1. A congestion control method, comprising:
receiving, from a second access point, a first indication at a first access point, wherein the second access point is a neighboring access point of the first access point, wherein a first operating channel of the first access point and a second operating channel of the second access point overlap, wherein the first operating channel is an operating channel of the first access point, and wherein the second operating channel is an operating channel of the second access point; and
performing, based on the first indication, traffic control on a non-key service of the first access point, wherein performing the traffic control on the non-key service comprises sending a modification indication to a station associated with the first access point, wherein the modification indication instructs the station to modify an enhanced distributed channel access (EDCA) parameter of the non-key service that reduces channel access probability of the non-key service of the station and increases channel utilization of a key service of the station.
