摘　　要：针对高速公路上车辆位置的定位问题,以基于蜂窝网络的定位技术为基础,给出一种多基站辅助单基站计算的定位算法,并结合移动网络位置服务业务的网络结构,构建了基于蜂窝网络定位技术的高速公路车辆位置服务模型,设计了车辆定位的位置服务流程,在安卓平台上对系统进行了模拟仿真实验,结果表明,能够获取位置坐标、查询位置坐标以及上报位置信息。In order to solve the problem of expressway vehicle location, based on cellular network positioning technology, a localization algorithm of single base station assisted with multi base sta- tion is presented. Combined with network structure of service model in mobile networks, a ex- pressway vehicle location service system model based on cellular network positioning technology is proposed, and the location management process is further designed. The system functions are finalized on the Android platform, and the services of vehicle emergency and location can be pro- vided through the simulation experiment.
