A congestion state reporting method and an access network device are provided by the present invention. The method comprises: obtaining, by an access network device, an identifier of a gateway device corresponding to bearers, and reporting to the gateway device congestion state information of a cell covered by the access network device via part of bearers from the bearers corresponding to the identifier. The method mentioned above can avoid the problem in the prior art that the congestion state is further aggravated, so that the gateway device can process the problem of cell congestion more rapidly, and can reduce the processing complexity of the gateway device in the prior art.
