Description

一种定位方法、装置及系统 技术领域
本申请涉及通信领域，尤其涉及一种定位方法、装置及系统。
背景技术
随着无线通信技术的发展，基于位置的服务成为最有前途的业务之一。无论是在室内还是室外环境下，快速准确地获得终端设备的位置信息和提供位置服务的需求变得日益迫切。与室外环境相比，在室内环境中感测位置信息更具挑战性。目前常用的室内定位技术可以包括到达时间差(time difference of arrival，TDOA)定位技术和到达角(angle of arrival，AOA)定位技术等。
以TDOA定位技术中的上行链路(uplink，UL)TDOA为例，协议(TS 36.305 8.5.3)中定义了UL-TDOA定位终端设备的流程，包括：演进的服务定位中心(Evolved serving mobile location center，E-SMLC)向演进基站(evolved node B，eNB)发送定位请求，请求eNB为终端设备配置探测参考信号(sounding reference signal，SRS)资源，eNB接收到定位请求后配置终端设备的SRS资源，终端设备可以通过SRS资源广播SRS。LMU可以测量终端设备广播的SRS，并将测量结果返回E-SMLC，由E-SMLC计算终端设备广播的SRS到达各个LMU的时间差，从而根据计算结果定位终端设备。
在上述上行链路定位的信令流程中，是由核心网侧(例如，E-SMLC)确定终端设备的位置，无法满足上行链路定位过程中基于终端设备定位(由终端设备自行计算自身位置)的需求。

具体实施方式
为了下述各实施例的描述清楚简洁，首先给出相关概念或技术的简要介绍：
UL-TDOA：在本申请实施例中是指终端设备(例如，用户设备(user equipment，UE))发送(发射)的参考信号(reference signal，RS)分别到达两个网络设备(例如，基站)的时间差。其中，参考信号即导频信号，是由发射端发送给接收端用于信道估计或信道探测的一种已知信号。例如，参考信号可以是探测参考信号
(sounding reference signal，SRS)。UL-TDOA可以是根据参考信号到达两个网络设备的两个上行到达相对时间(uplink relative time of arrival，UL-RTOA)确定的。
示例性的，参考图1，假设UE发送的参考信号传输至基站1的UL-RTOA为T1，UE发送的参考信号传输至基站2的UL-RTOA为T2，T1与T2之间的时间差即为UL-TDOA。
上行到达角(uplink angle of arrival，UL-AOA)：在本申请实施例中指终端设备发送的参考信号到达网络设备时与某一方向(如：水平面或水平面的法线)之间的夹角。
示例性的，参考图2，UE发送的参考信号的上行到达角可以是UE发送的参考信号到达基站时与正北方向的夹角α。可以根据UE所发射的参考信号的上行到达角确定一条从UE到基站的直线，该直线与正北方向的夹角为α。本申请实施例中将这条直线称为方向线。
通常，参考信号是以电磁波形式传递，电磁波在空间传播过程中可能遇到各种各样的障碍物而产生反射、散射等，因此，接收端接收的参考信号是多个传播路径上的信号的叠加。其中，电磁波在空间传播过程中的传播路径可以是反射径或视距径。如图3所示，参考信号的视距径表示参考信号在传播过程中没有遇到障碍物直接到达接收端的传播路径(直线传播路径)，参考信号的反射径表示参考信号在传播过程中遇到障碍物发生反射后到达接收端的传播路径(折线传播路径)，参考信号的反射径可以包括多条(例如，图3中的参考信号的反射经1和参考信号的反射经2)。本申请实施例中参考信号的上行到达角可以是参考信号的某个反射径到达接收端时与某个方向(例如，正北方向)的夹角，也可以是参考信号的视距径到达接收端时与某个方向的夹角，本申请不做限定。
RRC状态：以新无线(new radio，NR)系统为例，终端设备的无线资源控制状态包括连接态(RRC_CONNECTED)、去激活态(RRC_INACTIVE)和空闲态(RRC_IDLE)。下面分别对这三种状态进行说明。
(1)当终端设备处于连接态时，该终端设备与接入网设备以及核心网设备都已建立链路，当有数据到达网络时，核心网设备和接入网设备可以直接将数据传送至该终端设备。
(2)当终端设备处于去激活态时，说明该终端设备之前和接入网设备以及核心网设备建立过链路，但是该终端设备与接入网设备之间的链路被释放了。虽然链路被释放了，但是接入网设备需要保存终端设备的上下文，当有数据需要传输时，接入网设备可以根据终端设备的上下文快速恢复被释放的这段链路。
(3)当终端设备处于空闲态时，该终端设备与接入网设备和核心网设备之间都没有链路，当有数据需要传输时，需要建立终端设备到接入网设备及核心网设备的链路。
基于UE能力(UE-based)的定位：是指UE获取上行链路定位测量结果和参与定位的接入网设备的位置信息后，自行计算出自身位置的定位方式。
目前，第三代合作伙伴计划(3rd generation partnership project，3GPP)NR可以支持的UE-based定位技术包括下行到达定时差(downlink time difference of arrival，DL-TDOA)定位和下行出发角(downlink angle of departure，DL-AOD)定位。DL-TDOA定位和DL-AOD定位都是由终端设备测量网络设备发送的参考信号，以得到定位测量结果。但除了上述两种UE-based定位技术之外，理论上还可以支持更多UE-based的定位技术。
本申请实施例提出了一种定位方法，通过网络设备或者定位管理设备辅助UE获取上行链路定位测量结果，能够实现UE-based UL-AOA/UL-TDOA定位。
本申请实施例提供的定位方法可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、第五代(5th generation，5G)系统或NR等，其中，5G移动通信系统包括非独立组网(non-standalone，NSA)的5G移动通信系统或独立组网(standalone，SA)的5G移动通信系统。本申请提供的技术方案还可以应用于未来的通信系统，如第六代移动通信系统。通信系统还可以是陆上公用移动通信网(Public Land Mobile Network，PLMN)网络、设备到设备(device-to-device，D2D)通信系统、机器到机器(machine to machine，M2M)通信系统、物联网(Internet of Things，IoT)通信系统或者其他通信系统，本申请不做限定。
具体的，本申请实施例提供的定位方法可以应用于上述各种通信系统中的上行链路定位的场景中。例如，应用于UL-AOA/UL-TDOA定位场景中。在上述上行链路定位的场景中，UE可以获取上行链路定位测量结果，基于UE能力(UE-based)自行计算出自身位置。
如图4所示，为本申请实施例提供的一种定位系统示意图，该定位系统涉及的网元包括终端设备、参与定位的接入网设备、接入及移动性管理功能网元和定位管理设 备。其中，参与定位的接入网设备可以包括为终端设备服务的接入网设备(可以简称为服务接入网设备)和/或至少一个邻区(邻居/相邻)接入网设备。图4所示的定位系统又可以称为基于5G核心网的定位架构。
终端设备与服务接入网设备可以通过NR蜂窝链路(Uu链路)进行通信，服务接入网设备和邻区接入网设备之间可以通过Xn接口连接，服务接入网设备、邻区接入网设备与接入及移动性管理功能网元之间可以通过下一代控制面(next genaeration Control plane，NG-C)接口进行通信，接入及移动性管理功能网元与定位管理设备之间通过NLs接口进行通信。其中：
1、终端设备用于向参与定位的接入网设备发送参考信号，以及接收上行链路测量结果和参与定位的接入网设备的位置信息，以确定自身的位置。
2、参与定位的接入网设备用于测量终端设备发送的参考信号，并可以将测量结果发送给定位管理设备或者直接发送给终端设备。参与定位的接入网设备也可以作为中间设备，用于转发定位管理设备和终端设备之间的信息。
3、接入及移动性管理功能(access and mobility management function，AMF)网元，主要用于移动性管理和接入管理等，可以用于实现例如，合法监听、或接入授权(或鉴权)等功能。本申请实施例中，AMF可以作为中间设备，用于转发定位管理设备和参与定位的接入网设备之间的信息，或者转发定位管理设备和终端设备之间的信息。
4、定位管理设备，负责支持UE的不同类型的位置服务，包括对UE定位和向UE传递辅助数据等。下面以定位管理设备为LMF网元为例进行说明。
LMF网元的控制面和用户面分别是增强服务移动位置中心(enhanced serving mobile location center，E-SMLC)和安全用户面定位平台(secure user plane location location platform，SLP)。具体地，LMF网元可以与上述参与定位的接入网设备和终端设备之间进行如下的信息交互：
(1)LMF网元可以与参与定位的接入网设备之间通过某些特定的定位协议，例如NR定位协议(NR positioning protocol annex，NRPPa)消息，进行信息交互。例如，LMF网元与参与定位的接入网设备之间可以通过NRPPa消息传输SRS配置信息、小区定时、小区位置信息等。
(2)LMF网元与终端设备之间可以通过LTE定位协议(LTE positioning protocol，LPP)消息进行UE能力信息、辅助信息、测量结果等信息的传输。
应理解，上述LMF网元和参与定位的接入网设备之间的信息传输、LMF网元和终端设备之间的信息传输，均可以是通过中间设备进行转发的。以UE向LMF网元发送能力信息为例，UE可以先将能力信息发送给参与定位的接入网设备(例如，服务接入网设备)，服务接入网设备和AMF网元对该能力信息进行转发，从而使得LMF网元接收到UE发送的能力信息。示例性的，UE可以向LMF网元发送LPP消息，LPP消息可以是通过LPP协议数据单元(protocol data unit，PDU)传输的，具体可以包括三个步骤：(1)UE将LPP PDU包含在第一消息(例如UL NAS Transport消息)的负载(payload)容器中，然后，UE在第二消息(例如RRC UL Information Transfer消息)中将第一消息发送给服务接入网设备；(2)服务接入网设备通过第三消息(例如NGAP Uplink NAS Transport消息)将第一消息转发给AMF网元；(3)AMF网元 从第一消息中获取LPP PDU将其包含在N1消息容器中发送给LMF网元。
本申请实施例中的终端设备可以称为终端，可以是一种具有无线收发功能的设备，其可以部署在陆地上，包括室内或室外、手持、穿戴设备、汽车或车载设备；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)。终端设备可以是UE，UE包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。示例性地，UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
本申请实施例中，实现终端的功能的装置可以是终端，也可以是支持终端实现该功能的装置，例如芯片、电路或者其它装置。本申请实施例中，以实现终端的功能的装置是终端设备为例，描述本申请实施例提供的技术方案。
本申请中的定位管理设备可以是位置管理功能(location management function，LMF)网元、LMC定位管理单元(location management unit，LMU)或者其他具有定位管理功能的网络设备。本申请以定位管理设备是LMF作为示例，但本申请对定位管理设备不做具体限定。
本申请中的参与定位的接入网设备可以是Ng-eNB、gNB(包括(服务下一代基站serving next generation Node B，Serving gNB)，和/或，邻区下一代基站(neighbor next generation Node B，Neighbor gNB))或传输接收点(transmission reception point，TRP)，还可以是第三代合作伙伴计划(3rd generation partnership project，3GPP)所定义的基站。例如，LTE系统中的基站设备，即演进型节点B(evolved NodeB，eNB/eNodeB)等。此外，当eNB接入NR的核心网或者下一代核心网(Next Genaeration Core,NGC)或者5G核心网(5th Generation Core Network，5GC)时，eNB也可以称为eLTE eNB。具体地，eLTE eNB是在eNB的基础上演进的LTE基站设备，可以直接连接5G CN，eLTE eNB也属于NR中的基站设备。或者，接入网设备还可以是无线端点(wireless terminal，WT)。例如接入点(access point，AP)或者接入控制器(access controller，AC)，或者其他具有与用户设备、及核心网有通信能力的网络设备。例如，中继设备、车载设备、智能穿戴设备等。本申请对接入网设备的类型不做限定。
应理解，上述图4仅为定位通信系统的示意图，定位通信系统中还可以包括其它未示出的设备。本申请实施例对定位通信系统中包括的终端设备、接入网设备的数量不做限定。
本申请也不排除在现有或未来的协议中定义其他可能的命名来替代上述定位通信系统中各设备的名称，但具有相同或相似的特性。
示例性的，本申请提供的定位方法还可应用于LTE系统中，其中，参与定位的接入网设备可以是eNB，定位管理设备可以是E-SMLC，AMF可以被替换为移动管理实体(mobility management entity，MME)。定位管理设备与参与定位的接入网设备之间通信的协议为LPPa。
在对本申请实施例中的技术方案进行具体描述之前，首先做出以下几点说明：
1、在本申请的描述中，除非另有说明，“至少一个”是指一个或多个，“多个”是指两个或多于两个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
2、在本申请的描述中，各个网元以及各个网元之间的接口名字只是一个示例，具体实现中各个网元以及各个网元之间的接口名字可能为其他，本申请实施例对此不作具体限定。

4、在本申请中，“指示”可以包括直接指示和间接指示，也可以包括显式指示和隐式指示。将某一信息(如下文所述的能力信息)所指示的信息称为待指示信息，则具体实现过程中，对待指示信息进行指示的方式可以有很多种，例如但不限于，可以直接指示待指示信息，如指示待指示信息本身或者该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息，其中该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。
5、在下文示出的实施例中，各术语及英文缩略语，如媒体接入控制控制元素(media access control-control element，MAC CE)、无线资源控制(radio resource control，RRC)等，均为方便描述而给出的示例性举例，不应对本申请构成任何限定。本申请并不排除在已有或未来的协议中定义其它能够实现相同或相似功能的术语的可能。
下面将结合本申请实施例中的附图，对本申请实施例提供的定位方法进行具体介绍。
如图5所示，本申请实施例提供一种定位方法，包括：
501、定位管理设备向终端设备发送能力请求信息，能力请求信息用于指示终端设备上报其能力信息。
示例性的，定位管理设备可以通过第一LPP消息向终端设备发送能力请求(RequestCapabilities)消息，RequestCapabilities消息中可以携带能力请求信元。能力请求信息可以是指RequestCapabilities消息。
502、终端设备向定位管理设备发送能力信息，能力信息用于指示终端设备是否支持基于终端设备的上行链路定位。
终端设备接收到定位管理设备发送的能力请求信息后，可以向定位管理设备发送能力信息。或者，终端设备可以直接发送能力信息，即可以不执行步骤501，直接执行步骤502。
示例性的，终端设备可以通过第二LPP消息向定位管理设备发送提供能力(ProvideCapabilities)消息，ProvideCapabilities消息中可以携带提供能力信元。能力信息可以是指ProvideCapabilities消息。其中，ProvideCapabilities消息中的提供能力信元可以包括UL AOA提供能力信元、UL TDOA提供能力信元或上行链路定位提供 能力信元中的至少一种。定位管理设备接收到终端设备发送的能力信息后，可以根据终端设备的能力信息确定终端设备是否支持基于终端设备的上行链路定位，上行链路定位包括UL AOA和/或UL TDOA。
示例性的，以ProvideCapabilities消息中的提供能力信元是UL AOA提供能力信元为例，当UL AOA提供能力信元的比特值为1时，可以表示终端设备支持基于终端设备的UL AOA定位，当UL AOA提供能力信元的比特值为0时，可以表示终端设备不支持基于终端设备的UL AOA定位。
503、终端设备向定位管理设备发送请求辅助数据信息(第二请求辅助数据信息)，第二请求辅助数据信息用于请求参与定位的接入网设备的位置信息。
示例性的，终端设备可以通过第三LPP消息向定位管理设备发送第二请求辅助数据信息(RequestAssistanceData)消息。第二请求辅助数据信息可以是指第二RequestAssistanceData消息。
定位管理设备接收到终端设备发送的第二请求辅助数据信息后，可以向终端设备发送提供辅助数据信息(第二提供辅助数据信息)，第二提供辅助数据信息中包括参与定位的接入网设备的位置信息。
504、终端设备接收定位管理设备发送的第二提供辅助数据信息，第二提供辅助数据信息包括参与定位的接入网设备的位置信息。
示例性的，终端设备可以接收定位管理设备发送的第四LPP消息，第四LPP消息中可以包括第二提供辅助数据(ProvideAssistanceData)消息。第二提供辅助数据信息可以是指第二ProvideAssistanceData消息。
需要说明的是，本实施例中的步骤503和步骤504是可选的步骤，可以执行步骤503和步骤504，即定位管理设备可以基于第二请求辅助数据信息发送第二提供辅助数据信息；或者，可以仅执行步骤504，即定位管理设备可以基于能力信息发送第二提供辅助数据信息，或者，定位管理设备可以直接发送第二提供辅助数据信息；或者，也可以不执行步骤503和步骤504，以节省信令开销，本实施例对此不作具体限定。
505、定位管理设备向服务接入网设备发送第一NRPPa消息，该第一NRPPa消息用于触发服务接入网设备为终端设备分配SRS资源。
服务接入网设备接收到定位管理设备发送的第一NRPPa消息后，可以执行步骤506。
506、服务接入网设备为终端设备分配SRS资源。
服务接入网设备接收到第一NRPPa消息后，可以根据现有可用资源为终端设备分配SRS资源。
507、服务接入网设备向终端设备发送SRS资源配置信息。
示例性的，服务接入网设备可以通过RRC信令或MAC CE向终端设备发送SRS资源配置信息，即SRS资源配置信息可以携带在RRC信令或MAC CE中。终端设备接收到RRC信令或MAC CE后，可以从中解析出SRS资源配置信息。
终端设备接收到SRS资源配置信息后，终端设备可以根据该分配的SRS资源周期性地发送SRS(广播SRS)，为上行链路定位提供条件，使参与定位的接入网设备可以测量终端设备发送的SRS。
508、服务接入网设备向定位管理设备发送第二NRPPa消息，该第二NRPPa消息包括终端设备的SRS资源配置信息。
定位管理设备接收到服务接入网设备发送的第二NRPPa消息后，可以获知服务接入网设备已成功为终端设备配置了相应的SRS资源。
而后，定位管理设备可以确定参与定位的接入网设备，并从参与定位的接入网设备处获取上行链路定位测量结果。其中，参与定位的接入网设备可以包括服务接入网设备和/或至少一个邻区接入网设备。例如，参与定位的接入网设备可以仅包括服务接入网设备。或者，参与定位的接入网设备可以包括服务接入网设备和至少一个邻区接入网设备。
下面以终端设备支持的上行链路定位为UL TDOA定位为例，对定位管理设备获取上行链路定位测量结果的过程进行说明：
若参与定位的接入网设备仅包括服务接入网设备，定位管理设备可以指示服务接入网设备对终端设备通过不同的上行资源发送的多个(至少三个)不同的参考信号(例如，SRS)进行测量，服务接入网设备可以获得至少三个不同的SRS对应的至少三个到达时间(例如，UL-RTOA)，根据该至少三个到达时间可以获得至少两个到达时间差(例如，UL-TDOA)，并将测量所得的至少两个到达时间差反馈给定位管理设备。定位管理设备获取到的上行链路定位测量结果可以包括至少两个到达时间差。
或者，定位管理设备可以指示服务接入网设备通过至少三个不同的天线端口对终端设备发送的同一个SRS进行测量，服务接入网设备可以获得至少三个天线端口对应的至少三个到达时间，根据该至少三个到达时间可以获得至少两个到达时间差，并将该至少两个到达时间差反馈给定位管理设备。定位管理设备获取到的上行链路定位测量结果可以包括至少两个到达时间差。
若参与定位的接入网设备包括服务接入网设备和至少一个(例如，两个)邻区接入网设备，定位管理设备可以指示服务接入网设备和两个邻区接入网设备分别对终端设备发送的同一个SRS进行测量，并将测量所得的到达时间反馈给定位管理设备。定位管理设备可以根据服务接入网设备和两个邻区接入网设备分别上报的到达时间获取至少两个到达时间差，上行链路定位测量结果可以包括至少两个到达时间差。
若参与定位的接入网设备包括服务接入网设备和一个邻区接入网设备，该服务接入网设备可以通过至少两个不同的天线端口接收终端设备发送的同一个SRS得到两个到达时间，并将该两个到达时间发送给定位管理设备，邻区接入网设备可以接收上述SRS得到一个到达时间，并将该到达时间发送给定位管理设备；或者，邻区接入网设备可以通过至少两个天线端口接收终端设备发送的SRS以获取两个到达时间并将该两个到达时间发送给定位管理设备，服务接入网设备可以接收上述SRS得到一个到达时间，并将该到达时间发送给定位管理设备。这样，定位管理设备可以接收到至少三个到达时间，定位管理设备可以根据至少三个到达时间获取至少两个到达时间差，上行链路测量结果该至少两个到达时间差。
下面以终端设备支持的上行链路定位为UL AOA定位为例，对定位管理设备获取上行链路定位测量结果的过程进行说明：
