A method for controlling uplink traffic of an access network includes: a resource and admission control subsystem (RACS) controls both a customer premise equipment (CPE) and an access node (AN), then the CPE and the AN are combined together to control the uplink data traffic. There are also a system and an apparatus for controlling the uplink traffic of the access network. By using the scheme of the present invention, the quality of service QoS of the user service in the AN could be ensured; it is easy to implemented that the AN schedules the data traffic based on the priority and the logical circuit, so the complexity of the AN equipment is reduced, meanwhile, the CPE could not send the data traffic which is greater than the authorized bandwidth, thereby the impact of the network traffic from the malicious user will be avoided effectively; and besides, the RACS controls both the AN and the CPE collectively, thereby the consistency that the AN and the CPE learn and perform the traffic policy could be ensured, and the QoS of the user service could be ensured effectively.
