高铁沿线CDMA2000基站选址及覆盖策略研究

Research on CDMA2000 base station site selection and covering strategy along the high speed rail

针对高铁CDMA2000移动用户线状分布特性,存在集中式小区频繁切换、小区重选、位置更新及多普勒频移等问题,容易导致网络切换成功率低、掉话率高,通话质量差等缺点。文章提出了高铁CDMA2000通信基站选址、天线选择、覆盖及参数设置策略。

Against high-speed rail CDMA2000 mobile users hnear distribution characteristics, there are frequent cell switching, cell reselection, location updating and Doppler frequency shift and other issues, which easily lead to low network switching success rate, high drop rate, poor call quality and so on. This paper puts forward the strategy of high speed rail CDMA2000 communication base station site selection, antenna selection, coverage and parameter setting.
