Abstract

本申请公开了一种定位信息上报的方法及通信装置，该方法包括：网络设备接收终端发送的第一消息，以及向定位管理设备发送第二消息，第一消息和第二消息均包括第一定位信息，第一定位信息包括终端测量第一参考信号获得的第一测量结果；其中，第一消息承载于RRC信令，第二消息承载于NRPPa信令。由于在终端和定位管理设备之间交互的第一定位信息先后通过RRC信令和NRPPa信令承载，且由于RRC信令允许的上报周期小于LPP信令允许的上报周期，NRPPa信令对上报周期不作限制，所以可缩短上报终端的定位信息的周期，适用范围更广。

Description

一种定位信息上报的方法及通信装置 技术领域
本申请涉及定位技术领域，尤其涉及一种定位信息上报的方法及通信装置。
背景技术
在如长期演进(long term evolution，LTE)、新空口(new radio，NR)版本(release，Rel)R-16的定位架构等传统的定位架构中，终端通过终端和定位计算中心之间的定位协议(LTE positioning protocol，LPP)信令将对定位的测量结果发送给定位管理功能(location management function，LMF)。由于LPP允许终端上报定位测量结果的最小周期是250ms，上报周期较长，无法满足需要频繁地获知终端位置的需求。
发明内容
本申请提供一种定位信息上报的方法及通信装置，能够缩短定位信息上报的周期，更好地适用于较为频繁地获知终端位置的应用场景。
第一方面，提供一种定位信息上报的方法，该方法可由第一通信装置执行，第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片***。下面以所述通信设备为网络设备为例进行描述。该方法包括：
网络设备接收终端发送的第一消息，之后，该网络设备向定位管理设备发送第二消息，第一消息承载于无线资源控制(radio resource control，RRC)信令，第二消息承载于新空口定位协议副本(new radio positioning protocol annex，NRPPa)信令。其中，第一消息和第二消息均包括第一定位信息，该第一定位信息包括终端测量第一参考信号获得的第一测量结果。即在终端和定位管理设备之间交互的第一定位信息先后通过RRC信令和NRPPa信令承载。由于RRC信令允许的上报周期小于LPP信令允许的上报周期，且NRPPa信令对上报周期不作限制，所以相较于通过LPP信令在终端和定位管理设备之间交互定位信息来说，本方案可缩短上报终端的定位信息的周期，能够满足需要频繁上报终端位置的场景，适用范围更广。
在一种可能的实现方式中，在网络设备接收终端发送的第一消息之前，所述方法还包括：
网络设备接收来自定位管理设备的第三消息，该第三消息包括第一指示信息和/或第二指示信息，第一指示信息用于指示该网络设备上报第一定位信息，第二指示信息用于指示该网络设备向终端请求所述第一定位信息。其中，该第三消息承载于NRPPa信令，也就是，定位管理设备和终端之间用于请求第一定位信息的第三消息为NRPPa消息。采用该方案可进一步缩短终端的定位周期。
在一种可能的实现方式中，所述方法还包括：
网络设备向终端发送第四消息，该第四消息用于请求所述第一定位信息，该第四消息承载于RRC信令。
应理解，网络设备在第二指示信息的触发下，向终端发送第四消息，即按需请求获取 第一定位信息，更能满足实际需求。当然，网络设备也可以主动向终端请求第一定位信息，以获得较新的第一定位信息。
应理解，第一定位信息是定位终端所需要的信息中的部分信息，通过第一指示信息可明确定位管理设备需要哪些第一定位信息，例如与定位方法相关的定位信息，这样可减少不必要的定位信息的上报。
在一种可能的实现方式中，所述第一指示信息可包括如下信息中的一种或多种：邻区索引列表、定位方法、上报方式、信息采集时长；其中，
邻区索引列表包括如下索引中的一种或多种：物理小区索引、小区全局索引、传输点索引；
定位方法包括如下方法中的一种或多种：观察到达时间差(observed time difference of arrival，OTDOA)定位方法、下行链路到达角(uplink angle of arrival，DL-AOA)定位方法、下行链路离开角(downlink angle of departure，DL-AOD)定位方法；
上报方式包括周期性上报或触发上报；
信息采集时长为预设定的时间长度，该网络设备在该预设定的时间长度内多次接收终端上报的测量结果，且该测量结果是终端在所述预设定的时间长度内周期性上报的测量结果。
相应的，第一定位信息可包括：定位方法、测量结果、误差信息、邻区索引列表，其中，定位方法为如下方法中的任一种：OTDOA定位方法、DL-AOA定位方法、DL-AOD定位方法；
测量结果为所述定位方法对应的测量结果，该测量结果包括如下测量结果中的任一种：参考信号接收功率(reference signal received power，RSRP)值、参考信号时间差(reference signal time difference，RSTD)值、到达角值；

邻区索引列表包括如下索引中的一种或多种：物理小区索引、小区全局索引、传输点索引。
在一种可能的实现方式中，第一定位信息包括所述终端的下行到达角度。采用该方案可通过到达角实现下行定位，适用范围更广。
在一种可能的实现方式中，第一参考信号为定位参考信号(positioning reference signal，PRS)或信道状态信息参考信号(channel state information reference signal，CSI-RS)。由于终端和网络设备会对CSI-RS进行测量，采用该方案，不需要另外测量专用的PRS，也就不需要基站为终端配置用于发送PRS的资源，从而进一步缩短上报定位信息的周期。
第二方面，提供另一种定位信息上报的方法，该方法可由第一通信装置执行，第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片***。下面以所述通信设备为第一网络设备为例进行描述。该方法包括：

该方案与第一方面的方案类似，在终端和定位管理设备之间交互的第二定位信息通过RRC信令承载，第三定位信息通过NRPPa信令承载，可缩短上报终端的定位信息的周期。与第一方面的方案不同之处在于，该方案根据终端的第二测量结果和第一网络设备的第三测量结果确定终端的位置，可适用于终端的上下行定位方案。
在一种可能的实现方式中，第三定位信息还包括第四测量结果，该第四测量结果为至少一个第二网络设备测量第二参考信号和第三参考信号获得的测量结果。该方案中，至少一个第二网络设备可以认为是邻区基站，邻区基站可将第四测量结果通过第二网络设备和第一网络设备之间的通信接口告知第一网络设备，从而第一网络设备将第二测量结果、第三测量结果和第四测量结果一起发送给定位管理设备。
在一种可能的实现方式中，在第一网络设备接收终端发送的第一消息之前，所述方法还包括：
第一网络设备接收来自定位管理设备的第三消息，该第三消息包括第三指示信息和/或第四指示信息，第三指示信息用于指示第一网络设备上报第三定位信息，第四指示信息用于指示第一网络设备向终端请求第二定位信息，其中，第三消息承载于NRPPa信令。由于第三消息承载于NRPPa信令，所以采用该方案可进一步缩短终端的定位周期。
在一种可能的实现方式中，所述方法还包括：
第一网络设备向终端发送第四消息，该第四消息用于请求所述第二定位信息，该第四消息承载于RRC信令。
应理解，网络设备在第四指示信息的触发下，向终端发送第四消息，即按需请求获取第二定位信息，更能满足实际需求。当然，网络设备也可以主动向终端请求第二定位信息，以获得较新的第二定位信息。
应理解，第二定位信息和第三定位信息均是定位终端所需要的信息中的部分信息，通过第三指示信息可明确定位管理设备需要哪些第二定位信息和第三定位信息，例如与定位方法相关的定位信息，这样可减少不必要的定位信息的上报。

定位方法包括多往返时间(Multi round trip time，Multi-RTT)定位方法；
上报方式包括周期性上报或触发上报；
信息采集时长为预设定的时间长度，第一网络设备在所述预设定的时间长度内多次接收所述终端上报的测量结果，该测量结果是终端在所述预设定的时间长度内周期性上报的测量结果。
相应的，第三定位信息包括：定位方法、测量结果、误差信息、邻区索引列表；其中，
定位方法为Multi-RTT定位方法；
测量结果为所述定位方法对应的测量结果，该测量结果包括终端内部的接收和发送时延误差、第一网络设备内部的接收和发送时延误差，以及至少一个第二网络设备内部的接收和发送时延误差；
误差信息用于指示测量结果的准确度，该误差信息包括如下信息中的一种或多种：误 差值、误差范围、误差分布类型；
邻区索引列表包括如下索引中的一种或多种：物理小区索引、小区全局索引、传输点索引。
应理解，该第二方面的方案可用于终端的上下行定位，所以在一种可能的实现方式中，第二参考信号作为下行参考信号，可以是PRS或CSI-RS，第三参考信号作为上行参考信号可以是探测参考信号(sounding reference signal，SRS)。

应理解，终端通过网络设备与定位管理设备进行交互，终端与网络设备之间交互的第一定位信息承载于RRC信令，相较于通过LPP信令承载第一定位信息来说，可缩短终端与定位管理设备交互信息所用时长，有助于缩短上报终端的定位信息的周期。
在一种可能的实现方式中，第五消息是由第六消息触发的，该第六消息是由定位管理设备发送给网络设备的，该第六消息承载于NRPPa信令。即终端和定位管理设备之间用于请求第一定位信息的消息为NRPPa消息，可缩短终端的定位信息的上报周期。
在一种可能的实现方式中，第一参考信号为PRS或CSI-RS。
关于第三方面或第三方面的各种可能的实施方式所带来的技术效果，可以参考对第一方面、第二方面、第一方面的各种可能的实施方式或第二方面的各种可能的实施方式的技术效果的介绍。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实 施例作进一步地详细描述。
在介绍本申请之前，首先对本申请实施例中的部分用语进行简单解释说明，以便于本领域技术人员理解。
1)、本申请实施例中的终端(也可以称为用户设备(user equipment，UE))是一种具有无线收发功能的设备，该终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。该终端设备例如可以包括用户设备(user equipment，UE)、无线终端设备、移动终端设备、设备到设备通信(device-to-device，D2D)终端设备、车与外界(vehicle-to-everything，V2X)终端设备、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)终端设备、物联网(internet of things，IoT)终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、用户站(customer premises equipment,CPE)、固定无线接入(fixed wireless access,FWA)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的移动装置等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位***(global positioning system，GPS)、激光扫描器等信息传感设备。
作为示例而非限定，在本申请实施例中，该终端还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种终端，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
上述终端可通过运营商网络提供的接口(例如N1等)与运营商网络建立连接，使用运营商网络提供的数据和/或语音等服务。终端设备还可通过运营商网络访问DN，使用DN 上部署的运营商业务，和/或第三方提供的业务。其中，上述第三方可为运营商网络和终端设备之外的服务方，可为终端设备提供他数据和/或语音等服务。其中，上述第三方的具体表现形式，具体可根据实际应用场景确定，在此不做限制。
2)、本申请实施例中所涉及的核心网，可以包括对用户的信令和数据进行处理和转发的网络设备。例如包括AMF、会话管理功能(session management function，SMF)以及用户面网关、定位管理设备等核心网设备。其中用户面网关可以是具有对用户面数据进行移动性管理、路由、转发等功能的服务器，一般位于网络侧，如服务网关(serving gateway，SGW)或分组数据网络网关(packet data network gateway，PGW)或用户面网元功能实体(user plane function，UPF)等。AMF以及SMF相当于LTE***中的移动管理实体(mobility management entity，MME)。AMF主要负责准入方面，SMF主要负责会话管理。当然，核心网中也可以包括其他网元，这里不一一列举。
定位管理设备具有定位功能，本申请实施例涉及的定位管理设备可包括定位管理功能(location management function，LMF)或者定位管理组件(location management component，LMC)，或者可以是位于网络设备中的本地定位管理功能(local location management function，LLMF)，本申请实施例对此不作限定。为了方便描述，下述实施例均以定位管理设备为LMF为例进行介绍。
3)、本申请实施例中所涉及的网络设备，例如包括接入网(access network，AN)设备。本申请实施例中所涉及的NG-RAN，可以包括一个或多个接入网设备。NG-RAN中的接入网设备又可以称为基站，或者RAN节点，或者RAN设备；一种V2X技术中的网络设备为路侧单元(road side unit，RSU)，RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备是网络侧的一种用于发射和/或接收信号的实体，可以用于将收到的空中帧与网络协议(internet protocol，IP)分组进行相互转换，作为终端与接入网的其余部分之间的路由器，其中接入网的其余部分可以包括IP网络等。网络设备还可以协调对空中接口的属性管理。例如，网络设备可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB)，eNB是一种部署在无线接入网中满足4G标准的为终端提供无线通信功能的装置。接入网设备还可以是新无线控制器(new radio controller，NR controller)，可以是5G***中的gNode B(gNB)，可以是集中式网元(centralized unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站(也称为小站)，可以是中继(relay)，可以是分布式网元(distributed unit)，可以是各种形式的宏基站，可以是传输接收点(transmission reception point，TRP)、传输测量功能(transmission measurement function，TMF)或传输点(transmission point，TP)或者任何其它无线接入设备，或者下一代通信中的基站，但本申请实施例不限于此。网络设备也可以包括无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。
在一些部署中，基站(如gNB)可以由集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)构成，即对原LTE接入网中的基站的功能进行拆分，将基站的部分功能部署在一个CU，将剩余功能部署在DU，多个DU共用一个CU，可以节省成本，以及易于网络扩展。CU和DU的切分可以按照协议栈切分，将RRC层、SDAP层以 及PDCP层部署在CU，其余的无线链路控制RLC层、MAC层以及PHY层部署在DU。CU和DU之间可以通过F1接口连接。CU代表gNB通过NG接口和核心网连接，CU代表gNB通过Xn接口和其他gNB连接。
更进一步，CU还可以划分为CU-控制面(control plane，CP)和CU-用户面(user plan，UP)。其中CU-CP负责控制面功能，主要包含RRC和控制面对应的PDCP即PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP和用户面对应的PDCP即PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将flow映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等。其中CU-CP和CU-UP通过E1接口连接。CU-CP代表gNB通过NG接口和核心网连接。通过F1接口控制面即F1-C和DU连接。CU-UP通过F1接口用户面即F1-U和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。
4)下行链路离开角(downlink angle of departure，DAOD/DL-AOD)，为网络设备和终端之间下行电磁波传输时从网络设备处观测的电磁波离开方向，可用于对终端的定位。
5)上行链路到达角(uplink angle of arrival，UAOA/UL-AOA)，可用于对终端的定位。参与终端定位的至少两个网络设备对终端发送的SRS进行测量，可获得AOA，利用每个网络设备在对应AOA上发射的射线交点可定位终端的位置。
6)到达时间差(time difference of arrival，TDOA)，为终端发送到两个网络设备的信号的传输时间差，可用于终端的定位。按照测量对象的不同，有(downlink time difference of arrival，DL-TDOA)、(uplink time difference of arrival，UL-TDOA)。在一些实施例中，DL-TDOA也可称为UTDOA，UL-TDOA也可称为观察到达时间差(observed time difference of arrival，OTDOA)。
7)、本申请实施例中的术语“***”和“网络”可被互换使用。术语“多个”是指两个或两个以上。术语“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，a和b，a和c，b和c或a、b和c，其中a，b，c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一消息和第二消息，只是为了区分不同的消息，而并不是表示这两种消息的优先级、发送顺序或者重要程度等的不同。
图1为LTE和NR Rel-16中的定位架构的示意图，如图1所示，涉及的网元/模块主要包括下一代无线接入网络(next generation radio access network，NG RAN)、终端和核心网三部分。
其中，核心网包括定位管理功能(location management function，LMF)、接入和移动性管理功能(access and mobility management function，AMF)、服务定位协议(service location protocol，SLP)以及演进服务移动定位中心(evolved serving mobile location centre，E-SMLC)等。定位服务器即定位管理功能(location management function，LMF)连接到AMF，LMF和AMF之间通过NLs接口连接。LMF负责支持有关终端的不同类型的位置服务，包括对 终端的定位和向终端传递辅助数据。AMF可以从第5代核心网络定位服务(5th generation core network location services，5GC LCS)实体接收与终端相关的位置服务请求，或者AMF本身也可代表特定终端启动一些位置服务，并将位置服务请求转发给LMF。得到终端返回的位置信息后，将相关位置信息返回给5GC LCS实体。
NG RAN可以包括下一代节点B(next generation node B，gNB)、下一代演进型基站(next generation evolved nodeB，ng-eNB)等。gNB、ng-eNB之间通过Xn接口连接，LMF与ng-eNB/gNB通过NG-C接口连接。
终端可以测量来自NG RAN和其他来源的下行链路信号以支持定位。gNB/ng-eNB可以为终端提供测量信息，并将此信息传达给LMF。
LMF和终端之间交互的信息，例如终端能力信息传递、辅助信息传递、测量信息等，可以通过LTE定位协议(LTE positioning protocol，LPP)消息承载，LPP消息通过Uu接口和NG-C接口发送，在终端侧LPP消息将被封装为非接入层(non access stratum，NAS)信令，基站收到终端的NAS信令(基站不知道终端发的是LPP消息)后转给AMF，AMF解析NAS信令后获得LPP消息并将其交给LMF，类似的，从LMF侧发出的LPP消息封装为一个NAS信令发给基站，基站收到NAS信令之后直接转到终端。由于LPP允许终端上报定位测量结果的最小周期是250ms，上报周期较长，不能较好地适用某些场景，例如需要较为频繁地获知用户的位置，例如需要监控用户的行为轨迹等。
鉴于此，本申请实施例提供的方案采用NRPPa消息承载LMF与基站之间交互的信息。由于NRPPa消息不限制定位测量结果的上报周期，所以本方案可以缩短终端的定位周期，从而能够适用需要频繁定位的场景，使用范围更广。
本申请实施例提供的定位方法可以应用于各种通信***，例如：长期演进(long term evolution，LTE)***、第五代(5th generation，5G)***，如NR，及下一代的通信***，如6G***等。当然，本申请实施例的技术方案也可以应用于其它的通信***，只要该通信***存在对终端的定位需求即可。此外，所述通信***还可以适用于面向未来的通信技术，本申请实施例描述的***是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
图2示出了本申请实施例适用的一种通信***的网络架构，该通信***包括核心网、NG-RAN和终端。核心网包括LMF、AMF、安全用户平面定位(secure user plane location，SUPL)定位平台(SUPL location platform，SLP)以及增强服务移动定位中心(enhanced serving mobile location centre，E-SMLC)等网元/模块，NG RAN包括gNB、ng-eNB等网元/模块，其中LMF、AMF、SLP、E-SMLC、gNB以及ng-eNB等网元/模块的具体功能、各个网元/模块之间的连接关系可以参见上文图1相关部分的介绍，这里不再赘述。
与图1不同的是，图2所示的网络架构中NG-RAN中增加了LMC，LMC的具体部署方式是设置在基站内部，如设置在gNB中或设置在ng-ENB中。在这种网络架构中，LMC作为是基站内部的一个功能，因此不需要引入新的接口。
图3示出了本申请实施例适用的另一种通信***的网络架构，如图3所示，通信***同样包括核心网、NG-RAN和终端。与图2不同的是，图3所示的网络架构中的LMC在NG-RAN中作为一个独立的逻辑节点，通过一个新接口与基站相连接，例如图3中，LMC通过接口Itf与gNB-CU相连。
图4示出了本申请实施例适用的另一种通信***的网络架构，如图4所示，通信***同样包括核心网、NG-RAN和终端，LMC在NG-RAN中作为一个独立的逻辑节点，与图3不同的是，LMC可以图4经过新接口同时与多个基站连接。图4以LMC与两个基站同时相连为例，在具体实施时LMC还可以与更多的基站相连。
应理解，上述图1、图2、图3、图4仅是本申请实施例可适用的通信***的一种示例性说明，并不对本申请适用的通信***所包括网元的类型、数量、连接方式等进行具体限定。且图2-图4中虚线示意的网元/模块不是不必可少的，是可选的，例如E-SMLC或SLP不是必不可少的；或者，虚线示意的网元/模块是另一种存在形式，例如gNB或ng-eNB在一些实施例中也称为TRP，终端在一些实施例称为SET。
应理解，定位方法包括如前述的OTDOA定位方法、DL-AOA定位方法、DL-AOD定位方法、UL-AOA定位方法，Multi-RTT定位方法等，总的来说，可以归结为上行定位方法、下行定位方法和上下行定位方法。需要说明的是，这里上行和下行是相对而言的，如果基站到终端的传输方向为下行(本文以此为例)，那么终端到基站的传输方向为上行；相反，如果基站到终端的传输方向为上行，那么终端到基站的传输方向为下行。
下面结合附图对本申请实施例提供的定位方法进行详细介绍。
请参见图5，为本申请实施例提供的下行定位方法的流程图。在下文的介绍过程中，以该方法应用于图2-图4所示的通信***为例。另外，该方法可由三个通信装置执行，这三个通信装置例如为第一通信装置、第二通信装置和第三通信装置。为了便于介绍，在下文中，以该方法由网络设备、终端和定位管理设备执行为例，也就是，以第一通信装置是网络设备、第二通信装置是终端，第三通信装置是定位管理设备为例。需要说明的是，本申请实施例只是以通过图2-图4的通信***为例，并不限制于这种场景。应理解，当前终端当前接入的网络设备有一个(该网络设备可称为服务基站)，为了便于描述，下文中将该网络设备称为服务基站。在下文中，以定位管理设备是LMF网元为例，应理解，在未来通信如6G中，定位管理设备仍可以是LMF网元，或有其它的名称，本申请实施例不作限定。
具体的，本申请实施例提供的定位方法的具体流程描述如下：
S501、终端向服务基站发送第一消息，服务基站接收该第一消息，其中，该第一消息包括第一定位信息，该第一定位信息承载于RRC信令。
在本申请实施例中，服务基站可以是NG RAN中的设备，例如gNB、ng-eNB；或者，服务基站可以是LMC。如前文所述，如果LMC作为基站内部的一个功能，那么该服务基站为LMC所在的基站。如果LMC的部署方案如图3或图4，即LMC作为一个独立的逻辑节点通过接口与一个基站或多个基站连接，那么服务基站为与LMC连接的任意一个基站。
第一定位信息可以理解为是定位终端所需要的信息中的部分信息，为了完成终端的定位过程，所需要的其他定位信息，可参考现有技术，这里不再赘述。例如，该第一定位信息包括终端对基站发送的第一参考信号进行测量之后，获得的第一测量结果中的部分或全部信息。应理解，第一参考信号为下行参考信号。在一些实施例中，第一参考信号可以是PRS，也可以是CSI-RS。由于终端和基站会对CSI-RS进行测量，所以将CSI-RS作为第一参考信号，不需要另外测量专用的PRS，也就不需要基站为终端配置用于发送PRS的资源，可缩短上报定位信息的周期。
在一些实施例中，第一测量结果携带的信息元素(在下文中简称为信元)可包括RSRP值、RSTD值以及到达角中的一种或多种。例如第一测量结果包括各PRS发送波束对应的RSRP值。应理解，第一测量结果用于定位，在另一些实施例中，第一测量结果也可以包括其他可能的测量值，这里不再一一例举。
第一定位信息除了包括第一测量结果，还可以包括其他用于定位的信息。在一些实施例中，第一定位信息还可以包括定位方法，例如可包括OTDOA定位方法、DL-AOA定位方法和DL-AOD定位方法中的一种。当然，定位方法也可以包括DL-AOA的定位方法、UL-AOD定位方法等，本申请实施例对定位方法的具体实现不作限制，只要适用于下行定位即可。
在另一些实施例中，第一定位信息还可以包括用于指示测量结果的误差信息，例如第一定位信息可以包括误差值、误差范围和误差分布类型中的一种或多种。示例性的，第一定位信息包括的第一测量结果包括RSTD值，那么该第一定位信息包括的误差信息可以是RSTD质量信息，即表示RSTD值的误差值、误差范围，以及误差分布类型等信息中的一种或多种。应理解，第一定位信息包括的第一测量结果包括RSRP值，那么该第一定位信息包括的误差信息可以是RSRP质量信息；或者，第一定位信息包括的第一测量结果包括AOA值，那么该第一定位信息包括的误差信息可以是AOA质量信息。
在又一些实施例中，第一定位信息还可以包括邻区索引列表，例如第一定位信息可包括物理小区标识(physical cell identity，physCell Id)、小区全局标识(cell Global Id)中的传输点标识(transmission point identity,Trp ID)一种或多种标识。
终端获得第一定位测量结果之后，可将包括第一定位测量结果的第一定位信息发送给服务基站。在一些实施例中，终端可通过RRC信令将第一定位信息发送给服务基站。由于RRC信令的上报周期(通常为160ms)小于LPP信令的上报周期(通常为250ms)，所以本申请实施例在终端和服务基站之间交互的第一定位信息通过RRC信令，有助于缩短上报终端的定位信息的周期。
S502、服务基站将第一定位信息发送给LMF，LMF接收该第一定位信息，该第一定位信息承载于NRPPa信令。
服务基站接收第一定位信息之后，将第一定位信息发送给LMF，以便LMF根据第一定位信息计算终端的位置。示例性的，服务基站可向LMF发送第二消息，该第二消息携带第一定位信息，该第二消息是NRPPa消息。也就是，服务基站通过NRPPa信令将第一定位信息发送给LMF。由于NRPPa信令对上报周期的时长不作限制，且RRC信令的上报周期(通常为160ms)小于LPP信令的上报周期(通常为250ms)，所以在终端和LMF之间交互的第一定位信息先后通过RRC信令和NRPPa信令承载，可缩短上报终端的定位信息的周期，也就缩短上报终端位置的周期。
S503、LMF根据第一定位信息确定终端的位置。
LMF可以基于第一定位信息，以及其他可能需要的定位信息，利用定位计算方法可以计算终端的位置。这里定位计算方法可以参见LMF定位的原理，不再赘述。应理解，LMF定位所需要的其他定位信息，即除了第一定位信息之外的定位信息可参考现有技术，这里不再赘述。
LMF对终端进行定位之前可以收集终端的定位信息，示例性的，请参见图6，为本申请实施例提供的定位方法的一种流程示意图。在S501之前，该方法还可执行如下步骤：
S601、LMF向服务基站发送第三消息，服务基站接收该第三消息，该第三消息包括第一指示信息和/或第二指示信息，该第三消息承载于NRPPa信令，其中，第一指示信息用于指示服务基站上报第一定位信息，第二指示信息用于指示服务基站向终端请求第一定位信息。
应理解，第三消息只是名称的一个示例，本申请实施例对第三消息的具体名称不作限制，例如第三消息也可称为位置信息请求消息。需要说明的是，第三消息可以是新定义的NRPPa消息，也可以是已有的NRPPa消息。如果第三消息是已有的NRPPa消息，第一指示信息或第二指示信息可以是该NRPPa消息新增加的字段；或者第一指示信息或第二指示信息可以复用该NRPPa消息已定义的字段。同理，如果第三消息是已有的NRPPa消息，第一指示信息或第二指示信息可以是该NRPPa消息新增加的字段；或者第一指示信息或第二指示信息可以复用该NRPPa消息已定义的字段。
作为一种示例，LMF可通过NRPPa信令向服务基站发送第三消息，以尽量减小终端定位所需的时长，缩短终端上报定位信息的周期。当然，第三消息除了以承载于NRPPa信令的方式发送给服务基站外，也可以是通过其它形式发送，本申请实施例对第三消息的发送方式不做具体限制。例如第三消息可承载于RRC信令，也可承载于LPP信令。
第一指示信息用于指示网络设备上报终端的第一定位信息，第一指示信息包括的信息不同，网络设备上报的第一定位信息也有所不同。下面介绍第一指示信息包括的几种可能的信息，以及相应的第一定位信息。
1)、第一指示信息可包括邻区索引列表，用于指示服务基站上报与该邻区索引列表相关的第一定位信息，以尽量避免定位失败。
2)、第一指示信息可包括定位方法，以用于指示服务基站上报与该定位方法对应的第一定位信息，以尽量避免服务基站上报的第一定位信息不能用于LMF支持的定位计算方法。示例性的，该定位方法可包括OTDOA定位方法，第一定位信息可包括用于OTDOA定位的RSTD值；又一示例性的，该定位方法包括DL-AOD定位方法，第一定位信息可包括用于DL-AOD定位的RSRP值，这里不再一一列举。应理解，第一指示信息可包括多种定位方法，第一定位信息可包括这多种定位方法中的一种定位方法或者多种定位方法。例如服务基站可从第一指示信息指示的多种定位方法选择一种定位方法，上报与所选择的定位方法对应的第一定位信息。或者，服务基站可从第一指示信息指示的多种定位方法选择至少两种定位方法，上报与这至少两种定位方法对应的第一定位信息。或者服务基站可上报与第一指示信息指示的多种定位方法分别对应的第一定位信息。当服务基站上报的与多种定位方法对应的第一定位信息，LMF可选择其中的一种定位方法对应的第一定位信息计算终端的位置；或者，LMF也可以其中的多种定位方法分别对应的第一定位信息计算终端的位置，即结合多种定位方法实现终端的定位。
需要说明的是，第一定位信息可包括定位方法，也可以不包括定位方法。
3)、第一指示信息可包括第一定位信息的上报方式，例如周期性上报或者触发上报。基于触发条件上报第一定位信息，可满足终端的实时定位的需求。周期性上报第一定位信息，不需要LMF、服务基站和终端之间更多次的交互，就能实现终端的多次定位。应理解，如果第一指示信息包括的上报方式为周期性上报，那么第一指示信息应携带上报周期；或者，该上报周期可以是缺省的，例如上报周期是预定义的，或者协议规定的。
应理解，如果第一指示信息指示的上报方式为周期性上报，那么服务基站在接收到第 三消息之后，按照上报周期向LMF多次上报第一定位信息；如果第一指示信息指示的上报方式为触发上报，那么服务基站接收到第三消息，向LMF上报一次第一定位信息。
另外，服务基站可主动向终端请求第一定位信息，例如第三消息包括第一指示信息，这种情况下，服务基站也可以向终端请求第一定位信息。服务基站也可主动向LMF上报第一定位信息，例如第三消息包括第二指示信息，服务基站向终端请求第一定位信息之后，可主动向LMF上报该第一定位信息。
4)、第一指示信息可包括信息采集时长，用于指示服务基站上报终端在该信息采集时长内的第一定位信息，有助于确定终端的运动轨迹。应理解，终端在信息采集时长内周期性上报测量结果。如果第一指示信息包括信息采集时长，那么默认第一指示信息指示服务基站周期上报终端的第一定位信息。
需要说明的是，在一些实施例中，第一指示信息可包括如上4种信息的任意多种的组合。示例性的，第一指示信息可包括邻区索引列表和定位方法，也可以包括邻区索引列表和定位方法以及上报方式，也可以包括邻区索引列表和定位方法以及上报方式和信息采集时长，这里不再一一列举。
应理解，LMF向服务基站请求终端的第一定位信息之前，可与终端交互定位辅助信息，例如LMF需要告知终端测量哪些小区。由于不同的小区的PRS的配置不同，因此，LMF还需要告诉终端每个小区的PRS的配置。
具体的，S601a、LMF和终端交互定位辅助信息。
LMF和终端交互定位辅助信息类似OTDOA定位流程中终端与LMF通过LPP信息交互信息的流程，也就是LMF获取终端的定位能力，比如，LMF向终端请求定位能力，LMF通过LPP请求能力(request capability)过程请求终端的定位能力，终端通过LPP提供能力(provide capability)将定位能力信息上报给LMF。所述定位能力信息可包括终端支持的定位方法，终端支持的定位方法对应的测量能力等。终端向LMF请求定位辅助信息，LMF通过LPP提供辅助数据(provide assistance data)向终端发送辅助信息等，这里不再一一赘述。定位辅助信息可包括终端需要测量的小区的小区索引，例如邻区的小区索引和/或参考小区的小区索引，还可以包括PRS配置等。
S602、服务基站向终端发送第四消息，终端接收该第四消息，该第四消息用于请求第一定位信息，该第四消息承载于RRC信令。
服务基站接收到第三消息之后，如果第三消息携带第二指示信息，服务基站可向终端发送第四消息。作为一种示例，服务基站可通过RRC信令向终端发送第四消息。
与第三消息类似，第四消息也可包括一些指示信息，例如第四消息可包括用于指示定位方法的第三指示信息，用于请求与该第三指示信息所指示的定位方法相关的定位信息。终端向服务基站发送与第三指示信息对应的第一定位信息。例如，第三指示信息指示的定位方法为OTDOA定位方法，第一定位信息包括RSTD值和/或RSTD质量；又例如，第三指示信息指示的定位方法为DL-AOD定位方法，那么第一定位信息包括各PRS发送波束对应的RSRP值等。
又例如，第四消息可包括用于指示上报方式的第四指示信息。终端根据该第四指示信息确定如何向服务基站上报第一定位信息。例如第四指示信息指示的上报方式为周期上报，终端接收第四消息后，按照上报周期向服务基站多次发送第一定位信息。例如第四指示信息指示的上报方式为触发上报，终端接收第四消息后向服务基站发送一次第一定位信息。
在又一些实施例中，第四消息可包括第三指示信息和第四指示信息，具体参见上述第三消息，以及第一指示信息和第二指示信息的介绍，这里不再赘述。
S603、终端确定第一定位信息。
应理解，终端接收第四消息后，例如可对各个基站发送的PRS进行测量，以获得定位测量结果。之后，终端根据第四消息包括的第三指示信息和/或第四指示信息，从定位测量结果确定第一定位信息，并向服务基站发送该第一定位信息。
应理解，在S603之前，终端还应执行测量步骤，即对服务基站发送的下行参考信号进行测量，或者对服务基站和至少一个邻区基站发送的下行参考信息进行测量。
示例性的，S603a、终端对各个基站发送的PRS进行测量。
作为S603a的一种可替换的方案，S603b、终端对各个基站发送的CSI-RS进行测量。由于终端执行S603a和S603b中的一个步骤即可，所以在图6中以虚线示意S603b，即是可选的步骤。
在本申请实施例中，通过NRPPa信令承载终端和LMC之间交互的信息，例如定位测量结果、位置信息请求消息等，可缩短终端的定位周期，以适用需要频繁获知终端的位置的场景。
请参见图7，为本申请实施例提供的上下行定位方法的流程图。在下文的介绍过程中，以该方法应用于图2-图4所示的通信***为例。另外，该方法可由三个通信装置执行，这三个通信装置例如为第一通信装置、第二通信装置和第三通信装置。为了便于介绍，在下文中，以该方法由网络设备、终端和定位管理设备执行为例，也就是，以第一通信装置是网络设备、第二通信装置是终端，第三通信装置是定位管理设备为例。需要说明的是，本申请实施例只是以通过图2-图4的通信***为例，并不限制于这种场景。应理解，在上下行定位的场景中，还涉及到各个基站对终端发送的上行参考信号的测量，所以该方法可能涉及更多个网络设备。例如该方法涉及第一网络设备，至少一个第二网络设备等。应理解，当前终端当前接入的网络设备有一个(该网络设备可称为服务基站)，为了便于描述，下文中将第一网络设备称为服务基站，相对而言，第二接入网设备可称为邻区基站。在本文中，定位管理设备可以是LMF网元，应理解，在未来通信如6G中，定位管理设备仍可以是LMF网元，或有其它的名称，本申请实施例不做限定。
具体的，本申请实施例提供的定位方法的具体流程描述如下：
S701、终端向服务基站发送第一消息，服务基站接收该第一消息，其中，该第一消息包括第二定位信息，该第二定位信息承载于RRC信令。
S702、服务基站向LMF发送第二消息，LMF接收该第二消息，其中，该第二消息承载于NRPPa信令，该第二消息包括第三定位信息，该第三定位信息包括第二定位信息，以及服务基站测量第二参考信号和第三参考新获得的第三测量结果。
与前述图5和图6的流程类似，在终端和LMF之间交互的第三定位信息通过NRPPa信令承载，相较于通过LPP信令承载，可缩短定位信息的上报周期。
应理解，第二定位信息和第三定位信息与前述第一定位信息类似，第二定位信息是定位终端所需要的信息中的部分信息，为了完成终端的定位过程，所需要的其他定位信息，可参考现有技术，这里不再赘述。与第一定位信息的不同之处在于，在本申请实施例中，第二定位信息包括终端测量第二参考信号和第三参考信号获得的第二测量结果。第三定位信息包括服务基站测量第二参考信号和第三参考信号获得的第三测量结果。应理解，第二 参考信号为下行参考信号，可以为PRS或CSI-RS，第三参考信号可以是上行参考信号，可以为SRS。
在一些实施例中，第二测量结果携带的信息元素(在下文中简称为信元)可包括终端内部的接收-发送时间差(UE Rx-Tx time difference)，可用于Multi-RTT定位。第三测量结果携带的信息元素(在下文中简称为信元)可包括基站内部的接收-发送时间差(gNB Rx-Tx time difference)，可用于Multi-RTT定位。
第三定位信息与第一定位信息类似，除了包括第二定位信号和第二测量结果之外，还可以包括定位方法，例如Multi-RTT定位。应理解，第三定位信息也可以包括多种定位方法，例如第三定位信息Multi-RTT定位和其他可能的定位方法(例如OTDOA定位方法、DL-AOA定位方法和DL-AOD定位方法中的一种或多种)，以用于联合定位。应理解，如果第三定位信息包括的定位方法不止一种，那么第三定位信息应包括与各种定位方法对应的测量结果，例如可包括RSRP值、RSTD值以及到达角中的一种或多种。
同样的，第三定位信息与第一定位信息类似，也可以包括误差信息、邻区索引列表，具体可参考前述对第一定位信息的相关描述，这里不再赘述。
终端获得第二定位测量结果之后，可将包括第二定位测量结果的第二定位信息发送给服务基站。在一些实施例中，终端可通过RRC信令将第二定位信息发送给服务基站。由于RRC信令的上报周期(通常为160ms)小于LPP信令的上报周期(通常为250ms)，所以本申请实施例在终端和服务基站之间交互的第一定位信息通过RRC信令，有助于缩短上报终端的定位信息的周期。
服务基站接收第二定位信息之后，将包括第二定位信息和第三测量结果的第三定位信息发送给LMF，以便LMF根据第三定位信息计算终端的位置。
应理解，在S701之前，LMF对终端进行定位之前收集终端的定位信息，该方法还可执行如下步骤：
S7011、LMF和终端交互定位辅助信息。
具体的，701a与S601a相同，这里不再赘述。
S7012、LMF向服务基站发送第三消息，服务基站接收该第三消息，该第三消息包括第三指示信息和/或第四指示信息，该第三消息承载于NRPPa信令，其中，第三指示信息用于指示服务基站上报第三定位信息，第四指示信息用于指示服务基站向终端请求第二定位信息。
第三指示信息与前述第一指示信息类似，具体实现可参考前述第一指示信息的实现，这里不再赘述。第三指示信息与前述第一指示信息的不同之处在于，第三指示信息包括的定位方法可为Multi-RTT定位。同理，第四指示信息与前述第二指示信息类似，具体实现可参考前述第一指示信息的实现，这里不再赘述。
应理解，第二定位信息与第四指示信息对应，第三定位信息与第三指示信息对应，例如，第三指示信息包括的定位方法可为Multi-RTT定位，第三定位信息可包括第二测量结果和第三测量结果。具体可参考前述第一定位信息和第一指示信息的对应，或者第一定位信息与第二指示信息的对应。
应理解，LMF向服务基站请求终端的第二定位信息之前，可与终端交互定位辅助信息，例如LMF需要告知终端测量哪些小区。由于不同的小区的PRS的配置不同，因此，LMF还需要告诉终端每个小区的PRS的配置。
S7013、服务基站向终端发送第四消息，终端接收该第四消息，该第四消息用于请求第二定位信息，该第四消息承载于RRC信令。
具体的，S7013与S602相同，这里不再赘述。
S7014、终端对第二参考信号和第三参考信号进行测量。
应理解，终端接收第四消息后，例如可对各个基站发送的第二参考信号以及对向各个基站发送的第三参考信号进行测量，获得第二测量结果。之后，终端根据第三消息包括的第三指示信息和/或第四指示信息，向服务基站发送包括第二测量结果的第二定位信息。
S703、LMF根据第三定位信息确定终端的位置。
LMF可以基于第三定位信息，以及其他可能需要的定位信息，利用定位计算方法可以计算终端的位置。例如LMF可根据第三定位信息和至少一个邻区基站对第二参考信号和第三参考信号测量获得的第四测量结果确定终端的位置。
在一种可能的实现方式中，至少一个邻区基站可以将第四测量结果发送给LMF，也可以将第四测量结果发送给服务基站，由服务基站再将第四测量结果发送给LMF。下面分别以具体的示例分别介绍。
请参见图8，为本申请实施例提供的定位方法的一种示例的流程图。该定位流程以至少一个邻区基站向LMF发送第四测量结果为例。该流程包括：
S801、终端与LMF交互定位辅助信息。
具体实现方法同图7中的S7011，这里不再赘述。
S802、LMF向服务基站发送第三消息，该第三消息承载于NRPPa信令。
具体实现方法同图7中的S7012，这里不再赘述。
S803、服务基站向终端发送第四消息，该第四消息承载于RRC信令。
该第四消息携带的信元可包括定位方法和上报方法。具体实现方法同图7中的S7013，这里不再赘述。
S804、服务基站为终端配置SRS的时频资源，并指示终端按照服务基站配置的时频资源发送SRS。
示例性的，服务基站可通过RRC信令通知终端，服务基站为终端所配置的SRS的时频资源，终端按照服务基站配置的时频资源发送SRS。
S805、服务基站向LMF发送定位响应消息，该定位响应消息用于指示服务基站为终端配置的SRS资源。
示例性的，服务基站可通过NRPPa信令向LMF发送定位响应消息，以进一步降低定位终端过程中的时延。
S806、LMF通过NRPPa信令向至少一个邻区基站发送SRS测量请求。
应理解，本申请实施例用于上下行定位，需要测量基站。在本申请实施例LMF通过NRPPa信令向至少一个邻区基站发送SRS测量请求，可进一步降低定位终端过程中的时延。
S807、终端对各基站发送的PRS进行测量。
需要说明的是，本申请实施例对S806和S807的执行顺序不作限制。
S808、终端通过RRC信令将第二定位信息发送给服务基站。
具体参考图7中S701的相关实施例的介绍，这里不再赘述。
S809、服务基站通过NRPPa信令将第三定位信息发送给LMF。
S810、至少一个邻区基站将第四测量结果发送给至LMF，该第四测量结果承载于 NRPPa信令。
应理解，至少一个邻区基站可通过NRPPa信令将第二定位信息发送给至LMF，以尽量缩短定位终端的周期。需要说明的是，本申请实施例对S809和S810的执行顺序不作限制。
S811、LMF根据第三定位信息和第四测量结果计算终端的位置。
应理解，如果不存在对邻区基站的测量，那么LMF根据第三定位信息计算终端的位置。
在另一实施例中，作为S810的一种可替换的方案，S812、至少一个邻区基站可通过Xn接口将第四测量结果发送给服务基站。这种情况下，S809中，服务基站向LMF发送的第三定位信息包括第四测量结果。且S806中，LMF向至少一个邻区基站发送的SRS测量请求包括邻区索引列表，以告知至少一个第二网络设备需要向哪个第一网络设备上报第三测量结果。应理解，S812是可选的方案，因此在图8中以虚线进行示意。
以上各实施例可以相互结合以实现不同的技术效果。
上述本申请提供的实施例中，从终端、网络设备和定位管理设备之间交互的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，终端、网络设备和定位管理设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
