Multiple Quality Control : A New Framework for QoS Control in Forward Link of 1xEV-DV Systems

• One of main issues in 1xEV-DV systems is how to support and satisfy various QoS requirements of data services and voice service simultaneously. Another main issue in 1xEV-DV systems is how to increase throughput of data services without sacrificing voice service's QoS requirements. The main motivation for our proposed architecture, MQC (Multiple Quality Control), is to use per-stream buffers in physical layer and to fully utilize air resource. The problem of existing architecture is that PDUs from only one stream can be transmitted and those PDUs may not fill out the allocated time slots. In contrast to existing architecture, MQC can multiplex several streams into one PLP(Physical Layer Packet) because MQC utilizes per-service buffers in physical layer. We also introduce a multiplexing scheme that minimizes queueing delays of realtime traffic and maximizes cell throughputs.
