摘　　要：高铁上,手机要在高速移动的情况下保持通话,需在高铁沿线站点间发生大量切换,因此做好针对高铁网络之间的切换优化将十分重要。通过对高速铁路的CDMA网络特点进行理论分析,结合实际优化经验以及具体案例分析,探讨了高铁CDMA网络几种切换的优化方法。When a mobile phone keeps talking in the condition of high-speed movement, it undergoes a large number of switches along high-speed railway lines. Therefore, switches between high-speed railway networks are very important. Firstly, characteristics of high-speed railway CDMA network were analyzed. Then, combined with specifi c cases, several switch optimization methods of high-speed railway CDMA network were discussed.
