Abstract:
1. A device that provides quality of service (QoS) for wireless packet transmission between the device and a base station in a communication network lacking QoS support at a Media Access Control (MAC) layer, the device comprising: a packet classifier unit that receives packets to be transmitted and tags each received packet with a priority tag indicating a priority of the received packet and a Radio Link Protocol (RLP) tag indicating an RLP associated with the received packet; a packet queuing unit that separates the received packets into a plurality of prioritized queues based on the priority tag of each received packet, wherein the prioritized queues are organized into a plurality of packet flows such that each of the plurality of packet flows includes at least one of the prioritized queues and at least one of the plurality of packet flows includes at least a first prioritized queue and a second prioritized queue, wherein the first prioritized queue has a different priority than the second prioritized queue, wherein the first prioritized queue and the second prioritized queue have a common RLP tag, and wherein each of the packet flows associates prioritized queues having common RLP tags; and a scheduler unit that schedules packet transmissions across the communication network based on prioritization numbers of the prioritized queues, the RLP tags, and the plurality of packet flows associated with the prioritized queues.
