摘要
网络优化是ＣＤＭＡ系统实际运营过程中的一个重要环节。本文在简介ＣＤＭＡ系统网络优化工具的基础上，详细描述ＣＤＭＡ系统网络优化的全过程。最后，对网络优化中常见的掉话现象进行了讨论，并指出其解决方法。
Network optimization
is a key link to the operation of CDMA systems. This paper introduces tools used for optimizing
CDMA network, and detaily describes the whole process of CDMA network optimization, discusses
the 'calldrop' problems which are usualy happened during optimization, and points out the way to
