相关申请的交叉引用
本申请主张在2019年1月24日在中国提交的中国专利申请No.201910069560.5的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别是指一种定位方法及系统。
背景技术
在移动互联网以及工业互联网应用中,基于位置的服务(LoCation Soltuion,LCS)发挥越来越重要的作用。为了使能这些LCS的应用,快速的获取终端精准的定位信息成为关键。
5G中终端定位的架构,如图1所示,UE(User Equipment,用户设备或者终端)通过Uu接口与接入网连接,接入网包括:多个网络设备(如基站gNB),接入网通过NG-C接口与核心网的AMF(Access Management Function,接入管理功能)连接;AMF通过NLs接口与LMF(Location Management Function,定位管理功能)连接,LMF分别与定位服务器E-SMLC(Evolved Serving Mobile Location Center,演进的服务移动位置中心)和SLP(Service Location Protocol,服务定位协议)连接。
基于相关技术中的定位架构实现终端定位的流程如图2所示,完成一次定位的服务需要包含以下两个流程:
流程1包括:
1)定位服务的客户端(Extemal Client)向GMLC(Gateway Mobile Location Center,网关移动位置中心)/LRF(Location Retrieval Function,位置获取功能实体)发送定位服务请求;
2)GMLC/LRF向AMF发送定位请求;
3)AMF向LMF发送定位请求;
4)LMF向AMF发送定位信息;
5)AMF将定位信息通过RAN(无线接入网)发送给终端。
流程2包括:
1)UE进行位置测量和计算;
2)UE通过RAN将上行位置信息发送给AMF;
3)AMF向LMF发送上行位置信息;
4)LMF向AMF反馈定位响应;
5)AMF向GMLC/LRF发送定位响应;
6)GMLC/LRF向定位服务的客户端发送定位服务响应。
基于相关技术中的架构的定位流程在支持低时延定位要求和区域安全性较高的业务存在一些问题。
时延问题:定位的时延主要包括UE测量和计算的时间,定位服务器计算的时间,各中间节点(比如AMF和gNB处理时间)以及节点间传输的时延。
根据上述图2所示的流程,定位服务器向终端发送的定位辅助数据或者定位请求均需要首先发送给核心网,然后核心网发送给基站,再发送给终端;
反过来,基站接收到的数据也需要先发送给核心网,然后再发送给定位服务器,对于有些部署在基站附近的本地定位服务,将带来额外的传输和处理时延。
安全问题:相关技术中有一类定位业务的应用场景是工业应用,比如工厂,出于安全性考虑,该垂直行业的客户不希望终端定位的数据传输至工厂区域之外,但根据图2的流程,定位的数据需要发送给AMF,通常情况下,核心网AMF是集中部署的,且部署在网络中较高的位置。因此,相关技术中的架构无法满足某些垂直行业应用的安全性要求。
