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.

室內定位技術目的是獲取室內設備或用戶的位置信息,由于信號遮擋等原因,衛(wèi)星定位已無法滿足人們對室內位置信息的需求,因此涌現(xiàn)出了多種室內定位技術,常見的有Wi-Fi、藍牙、UWB、5G定位等,但目前室內定位領域仍有許多問題亟待解決。如需要對傳輸網絡進行規(guī)劃部署及后期運維,投入較大;室內定位技術百花齊放,但不同廠商兼容性不高,缺乏統(tǒng)一規(guī)范體系。面對這些挑戰(zhàn),將室內定位網絡與通信網絡結合能夠有效解決這些問題。
隨著移動通信網絡的發(fā)展,5G從消費者領域逐漸向更加廣泛的垂直行業(yè)發(fā)展,部署成本低、靈活性強的5G小基站已成為室內覆蓋問題的主要解決方案。借助通信網優(yōu)勢,室內定位信息可以復用5G小基站通信網絡實現(xiàn)定位數(shù)據(jù)的匯聚、融合及傳輸,避免定位網絡的重復部署;通過規(guī)范定位設備與通信網的接口,促進室內定位產業(yè)健康有序發(fā)展。將室內定位技術與小基站通信網絡相結合,具有天然優(yōu)勢,兩者互相促進,共同推動產業(yè)界蓬勃發(fā)展。
本文首先介紹并對比了常用定位技術,然后討論了不同定位技術在小基站通信網絡應用的可行性;接著,提出了基于小基站通信網的室內定位方案,對其網絡架構進行了具體分析,并從易擴展的傳輸網絡、靈活的傳輸路徑、開放的定位接口三方面對該方案的優(yōu)勢進行了具體闡述;最后給出了兩種定位技術的典型應用場景及定位流程。
