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是本申请提供的一种5G通信系统的架构示意图。如图1所示，该通信系统包括终端设备、下一代无线接入节点(next generation radio access node，NGRAN)、接入和移动性管理功能(access and mobility management function，AMF)网元、位置管理功能(location management function，LMF)网元、会话管理功能(session management function，SMF)网元、用户面功能(user plane function，UPF)网元。应理解，该系统还可能包括其他的网元但此处并未示出。下面对上面列举的各个网元进行介绍。
终端设备：可为用户设备(user equipment，UE)、手持终端、笔记本电脑、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication，MTC)终端或是其他可以接入网络的设备。
下一代无线接入节点(next generation radio access node，NGRAN)：属于接入网设备，主要负责空口侧的无线资源管理、服务质量(quality of service，QoS)管理、数据压缩和加密等功能。所述接入网设备可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在第五代(5th generation，5G)系统中，称为gNB；在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB)；在第三代(3rd generation，3G)系统中，称为节点B(Node B)等。
接入和移动性管理功能(access and mobility management function，AMF)网元：属于核心网网元，主要负责信令处理部分，例如：接入控制、移动性管理、附着与去附着以及网关选择等功能。AMF网元为终端设备中的会话提供服务的情况下，会为该会话提供控 制面的存储资源，以存储会话标识、与会话标识关联的SMF网元标识等。
位置管理功能(location management function，LMF)网元：该网元用于提供根据定位精度要求、时延要求等选择相应的定位方法、以及选择相应的通信协议来完成定位所需信息的交互。该LMF还用于为定位服务提供所需的其他信息，或者定位策略。
会话管理功能(session management function，SMF)网元：负责用户面网元选择，用户面网元重定向，因特网协议(internet protocol，IP)地址分配，承载的建立、修改和释放以及服务质量(quality of service，QoS)控制。
用户面功能(user plane function，UPF)网元：负责终端设备中用户数据的转发和接收。可以从数据网络接收用户数据，通过接入网设备传输给终端设备；UPF网元还可以通过接入网设备从终端设备接收用户数据，转发到数据网络。UPF网元中为终端设备提供服务的传输资源和调度功能由SMF网元管理控制的。
应理解，在图1所示的通信系统中，各网元的功能以及接口(例如：N1、N2、N3、N4、N6、N11)仅为示例性的，各个网元在应用于本申请的实施例中时，并非全部功能都是必需的。核心网的全部或者部分网元可以是物理上的实体网元，也可以是虚拟化的网元，在此不做限定。
图2是本申请提供的一种5G无线通信系统的架构示意图。在该通信系统中，终端设备通过3GPP接入技术和非3GPP接入技术接入核心网。如图2所示，该通信系统包括终端设备、NGRAN、非3GPP接入网设备、非3GPP互通功能(non-3gpp interworking function,N3IWF)网元、AMF、LMF、SMF、UPF，还可能包括其他的网元但此处并未示出；另外，N1、N2、N3、N4、N6、N11、Y1、Y2均用于表示不同的消息类型。与图1所示的3GPP无线通信系统的架构不同的是，增加了非3GPP接入网(non-3GPP access network)设备和非3GPP互通功能。下面将主要介绍这两个网元的功能，其他网元可以参考图1的描述。
非3GPP接入网(non-3GPP access network，N3GPP)设备：该网元允许终端设备和3GPP核心网之间采用非3GPP技术互连互通。其中，非3GPP技术例如：无线保(wirelessfidelity，Wi-Fi)、全球微波互联接入(worldwide interoperability for microwave access，WiMAX)网络等。图2中所示的本地公共陆地移动网络可以是终端设备的归属地公共陆地移动网络，即终端设备最先的注册的公共陆地移动网络。图2中所示的非3GPP接入网设备可以是不可信非3GPP接入网设备。相对于可信的非3GPP接入网设备可直接接入3GPP核心网，该不可信非3GPP接入网设备需要通过安全网关建立的安全隧道来与3GPP核心网互连互通。安全网关例如：演进型分组数据网关(evolved packet data gateway，ePDG)或非3GPP互通功能(non-3GPP interworking function,N3IWF)网元。
N3IWF网元：该网元为不可信的非3GPP接入网设备与3GPP核心网之间的安全网关。
应理解，在图2所示的通信系统中，各网元的功能以及接口(例如：N1、N2、N3、N4、N6、N11、Y1、Y2)仅为示例性的，各个网元在应用于本申请的实施例中时，并非全部功能都是必需的。核心网的全部或者部分网元可以是物理上的实体网元，也可以是虚拟化的网元，在此不做限定。
现有技术中，涉及的定位流程是针对于终端设备只接入一个PLMN下的定位技术。终端设备可以3GPP技术接入该PLMN，也可以通过非3GPP接入该PLMN。但是对于终端设备接入多个PLMN网络的定位技术并不完善。因此，终端设备在接入多个PLMN网 络时的定位问题成为目前急需完善的问题。
图3是适用于本申请实施例的移动通信系统的架构示意图。如图3所示，终端设备通过3GPP技术或者非3GPP技术接入不同的PLMN，即图3中的5G-AN可以是3GPP接入设备或非3GPP接入设备。如图3所示的网络架构中有3个PLMN。包括一个归属PLMN(home PLMN，HPLMN)和两个拜访PLMN(visited PLMN，VPLMN)，每个PLMN包括AMF、LMF、统一数据管理(unified data management，UDM)网关、移动位置中心(gateway mobile location centre，GMLC)网关。例如，对于HPLMN而言，AMF、LMF、GMLC可以分别称为归属AMF(home AMF，H AMF)、归属AMF(home LMF，H LMF)、归属AMF(home GMLC，H GMLC)。对于VPLMN而言，AMF、LMF、GMLC可以分别称为拜访AMF(visited AMF，VAMF)、拜访AMF(visited LMF，HVLMF)、拜访AMF(visited GMLC，VGMLC)。各个网元之间通过相应的接口连接。GMLC是外部定位系统(location system,LCS)客户端(例如需要定位的应用服务器)的网关节点。例如当终端设备漫游到其他城市或者区域后，就会可能有多个VPLMN为该终端设备提供服务。多个VPLMN可以包括该HPLMN，也可以不包括该HPLMN。对于多个VPLMN的场景，HPLMN中的HGMLC首选会校验目标UE(通过外部UE标识)的隐私设置，然后从HPLMN中的UDM中查询路由信息(如VGMLC的地址或者拜访AMF(visited AMF，VAMF)的地址或者拜访LMF(visited LMF，VMF)的地址)。最后将LCS客户端定位请求转发给VGMLC或者VAMF或者VLMF。
图4是适用于本申请实施例的另一个移动通信系统的架构示意图。如图4所示，终端设备通过3GPP接入或者非3GPP接入不同的PLMN。即图4中的5G-AN可以是3GPP接入设备或非3GPP接入设备。如图4所示的网络架构中为终端设备服务的有两个PLMN，即有两个服务PLMN。与图3所不同的是，图4中为两个服务PLMN包括一个VPLMN-1和HPLMN。即服务PLMN包括HPLMN和VPLMN。
应理解，随着接入技术的发展，终端设备可以接入更多的PLMN，图3或者图4的架构不对终端设备接入的PLMN数量进行限制。
下面结合图5说明本申请提供的定位方法，图5是本申请一个实施例的定位方法100的示意性交互图，该方法100可以应用在图3或者图4所示的场景中，当然也可以应用在其他通信场景中，本申请实施例在此不作限制。
如图5所示，该方法100包括：
S110，移动位置中心网关接收定位服务客户端发送的终端设备的第一定位请求；
S120，该移动位置中心网关根据该第一定位请求确定第一目标公共陆地移动网络PLMN，该第一目标PLMN用于为该终端设备提供定位服务；
S130，该移动位置中心网关向该第一目标PLMN中的第一位置管理网元LMF发送第二定位请求，该第二定位请求用于请求该第一LMF为该终端设备提供定位服务。相应的，第一LMF接收第二定位请求。
S140，第一LMF根据该第二定位请求，确定定位方法。
具体而言，在S110中，在定位服务客户端(例如LCS客户端)发起对终端的定位时，会向为该终端设备服务的移动位置中心网关发送定位请求(第一定位请求)。该第一定位请求包括该终端设备的标识，例如，可以是该终端设备的通用公共订阅标识符(generic  public subscription identifier，GPSI)或者订阅永久标识符(subscriber permanent identifier，SUPI)等。移动位置中心网关根据该第一定位请求，首先确认该终端设备的隐私设置以及定位服务客户端是否有权限定位该终端设备。其中，终端设备的隐私设置可以通过终端设备标识从UDM中获取，或者终端设备的隐私设置已经缓存或者预配置在该移动位置中心网关中。定位服务客户端的定位权限可以预先配置在该移动位置中心网关中的。
应理解，在本申请实施例中，该移动位置中心网关可以是单独的网元，例如可以是HPLMN中的HGMLC。或者，该移动位置中心网关还是部分或者全部功能集成到核心网网元，例如网络暴露功能(network exposure function，NEF)网元。或者，还可以是其他可以完成上述功能的网元等，本申请在此不作限制。
还应理解，在本申请实施例中，该LMF可以是单独的网元，或者，该LMF还是部分或者全部功能集成到核心网网元，例如AMF网元。或者，还可以是其他可以完成上述功能的网元等，本申请在此不作限制。
在S120，由于为终端设备服务的PLMN可能有多个。因此，该移动位置中心网关根据该第一定位请求，在多个为终端设备服务的PLMN中确定第一PLMN，该第一目标PLMN用于为该终端设备提供定位服务。
在S130中，在移动移动位置中心网关确定该第一PLMN后，该移动位置中心网关向该第一目标PLMN中的第一位置管理网元LMF发送第二定位请求，该第二定位请求用于请求该第一LMF为该终端设备提供定位服务。相应的，第一LMF接收第二定位请求。该第二定位请求包括该终端设备的标识。
在S140中，该第一LMF根据该第二定位请求，确定定位方法。
本申请实施例提供的定位方法，在终端设备接入多个PLMN场景时，可以实现在多PLMN场景下的终端设备的定位。明确了在多PLMN场景下终端设备的定位技术，提高了终端设备定位的效率和准确性，提高通信效率和用户体验。
应理解，在S130中，移动位置中心网关可以通过多种方式向第一目标PLMN中的第一位置管理网元LMF发送第二定位请求。例如，移动位置中心网关可以先将第二定位请求发送给第一目标PLMN中的第一GMLC,第一GMLC转发给第一目标PLMN中的第一AMF，由第一AMF发送给第一LMF。或者，移动位置中心网关可以先将第二定位请求发送给第一目标PLMN中的第一GMLC,由第一GMLC转发给第一LMF。或者，移动位置中心网关可以先将第二定位请求发送给第一目标PLMN中具有类似功能的其他网元，由其他网元转发给该第一LMF。本申请在此不作限制。
作为一个实施例，如6所示，图6是本申请另一个实施例的定位方法的示意性交互图，在S120中，该移动位置中心网关根据该第一定位请求，确定第一目标PLMN，包括：
S121：该移动位置中心网关根据该第一定位请求，确定该终端设备接入的多个PLMN；
S122：该移动位置中心网关在该多个PLMN中确定该第一目标PLMN。
具体而言在，在终端设备接入多个PLMN时，由于需要从多个PLMN中确定一个PLMN(第一目标PLMN)，该第一目标PLMN用于为该终端设备提供定位服务。因此，该移动位置中心网关首先需要根据该第一定位请求确定该终端设备接入的多个PLMN。然后，在该多个PLMN中确定该第一目标PLMN。
下面将分别说明步骤S121和S122。
在S121中，该移动位置中心网关根据该第一定位请求，确定该终端设备接入的多个PLMN，包括：
该移动位置中心网关根据该终端设备的服务接入与移动性管理网关AMF的地址数目、或者服务LMF的地址数目、或者服务移动位置中心网关GMLC的地址数目，确定该终端设备接入的多个PLMN。具体而言，由于目前对于每一个PLMN包括一个为终端设备提供服务的AMF、一个为终端设备提供服务的LMF、一个为终端设备提供服务的GMLC。因此，移动位置中心网关可以使用该终端设备的标识，通过服务化接口，从UDM网元中获取定位所需要的信息(从HPLMN获得)。即该移动位置中心网关接收UDM网元发送的该终端设备接入的服务AMF地址信息或者标识信息，或者服务LMF地址信息或者标识信息、或者服务GMLC的地址或者标识信息中的至少一个。UDM是和该移动位置中心网关同属于一个PLMN的。即移动位置中心网关可以UDM处获取服务GMLC、服务LMF、服务AMF中的任意一个或者多个的标识或者地址信息，根据服务GMLC、服务LMF、服务AMF的标识或者地址数目，确定该终端设备接入的多个PLMN。多个PLMN是为终端设备服务的PLMN。应理解，这里的服务GMLC、服务LMF、服务AMF可以理解为终端设备接入的PLMN包括的GMLC、LMF、AMF。即服务GMLC、服务LMF、服务AMF可以替换为终端设备接入的GMLC、接入的LMF、接入的AMF。例如，假设从UDM中获取3个不同的AMF的地址或者标识，则可以确定该终端设备接入了3个PLMN。
应理解，在上述的步骤S121中，由于GMLC、LMF、AMF都可以用来标识一个PLMN。因此在S121中。该移动位置中心网关还可以通过确定GMLC的标识，或者LMF的标识，或者AMF标识来唯一确定一个PLMN。即通过确定GMLC的标识，或者LMF的标识，或者AMF标识确定该终端设备接入的多个PLMN。本申请对确定多个PLMN的具体方式不作限制。
在步骤S122中，该移动位置中心网关在该多个PLMN中确定该第一目标PLMN，包括：移动位置中心网关根据终端设备的配置信息、该终端设备的接入技术类型信息、该接入技术类型对应的连接状态信息中的一个或者多个，在所述多个PLMN中确定所述第一目标PLMN。其中该配置信息包括该接入技术类型的优先级配置信息、接入技术类型对应的连接状态的优先级配置信息、多个PLMN的优先级配置信息中得一种或者多种。
具体的，该移动位置中心网关可以根据如下的几种方式确定第一目标PLMN：
该移动位置中心网关根据该接入技术类型优先级配置信息和接入技术类型信息，在该多个PLMN中确定该第一目标PLMN，每一个PLMN对应不同的接入技术类型；或者
该移动位置中心网关根据该多个PLMN的优先级配置信息，在该多个PLMN中确定该第一目标PLMN；或者
该移动位置中心网关在该多个PLMN中随机确定该第一目标PLMN；或者
该移动位置中心网关根据该终端设备该接入技术类型的优先级配置信息、接入技术类型对应的连接状态的优先级配置信息、该接入技术类型信息，以及该接入技术类型对应的连接状态信息，在该多个PLMN中确定该第一目标PLMN。
具体而言，移动位置中心网关确定多个PLMN后，需要从多个PLMN中确定该第一目标PLMN，该第一目标PLMN用于为该终端设备提供定位服务。可有如下的几种实现方式：
一种可能的实现方式为：该移动位置中心网关根据该终端设备的接入技术类型优先级配置信息(包括在该配置信息中)和接入技术类型信息，在该多个PLMN中确定该第一目标PLMN。每一个PLMN对应不同的接入技术类型。由于一个PLMN对应一种或者多种接入类型，一种接入类型对应多种连接状态。每一个PLMN对应不同的接入技术类型。因此，该移动位置中心网关可以根据多个PLMN对应的接入技术类型的优先级配置信息和多个PLMN对应接入技术类型信息，首先根据接入技术类型的优先级从多个接入技术类型中确定出第一接入技术类型，然后根据与第一接入技术类型对应的PLMN，确定出第一目标PLMN。接入技术类型的优先级配置信息可以预先存储在该移动位置中心网关中，也可以是从定位服务客户端获取的。接入技术类型可以是预先存储在该移动位置中心网关中，也可以是从UDM中获取的。
该终端设备的接入技术类型至少存在如下三种可能：1、终端设备通过3GPP技术接入；2、终端设备通过非3GPP技术接入；3、终端设备通过3GPP技术接入和通过非3GPP技术接入。接入技术类型的优先级配置信息可以是3GPP技术接入优先或者非3GPP技术接入等。3GPP技术接入类型可以包括卫星接入和基站接入等。非3GPP技术接入可以包括有线接和无线接入等。
在本申请的实施例中，连接状态是针对接入类型而言的，主要分为空闲态(idle)和连接态(connected)。举个例子说明。该终端设备的连接状态包括该终端设备与第一接入技术类型(例如，3GPP接入类型)的第一接入点(例如，NGRAN)之间的第一链路的状态，或者该终端设备与第二接入技术类型(例如，非3GPP接入类型)的第二接入点(例如，N3IWF)之间的第二链路的状态。
另一种可能的实现方式为：该移动位置中心网关根据该多个PLMN的优先级配置信息，在该多个PLMN中确定该第一目标PLMN。多个PLMN的优先级配置信息可以包括在上述的配置信息中。除了上述的利用接入技术类型确定该第一目标PLMN之外，该移动位置中心网关还可以根据多个PLMN优先级配置信息，在该多个PLMN中确定该第一目标PLMN。例如，当HPLMN和VPLMN同时为终端设备提供服务时，VPLMN优先级最高。多个PLMN的优先级配置信息可以预先存储在该移动位置中心网关中，也可以是从定位服务客户端获取的。
另一种可能的实现方式为：该移动位置中心网关根据该接入技术类型的优先级配置信息、接入技术类型对应的连接状态的优先级配置信息、终端设备的接入技术类型信息、接入技术类型对应的连接状态信息，在该多个PLMN中确定该第一目标PLMN。对于通过接入技术类型还不能确定该第一目标PLMN的情况，例如，不同的PLMN可能对应同一种接入类型。在这种情况下，移动位置中心网关可以根据接入技术类型的优先级配置信息、该接入技术类型对应的连接状态信息，该接入技术类型信息以及连接状态的优先级配置信息，在多个PLMN中确定该第一目标PLMN。具体的，可以先根据技术类型的优先级配置信息和接入技术类型信息，确定出候选的PLMN的范围，候选的多个PLMN可以对应相同的接入技术类型。然后在候选的PLMN中，根据接入技术类型对应的连接状态信息和连接状态的优先级配置信息，进一步的确定出第一目标PLMN。连接状态的优先级配置信息可以是连接态优先等。
另一种可能的实现方式为：该移动位置中心网关在该多个PLMN中随机确定一个 PLMN为该第一目标PLMN。
应理解，上述的配置信息还可以包括上述的几种确定第一目标PLMN的方式的优先级配置信息。例如，随机确定第一目标PLMN的方式的优先级最低。本申请在此不作限制。
应理解，在本申请实施例中，上述的几种从多个PLMN中确定该第一目标PLMN的方式可以联合起来使用，即可以使用上述中的任意一种或者多种综合确定第一目标PLMN。例如：在通过接入技术类型的优先级配置信息、接入类型信息以及连接状态信息都无法确认第一目标PLMN，可以采用随机选择的方式确定第一目标PLMN。本申请实施例在此不作限制。
通过上述的几种方式在该多个PLMN中确定该第一目标PLMN，可以提高确定该第一目标PLMN的准确性和效率，可以更加快速和准确的确定出第一目标PLMN。节省通信资源，节省定位时间，进一步的提高用户体验。
在S140中，第一目标PLMN中第一LMF根据该第二定位请求，确定定位方法。由于该第一LMF在确定定位方法时不仅会考虑精度、时延等要求，还会考虑终端设备当前的接入技术类型，即在其他因素(精度、时延等)相同的情况下，若终端设备的接入类型不同则可能导致第一LMF确定出的终端设备的定位方法不同。因此该第二定位请求还可以包括上述的接入技术类型的优先级配置信息、该接入技术类型对应的连接状态信息，该接入技术类型信息、连接状态的优先级配置信息、终端设备的标识中的任意一个或者多个。
作为一个实施例，如7所示，图7是本申请另一个实施例的定位方法的示意性交互图，该方法100还包括：
S150，第一LMF根据定位方法，确定第一定位结果，对于步骤S150，第一LMF根据定位方法，确定第一定位结果的具体过程可以采用现有的根据定位方法确定定位结果的过程。例如，可以参考申请号为201810318534.7的中国专利申请中介绍的确定定位结果的方法，本申请对根据定位方法，确定第一定位结果的具体过程不作限制。
S160，该移动位置中心网关接收该第一LMF发送的该终端设备的第一定位结果；
S170，在该第一定位结果不满足定位要求的情况下，该移动位置中心网关在多个PLMN中确定第二目标PLMN，并向第二目标PLMN中的第二LMF发送第三定位请求，该第三定位请求用于请求该第二目标PLMN中的第二LMF为该终端设备提供定位服务。相应的，第二目标PLMN中的第二LMF接收该第三定位请求。
S171，第二LMF根据该第三定位请求，确定第二定位结果。并向该移动位置中心网关发送该第二定位结果。
S172，该移动位置中心网关接收该第二LMF发送的该终端设备的第二定位结果。
具体而言，该第一LMF根据定位方法，确定第一定位结果后，将该第一定位结果后发送给该移动位置中心网关。该移动位置中心网关会判断该第一定位结果是否满足要求。该第一定位结果包括终端设备的位置信息(根据使用定位方法的不同，位置信息不同)、定位是否成功的指示、采用的定位方法等。例如，可以通过定位结果中的是否定位成功的指示和与定位结果对应的定位精度确定定位结果是否满足定位要求。该第一定位结果中带有第一LMF采用的定位方法，并且定位精度可以由采用的定位方法体现。即定位方法确定后，采用该定位方法得到的定位结果的精度也就确定了。在第一定位结果不满足定位要 求的情况下，该移动位置中心网关向第二目标PLMN中的第二LMF发送第三定位请求，该第三定位请求用于请求该第二目标PLMN中的第二LMF为该终端设备提供定位服务。即请求第二LMF确定定位结果，第二LMF确定第二定位结果，并将定位结果送给该移动位置中心网关。
通过上述的方式，在第一LMF的定位结果不准确的情况下，可以获取第二LMF的定位结果，可以使得该终端设备的定位结果更加准确，提高定位的精度和准确性。
应理解，在第一定位结果满足定位要求的情况下，该移动位置中心可以直接向定位服务客户端发送该第一定位结果，不用再确定第二目标PLMN，即定位流程结束。
还应理解，该移动位置中心网关在多个PLMN中确定第二目标PLMN的过程与上述的确定第一目标PLMN的过程类似，相应的描述可以参考上述确定第一目标PLMN的相关描述。为了简洁，这里不再赘述。
还应理解，该移动位置中心网关向第二目标PLMN中的第二LMF发送第三定位请求的过程和上述的该移动位置中心网关向第一LMF发送第二定位请求的过程类似，相应的描述可以参考上述向第一LMF发送第二定位请求的相关描述。为了简洁，这里不再赘述。
作为一个实施例，如8所示，图8是本申请另一个实施例的定位方法的示意性交互图，该方法100还包括：
S173，该移动位置中心网关根据该第一定位结果和该第二定位结果确定该终端设备的目标定位结果；
S174，该移动位置中心网关向该定位服务客户端发送该目标定位结果。
具体而言，在该移动位置中心网关接收到该第一定位结果和该第二定位结果后，可以根据该第一定位结果和该第二定位结果确定该终端设备的目标定位结果，例如，该目标定位结果可以是第一定位结果和该第二定位结果中定位精度较高的定位结果。然后将该目标定位结果发送给定位服务客户端，即定位流程结束。
应理解，如果该第二定位结果还是不满足定位要求，该移动位置中心网关还可以继续确定第三目标PLMN，然后向第三目标PLMN的第三LMF发送定位请求，并接收第三LMF发送的第三定位结果。如果第三定位结果满足要求，可以将该第三定位结果发送给定位服务客户端。如果第三定位结果不满足要求，可以在第一定位结果、第二定位结果和第三定位结果中选择定位精度最高的定位结果作为目标定位结果。或者，该移动位置中心网关还可以继续确定第四目标PLMN，然后向第四目标PLMN的第四LMF发送定位请求。并接收第四LMF发送的第四定位结果，根据这四个定位结果确定最终的目标定位结果。即移动位置中心网关可以确定多个目标PLMN。多个目标PLMN可以重复执行确定定位结果并上报定位结果的处理流程。本申请实施例在此不作限制。
通过上述的方式，在第一LMF的定位结果和第二LMF的定位结果中确定出精度最好的目标定位结果。或者还可以在更多个LMF确定的定位结果中确定出精度最好的目标定位结果，使得定位结果更加准确，提高定位的精确度。
作为一个实施例，除了上述的在该多个PLMN中确定该第一目标PLMN的方式外，在S122中，该移动位置中心网关在该多个PLMN中确定该第一目标PLMN，包括以下步骤：
步骤1：该移动位置中心网关确定该终端设备接入的多个PLMN；
步骤2：该移动位置中心网关分别向该多个PLMN中的LMF发送第一指示信息，该第一指示信息用于指示该多个PLMN中的LMF确定定位方法；
步骤3：该移动位置中心网关分别接收该多个PLMN中的LMF发送的定位方法；
步骤4：该移动位置中心网关根据接收到的该定位方法确定该第一目标PLMN。
具体而言，步骤1和前述的S121类似，相应的描述可以参考上述确定第一目标PLMN的过程。为了简洁，这里不再赘述。对于步骤2，在该移动位置中心网关确定了该终端设备接入的多个PLMN后，可以向该多个PLMN中的每个LMF分别发送第一指示信息。该第一指示信息用于指示该多个PLMN中的每个LMF确定定位方法。该第一指示信息可以包含定位要求、上述的配置信息等。LMF接收到第一指示信息后，自行确定使用的接入技术类型和定位方法。可选的，也可以向该多个PLMN中的部分LMF分别发送第一指示信息。相应的。多个PLMN中的每个LMF根据该第一指示信息，分别确定定位方法，并将确定的定位方法发送给该移动位置中心网关。即步骤3：该移动位置中心网关分别接收该多个PLMN中的LMF发送的该定位方法。应理解，每个PLMN中的LMF可以只确定一种定位方法，也可以确定多种定位方法。对于步骤4，该移动位置中心网关根据接收到的多个定位方法，确定该第一目标PLMN。
对于步骤4：该移动位置中心网关根据接收到的该定位方法确定该第一目标PLMN，包括：
该移动位置中心网关根据该定位方法的定位精度，确定第一定位方法；
该移动位置中心网关根据该第一定位方法，确定该第一目标PLMN。
具体而言，由于每一种定位方法都有对应的定位精度，在定位方法确定后，其定位精度也就确定了。因此，该移动位置中心网关根据多个定位方法对应的定位精度，确定第一定位方法，例如该第一定位方法可以是该多个定位方法中定位精度最高的定位方法。在确定了第一定位方法，便可以根据该第一定位方法对应的第一LMF，确定第一LMF以及确定第一LMF所属的第一目标PLMN。该移动位置中心网关可以向第一LMF发送指示信息，用于指示第一LMF执行该定位方法。该指示信息可以包括该第二定位请求中。
通过上述的几种方式在该多个PLMN中确定该第一目标PLMN，可以提高确定该第一目标PLMN的准确性和效率，可以更加快速和准确的确定出第一目标PLMN。节省通信资源，节省定位时间，进一步的提高用户体验。
可选的，该移动位置中心网关通过该定位方法的定位精度，确定第一定位方法，然后根据该第一定位方法确定该第一目标PLMN后，该移动位置中心网关还可以向其他PLMN发送指示信息，该指示信息用于指示其他PLMN不执行各自确定的定位方法。即通知其他PLMN包括的LMF不用执行确定的定位方法。可选的，该移动位置中心也可以通过隐式的指示通知其他PLMN包括的LMF不执行确定的定位方法。例如，在每个LMF中都可以设置一个定时器，如果在定时器超时前LMF收到上述的第二定位请求或者用于指示执行定位方法的指示信息，则执行定位方法。如果LMF没有收到该定位请求或者该指示信息，则不执行定位方法。
作为一个实施例，如9所示，图9是本申请另一个实施例的定位方法的示意性交互图，该方法100还包括：
S111，该移动位置中心网关接收统一管理网元发送的该终端设备接入的服务AMF地 址信息，服务LMF地址信息、或者服务GMLC的地址信息中的至少一个。移动位置中心网关根据该服务AMF地址信息，服务LMF地址信息、或者服务GMLC的地址信息中的至少一个，确定该终端设备接入的多个PLMN。终端设备接入的多个PLMN可以包括为终端设备服务的多个服务PLMN。多个服务PLMN可以包括终端设备的多个VPLMN，还可以包括终端设备的HPLMN。统一管理网元可以是UDM网元。确定该终端设备接入的多个PLMN具体的过程可以参考上述的确定该终端设备接入的多个PLMN过程，为了简洁，这里不再赘述。

作为一种实现方式，该移动位置中心网关为该终端设备的归属公共陆地移动网络HPLMN的移动位置中心网关GMLC，即该移动位置中心网关为HGMLC。该第一目标PLMN为该终端设备的拜访公共陆地移动网络VPLMN。或者，在该终端设备的拜访公共陆地移动网络VPLMN有多个时，该第一目标PLMN为多个VPLMN中的一个。或者，在该终端设备的服务PLMN包括一个或者多个VPLMN以及HPLMN的情况下，该第一目标PLMN也可能是该终端设备的HPLMN。即为该终端设备提供定位服务可以是该HPLMN。本申请实施例在此不作限制。
作为一个实施例。该第二定位请求还包括：该第一目标PLMN对应的接入技术类型信息、该接入技术类型对应的连接状态信息和接入技术类型和该配置信息中的至少一个。

对于步骤S142，该移动位置中心网关在接收到该定位方法后，会判断该定位方法是否满足定位要求。例如，可以根据该定位方法对应的定位精度，确定该定位方法是否满足定位要求。如果该定位方法满足定位要求，会向第一LMF发送第二指示信息，该第二指示信息用于指示第一LMF执行该定位方法。或者，如果该定位方法不满足定位要，则该第二指示信息用于指示第一LMF不执行该定位方法。相应的，该第一LMF接收该第二指示信息。
可选的，除了通过上述的通过指示信息的方式通知该第一LMF执行或者不执行该第 定位方法。也可以通过隐式的指示第一LMF执行或者不执行确定的定位方法。例如，在第一LMF可以设置一个定时器，如果在定时器超时前第一LMF收到上述的第二指示信息则执行该定位方法，如果在定时器超时前第一LMF没有收到上述的指示信息，则不执行该定位方法。
在该第二指示信息指示第一LMF执行该定位方法的情况下，第一LMF便可以执行步骤上述的步骤S150以及步骤S160：根据定位方法，确定第一定位结果，以及将该第一定位结果发送给移动位置中心网关。
作为一种实现方式：该第二定位请求还包括该终端设备的配置信息时，在步骤S140中，第一LMF根据该第二定位请求，确定定位方法，包括：

具体而言，在该第二定位请求还包括该终端设备的配置信息。该配置信息可以包括接入技术类型的优先级配置信息、接入技术类型对应的连接状态的优先级配置信息、多个PLMN的优先级配置信息中的一种或者多种。第一LMF可以根据该配置信息和接入技术类型信息，确定接入技术类型。如上所述，由于一个LMF可能对应多种接入类型，而每一种接入类型可以对应一种或者多种连接状态。因此，第一LMF可以根据该第二定位请求包括的接入类型的优先级配置信息，结合接入技术类型信息，确定该终端设备的接入技术类型。然后根据该接入技术类型，确定与该接入技术类型对应的定位方法。
可选的，第一LMF还可以利用接入技术类型信息、连接状态的信息和连接状态的优先级配置信息确定该定位方法，本申请在此不作限制。
应理解，第二定位请求还可以包括上述的接入技术类型信息、以及连接状态信息中的任意一种或者多种。该第二定位请求还可以包括定位要求等。本申请在此不作限制。
作为另一种实现方式：在该第二定位请求还包括该终端设备的接入技术类型信息时，在步骤S140中，第一LMF根据该第二定位请求，确定定位方法，包括：
步骤1：该LMF根据该接入技术类型，确定该定位方法。
具体而言，在该第二定位请求还包括该终端设备的接入技术类型信息时，即该移动位置中心网关已经确定好了第一LMF所用的接入技术类型。第一LMF可以直接根据该接入技术类型，确定定位方法。可选的，第一LMF还可以利用接入技术类型信息、连接状态的信息和连接状态的优先级配置信息确定该定位方法，本申请在此不作限制

S210，移动位置中心网关接收定位服务客户端发送的终端设备的第四定位请求，该第四定位请求包括该终端设备的标识；
S220，该移动位置中心网关根据该第四定位请求，确定该终端设备的第一接入技术类型；
S230，该移动位置中心网关根据该第一接入类型，向该第一接入类型对应的第一LMF发送第五定位请求，该第五定位请求用于请求该第一LMF为该终端设备提供定位服务。相应的，该第一LMF接收该第五定位请求。
具体而言，在S210中，在定位服务客户端(例如LCS客户端)发起对终端的定位时，会向为该终端设备服务的移动位置中心网关发送定位请求(第四定位请求)。该第四定位请求包括该终端设备的标识，例如，可以是该终端设备的GPSI或者SUPI等。移动位置中心网关根据该第四定位请求，首先确认该终端设备的隐私设置以及定位服务客户端是否有权限定位该终端设备。其中，终端设备的隐私设置可以通过终端设备标识从UDM中获取，或者终端设备的隐私设置已经缓存或者预配置在该移动位置中心网关中。定位服务客户端的定位权限可以预先配置在该移动位置中心网关中的。
在S220和S230中，该移动位置中心网关根据该第四定位请求，确定该终端设备的第一接入技术类型。具体的，由于目前对于每一个PLMN包括一个为终端设备提供服务的AMF、一个为终端设备提供服务的LMF、一个为终端设备提供服务的GMLC，一个LMF对应一种或者多种接入技术类型。因此，在终端设备接入为终端设备服务的多个PLMN时(接入多个LMF时)，需要从多个PLMN中(即多个LMF中)确定为该终端设备提供定位服务的第一PLMN(第一LMF)时，可以通过确定接入技术类型的方式确定第一PLMN(即第一LMF)。该移动位置中心网关可以在多个LMF对应的多种接入技术类型中确定第一接入技术类型。然后根据与该第一接入类型对应的PLMN，确定第一PLMN，该第一PLMN是用于为该终端设备提供定位服务的。确定了第一PLMN后，便可以确定该第一PLMN中的第一LMF。即该移动位置中心网关可以在多个LMF对应的多种接入技术类型中确定第一接入技术类型。然后根据与该第一接入类型，便可以确定该第一LMF。在确定了第一LMF后，该移动位置中心网关便可以向该第一接入类型对应的第一LMF发送第五定位请求，该第五定位请求用于请求该第一LMF为该终端设备提供定位服务。该第五定位请求包括该终端设备的标识。
本申请实施例提供的定位方法，在终端设备接入多个LMF场景时，可以利用接入技术类型确定为终端设备提供服务的LMF，可以实现在LMF场景下的终端设备的定位。明确了在多LMF场景下终端设备的定位技术，提高通信效率和用户体验。
作为一个实施例，如图13所示，在S220中，该移动位置中心网关确定该终端设备的第一接入技术类型，包括：
S221，该移动位置中心网关根据该终端设备的配置信息、终端设备的接入技术类型信息和该接入技术类型对应的连接状态信息，确定该第一接入技术类型。
具体而言，由于一个为终端设备服务的PLMN对应一种或者多种接入类型，一种接入类型对应多种连接状态。每一个PLMN对应不同的接入技术类型。因此，移动位置中心网关可以根据配置信息、终端设备的接入技术类型信息和该接入技术类型对应的连接状态信息，确定该第一接入技术类型。该配置信息可以包括接入技术类型的优先级配置信息、接入技术类型对应的连接状态的优先级配置信息、多个PLMN的优先级配置信息中的一种或者多种。移动位置中心网关可以根据接入技术类型的优先级配置信息、该接入技术类型对应的连接状态信息以及该接入技术类型信息。从多个接入技术类型中确定出第一接入技术类型。具体的，可以根据接入技术类型的优先级配置信息和多个接入技术类型，确定出第一接入技术类型，该第一接入技术类型唯一对应一个第一LMF。可以提高确定该第一LMF的准确性和效率，可以更加快速和准确的确定出第一LMF。节省通信资源，节省定位时间，进一步的提高用户体验。
可选的，如果根据技术类型的优先级配置信息和多个接入技术类型，确定出的接入技术类型对应多个不同的LMF。即根据技术类型的优先级配置信息和多个接入技术类型不能唯一确定LMF。该移动位置中心网关还可以进一步的结合该接入技术类型对应的连接状态信息，以及连接状态的优先级配置信息，进一步的根据连接状态确定出第一接入技术类型，即确定该第一LMF。
应理解，该配置信息可以预先存储在该移动位置中心网关中，也可以是从定位服务客户端获取的。接入技术类型可以是预先存储在该移动位置中心网关中，也可以是从UDM中获取的。连接状态可以是预先存储在该移动位置中心网关中，也可以是从UDM中获取的。
还应理解，该移动位置中心网关还可以从多种接入类型中随机确定第一接入技术类型，然后向该第一接入类型对应的第一LMF发送第五定位请求。本申请实施例在此不作限制。
作为一个实施例，如图14所示，该方200还包括：
S240，该第一LMF根据该第五定位请求，确定第一定位结果。
S250，该移动位置中心网关接收该第一LMF发送的该终端设备的第一定位结果；

下面将结合具体的例子说明书本申请提供的定位方法的具体流程。
图16是本申请一个实施例的定位方法300的示意性流程图。
如图16所示，该方法300包括：
S301，外部LCS客户端向移动位置中心网关(HPLMN中的HGMLC)发送针对终端设备的第一定位请求，该第一定位请求包括终端设备的标识，如目标终端设备的GPSI或者SUPI，HGMLC首先确认该目标终端设备的隐私设置以及LCS客户端是否有权限定位该终端设备。其中，终端设备的隐私设置可以通过终端设备标识从HPLMN中的UDM中获取或者已经缓存或者预配置在HGMLC中。LCS客户端定位权限是预先配置在HGMLC中的。
S302，HGMLC使用终端设备的标识信息(GPSI或者SUPI等)，通过服务化接口(例如，Nudm_UE Context Management_Get)，向UDM获取定位所需的信息，例如，包括服务AMF(VAMF)的地址、服务LMF(VLMF)地址或者服务GMLC(VGMLC)的地址等信息。
S303，针对该终端设备的每一种接入技术类型，UDM反馈定位信息，该定位信息包括VAMF地址。也可能包括VGMLC地址或者VLMF地址。如果HGMLC需要获取接入类型和/或连接状态(例如HGMLC需要根据接入类型优先级配置和/或连接状态的优先级配置确定目标PLMN，或者HGMLC需要传输这些信息)，UDM则同时会反馈接入类型和/或连接状态。
S304，当HGMLC根据UDM返回的VAMF等网元的地址数目，发现终端设备接入了不同PLMN。则HGMLC根据接入技术类型的优先级配置和/或连接状态的优先级配置，选择一个PLMN(第一目标PLMN)进行定位。或者，HGMLC也可以随机选择一个PLMN(第一目标PLMN)进行定位。该第一目标PLMN用于为该终端设备提供定位服务。接入技术类型的优先级配置可以预先配置在HGMLC或者从LCS客户端的发送的第一定位请求中获取。例如，可能是3GPP接入优先或者N3GPP接入优先。接入类型指终端设备接入5G核心网采用的技术，如3GPP接入或者N3GPP接入。N3GPP接入又包含可信N3GPP接入和非可信N3GPP接入。连接状态则是针对特定接入类型而言的，分为空闲态和连接态。
S305，在HGMLC确定了第一目标PLMN(VPLMN-1)后，会向第一目标PLMN中的GMLC(VGMLC-1)发送第二定位请求。该第二定位请求中可能包括接入类型和/或连接状态等信息，也可能包括第一目标PLMN中的VAMF-1的地址，VLMF-1的地址，该终端设备的标识等信息。
S306，VGMLC-1将第二定位请求进一步转发给VLMF-1网元。根据方案的不同，VGMLC-1可能会间接通过VAMF-1转发给VLMF-1，最终VLMF-1接收到该第二定位请 求。或者，VGMLC-1也可以将第二定位请求直接发给VLMF-1。
S307，如果VLMF-1还未支持的获取终端设备支持的定位能力。VLMF-1需要先与终端设备进行交互以获取终端设备支持的定位能力。定位能力主要包括：终端设备支持的定位方法，终端设备支持的定位设备(例如是否含有全球定位系统(Global Positioning System，GPS)模块)等。
S308，VLMF-1根据终端设备支持的定位能力，网络支持的定位能力(与终端设备支持的定位能力类似)，第二定位请求中包含的定位要求，接入技术类型以及连接状态等信息确定定位方法和转发路径。
S309，VLMF-1执行定位方法。
S310，VLMF-1获取第一定位结果。
S311，VLMF-1将第一定位结果回给VGMLC-1。VGMLC-1将第一定位结果最后返回给HGMLC。
S312，当HGMLC接收到第一定位结果后，根据第一定位结果中包括的定位是否成功的指示信息以及定位精度，确定该第一定位结果是否满足定位要求。定位要求主要包括精度和时延等。第一定位结果的不同情况的处理如下:
(a)定位成功，且精度满足要求，则直接第一返回结果给LCS客户端，定位结束；
(b)定位成功，但精度不满足要求，执行S313；
(c)定位失败，执行S313；
S313，HGMLC确定第二目标PLMN，向第二目标PLMN转发定位请求，并接收VLMF-2发送的第二定位结果。即针对于第二目标PLMN，执行步骤304至步骤S311步。
S314，HGMLC比较第一定位结果和第二定位结果(第二目标PLMN确定的定位结果)。确定出精度较高的目标定位结果。如果第一定位结果和第二定位结果都不满足定位要求，则将第一定位结果和第二定位结果作为目标定位结果。
S315，HGMLC向给LCS客户端反馈目标定位结果。
应理解，上述方案同样适用于单PLMN的场景，在S304中，当HGMLC检测到仅有单个PLMN服务于终端设备，这是服务的PLMN可能是上述的VPLMN-1，也可能是HPLMN，这时HGMLC会将上述的第二定位请求转发给VPLMN-1中的VAMF-1或者VLMF-1，或者转发给HPLMN中的HAMF或者HLMF。后续的处理步骤为S306-S311以及最后的S315。
还应理解，上述方法300中的技术方案同样适用于VPLMN和HPLMN同时为终端设备服务的场景中。即上述的方法300中的VLMF-1、VAMF-1可以替换成HLMF、HAMF。即为终端设备服务的PLMN包括VPLMN和HPLMN的场景，在这种情况下，上述的第一目标PLMN或者第二目标PLMN还可能是HPLMN。本申请在此不作限制。
还应理解，方法300以两个VPLMN分别进行定位为例进行说明。但是上述的技术方案还可以应用在更多个VPLMN分别进行定位的场景中，例如，上述的第一定位结果和第二定位结果如果都不满足定位要求，则可以继续确定第二目标PLMN(VPLMN-3)，并获取VPLMN-3反馈的第三定位结果。然后在三个定位结果中确定目标定位结果。本申请在此不作限制。

S408，VLMF-1和VLMF-2分别根据终端设备支持的定位能力，网络支持的定位能力(与终端设备支持的定位能力类似)，第二定位请求中包含的定位要求和指示信息，接入技术类型以及连接状态等信息确定定位方法和转发路径，确定定位方法后暂不执行定位方法。
S409，VLMF-1和VLMF-2分别向VGMLC-1和VGMLC-2返回各自的定位方法，VGMLC-1和VGMLC-2分别将定位方法返回给HGMLC。
S410，H-GMLC会根据两个PLMN返回的定位方法和精度，选择一个目标PLMN(例如VPLMN-2)执行定位。如果首先接收的定位方法已经满足定位需要，则立即向满足定位需要的定位方法对应的LMF发送执行指令。H-GMLC可以显示的通过指示信息的方式 发送该执行指令。可选的，HGMLC还可以显式向另外一个PLMN(VPLMN-1)发送指令取消定位。或者，两个LMF可以利用定时器是否超时的方式确定是否执行定位方法。
