中国神华重载铁路新一代LTE-R网络架构演进研究

Research on the Evolution of New Generation LTE-R Network Architecture of Shenhua Energy Compang Limited Heavy Haul Railway

在朔黄铁路既有LTE-R升级改造、国家能源集团计划建设统一网络之际,本文研究提出一种面向中国神华重载铁路的新一代LTE-R网络架构,并预留5G-R网络演进条件。针对核心网,提出采用4G/5G一体化核心网,采用云化架构、异地冗余部署,研究比较统一设置核心网和分散设置核心网两种组网方案并给出选择建议;针对无线接入网,提出采用TDD网络制式,给出频率使用方案,研究比较同频交织、单网+板卡冗余、双网主备、双网双活等4种组网方案并给出选择建议。最后,提出LTE-R网络向5G-R网络演进的方案。

As the existing LTE-R of Shuohuang railway is going to be upgraded and China Energy Investment Corporation plans to build a unifed network,this paper studies and proposes a new generation LTE-R network architeeture for China Shenhua heavy haul railway,and reserves the funetion for 5G-R ewolution condtions.For the core network,4G/5C integrated core network,Cloud Architecture and remote redundant deployment are proposed,two networking schemes of unifed core network and decentralized core network are studied and compared,and seleetion suggestions are given.For the wireless access network,the TDD network system is proposed,the frequency schemes are given,four networking schemes of the same frequency interleaving,single network+board redundaney,dual network active standby,and dual network active are studied and compared,and the seleetion suggestions are given.Finally,the scheme of LTE-R network evolution to 5C-R is given.
