摘要
cdma20001xEV_DO最突出的业务特征是能够提供丰富的多媒体业务 ,可以使用现有频谱并和IS -95或cdma20001x混合组网分别传递数据业务和语音业务。本文从系统对多媒体业务的支持和无线资源管理两方面出发 ,对1xEV_DO系统无线数据业务的QoS保证机制进行了研究和探讨。
The most important feature of cdma2000 1xEV_DO system is its capability to provide a rich array of multimedia services, and to be integrated with IS_95/cdma2000 1x to deliver optimal voice and data services within existing spectrum plans. This paper focuses on how 1xEV_DO ensures the required quality of service(QoS) to the admitted data service. The wireless data service QoS assurance mechanism is analyzed in multimedia services support and radio resource management.
