ADMISSION CONTROL FOR QoS-DRIVEN WIRELESS LANS

摘要

A method and 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. For example, 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 QoS application (session/application) that can be of a continuous/periodic 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.

1. A point coordinator for a basic service set in a wireless network, comprising:
a management entity for receiving a reservation request, wherein the reservation request comprises a quality of service parameter set and a request for requesting a resource of a communication channel in the basic service set for the quality of service session; an admission control entity for performing bandwidth management for quality of service traffic transport of the quality of service session over a medium access control sublayer for the communication channel, and for determining whether to grant the reservation request based on the quality of service parameter set associated with a quality of service session; and a frame schedule entity for providing the management entity with channel status information related to a contention-free period and a channel bandwidth.
