doc.: IEEE Submission Purpose of This Document This document is for QoS of the PAC –6.6. QoS (In TGD) –IEEE shall support prioritized services including emergency services with highest priority, various QoS classes, enabling an optimal matching of service, application and protocol requirements to resources and radio characteristics. –Definition of the QoS. –The purpose of classification QoS level for PAC. –We classify the QoS level for PAC in terms of PAC applications which is referred in application matrix. Slide 3 Jeongseok Yu et al., Chung-Ang University

doc.: IEEE Submission Definition of the QoS QoS –Quality of service (QoS) is the overall performance of a telephony or computer network, particularly the performance seen by the users of the network. –To quantitatively measure quality of service several related aspects of the network service are often considered, such as error rates, bandwidth, throughput, transmission delay, availability, jitter, etc. Slide 4 Jeongseok Yu et al., Chung-Ang University

doc.: IEEE Submission Definition of the QoS QoS –Quality of service is particularly important for the transport of traffic with special requirements. –In particular, much technology has been developed to allow computer networks to become as useful as telephone networks for audio conversations, as well as supporting new applications with even stricter service demands. Slide 5 Jeongseok Yu et al., Chung-Ang University

doc.: IEEE Submission QoS Level for PAC QoS dimensions –Data rate, Delay, Error Rate, others QoS of PAC –Each PAC application requires different data traffic –Different adequate bandwidth may be requested by each application –Especially emergency data need much reliability Slide 6 Jeongseok Yu et al., Chung-Ang University
