP) on a wireless local area network (WLAN) system, the apparatus comprising:

a communication device configured to perform a communication with at least one network node; and

at least one processor configured to:

receive disconnection related information with respect to at least one terminal related to the AP,

determine whether a number of disconnection events occurred between the AP and the at least one terminal without a handover during a pre-configured time is greater than a pre-configured threshold based on the disconnection related information, and

control the communication device to transmit information indicating that the AP is not a dummy AP to an AP controller (APC) if the number of disconnection events is not greater than the pre-configured threshold,

wherein the APC is configured to perform a coverage hole detection and correction (CHDC) related operation for the AP in response to receive the information indicating that the AP is not the dummy AP.

19. The apparatus of claim 18 , wherein the disconnection related information comprises at least one of information on the number of disconnection events, or information on a ratio of occurrences of the disconnection events in the AP.

20. The apparatus of claim 18 , wherein the at least one processor is further configured to:

prevent the CHDC related operation when the AP is the dummy AP.
