Signaling for parameterized quality of service (QoS) support
First Claim
1. A method for initiating a QoS action on a traffic stream with parameterized QoS expectations at a first station in a communications network, the method comprising:
- sending a QoS action signal from a higher layer signaling unit of the first station to a station management entity (SME) of the first station;
creating a first QoS action primitive at the SME of the first station, the first QoS action primitive comprising a first QoS action frame body;
issuing the first QoS action primitive to a medium access control sublayer entity (MLME) of the first station;
transmitting a first QoS action frame containing the first QoS action frame body to a second station;
receiving an acknowledgment from the second station;
creating a second QoS action primitive at a medium access control (MAC) sublayer of the first station; and
issuing the second QoS action primitive to the SME of the first station.

Abstract
The creation, modification, and deletion of a traffic stream 224 with parameterized QoS expectations between two communicating stations 205 and 207, when there is no built-in mechanism for support of parameterized QoS expectations, requires signaling of traffic characteristics and QoS parameters between the management entities such as SME 212 and MLME 214 and between the MAC entities of the communicating stations 205 and 207. Either the station 205 and 207 or a hybrid coordinator may initiate the signaling. The end result of the signaling is the creation of a new traffic stream that is used to associate user traffic to a particular set of traffic characteristics and QoS parameters, which are then used in the scheduling of the transmission of the user traffic. Another end result of the signaling is the modification of an existing traffic stream in terms of its traffic characteristics and QoS parameters.
