WCDMA无线网络码资源优化

Code resource optimization of WCDMA wireless network

中国联通WCDMA网络经过两年多的大规模建设与发展,用户数量不断增加,网络负荷也逐渐增高,与用户感知密切相关的码资源也开始不足的现象,导致网络性出现波动甚至恶化,比如无线接通率降低,单用户速率下降等。通过对长沙WCDMA无线网络码资源利用情况的分析研究,从覆盖控制、双载波方案、参数优化等方面来优化解决。

After two years of development of China Unicom WCDMA network,the number of users is increasing,and the load of network also is gradually increasing,however,shortage of code resource of closely related with user-aware begin to appear,and gradulally result in that network performance began to fluctuate even to deteriorate,such as wireless successful rate is lower than before,single subscriber rate is decreasing.By analysising using of code resource of Changsha WCDMA radio network,this article aims to optimize and settele the problems from the following aspects：the cover control,dual-carrier program,parameter optimization,etc.
