首先，对本申请实施例涉及的相关技术进行介绍：
对于定位技术，NR中引入了定位完整性(positioning integrity)的概念。定位完整性用于衡量定位系统提供的位置相关数据的准确性的可信度，以及在定位系统不满足预定操作条件时，向定位服务(Location Service，LCS)客户提供及时有效警告的能力。
目前标准化了A-GNSS定位技术的定位完整性，主要包括LMF向UE提供错误源(辅助信息)的完整性参数，包括如表1所示的参数：
表1：Mapping of Integrity Parameters(完整性参数的映射)
Figure PCTCN2022126685-appb-000001
Figure PCTCN2022126685-appb-000002
Figure PCTCN2022126685-appb-000003
UE根据上述参数进行定位完整性，并向LMF上报定位完整性的结果。
相关技术中，将研究RAT-dependent(Radio Access Technology-dependent， 依赖于无线电接入技术)定位技术的定位完整性问题，例如UL-TDOA(Uplink Time Difference Of Arrival，上行到达的时间差)，DL-TDOA(Downlink Time Difference Of Arrival，下行到达的时间差)，UL-AOA(Uplink Angles of Arrival，上行链路到达角)，DL-AOD(Downlink Angle-of-Departure，下行离开角)、multi-RTT(Multiplecell-Round Trip Time，多小区往返时间)等定位技术。
其中，对于下行定位技术，可能的错误源信息包括：
·TRP(Transmit/Receive Point，传输接收点)的位置；
·TRP之间的时间同步(NR-RTD-Info，NR-Relative Time Difference-Info，新空口-相对时间差-信息)；
·DL-PRS(DownLink-Positioning Reference Signal，下行定位参考信号)的beam(波束)信息；
·DL-PRS的boresight direction(视轴方向)；
·UE的测量，例如RSTD(Reference Signal Time Difference，参考信号时间差)，UE Rx-Tx timing difference(接收发送时间差)；
·UE的定时。
其中，TRP也以表示为接入网设备，即，错误源信息可以包括：接入网设备的位置、接入网设备之间的时间同步、DL-PRS的波束信息、DL-PRS的视轴方向、UE的测量、UE的定时中的至少一个。
UE根据错误源信息以及网络设备提供的其他参数可以完成positioning integrity的计算。即当UE计算得到的PL不满足下述不等式，UE就向LMF上报PL(保护等级)，以向LMF提供告警。
PL(保护等级)是指定位误差(Position Error，PE)的统计上限。PL需要确保单位时间内真实误差大于AL(Alert Limit，警戒限制)且PL小于等于AL的持续时间超过TTA(Time-To-Alert，警戒时间)的概率，要小于要求的TIR(Target Integrity Risk，目标完整性风险)。即PL需要满足以下不等式：
每单位时间[((PE>AL)&(PL<＝AL))长于TTA]的概率<要求的TIR。
当PL限定了水平面或垂直轴上的定位误差时，它被分别称为水平保护等级(Horizontal PL，HPL)或垂直保护等级(Vertical PL，VPL)。
目标完整性风险(TIR)：为定位错误超过警戒限制(AL)的概率，而没有在要求的警戒时间(TTA)内警告用户。TIR通常被定义为每单位时间(例如，每小时，每秒钟或每一个独立时间样本)的概率。
警戒限制(AL)：使定位系统能够用于预定应用的最大允许定位误差。如果定位误差超出了AL范围，应宣布定位系统在预定应用中不可用，以防止丢失定位完整性。当AL在水平面或垂直轴上限制定位误差时，它分别被称为水平警报 限制(Horizontal AL，HAL)或垂直警报限制(Vertical AL，VAL)。其中，PL不等式对AL的所有值都有效。
TTA(警戒时间)：从定位错误超过警报限制(AL)到提供定位完整性的功能发出相应警报的最大允许时间。
其中，TIR为LMF为终端配置的。AL、TTA为终端自行确定的，例如，从预定应用获取。终端根据上述不等式确定PL，并向LMF网元上报PL。

终端101的数量通常为多个，每一个接入网设备102所管理的小区内可以分布一个或多个终端101。终端101可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
接入网设备102是一种部署在接入网中用以为终端101提供无线通信功能的装置。接入网设备102可以包括各种形式的宏基站，微基站，中继站，接入点。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在第五代(5th Generation，5G)移动通信技术NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端101提供无线通信功能的装置统称为接入网设备。接入网设备102与终端101之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备102的数量可以有多个，两个邻近的接入网设备102之间也可以通过有线或者无线的方式进行通信。终端101可以在不同的接入网设备102之间进行切换，也即与不同的接入网设备102建立连接。可选的，接入网设备具有至少一个TRP，接入网设备通过TRP与终端进行通信。
核心网设备103的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。接入网设备102和核心网设备103可统称为网络设备，示例性的，本申请实施例中的网络设备可指接入网设备。核心网设备103与接入网设备102之间通过某种技术相互通信，通过接入网设备102，终端101和核心网设备103之间可以建立通信关系。示例性的，本申请实施例中的核心网设备包括LMF网元。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
可选的，定位完整性包括基于终端的定位完整性和基于LMF网元的定位完整性。
一、在基于终端的定位完整性中，是由LMF网元向终端提供辅助信息，以便于终端基于辅助信息计算定位完整性。
二、在基于LMF网元的定位完整性中，LMF网元可以通过终端和/或基站提供的信息，计算终端的定位完整性。
本申请实施例针对上述两种定位完整性的计算方式，分别提供了多个示例性实施例，以使非计算方(LMF网元或终端)获知定位完整性告警的原因。
一、基于终端的定位完整性。

可选的，本申请实施例提供的方法应用于下行定位或上下行相结合定位场景中。
对于下行定位或上行下行相结合定位，终端向LMF网元发送定位完整性的错误原因。可选的，UE通过LPP(Long Term Evolution Positioning Protocol，长期演进定位协议)消息向LMF网元上报错误原因，例如，LPP消息可以是LPP提供位置信息(LPP provide location information)消息。
可选地，该定位完整性包括以下至少之一：

可选地，定位完整性包括PL。PL包括HPL和/或VPL。
定位完整性是根据PE、TIR、AL、TTA确定的。
其中，PE包括终端的定位误差分布。PE的具体获取方式和数据形式由终端实现。例如，PE包括终端在一段时间内通过定位系统得到的位置与真实位置的误差分布情况。终端可以根据新的定位结果更新PE。再如，终端可以从应用服 务器获取终端的定位误差信息，从而确定终端的PE。
TIR为单位时间内定位系统定位错误超过AL的概率。TIR可以是由LMF网元配置的，也可以是由终端确定的，也可以是终端从应用服务器获取的。例如，如果终端向LMF发送TIR，则终端可以从应用服务器获取信息从而确定TIR。又例如，对于基于UE的定位完整性，LMF为终端配置TIR，指示终端在单位时间内定位系统定位错误超过AL的概率不应该超过该TIR。
AL是使定位系统能够用于预定应用的最大允许定位误差。AL为定位系统能够用于预定应用(应用服务器对应的应用)的最大允许定位误差。AL由终端确定，或者，AL由终端从应用服务器获取，应用服务器根据预定应用的需求设置有AL，以使定位系统的定位误差需要小于AL。
