Patent ID: 7433309

Claim:
An apparatus for controlling load balance of multi-access points in a wireless local area network system, the apparatus comprising: a plurality of wireless local area network terminals having wireless local area network interfaces and receiving a wireless local area network service; a plurality of access points for providing the wireless local area network service to the wireless local area network terminals, for periodically transmitting load state information, and for suppressing an increase of load when a load suppressing signal is received; and a management system for comparatively evaluating load states of each access point by receiving the load state information from the access points, and for 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; wherein, when transmitting an authentication failure message according to an authentication request of the wireless local area network terminals, the management system transmits information on other neighboring access points in the idle state to the access points whose load value exceed the threshold value, the access points transmit the information on the other neighboring access points in the idle state to the wireless local area network terminals, and the wireless local area network terminals receive the information on the other neighboring access points in the idle state from the access points and attempt access to the other access points in the idle state.
