The embodiment of the invention provides a rail train positioning method, device and system, the method is applied to a mobile positioning service center, and the method comprises the following steps: sending a positioning request of a target train to a base station through a mobile management entity, the positioning request is used for indicating the base station to obtain positioning measurement information determined by the vehicle-mounted terminal of the target train based on the leaky coaxial cable signal; receiving positioning measurement information reported by the base station; and determining position information of the target train according to the positioning measurement information. According to the embodiment of the invention, the problem that the rail train cannot be positioned when the rail train based on a signal system breaks down in the prior art can be solved, when the train breaks down, the specific position of the train is positioned by using the leaky coaxial cable signal based on the LTE wireless communication system, and the positioning accuracy of the train is improved. And a more reliable safety guarantee is provided for train dispatching, fault processing and emergency rescue.

    本申请实施例提供了一种轨道列车定位方法、装置及系统,该方法应用于移动定位服务中心,该方法包括:通过移动管理实体向基站发送目标列车的定位请求,其中,定位请求用于指示基站获取目标列车的车载终端基于漏缆信号确定的定位测量信息;接收基站上报的定位测量信息;根据定位测量信息确定目标列车的位置信息。本申请实施例可以解决相关技术中基于信号系统的轨道列车在出现故障时无法对轨道列车进行定位的问题,当列车出现故障时,实现了基于LTE无线通信系统,利用漏缆信号定位到列车的具体位置,为列车调度、故障处理以及应急救援提供更可靠的安全保障。
