RSVP/SBM based up-stream session setup, modification, and teardown for QoS-driven wireless LANs
First Claim
1. A method for setting up an up-stream communication session in a basic service set in a wireless network, the method comprising:
- receiving a first message of a protocol at a subnet bandwidth manager in a station having a point coordinator, the first message originating from an agent of a host outside the basic service set, the first message requesting to set up the up-stream communication session between a source non-point coordinator station in the basic service set and the station having the point coordinator;
extracting at the subnet bandwidth manager a quality of service parameter set and a classifier from the first message;
admitting at the subnet bandwidth manager the up-stream communication session to the wireless network based on the quality of service parameter set defining the up-stream communication session and a channel status report on a medium access control sublayer of the basic service set; and
setting up by a quality of service management entity of the station having the point coordinator, a virtual up-stream between the source non-point coordinator station and the station having the point coordinator for transporting up-stream session traffic.

Abstract
A method and system is disclosed for setting up, modifying and tearing down an up-stream communication session in a basic service set (BSS) in a wireless local area network (WLAN), so that the communication session has a defined Quality of Service (QoS). Regarding setting up an up-stream communication session, a first Path message and a first Resv message (Path/Resv message) of a RSVP protocol are detected at a designated subnet bandwidth manager (DSBM) in a station having a point coordinator (PC). The first Resv message originates from a RSVP agent of a host outside the BSS, and is a request for setting up an up-stream session between a source non-PC station in the BSS and the PC station. A QoS parameter set and a classifier from the first Path/Resv message for the session are extracted at the DSBM.

11. A system in a basic service set in a wireless network, the system comprising:
a point coordinator station, comprising; a subnet bandwidth manager to perform operations, the operations comprising; detecting a first message of a protocol, the first message originating from an agent of a host outside the basic service set, the first message requesting to set up an up-stream session between a source non-point coordinator station in the basic service set and the point coordinator station, extracting a quality of service parameter set and a classifier from the first message, and admitting the up-stream session to the wireless network based on the quality of service parameter set defining the up-stream session and a channel status report on a medium access control sublayer of the basic service set; and a quality of service management entity to perform operations, the operations comprising; setting up a virtual up-stream between the source non-point coordinator station and the point coordinator station for transporting up-stream session traffic, responsive to the up-stream session being admitted. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
