具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
为了便于理解，首先介绍本公开涉及的术语。
1、定位管理功能(location management function，LMF)
定位管理功能(location management function，LMF)管理注册到5G核心网(5G core network，5GCN)或访问5GCN的终端设备的位置所需的资源的总体协调和调度。它还可以计算或验证最终位置和任何速度估计值，并可以估计达到的精度。LMF使用基于定位管理功能业务(service-basedinterface exhibited by LMF，Nlmf)接口从接入及移动性管理功能(access and mobility management function，AMF)接收对目标终端设备的位置请求。LMF与终端设备交互以交换适用于终端设备辅助和基于终端设备的定位方法的位置信息，并与5G接入网络(NG Radio Access Network，NG-RAN)交互以获得位置信息。
2、定时提前量(timing advance，TA)
定时提前量TA用于上行同步，TA timer超时，意味着UE与gNB已经没有上行同步，只有UE与gNB保持上行同步时，UE发送的上行定位参考信号，gNB才能正确接收。
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接入网设备、一个核心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，两个以上的核心网设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备11、一个核心网设备13和一个终端设备12为例。
需要说明的是，本公开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，或者其他未来的新型移动通信系统等。
本公开实施例中的接入网设备11是网络侧的一种用于发射或接收信号的实体。例如，接入网设备11可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的接入网设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备12是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、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)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设 备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开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。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
通常，接入网设备为RRC非连接态(包括RRC非激活态和RRC空闲态)终端设备配置的上行定位参考信号是有时效性的，当LMF向基站请求定位参考信号的测量结果时，若上行定位参考信号已失效，则会导致获取定位信息失败。因此，接入网设备、LMF和终端设备之间，可以通过交互上行参考信号的有效性，来避免获取定位信息失败的现象。即LMF可以在确定上行参考信号的有效的情况下，再向接入网设备请求获取上行定位参考信号的测量结果，而上行定位参考信号的失效的情况下，则可以向接入网设备请求重新分配上行定位参考信号。
下面结合附图对本公开所提供的一种定位的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的方法的流程示意图，该方法由核心网设备执行。本公开中，核心网设备可以为LMF网元，以下实施例以LMF网元为例，进行说明。
如图2所示，该方法可以包括但不限于如下步骤：
步骤201，与接入网设备和/或，通过接入网设备与终端设备交互终端设备对应的上行定位参考信号的有效性。
本公开中，当接入网设备为终端设备配置的上行定位参考信号关联的TA timer超时，终端会释放接入网设备配置的上行定位参考信号，此时上行定位参考信号已失效，因此，接入网设备不能正确接收终端设备发送的上行定位参考信号，导致获取定位信息失败。
本公开中，为了防止由于上行定位参考信号失效，导致LMF获取信息失败的问题，定位管理功能LMF网元可以与接入网设备和/或终端设备，交互上行定位参考信号的有效性，使得LMF、接入网设备及终端设备对上行定位参考信号的有效性理解保持一致。从而LMF即可仅在确定上行定位参考信号的有效的情况下，再向基站请求上行定位参考信号的测量结果，例如上行定位参考信号的到达时间差。
可选的，上行定位参考信号的有效性，可以包括上行定位参考信号对应的TA timer值、或者上行定位参考信号已失效、或者上行定位参考信号的有效时长等。
需要说明的是，本公开中，可以由LMF向接入网设备指示上行定位参考信号的有效性信息，或者也可以由接入网设备向LMF指示上行定位参考信号的有效性信息，或者，LMF可以同时向接入网设备或通过接入网设备向终端设备指示上行定位参考信号的有效性信息，或者，LMF还可以接收接入网设备指示的上行定位参考信号的有效性信息，之后再通过接入网设备向终端设备指示该上行定位参考信号的有效性信息等等，本公开对此不做限定。
举例来说，接入网设备在为终端设备分配上行定位参考信号关联的TA timer值时，可以将此TA timer值发送给LMF，LMF接收到TA timer值后，即可开始计时，在计时时长大于TA timer值时，即可确定上行定位参考信号已失效。
或者，在上行定位参考信号失效时，接入网设备也可以向LMF发送上行定位参考信号已失效信息，LMF在接收到上行定位参考信号失效信息后，即可确定上行定位参考信号已失效。
或者，接入网设备可以在为终端设备分配的上行定位参考信号及上行定位参考信号有效时长时，将此上行定位参考信号有效时长信息发送给LMF，LMF接收到上行定位参考信号有效时长信息后，即可开始计时，在计时时长大于有效时长时，可以确定上行定位参考信号已失效。
或者，LMF还可以将上行定位参考信号的时间信息发送给接入网设备，之后，接入网设备即可参考上行定位参考信号的时间信息，确定上行定位参考信号对应的TA timer值。比如，接入网设备可以设置TA timer值大于时间信息，即可保证LMF可以在TA timer定时结束前，获取到定位信息。
其中，上行定位参考信号的时间信息可以包括：上行定位参考信号的持续时长、或者上行定位参考信号的定时提前量TA定时器timer的推荐值、或者请求上行定位参考信号测量结果的参考时长等，本公开对此不作限制。
或者，LMF还可以通过接入网设备向终端设备指示上行定位参考信号的时间信息，之后，终端设备可以根据上行定位参考信号的时间信息，确定上行定位参考信号对应的TA timer值。
可选的，终端设备还可以在TA timer计时结束时，通过接入网设备向LMF发送上行定位参考信号已失效的信息，由此，LMF在接收终端设备发送的用于指示上行定位参考信号已失效的信息后，即可确定上行定位参考信号已失效。
本公开中，LMF可以通过与接入网设备和/或，通过接入网设备与终端设备交互终端设备对应的上 行定位参考信号的有效性。从而可以避免获取定位信息失败的现象，进一步的提高了定位的可靠性。
请参见图3，图3是本公开实施例提供的一种定位的方法的流程示意图，该方法由核心网设备执行。本公开中，核心网设备可以为LMF网元，以下实施例以LMF网元为例，进行说明。
如图3所示，该方法可以包括但不限于如下步骤：
步骤301，向接入网设备发送第二指示信息，其中，第二指示信息用于指示时间信息。
本公开中，LMF可以向接入网发送新空口定位协议A(new radio position protocol A，NRPPa)定位信息请求消息(position information request)，来向接入网设备请求定位信息，之后，接入网设备可以通过NRPPa定位信息响应消息(position information response)向LMF返回定位信息。并在有定位需求时，再向接入网设备发送NRPPa测量结果请求消息(measurment request)来获取测量结果。
本公开中，LMF，可以根据发送NRPPa position information request和发送NRPPa measurment request的时间间隔，确定时间信息。
其中，上行定位参考信号的时间信息可以包括：上行定位参考信号的持续时长、或者上行定位参考信号的定时提前量TA定时器timer的推荐值、或者请求上行定位参考信号测量结果的参考时长等，本公开对此不作限制。
比如，LMF可以设置上行定位参考信号的TA timer的推荐值大于时间间隔，或者还可以将时间间隔，确定为上行定位参考信号测量结果的参考时长，从而保证LMF在请求测量结果时，上行定位参考信号依然有效，即LMF可以可靠获取到测量结果，进而对终端设备进行可靠、准确的定位。
可选的，LMF可以以独立的NRPPa消息将第二指示信息发送给接入网设备，或者，还可以通过NRPPa定位信息请求消息，向接入网设备发送第二指示信息。比如，可以利用NRPPa定位信息请求消息中的预设比特bit表示第二指示信息，进而接入网设备在接收到NRPPa定位信息请求消息后，即可对NRPPa定位信息请求消息进行解析，以根据预设bit的取值确定第二指示信息。
接入网设备在确定第二指示信息后，即可根据第二指示信息中指示的时间信息，配置上行定位参考信号对应的TA timer的值。比如，第二指示信息指示的时间信息为上行定位参考信号的TAtimer的推荐值，则接入网设备可以设置TA timer的值大于或等于TA timer的推荐值。或者，第二指示信息指示的时间信息为上行定位参考信号的持续时长，则接入网设备可以设置TA timer的值大于或等于上行定位参考信号的持续时长等等，从而进一步的保证LMF再请求测量结果时，上行定位参考信号处于有效状态。
本公开中，LMF向接入网设备发送，用于指示上行定位参考信号的时间信息的第二指示信息。由此，接入网设备可以根据第二指示信息，确定终端设备的TA timer值，从而避免获取定位信息失败的现象，进一步的提高了定位的可靠性。
请参见图4，图4是本公开实施例提供的一种定位的方法的流程示意图，该方法由核心网设备执行。本公开中，核心网设备可以为LMF网元，以下实施例以LMF网元为例，进行说明。
如图4所示，该方法可以包括但不限于如下步骤：
步骤401，接收接入网设备发送的第一指示信息，其中，第一指示信息用于指示上行定位参考信号有效性的信息。
其中，上行定位参考信号的有效性，可以包括上行定位参考信号对应的TA timer值、或者上行定位参考信号已失效、或者上行定位参考信号的有效时长等。本公开对此不作限制。
本公开中，LMF可以通过NRPPa position information response，接收接入网设备发送的第一指示信息。举例来说，接入网设备可以将第一指示信息，配置在NRPPa定位信息响应消息中，当LMF通过新空口定位协议NRPPa，向接入网设备发送定位信息请求消息后，接入网设备即可将配置后的NRPPa定位信息响应消息，返回给LMF。
可选的，LMF还可以通过NRPPa定位信息更新消息，接收接入网设备发送的第一指示信息。例如，接入网设备可以将第一指示信息，配置在NRPPa定位信息更新消息中，当LMF通过新空口定位协议NRPPa，向接入网设备发送定位信息更新请求消息后，接入网设备即可将配置后的NRPPa定位信息更新消息，发送给LMF。
可选的，若第一指示信息指示的为上行定位参考信号已失效，则LMF还可以通过NRPPa定位信息失败消息，接收接入网设备发送的第一指示信息。例如，接入网设备可以将第一指示信息，配置在NRPPa定位信息失败消息中，当LMF通过新空口定位协议NRPPa，向接入网设备发送定位信息请求消息后，在定位失败的情况下，接入网设备即可将配置后的NRPPa定位信息失败消息，发送给LMF。
本公开中，LMF可以接收接入网设备发送的第一指示信息，其中，第一指示信息用于指示上行定位参考信号有效性的信息。从而可以避免获取定位信息失败的现象，进一步的提高了定位的可靠性。
请参见图5，图5是本公开实施例提供的一种定位的方法的流程示意图，该方法由核心网设备执行。 本公开中，核心网设备可以为LMF网元，以下实施例以LMF网元为例，进行说明。
如图5所示，该方法可以包括但不限于如下步骤：
步骤501，接收接入网设备发送的第一指示信息，其中，第一指示信息用于指示上行定位参考信号有效性的信息。
其中，上行定位参考信号的有效性，可以包括上行定位参考信号对应的TA timer值、或者上行定位参考信号已失效、或者上行定位参考信号的有效时长等。本公开对此不作限制。
本公开中，LMF可以通过NRPPa position information response，接收接入网设备发送的第一指示信息。举例来说，接入网设备可以将第一指示信息，配置在NRPPa定位信息响应消息中，当LMF通过新空口定位协议NRPPa，向接入网设备发送定位信息请求消息后，接入网设备即可将配置后的NRPPa定位信息响应消息，返回给LMF。
可选的，LMF还可以通过NRPPa定位信息更新消息，接收接入网设备发送的第一指示信息。例如，接入网设备可以将第一指示信息，配置在NRPPa定位信息更新消息中，当LMF通过新空口定位协议NRPPa，向接入网设备发送定位信息更新请求消息后，接入网设备即可将配置后的NRPPa定位信息更新消息，发送给LMF。
可选的，若第一指示信息指示的为上行定位参考信号已失效，则LMF还可以通过NRPPa定位信息失败消息，接收接入网设备发送的第一指示信息。例如，接入网设备可以将第一指示信息，配置在NRPPa定位信息失败消息中，当LMF通过新空口定位协议NRPPa，向接入网设备发送定位信息请求消息后，在定位失败的情况下，接入网设备即可将配置后的NRPPa定位信息失败消息，发送给LMF。
步骤502，响应于当前时刻与接收第一指示信息的时刻间的时间间隔大于TA timer值或有效时长，向接入网设备发送终端设备上行定位参考信号获取请求。
本公开中，LMF在接收到接入网设备发送的第一指示信息后，可以对第一指示信息进行解析，以确定上行定位参考信号对应的TA timer值或有效时长。在有定位需求时，首先根据第一指示信息指示的有效性信息，确定当前时刻上行定位参考信号是否有效。
可选的，在当前时刻与接收第一指示信息的时刻间的时间间隔大于TA timer值或有效时长、或者第一指示信息，指示上行定位参考信号已失效的情况下，可以确定上行定位参考信号失效，因此，LMF可以向接入网设备发送终端设备上行定位参考信号获取请求，以获取新的上行定位参考信号。
步骤503，响应于确定上行定位参考信号当前有效，向接入网设备发送定位参考信号的测量结果获取请求。
本公开中，LMF在当前时刻与接收第一指示信息的时刻间的时间间隔小于TA timer值或有效时长，或者，第一指示信息指示上行定位参考信号有效的情况下，即可确定上行定位参考信号有效，之后，LMF可以向接入网设备发送定位参考信号的测量结果获取请求，以获取定位参考信号的测量结果，从而确定终端设备的位置信息。
本公开中，LMF接收接入网设备发送的，用于指示上行定位参考信号有效性的信息的第一指示信息后，在有定位需求时，即可首先根据第一指示信息，确定当前时刻上行定位参考信号是否有效，并在上行定位参考信号已失效的情况下，向接入网设备发送终端设备上行定位参考信号获取请求，则上行定位参考信号当前有效的情况下，向接入网设备发送定位参考信号的测量结果获取请求。由此，不仅可以避免在上行定位参考信号已失效的情况下，浪费获取测量结果的信令，而且可以减少定位时间，提高定位速度。
请参见图6，图6是本公开实施例提供的一种定位的方法的流程示意图，该方法由核心网设备执行。本公开中，核心网设备可以为LMF网元，以下实施例以LMF网元为例，进行说明。

可选的，上行定位参考信号的有效性，可以包括上行定位参考信号对应的TA timer值、或者上行定位参考信号已失效、或者上行定位参考信号的有效时长等。

举例来说，接入网设备在为终端设备分配上行定位参考信号关联的TA timer值时，可以将此TA timer值发送给LMF，LMF接收到TA timer值后，即可开始计时，在计时时长大于TA timer值时，即可确定上行定位参考信号已失效。
或者，在上行定位参考信号失效时，接入网设备也可以向LMF发送上行定位参考信号已失效信息，LMF在接收到上行定位参考信号失效信息后，即可确定上行定位参考信号已失效。
或者，接入网设备可以在为终端设备分配的上行定位参考信号及上行定位参考信号有效时长时，将此上行定位参考信号有效时长信息发送给LMF，LMF接收到上行定位参考信号有效时长信息后，即可开始计时，在计时时长大于有效时长时，可以确定上行定位参考信号已失效。
或者，接入网设备还可以接收LMF发送的上行定位参考信号的时间信息，之后，接入网设备即可参考上行定位参考信号的时间信息，确定上行定位参考信号对应的TA timer值。比如，接入网设备可以设置TA timer值大于时间信息，即可保证LMF可以在TA timer定时结束前，获取到定位信息。
其中，上行定位参考信号的时间信息可以包括：上行定位参考信号的持续时长、或者上行定位参考信号的定时提前量TA定时器timer的推荐值、或者请求上行定位参考信号测量结果的参考时长等，本公开对此不作限制。

本公开中，LMF，可以根据发送NRPPa position information request和发送NRPPa measurment request的时间间隔，确定时间信息。
其中，上行定位参考信号的时间信息可以包括：上行定位参考信号的持续时长、或者上行定位参考信号的定时提前量TA定时器timer的推荐值、或者请求上行定位参考信号测量结果的参考时长等，本公开对此不作限制。

可选的，LMF可以以独立的NRPPa消息将第二指示信息发送给接入网设备，或者，还可以通过NRPPa定位信息请求消息，向接入网设备发送第二指示信息。比如，可以利用NRPPa定位信息请求消息中的预设比特bit表示第二指示信息，进而接入网设备在接收到NRPPa定位信息请求消息后，即可对NRPPa定位信息请求消息进行解析，以根据预设bit的取值确定第二指示信息。
步骤902，根据时间信息，确定终端设备对应的TA timer的值。
本公开中，接入网设备在确定第二指示信息后，即可根据第二指示信息中指示的时间信息，配置上行定位参考信号对应的TA timer的值。比如，第二指示信息指示的时间信息为上行定位参考信号的TA timer的推荐值，则接入网设备可以设置TA timer的值大于或等于TA timer的推荐值。或者，第二指示信息指示的时间信息为上行定位参考信号的持续时长，则接入网设备可以设置TA timer的值大于或等于上行定位参考信号的持续时长等等，从而进一步的保证LMF再请求测量结果时，上行定位参考信号处于有效状态。
