Abstract

A profile-based quality of service (QoS) priority assignment mechanism can be implemented in a wireless communication network. In one embodiment, a plurality of network identifiers (e.g., SSIDs) associated with a plurality of client network devices that are communicatively coupled with an access point of the wireless communication network are determined. It is further determined which QoS profile of a plurality of QoS profiles supported by the access point is associated with each network identifier associated with each of the plurality of client network devices. A plurality of pending communications associated with the plurality of network devices are detected. A QoS transmission priority level is assigned to each of the pending communications associated with the plurality of network devices based, at least in part, on the QoS profile associated with each pending communication. A transmission of data associated with one of the plurality of pending communications is initiated based, at least in part, on the QoS transmission priority level assigned to each pending communication.
