请参考图2，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图2所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home  Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于：蜂窝移动通信系统中的手机终端等UE，以及网络侧设备，如基站等接入网设备，以及核心网等。
在5G蜂窝移动通信系统，无论是否有5G信号的覆盖，都可以进行测距服务。如图3a所示，两个UE均处于5G信号的覆盖下进行测距；如图3b所示，两个UE中的一个UE处于5G信号的覆盖下进行测距；如图3c所示，两个UE中的两个UE均处于5G信号的覆盖之外进行测距。
为了提高测距精度，协作测距客户端，即测距请求端可以采用协作测距对目标UE进行测距。具体而言，协作测距利用多个不同于测距请求端的辅助UE对同一目标UE进行测距。并通过聚合这些中间测距结果获得最终测距结果。
协作测距过程中，测距请求端可以在未经目标UE许可的情况下获取目标UE的高精度距离信息和高精度方向信息，从而导致目标UE位置隐私泄露。
因此，如何保护目标UE在协同测距过程中的位置隐私，是亟待解决的问题。
如图4所示，本示例性实施例提供一种协作测距方法，可以被蜂窝移动通信系统的测距服务器RS执行，包括：
步骤401：接收来自测距请求端的协作测距请求消息，所述协作测距请求消息请求针对目标UE进行协作测距；
步骤402：至少根据所述目标UE的隐私配置信息，确定是否进行所述协作测距。
本发明实施例方法可以用于但不限于核心网的测距服务器RS。RS可以用于对UE的测距服务进行管理。
测距请求端可以是请求对目标UE进行测距，获取测距请求端与目标UE的测距结果，即相对位置关系的UE。这里，测距结果包括：距离和/或方向等。
测距请求端可以向RS发送协作测距请求，通过协作测距的方式确定与目标UE的测距结果。
这里，协作测距可以包括聚合多个辅助UE与目标UE的测距结果，确定测距请求端与目标UE的测距结果。例如，可以结合多个已知位置辅助UE对目标UE进行测距，基于得到的目标UE和多个辅助UE直接的距离和/或方向值，确定距离和/或方向值的误差。进而对测距请求端与目标UE的距离和/或方向进行补偿。还可以采用三角定位法等，通过多个辅助UE与目标UE的测距结果，确定目标UE的坐标，对测距请求端与目标UE的距离和/或方向进行修正。
由于协作测距综合多个辅助UE与目标UE的测距结果确定测距请求端与目标UE的测距结果，因此，可以提高测距请求端与目标UE的测距结果的精度。
目标UE的隐私配置信息可以是预设于核心网设备中的，也可以是目标UE发送给核心网设备的。
隐私配置信息可以用于供RS确定是否能够针对目标UE进行协作测距，即是否允许确定多个辅助UE与目标UE的测距结果，并聚合得到测距请求端与目标UE的测距结果。
隐私配置信息可以指示是否允许针对目标UE进行协作测距，也可以指示允许针对目标UE进行协作测距的条件、还可以指示不允许针对目标UE进行协作测距门限等。
在一个实施例中，所述方法还包括:
接收来自统一数据管理(UDM，Unified Data Management)的所述目 标UE的所述隐私配置信息。
测距请求端向RS发送协作测距请求，请求对目标UE进行测距的协作测距服务。RS可以从UDM获得目标UE的隐私配置信息。
示例性的，RS可以向目标UE的UDM调用Nudm_SDM_Get服务操作，以获得由目标UE的隐私配置信息。UDM返回目标UE的隐私配置信息。
在一个实施例中，所述目标UE的所述隐私配置信息，是采用所述目标UE的通用公共用户标识(GPSI，Generic Public Subscription Identifier)和/或用户永久标识(SUPI，Subscriber Permanent Identifier)标识的。
UDM可以将目标UE的隐私配置信息存储在统一数据存储(UDR，Unified Data Repository)中。并采用目标UE的标识进行标识，这里，目标UE的标识可以包括：GPSI和/或SUPI。
协作测距请求中可以包括目标UE的标识，用于指示请求进行协作测距的目标UE。RS接收到协作测距请求后，可以基于目标UE的标识从UDM获取目标UE的隐私配置信息，UDM可以返回目标UE的隐私配置信息和目标UE的标识。
通过GPSI和/或SUPI标识隐私配置信息，可以区分不同目标UE的隐私配置信息，减少隐私配置信混淆的情况。不同目标UE具有各自的隐私配置信息，满足不同目标UE的不同的隐私需求。
如此，根据隐私配置信息确定是否针对目标UE进行协作测距。通过对是否针对目标UE进行协作测距进行控制，实现对目标UE的精确测距结果的获取进行管控，进而提高对目标UE位置隐私的保护。
在一个实施例中，所述隐私配置信息，包括：
协作测距隐私指示，用于指示是否允许针对所述目标UE进行所述协作测距。
协作测距隐私指示可以是通过一个或多个比特位显性地指示的。例如， 协作测距隐私指示可以占用隐私配置信息的一个或多个比特位，通过不同的值指示允许针对目标UE进行协作测距，或者不允许针对目标UE进行协作测距。
协作测距隐私指示也可以是隐含指示的。隐私配置信息可以通过携带的不同信息隐含指示是否允许针对所述目标UE进行协作测距。
示例性的，隐私配置信息可以通过是否指示进行协作测距的测量要求进行隐含指示。测量要求可以包括指定进行协作测距的辅助UE数量等。当隐私配置信息指示有测量要求时，可以隐含指示允许进行协作测距，并且需要满足该测量要求。当隐私配置信息未指示测量要求时，可以隐含指示不允许进行协作测距。
如此，通过协作测距隐私指示对是否针对目标UE进行协作测距进行控制，实现对目标UE的精确测距结果的获取进行管控，进而提高对目标UE位置隐私的保护。
在一个实施例中，所述隐私配置信息，还用于指示进行所述协作测距的测量要求。
测量要求也可以是针对协作测距的测量结果的要求，例如可以规定测量结果的精度要求等。
测量要求也可以针对目标UE的位置、时间等进行限制。
这里，测量要求可以是针对测距请求端的要求，例如，针对测距请求端的类型要求等。可以允许指定类型的测距请求端进行协作测距。这里，测距请求端的类型可以预先划分，可以是基于测距请求端的业务类型划分的，也可以是基于测距请求端的地理位置等划分的。
在一个实施例中，所述至少根据所述目标UE的隐私配置信息，确定是否进行所述协作测距，包括以下之一：
响应于所述协作测距请求指示的测量需求，满足所述隐私配置信息指 示的所述测量要求，接受所述协作测距请求；
响应于所述协作测距请求指示的测量需求，不满足所述隐私配置信息指示的所述测量要求，拒绝所述协作测距请求。
RS根据目标UE的隐私配置信息验证协作测距请求。
如果协作测距请求指示的测量需求满足隐私配置信息中的所有测量要求，则RS接受协作测距请求并继续进行测距任务。否则，RS拒绝协作测距请求。协作测距任务的决定可以由RS作为测距响应消息发送。
RS可以将接受协作测距请求的测距响应消息发送给AMF，由AMF启动协作测距。
这里，测量需求的项目可以根据隐私配置信息中的所有测量要求进行设置。例如，如果测量要求中具有针对辅助UE数量的要求，那么测量需求中可以设置有对辅助UE数量的需求。如果测量需求中需求的辅助UE数量小于或等于测量要求中限定的辅助UE数量，那么可以确定协作测距请求指示的测量需要满足隐私配置信息中的所有测量要求。
协作测距请求也可以不设置测量需求。当协作测距请求不设置测量需求时，可以认为协作测距请求所请求的测距任务基于目标UE隐私配置信息中的测量要求进行。
当RS接受协作测距请求，RS可以指示AMF进行协作测距。RS可以向AMF发送针对协作测距请求的响应，用于指示AMF进行协作测距。
在一个实施例中，所述测量要求，指示至少以下之一：
允许进行所述协作测距时所述目标UE的区域范围；
允许进行所述协作测距的时间；
允许进行所述协作测距的辅助UE的数量；
允许进行所述协作测距的距离精度；
允许进行所述协作测距的方向精度；
进行所述协作测距前是否需要获取所述目标UE的同意指示。
测量要求可以规定进行协作测距时目标UE所处的区域范围。这里，区域范围可以是地理区域，也可以是目标UE所处的小区范围等。当目标UE处于区域范围之内时，RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
允许进行所述协作测距的时间，可以通过允许进行所述协作测距的起始时刻以及持续时长指示，也可以通过允许进行所述协作测距的起始时刻以及结束时刻指示。当目标UE处于允许进行所述协作测距的时间之内时，RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
辅助UE的数量可以影响协作测距得到的最终测量结果的精度，因此，隐私配置信息可以采用限制辅助UE的数量来限制最终测量结果的精度。允许进行所述协作测距的辅助UE的数量可以与协作测距请求中请求的辅助UE的数量进行比较。如果请求的辅助UE的数量小于或等于允许进行所述协作测距的辅助UE的数量，RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
测量要求可以规定进行协作测距的测量结果的精度，测量结果可以包括：协作测距测量到的距离和方向。通过测量要求规定进行协作测距的测量结果的精度来提高目标UE的隐私保护。如果请求的精度小于或等于测量要求可以规定的精度，RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
测量要求还可以规定在进行协作测距之前是否需要获取目标UE的同意指示。目标UE可能存在无法进行协作测距的情况，如负载较大等。因此，核心网等可以在协作测距之前向目标UE发送请求进行协作测距的信息。如果UE返回同意指示，则RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
如此，通过测量要求对协作测距的测量结果对应的区域范围、测量时间、以及精度等进行分类管控，提高对UE位置隐私的细化保护，提高信息安全性。
在一个实施例中，所述方法还包括：
响应于确定进行所述协作测距，获取进行所述协作测距得到的测量结果；

这里，测量结果可以是距离和/或方向，还可以包括：测量结果的精度、测量的时间、进行测量的时间、进行测量时目标UE的区域范围、参与测量的辅助UE的信息，如辅助UE的数量等。
RS可以将测量结果与隐私配置信息指示的测量要求进行比较。RS可以在区域范围、协作测距时间、辅助UE的数量、距离精度和方向精度限制等方面检查测距结果是否符合测量要求，并给予检查结果确定针对测量请求端的反馈信息。例如，当测量结果不满足测量要求时，可以不发送测量结果给测量请求端。
在一个实施例中，所述基于所述测量结果与所述测量要求的比较结果，向所述测距请求端发送所述协作测距的反馈信息，包括至少以下之一：
响应于所述测量结果满足所述测量要求，向所述测距请求端发送所述测量结果；
响应于所述测量结果不满足所述测量要求，向所述测距请求端发送指示所述协作测距错误的测量错误指示信息。
这里，当测量结果满足所述测量要求，那么目标UE的隐私得到保护，可以将测量结果发送给测量请求端。
当测量结果不满足所述测量要求，那么目标UE的隐私未得到保护，可以将测量错误指示信息发送给测量请求端。测量错误指示信息可以指示测量发生错误，也可以指示错误产生的原因，如测量结果不满足所述测量要求，还可以具体指示测量结果不满足所述测量要求的具体项目，例如，测量结果距离精度超出测量要求的距离精度等。
如图5所示，本示例性实施例提供一种信息传输方法，信息传输方法可以被统一数据管理UDM执行，包括：

允许进行所述协作测距的时间；
允许进行所述协作测距的辅助UE的数量；
允许进行所述协作测距的距离精度；
允许进行所述协作测距的方向精度；
进行所述协作测距前是否需要获取所述UE的同意指示。
测量要求可以规定进行协作测距时目标UE所处的区域范围。这里，区域范围可以是地理区域，也可以是目标UE所处的小区范围等。当目标UE处于区域范围之内时，RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
允许进行所述协作测距的时间，可以通过允许进行所述协作测距的起始时刻以及持续时长指示，也可以通过允许进行所述协作测距的起始时刻以及结束时刻指示。当目标UE处于允许进行所述协作测距的时间之内时，RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
辅助UE的数量可以影响协作测距得到的最终测量结果的精度，因此，隐私配置信息可以采用限制辅助UE的数量来限制最终测量结果的精度。允许进行所述协作测距的辅助UE的数量可以与协作测距请求中请求的辅助UE的数量进行比较。如果请求的辅助UE的数量小于或等于允许进行所述协作测距的辅助UE的数量，RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
测量要求可以规定进行协作测距的测量结果的精度，测量结果可以包括：协作测距测量到的距离和方向。通过测量要求规定进行协作测距的测量结果的精度来提高目标UE的隐私保护。如果请求的精度小于或等于测量要求可以规定的精度，RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
测量要求还可以规定在进行协作测距之前是否需要获取目标UE的同意指示。目标UE可能存在无法进行协作测距的情况，如负载较大等。因此， 核心网等可以在协作测距之前向目标UE发送请求进行协作测距的信息。如果UE返回同意指示，则RS可以接收协作测距请求，否则，RS可以拒绝协作测距请求。
如此，通过测量要求对协作测距的测量结果对应的区域范围、测量时间、以及精度等进行分类管控，提高对UE位置隐私的细化保护，提高信息安全性。
在一个实施例中，所述方法还包括，
向核心网发送更新信息，其中，所述更新信息用于更新由统一数据管理UDM存储的所述隐私配置信息。
当UE的负载、业务等发生变化时，UE可以更新自身的隐私配置信息。UE可以向核心网发送更新信息，由UDM等基于更新信息更新所述隐私配置信息。
在一个实施例中，所述更新信息，至少用于更新所述隐私配置信息中的协作测距隐私指示，其中，所述协作测距隐私指示，用于指示是否允许针对所述UE进行所述协作测距。
更新信息可更新协作测距隐私指示，即在允许针对目标UE进行协作测距，和不允许针对目标UE进行协作测距之间进行切换。
在一个实施例中，所述向核心网发送更新信息，包括，
发送携带有所述更新信息的NAS消息。
更新信息可以携带在N1NAS消息中发送给核心网。这里，N1NAS消息是指，通过UE与核心我那个直接的N1接口发送的NAS消息。
在一个实施例中，响应于所述UE为测距请求端，所述方法还包括：
向测距服务器RS发送的请求针对目标UE进行所述协作测距的协作测距请求，其中，所述协作测距请求用于指示进行所述协作测距的测量需求。
测距请求端需要对目标UE进行测距时，可以向RS发送协作测距请求。 协作测距请求可以指示协作测距的目标UE，以及进行协作测距的测量需求等。
示例性的，测量需求可以包括至少以下之一：
进行所述协作测距时所述目标UE的区域范围；
进行所述协作测距的时间；
进行所述协作测距的辅助UE的数量；
进行所述协作测距的距离精度；
进行所述协作测距的方向精度；
当RS接收到协作测距请求时，可以根据隐私配置信息确定是否针对目标UE进行协作测距。
RS根据目标UE的隐私配置信息验证协作测距请求。
如果协作测距请求指示的测量需求满足隐私配置信息中的所有测量要求，则RS接受协作测距请求并继续进行测距任务。否则，RS拒绝协作测距请求。协作测距任务的决定可以由RS作为测距响应消息发送。
RS可以将接受协作测距请求的测距响应消息发送给AMF，由AMF启动协作测距。
这里，测量需求的项目可以根据隐私配置信息中的所有测量要求进行设置。例如，如果测量要求中具有针对辅助UE数量的要求，那么测量需求中可以设置有对辅助UE数量的需求。如果测量需求中需求的辅助UE数量小于或等于测量要求中限定的辅助UE数量，那么可以确定协作测距请求指示的测量需要满足隐私配置信息中的所有测量要求。
协作测距请求也可以不设置测量需求。当协作测距请求不设置测量需求时，可以认为协作测距请求所请求的测距任务基于目标UE隐私配置信息中的测量要求进行。
当RS接受协作测距请求，RS可以指示AMF进行协作测距。RS可以 向AMF发送针对协作测距请求的响应，用于指示AMF进行协作测距。
以下结合上述任意实施例提供一个具体示例：
隐私配置信息的文件存储在UDM中。对于每个目标UE，隐私配置信息确定测距客户端(即测距请求端)是否可以通过协作测距服务获得关于目标UE的距离和方向信息。隐私配置信息包括协作测距隐私指示、测距地理区域、测距时间、辅助UE的数量、测距距离精度限制、测距方向精度限制等。其中：
a)协作测距隐私指示(CRPI，Cooperative ranging privacy indication)指示目标UE的测距结果是否可以通过测距客户端和辅助UE之间的协作获得。CRPI还定义了目标UE在被测距之前是否需要得到同意。
b)测距地理区域指示目标UE允许测距的区域范围。
c)测距时间表示目标UE允许测距的时间段。
d)辅助UE的数量限制指示可以参与协作测距过程的辅助UE的最大数量。通常辅助UE数量越多，最终测距结果的准确度越高。
e)测距精度限制表示目标UE允许的测距距离的最高精度。
f)测距方向精度限制表示目标UE允许的最高测距方向精度。
如图7所述，利用隐私配置信息进行协作测距的具体步骤包括：
步骤701：测距客户端向测距服务器(RS)发送协作测距请求，请求对目标UE进行测距的协作测距服务。RS可以与目标UE的UDM订阅以获得目标UE的隐私配置信息。协同测距请求可以包括测量需求，如测距地理区域、测距时间段、测距距离精度、测距方向精度等。其中：
测距地理区域表示测距任务的区域；
测距时间段表示测距任务的时间段；
测距精度表示所需的测距距离精度；
测距方向精度表示所需的测距方向精度。
步骤702：RS向目标UE的UDM调用Nudm_SDM_Get服务操作，以获得由GPSI或SUPI标识的目标UE的隐私配置信息。UDM返回目标UE的隐私配置信息和目标UE的SUPI。
步骤703：RS根据目标UE的隐私配置信息验证协作测距请求。如果满足隐私配置信息中的所有要求，则RS接受协作测距请求并继续进行测距任务。否则，RS拒绝协作测距请求。协作测距任务的决定由RS作为测距响应消息发送。
步骤704：RS向AMF发送测距响应。
步骤705：AMF开始进行协作测距过程。
步骤706：测距客户端向RS发送中间测距结果。
步骤707：辅助UE向RS发送中间测距结果。
步骤708：RS通过聚合中间测距结果来计算最终测距结果。
步骤709：RS在测距地理区域、测距时间段、辅助UE的最大数量、测距距离精度限制和测距方向精度限制等方面检查最终测距结果是否符合隐私配置信息。当满足所有限制时，RS将最终的测距结果发送给测距客户端。否则，RS发回错误消息。
步骤710：RS向测距客户端发送最终的测距响应。
如图8所述，目标UE更新隐私配置信息的具体步骤包括：
步骤801：UE通过N1NAS消息中的隐私配置信息更新请求，将更新后的CRPI(例如从打开切换到关闭)发送到AMF。
步骤802：AMF向UDM调用Nudm_ParameterProvision_Update服务操作。UDM通过相应地调用Nudr_DM_Update(SUPI，订阅数据)服务操作来更新UDR中UE的隐私配置信息(例如，禁止针对UE的协作测距过程)。
步骤803：AMF通过N1NAS消息中的隐私配置信息更新响应来响应UE。
