信息交互方法、装置、基站及定位管理功能实体
相关申请的交叉引用

技术领域
本公开涉及通信技术领域,尤其是指一种信息交互方法、装置、基站及定位管理功能实体。
背景技术
目前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。
由于日趋涌现的新应用和场景对定位的时延和安全性等提出了更高的要求,基于当前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终端测量和计算的时间,定位服务器计算的时间,各中间节点(比如认证管理功能AMF和基站的处理时间)以及节点间传输的时延。相关技术中,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,目前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,但根据相关技术中的架构和流程,定位的数据需要发送给AMF,通常情况下核心网的AMF是集中部署的,且部署在网络中较高的位置。因此,当前的架构无法满足某些垂直行业应用的安全性要求。
