Abstract:The combination of high-precision indoor positioning technology and small cell communication network can effectively reduce the cost of deployment and operation and maintenance, and provide important solutions for various positioning application scenarios. Firstly, the common positioning technologies were summarized and compared, and the feasibility of different positioning technologies in small cells was further analyzed. Then, an indoor positioning scheme based on small cells was proposed, and its architecture was described in detail. The scheme had the advantages of easy expansion of transmission network, flexible transmission path and open positioning interface. Finally, the application scenarios and positioning processes of the two positioning technologies selected based on this scheme were presented. The results show that the indoor positioning scheme based on small cells can meet the positioning needs of the consumers and a wider range of vertical industries, which has great significance and application prospects.

室内定位技术目的是获取室内设备或用户的位置信息,由于信号遮挡等原因,卫星定位已无法满足人们对室内位置信息的需求,因此涌现出了多种室内定位技术,常见的有Wi-Fi、蓝牙、UWB、5G定位等,但目前室内定位领域仍有许多问题亟待解决。如需要对传输网络进行规划部署及后期运维,投入较大;室内定位技术百花齐放,但不同厂商兼容性不高,缺乏统一规范体系。面对这些挑战,将室内定位网络与通信网络结合能够有效解决这些问题。
随着移动通信网络的发展,5G从消费者领域逐渐向更加广泛的垂直行业发展,部署成本低、灵活性强的5G小基站已成为室内覆盖问题的主要解决方案。借助通信网优势,室内定位信息可以复用5G小基站通信网络实现定位数据的汇聚、融合及传输,避免定位网络的重复部署;通过规范定位设备与通信网的接口,促进室内定位产业健康有序发展。将室内定位技术与小基站通信网络相结合,具有天然优势,两者互相促进,共同推动产业界蓬勃发展。
本文首先介绍并对比了常用定位技术,然后讨论了不同定位技术在小基站通信网络应用的可行性;接着,提出了基于小基站通信网的室内定位方案,对其网络架构进行了具体分析,并从易扩展的传输网络、灵活的传输路径、开放的定位接口三方面对该方案的优势进行了具体阐述;最后给出了两种定位技术的典型应用场景及定位流程。
