1. A network comprising a basic service set (BSS), the network comprising:

  • a) a point coordinator (PC) station constituting a portion of the BSS, the PC station comprising;

    a frame classification entity (FCE) located in a logical link control (LLC) layer of the PC station and having a classification table containing at least one classifier entry, each classifier entry containing a virtual stream identifier (VSID) and a frame classifier associated with a user session, the FCE receiving a data frame associated with the user session, the data frame containing in-band quality of service (QoS) signaling information for the user session, the FCE classifying 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;

    a frame scheduling entity (FSE) located in a medium access control (MAC) sub layer of the PC station and having a frame scheduling table containing at least one entry, each entry containing a VSID and a QoS parameter set associated with a user session identified by the VSID, the FSE, responsive to the classified data frame, scheduling a transmission opportunity (TO) for the classified data frame based on the at least one QoS parameter value associated with the VSID and characterizing the user session; and

    a QoS management entity (QME) that interfaces with the FCE and the FSE; and

    b) a non-point coordinator (non-PC) station constituting a portion of the BSS, the non-PC station comprising an FCE, and a QME.
