Description

一种定位方法及相关装置 技术领域
本申请涉及定位技术领域，尤其涉及一种定位方法及相关装置。
背景技术
近年来，随着信息技术的高速发展，定位业务逐渐变得越发重要。为了实现定位，目前也有很多定位技术，例如，新空口(new radio，NR)增强小区标识(enhanced cell ID，E-CID)定位技术等。NR E-CID定位技术其基本原理为：根据终端设备所处服务小区的服务小区ID(即cell-ID)以及服务小区方向角的朝向来确定终端设备的位置。具体的，每个小区都有一个唯一的小区ID，当终端设备在某个小区注册后，在系统的数据库中就会将该终端设备与该小区ID对应起来，只要知道该小区所处的中心位置和小区的覆盖半径、小区方向角的朝向，就可以知道终端设备所处的大致范围。从上述描述可以看出，现有的NR E-CID定位技术只能实现小区级别的定位，无法实现更加精准的定位。即，现有的NR E-CID定位技术，其定位精度不够高。因此，针对NR E-CID定位技术，如何提高定位精度是个亟待解决的问题。
发明内容
本申请实施例提供了一种定位方法及相关装置，提高了NR E-CID定位技术的定位精度。

2、定位请求消息
定位请求消息在本申请实施例中是指用于请求针对特定的终端设备的定位任务的消息。定位任务可以是即时请求(location immediate request，LIR)业务或者位置延迟请求(location deferred request，LDR)业务，通过定位任务，移动通信网络可将终端设备的位置信息或者与位置有关的定位事件告知定位任务的请求方，即定位请求方。定位服务器或者位置管理功能(location management function，LMF)网元可用于管理针对特定的终端设备的定位请求。具体地，管理定位请求消息，是指定位服务器或LMF网元可用于根据定位请求方发送的定位请求消息，向定位请求方反馈终端设备的位置信息或者向定位请求方 指示终端设备出现定位请求指示的定位事件。
即时请求业务是一种“即时请求，即时响应”的定位业务，其定位请求消息可包括LIR。在本申请实施中，定位请求方向终端设备所处的核心网网元如接入和移动性管理功能(access and mobility management function，AMF)网元或者网关移动位置中心(gateway mobile location centre，GMLC)网元发送LIR，由AMF网元或者GMLC转发给定位服务器或者核心网中的其它网元如LMF网元，以使定位服务器或者LMF网元基于LIR向定位请求方即时反馈终端设备的位置信息。
位置延迟请求业务具有延迟性，定位请求方相当于向终端设备、终端设备所处的核心网网元或其他相关网元订阅终端设备的定位报告，该报告可以在满足一定的定位事件后触发，定位事件例如，终端设备移动出或移动至某一区域、终端设备移动距离达到阈值距离或者满足预设的报告周期等等，该报告中可以携带终端设备的位置信息，和/或，该报告可用于指示满足以上的位置事件，如指示终端设备移动出或移动至某一区域等等。

Figure PCTCN2020141495-appb-000004
Figure PCTCN2020141495-appb-000005
可选的，第一指示信息为信道状态信息参考信号标识或定位参考信号标识。
其中，多个下行参考信号资源的配置信息可以包括多个第一指示信息，多个下行参考信号资源与多个第一指示信息一一对应。若第一指示信息为信道状态信息参考信号标识，则在本申请中，信道状态信息参考信号标识可以是全局的，或小区内局部的。若第一指示信息为定位参考信号标识，则在本申请中，多个定位参考信号标识中定位参考信号标识相同，则表示多个定位参考信号标识中相同定位参考信号标识所指示的发送下行参考信号的传输接收点为同一传输接收点。即，多个定位参考信号标识中同一小区或不同小区下的相同定位参考信号标识所指示的发送下行参考信号的传输接收点为同一传输接收点。
具体的，信道状态信息参考信号标识是全局的，可以理解为，多个信道状态信息参考信号标识中信道状态信息参考信号标识相同，则表示多个信道状态信息参考信号标识中相同信道状态信息参考信号标识所指示的发送下行参考信号的传输接收点为同一传输接收点。即，多个信道状态信息参考信号标识中同一小区或不同小区下的相同信道状态信息参考信号标识所指示的发送下行参考信号的传输接收点为同一传输接收点。
示例性的，下行参考信号A的资源对应CSI-RS-ID1、下行参考信号B的资源对应CSI-RS-ID2、下行参考信号C的资源对应CSI-RS-ID1，下行参考信号D的资源对应CSI-RS-ID1。其中，下行参考信号A的资源和下行参考信号C的资源为一个小区下的下行参考信号资源，下行参考信号D的资源为另一小区下的下行参考信号资源。可以看出，下行参考信号A的资源、下行参考信号C的资源、下行参考信号D的资源均对应同一CSI-RS-ID。在信道状态信息参考信号标识是全局的情况下，发送下行参考信号A的传输接收点、发送下行参考信号B的传输接收点和发送下行参考信号D的传输接收点为同一传输接收点。
具体的，信道状态信息参考信号标识是小区内局部的，可以理解为：多个信道状态信息参考信号标识中一个小区下的信道状态信息参考信号标识相同，则表示多个信道状态信息参考信号标识中一个小区下的相同信道状态信息参考信号标识所指示的发送下行参考信号的传输接收点为同一传输接收点。
示例性的，下行参考信号A的资源对应CSI-RS-ID1、下行参考信号B的资源对应CSI-RS-ID2、下行参考信号C的资源对应CSI-RS-ID1，下行参考信号D的资源对应CSI-RS-ID1。其中，下行参考信号A的资源和下行参考信号C的资源为一个小区下的下行参考信号资源，下行参考信号D的资源为另一小区下的下行参考信号资源。可以看出，下行参考信号A的资源、下行参考信号C的资源、下行参考信号D的资源均对应同一CSI-RS-ID。但是，因为下行参考信号A的资源和下行参考信号C的资源为一个小区下的下行参考信号资源，下行参考信号D的资源为另一小区下的下行参考信号资源，所以发送下行参考信号A的传输接收点和发送下行参考信号B的传输接收点为同一传输接收点，发送下行参考信号D的传输接收点不同于发送下行参考信号A的传输接收点，也不同于发送 下行参考信号B的传输接收点。
可选的，信道状态信息参考信号标识可以位于信元CSI-RS-Resource-Mobility中，或相似定义或功能的信元中，或扩展字段的信元中，或CSI-RS-Resource-Mobility的扩展字段的信元中，在此不做限制。
