Abstract:
1. A method in a wireless local area network communication device, the method comprising: at a Logical Link Control ‘LLC’ layer of a protocol stack of the device, tagging signaling frames of a traffic type for time-sensitive information that belong to a communication session with a first tag that corresponds to an access category; at the LLC layer, tagging content frames of the traffic type that belong to the communication session with a second tag that corresponds to the access category; at the LLC layer, propagating the signaling frames tagged with the first tag through a first queue; at the LLC layer, propagating the content frames tagged with the second tag through a second queue; at the LLC layer, scheduling transmission to a Media Access Control ‘MAC’ layer of the protocol stack from the first queue and from the second queue to meet a quality of service characteristic, including prioritizing transmission from the first queue over transmission from the second queue, wherein the MAC layer comprises a dedicated queue for the access category; at the MAC layer, routing the signaling frames tagged with the first tag to the dedicated queue; and at the MAC layer, routing the content frames tagged with the second tag to the dedicated queue.
