摘要

Quality of service (QoS) support in wireless data networks becomes ever more imperative in the face of rapid introduction of multimedia services into the wireless domain. In this paper, we discuss the limitations of supporting end-to-end QoS applications in the current 1x EV-DO Release 0 system. We give an overview of the newly developed CDMA2000 standards framework that allows flow-based QoS authorization, negotiation, admission, enforcement, and accounting for 1x EV-DO Revision A systems. We investigate key QoS techniques, with an emphasis on air interface scheduling, media access control, call/flow admission, overload control, and flow classification. A video telephony (VT) application is used to demonstrate the effectiveness of these techniques. Finally, we highlight several advancements of 1x EV-DO QoS development directions.

Trends in the Quality of Care for Medicare Beneficiaries Admitted to the Hospital With Unstable Angina 11This study was supported in part by the Patrick and Catherine Weldon Donaghue Medical Research Foundation Hartford. Dr. Krumholz is a Paul Beeson Faculty Scholar. The analyses on which this publication is based were performed under Contract Number 500-96-P549, entitled “Utilization and Quality Control Peer Review Organization for the State of Connecticut,” sponsored by the Health Care Financing Administration, Department of Health and Human Services. The content of this publication does not necessarily reflect the views or policies of the Department of Health and Human Services, nor does mention of trade names, commercial products or organizations imply endorsement by the U.S. Government. The authors assume full responsibility for the accuracy and completeness of the ideas presented. This article is a direct result of the Health Care Quality Improvement Program initiated by the Health Care Financing Administration, which has encouraged identification of quality improvement projects derived from analysis of patterns of care, and therefore required no special funding on the part of this Contractor. Ideas and contributions to the authors concerning experience in engaging with the issues presented are welcomed. [O] . Krumholz Harlan M., Philbin Daniel M., Wang Yun, 1998
