以图1a或图1b所示的通信系统应用于如图2所示的5G网络为例，如图4所示，为本申请实施例提供的一种定位请求处理方法，该定位请求处理方法包括如下步骤：
S401、第一设备向AMF网元发送请求消息。相应的，AMF网元接收来自第一设备的请求消息。
其中，请求消息用于请求第一终端设备的位置信息，即第一终端设备可以理解为定位对象。
可选的，第一设备可以为第一终端设备位置信息的需求方(以下简称需求方)与AMF网元之间，用于选择AMF网元处理定位请求的网元，此时可以认为需求方与AMF网元之间通过第一设备的转发进行通信。示例性的，第一设备可以为GMLC或者NEF网元，该需求方例如可以为第三方应用服务器或者AF网元。该情况下，在该步骤S401之前，第一设备还接收需求方的用于请求第一终端设备的位置信息的消息。或者，第一设备也可以为第一终端设备位置信息的需求方，本申请实施例对此不做具体限定。
其中，该请求消息可以包括第一终端设备的标识。可选的，第一终端设备的标识可以为第一终端设备的用户永久标识(subscription permanent identifier，SUPI)，或者也可以为一般公共订阅标识(generic public subscription identifier，GPSI)。
可选的，该请求消息还可以包括定位精度信息、第一终端设备位置信息的需求方的位置信息。
可选的，定位精度信息表示需求方对第一终端设备的位置信息的精度要求，例如，当该定位精度信息为1米时，表示需求方要求返回的第一终端设备的位置信息指示的位置与第一终端设备实际所处的位置之间的欧式距离小于或等于1米；当定位精度信息为10米时，表示需求方要求返回的第一终端设备的位置信息指示的位置与第一终端设备实际所处的位置之间的欧式距离小于或等于10米。
可选的，需求方的位置信息表示需求方的位置，其可以为需求方在某个位置系统(例如，全球定位系统(global positioning system，GPS)或北斗卫星系统)中的地理位置坐标；或者，也可以为需求方在移动通信网络中的位置，例如，小区标识(cell identifier)或跟踪区标识(tracking area identifier，TAI)等。
S402、AMF网元根据请求消息向LMF网元发送第一消息。相应的，LMF网元接收来自AMF网元的第一消息。
其中，第一消息用于触发LMF网元通过用户面定位获取第一终端设备的位置信息。
其中，第一消息包括第一终端设备的标识。可选的，第一消息还可以包括定位精度信息、第一终端设备位置信息的需求方的位置信息，可参考上述步骤S401中的相关说明，在此不再赘述。
可选的，AMF网元接收到请求消息后，可以根据自身状态确定其是否可以及时进行定位业务的相关传输(例如转发定位业务的数据包)，当AMF网元确定无法及时进行定位业务的相关传输时，向LMF网元发送该第一消息，以触发LMF网元通过用户面定位获取第一终端设备的位置信息。
示例性的，AMF网元确定无法及时进行定位业务的相关传输，可以为：AMF网 元检测该AMF网元的负载量是否大于第一阈值，当该AMF网元的负载量大于第一阈值时，AMF网元确定该AMF网元处于拥塞状态，从而确定无法及时进行定位业务的相关传输。
或者，可选的，AMF网元接收到请求消息后，可以不进行自身状态的判断，而向LMF网元发送第一消息，以触发LMF网元通过用户面定位获取第一终端设备的位置信息，从而减轻AMF网元的负载量，本申请实施例对此不做具体限定。
可选的，第一消息可以通过多种方式触发LMF网元通过用户面定位获取第一终端设备的位置信息，示例性的：
在一种可能的实现方式中，第一消息的消息名称或者消息类型可以作为一种触发条件，该消息名称或该类消息可以触发LMF网元通过用户面定位获取第一终端设备的位置信息。也就是说，具有特定名称或特定类型的消息可以触发LMF网元进行用户面定位。
在另一种可能的实现方式中，第一消息可以包括第一指示信息，该第一指示信息指示LMF网元通过用户面定位获取第一终端设备的位置信息，即第一消息通过第一指示信息显式触发LMF网元通过用户面定位获取第一终端设备的位置信息。
可选的，在该实现方式中，第一指示信息可以由第一消息中的一个比特表示，当该比特的取值为“1”或为“0”时，表示第一指示信息指示LMF网元通过用户面定位获取第一终端设备的位置信息。
在又一种可能的实现方式中，当AMF网元确定其处于拥塞状态时，第一消息可以包括第二指示信息，该第二指示信息可以指示AMF网元处于拥塞状态，以触发该LMF网元通过用户面定位获取第一终端设备的位置信息。也就是说，第一消息通过第二指示信息指示AMF网元处于拥塞状态，从而间接触发LMF网元通过用户面定位获取第一终端设备的位置信息。
示例性的，第二指示信息可以由第一消息中的一个比特表示，当该比特的取值为“1”或为“0”时，表示AMF网元处于拥塞状态，从而触发LMF网元通过用户面定位获取第一终端设备的位置信息。
S403、LMF网元根据第一消息向第一终端设备发送第二消息。相应的，第一终端设备接收来自LMF网元的第二消息。
其中，第二消息用于指示第一终端设备上报定位数据，该定位数据用于LMF网元获取第一终端设备的位置信息。该定位数据也可以称为测量数据(measurement data)，二者可以相互替换，本申请实施例对此不做具体限定。
可选的，LMF网元接收来自AMF网元的第一消息后，可以选择合适的位置计算方法，之后，确定该位置计算方法所需的由第一终端设备提供的定位数据，并向第一终端设备发送该第二消息。
其中，LMF网元根据第一消息，通过第一终端设备的协议数据单元(protocol data unit，PDU)会话向第一终端设备发送第二消息。相应的，第一终端设备通过该第一终端设备的PDU会话接收来自LMF网元的第二消息。
可选的，LMF网元根据第一消息通过第一终端设备的PDU会话向第一终端设备发送第二消息，可以包括：LMF网元通过第一终端设备的PDU会话对应的用户面网 元(以UPF网元为例)向第一终端设备发送第二消息，该第二消息的目的地址为第一终端设备的IP地址。相应的，第一终端设备通过该第一终端设备的PDU会话接收来自LMF网元的第二消息，可以包括：第一终端设备通过该第一终端设备的PDU会话对应的用户面网元接收来自LMF网元的第二消息。
也就是说，该第二消息的传输路径可以为“LMF网元-UPF网元-gNB-第一终端设备”，其中，传输路径“UPF网元-gNB-第一终端设备”为建立第一终端设备的PDU会话时建立的传输路径，其也可以称为第一终端设备的用户面传输路径。
其中，“通过第一终端设备的PDU会话”也可以理解为“通过第一终端设备的用户面传输路径”，此时，相应的，“通过第一终端设备的PDU会话对应的用户面网元”可以理解为“通过第一终端设备的用户面传输路径中的用户面网元”，可以相互替换，本申请实施例对此不做具体限定。
基于该方案，在定位业务中，LMF网元与被定位的终端设备可以通过该被定位终端设备的用户面传输路径进行交互，可以避免通过AMF网元的转发即控制面传输路径交互，从而可以避免由于AMF网元无法及时转发定位业务的数据包而导致的定位业务的响应时间过长，降低定位业务的响应时间或降低发生定位业务中断的概率。
可选的，在本申请实施例的一种实施场景下，该定位请求处理方法还包括如下步骤S404-S406：
S404、第一终端设备获取定位数据。
其中，第一终端设备接收第二消息后，可以根据第二消息，获取定位数据。
可选的，第一终端设备获取定位数据，可以为：第一终端设备按照LMF网元的要求进行收集、测量(例如测量第一终端设备的当前服务小区的相邻小区的信号质量)，得到定位数据。
S405、第一终端设备向LMF网元发送定位数据。相应的，LMF网元接收来自第一终端设备的定位数据。
其中，第一终端设备同样可以通过第一终端设备的PDU会话向LMF网元发送定位数据。相应的，LMF网元通过第一终端设备的PDU会话接收来自第一终端设备的定位数据。
