Claim 0:
1. A method performed by a wireless local area network (WLAN) controller for using an interface between the WLAN controller and a Policy Charging and Rules Function (PCRF) in a core network to provide quality of service (QoS) treatment for a user equipment (UE):
transmitting, by the WLAN controller to an Authentication, Authorization and Accounting (AAA) in the core network via a RADIUS based interface, a first request to authenticate the UE currently accessing the core network, wherein the first request comprises an identifier identifying the UE;
receiving, by the WLAN controller from the AAA via the RADIUS based interface, an authentication result indicating that the UE is authorized to access the WLAN in response to transmitting the first request to the AAA;
transmitting, by the WLAN controller to the PCRF via the interface between the WLAN controller and the PCRF, a second request for a policy associated with the UE, wherein the policy indicates a QoS subscribed for by a user of the UE in the core network;
receiving, by the WLAN controller from the PCRF via the interface between the WLAN controller and the PCRF, the policy associated with the UE; and
managing, by the WLAN controller, resources within the WLAN, based on the policy, to establish a session between the UE and the WLAN.
