For QoS (quality of service) requirements of a session at a first access point and a wireless station, a cost function value is calculated for the specific session based on a number of network packets to be processed in the queue and the identified QoS requirement. It is determined whether another of the plurality of access points within range of the specific session can better serve the identified QoS requirement than the first access point by comparing the cost function value for the specific session against at the first access point against at least a cost function value for a second access point.
