一种测试地铁无线网络服务质量的方法和*** 技术领域
本发明属于无线通信网络领域，尤其涉及一种测试地铁无线网络服务质量的方法和***。
背景技术
在无线通信领域，扫频仪是电信运营商/设备商进行无线基站建设、网优等工作时的重要测试工具。扫频仪是一种高精度、高速度采集无线空口信号的扫频接收设备，能扫频接收无线信号，扫频输出RSRP、SINR、RSRI、RSRQ等主要参数。同时，扫频仪还具备频谱分析功能，对指定频段进行信号功率的测量，以二维频谱图、三维频谱图、采样点信号强度轨迹图等形式展现测量结果，并具备测试数据回放和导出功能，同时配备专业的数据分析平台，具有很强的数据分析能力。然而，在高速运行的列车上，应用扫频仪进行无线基站建设、网优等工作测试时，存在以下局限性：1.不支持高速移动性：城市轨道车辆的检测设备一般放置在轨道车辆的头车，俗称TC1车厢，头车中比较适合检测设备安装的空间主要在座椅下方的8个座椅设备柜。座椅设备柜的三维空间尺寸为480*280*220(mm)，空间受限，市面上常见的扫频仪外形尺寸都比座椅柜大的多，主要是深度，扫频仪无法壁挂或者导轨方式装入座椅柜，在高速移动的列车上无法保证平稳运行。2.不支持工业级可靠性：不同于普通的网络机房或者实验室，列车头车车厢是一个高振动、高粉尘、极低或极高温等恶劣环境，属于工业级运行环境，扫频仪不能适应此环境下的长期稳定运行。3.封闭的软件平台：扫频仪是专用硬件设备，数据展现是在终端显示屏或者通过数据分析平台在PC上展现。虽然扫频仪可以收集到网络服务质量和场强数据，但其数据定义和数据展现逻辑或是设备原厂提前 定义的，如果业主想更改/定制以匹配城轨无线网络的业务场景，很难得到设备原厂的支持。
