Admission control for QoS-driven wireless LANs
First Claim
1. A point coordinator for a basic service set in a wireless network, comprising:
- a management entity for receiving a reservation request characterizing a quality of service session, the reservation request comprising 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 the 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.

Abstract
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 discontinuos/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.

17. A method for controlling access to a communication channel in a basic service set in a wireless network, comprising:
-
receiving, by a point coordinator, a reservation request characterizing a quality of service session, 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; performing, by the point coordinator, bandwidth management for quality of service traffic transport of the quality of service session over a medium access control sublayer for the communication channel by determining whether to grant the reservation request based on the quality of service parameter set associated with the quality of service session; and generating, by the point coordinator, channel status information related to a contention-free period and a channel bandwidth. - View Dependent Claims (18, 19, 20)
