Description

一种定位方法、装置和系统 技术领域
本申请涉及通信领域，尤其涉及一种定位方法、装置和系统。
背景技术
定位服务是一种运营商为用户提供的与位置相关的服务，定位服务可以被应用到各种不同的领域，比如交通领域或者社交领域。定位服务一般由定位服务客户端发起。以第五代移动通信系统提供定位服务为例，定位服务的实现流程中包括以下的步骤：
定位服务客户端向移动位置网关发送终端的定位请求消息，请求获取该终端的定位信息；移动位置网关从统一数据管理网元接收接入与移动性管理功能网元的信息，该接入与移动性管理功能网元为当前为终端服务的接入与移动性管理功能网元；移动位置网关向该接入与移动性管理功能网元发送定位请求消息；接入与移动性管理功能网元选择位置管理功能网元，并向位置管理功能网元发送定位请求消息；位置管理功能网元从终端和/或无线接入网获取测量信息，并根据该测量信息计算终端的位置信息；位置管理功能网元向接入与移动性管理功能网元发送终端的位置信息；接入与移动性管理功能网元向移动位置网关发送终端的位置信息；最终，移动位置网关向定位服务客户端发送终端设备的位置信息。
然而，上述定位服务的实现流程中涉及到的接入与移动性管理功能网元部署于运营商网络中，例如运营商集中部署的核心网，在一些应用场景中，由于数据安全的要求，终端设备的位置信息不能被运营商网络所获取，因此现有的定位服务不能满足用户的需要。
发明内容
本申请实施例提供一种定位方法、装置和系统，用于实现对终端的定位，并能够提高用户数据的安全性。
第一方面，本申请实施例提供一种定位方法，该方法包括：
接入与移动性管理功能网元接收用于对终端定位的第一请求；接入与移动性管理功能网元根据第一请求指示接入网设备建立与位置管理功能网元之间的连接，或者建立与位置管理功能网元对应的网关的连接；接入网设备将终端的测量信息通过连接发送给位置管理功能网元，或者通过连接发送给网关，网关将终端的测量信息发送给位置管理功能网元；位置管理功能网元根据测量信息获取终端的定位结果；位置管理功能网元发送定位结果。在上述方法中，接入与移动性管理功能网元在接收到对终端的定位请求后，指示接入网设备与位置管理功能网元建立连接，或者与该位置管理功能网元对应的网关的连接，从而使得接入网设备能够将终端的测量信息，直接发送给位置管理功能网元，或通过位置管理功能网元对应的网关发送给位置管理功能网元。由于上述定位过程中，终端的测量信息没有被发送至接入与移动性管理功能网元，对于接入企业网络的终端，上述发送过程避免了将用户数据发送至企业网络之外，有助于满足用户对数据安全的需要。
此外，在一种可能的网络架构中，位置管理功能网元设置在移动边缘网络中，接入与移动性管理功能网元仍集中部署在运营商的核心网中，那么对于接入移动边缘网络的终端来说，由于移动边缘网络中的位置管理功能网元与终端的距离，比接入与移动性管理功能 网元与终端的距离更近，接入网设备直接(或通过网关)将测量信息发送给位置管理功能网元的方式，与通过接入与移动性管理功能网元转发给位置管理功能网元的方式相比，传输时延更低，有助于降低终端定位的时延，提高用户体验。

本申请以5G网络为例，图1A所示为本申请适用的一种5G网络的网络架构。上述网络架构中均可包括以下几个部分，分别是终端、无线接入网(radio access network，RAN)、核心网。
下面对该网络架构中涉及的部分进行具体说明：
终端设备，是一种具有无线收发功能的设备。终端设备通过无线方式与无线接入网相连，从而接入到通信系统中。终端设备也可以称为终端、用户设备、移动台、移动终端等。终端设备可以是手机、平板电脑、带无线收发功能的电脑、虚拟现实终端设备、增强现实终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程手术中的无线终端、智能电网中的无线终端、运输安全中的无线终端、智慧城市中的无线终端、或智慧家庭中的无线终端等等。本申请实施例对终端设备所采用的具体技术和具体设备形态不作限定。作为示例而非限定，终端设备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。终端设备还可以是作为一个或多个部件或者单元而内置于车辆的车载模块、车载部件、车载芯片或者车载单元，车辆通过内置的所述车载模块、车载模组、车载部件、车载芯片或者车载单元可以实施本申请的方法。
无线接入网用于实现无线有关的功能。无线接入网又可称为接入网设备或基站，用于将终端设备接入到无线网络。所述无线接入网可以是基站(base station)、LTE系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(evolved NodeB，eNodeB)、5G通信系统中的下一代基站(next generation NodeB，gNB)、发送接收点(transmission reception point，TRP)、基带单元(base band unit，BBU)、WiFi接入点(access point，AP)、未来移动通信系统中的基站或WiFi系统中的接入节点等。无线接入网也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，或者分布式单元(distributed unit，DU)。本申请实施例对无线接入网所采用的具体技术和具体设备形态不作限定。例如，在一种网络结构中，无线接入网可以为CU节点、或DU节点、或为包括CU节点和DU节点的无线接入网。具体的，CU节点用于支持无线资源控制(radio resource control，RRC)、分组数据汇聚协议(packet data convergence protocol，PDCP)、业务数据适配协议(service data adaptation protocol，SDAP)等协议；DU节点用于支持无线链路控制(radio link control，RLC)层协议、媒体接入控制(medium access control，MAC)层协议和物理层协议。
核心网可包括以下网元中的一个或多个：接入与移动性管理功能(access and mobility management function，AMF)网元、会话管理功能网元(session management function，SMF) 网元、用户面功能(user plane function，UPF)网元、应用功能(application function，AF)网元、策略控制功能(policy control function，PCF)网元、统一数据管理(unified data management，UDM)网元。需要说明的是，5G网络中包括并不限于以上提到的一个或多个网元。
AMF：主要用于移动网络中的终端的附着和移动性管理。
SMF：主要用于移动网络中的会话管理，如会话建立、修改、释放。具体功能如为终端分配互联网协议(internet protocol，IP)地址、选择提供报文转发功能的用户面网元等。
UPF：主要负责对用户报文进行处理，如转发、计费、合法监听等。用户面网元也可以称为协议数据单元(protocol data unit，PDU)会话锚点(PDU session anchor，PSA)。
AF：主要用于向终端设备提供应用层服务。应用功能网元代表应用与其他控制网元进行交互，包括提供服务质量(quality of service，QoS)需求、计费(charging)策略(policy)需求和路由策略需求等。
PCF：包含用户签约数据管理功能、策略控制功能、计费策略控制功能、服务质量(quality of service，QoS)控制等。
UDM：负责管理终端的签约信息。
以上“网元”也可以称为“实体”或“装置”，本申请并不做限制。在实际部署中，网元可以合设，当两个网元合设的时候，本申请实施例提供的这两个网元之间的交互就成为该合设网元的内部操作或者可以省略。
数据网络：为终端提供数据传输服务，可以是公用数据网(public data network，PDN)网络，如因特网(internet)等，也可以是本地接入数据网络(local access data network，LADN)，如移动边缘计算(mobile edge computing，MEC)节点的网络等。
图1B为本申请实施例适用的一种定位架构的示意图。该定位架构是一种基于图1A所示的5G网络的定位架构，在定位架构中，除了终端设备以及无线接入网以外，主要涉及到核心网中以下几种网元或者装置：接入与移动性管理功能网元、位置管理功能(location management function，LMF)网元、网络开放功能(network exposure function，NEF)网元、统一数据管理网元、应用功能网元以及移动位置网关(gateway mobile location centre，GMLC)。其中，LMF主要负责终端设备的位置信息的计算与管理；NEF主要用于对外提供5G网络能力和事件的开放，以及接收相关的外部信息等；GMLC主要与终端设备的定位服务有关，GMLC与定位服务(location services，LCS)客户端相连，获取该定位服务客户端指定的终端设备的定位需求，并向核心网中的AMF发送该定位需求，请求核心网反馈终端设备的位置信息。该GMLC与UDM、NEF以及AMF均有接口。特别指出的是，LCS客户端属于外部的应用程序，例如地图类应用程序。
在图1B所示的该定位架构中，以第五代移动通信系统提供定位服务为例，定位服务的实现流程中包括以下的步骤：
LCS客户端向GMLC发送终端设备的定位请求消息，请求获取该终端设备的定位信息；GMLC从UDM接收AMF的信息，该AMF为当前为终端设备服务的AMF；GMLC向该AMF发送定位请求消息；AMF选择LMF，并向LMF发送定位请求消息；LMF从终端设备和/或RAN获取测量信息，并根据该测量信息计算终端设备的位置信息；LMF向AMF发送终端设备的位置信息；AMF向GMLC发送终端设备的位置信息；最终GMLC向LCS客户端发送终端设备的位置信息。
随着通信系统的不断演进，移动边缘计算技术应运而生。移动边缘计算技术是第五代移动通信中的一项重要的技术，该技术可以满足行业数字化在敏捷连接、实时业务、数据优化、应用智能、安全与隐私保护等方面的关键需求。为了实现该技术，核心网中部分功能网元可以部署于移动边缘网络中，而移动边缘网络部署的位置与核心网部署的位置相比，距离终端设备更加近。原本位于云数据中心的部分服务和功能可以由移动边缘网络实现，移动边缘网络为用户提供计算、存储等通信服务。若用户所需的服务可以由移动边缘网络实现，则通信的时延可以得到降低，用户服务体验也能够得到提升。
终端设备可以位于运营商提供的移动边缘网络中，也可以位于其他数据网络中，如企业网络等。以企业网络为例，企业网络中也可以包括企业LMF及GMLC等。出于对用户数据的安全考虑，用户希望终端设备的用户数据仅在企业网络中传输，而不希望用户数据被发送至运营商的网络中。而上述的定位服务流程中终端设备的用户数据(如测量信息、定位结果等)被发送至运营商提供的AMF中，无法满足用户对数据安全的需求。
因此，本申请提供一种定位方法，用于实现对终端的定位，并提升了终端的定位信息的安全性。
图2A和图2B以5G移动通信系统为例，示例性的提供了本申请实施例所能够适用的网络架构。图2A和图2B所示的网络架构可以包括终端设备、RAN、AMF、LMF、GMLC，进一步的还可以包括UDM、LCS客户端等。图2B所示网络架构与图2A所示网络架构的区别在于，图2B所示网络架构中的LMF所在的数据网络还包括信令网关，即，来自RAN的消息需要通过信令网关转发给LMF。不论是图2A还是图2B所示网络架构，其中的LMF和GMLC可以合并部署，即部署在同一物理设备上，也可以单独部署；在图2B所示网络架构中，信令网关还可以与LMF合并部署，或者，还可以将信令网关、LMF和GMLC进行合并部署。此外，定位服务客户端也可以为其他形式的边缘应用服务器(edge application server，EAS)，且一个数据网络中可以部署一个或多个定位服务客户端，本申请并不限制。
本申请实施例所涉及的接入网设备，可以是现有4G、5G移动通信系统中的无线接入网设备，也可以是未来移动通信系统中具有无线接入功能的设备；接入与移动性管理功能网元，为具有接入与移动性管理功能的网元，可以是5G移动通信系统中的AMF，也可以是4G或未来通信系统中具有接入与移动性管理功能的网元；位置管理功能网元，为具有位置管理功能的网元，可以是5G移动通信系统中的LMF，也可以是4G或未来通信系统中具有位置管理功能的网元；信令网关为终端所接入网络中在接入网设备和位置管理功能网元之间的具有网关作用的网元；移动位置网关，可以是5G移动通信系统中的GMLC，也可以是4G或未来通信系统中具有移动位置网关功能的网元；统一数据管理网元，为具有数据管理功能的网元，可以是5G移动通信系统中的UDM，也可以是4G或未来通信系统中具有数据管理功能的网元。
为了方便描述，下文中将终端设备简称为UE，接入网设备简称为RAN，接入与移动性管理功能的网元简称为AMF，位置管理功能网元简称为LMF，信令网关简称网关，移动位置网关简称为GMLC，定位服务客户端简称为LCS客户端，统一数据管理网元简称为UDM。
图3为本申请实施例提供的定位方法实施例的流程示意图，该方法中，网络架构中不包括网关，或者将LMF与网关合并设置。该方法可以包括以下步骤：
步骤301，AMF接收用于对UE定位的第一请求。
该第一请求中可以携带指示信息，以指示该UE的定位流程与传统定位流程不同，例如，后续步骤中RAN将UE的测量信息直接发送给LMF，并且，LMF在得到UE的定位结果后，直接将该UE的定位结果发送给GMLC或客户端。该指示信息可以是显式的，也可以是隐式的，隐式的指示信息可以为字段信息，例如，该字段信息可以用于指示对该UE进行定位的LMF的信息，如LMF的地址或者LMF的标识；该字段信息也可以指示该UE所接入的网络的标识(如移动边缘网络或企业网络的标识)；或者，该字段信息还可以用于指示在该UE的位置信息(如UE所处蜂窝小区(cell)的信息、UE所接入的RAN的标识信息等)。
可选的，该第一请求中还可以包括UE的定位要求信息，例如定位的QoS需求信息、UE是否支持LTE定位协议(LTE positioning protocol，LPP)等。
步骤302，AMF根据第一请求指示RAN建立与LMF之间的连接。
在一种可能的实现方式中，AMF在接收到第一请求后，可以根据第一请求，确定出用于对UE进行定位的LMF，进而指示RAN与确定出的LMF建立连接。
例如，若第一请求中包括LMF的信息(如LMF的标识或地址)，AMF可以将LMF的信息发送给RAN，或者AMF根据LMF的标识确定出LMF的地址并发送给RAN，以使RAN与LMF建立连接。其中，LMF的地址可以为全域名(full qualified domain name，FQDN)，也可以是LMF与RAN的接口地址，如LMF的N2地址信息。
又例如，若第一请求中包括UE所接入的网络的标识，例如，数据网络接入标识(data network access identifier，DNAI)，AMF可以根据自身预先配置的信息获取该标识所对应的网络中的LMF的信息，例如AMF预先配置了DNAI所对应的LMF的信息，并将该LMF的信息发送给RAN；或者，AMF也可以从其他网元(如网络存储功能网元、网络注册功能网元、边缘网络平台、用户数据存储功能网元等)获取UE接入的网络的标识所对应的LMF，然后将LMF的信息发送给RAN。在一种可能的实现方式中，DNAI所对应的LMF的信息可以由企业网络或移动边缘网络通过NEF存储到统一数据存储(unified data repository，UDR)中，例如，移动边缘网络通过应用影响流程(AF influence procedure)将LMF的信息存储到UDR中，后续PCF从UDR中获取LMF的信息并将该LMF的信息发送给AMF。
再例如AMF可以根据UE的位置信息，确定UE所接入的网络，进而确定UE接入的网络中的LMF，同样的，AMF可以根据自身预先配置的信息确定LMF的信息，也可以从其他网元获取LMF的信息，然后将LMF的信息发送给RAN。
若第一请求中未包含LMF的信息，且UE所接入网络中包括多个LMF，AMF还可以根据预先配置的策略，例如负载均衡策略，从多个LMF中选择用于对UE定位的LMF，再将选择的LMF的信息发送给RAN。
在另一种可能的实现方式中，若第一请求中没有包含LMF的标识和地址，AMF也可以不确定LMF的标识或地址，而是将其他可以用于确定LMF的信息发送给RAN，由RAN确定相应的LMF。RAN根据UE接入网络的标识或UE的位置信息确定LMF的过程与AMF确定的过程类似，此处不再赘述。
步骤303，RAN将UE的测量信息通过与LMF的连接发送给LMF。
在RAN与LMF建立连接后，RAN将UE用于定位的测量信息通过与LMF的连接发送给LMF，从而避免了将UE的测量信息发送给AMF，再由AMF转发给LMF的过程。
步骤304，LMF根据UE的测量信息获取UE的定位结果，并发送该定位结果。
在一种可能的实现方式中，上述步骤301中AMF所接收到的第一请求可以是GMLC发送的，则AMF可以将GMLC的信息发送给LMF，其中，GMLC的信息可以包括GMLC的标识或地址，例如，GMLC的通知地址信息，该通知地址信息可以为统一资源标识符(notification Uniform Resource Identifier，notification URI)。则LMF在得到UE的定位结果后，根据该GMLC的信息将定位结果发送给GMLC。在一个具体场景中，LCS客户端可以向GMLC发送定位请求，以请求为UE进行定位，该定位请求信息中包括被定位的UE的信息，例如，UE的标识。GMLC向UDM发送该UE的信息，并从UDM获取为该UE服务的AMF的信息。然后，GMLC向AMF发送用于对UE定位的第一请求，第一请求中包括GMLC的信息，AMF将GMLC的信息发送给LMF，则LMF可以根据该GMLC的信息向GMLC发送定位结果，GMLC在将定位结果发送给LCS客户端。
在另一种可能的实现方式中，LMF与GMLC可以合并设置，LCS客户端可以向LMF发送定位请求，即，LMF向AMF发送步骤301中的第一请求；在LMF得到UE的定位结果后，将定位结果发送给LCS客户端。
在上述方法中，AMF在接收到对UE的定位请求后，指示RAN与LMF建立连接，或者与该LMF对应的网关建立连接，从而使得RAN能够将UE的测量信息，直接发送给LMF，或通过LMF对应的网关发送给LMF。由于上述定位过程中，UE的测量信息没有被发送至接入与移动性管理功能网元，对于接入企业网络的UE，上述发送过程避免了将用户数据发送至企业网络之外，有助于满足用户对数据安全的需要。对于接入移动边缘网络的UE，由于移动边缘网络中的LMF与UE距离更近，RAN直接(或通过网关)将测量信息发送给LMF的方式，与RAN将测量信息通过AMF转发给LMF的方式相比，传输时延更低，有助于降低UE定位的时延，提高用户体验。
在上述步骤302中，AMF指示RAN与LMF之间建立连接，该连接为UE级别的连接，即，该连接用于传输该UE的相关信息。
在一种可能的实现方式中，RAN与LMF建立连接时，LMF可以接收来自RAN的第一标识，该第一标识为RAN为UE分配的标识，例如，该第一标识可以是“RAN NGAP UE ID for LCS”。该第一标识是用于RAN识别该UE或者用于RAN识别该连接。该第一标识可以用于，当LMF向RAN发送关于该UE的消息时，如LMF向RAN发送下行定位消息，该下行定位消息包括该第一标识，RAN可以根据该第一标识确定被定位的UE，从而向LMF发送该UE测量信息，例如RAN向LMF发送包含有UE测量信息的上行定位消息。或者，LMF也可以通过其他消息向RAN发送该第一标识。
其中，LMF接收的来自RAN的第一标识，可以是RAN直接向LMF发送第一标识，也可以是RAN将第一标识发送给AMF，然后AMF将第一标识发送给LMF。
此外，LMF可以向RAN发送第二标识，该第二标识为LMF为UE分配的标识，例如，该第二标识可以是“LMF NGAP UE ID”。该第二标识用于LMF识别该UE或者用于LMF识别该连接。该第二标识可以用于，当RAN向LMF发送上行定位消息时，该上行定位消息包括该第二标识，LMF可以根据该第二标识确定被定位的UE，并根据该上行定位消息中的测量信息对该UE进行定位。
可选的，LMF向RAN发送第二标识时，LMF发送的消息可以为新空口定位协议a(New Radio Positioning Protocol a，NRPPa)消息，该NRPPa消息中包括第一标识和第二标识， 以实现通知RAN：LMF为第一标识对应的UE分配了第二标识。
LMF也可以不为UE分配第二标识，也采用第一标识对被定位的UE进行识别。
RAN和LMF交互了各自对UE分配的标识后，即实现了RAN与LMF建立UE级别的连接。
在另一种可能的实现方式中，LMF也可以不分配第二标识，若LMF与GMLC合并设置，此时，GMLC可以向AMF发送关于UE的上下文标识信息，例如，该上下文标识信息可以为路由标识(routing ID)，AMF将该上下文标识信息发送给RAN，以使RAN向LMF发送信息时携带该上下文标识，LMF则能够根据该上下文标识确定相应的UE。
在RAN与LMF建立UE级别的连接之前，RAN与LMF先建立链路，该链路为网元级别的链路，即，该链路用于实现RAN与LMF之间的通信，该链路可以为多个不同的UE使用。例如，RAN与LMF可以建立流控制传输协议(Stream Control Transmission Protocol，SCTP)链路，该连接方式可以称为流控制传输协议耦连。
而RAN与LMF建立网元级别链路的过程，可以是由定位服务触发的，即，在AMF指示RAN与LMF建立连接时，先建立网元之间的链路，然后再根据上述实施例建立UE级别的连接。例如，AMF在接收到第一请求后，可以通过RAN向UE发送寻呼消息，以使空闲态的UE成为连接态，AMF可以在寻呼过程中向RAN发送LMF的接口地址，以使RAN与LMF建立SCTP链路。
或者，RAN与LMF之间的网元级别的链路，也可以是预先建立的。例如，RAN可以预先配置有移动边缘网络的LMF的信息，并与其建立网元级别的链路，以方便后续RAN和LMF之间的通信。
RAN可以根据LMF的接口地址与LMF建立网元级别的链路，若RAN接收到的不是LMF的接口地址，RAN可以查询本地预配置信息或者查询域名服务器(domain name server，DNS)以获取LMF的接口地址。
进一步的，LMF对UE进行定位时，还获取UE的定位要求信息。此时，LMF可以从AMF处获取定位要求信息，或者从GMLC获取定位要求信息，在LMF向RAN发送下行定位消息以获取UE测量信息时，LMF根据获取到的定位要求信息确定发送给RAN的下行定位消息，其中，该下行定位消息也可以有其他的名称，本申请的实施例中不做限制。具体的，LMF可以通过以下方式从AMF处获取UE的定位要求信息：
方式一，LMF根据第一标识从AMF获取UE的定位要求信息。
如前所述，RAN为UE分配第一标识，并将第一标识发送给LMF，或者将第一标识发送给AMF，由AMF发送给LMF。
若RAN直接将第一标识发送给LMF，RAN还可以将第一标识发送给AMF，以使AMF将第一标识和该UE关联；然后LMF向AMF发送第二请求，该第二请求中包括第一标识，AMF根据第二请求中的第一标识确定被定位的UE，并将该UE的定位要求信息发送给LMF。
若RAN没有将第一标识给送给LMF，而是通过AMF转发，则AMF在将第一标识发送给LMF时，可以将该UE的定位要求信息和第一标识发送给LMF。
方式二，LMF根据AMF为UE分配的第三标识从AMF获取UE的定位要求信息。
AMF也可以为UE分配第三标识，例如，该第三标识可以是“AMF NGAP UE ID”。AMF将第三标识发送给RAN；RAN将第三标识发送给LMF(第三标识可以与第一标识一 同由RAN向LMF发送)；LMF向AMF发送第二请求，该第二请求中包括第三标识；AMF根据第二请求中的第三标识确定被定位的UE，并将该UE的定位要求信息发送给LMF。
由于方式二中AMF没有执行第一标识的转发，因此，进一步降低了AMF获取UE的测量信息等用户数据的可能，该方式进一步提高了用户的安全性。
方式三，LMF根据RAN为UE分配的第四标识从AMF获取UE的定位要求信息。
RAN除了为UE分配第一标识，还可以为UE分配一个临时标识，例如令牌(token)，称为第四标识。RAN将第四标识发送给LMF(第四标识可以与第一标识一同发送给LMF)，RAN还将第四标识发送给AMF，以使AMF将第四标识与该UE关联；LMF向AMF发送第二请求，该第二请求中包括第四标识；AMF根据第二请求中的第四标识确定被定位的UE，并将该UE的定位要求信息发送给LMF。
由于第一标识为用于获取UE定位信息的标识，而方式三中没有将第一标识发送给AMF，而是采用临时标识替代，因此，进一步降低了AMF获取UE的测量信息等用户数据的可能，有助于进一步提高用户的安全性。
方式四，LMF可以从GMLC获取UE的定位要求信息。
LMF还可以通过GMLC与LMF之间的接口，从GMLC获取UE的定位要求信息。
在上述方式一和方式三中，LMF主动向AMF发送第二请求，以获取UE的定位要求信息。可选的，RAN还可以将AMF的标识或地址发送给LMF，方便LMF确定为UE服务的AMF，进而从该AMF处获取UE的定位要求信息。
此外，步骤301中AMF所接收到的第一请求中，还可以包括用于指示周期性获取UE定位信息的指示信息，则AMF可以在向LMF发送UE的定位要求信息的同时，指示LMF周期性发送UE的定位结果；当然，AMF也可以将UE的定位要求信息和上述指示信息通过不同的消息发送给LMF。相应的，LMF向RAN发送的下行定位消息中，也包含有用于指示周期性上报UE的测量信息的指示信息。
为了更加清楚理解本申请上述实施例，下面结合图4和图5进行举例说明。
图4示例性的提供了另一种定位方法流程，如图所示，该方法可以包括以下步骤：
步骤401，LCS客户端向GMLC发送定位请求。
该请求中包括UE的信息。
其中，UE的信息可以是UE的标识。可选的，该定位请求信息中还可以包括周期性上报UE的位置信息的指示信息。
步骤402，GMLC获取AMF的信息。
GMLC可以向UDM发送该UE的信息，并从UDM获取为该UE服务的AMF的信息。
步骤403，GMLC向AMF发送定位请求消息。
定位请求消息即图3所示实施例中的第一请求，该定位请求消息中包括至少一种用于选择LMF的信息，例如，LMF的信息、UE所接入的网络的标识和UE的位置信息。用于选择LMF的信息包括但不限于上述示例。当LMF与GMLC没有合并设置时，该定位请求消息中还可以包括GMLC的接口地址，该GMLC的接口地址用于后续LMF向GMLC发送该UE的定位结果。
步骤404，AMF确定LMF。
AMF可以按照图3所示实施例步骤302中AMF确定LMF的方式进行确定，例如，AMF可以根据LMF的信息、UE所接入网络的标识或UE的位置信息确定用于对UE定位 的LMF。
步骤405，AMF向UE发送寻呼消息。当UE为空闲态时，AMF向UE发送寻呼消息。
步骤406，UE发送业务请求消息。当UE接收到寻呼消息后，UE向AMF发送业务请求消息。
步骤407，AMF向RAN发送LMF的N2地址信息。
如图2A或图2B所示，RAN与LMF之间的接口为N2接口，LMF的N2地址信息，即为LMF与RAN在N2接口的地址信息，是LMF与RAN通信时所用的接口地址。若步骤404没有被执行，那么在该步骤407中，AMF向RAN发送该用于选择LMF的信息。也就是说，选择LMF的动作可以由AMF来执行，也可以由RAN来执行，具体可参见图3所示实施例步骤302中RAN确定LMF的实现方式，该实施例中不再赘述。
步骤408，AMF向UE发送业务接收消息。
该业务接收消息为步骤406中的业务请求消息的响应消息。AMF可以通过RAN向UE发送业务接收消息，即AMF向RAN发送该业务接收消息，然后RAN向UE发送该业务接收消息。
可选的，步骤407还可以通过步骤408中AMF向RAN发送业务接收消息的步骤来实现，也就是说，步骤407中，AMF向RAN同时发送LMF的N2地址信息和业务接收消息。
此外，步骤405、步骤406和步骤408的目的是为了使得UE处于连接态，当UE处于连接态时，UE的定位才可以被实现。若UE为连接态，则步骤405和步骤406以及步骤408可省略。
步骤409，RAN与LMF建立链路。
若在此之前，RAN与LMF还没有建立网元级别的链路，则可以通过步骤409建立网元级别的链路，例如SCTP链路。
步骤410，RAN向AMF发送第一标识。
例如，RAN向AMF发送步骤407的响应消息，该响应消息中包括第一标识。
步骤411，AMF向LMF发送第一标识。
例如，AMF向LMF发送该UE的定位请求信息，该信息中包括第一标识。该定位请求信息中还可以包括UE的定位要求信息。
若在步骤403中AMF从GMLC接收了GMLC的通知地址信息，那么AMF在该步骤中还向LMF发送该GMLC的通知地址信息，以便后续步骤中，LMF获取UE的定位结果后向GMLC发送该结果。
LMF在收到定位请求信息后可以向AMF发送定位响应信息，图中不再示出。
步骤412，AMF向GMLC发送定位响应消息。该步骤中的定位响应消息为步骤403中的定位请求消息的响应消息，本申请对该步骤的执行顺序不做限定，也可以在步骤403后即执行。
步骤413，LMF向RAN发送第一标识、第二标识。
例如，LMF向RAN发送N2消息，该N2消息中包括第一标识和第二标识。RAN根据第一标识确定该N2消息所对应的UE，后续步骤中根据第二标识向LMF发送该UE的测量信息。
步骤414，RAN获取UE的测量信息。
步骤415，RAN向LMF发送第二标识和测量信息。
例如，RAN向LMF发送步骤413中的N2消息的响应消息，该响应消息中包括第二标识和测量信息。
若后续RAN主动向LMF上报测量信息时，RAN同样向LMF发送第二标识和测量信息。比如，RAN收到周期性上报UE的位置信息的指示信息，RAN主动向LMF上报测量信息。
可选的，RAN在发送测量信息时还可以发送第一标识。
步骤416，LMF向GMLC发送UE的定位结果。
LMF根据测量信息，计算出UE的定位结果，并向GMLC发送该UE的定位结果。
若LMF与GMLC合设，GMLC可以通过步骤415直接获取到该位置信息，此时步骤416可省略。若LMF与GMLC没有合设，那么LMF根据GMLC的通知地址，向GMLC发送该UE的位置信息。
步骤417，GMLC向LCS客户端发送UE的定位结果。
图5示例性的提供了又一种定位方法流程，如图所示，该方法可以包括以下步骤：
步骤501，LCS客户端向GMLC发送定位请求。该请求中包括UE的信息。
步骤502，GMLC获取AMF的信息。
步骤503，GMLC向AMF发送定位请求消息。

步骤507，AMF向RAN发送LMF的N2地址信息。
步骤508，AMF向UE发送业务接收消息。
步骤509，RAN与LMF建立链路。
步骤501至步骤509可参考图4所示实施例中步骤401至步骤409的描述。
其中，在步骤507中，若GMLC与LMF没有合设，那么AMF可以还向RAN发送AMF的标识，该AMF的标识用于后续LMF向该AMF请求获取UE的定位要求信息，如定位服务质量要求。可选的，步骤507中AMF还可以向RAN发送第三标识，即图3所示实施例中AMF为UE分配的标识，其作用如图3所示实施例中的方式二所述，用于实现LMF根据第三标识从AMF获取UE的定位要求信息。
步骤510，RAN向AMF发送响应消息。
该响应消息可以为步骤507的响应消息。
可选的，该响应消息中可以包括第一标识，如图3所示实施例中的方式一所述，以使LMF能够根据第一标识从AMF获取UE的定位要求信息。
可选的，该响应消息中还可以包括第四标识，即图3所示实施例中方式三所述的第四标识，用于实现LMF能够根据第四标识从AMF获取UE的定位要求信息。
步骤511a，RAN向LMF发送第一标识。
RAN可以向LMF发送N2消息，该N2消息中包括第一标识。
可选的，该N2消息中还可以包括AMF的标识，该AMF的标识用于后续LMF向该AMF请求获取关于UE的定位要求信息。
可选的，若步骤507中AMF向RAN发送了第三标识，该N2消息中还可以包括第三 标识，以使LMF能够根据第三标识从AMF获取UE的定位要求信息，且步骤510中RAN向AMF发送的响应消息中不包括第一标识。
可选的，该N2消息中还可以包括第四标识，以使LMF能够根据第四标识从AMF获取UE的定位要求信息，且步骤510中RAN向AMF发送的响应消息中不包括第一标识。
步骤511b，LMF向AMF发送定位要求请求消息。该定位要求请求消息即为图3所示实施例中的第二请求，以请求获取UE的定位要求信息。
第二请求可以包括第一标识、第三标识或第四标识。AMF根据第一标识、第三标识或第四标识确定UE的定位要求信息。
步骤511c，AMF向LMF发送定位要求响应消息，该响应消息包括UE的定位要求信息。
当GMLC与LMF合设的情况下，步骤511b和步骤511c可省略。
步骤511d，LMF向RAN发送第一标识和第二标识。
例如，LMF向RAN发送N2消息，该N2消息中包括第一标识和第二标识。该N2消息用于建立LMF与RAN间的连接，以便RAN通过该连接发送该UE的定位测量信息。
RAN根据第一标识确定该N2消息所对应的UE，后续步骤中根据第二标识向LMF发送该UE的消息。
步骤512，LMF向RAN发送第一标识。
LMF可以根据定位要求信息向RAN发送N2消息，该N2消息携带有第一标识，该N2消息用于请求RAN向LMF发送该UE的定位测量信息。具体的，LMF根据定位要求信息确定RAN需要上报的测量信息和/或如何上报测量信息，例如，RAN确定是否需要周期性发送定位测量信息，并在N2消息中指示RAN是否需要周期性发送定位测量信息。
步骤512可以与步骤511d合并执行，即，在建立连接的过程中指示RAN上报UE的定位测量信息。
步骤513，RAN获取UE的测量信息。
步骤514，RAN向LMF发送第二标识和测量信息。
步骤515，LMF向GMLC发送UE的定位结果。
步骤516，GMLC向LCS客户端发送UE的定位结果。
图6为本申请实施例提供的又一种定位方法实施例的流程示意图，该方法中，网络架构中包括网关，但网关仅对RAN和LMF之间的交互信令进行转发，而不识别UE的信息。具体的，该方法可以包括以下步骤：
步骤601，AMF接收用于对UE定位的第一请求。
此处的第一请求与步骤301中的第一请求类似，其区别在于，步骤301中的第一请求可以包括LMF的信息、UE所接入网络的标识和UE的位置信息中的至少一项，而步骤601中的第一请求可以包括LMF的信息、UE所接入的网络的标识、UE的位置信息和网关的信息中的至少一项。其中，网关的信息包括网关的标识或网关的地址。具体的，网关的地址可以是全域名，也可以是网关与RAN的接口地址。
步骤602，AMF根据第一请求指示RAN通过网关建立与LMF之间的连接。
在一种可能的实现方式中，AMF在接收到第一请求后，可以根据第一请求确定出用于对UE进行定位的LMF所对应的网关。如前所述，第一请求中可以包含网关的信息，则AMF直接确定出相应的网关。若第一请求中包含有LMF的信息，则AMF可以根据自身 预先配置的信息，确定与该LMF所对应的网关，或者，AMF也可以根据LMF的信息，从其他网元获取与该LMF所对应的网关的标识或地址(如网关的地址或标识保存在LMF的配置文件中，AMF从NRF获取LMF的配置文件从而获取该LMF对应的网关的地址或标识)。若第一请求中包含有UE所接入的网络的标识，AMF获取网关的标识或地址的方法可参见图3所示实施例中AMF根据UE所接入的网络的标识获取LMF的标识或地址的方法，将其中的LMF替换为网关即可。AMF可以根据UE的位置信息，确定UE所接入的网络，进而确定UE接入网络中的网关；AMF在确定了网关的地址或标识后，将网关的标识或地址发送给RAN。此外，AMF可以不感知网关与LMF是合设还是分设，AMF可将网关看作LMF的一个接口。
在另一种可能的实现方式中，若第一请求中没有包含网关的标识和地址，AMF也可以不确定网关的标识或地址，而是将LMF的信息、UE所接入网络的标识或UE的位置信息发送给RAN，由RAN确定相应的网关。RAN根据LMF的信息、UE接入网络的标识或UE的位置信息确定网关的过程与AMF确定的过程类似，此处不再赘述。
步骤603，RAN将UE的测量信息通过建立的连接发送给LMF。
在RAN通过网关与LMF建立连接后，RAN将UE用于定位的测量信息通过网关发送给LMF，从而避免了将UE的测量信息发送给AMF，再由AMF转发给LMF的过程。
步骤604，LMF根据测量信息获取UE的定位结果，并发送定位结果。
在一种可能的实现方式中，步骤601中AMF接收到的第一请求，可以是LMF在接收到LCS客户端发送的定位请求后向AMF发送的，那么在步骤304中，LMF在确定出定位结果后，可以将定位结果发送给LCS客户端。在另一种可能的实现方式中，AMF接收到的第一请求可以是GMLC发送的，那么AMF可以将GMLC的信息发送给LMF，则LMF在得到UE的定位结果后，向GMLC发送UE的定位结果。
与图3所示实施例类似，图6所示实施例的目的也是避免在定位服务流程中将测量信息发送给AMF，以UE接入企业网络的场景为例，该实施例所提供的方法避免了将用户数据发送至企业网络之外，有助于满足用户对数据安全的需要，此外，对于接入移动边缘网络的UE，有助于降低UE定位的时延，提高用户体验。
在上述步骤602中，AMF指示RAN通过网关与LMF之间建立连接，该连接为UE级别的连接，即，该连接用于传输该UE的相关信息。
在一种可能的实现方式中，RAN通过网关与LMF建立连接时，LMF可以接收来自RAN的第一标识，该第一标识为RAN为UE分配的标识。该第一标识用于RAN识别该UE或者用于RAN识别该连接。该第一标识可以用于，当LMF通过网关向RAN发送关于该UE的消息时，如LMF向RAN发送下行定位消息，该下行定位消息包括该第一标识，RAN可以根据该第一标识确定被定位的UE，从而向LMF发送该UE测量信息，例如RAN向LMF发送包含有UE测量信息的上行定位消息。
其中，LMF接收的来自RAN的第一标识，可以是RAN通过网关向LMF发送第一标识，也可以是RAN将第一标识发送给AMF，然后AMF将第一标识发送给LMF。
此外，LMF可以向RAN发送第二标识，该第二为LMF为UE分配的标识，该第二标识用于LMF识别该UE或者用于LMF识别该连接。该第二标识可以用于，当RAN向LMF发送上行定消息时，该上行定位消息包括该第二标识，LMF可以根据该第二标识确定被定位的UE，并根据该上行定位消息中的测量信息对该UE进行定位。当然，LMF也可以为 UE分配第二标识，也采用第一标识对被定位的UE进行识别。
进一步的，LMF还可以向网关发送订阅请求，以使网关在从RAN接收LMF所订阅的消息后，将该消息发送给LMF。例如，LMF可向网关订阅N2消息，以便网关从RAN收到N2消息时，将N2消息发送给LMF。该订阅请求中可以包括LMF的通知地址。可选的，该订阅请求还可以包括RAN的标识信息，例如，移动边缘网络与多个RAN相关联时，订阅请求中可以包括RAN的标识信息，即LMF请求订阅该标识信息所对应的RAN的消息。
RAN通过网关与LMF交互了各自对UE分配的标识后，即实现了RAN通过网关与LMF建立UE级别的连接。
在RAN通过网关与LMF建立UE级别的连接之前，RAN与网关先建立网元级别的链路，即，该链路用于实现RAN与LMF之间的通信，该链路可以为多个不同的UE使用。例如，RAN与LMF可以建立SCTP链路。而RAN与网关建立网元级别链路的过程，可以是由定位服务触发的，即，在AMF指示RAN通过网关与LMF建立连接时，先建立网元之间的链路，然后再根据上述实施例建立UE级别的连接。例如，AMF在接收到第一请求后，可以通过RAN向UE发送寻呼消息，以使空闲态的UE成为连接态，AMF可以在寻呼过程中，向RAN发送网关的接口地址。
或者，RAN也可以预先建立与网关之间的网元级别的链路。
在一种可能的实现方式中，LMF还可以从AMF获取UE的定位要求信息。例如，RAN不仅将第一标识通过网关发送给LMF，还将第一标识发送给AMF，则LMF可以根据第一标识从AMF获取UE的定位要求信息。又例如，RAN将第一标识发送给AMF，AMF则可以将第一标识和UE的定位要求信息发送给LMF。再例如，RAN接收AMF发送的第三标识，即AMF为UE分配的标识，然后将第三标识发送给LMF，则LMF可以根据第三标识从AMF获取UE的定位要求信息。又或者，RAN可以为UE分配第四标识，即临时标识，并将第四标识发送给AMF和LMF，则LMF可以根据第四标识从AMF获取UE的定位要求信息。
可选的，RAN还可以将AMF的标识或地址通过网关发送给LMF，方便LMF确定为UE服务的AMF，进而从该AMF处获取UE的定位要求信息。
为了更加清楚理解图6所示实施例，下面结合图7进行举例说明。

步骤711，AMF向LMF发送第一标识。
可选的，AMF还可以向LMF发送UE的定位要求信息和/或GMLC的通知地址信息。
可选的，AMF还可以向LMF发送网关的标识或地址，以及RAN的标识或地址。
步骤712，LMF向网关发送LMF的通知地址。
例如，LMF向网关发送订阅请求，订阅请求用于请求网关将RAN发送的UE的测量信息发送给LMF，该订阅请求可以包括LMF的通知地址，以便网关通过该通知地址信息向该LMF发送该UE相关的定位测量信息。
可选的，该LMF还可以向网关发送RAN的标识，若该移动边缘网络与多个RAN关联，该RAN的标识用于指示网关向LMF发送从该RAN接收到的测量信息。
在一种实现方案中(简称方案A)，该LMF还可以向网关发送第一标识和/或第二标识，以便网关将包括第一标识和/或第二标识所对应的UE的测量信息发送给该LMF。
在另外一种实现方案中(简称方案B)，网关为该连接分配路由标识和关联标识，其中，路由标识用于该网关在收到从LMF发送的N2消息后，在将该N2消息发送给RAN时携带，关联标识用于在响应消息中发送给LMF，以便LMF在发送N2消息时携带。
步骤713，LMF向网关发送第一标识和第二标识。
例如，LMF可以向网关发送N2消息，该N2消息中包括第一标识和第二标识。
可选的，步骤712中采用了方案B，LMF可以将关联标识和N2消息一起发送给网关。
可选的，LMF还将RAN的标识和N2消息一起发送给网关。
步骤714，网关向RAN发送第一标识和第二标识。
例如，网关向RAN发送N2消息，该N2消息中包括第一标识和第二标识。
在上述方案B中，网关可以将N2消息和路由标识一起发送给RAN。
RAN根据第一标识确定该消息所对应的UE，后续步骤中根据第二标识通过网关向LMF发送该UE的消息。
步骤715，RAN获取UE的测量信息。
步骤716，RAN向网关发送第二标识和测量信息。
在上述方案B中，RAN还可以将路由标识一起发送给网关。
例如，RAN向网关发送步骤714的响应消息，该响应消息中包括第二标识和测量信息。
若后续RAN主动通过网关向LMF上报测量信息时，RAN同样向网关发送第二标识和测量信息。
步骤717，网关向LMF发送第二标识和测量信息。
网关通过LMF的通知地址信息将第二标识和测量信息一起发送给LMF。
在上述方案A中，网关可以根据第一标识和/或第二标识确定LMF的通知地址信息。
在上述方案B中，网关可以根据RAN发送的路由标识确定LMF的通知地址信息。
步骤718，LMF向GMLC发送UE的定位结果。
LMF根据测量信息计算UE的定位结果，并将定位结果发送给GMLC。
步骤719，GMLC向LCS客户端发送UE的定位结果。
图8为本申请实施例提供的又一种定位方法实施例的流程示意图，该方法中，网络架构中包括网关，且网关对UE信息进行识别。具体的，该方法可以包括以下步骤：
步骤801，AMF接收用于对UE定位的第一请求。
此处的第一请求与步骤601中的第一请求类似，此处不再赘述。
步骤802，AMF根据第一请求指示RAN建立与LMF对应的网关的连接。
AMF可以在接收到第一请求后，根据第一请求确定出用于对UE进行定位的LMF所对应的网关，将网关的标识或地址发送给RAN，以使RAN与该网关建立连接。AMF确定用于对UE进行定位的LMF所对应的网关的方式，与前述实施例步骤602中的方式一致，此处不再赘述。
或者，AMF也可以不确定网关，而是将LMF的信息、UE所接入网络的标识或UE的位置信息发送给RAN，由RAN确定相应的网关。
步骤803，RAN将UE的测量信息通过建立的连接发送给网关。
在RAN与网关建立连接后，RAN将UE用于定位的测量信息通过该连接发送给网关，以使网关将UE的测量信息发送给LMF，从而避免了将UE的测量信息发送给AMF，再由AMF转发给LMF的过程。
步骤804，LMF根据测量信息获取UE的定位结果，并发送该定位结果。
如前述实施例所述，若第一请求为GMLC发送给AMF，AMF可以将GMLC的信息发送给LMF，则LMF在得到UE的定位结果后，向GMLC发送UE的定位结果。若LMF接收到LCS客户端发送的定位请求，然后LMF向AMF发送了第一请求，则LMF在确定出定位结果后，可以将定位结果发送给LCS客户端。
图8所示实施例的目的也是避免在定位服务流程中将测量信息发送给AMF，对于接入企业网络的UE，避免了将用户数据发送至企业网络之外，有助于满足用户对数据安全的需要；对于接入移动边缘网络的UE，有助于降低UE定位的时延，提高用户体验。
在上述步骤802中，AMF指示RAN与LMF对应的网关的连接，该连接为UE级别的连接，即，该连接用于传输该UE的相关信息。
在一种可能的实现方式中，RAN与网关建立连接时，RAN可以为UE分配第一标识，用于在RAN中对UE进行识别；网关也可以为UE分配第五标识，用于在网关中对UE进行识别。该第一标识用于RAN识别该UE或者用于RAN识别该连接，第五标识用于网关识别该UE或用于网关识别该连接。RAN向网关发送第一标识，网关可以将第一标识与该UE的第五标识关联；网关也可以向RAN发送第五标识，RAN也可以将第五标识与该UE的第一标识关联。
当网关接收到LMF发送的关于UE的第一下行定位消息后，根据UE所对应的第一标识，向RAN发送第二下行定位消息，该第二下行定位消息包括第一标识。RAN接收到第二下行定位消息后，获取第一标识对应UE的测量信息以及第一标识对应的第五标识，向网关发送上行定位消息，该上行定位消息包括UE的测量信息和第五标识。网关在接收到RAN发送的上行定位消息后，将UE的测量信息发送给LMF。
在另外一种可能的实现方式中，RAN与网关建立连接时，RAN可以将第一标识发送给AMF，AMF将第一标识发送给网关，以使网关将第一标识和该UE的第五标识关联。网关将第五标识发送给AMF，AMF向RAN发送第五标识，RAN也可以将第五标识与该UE的第一标识关联。
可选的，网关还可以将第五标识或第六标识发送给LMF，LMF在后续发送关于该终端的下行定位消息时，可以携带该第五标识或第六标识，以使网关根据第五标识或第六标识确定终端对应的第一标识。若网关向LMF发送第五标识，则网关在网关与LMF的接口上，也采用第五标识识别该UE，与网关在网关与RAN的接口上识别UE的标识一致。而第六标识也是网关为该终端分配的标识，与第五标识的区别在于，第六标识用于该网关在网关与LMF的接口上标识该UE，即，网关在网关与LMF的接口上识别UE的标识，与网关在网关与RAN的接口上识别UE的标识不同。进一步地，LMF还可以将其为终端分配的第七标识发送给网关，以使网关在接收到RAN发送的上行定位消息后，向LMF发送携带第七标识的上行定位消息，其中，第七标识是LMF为该终端分配的标识，用于LMF在该LMF与网关的接口上标识该终端。
此外，LMF还可以向网关发送请求，该请求中包括LMF的信息和第七标识，以实现向网关订阅UE的测量信息。网关在接收到UE的测量信息后，根据LMF的信息和第七标识将UE的测量信息发送给LMF。
在RAN与网关建立UE级别的连接之前，RAN与网关先建立网元级别的链路，例如可以建立SCTP链路。而RAN与网关建立网元级别链路的过程，可以是由定位服务触发的，即，在AMF指示RAN通过网关与LMF建立连接时，先建立网元之间的链路，然后再根据上述实施例建立UE级别的连接。或者，RAN也可以预先建立与网关之间的网元级别的链路。
如前述实施例所述，LMF还可以从AMF获取UE的定位要求信息。LMF可以通过以下方式从AMF获取UE的定位要求信息：
方式一，RAN将第一标识发送给网关后，网关将第一标识发送给LMF；RAN也向AMF发送第一标识，以使AMF将第一标识和该UE关联；然后LMF向AMF发送第二请求，该第二请求中包括第一标识，AMF根据第二请求中的第一标识确定被定位的UE，并将该UE的定位要求信息发送给LMF。
方式二，RAN接收AMF发送的第三标识，即AMF为UE分配的标识；RAN向网关发送该第三标识，网关将第三标识发送给LMF。LMF向AMF发送第二请求，该第二请求中包括第三标识，AMF根据第二请求中的第三标识确定被定位的UE，并将该UE的定位要求信息发送给LMF。
方式三，RAN为UE分配第四标识(临时标识)，将第四标识发送给网关，网关将第四标识发送给LMF；RAN还将第四标识发送给AMF，以使AMF将第四标识和该UE关联。LMF向AMF发送第二请求，该第二请求中包括第四标识；AMF根据第二请求中的第四标识确定被定位的UE，并将该UE的定位要求信息发送给LMF。
可选的，RAN还可以将AMF的标识或地址通过发送给网关，网关将其发送给LMF，方便LMF确定为UE服务的AMF，进而从该AMF处获取UE的定位要求信息。
为了更加清楚理解本申请上述实施例，下面结合图9进行举例说明。图9示例性的提供了又一种定位方法流程，如图所示，该方法可以包括以下步骤：

步骤908，AMF向UE发送业务接收消息。
步骤909，RAN与网关建立链路。
步骤908和步骤909可以参考前述实施例中步骤408和步骤409的描述，此处不再赘述。

可选的，响应消息中包括第四标识或第一标识，以使LMF可以根据第四标识或第一标识从AMF获取UE的定位要求信息。
步骤910b，RAN向网关发送第一标识。
