Apparatus for controlling load balance of multi-access points in wireless LAN system and method thereof

A method of controlling load balance of multi-access points in a wireless local area network system including a plurality of wireless local area network terminals and a plurality of access points, the method comprising:

• periodically monitoring load states of the access points;
• transmitting a load increase suppressing signal to access points whose load values exceed a threshold value, when there are the access points whose load values exceed the threshold value and there are idle access points around the access points while monitoring the load states of the access points;
• and
• suppressing an increase of load in the corresponding access points according to the transmitted load increase suppressing signal.

An apparatus, comprising:

• a plurality of wireless network terminals having wireless network interfaces and receiving a wireless network service;
• a plurality of access points providing the wireless network service to the wireless network terminals, periodically transmitting load state information, and suppressing an increase of load when a load suppressing signal is received;
• and
• a first unit comparatively evaluating load states of each access point by receiving the load state information from the access points, and transmitting a load increase suppressing signal to access points whose load values are more than a threshold value, when there are access points whose load values are more than the threshold value and other access points around the access points whose load values are more than the threshold value are in an idle state.

A computer-readable medium having computer-executable instructions for performing a method of controlling load balance of multi-access points in a wireless local area network system including a plurality of wireless local area network terminals and a plurality of access points, the method comprising:

• periodically monitoring load states of the access points;
• transmitting a load increase suppressing signal to access points whose load values exceed a threshold value, when there are the access points whose load values exceed the threshold value and there are idle access points around the access points while monitoring the load states of the access points;
• and
• suppressing an increase of load in the corresponding access points according to the transmitted load increase suppressing signal.

A computer-readable medium having stored thereon a data structure, comprising:

• a first field containing data representing periodically monitoring load states of the access points;
• a second field containing data representing transmitting a load increase suppressing signal to access points whose load values exceed a threshold value, when there are the access points whose load values exceed the threshold value and there are idle access points around the access points while monitoring the load states of the access points, with the second field of transmitting the load increase suppressing signal comprising the sub-fields of:
• a first sub-field containing data representing deciding whether there are access points whose load values exceed the threshold value based on the load state information received from the multi-access points;
• a second sub-field containing data representing repeating from the first field of periodically monitoring load states of the access points when there are no access points whose load values exceed the threshold value after deciding;
• a third sub-field containing data representing deciding whether there are neighboring idle access points when there are access points whose load values exceed the threshold value after deciding;
• a fourth sub-field containing data representing repeating from the first field of periodically monitoring load states of the access points when there are no neighboring idle access points after deciding;
• and
• a third field containing data representing transmitting the load increase suppressing signal to the access points whose load values exceed the threshold value when there are neighboring idle access points after deciding;
• and
• a fourth field containing data representing suppressing an increase of load in the corresponding access points according to the transmitted load increase suppressing signal.
