高铁LTE网络结构及策略研究

Study on LTE Network Structure and Strategy of High Speed Railway

阐述高铁站的通信场景,相对于市区有明显的特征,人流量大,峰值跟人们出行基本保持一致,同时存在公网与专网过渡。针对高铁场景特征,提出异频组网,均衡策略,设置过渡区域,分裂及小区均衡方案。经过验证,此方案可以很好地满足用户需求。

This paper describes the communication scenario of high-speed railway station,which has obvious characteristics compared with the urban area,with large passenger flow,the peak value is basically consistent with people’s travel,and there is a transition between public network and private network.According to the characteristics of high-speed rail scenario,different frequency networking,equalization strategy,setting transition area,splitting and cell equalization scheme are proposed.After verification,this scheme can well meet the needs of users.
