题目:CDMA2000网络优化工程实践
摘要: 伴随着3G时代的到来,CDMA技术越发受到关注。CDMA是为满足大容量、高质量、综合业务、软切换、国际漫游等方面的要求而设计的一种先进移动通信技术,它具有抗干扰性好,抗多径衰落,保密安全性高等诸多优点。
随着3G技术正式商用、CDMA用户数量增加、业务种类的多样化,以及城市建设等引起的电波传播条件的变化,便需要对网络持续不断地进行优化。网络优化工作,一方面是要对网络运行中存在的诸如覆盖不好、语音质量差、掉话、网络拥塞、切换成功率低等质量问题予以解决,使网络达到最佳运行状态;另一方面,还要通过优化资源配置,对整个网络进行合理调配的运用,以适应需求和发展的情况,最大可能地发挥设备潜能,从而获得最大的投资效益。
掉话是用户通信非正常中断,其在用户方面的负面影响最为直接,是一种严重的网络故障现象。所以确定掉话原因和解决办法,降低掉话率,在CDMA2000网络优化中非常重要。
本文介绍了移动通信的发展历程、CDMA的发展历程、CDMA2000的基本原理、CDMA2000的关键技术。最后重点结合某些掉话案例,对CDMA2000网络各种情况下的掉话,详细分析了原因并给出了解决方案。

Title: Practice of CDMA2000 work Optimization
Abstract: With the arrival of the era of the third generation, CDMA technology is attracting more is an advanced mobile technology,which is designed to meet many requirements,such as, Large capacity,high quality, comprehensive business, soft handover, international roaming.
With the official use of the third generation technology,and with the increasment of the user’s number of CDMA ,and with diversification of Business type , and with propagation conditions change of radio wave arosed by urban construction , we need optimize work work optimization,on the one hand,to solve the quality problem,such as poor coverage,poor voice quality,call drop ,network congestion,low ess rate of handover,so that to keep work In the best operating status;on the other hand,by optimizing the allocation of resources, deploying the work reasonably use to meet the needs and development of equipment to play the greastest potential to achieve the largest investment returns.
Call drop is a kind of irregular interruption,and it is a work fault phenomena,which negativily impacts on the user it is very important to make sure of the causes and solutions of call drop to reduce call drop rate in CDMA2000 optimization.
This thesis introduces the development of munications, The development of
