WCDMA系统的业务质量及其动态资源配置方案的研究
|
摘要
在当今Internet数据业务不断升温中，在固定接入速率(HDSL，ADSL，VDSL)不断提升的背景下，第三代移动通信发展的速度非常迅速．不同于二代系统，3G主要是为了解决人们随时随地话音通信的需求，3G具有支持不同媒体业务的能力。如何开发和规范3G的综合业务是一项重要课题。全球移动通信技术开始是各国处在各自发展状态，这一格局人为地造成了地区的隔离和通信上的差异。这必将引发全球统一移动通信制式和业务规范的需求。宽带码分多址(WCDMA)作为第三代移动通信技术的首选技术已被许多国家和地区所接受和支持。作为第三代移动通信技术研究的前沿课题之一，动态资源配置方案的研究具有重大的现实意义。国家“863”计划通信主题明确规定CDMA通信技术是重点之一，全力突破，“863”计划也积极支持CDMA创新技术的研究，与国际上CDMA新技术研究同步。
本文主要分为两大部分。第一部分，首先综述了WCDMA移动通信系统对QoS的要求及其结构。接着详细介绍了WCDMA系统的QoS分类、结构特性及各分类的性能要求和应用。针对WCDMA网络需要考虑的一些问题，提出了现有异种网络之间QoS机制的互操作性及各协议如何互相操作，以弥补各自的不足，从而使QoS结构更加完善。第二部分，提出了一种新的具有优先队列的动态资源配置方案，并设计了一种基于优先队列的动态资源配置模型。分析表明，该方案能较好地满足WCDMA通信系统的业务质量要求。
Nowadays, data traffic of Internet are continually developing and the fixed access rate (HDSL, ADSL, VDSL) are continually upgrading. The development of the third generation mobile communications system(3G) is very rapidly. Unlike the second generation mobile communications system(2G), the third mobile communications system(3G) is mainly serviced as satisfying people' s traffic demand at any moment and everywhere. It is a crucial task how to develop and standardize hybrid traffic for 3G. At the beginning, the global mobile communications are developed in all countries respectively. The situation make the region isolation and the difference of communications. It will bring the global consistent mobile communications traffic criterion. As the strongest candidate for the air interface technology of third-generation mobile communications , WCDMA has been accepted and supported by many countries and regions. As a up-to-date task for technology researches of third-generation mobile communications, it provides with
realistic and important significance that researches dynamic resource scheduling(DRS). CDMA communications technology is a keystone regulated definitely by national "863" plan. According to "863" plan, we must make our efforts to research new technologies about CDMA, and our researches should be synchronization with international new technologies about CDMA.
This paper mostly consists of two parts. In the first part, firstly I summarize the request and structure of QoS in WCDMA mobile communications system, with that I introduce in detail QoS classes, QoS structure character and performance limitation and application of each class in WCDMA system. Considering some problems of WCDMA networks, I bring forward mutual-operation of QoS mechanism among the existing different networks and put forward how to operate among all protocols so as to offset their own deficiencies, and thus make QoS structure more perfect. In the second part, a new DRS with prioritizing queue and a
prioritizing queue-based DRS model are devised for WCDMA system. It' s better for meet the demand of QoS in WCDMA system by analyzing the model.
