本公开涉及通信技术领域,特别是指一种定位管理方法、装置、5G无线接入网节点及核心网节点。
背景技术
位置服务(LBS,Location Based Services)是一种通过无线通信网络或其他定位系统获取终端位置信息,再结合地理信息系统为用户提供与位置相关的各类信息的服务。基于全球卫星导航系统(GNSS,Global Navigation Satellite System)的室外定位技术已经广泛应用于各种领域,除此外,基于4G移动通信网的高精度定位技术也有效地填补了卫星导航系统定位的空白。而移动通讯网络已进入5G技术时代,因此需要研究更加简洁高效的5G定位网络架构,相对于4G LTE(长期演进)架构,这种5G定位网络架构应具有更高精度和更低时延的定位需求。
其中,(1)5G移动通信系统
在5G系统中,网络侧的节点之间大多进行有线连接,即gNB(NR NodeB,5G基站)之间通过有线链路连接,gNB和核心网节点,例如AMF(Access and Mobility Management Function,接入和移动性管理功能实体),UPF(User Plane Function,用户面功能实体)等,二者之间也是采取有线链路连接。
Ng-eNB(可接入核心网5GC的4G基站节点):node providing E-UTRA user plane and control plane protocol terminations towards the UE,and connected via the NG interface to the 5GC(提供通用通信无线电接入网E-UTRA用户平面和控制平面协议终止的节点)。具体如图1所示,图中的Xn表示Xn接口,NG表示NG接口,NG-RAN表示无线接入网。
(2)5G无线协议架构

相关技术中,定位管理功能实体位于5G的核心网中,为了完成一次定位服务,所需的信息传输过程为:AMF→LMF(LPP,终端和定位服务器之间的对等层定位协议)→AMF(NAS)→RAN→UE(终端),随后是UE→RAN→AMF(NAS)→LMF(LPP)→AMF。这样的处理流程,考虑传输时延以及处理时延,将无疑加大了定位服务的整体时延要求。
