The time unfair phenomenon of up/downlink TCP(transmission control protocal) flow in wireless network access point was studied and the problem of congestion control in wireless network access was reported. A fairness scheduling algorithm for TCP flows was proposed in wireless network. The algorithm adopts the method of fast TCP flow transmission priority, which not only ensures the throughput fairness of TCP flow, but also solves the problem that slow TCP flow occupies too much channel time. And thus the time fairness of occupying channel of TCP flow was realized. Network simulation experiments show that the new fair scheduling algorithm has better performance than the traditional algorithm and it improves overall efficiency of network.
