摘要

5G蜂窝网络在为终端提供无线通信功能的同时，还可以提供定位功能。首先简要概述3GPP 5G定位技术，接着提出5G室内定位技术路线，包括云边协同一体化定位架构、5G+X融合定位方案，以及智慧园区5G定位解决方案，详细分析了智慧园区5G定位架构和流程。这些定位方案路线可无缝解决GNSS信号无法到达区域的人或物的位置定位问题，满足不同场景下的定位精度和定位时效性需求。相关技术方案已落地行业应用，具有米级定位精度和秒级时效性，得到客户的良好评价。

Abstract

The 5G cellular network not only provides wireless communication capabilities for terminals but also offers positioning functionalities.Firstly

the 3GPP 5G positioning technology was briefly outlined

followed by the proposal of the 5G indoor positioning technology road-map.The cloud-edge collaborative integrated positioning architecture

the 5G+X fusion positioning solution

as well as the 5G positioning solution for smart parks were included

with a detailed analysis of the architecture and process.These positioning solutions seamlessly addressed the issue of locating people or objects in areas where GNSS signals cannot reach

which could meet the positioning accuracy and timeliness requirements in different scenarios.The technology solution has been applied in the industry with meter-level positioning accuracy and second-level timeliness

which has been well evaluated by customers.
