The UE disables an RF band including the second RF channel with the second RAN and reports updated RF Band Capabilities to one or both RANs.

The invention discloses a distributed media access control protocol, in particular to a proxy polling mixed access protocol for increasing the capacity of a wireless local area network. The invention designs an access strategy based on polling to avoid channel conflicts, namely, according to a partial schedule strategy designed by the protocol, the existing transmission traffic flow substitutes an AP to select next transmission traffic flow, which leads the traffic flow in a network to be transmitted in sequence in a relay way. Meanwhile, the protocol adopts an access strategy based on competition as supplement to solve problems arising when a polling decision is wrong. The partial schedule strategy of the invention provides a service differentiating system based on conditions, which promotes the fairness of services with low priority when network load is relatively low. On the basis of a strategy for forecasting queue information, the partial schedule strategy further adopts a periodic polling strategy as supplement to modify wrong polling decisions on time, so as to adapt to service arrival models. The protocol remarkably increases the capacity of networks and has good performance.
