  • Figure 1 is a schematic diagram of the location provision process. As shown in the figure, for the network QoS mechanism, the existing process of providing QoS requirements through LPP is:
  • Step 101 Based on the requested location service, the LMF broadcasts the QoS required by the corresponding location service to the terminal through the request location information (request location information) message in the LPP protocol;
  • Step 102 The terminal receives the QoS index brought by the LPP message, and selects an appropriate positioning method according to the QoS requirement in the UE-Based (UE benchmark; UE: User Equipment) scenario to meet the QoS index requirement. Finally, the terminal sends the calculated location to the network through providelocationinformation (providing location information), and indicates the deviation that satisfies the QoS index.

If the positioning error exceeds the ProtectionLevel threshold in any dimension or equivalent dimension, the operation will become very dangerous. Therefore, when the system considers that the application becomes unavailable, it starts to warn to protect against loss of integrity.
  • Reliability requirement indication including multiple dimensions such as horizontal and vertical:
  • the disadvantage of the related technology is that, as mentioned above, there is no concept of positioning service integrity under the current 3GPP architecture. Under the current technology, when the accuracy of the positioning service meets the QoS index requirements, but sometimes the position estimation generates a very large error, the related technology cannot solve this situation. In the positioning business scenario that affects the safety of life and property and brings legal liabilities, if the positioning error is too large at one time, it may bring serious impacts and cause bad consequences. Therefore, relevant technical mechanisms need to be improved to limit the occurrence of extreme points and avoid such incidents. Among them, the extreme point of the position estimation refers to: the distance between the calculated position and the real position exceeds the preset threshold T, which is called the extreme point.
  • the threshold T value is 10 meters
  • the actual position is at point A
  • the calculated position is at point B
  • the distance between point A and point B is greater than the threshold T10 meters.

  • the existing positioning mechanism only meets the requirements of positioning accuracy, that is, the positioning service only supports the positioning accuracy that is met under a certain confidence interval. It does not introduce the integrity of the service quality requirements.
  • “Integrity” is a capability of the positioning enhancement system, which is suitable for various scenarios that affect the safety of life and property and bring legal liabilities. As 5G systems are oriented to vertical industries, positioning services based on mobile communication networks will be used in scenarios such as autonomous driving and industrial Internet of Things. In these scenarios, there are not only requirements for positioning accuracy, but also further requirements for the range of positioning errors.
  • the terminal After the integrity function is introduced, the terminal can be informed of the tolerable range of position errors for the positioning service according to the requirements of different scenarios, and the extremely bad points of these position estimates will be restricted to avoid the loss of life and property caused by positioning system errors. , To avoid legal liability caused by position error; when the risk exceeds the control range, the system will accurately and timely alert the user to fully protect the safety of the user. If the integrity is not required in the QOS of the positioning service, the terminal and the location server that calculate the position cannot obtain the index requirements for supporting integrity, and the integrity of the positioning service of the mobile communication network cannot be achieved. Based on this, the present disclosure implements The technical solution provided in the example will solve the problem of how to set and feedback to meet the integrity QoS index requirements.

图1为本公开实施例中位置提供流程示意图；

具体实施方式
发明人在发明过程中注意到：
下面对LPP(定位协议，LTE Positioning Protocol；LTE：长期演进，Long Term Evolution)协议中现有QoS(服务质量，Quality of Service)定义进行简要说明。需要注意的是，LPP协议可能适用于多种网络，例如LPP协议既用于5G NR网络，也用于LTE网络，也即，本公开实施例所提供的内容也适用于LPP协议所运用的背景之中。
LPP协议中定义了定位业务的QoS要求，由LMF(定位管理实体，Location Management Function)位置服务器通知给终端。QoS中包含了对定位精度的要求，包括在一定置信区间(confidence)下，水平位置的精度要求。以及一定置信区间下，垂直位置的精度要求。
图1为位置提供流程示意图，如图所示，对于网络QoS机制，现有通过LPP提供QoS要求的流程是：
步骤101、LMF将基于所请求的定位业务，播发对应的定位业务所需QoS通过LPP协议中requestlocationinformation(请求位置信息)消息给终端；
步骤102、终端接收到LPP消息带来的QoS指标，在UE-Based(UE基准；UE：用户设备，User Equipment)场景下根据QoS要求选择合适的定位方法，满足QoS指标要求。最后终端通过providelocationinformation(提供定位信息)将计算的位置发给网络，并指示满足QoS指标的偏差。
步骤103、UE-Assisted(UE辅助)的终端在辅助定位测量中，通过providelocationinformation给网络，提供测量量，帮助位置服务器LMF进行位置计算。
下面对“完好性”的指标定义进行简要说明。
位置估计的误差控制一定范围要求之内的指标为完好性指标要求，通常有如下几类参数：
完好性水平位置保护值(HorizontalProtectionLevel)：
指示水平位置估计误差，要求水平位置估计误差大于PL(位置保护值， ProtectionLevel)的概率应该低于风险要求Irisk值，P(ε>PL)<Irisk。
完好性垂直位置保护值(VerticalProtectionLevel)：
指示垂直位置误差上限，要求垂直位置估计误差大于PL的概率应该低于风险要求Irisk值，P(ε>PL)<Irisk。
其中ε是实际的位置估计误差，Irisk定义见下：
完好性风险要求Integrity risk(Irisk)：
完好性风险是指定位误差超过了容忍限度的概率。
水平位置告警门限(Horizontal Alert Limit)。
垂直位置告警门限(Vertical Alert Limit)：
系统能够正常工作时所允许的最大位置估计误差值(水平位置和垂直位置)。如果定位误差在任何维度或者等效维度下超过了ProtectionLevel门限，操作将会变得很危险。因此系统认为对该应用变得不可用时，就开始告警，以此来保护完好性的损失。
水平位置告警有效时间(Horizontal Time to Alert)；
垂直位置告警有效时间(Vertical Time to Alert)；
可靠性要求指示(Authentication Flag)，包含水平和垂直等多个维度：
要求该业务支持完好性功能的指示。
相关技术的不足在于，如前所述，目前3GPP架构下并没有定位业务完好性的概念。当前技术下，当定位业务的精度满足QoS指标要求，但是某些时候位置估计产生非常大的误差，相关技术是无法解决此种情形的。在影响生命财产安全，会带来法律责任的定位业务场景下，如果一次定位误差过大，将可能带来严重影响、造成恶劣后果。因此需要对相关技术机制进行完善，限制极差点的产生，避免此类事件的发生。其中，位置估计的极恶劣点是指：计算出来的位置与真实位置之间的距离超出了预设的门限T，称之为极恶劣点。比如，门限T值为10米，实际位置在点A，计算出来的位置在点B，点A与点B之间的距离大于门限T10米，这样的位置即为极恶劣点，这会带来难以预料的后果。例如在工业物联网机器自动起吊设备工作时，会因位置误差超过预设门限T造成了经济损失或者人员伤亡。
也即，现有的定位机制只满足了定位精度的要求，即定位业务只支持在 一定置信区间下，所满足的定位精度。并没有引入完好性的服务质量要求。“完好性”是定位增强系统的一种能力，适用于影响生命财产安全，会带来法律责任的各类场景。由于5G系统面向垂直行业，基于移动通信网络的定位业务将在诸如自动驾驶、工业物联网等场景下使用时。在这些场景下，不仅对定位精度有要求，而且对定位误差的范围也有了更进一步的要求。
引入了完好性功能后，可以根据不同场景要求，告知终端该定位业务对位置误差的可容忍范围，将对这些位置估计的极恶劣点进行限制，避免因定位系统误差，带来的生命财产损失，避免因位置误差带来的法律责任；当风险超出控制范围时，系统将准确、及时向用户告警，充分保障使用者安全。如果不在定位业务中的QOS中对完好性进行指标要求，那么计算位置的终端和位置服务器无法获取支持完好性的指标要求，就无法实现移动通信网络定位业务的完好性，基于此，本公开实施例中提供了的技术方案将解决如何设置并反馈满足完好性QoS指标要求问题。
下面结合附图对本公开的具体实施方式进行说明。
在说明过程中，将分别从UE与网络侧的实施进行说明，然后还将给出二者配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当UE与网络侧分开实施时，其也各自解决UE侧、网络侧的问题，而二者结合使用时，会获得更好的技术效果。
图2为网络侧的定位业务处理方法实施流程示意图，如图所示，可以包括：
步骤201、LMF接收定位业务请求；
步骤202、LMF通过LPP协议向终端发送包含有完好性的QoS指标要求；
步骤203、LMF根据终端返回的测量值进行位置估计以及完好性估计，其中，所述测量值是终端通过辅助测量功能以及完好性辅助监测获取的测量值。
图3为终端侧的定位业务处理方法实施流程示意图，如图所示，包括：
步骤301、终端接收LMF通过LPP协议发送的包含有完好性的QoS指标要求；
步骤302、终端根据所述包含有完好性的QoS指标要求执行辅助测量功能以及完好性辅助监测后获取测量值；
步骤303、终端向LMF返回所述测量值，其中，所述测量值是终端通过辅助测量功能以及完好性辅助监测获取的测量值。
在一些可选的实施例中，包含有完好性的QoS指标，包括以下信息之一或者其组合：
完好性风险要求(Integrity risk，简称Irisk))；
水平位置告警门限(Horizontal Alert Limit)；
垂直位置告警门限(Vertical Alert Limit)；
水平位置告警有效时间(Horizontal Time to Alert)；
垂直位置告警有效时间(Vertical Time to Alert)；
可靠性要求指示(Authentication Flag)。
实施例中，会使用缩写AL(Alert Limit)，表示水平位置告警门限与垂直位置告警门限；使用缩写TTA(Time to Alert)，表示水平位置告警有效时间与垂直位置告警有效时间。
具体的，定位业务的完好性指的是定位业务信任级别的度量。当系统不能够满足预先设定的指标要求时，它能够给终端用户提供及时有效的告警。
当发起定位业务请求时，位置服务器根据业务类型，通过LPP协议发送包含关于完好性的QoS指标要求给终端。在测量的情况下，这些QoS指标可应用于位置服务器的位置估计，假设测量是唯一的误差源，服务器可以通过目标设备提供的测量值来进行位置估计。
终端接收到关于完好性的指标要求后，分别在辅助测量和位置计算过程中，执行完好性功能，最终实现QoS要求的完好性指标。

需要注意的是，所述第一消息和第二消息可以是相同消息或不同消息，可以在相同的或不同的信令中携带。例如，包含有完好性的QoS指标要求可以通过LPP信令请求位置信息携带的，也可以通过其他消息携带；终端返回的测量值可以通过LPP信令提供定位信息携带的，可以通过其他消息携带，本申请不做具体限定。
在一些可选的实施例中，完好性辅助监测获取的测量值，包括：

具体的，在接收QoS及测量阶段，支持UE-Assisted能力的终端、支持UE-based能力的终端都是一样的，需要获取QoS值，需要提供测量值给网络。不同在于，支持UE-based能力的终端还需要根据QoS值计算PL，判断系统是否可靠，然后发送结果给网络。
下面以实例进行说明。
实施例1
本例中，所述终端是支持UE-Assisted能力的终端，终端根据所述包含有 完好性的QoS指标要求中的完好性风险要求Irisk、水平位置告警门限、垂直位置告警门限、可靠性要求指示authentication flag、水平位置告警有效时间、垂直位置告警有效时间其中之一或者其组合执行辅助测量功能以及完好性辅助监测后获取测量值。
定位服务器接收到来自定位客户端的定位业务请求时，按如下方式执行：
1、服务器LMF根据业务类型，选择设置对应的QoS指标要求；例如包括定位精度要求和定位完好性指标要求。
2、定位服务器通过LPP信令RequestLocationInformation，发送QoS，携带有关完好性的要求。在此消息中携带的完好性指示信息，可以是以下信息中的一种或者多种组合，具体的，例如要求完好性水平位置保护阈值不能超过1米，风险要求控制在90％以内，这意味着90％概率内定位水平误差不能超过1米。一旦超过1米了，系统将不可靠，即不再采用计算出来的位置。
完好性风险要求；
水平位置预警门限；
垂直位置预警门限；
水平位置告警有效时间；
垂直位置告警有效时间；
可靠性要求指示，包含水平和垂直等多个维度。
3、当仅支持UE-Assisted能力的UE收到来自服务器的LPP信令RequestLocationInformation时，读取QoS中有关完好性的要求，根据QoS中Irisk、AL、authentication flag、TTA等参数，结合网络播发的辅助数据及其完好性指示，在终端侧执行辅助测量功能并支持完好性辅助监测。
4、当仅支持UE-Assisted能力的UE完成完好性功能监测和辅助测量，通过LPP协议ProvideLocationInformation提供完好性相关辅助测量值给网络。例如当在辅助测量的某些信号或系统处于不可靠情况下，测量出来的值不可靠。因此上报测量值的同时携带完好性告警指示分量，提示系统哪些测试分量进入不可靠状态，协助网络服务器进行位置计算以及完好性PL的计算。
在一些可选的实施例中，PL是UE或者LMF根据测量值计算出来的，不需要在QoS中体现。
实施例2:
本例中，所述终端是支持UE-based能力的终端，终端根据所述包含有完好性的QoS指标要求中的位置保护值PL、完好性风险要求Irisk、水平位置告警门限、垂直位置告警门限、可靠性要求指示authentication flag其中之一或者其组合执行辅助测量功能以及完好性辅助监测后获取测量值。
定位服务器接收到来自定位客户端的定位业务请求时，按如下方式执行：
1、服务器LMF根据业务类型，选择设置对应的QoS指标要求；例如包括定位精度要求和定位完好性要求。
2、定位服务器通过LPP信令RequestLocationInformation，发送QoS，携带有关完好性的要求。在此消息中携带的完好性指示信息，可以是以下信息中的一种或者多种组合，具体的，例如通过authentication flag指示要求进行完好性保护，风险要求控制在99.9％以内，水平告警门限为0.16米，垂直告警门限为0.08米，意味着在99.9％的测量点里面，水平位置的定位误差不能超过0.2米，垂直误差不能超过0.1米。一旦水平误差持续时间超过水平位置告警有效时间Time to Alert，垂直误差持续时间超过垂直位置告警有效时间Time to Alert，系统将不可靠，即不能使用计算出来的位置。如果计算出来的水平位置误差在TTA时间内超过水平预警门限0.16米，或者垂直位置误差在TTA时间内超过预警门限0.08米，则说明系统到达临界点，终端将通过误差进行预警。

4、当支持UE-based能力的UE完成了位置计算、完好性水平位置保护值和完好性垂直位置保护值计算后，终端将计算出的结果PL与接收到的QoS完好性参数AL要求进行对比，如果在TTA时间内PL值超过了AL，则认为此时UE定位计算不再可靠。例如计算出来的水平位置误差在TTA时间内超过水平预警门限0.16米，或者垂直位置误差在TTA时间内超过预警门限0.08米，则说明系统到达临界点，终端将在该消息中通知服务器，该次计算位置估计不可靠。那么该UE将通过LPP信令中ProvideLocationInformation消息，将计算后的位置信息发送给LMF，同时在此消息中反馈完好性满足度反馈，指示本次计算出的位置对应的完好性水平、垂直位置保护值超过了规定门限，指示目前终端定位系统不再可靠，并上报计算后的完好性保护值PL。
