高速铁路局界处交叉并线区域无线覆盖方案研究

Research on Wireless Coverage Solutions for Intersection and Parallel Section of the High-speed Railway at the Boundary of Railway Bureaus

当2条高速铁路在局界处交叉并线时,存在2线GSM-R无线网络切换和RBC切换的区域相近或重合问题。以雄商高铁与郑徐高铁交叉并线区域为例,当设置不同的RBC切换区位置时,对此区域的GSM-R网络覆盖方案进行研究,从MSC切换区与RBC切换区关系、工程实施难度、运营维护要求、网络优化难度等方面进行分析,给出设置不同RBC切换区时MSC切换区的设置建议。

At the intersection and parallel section of two high-speed railways at the boundary of railway bureaus,there is a problem that the GSM-R wireless network handover zone and RBC handover zone of these two railways are adjacent or overlapped.Taking the intersection and parallel section of Xiong'an-Shangqiu high-speed railway and Zhengzhou-Xuzhou high-speed railway as an example,the GSM-R network coverage solutions of the section are studied under the circumstance that different RBC handover zones are selected,from the aspects of the relationship between the MSC handover zone and the RBC handover zone,the difficulties of engineering implementation,the requirements of operation and maintenance,and the difficulties of network optimization,etc.The suggestions of MSC handover zone for different RBC handover zones are given.
