摘要

室内定位技术在商业和安全领域都有重要的应用，但目前仍存在定位精度低、部署成本高等问题，对此提出了一种基于LTE网络的室内定位系统，该系统定义在华为分布式皮基站之上，通过测量移动终端设备到多个接入点的参考信号强度（RSRP）或时延（ToA）进行定位。为克服LTE中上行功率控制对终端发射信号的影响，采用多信标联合解码，将绝对的信号强度或时延转换成信号强度差或时延差进行定位；该系统依托广泛部署的LTE网络，对处于无线网络连接态的终端设备提供无缝的定位服务，不依赖第三方软件，并且不会对网络性能造成影响。实验结果显示，在商场等室内场景下，使用时延差分（TDoA）技术的华为室内定位系统的平均定位精度达到3~5 m，显示出良好的应用潜力。

Abstract

Indoor positioning technology has important applications in the business and security fields

but there are still existing problems with low positioning accuracy and high deployment costs.An indoor positioning system based on long term evolution ( LTE ) network was introduced.The system was defined on the Huawei distributed pico base station and was used to measure the reference signal strength (RSRP) or time of arrival (ToA) of mobile terminals to multiple access points.To overcome the uplink power control in LTE network

the absolute RSRP or ToA was converted to differential values.The system relied on widely deployed LTE networks to provide seamless location services to terminal devices in a wireless network connection state.It didn’t rely on third-party software or affect network performance.The experimental results show that the average positioning accuracy of Huawei indoor positioning system using time difference of arrival (TDoA) can reach 3~5 m in indoor scenarios such as shopping malls

showing good application potential.
