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,并且只支持基于UE的定位完整性。基于UE的定位完整性,是由UE来确定自身的定位完整性。具体的,UE确定PL(保护等级)并将PL上报给LMF网元。
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(HorizontalPL,HPL)或垂直保护等级(VerticalPL,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)。
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。
目前仅标准化了基于UE的定位完整性,本申请提供的方法引入了基于LMF网元的定位完整性。即,由LMF网元确定对终端定位时的定位完整性。

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。
