摘要
网络覆盖状况是衡量移动通信网络性能优劣的关键,CDMA2000网络的覆盖、容量和质量相互制约。在参与中国电信CDMA2000网络优化过程中,整理了部分与覆盖问题有关的案例,对网络覆盖中的典型问题之弱覆盖、越区覆盖、前反向链路不平衡及导频污染的现象、判断依据及优化方法进行了分析,并列举了相关实例,对从事网络优化工作者有一定的借鉴意义。
Network coverage state is the key judgment for a mobile network performance. The network coverage,capacity and quality of CDMA2000 restricts each other. During the network optimization process of China telecom CDMA2000,some of the cases related to the coverage problem are summed up. The phenomenon,reasons of judgment and optimization methods of typical problems in network coverage such as poor coverage,cross-boundary coverage,imbalance of front reverse link and pilot pollution are analyzed. And the relevant examples are listed,which can provide a certain reference significance to network opti-mization workers.
