R99

From R4 standard the core network of WCDMA begins to use soft switch technology to fundamentally rebuild the CS ( Circuit Switched ) domain based on R99 standard .

WCDMA核心网从R4版本开始引入了软交换技术，在R99版本的基础上对电路域进行了彻底地改造。

The HSDPA link estimate and system characteristics are analyzed and compared to traditional R99 packet service , and the relationship of throughput and coverage of HSDPA is gotten .

通过研究分析HSDPA的链路预算、系统特性，并与传统的R99分组业务做比较，得到HSDPA流量与覆盖的关系。

The task of this topic is to research and establish the Qos assess system of WCDMA ( R99 ) radio system . Not only the indicators is put out , the ways of optimization and improvement are also presented .

本课题将研究和制定WCDMA移动通信网络（R99版）的质量考核指标体系，在提出考核指标的同时对部分领域的指标给出了优化和提升的方法。
