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实施例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、本公开实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开实施例范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”及“若”可以被解释成为“在……时”或“当……时”或“响应于确定”。
在本公开实施例中涉及的网元或是网络功能,其既可以是独立的硬件设备实现,也可以通过硬件设备中的软件实现,本公开实施例中并不对此做出限定。
侧链(Sidelink,SL)定位是指利用直连通信接口(PC5接口)对UE进行定位,获取绝对位置、相对位置或测距信息。测距是指通过PC5接口确定两个或多个用户设备(User Equipment,UE)之间的距离和/或一个UE相对于另一个UE的方向。侧链定位客户端UE可以发起基于PC5的测距或侧链路定位,但是,其在进行测距或侧链路定位时,缺少对UE的隐私检查,从而导致定位的安全性较低。
其中,在本公开的一个实施例中,UE可以为终端设备。终端设备可以是指向用户提供语音和/或数据连通性的设备。终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,终端设备可以是物联网终端,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)或用户代理(user agent)。或者,终端设备也可以是无人飞行器的设备。或者,终端设备也可以是车载设备,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终端。或者,终端设备也可以是路边设备,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。
定位是一种可检测地理位置和可选的速度(例如移动终端)的功能。目标UE是指在基于测距的服务和侧链定位中使用侧链在一个或多个侧链参考UE的支持下测量其距离、方向和/或位置的UE。
侧链参考UE是指支持为目标UE进行定位的UE,例如,侧链参考UE可以使用侧链,通过发送和/或接收用于定位的参考信号,提供与定位相关的信息等。
侧链参考UE也可以被理解为“锚UE”,锚UE是指当不能支持侧链参考UE和目标UE之间的直接测距或侧链定位时,通过PC5支持侧链参考UE和目标UE之间的测距或侧链定位的UE。锚UE可以通过确定辅助UE和侧链参考UE之间以及辅助UE和目标UE之间的测距或侧链定位的测量/结果,并推导出目标UE和侧链参考UE之间的测距或侧链定位结果。
已定位的UE是指基于通用用户网络接口(User to Network interface Universal,Uu)的定位,其位置已知或能够已知的侧链参考UE。已定位的UE可用于使用侧链定位确定目标UE的位置。
侧链定位服务器UE是指提供位置计算的UE。侧链定位服务器UE用于提供基于侧链定位和测距的服务。侧链定位服务器UE可以根据需要与PC5上的其他UE交互,以计算目标UE的位置。如果目标UE或侧链参考UE支持位置计算,则目标UE或侧链参考UE可以充当侧链定位服务器UE。
侧链定位客户端UE是除侧链参考UE和目标UE之外的第三方UE,侧链定位客户端UE可以代表驻留在其上的应用程序发起测距或侧链定位服务请求。侧链定位客户端UE不必支持测距或侧链定位能力,但侧链定位客户端UE和侧链参考UE/目标UE之间的通信必须通过PC5或通过5GC(5G核心网)建立,用于传输服务请求和结果。
网络辅助操作可以在5GC NF的参与下进行测距或侧链定位操作,用于服务请求处理和结果计算。
相对位置是指相对于其他网络元素或相对于其他UE的UE位置估计。
应用层标识(identity,ID)是指在特定应用的上下文中识别启用测距或侧链启用定位UE的标识符,用于由侧链定位客户端UE在服务请求中识别目标UE和侧链参考UE。
其中,在本公开的一个实施例中,图1为本公开一个实施例所提供的一种UE提供测距服务的举例示意图。如图1所示,无论有无5G覆盖,UE均可支持测距和侧链定位服务,如果许可频段用于测距,则UE完全在操作员控制之下。
可选的,在本公开的一个实施例中,如图1所示,一个测距或侧链定位服务请求可以由一个UE发起,它可以是2个进行测距或侧链定位的UE之一(即UE1和UE2),也可以是一个侧链定位客户端UE。具体的:
当UE1/UE2的上层发起业务请求时,UE1/UE2可以直接触发测距或侧链定位过程到其他UE。
当服务请求由侧链定位客户端UE发起时,侧链定位客户端UE与UE1/UE2之间可以通过PC5或Uu传输服务请求和结果报告。
如果第三个UE在UE1/UE2附近,则可以通过PC5传输服务请求和结果报告,否则,服务请求和结果报告通过Uu传输,即通过网络传输。
仅UE操作可以应用于上述所以情况,仅UE操作是指测距或侧链定位操作,其中服务请求处理和结果计算由UE执行。对于仅UE操作来说,UE之间的通信可以通过PC5进行。
可选的,在本公开的一个实施例中,图2为本公开一个实施例所提供的一种侧链定位客户端UE发起的基于PC5的测距或侧链定位的交互示意图。如图2所示,假设UE1和UE2能够处理测距或侧链定位测量和结果计算,当侧链定位客户端UE靠近UE1/UE2时,该侧链定位客户端UE发起的基于PC5的测距或侧链定位的过程包括以下步骤:
步骤1、向策略控制功能(Policy Control Function,PCF)、数字数据网络管理功能(Digital Data Network Management Function,DDNMF)、UE1和UE2提供服务授权策略或参数;
步骤2、侧链定位客户端UE启动测距或侧链定位设备发现程序以发现UE1或UE2,并且成功发现其中一个(例如UE1或UE2)。在图2中,UE1代表侧链定位客户端UE决定向其发送服务请求的UE。
在一中可能的实现方式中设备发现遵循车用无线通信技术(vehicle to everything,V2X)或邻近服务(Proximity Service,ProSe)的设备发现程序或测距或侧链定位设备发现程序。
其中,当存在以下至少一种情况时,可以跳过步骤2而直接执行步骤:
侧链定位客户端UE和UE1之间存在通信;
侧链定位客户端UE和UE1是同一个UE,即服务请求是从UE1的上层发起的。
步骤3、侧链定位客户端UE向UE1发送测距或侧链定位服务请求,其中,该测距或侧链定位服务请求包括但不限于UE1和UE2的应用层ID、结果内容(距离、角度或两者)、所需的服务质量(Quality of Service,QoS)等。
步骤4、UE1向UE2发起测距或侧链定位程序,以触发测量和结果计算。其中,UE1和UE2的应用层ID用于UE1和UE2在PC5上的通信。同时,测距或侧链定位过程包括测距或侧链定位发现和服务操作,其是否涉及DDNMK取决于根据KI#3开发的解决方案。
步骤5、UE1在测距或侧链定位响应中将UE1和UE2的测距或侧链定位结果发送给侧链定位客户端UE。
其中,当侧链定位客户端UE和UE1是同一个UE,即服务请求是从UE1的上层发起的,则只需要步骤1和步骤4。
易于理解的是,上述过程缺少对UE1和UE2的隐私检查。另外,如果UE1和UE2都不能支持侧链定位服务器功能,则侧链定位服务器UE的参与对于测距或侧链定位来说是必要的,但是上述过程缺少侧链定位服务器UE的参与。
