S3：CPE客户端3-2接收到移动用户的业务需求后，把移动用户的业务需求封装到VPN隧道，并将其通过列车天线3-1发送到无线基站子系统2；
S4：无线基站子系统2将移动用户的业务需求以及无线基站子系统2自身的业务需求传输到解析与监控服务子系统1的核心网1-4；
S5：核心网1-4直接处理无线基站子系统2自身的业务需求，把移动用户的业 务需求传输到CPE网关1-1处理；
S6：CPE网关1-1把客户车厢中的移动用户的业务需求解封装VPN隧道后，再将其传输到核心网1-4处理；
S7：移动用户的业务需求处理完后，处理结果按原路返回到移动用户终端中。
由于CPE网管1-2、车内覆盖单元网管1-3、第一基带处理单元BBU3-6、MEC服务器3-3等已作详述，因此，本实施例的具体工作流程不另作论述。
本实施例解决了移动情景下用户终端直接接入运营商4G或5G基站的时候出现的多普勒频移、掉线、切换频繁等技术缺陷问题。将多个第一射频拉远单元RRU分别安装于每列客户车厢内，按单列客户车厢划分蜂窝网,大大降低了单小区容量压力。在核心网的基础上新增CPE网关，达到了解析车载设备报文，建立与车内覆盖子系统的传输的目的。
实施例二：
如图3和4所示，本实施例与实施例一相比，基站收发模块为一体化小基站3-5；CPE客户端3-2通过光纤或网线与交换机3-4连接，而交换机3-4通过光纤或网线与MEC服务器3-3连接；多个一体化小基站3-5分别安装于每列客户车厢中，且分别通过光纤或网线与交换机3-4连接。
具体地，如图5所示，一体化小基站3-5包括第二基带处理单元BBU3-5-1、第二射频拉远单元RRU3-5-2、对外接口模块3-5-3、电源模块3-5-4以及基站同步时钟3-5-5；其中，第二基带处理单元BBU3-5-1通过对外接口模块3-5-3与交换机3-4连接；基站同步时钟3-5-5连接于该第二基带处理单元BBU3-5-1与第二射频拉远单元RRU3-5-2之间；电源模块3-5-4与对外接口模块3-5-3连接。
对外接口模块3-5-3包括网口回传WAN口、本地调测LAN口和光口回传端口。
本实施例中，第二基带处理单元BBU3-5-1和第二射频拉远单元RRU3-5-2所起的作用与第一基带处理单元BBU3-6和第一射频拉远单元RRU3-7所起的作用一致。基站同步时钟用于保证全局时钟同步，保证整板时钟稳定。
本实施例一样可以达到实施例一一样的效果。
以上所述之实施例子只为本实用新型之较佳实施例，并非以此限制本实用新型的实施范围，故凡依本实用新型之形状、原理所作的变化，均应涵盖在本实用新型的保护范围内。
