Abstract
A method and a system for a quality of service (QoS) point coordinator (PC) for a basic service set (BSS) in a wireless local area network (WLAN) is disclosed. The PC includes a QoS management entity (QME) and an admission control entity (ACE). The QME receives at least one reservation request message that characterizes one of a QoS session and a QoS application (session/application) that can be of a continuoustperiodic flow type that is time sensitive, or can be of a discontinuous/bursty flow type that is time tolerant. The reservation request message contains at least one QoS parameter set and requests a resource of a communication channel in the BSS for the QoS session/application. The communication channel is organized into superframes, such that each superframe includes a contention-free period (CFP) and a contention-period (CP). The reservation request message requests apredetermined bandwidth of each CFP of the communication channel in the BSS. The ACE performs macro bandwidth management for QoS traffic transport of the session/application over a medium access control (MAC) sublayer for the communication channel by determining whether to grant the reservation request based o…
