In-band QoS signaling reference model for QoS-driven wireless LANs

摘要

A station in a basic service set in a wireless local area network is disclosed. The station includes a frame classification entity (FCE), a frame scheduling entity and a QoS management entity. The FCE is logically located in a logical link control layer of the station and has a classification table containing at least one classifier entry. Each classifier entry contains a virtual stream identifier (VSID) and a frame classifier associated with a user session. The FCE receives a data frame associated with the user session The data frame contains in-band quality of service signaling information for the user session. The FCE classifies the received data frame to a selected VSID contained in a classifier entry in the classification table based on a match between an in-band frame classification information contained in the received frame and the frame classifier contained in the classifier entry.
