Abstract: The invention provides a method, an apparatus and a system for controlling network congestion. The method includes: sending a control frame or a beacon frame to a station in a network when network congestion occurs, so as to instruct the station to enlarge a contention window when the station needs to send data. The method can achieve the congestion control for a network before collision occurs to a station, avoiding more serious network congestion caused by each station still contending for a channel after the network congestion occurs; since an access point can send a control frame or a beacon frame to the station when determining that congestion occurs to the current network, to instruct the station which needs to send data to re-determine a backoff time, a rapidly congestion relief of the whole network is achieved, and also a fair channel contention of each station is guaranteed.
