具体实施方式
为了更好的理解本申请实施例公开的一种位置获取方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1a，图1a为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备、一个第一终端设备和一个第二终端设备，图1a所示的设备数量和形态用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的第一终端设备，两个或两个以上的第二终端设备。图1a所示的通信系统以包括一个网络设备101、一个第一终端设备102和一个第二终端设备103为例。
其中，网络设备101可以用于向网络请求获取第一终端设备102和第二终端设备103在同一时间的位置，并接收来自该网络的该第一终端设备102和第二终端设备103在同一时间的位置。在一种实现方式中，该网络中可以部署有可以用于获取终端设备(如第一终端设备 102和第二终端设备103)的位置的设备，且该设备可以按照指定时刻获取终端设备的位置。可以理解的是，网络设备101向网络请求获取第一终端设备102和第二终端设备103在同一时间的位置时，该网络可以通过前述部署的设备以获取第一终端设备102和第二终端设备103在同一时间的位置，并将所获取的位置反馈至前述网络设备101。需要说明的是，网络中可以部署有一个或多个设备。该网络可以通过其中部署的一个设备以获取第一终端设备102和第二终端设备103在同一时间的位置，或者，该网络可以通过其中部署的多个设备配合以获取第一终端设备102和第二终端设备103在同一时间的位置。本申请实施例对该网络中部署的用于获取第一终端设备102和第二终端设备103在同一时间的位置的网元的数量以及名称不做限定。在一种实现方式中，该网络中部署的设备可以包括测量设备，该测量设备可以用于测量第一终端设备102和/或第二终端设备103的位置。该测量设备可以为服务于第一终端设备102和/或第二终端设备103的接入网设备，或者该测量设备可以为第一终端设备102或第二终端设备103。
进一步的，网络设备101可以基于第一终端设备102和第二终端设备103在同一时间的位置，计算出该第一终端设备102与该第二终端设备103之间的距离。由于第一终端设备102的位置和第二终端设备103的位置是同一时间获取的，从而有利于提高第一终端设备102与第二终端设备103之间的距离计算的精度。
需要说明的是，本申请实施例除了可以应用于请求多个终端设备在同一时间的位置的场景，还可以应用于请求单个终端设备在特定时刻的位置的场景。还需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统。可选的，本申请实施例的方法还适用于未来的各种通信系统，例如6G系统或者其他通信网络等。
本申请实施例中的第一终端设备102和第二终端设备103是一种用于接收或发射信号的实体。第一终端设备102和第二终端设备103中的一方或者两方可发生移动，即第一终端设备102和第二终端设备103中的一方或者两方的位置可能发生变化。本申请实施例中的终端设备(即第一终端设备102或第二终端设备103)可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、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(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)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。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
在一种实现方式中，第一终端设备102和第二终端设备103可以为不同类型的设备。例如，第一终端设备102和第二终端设备103中的一方可以为控制设备，另一方可以为被该控制设备所控制的设备。如图1a所示，第一终端设备102为无人机，第二终端设备103为无人机控制器。在另一种实现方式中，第一终端设备102和第二终端设备103可以为同类型的设备。例如，第一终端设备102和第二终端设备103均为被控制设备(如无人机、遥控车等)。
本申请实施例中的网络设备101可以是网络侧的一种用于发射或接收信号的实体。该网络设备101可以为管理设备、网关移动位置中心(gateway mobile location centre，GMLC)、网络开放功能网元(network exposure function，NEF)、接入和移动管理功能网元(access and  mobility management function，AMF)、位置管理功能网元(location management function，LMF)或者其他可以用于获取第一终端设备102和第二终端设备103在同一时间的位置的设备。
其中，管理设备可以用于管理第一终端设备102的位置和第二终端设备103的位置，还可以用于第一终端设备102和第二终端设备103的授权和认证工作。例如，该管理设备可以对第一终端设备102的位置和/或第二终端设备103的位置进行分析，以确定第一终端设备102的位置或第二终端设备103的位置是否异常。或者，可以确定两者之间的距离是否异常。在第一终端设备102为无人机，第二终端设备103为无人机控制器的情况下，该管理设备可以是与无人机和无人机控制器追踪相关的网元。此时，该管理设备可以为无人机系统流量管理(UAV system traffic management，UTM)，UTM可以与无人机服务供应商(UAV system service provider，USS)部署在一起。需要说明的是，管理设备(如UTM)可以位于核心网内部，也可以位于核心网外部，本申请实施例对网元的名称以及所处的位置不做限定。
GMLC可以支持位置服务(location service，LCS)的功能。在一个公共陆地移动网络(public land mobile network，PLMN)中可以存在一个或多个GMLC。NEF可以用于提供从外部应用流程(如无人机系统)到3GPP网络的安全信息，还可以用于内部到外部信息的翻译。AMF可以用于管理终端设备的注册和连接等。LMF可以用于管理注册或接入5G核心网的终端设备的位置所需的资源的总体协调和调度。
在请求获取终端设备(如第一终端设备和/或第二终端设备)在指定时刻的位置的过程中所涉及的设备可以包括管理设备、一个或多个核心网设备以及测量设备，如图1b所示。以位置请求过程中所涉及的核心网设备包括GMLC、AMF和LMF为例，管理设备在需要获取终端设备在指定时刻的位置的情况下，可以向该终端设备对应的GMLC请求获取该终端设备在指定时刻的位置。该GMLC可以向终端设备对应的AMF请求获取该终端设备在指定时刻的位置。该AMF可以向该终端设备对应的LMF请求获取该终端设备在指定时刻的位置。该LMF可以向该终端设备对应的测量设备请求获取该终端设备在指定时刻的位置。该测量设备在获取到该终端设备在指定时刻的位置后，可以向该LMF反馈该位置。相应的，该LMF可以将该位置反馈给前述AMF。该AMF可以将该位置反馈给GMLC。然后，该GMLC将该位置反馈给前述管理设备。
需要说明的是，上述过程可以用于获取一个终端设备在指定时刻的位置，也可以用于获取多个终端设备在指定时刻的位置。还需要说明的是，上述管理设备通过该终端设备对应的GMLC以向该终端设备对应的AMF请求获取该终端设备在指定时刻的位置，仅用于举例。在其他可行的实现方式中，该管理设备还可以直接向该终端设备对应的AMF请求获取该终端设备在指定时刻的位置。或者，该管理设备可以通过该终端设备对应的NEF以向该终端设备对应的AMF请求获取该终端设备在指定时刻的位置，本申请实施例对在请求获取终端设备在指定时刻的位置的过程中所涉及的设备的数量和名称，以及设备之间的通信方式(如通过其他网元间接通信，或者直接通信)不做限定。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请提供的位置获取方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种位置获取方法的流程示意图。其中，步骤 S201～步骤S202的执行主体可以为管理设备、GMLC、NEF、AMF、LMF或者其他可以用于获取第一终端设备和第二终端设备在同一时间的位置的设备。或者，执行主体也可以为管理设备、GMLC、NEF、AMF或LMF中的芯片。如图2所示，该方法可以包括但不限于如下步骤：
步骤S201：向网络请求获取第一终端设备和第二终端设备在同一时间的位置。
第一终端设备和第二终端设备对应的网络可以相同，也可以不同。通过终端设备(如第一终端设备或第二终端设备)对应的网络可以获取该终端设备在指定时刻的位置。该终端设备对应的网络中可以部署有用于测量该终端设备在指定时刻的位置的测量设备。该网络在接收到关于获取该终端设备在指定时刻的位置的请求时，可以触发该测量设备对该终端设备进行定位，以获取该终端设备在指定时刻的位置。
在本申请实施例中，可以通过如下两种方式向网络请求获取第一终端设备和第二终端设备在同一时间的位置：
第一种，在第一终端设备和第二终端设备对应的网络设备相同的情况下，向该网络设备请求获取第一终端设备和第二终端设备在同一时间的位置。具体的，向该网络设备请求获取第一终端设备和第二终端设备在同一时间的位置的具体实施方式可以为：发送第一位置请求至第一网络设备，该第一位置请求用于请求获取第一终端设备和第二终端设备在同一时间的位置。其中，该第一网络设备服务于该第一终端设备和该第二终端设备。在本申请实施例中，该第一网络设备可以为GMLC、NEF、AMF或者LMF。相应的，第一网络设备获取到第一终端设备和第二终端设备在同一时间的位置后，可以向该第一位置请求的发送方反馈第一位置信息，该第一位置信息包括该第一终端设备和该第二终端设备在同一时间的位置。在第一终端设备和第二终端设备对应的网络设备相同的情况下，通过向该网络设备发送一个位置请求(第一位置请求)，可以获取第一终端设备和第二终端设备在同一时间的位置。在本申请实施例中，为了获取第一终端设备和该第二终端设备在同一时间的位置，该第一位置请求所包括的信息可以分为3种情况，具体可参见图3a-图5a实施例中的描述。
需要说明的是，在本申请实施例中，接收到位置请求(用于获取一个终端设备在指定时刻的位置，或者用于获取多个终端设备在同一时间的位置)的设备可以支持延时位置请求。支持延时位置请求表示：接收到位置请求后，该设备可以不用立即向该位置请求的发送方(即位置请求方)反馈所请求的位置信息，可以在获取到所需的位置信息后再反馈。可选的，该设备在接收到位置请求后，可以向该位置请求方发送位置响应，该位置响应可以用于指示该设备成功接收到该位置请求。该位置响应可以携带有位置请求方所需的位置信息，也可以未携带有位置请求方所需的位置信息。若该位置响应未携带有位置请求方所需的位置信息，该设备在发送位置响应之后，可以在获取到位置请求方所需的位置信息后，向该位置请求方反馈该位置信息。在本申请实施例中，位置信息可以携带于位置事件通知中发送给位置请求方。
还需要说明的是，在本申请实施例中，位置请求用于请求多个终端设备在同一时间的位置时，各个终端设备的位置可以携带于同一消息中反馈至位置请求方，也可以分别携带于不同的消息中反馈至位置请求方。例如，上述第一位置信息包括的第一终端设备的位置和第二终端设备的位置可以是分开发送的。
第二种，在第一终端设备和第二终端设备对应的网络设备不同的情况下，向第一终端设备对应的网络设备请求获取第一终端设备在第一时刻的位置，并向第二终端设备对应的网络设备请求获取第二终端设备在第一时刻的位置。
需要说明的是，在本申请实施例中，在向第一终端设备对应的网络设备和/或第二终端设 备对应的网络设备发送位置请求时，该位置请求表示期望在同一时刻(如第一时刻)下获取第一终端设备和第二终端设备的位置。但是在实际情况下，第一终端设备对应的测量设备可以是在该第一时刻左右对该第一终端设备的位置进行测量，即实际获取到的第一终端设备的位置可能不是在第一时刻下测量得到的，第二终端设备同理。但是由于实际测量终端设备(第一终端设备、第二终端设备)的位置时是按照该第一时刻测量的，所以按照该方式获取第一终端设备和第二终端设备的位置，有利于提高第一终端设备与第二终端设备之间的距离计算的精度。
在一种实现方式中，当期望获取第一终端设备在第一时刻的位置时，第一终端设备对应的测量设备可以在该第一时刻到来之前开始进行测量。由于测量设备测量第一终端设备的位置需要花费一定时间，因此在第一时刻之前开始测量，可以使得测量得到的第一终端设备的位置对应的实际时刻与该第一时刻(期望时刻)之间的误差较小，甚至使得实际时刻与期望时刻相同。
步骤S202：接收来自该网络的该第一终端设备和该第二终端设备在同一时间的位置。
若采用上述第一种方式请求获取第一终端设备和第二终端设备在同一时间的位置，相应的，可以接收该第一终端设备和第二终端设备对应的网络所反馈的该第一终端设备和第二终端设备在同一时间的位置。
若采用上述第二种方式请求获取第一终端设备和第二终端设备在同一时间的位置，相应的，可以接收该第一终端设备对应的网络所反馈的该第一终端设备在第一时刻的位置，并接收该第二终端设备对应的网络所反馈的该第二终端设备在第一时刻的位置。
在本申请实施例中，由于第一终端设备的位置和第二终端设备的位置是同一时间获取的，从而有利于提高第一终端设备与第二终端设备之间的距离计算的精度。
请参见图3a，图3a是本申请实施例提供的另一种位置获取方法的流程示意图，该方法详细描述了该第一位置请求包括第一时间信息时，如何获取第一终端设备和第二终端设备在同一时间的位置。其中，步骤S301～步骤S302的执行主体为管理设备、GMLC、NEF、AMF、LMF或者其他可以用于获取第一终端设备和第二终端设备在同一时间的位置的设备。或者，执行主体也可以为管理设备、GMLC、NEF、AMF或LMF中的芯片。该方法可以包括但不限于如下步骤：
步骤S301：发送第一位置请求至第一网络设备，该第一位置请求包括第一时间信息，该第一时间信息用于指示第一时刻；该第一位置请求用于请求获取第一终端设备和第二终端设备在该第一时刻的位置。
第一位置请求包括第一时间信息时，第一网络设备在接收到该第一位置请求后，按照该第一位置请求中携带的第一时间信息所指示的第一时刻获取第一终端设备和第二终端设备的位置即可。
在本申请实施例中，第一网络设备可以为服务于该第一终端设备和第二终端设备的网络设备，如GMLC、NEF、AMF或者LMF。以第一网络设备为AMF为例，该第一网络设备可以通过如下方式获取第一终端设备和第二终端设备在第一时刻的位置，其场景示意图如图3b所示：在第一终端设备对应的LMF和第二终端设备对应的LMF相同的情况下，该第一网络设备向该LMF发送位置请求1，该位置请求1用于请求获取第一终端设备和第二终端设备在第一时刻的位置。相应的，该LMF在接收到该位置请求1之后，可以向第一终端设备对应的测量设备发送位置请求2，并向第二终端设备对应的测量设备发送位置请求3。其中，该位置 请求2用于请求获取第一终端设备在第一时刻的位置，该位置请求3用于请求获取第二终端设备在第一时刻的位置。
相应的，第一终端设备对应的测量设备在接收到该位置请求2之后，可以测量得到第一终端设备在第一时刻的位置，并将测量得到的位置反馈至该LMF。同理，第二终端设备对应的测量设备在接收到该位置请求3之后，可以测量得到第二终端设备在第一时刻的位置，并将测量得到的位置反馈至该LMF。该LMF在接收到第一终端设备和第二终端设备在第一时刻的位置之后，可以将接收到的位置反馈至该AMF。相应的，该AMF可以将接收到的位置携带于第一位置信息中反馈至管理设备。其中，位置请求1、位置请求2和位置请求3可以包括前述第一时间信息，或者可以包括第一时刻。本申请实施例对此不做限定。
在另一种实现方式中，以第一网络设备为AMF为例，该第一网络设备可以通过如下方式获取第一终端设备和第二终端设备在第一时刻的位置，其场景示意图如图3c所示：在第一终端设备对应的LMF和第二终端设备对应的LMF不同的情况下，该第一网络设备可以向该第一终端设备对应的LMF发送位置请求4，并向第二终端设备对应的LMF发送位置请求5。其中，该位置请求4用于请求获取第一终端设备在第一时刻的位置，该位置请求5用于请求获取第二终端设备在第一时刻的位置。相应的，该第一终端设备对应的LMF在接收到该位置请求4之后，可以向第一终端设备对应的测量设备发送位置请求6，以请求获取第一终端设备在第一时刻的位置。同理，该第二终端设备对应的LMF在接收到该位置请求5之后，可以向第二终端设备对应的测量设备发送位置请求7，以请求获取第二终端设备在第一时刻的位置。可以理解的是，各个设备(测量设备、LMF、AMF)在获取到所需的位置后，可以向上一个设备反馈所获取的位置。具体过程可参照图3b，此处不再赘述。
需要说明的是，图3b和图3c以管理设备为第一位置请求的发送方为例，并不构成对本申请实施例的限定。在其他实施例中，第一位置请求的发送方还可以为GMLC、NEF或者其他设备。还需要说明的是，图3b中第一终端设备对应的测量设备和第二终端设备对应的测量设备不同仅用于举例，在其他实施例中，第一终端设备对应的测量设备和第二终端设备对应的测量设备可以相同。在此情况下，LMF可以向一个测量设备请求获取第一终端设备和第二终端设备在第一时刻的位置。
可以理解的是，若第一网络设备为LMF，该第一网络设备在接收到第一位置请求后，可以向测量设备请求获取第一终端设备和第二终端设备在第一时刻的位置。参见上述，当第一终端设备对应的测量设备和第二终端设备对应的测量设备相同时，LMF可以仅向该测量设备请求获取第一终端设备和第二终端设备在第一时刻的位置。当第一终端设备对应的测量设备和第二终端设备对应的测量设备不同时，LMF可以向第一终端设备对应的测量设备请求获取第一终端设备在第一时刻的位置，并向第二终端设备对应的测量设备请求获取该第二终端设备在第一时刻的位置。
在一种实现方式中，第一网络设备可以为定位该第一终端设备和第二终端设备的测量设备。定位该第一终端设备和第二终端设备的测量设备可以为服务于该第一终端设备和第二终端设备的接入网设备。
在本申请实施例中，第一位置请求包括第一时间信息的情况下，该第一时间信息可以是由在位置请求过程中处于该第一网络设备之前的某个设备确定的。以在位置请求过程中所涉及的核心网设备包括GMLC、AMF和LMF，且第一网络设备为AMF为例，该第一时间信息可以是由GMLC或者管理设备确定的。
在一种实现方式中，该第一时间信息可以包括该第一时刻或者第一时长，该第一时长用 于指示该第一时刻。该第一时刻可以是协调统一时间(coordinated universal time，UTC)。该第一时长可以是距离时刻1的时长，该时刻1加上第一时长即为该第一时刻。其中，该时刻1可以是预设的某个时刻。或者，该时刻1也可以是发起位置请求之后的某个准点时刻。需要说明的是，该时刻1可以由网络配置(例如，在系统消息或专有信令中下发)，或协议约定，或者可以由用户设置以及更改，本申请实施例对此不做限定。
在一种实现方式中，第一位置请求还可以包括以下至少一项：时间精度要求，第二时间信息。其中，该时间精度要求可以用于指示定位该第一终端设备的位置的时间与定位该第二终端设备的位置的时间需要满足的时间精度。定位该第一终端设备的位置的时间为定位第一终端设备的位置的实际时间，第一时刻为定位该第一终端设备的位置的期望时间。
在一种实现方式中，该时间精度要求可以包括一精度时间段或者精度时长。该时间精度要求包括精度时长时，定位第一终端设备的位置的时间满足时间精度可以指：定位第一终端设备的位置的时间(即实际时间)与第一时刻(即期望时间)之间的差值的绝对值小于该精度时长。该时间精度要求包括精度时间段时，定位第一终端设备的位置的时间满足时间精度可以指：定位第一终端设备的位置的时间位于该精度时间段内。该精度时间段的开始时刻和结束时刻与该第一时刻之间相距的时长均较小。
该第二时间信息可以用于指示定位该第一终端设备的位置的时间和定位该第二终端设备的位置的时间需要早于第二时刻。该第二时刻为可接受的最迟位置时间，即定位终端设备(第一终端设备、第二终端设备)的位置的时间(即实际时间)最迟为该第二时刻，若定位终端设备的位置的时间早于或等于该第二时刻，那么发起位置请求的设备(如管理设备)可以接受定位得到的该终端设备的位置。若定位终端设备的位置的时间晚于该第二时刻，那么发起位置请求的设备不能接受定位得到的该终端设备的位置。此时，可以不向发起位置请求的设备反馈定位得到的该终端设备的位置，这样有利于避免不必要的资源消耗。
在一种实现方式中，该第二时间信息可以包括该第二时刻或者包括用于指示该第二时刻的第二时长。该时长可以是距离时刻2的时长，该时刻2加上第二时长即为该第二时刻。其中，该时刻2可以是预设的某个时刻。或者，该时刻2也可以是发起位置请求之后的某个准点时刻。需要说明的是，该时刻2可以由网络配置(例如，在系统消息或专有信令中下发)，或协议约定，或者可以由用户设置以及更改，本申请实施例对此不做限定。
在一种实现方式中，第一位置请求还可以包括周期时间信息，该周期时间信息用于指示周期时长。此时，该第一位置请求具体可以用于请求以该第一时刻作为起始时刻，且以该周期时长作为时间间隔周期性获取第一终端设备和第二终端设备的位置。
在一种实现方式中，当第一位置请求包括周期时间信息时，前述第二时刻可以是第一时刻(即起始时刻)后经过一个或多个时间间隔的时刻。例如，当第一时刻为2:00:00，时间间隔为5分钟时，若前述第二时间信息指示第3个时间间隔，那么第二时刻可以为2:15:00。
在一种实现方式中，当第一位置请求包括周期时间信息，且时间精度要求包括精度时长时，在某个周期定位第一终端设备的位置的时间满足时间精度可以指：在该周期定位第一终端设备的位置的时间(即实际时间)与该周期对应的期望时间之间的差值的绝对值小于该精度时长。每个周期均对应一个期望时间，例如，当周期的起始时间(即第一时刻)为2:00:00，时间间隔为5分钟时，第一个周期对应的期望时间即为该第一时刻，第二周期对应的期望时间为2:05:00，第三周期对应的期望时间为2:10:00。同理，在一种实现方式中，当第一位置请求包括周期时间信息时，每个周期可以对应一个精度时间段。在某个周期定位第一终端设备的位置的时间满足时间精度可以指：在该周期定位第一终端设备的位置的时间(即实际时间) 位于该周期对应的精度时间段内。
请参见图3d，为周期位置请求流程的示意图。图3d以第一终端设备和第二终端设备对应的AMF、LMF均相同为例，但并不构成本申请实施例的限定。图3d在图3b所示的场景下，第一位置请求还包括周期时间信息。相应的，位置请求1、位置请求2和位置请求3也包括周期时间信息。其中，第一位置请求和位置请求1用于请求以第一时刻作为起始时刻，且以周期时间信息所指示的周期时长作为时间间隔周期性获取第一终端设备和第二终端设备的位置。位置请求2用于请求以第一时刻作为起始时刻，且以周期时间信息所指示的周期时长作为时间间隔周期性获取第一终端设备的位置，同理，位置请求3用于请求以第一时刻作为起始时刻，且以周期时间信息所指示的周期时长作为时间间隔周期性获取第二终端设备的位置。
需要说明的是，图3d中位置请求2和位置请求3同时包括第一时间信息和周期时间信息仅用于举例，在其他实施例中，可以将第一时间信息和周期时间信息分开发送至测量设备(第一终端设备对应的测量设备、第二终端设备对应的测量设备)。例如，位置请求2包括第一时间信息，周期时间信息包括于周期调用请求1中由LMF发送给第一终端设备对应的测量设备。其中，位置请求2用于请求获取第一终端设备在第一时刻的位置，周期调用请求1用于请求以第一时刻作为起始时刻，且以该周期时长作为时间间隔周期性获取第一终端设备的位置。该周期调用请求1可以包括第一时间信息，也可以不包括第一时间信息。例如，由于位置请求2包括第一时间信息，第一终端设备对应的测量设备在接收到该位置请求2之后，可以存储该第一时间信息。当接收到周期调用请求1时，隐式地确定是基于第一时间信息所指示的第一时刻周期性上报第一终端设备的位置。
第一终端设备对应的测量设备在接收到图3d中的位置请求2(包括周期时间信息)或者周期调用请求1后，可以反馈周期调用结果1。该周期调用结果1可以用于指示该测量设备是否支持基于第一时刻周期性上报第一终端设备的位置。LMF在接收到周期调用结果1之后，可以将该周期调用结果1所指示的信息反馈至管理设备(图3d未示出)。若第一终端设备对应的测量设备支持基于第一时刻周期性上报第一终端设备的位置，则该测量设备可以每隔前述周期时长测量一次第一终端设备的位置，并反馈测量得到的位置。需要说明的是，周期性测量得到的第一终端设备的位置可以携带于事件通知中反馈至管理设备。
同理，周期时间信息可以包括于周期调用请求2中由LMF发送给第二终端设备对应的测量设备，此时，图3d中的位置请求3不包括周期时间信息。该位置请求3用于请求获取第二终端设备在第一时刻的位置，周期调用请求2用于请求以第一时刻作为起始时刻，且以该周期时长作为时间间隔周期性获取第二终端设备的位置。第二终端设备对应的测量设备在接收到图3d中的位置请求3(包括周期时间信息)或者周期调用请求2后，可以反馈周期调用结果2。该周期调用结果2可以用于指示该测量设备是否支持基于第一时刻周期性上报第二终端设备的位置。需要说明的是，第二终端设备对应的测量设备周期性测量该第二终端设备的位置，与第一终端设备对应的测量设备周期性测量该第一终端设备的位置类似。反馈周期性测量得到的该第二终端设备的位置的流程，与反馈周期性测量得到的该第二终端设备的位置的流程类似，此处不再赘述。还需要说明的是，在周期位置请求过程中，第一终端设备对应的测量设备可以将周期性测量得到的多个位置一起反馈至位置请求方，也可以每测量得到一个位置就反馈至位置请求方，本申请实施例对周期性测量得到的位置信息的反馈方式不做限定。
需要说明的是，在本申请实施例中，在发送第一位置请求至第一网络设备之前，可以查 询第一终端设备和第二终端设备的隐私设置，若第一终端设备和第二终端设备中的至少一个不允许被定位，后续步骤不再执行。本申请实施例是在假设第一终端设备和第二终端设备均允许被定位的前提下进行描述的。还需要说明的是，查询第一终端设备和第二终端设备的隐私设置的执行主体可以是GMLC或者其他设备，本申请实施例对此不作限定。
步骤S302：接收来自该第一网络设备的第一位置信息，该第一位置信息包括该第一终端设备和该第二终端设备在第一时刻的位置。
当第一位置请求不包括周期时间信息时，该第一位置信息可以仅包括该第一终端设备和该第二终端设备在第一时刻的位置。在一种实现方式中，当第一位置请求包括时间精度要求时，该第一位置信息还可以包括时间精度结果，该时间精度结果可以用于指示第一终端设备和第二终端设备的位置是否满足时间精度要求。即用于指示定位该第一终端设备的位置的时间与定位该第二终端设备的位置的时间是否满足时间精度。需要说明的是，时间精度结果可以与终端设备的位置一同反馈。若该终端设备包括第一终端设备，则该时间精度结果可以用于指示第一终端设备的位置是否满足时间精度要求。还需要说明的是，本申请实施例对位置请求过程和位置反馈过程中涉及的信息或者消息的名称不做限定。例如，时间精度结果也可以称为精度满足指示。
当第一位置请求包括周期时间信息时，第一位置信息可以包括以该第一时刻作为起始时刻，周期性获取的第一终端设备和第二终端设备的位置。当第一位置请求包括时间精度要求时，该第一位置信息还可以包括对于每个周期的时间精度结果。对于某周期的时间精度结果可以用于指示在该周期定位该第一终端设备的位置的时间与定位该第二终端设备的位置的时间是否满足时间精度。
在一种实现方式中，若实际获取到的第一终端设备的位置和第二终端设备的位置不是在第一时刻下测量得到的，此时，第一位置信息还可以包括定位第一终端设备的位置的实际时间和定位第二终端设备的位置的实际时间。这样接收到第一位置信息的设备可以根据前述时间精度要求和定位第一终端设备的位置的实际时间，判断定位第一终端设备的位置的实际时间是否满足时间精度。以及根据前述时间精度要求和定位第二终端设备的位置的实际时间，判断定位第二终端设备的位置的实际时间是否满足时间精度。
需要说明的是，上述第一位置信息包括定位第一终端设备的位置的实际时间和定位第二终端设备的位置的实际时间仅用于举例，定位第一终端设备的位置的实际时间和定位第二终端设备的位置的实际时间可以包括于其他位置信息中。具体的，定位第一终端设备的位置的实际时间可以与第一终端设备的位置一同反馈，同理，定位第二终端设备的位置的实际时间可以与第二终端设备的位置一同反馈。
在本申请实施例中，由于第一终端设备的位置和第二终端设备的位置是同一时间获取的，从而有利于提高第一终端设备与第二终端设备之间的距离计算的精度。
请参见图4a，图4a是本申请实施例提供的又一种位置获取方法的流程示意图，该方法详细描述了第一位置请求包括第一指示信息时，如何获取第一终端设备和第二终端设备在同一时间的位置。其中，步骤S401～步骤S402的执行主体为管理设备、GMLC、NEF、AMF、LMF或者其他可以用于获取第一终端设备和第二终端设备在同一时间的位置的设备。或者，执行主体也可以为管理设备、GMLC、NEF、AMF或LMF中的芯片。该方法可以包括但不限于如下步骤：
步骤S401：发送第一位置请求至第一网络设备，该第一位置请求包括第一指示信息，该 第一指示信息用于指示获取第一终端设备和第二终端设备在同一时间的位置。
第一位置请求包括第一指示信息时，该第一位置请求可以未指示获取位置的时刻。第一网络设备在接收到该第一位置请求后，可以确定一个时刻(如第一时刻)，然后按照该第一时刻获取第一终端设备和第二终端设备的位置。需要说明的是，在第一网络设备确定第一时刻之后，按照该第一时刻获取第一终端设备和第二终端设备的位置的过程可以参见图3a中第一位置请求包括第一时间信息时，按照该第一时刻获取第一终端设备和第二终端设备的位置的过程，此处不再赘述。
在一种实现方式中，第一位置请求可以不包括该第一指示信息，该第一位置请求可以隐式指示期望获取第一终端设备和第二终端设备在同一时间的位置。在此情况下，第一网络设备在接收到该第一位置请求后，也需要确定第一时刻。
需要说明的是，在第一位置请求显式指示(即第一位置请求包括第一指示信息)或者隐式指示期望获取第一终端设备和第二终端设备在同一时间的位置的情况下，第一时刻由第一网络设备确定仅用于举例。该第一网络设备为服务于该第一终端设备和第二终端设备的网络设备。在一种实现方式中，在位置请求过程中该第一网络设备之后的第一个设备若同时服务于第一终端设备和第二终端设备，那么第一时刻可以由该第一个设备确定。可以理解的是，若该第一网络设备之后的第一个设备和第二个设备均能同时服务于第一终端设备和第二终端设备，那么第一时刻可以由该第二个设备或者第一个设备确定。以此类推，第一时刻可以由位置请求过程中能同时服务于第一终端设备和第二终端设备的最后一个设备确定，或者由该最后一个设备之前的设备确定。
以在位置请求过程中所涉及的核心网设备包括GMLC、AMF和LMF，且第一网络设备为AMF为例，LMF为AMF之后的第一个设备，测量设备为AMF之后的第二个设备。若第一终端设备对应的LMF与第二终端设备对应的LMF相同，且第一终端设备对应的测量设备与第二终端设备对应的测量设备不同，即LMF为位置请求过程中能同时服务于第一终端设备和第二终端设备的最后一个设备。此时，第一时刻可以由LMF或者AMF确定。第一时刻由AMF确定的场景示意图可以如图4b所示。图4b中，AMF确定第一时刻后，可以向第一终端设备和第二终端设备对应的AMF发送位置请求8，该位置请求8用于请求获取第一终端设备和第二终端设备在第一时刻的位置。相应的，该LMF接收到位置请求8后，可以向第一终端设备对应的测量设备发送位置请求9，以请求获取第二终端设备在第一时刻的位置，并向第二终端设备对应的测量设备发送位置请求10，以请求获取第二终端设备在第一时刻的位置。其中，位置请求8、位置请求9和位置请求10可以包括该第一时刻。
在一种实现方式中，在第一位置请求未指示获取位置的时刻的情况下，第一网络设备在接收到该第一位置请求后，可以确定第三时间信息，该第三时间信息可以用于指示一个时刻(如第一时刻)。该第三时间信息可以包括该第一时刻或者一个时长，该时长用于指示该第一时刻。此时，在图4b中，位置请求8、位置请求9和位置请求10可以包括该第三时间信息或者该第一时刻。
需要说明的是，第一位置请求还可以包括以下至少一项：时间精度要求，第二时间信息，周期时间信息。关于时间精度要求、第二时间信息和周期时间信息的具体描述可参见图3a所示实施例，此处不再赘述。
步骤S402：接收来自该第一网络设备的第一位置信息，该第一位置信息包括该第一终端设备和该第二终端设备在第一时刻的位置。
需要说明的是，步骤S402的执行过程可参见图3a中步骤S302的具体描述，此处不再赘 述。
在本申请实施例中，由于第一终端设备的位置和第二终端设备的位置是同一时间获取的，从而有利于提高第一终端设备与第二终端设备之间的距离计算的精度。
请参见图5a，图5a是本申请实施例提供的又一种位置获取方法的流程示意图，该方法详细描述了第一位置请求包括第一终端设备的偏差时间信息时，如何获取第一终端设备和第二终端设备在同一时间的位置。其中，步骤S501～步骤S503的执行主体为管理设备、GMLC、NEF、AMF、LMF或者其他可以用于获取第一终端设备和第二终端设备在同一时间的位置的设备。或者，执行主体也可以为管理设备、GMLC、NEF、AMF或LMF中的芯片。该方法可以包括但不限于如下步骤：
步骤S501：确定第一终端设备的偏差时间信息，该偏差时间信息是根据定位该第一终端设备的历史位置的时间和定位第二终端设备的历史位置的时间确定的；该偏差时间信息用于调整定位该第一终端设备的位置的时间，使能获取该第一终端设备和第二终端设备在同一时间的位置。
在本申请实施例中，若定位第一终端设备的位置的时间与定位第二终端设备的位置的时间不同，可以确定第一终端设备或第二终端设备的偏差时间信息，并通过该偏差时间信息调整定位该第一终端设备或者第二终端设备的位置的时间，使能获取该第一终端设备和第二终端设备在同一时间的位置。可以理解的是，第二终端设备的偏差时间信息用于调整定位该第二终端设备的位置的时间。本申请实施例以确定第一终端设备的偏差时间信息为例进行介绍。通过调整定位第一终端设备和第二终端设备中的一方的时间，即可达到获取该第一终端设备和第二终端设备在同一时间的位置的目的，而无需调整定位两者的位置的时间，有利于减小开销。
其中，该偏差时间信息可以是在位置请求过程中处于第一网络设备之前的某个设备确定的。该第一网络设备服务于第一终端设备和第二终端设备。以在位置请求过程中所涉及的核心网设备包括GMLC、AMF和LMF，且第一网络设备为AMF为例，该偏差时间信息可以是由GMLC或者管理设备确定的。具体的，该设备可以通过以下方式确定该偏差时间信息：根据定位第一终端设备的历史位置的时间和定位该第二终端设备的历史位置的时间确定该偏差时间信息。
具体的，可以将定位第二终端设备的历史位置的时间，与定位该第一终端设备的历史位置的时间之间的差值，确定为该第一终端设备的偏差时间信息。例如，当定位第一终端设备的历史位置的时间为12:00:00，定位该第二终端设备的历史位置的时间为12:02:00时，第一终端设备的偏差时间信息可以为2分钟。
在本申请实施例中，可以在不同时间下对第一终端设备(或第二终端设备)进行定位，即定位第一终端设备(或第二终端设备)的历史位置的时间可以有多个。在一种实现方式中，前述定位第一终端设备(或第二终端设备)的历史位置的时间可以是指上一次定位该第一终端设备(或第二终端设备)的位置的时间。
在本申请实施例中，该偏差时间信息用于调整定位该第一终端设备的位置的时间，调整后的定位该第一终端设备的位置的时间与(未经调整的)定位第二终端设备的位置的时间相同。即通过调整定位该第一终端设备的位置的时间，可以获取该第一终端设备和第二终端设备在同一时间的位置。测量设备在获取该第一终端设备的偏差时间信息之后，可以根据该偏差时间信息以及上一次定位该第一终端设备的位置的时间，确定本次定位该第一终端设备的 位置的时间。例如，若上一次定位该第一终端设备的位置的时间为12:00:00，上一次定位第二终端设备的位置的时间为12:02:00，且该第一终端设备的偏差时间信息为2分钟，则本次定位该第一终端设备的位置的时间可以为12:02:00。若本次定位第二终端设备的位置的时间与上一次定位该第二终端设备的位置的时间不变，可以使得本次定位第一终端设备和第二终端设备的位置的时间相同，即可以获取该第一终端设备和第二终端设备在同一时间的位置。
步骤S502：发送第一位置请求至第一网络设备，该第一位置请求包括该偏差时间信息；该第一位置请求用于请求获取第一终端设备和第二终端设备在同一时间的位置。
确定第一终端设备的偏差时间信息之后，可以发送携带有该偏差时间信息的第一位置请求至第一网络设备。需要说明的是，当该第一位置请求包括的是第一终端设备的偏差时间信息时，可以表示：需要根据该偏差时间信息调整定位该第一终端设备的位置的时间，但是保持定位第二终端设备的位置的时间不变。这样可以获取该第一终端设备和第二终端设备在同一时间的位置。在一种实现方式中，若该偏差时间信息是根据上一次定位第一终端设备的位置的时间和上一次定位第二终端设备的位置的时间确定的，那么，保持定位第二终端设备的位置的时间不变是指：保持定位第二终端设备的位置的时间与上一次定位第二终端设备的位置的时间相同。
在一种实现方式中，该第一位置请求除了包括偏差时间信息以外，还可以包括周期时间信息(参见图3a实施例中的具体描述)，此时，该第一位置请求用于请求周期性获取第一终端设备和第二终端设备在同一时间的位置。在此情况下，该偏差时间信息可以用于调整定位该第一终端设备的位置的周期起始时间。保持定位第二终端设备的位置的时间不变是指：保持定位第二终端设备的位置的周期起始时间不变。需要说明的是，在本申请实施例中，定位第一终端设备的周期与定位第二终端设备的周期相同，即第一终端设备和第二终端设备每隔相同时长进行一次定位。
步骤S503：接收来自该第一网络设备的第一位置信息，该第一位置信息包括该第一终端设备和该第二终端设备在同一时间的位置。
在本申请实施例中，第一网络设备接收到第一位置请求后，可以请求第一终端设备对应的测量设备请求按照偏差时间信息调整定位该第一终端设备的位置的时间，并反馈该第一终端设备的位置。需要说明的是，第一终端设备对应的测量设备反馈的该第一终端设备的位置，与第二终端设备对应的测量设备反馈的该第二终端设备的位置，是同一时间(接下来以该时间为第一时刻为例进行说明)测量得到的。
其中，第一网络设备接收到第一位置请求之前，可以请求第二终端设备对应的测量设备定位该第二终端设备在第一时刻的位置。换言之，请求获取第一终端设备在第一时刻的位置的流程，与请求获取第二终端设备在第一时刻的位置的流程可以是独立的。例如，第一网络设备接收到第一位置请求之前，请求第二终端设备对应的测量设备以第一时刻为起始时刻，周期性反馈该第二终端设备的位置。请求获取第二终端设备在第一时刻的位置的流程可以参见图2～图4a实施例中的具体描述。需要说明的是，请求获取第二终端设备在第一时刻的位置的流程中，所发送的位置请求可以不携带前述第一时间信息或者第一时刻。该位置请求可以隐式指示第二终端设备对应的测量设备按照上一次定位第二终端设备的位置的时间(即第一时刻)，获取该第二终端设备的位置。通过这种方式，可以获取第二终端设备在第一时刻的位置。还需要说明的是，第一网络设备可以直接向测量设备(第一终端设备对应的测量设备、第二终端设备对应的测量设备)发起上述请求，也可以通过其他中间设备向该测量设备发起上述请求。
以第一网络设备为AMF为例，请求获取第一终端设备在第一时刻的位置的流程示意图可以如图5b所示：第一网络设备接收到携带有第一终端设备的偏差时间信息的第一位置请求后，可以向LMF发送位置请求11，该位置请求11用于请求获取第一终端设备在第一时刻的位置。相应的，该LMF在接收到该位置请求11之后，可以向第一终端设备对应的测量设备发送位置请求12。其中，位置请求11和位置请求12携带有该偏差时间信息。该位置请求12用于请求根据偏差时间信息调整定位该第一终端设备的位置的时间，并按照调整后的时间获取第一终端设备的位置。调整后的时间为第一时刻。可以理解的是，各个设备(测量设备、LMF、AMF)在获取到所需的位置后，可以向上一个设备反馈所获取的位置。具体过程可参照图3b，此处不再赘述。
需要说明的是，图5b中位置请求12携带偏差时间信息仅用于举例。在一种实现方式中，若LMF已知上一次定位第一终端设备的位置的时间，则该LMF可以根据上一次定位第一终端设备的位置的时间以及偏差时间信息，调整定位该第一终端设备的位置的时间。调整后的时间为第一时刻。此时，该位置请求12可以携带该第一时刻。
需要说明的是，步骤S503的其余执行过程可参见图2中步骤S202的具体描述，此处不再赘述。
在本申请实施例中，通过在第一位置请求中携带第一终端设备的偏差时间信息，可以调整定位该第一终端设备的位置的时间，使能获取该第一终端设备和第二终端设备在同一时间的位置，从而有利于提高第一终端设备与第二终端设备之间的距离计算的精度。
请参见图6，图6是本申请实施例提供的又一种位置获取方法的流程示意图，该方法详细描述了如何分别向第一终端设备和第二终端设备对应的网络设备发送请求，以请求获取第一终端设备和第二终端设备在同一时间的位置。其中，步骤S601～步骤S602的执行主体为管理设备、GMLC、NEF、AMF、LMF或者其他可以用于获取第一终端设备和第二终端设备在同一时间的位置的设备。或者，执行主体也可以为管理设备、GMLC、NEF、AMF或LMF中的芯片。该方法可以包括但不限于如下步骤：
步骤S601：发送第二位置请求至第二网络设备，并发送第三位置请求至第三网络设备；该第二位置请求用于请求获取第一终端设备在第一时刻的位置，该第三位置请求用于请求获取第二终端设备在该第一时刻的位置。
在第一终端设备和第二终端设备对应的网络设备不同的情况下，可以向第一终端设备对应的网络请求获取第一终端设备在第一时刻的位置，并向第二终端设备对应的网络设备请求获取第二终端设备在第一时刻的位置。其中，向第一终端设备对应的网络设备请求获取第一终端设备在第一时刻的位置具体可以指：向第一终端设备对应的第二网络设备请求获取第一终端设备在第一时刻的位置。第二网络设备可以用于获取第一终端设备在指定时刻(如第一时刻)的位置。
在一种实现方式中，该第二网络设备可以为服务于该第一终端设备的网络设备；或者，该第二网络设备可以为定位该第一终端设备的第一测量设备；或者，该第二网络设备可以为该第一终端设备；或者，该第二网络设备可以为服务于该第一终端设备的接入网设备。同理，该第三网络设备可以为服务于该第二终端设备的网络设备；或者，该第三网络设备可以为定位该第二终端设备的第二测量设备；或者，该第三网络设备可以为该第二终端设备；或者，该第三网络设备可以为服务于该第二终端设备的接入网设备。在本申请实施例中，接入网设备可以为演进型基站(evolved NodeB，eNB)、NR系统中的下一代基站(next generation NodeB， gNB)或其他未来移动通信系统中的基站等。本申请的实施例对接入网设备所采用的具体技术和具体设备形态不做限定。
在一种实现方式中，在发送第二位置请求之前，还可以从多个网络设备中确定支持获取第一终端设备在第一时刻的位置的第二网络设备，并从多个网络设备中确定支持获取第二终端设备在第一时刻的位置的第三网络设备。例如，以发送第二位置请求的执行主体为AMF，第二网络设备为LMF为例，在第一终端设备对应的网络中可以存在多个LMF，其中，部分LMF支持获取第一终端设备在指定时刻(如第一时刻)的位置，另一部门LMF不支持获取第一终端设备在指定时刻(如第一时刻)的位置。此时，AMF可以从该多个LMF中确定支持获取第一终端设备在第一时刻的位置的LMF，并向该LMF发送第二位置请求。
在分别向第一终端设备对应的网络和第二终端设备对应的网络发送位置请求的情况下，为了获取第一终端设备和第二终端设备在同一时间的位置，第一测量设备在接收到第二位置请求后所确定的定位第一终端设备的时间，与第二测量设备在接收到第三位置请求后所确定的定位第二终端设备的时间需要相同。换言之，通过第二位置请求和第三位置请求可以使得第一测量设备和第二测量设备确定同一时刻(如第一时刻)。
通过第二位置请求和第三位置请求，使得第一测量设备和第二测量设备确定第一时刻的方式可以包括但不限于如下两种：
第一种：第二位置请求和第三位置请求均包括第一时间信息，该第一时间信息用于指示该第一时刻。该第一时间信息可以包括该第一时刻或者第一时长，该第一时长用于指示该第一时刻。关于第一指示信息的相关内容可参见图3a实施例中的具体描述，此处不再赘述。
第二种：第二位置请求包括第一终端设备的偏差时间信息，该偏差时间信息使能调整定位第一终端设备的位置的时间至该第一时刻；偏差时间信息是根据定位第一终端设备的历史位置的时间和定位第二终端设备的历史位置的时间确定的。该第三位置请求用于请求获取第二终端设备在该第一时刻的位置。通过调整定位第一终端设备和第二终端设备中的一方(以第一终端设备为例)的时间，即可达到获取该第一终端设备和第二终端设备在同一时间(第一时刻)的位置的目的，而无需调整定位两者的位置的时间，有利于减小开销。
关于第一终端设备的偏差时间信息的相关内容可参见图5a实施例中的具体描述，此处不再赘述。需要说明的是，第二位置请求包括第一终端设备的偏差时间信息时，该第三位置请求可以隐式指示请求获取第二终端设备在第一时刻的位置。例如，当定位第二终端设备的历史位置的时间为第一时刻时，第三位置请求具体可以用于指示按照定位第二终端设备的历史位置的时间(即第一时刻)，获取第二终端设备的位置。还需要说明的是，上述第二位置请求包括第一终端设备的偏差时间信息仅用于举例，在其他实施例中，也可以是第三位置请求包括第二终端设备的偏差时间信息。还需要说明的是，确定该第一终端设备的偏差时间信息的设备的相关内容可参见图5a实施例中的具体描述，此处不再赘述。
在一种实现方式中，第二位置请求和第三位置请求可以包括以下至少一项：时间精度要求、第二时间信息、周期时间信息。需要说明的是，若第二位置请求包括时间精度要求，那么第三位置请求也包括精度要求。若第二位置请求包括第二时间信息，那么第三位置请求也包括第二时间信息。若第二位置请求包括周期时间信息，那么第三位置请求也包括周期时间信息。关于时间精度要求、第二时间信息和周期时间信息的具体描述可参见图3a所示实施例，此处不再赘述。
步骤S602：接收来自第二网络设备的第二位置信息，并接收来自第三网络设备的第三位置信息；该第二位置信息包括该第一终端设备在第一时刻的位置，第三位置信息包括该第二 终端设备在第一时刻的位置。
第二网络设备接收到第二位置请求后，可以向第一测量设备请求获取第一终端设备在第一时刻的位置。同理，第三网络设备接收到第三位置请求后，可以向第二测量设备请求获取第二终端设备在第一时刻的位置。关于测量设备如何获取终端设备在指定时刻(如第一时刻)的位置可参见图2～图5a实施例中的具体描述，此处不再赘述。
第二网络设备获取到第一终端设备在第一时刻的位置后，可以向该第二位置请求的发送方反馈第二位置信息。同理，第三网络设备获取到第二终端设备在第一时刻的位置后，可以向该第三位置请求的发送方反馈第三位置信息。
在一种实现方式中，当第二位置请求包括时间精度要求时，该第二位置信息还可以包括对于每个周期的时间精度结果。同理，当第三位置请求包括时间精度要求时，该第三位置信息还可以包括对于每个周期的时间精度结果。
需要说明的是，第二网络设备获取第一终端设备在第一时刻的位置的执行过程与图3a、图5a实施例中第一网络设备获取第一终端设备在第一时刻的位置的执行过程基本相同。
在本申请实施例中，由于第一终端设备的位置和第二终端设备的位置均是第一时刻获取的，从而有利于提高第一终端设备与第二终端设备之间的距离计算的精度。
在一种实现方式中，管理设备(或者GMLC、NEF)在向网络请求获取第一终端设备在第一时刻的位置后，可以接收来自该网络的第二指示信息，该第二指示信息可以用于指示无法获取第一终端设备在第一时刻的位置。在一种实现方式中，该第二指示信息用于指示无法获取第一终端设备在第一时刻的位置时，还可以用于指示无法获取第一终端设备在第一时刻的位置的原因，具体可以通过原因值指示。无法获取第一终端设备在第一时刻的位置的原因可以为：第一终端设备在该第一时刻下不可达。
在另一种实现方式中，该第二指示信息可以用于指示无法获取第一终端设备在第一时刻的位置，且可以获取第一终端设备在第三时刻的位置。其中，该第三时刻晚于第一时刻。若管理设备(或者GMLC、NEF)可以接受第一终端设备在第三时刻的位置，则该管理设备可以等待网络反馈第一终端设备在第三时刻的位置。此时，该第三时刻早于前述第二时刻。
在一种实现方式中，第三时刻可以为第一时刻加N个时间间隔的时刻，其中，时间间隔为：周期性获取第一终端设备的位置的情况下，相邻两次获取第一终端设备的位置的时间之间间隔的时长。N可以为大于或等于1的整数。
在又一种实现方式中，该第二指示信息可以用于指示在第二时刻之前无法获取第一终端设备的位置。即在可接收的时间下无法获取第一终端设备的位置。
需要说明的是，上述第二指示信息用于指示是否能获取第一终端设备在某时刻(如第一时刻、第二时刻、第三时刻)的位置仅用于举例。第二指示信息也可以用于指示是否能获取第二终端设备在某时刻(如第一时刻、第二时刻、第三时刻)的位置。
