城市轨道交通LTE-M服务质量测试方法

The test method of LTE-M service quality for urban rail transit

LTE-M作为新一代城市轨道交通通信系统,首先保障CBTC业务安全可靠传输,并具有综合承载PIS,CCTV等业务的能力,已经在我国城市轨道交通通信中广泛应用。文章介绍了对于LTE-M服务质量的测试方法,并针对测试终端有可能的影响,提出通过采集分析网络端接口数据的方法,利用实际网络本身真实业务进行测试,作为传统测试方法的一种补充和配合,以求尽可能真实全面地测试LTE-M网络服务质量。

As a new generation of urban rail transit communication system,LTE-M has the ability to comprehensively carry a variety of services under the premise of ensuring the safe and reliable transmission of CBTC,PIS and CCTV services,and has gradually begun to be applied in urban rail transit communication in China.This paper introduces the testing method of LTE-M quality of service,and puts forward the method of collecting and analyzing the interface data of the network end to test the real business of the actual network itself.As a supplement and cooperation of the traditional testing methods,it aims to test the LTE-M network quality of service as truly and comprehensively as possible.
