随着自动驾驶、智慧城市、物联网等新兴行业的出现，通信技术也越来越多地与这些行业进行融合，这些产业带来了对终端设备定位的需求。当一片区域需要对大量终端设备进行定位时，如园区物料资产盘点，资产追踪等等，当前定位方法针对每个终端设备均需要执行单独的定位流程。核心网设备需要通过大量终端设备所在的无线接入网设备与每个终端设备进行多次信令交互。因此，在同一片区域需要对大量终端进行定位的场景中，核心网设备和无线接入网设备均会有大量的信令负担，对网络资源消耗大。对于终端设备来说，完整的终端设备定位流程涉及到终端设备的测量或者周期的探测参考信号(Sounding Reference Signal，SRS)发送，导致终端设备的能耗较高。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1是现有技术中的一种定位终端设备的无线通信系统100架构的示意性框图。如图1所示，该系统100架构包括，终端设备110，无线接入网设备120，接入和移动管理功能网元130(Access&Mobility Function，AMF)，定位管理中心网元140(Location Management Function，LMF)，网关移动位置中心网元150(Gateway Mobile Location center，GMLC)。
其中，图1中的终端设备可以用于通过无线空口连接到运营商部署的无线接入网设备，继而通过无线接入网设备连接到数据网络；无线接入网设备主要用于实现无线物理层功能、资源调度和无线资源管理、无线接入控制以及移动性管理等功能；接入和移动性管理功能网元主要用于终端设备的设备注册、安全认证、移动性管理和位置管理等，定位管理中心 网元主要用于定位终端设备的位置，该LMF位于核心网内部，该LMF通过AMF与无线接入网设备通信；该网关移动定位中心与外部网络连接，接收外部网络的定位需求或者将定位结果发送到外部网络。
在图1的所示的网络中，各功能单元之间可以通过下一代(Next Generation，NG)接口建立连接实现通信，如：终端设备通过新无线(New Radio，NR)接口与无线接入网设备建立空口连接，用于传输用户面数据和控制面信令；终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接；AMF可以通过NL1接口与LMF建立连接；AMF可以通过NL2接口与GLMC建立连接。
应理解，本申请中的网元之间的接口名称仅是示例性的，网元之间的接口还可以是其他名称，本申请对接口的名称不予限。
应理解，该网络架构还可以包括其他功能单元或功能网元，例如，系统100还可以包括用户面功能网元(User Plane Function，UPF)，数据网络(Data Network，DN)，会话管理功能网元(Session Management Function，SMF)，策略控制功能网元(Policy Control Function，PCF)，应用功能网元(Application Function，AF)。其中，UPF用于对数据流进行转发、QoS控制、计费统计等；DN可对应于多种不同的业务域，例如IP多媒体子系统(IP Multimedia Subsystem，IMS)、互联网Internet、互联网协议电视(Internet Protocol Television，IPTV)、其他运营商业务域等，主要用于为终端设备提供多种数据业务服务，其中可以包含例如服务器、路由器、网关等网络设备；AMF用于进行终端设备的接入和移动性管理，接收PCF提供的UE的移动性策略以及网络选择策略并进行策略执行；SMF用于进行PCF提供的会话以及业务流控制策略并进行策略执行；PCF可以根据AF的请求信息、运营商策略、用户签约信息等生成策略与计费控制规则，控制网络行为，并下发策略与计费控制规则至控制面网元；AF主要提供应用侧对网络侧的需求，包括业务流的服务质量需求、用户设备的移动性需求等。
需要说明的是，图1仅为示例性架构图，除图1中所示功能单元之外，该网络架构还可以包括其他功能单元或功能网元，本申请实施例对此不进行限定。
上述的部分网元可以独立工作，也可以组合在一起实现某些控制功能，如：AMF、SMF和PCF可以组合在一起作为管理设备，用于完成终端设备的接入鉴权、安全加密、位置注册等接入控制和移动性管理功能，以及用户面传输路径的建立、释放和更改等会话管理功能，以及分析一些切片(slice)相关的数据(如拥塞)、终端设备相关的数据的功能，UPF作为网关设备主要完成用户面数据的路由转发等功能，如：负责对终端设备的数据报文过滤、数据传输/转发、速率控制、生成计费信息等。
下面结合图2对现有技术中定位终端设备的方法的过程进行简单描述。
在210中，AMF获取来自不同设备的定位请求，该定位请求用于指示对终端设备进行定位，该定位请求信息可以来源于三个设备，分别是终端设备发送的定位请求，或外部网络发送的定位请求(该外部网络通过GMLC通知AMF)，或AMF本身的定位需求。
在220中，AMF将定位请求发送给定位中心LMF。
在230中，LMF与终端设备或者无线接入网设备进行信令流程的交互。该信令流程可以包括LMF向终端设备或者无线接入网设备定位能力询问，终端设备或者无线接入网设备反馈定位能力，LMF基于定位能力的反馈确定使用的定位方法、向终端设备发送的 测量数据的类型，以及无线接入网设备向终端设备发送的辅助信息，终端设备或者无线接入网设备在测量了数据后将测量数据发送给LMF，LMF基于这些测量数据，计算出终端设备的位置。LMF与终端设备的信令交互基于LTE定位协议(LTE Positioning Protocol，LPP)，LMF与无线接入网设备的信令交互基于新空口定位协议(NR Positioning Protocol A，NRPPa)。
在240中，该LMF将计算出的终端设备的位置信息发送给AMF，然后AMF再将该位置信息返回发送定位请求的设备。
在现有技术中，当需要对一片区域的多个终端设备进行定位时，针对每个终端设备均需要执行单独的前述定位流程，LMF需要通过该多个终端设备所在的无线接入网设备与每个终端设备进行多次信令交互，对网络资源消耗大。其次，对于终端设备来说，完整的终端设备定位流程涉及到终端设备的测量或者向无线接入网设备周期的发送探测参考信号(Sounding Reference Signal，SRS)，导致终端设备的能耗相对较高。
基于上述问题，本申请提供了一种确定终端设备位置的方法和设备，LMF通过已知位置的中继节点，获得多个待测量的终端设备的测量信息，从而确定该多个待测量的终端设备的位置信息。LMF通过已知位置的中继节点获得多个待测量终端设备的测量信息，无需通过无线接入网设备与每个待测量的终端设备进行单独的定位流程，减少了定位多个终端设备流程中的信令开销，其次，待测量的终端设备与中继节点之间的距离较近，在测量的过程中，待测量的终端设备向中继节点发送消息，能够节省待测量的终端设备的发送功耗，从而减少待测量的终端设备的能耗。
下面是本申请提供的一种确定终端设备位置的无线通信系统300的架构的示意性框图。如图3所示，该系统300包括终端设备310，终端设备320，中继节点330，无线接入网设备340，接入和移动管理功能350，定位管理中心网元360，网关移动定位中心370。需要说明的是，该系统300中可以包括多个中继节点，该多个中继节点可以分别对应一个或多个终端设备，本申请对此并不进行限定。
应理解，对于图3所示的系统的其他网元的描述，可以参考图1的相关描述，为了避免重复，此处不再赘述。

在S410中，LMF与中继节点和/或无线接入网设备进行信令交互，确定中继节点的位置信息。
应理解，在本申请的实施例中，LMF确定中继节点的位置信息之前还可以包括LMF确定中继节点。在一种可能的实现方式中，LMF首先确定多个终端设备中具有支持侧链路(sidelink)能力的终端设备，从该具有支持sidelink能力的多个终端设备中选择一个终端设备作为中继节点，其余的具有支持sidelink能力的多个终端设备作为待测量的多个终端设备。
具体地，LMF向多个终端设备发送请求能力(Request Capabilities)消息，该消息用于LMF询问终端设备定位能力，在该请求能力消息中携带询问终端设备是否支持sidelink能力的信息。LMF接收多个终端设备发送的提供能力(Provide Capabilities)消息，该消息用于终端设备或者无线接入网设备反馈定位能力信息，如终端设备支持的定位方法、支持的辅助数据等。如果该多个终端设备中有具有支持sidelink能力的终端设备，该类型的终端设备可以在反馈信息中添加支持sidelink的能力。LMF基于该反馈信息从该类型的终端设备中选择一个终端设备作为中继节点，例如，LMF从该类型的终端设备中随机选择一个作为中继节点。
在另一种可能的实现方式中，LMF向无线接入网设备发送第五请求消息，该第五请求消息用于请求该无线接入网设备确定中继节点，具体地，该第五请求携带该多个待测量的终端设备的标识(identity，ID)，该多个待测量的终端设备为具有支持sidelink能力的终端设备，该无线接入网设备根据该多个待测量的终端设备的ID列表选择其中的一个终端设备作为中继节点。例如，该无线接入网设备根据ID列表中终端设备所在小区的位置选择中继节点。
在另一种可能的实现方式中，LMF确定该多个待测量的终端设备共同的一个无线接入网设备为该中继节点。
在LMF选择了中继节点之后，LMF与该中继节点和/或无线接入网设备进行信令交互，以确定中继节点的位置信息。LMF确定中继节点的位置信息可通过任意定位方法，例如，LMF向该中继节点发送请求消息，该请求消息用于请求该中继节点的测量数据，LMF接收中继节点发送的响应消息，该响应消息包括中继节点的测量数据或者位置估计信息。例如，LMF接收中继节点的测量数据可以包括到达时间差(time difference of arrival，TDOA)、参考信号接收功率(reference signal receiving power，RSRP)和到达角度(angle of arrival,AoA)等，LMF根据测量数据确定中继节点的位置信息；或者，LMF接收中继节点发送的由全球导航卫星系统(Global Navigation Satellite,GNSS)提供的测量值，该测量值作为中继节点的位置估计信息。或者，当该中继节点为无线接入网设备时，LMF向该无线接入网设备发送位置请求消息，该位置请求消息用于请求该无线接入网设备的位置信息。
在S420中，LMF获取多个待测量的终端设备的测量信息。
其中，终端设备的测量信息可以是以下信息中的至少一项：终端设备的标识、终端设备的测量数据、终端设备相对于中继节点的相对位置信息。
具体地，在一种可能的实现方式中，该多个待测量的终端设备可以为LMF已知的多个待测量的终端设备。
LMF通过该中继节点获取该多个待测量的终端设备的测量数据，或者，LMF通过该中继节点获取由该中继节点确定的该多个待测量的终端设备相对于该中继节点的相对位置信息，其中，该相对位置信息由该中继节点根据该多个终端设备的测量数据确定。
在另一种可能的实现方式中，该多个待测量的终端设备为LMF未知的多个终端设备，LMF通过该中继节点获取由该中继节点确定的多个待测量的终端设备的标识，或者，LMF通过该中继节点获取由该中继节点确定的多个待测量的终端设备的标识以及该多个待测量的终端设备的测量数据，或者，LMF通过该中继节点获取由该中继节点确定的多个终端设备的标识以及该多个终端设备相对于该中继节点的相对位置信息。
应理解，上述两个过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定，例如S410可以在S420执行的任意时刻执行。
在S430中，LMF根据该中继节点的位置信息以及该多个待测量的终端设备的测量信息确定该多个待测量的终端设备的位置信息。
