具体实施方式
为了便于理解，首先介绍本公开涉及的术语。
1、LTE定位协议(LTEPositioning Protocol,LPP)消息
LPP作为通用定位通信协议，主要功能在于在网络与终端之间交互定位辅助数据和定位信息。实际上它既可以在控制平面，也可以在数据平面使用。
其中，LPP消息可以用于核心网设备与终端设备之间的消息传输。
2、新空口定位协议A(new radio positioning protocol A，NRPPa)消息
NRPPa为用于规范基站和定位管理功能(Location Management Function，LMF)设备之间的控制平面无线网络层信令过程的协议。LMF与gNB之间的NRPPa消息可以分为：非终端设备相关(non UE associated)消息及终端设备相关(UE associated)消息。
其中，Non UE associated消息可以用来在基站和LMF之间传输TRP信息、测量信息及辅助信息等的传输。UE associated消息可以用来在基站和LMF之间传输指定的终端设备相关的信息，比如终端设备的TRP配置信息等。
为了更好的理解本公开实施例公开的一种定位方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开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核心网设备、一个接入网设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的 接入网设备，两个或两个以上的终端设备，两个或两个以上的核心网设备。图1所示的通信系统以包括一个核心网设备11、一个终端设备12和一个接入网设备10为例。

下面结合附图对本公开所提供的一种定位方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种定位方法的流程示意图。该方法被配置为由核心网设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤21，发送定位消息，其中，定位消息中包括用于指示返回应答信息的时间信息。
其中，该定位消息，可以为核心网设备发送给接入网设备的，或者也可以为核心网设备发送给终端设备的，本公开对此不做限定。
其中，核心网设备可以为LMF设备，本公开对此不做限定。
可选的，时间信息为以下任一项：时刻及时间长度。
即核心网设备可以指示接入网设备或者终端设备返回应答信息的时刻。比如，时间信息为时刻t 1，即指示接入网设备或者终端设备在t 1时刻之前返回应答信息。
或者，核心网设备还可以指示接入网设备或者终端设备，自接收到核心网设备发送定位消息的时刻开始计时，并在时间信息指示的时间长度内返回应答信息。比如，时间信息为时间长度t 2,接入网设备或终端设备接收定位消息的时刻为t 3，则接入网设备或者终端设备，需要在时刻t 3+t 2之前，返回应答信息。
可选的，定位消息为以下任一项消息：终端设备能力请求消息；定位测量结果请求消息；定位信息请求消息；以及，定位激活请求消息。
其中，终端设备能力请求消息为由核心网设备向终端设备发送的消息，用于获取终端设备的定位能力信息，例如LPP消息：LPP Request Capabilities。
其中，定位信息请求消息为由核心网设备向接入网设备发送的消息，用于获取指定的终端设备对应的上行定位参考信号配置信息，例如NRPPa消息：Positioning information request。
其中，定位激活请求消息为核心网设备获取的上行定位参考信号配置信息为非周期性或半持续性的情况下，核心网设备向接入网设备发送的消息，用于触发接入网设备向终端设备发送激活指示，以激活终端设备中指定的上行定位参考信号，或者指示接入网设备向终端设备发送去激活指示，以去激活终端设备中指定的上行定位参考信号，例如：NRPPa消息：Positioning Activation Request。
其中，定位测量结果请求消息由核心网设备向接入网设备发送的消息，用于获取上行定位参考信号测量结果，例如NRPPa消息：measurement request。
通过实施本公开实施例，核心网设备通过发送包含时间信息的定位消息，来指示接入网设备或终端设备在时间信息指示的时间内向核心网设备返回应答信息。因此，定位过程中的各个阶段的时间都受核心网设备控制，从而使得核心网设备可以在规定的时间范围内完成定位的准备工作，降低了定位时延。
请参见图3，图3是本公开实施例提供的另一种定位方法的流程示意图。该方法被配置为由核心网设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，接收定位请求消息，其中，定位请求消息中包括预定位置时间。
其中，该定位请求消息，可以为终端设备、定位服务代理或应用功能(Application functio，AF)发送给核心网设备的。预定位置时间为期望的目标终端设备的定位测量结果时间，即目标终端在该时间进行定位测量，和/或基站在该时间对目标终端进行定位测量。例如，预定位置时间为scheduled location time。其中，该预定位置时间，可以为时刻，也可以为时间长度。本公开对此不做限定。
步骤32，根据预定位置时间，确定时间信息。
其中，时间信息可以为时刻，也可以为时间长度，本公开对此不做限定。
具体的，核心网设备在收到包括预定位置时间的定位请求消息后，即可根据定位准备 工作需要的流程及该预定位置时间，确定各个定位准备流程对应的时间信息。
可选的，核心网设备可以根据预定位置时间及接收定位请求消息的时刻，确定时间信息。
比如，若接收定位请求消息的时刻为t m，预定位置时间为时间长度n，则核心网设备可以确定其需要在t m+n时刻之前，返回定位信息，从而即可确定各个定位准备流程对应的时间信息。
或者，若接收定位请求消息的时刻为t m，预定位置时间为时刻t n，则核心网设备可以确定其需要在t n时刻之前返回定位信息，即需要在t n-t m时间段内完成各个定位准备流程，从而即可确定各个定位准备流程对应的时间信息。
需要说明的是，上述示例只是举例说明，不能作为对本公开实施例中时间信息的限定。
可选的，核心网设备还可以根据预定位置时间及定位消息的类型，确定时间信息。
本公开中，由于定位消息可能是核心网设备发送给接入网设备的，或者也可能是发送给终端设备的。而不同类型的定位消息采用的协议可能不同，从而其对应的数据压缩方式可能不同，从而接入网设备或者终端设备处理该消息时所用的时间长度可能不同，因此，本公开中，核心网设备可以根据定位消息的类型及预定位置时间，确定时间信息。
比如，定位消息为终端设备能力请求消息时对应的时间信息，与定位消息为定位信息请求消息时对应的时间信息不同；或者，定位消息为终端设备能力请求消息时对应的时间信息与定位消息为定位激活请求消息时对应的时间信息不同。
需要说明的是，定位消息为终端设备能力请求消息、定位测量结果请求消息、定位信息请求消息及定位激活请求消息中的任一项时对应的时间信息可以相同也可以不同。
步骤33，发送定位消息，其中，定位消息中包括用于指示返回应答信息的时间信息。
其中，核心网设备发送定位消息的具体实现形式及定位消息的类型等，可参照本公开其他各实施例的详细描述，此处不再赘述。
