Description

一种终端设备位置的验证方法及通信装置
相关申请的交叉引用
本申请要求在2022年03月25日提交中国专利局、申请号为202210304227.X、申请名称为“一种终端设备位置的验证方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种终端设备位置的验证方法及通信装置。
背景技术
接入网设备可以对终端设备所上报的位置信息进行验证。例如，接入网设备可基于终端设备上报的一个或多个时间提前量(time advance，TA)信息验证终端设备上报的位置信息是否准确。
在非陆地网络(non terrestrial networks，NTN)中，接入网设备部署在高空平台或者卫星等非地面设备上。终端设备相对非地面设备的位置不同，对应的TA也有所不同。在NTN网络中，由于终端设备以时隙为单位上报TA，终端设备上报的TA与实际TA相比可能存在误差，例如存在1ms误差。因此基于TA信息验证终端设备的位置的精确度较低。
发明内容
本申请提供一种终端设备位置的验证方法以及通信装置，以提高验证终端设备的位置的精确度。
第一方面，本申请实施例提供一种终端设备位置的验证方法，该方法可由第一通信装置执行，第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片系统。示例性地，所述第一通信装置为接入网设备，或者为设置在接入网设备中的芯片，或者为用于实现接入网设备的功能的其他部件。下面以所述通信设备是第一接入网设备为例进行描述。该方法包括：
第一接入网设备接收终端设备发送的第一位置信息，并向终端设备发送验证信息。之后，第一接入网设备接收终端设备发送的反馈结果，并根据该反馈结果验证第一位置信息。或者，第一接入网设备接收终端设备发送的反馈结果之后，将接收的反馈结果以及第一位置信息发送给核心网设备。其中，验证信息包括如下的至少一项：至少一个参考信号、至少一个验证码，或者至少一个业务数据。相应的，反馈结果包括至少一个参考信号的测量结果，验证码对应的反馈码，或指示信息。该指示信息指示终端设备是否接收到业务数据。
在本申请实施例中，验证信息可用于验证终端设备的位置。例如，第一接入网设备向终端设备发送验证信息，终端设备可向第一接入网设备发送针对验证信息的反馈结果。该反馈结果可指示终端设备是否接收到某个或某些验证信息。如果终端设备没有接收到验证信息，那么终端设备没有位于发送该验证信息的波束的覆盖区域内，从而第一接入网设备可根据反馈结果确定终端设备的位置。通过本申请实施例提供的方法，第一接入网设备通 过向终端设备发送验证信息的方式来验证终端设备上报的位置是否可信。例如，终端设备发送的第一位置信息指示终端设备位于第一位置区域，而第一接入网设备根据反馈结果确定终端设备位于第二位置区域，也可以认为反馈结果指示终端设备位于第二位置区域。如果第一位置区域和第二位置区域无重叠区域，那么第一位置信息不可信。该方法相较于基于TA信息验证终端设备的位置来说，可避免由于终端设备上报TA信息的时延，从而验证位置的精确度更高。另外，第一接入网设备在确定第一位置信息不可信时，可禁止终端设备的某些业务，以减少不合法的业务。
在可能的实现方式中，第一接入网设备根据反馈结果验证第一位置信息，包括：第一接入网设备根据反馈结果确定位置验证结果，该位置验证结果指示第一位置信息指示的位置区域(例如第一位置区域)的可信度。位置的可信度可根据位置的定位精度的需求来确定。例如，如果只要第一位置区域不在第二位置区域范围内，第一位置信息就不可信，那么位置验证结果指示的可信度可为0％。如果允许终端设备实际所在位置区域，例如第二位置区域与第一位置区域存在重叠，那么第一位置区域与第二位置区域重叠较多，可认为第一位置信息可信。例如，第一位置区域与第二位置区域有80％的区域重叠，可认为第一位置信息可信。此时，无需禁止终端设备的业务，以尽量保证合法业务的正常进行。通过位置的可信度来表征位置是否可信，更为合理，减少不合法业务的同时，尽量保证合法业务的正常进行。
在可能的实现方式中，一个参考信号对应一个波束，一个验证码对应一个波束，一个业务数据对应一个波束。即第一接入网设备以波束的形式向终端设备发送验证信息，如果终端设备可获得一个波束对应的参考信号、验证码或业务数据，可认为该波束覆盖该终端设备，从而可确定终端设备所在的位置区域。
在可能的实现方式中，验证信息中的部分验证信息对应的波束的覆盖区域包括第一位置信息指示的位置区域。也可以理解为，第一接入网设备发送的多个波束中，只有部分波束覆盖终端设备，另一部分波束可能并不覆盖终端设备。通过该方案可以防止终端设备虚报反馈结果。例如，编号为4的参考信号对应的波束的覆盖区域并不能覆盖终端设备上报的第一位置区域。若终端设备上报的反馈结果表明测量到了编号为4的参考信号，第一接入网设备则可以认为终端设备虚假上报反馈结果。
在可能的实现方式中，所述波束在不同时间所覆盖的区域不同。也就是，波束的覆盖区域是时变的。针对同一位置区域，需要不同时刻使用的不同的波束，可提高对终端设备位置验证的可靠性，同时，可尽量降低终端设备虚假上报反馈结果的概率。
在可能的实现方式中，第一接入网设备向终端设备发送配置信息，该配置信息指示如下的一项或多项：第一接入网设备发送的参考信号的最大个数、第一接入网设备发送的验证码的最大个数，或者，第一接入网设备发送的业务数据的最大个数。其中，第一接入网设备向终端设备发送的至少一个参考信号的个数小于或等于最大个数。第一接入网设备向终端设备发送的至少一个验证码的个数小于或等于最大个数。第一接入网设备向终端设备发送的至少一个业务数据的个数小于或等于最大个数。该方案中，第一接入网设备实际向终端设备发送的验证信息(波束)的个数小于第一接入网设备为终端设备配置的测量和/或接收验证信息(波束)的个数，从而节约资源开销。例如，第一接入网设备配置终端设备测量8个波束，这8个波束中的3个波束覆盖终端设备，剩余5个波束没有覆盖终端设备。由于5个波束没有覆盖终端设备，即使第一接入网设备发送了这5个波束，终端设备 也测量不到。因此，第一接入网设备可向终端设备发送3个波束，从而节约了资源开销。
在可能的实现方式中，所述配置信息包括如下的一项或多项：测量配置信息、接收配置信息、反馈指示信息，或者上报配置信息。其中，测量配置信息包括用于测量所述至少一个参考信号的配置。接收配置信息包括用于指示第一接入网设备发送参考信号或验证码或业务数据的最大个数的信息。反馈指示信息包括指示终端设备反馈所述反馈结果的配置。上报配置信息包括如下的一项或多项：上报方式、上报门限、上报格式，所述上报方式包括周期上报或非周期上报。上报格式也可以理解为上报的内容，或者上报的内容以何种形式实现。

在可能的实现方式中，所述方法还包括：第一接入网设备向终端设备发送第一指示信息，该第一指示信息指示终端设备的业务被禁止，和/或，第一指示信息指示禁止终端设备的业务的原因。当终端设备的位置不可信时，第一接入网设备可禁止终端设备的业务，即拦截不合法的业务，以尽量保证网络安全或者满足网络监管要求。同时，第一接入网设备也可告知终端设备其业务被禁止。进一步地，第一接入网设备还可以告知终端设备其业务被禁止的原因，从而避免终端设备再次进行不合法业务。
在可能的实现方式中，所述方法还包括：第一接入网设备向核心网设备发送第二指示信息，该第二指示信息包括位置验证结果。第一接入网设备可将位置验证结果告知核心网设备，由核心网设备可根据位置验证结果确定是否禁止终端设备的业务。例如，位置验证结果指示终端设备上报的位置区域不可信，那么核心网设备可禁止终端设备的业务，以减少不合法的业务，尽量保证网络安全。
在可能的实现方式中，第二指示信息还指示如下的一项或多项：请求断开终端设备的连接、请求切换终端设备的核心网设备、发起请求的原因、请求对终端设备的定位。第一接入网设备发现终端设备的位置区域不可信时，可请求核心网设备释放终端设备，例如，请求断开终端设备的连接，或请求切换终端设备的核心网设备，以拦截不合法业务。
在可能的实现方式中，所述方法还包括：第一接入网设备向核心网设备发送第一位置验证信息，该第一位置验证信息包括所述第一位置信息和所述反馈结果。即第一接入网设备将验证信息和反馈结果通知给核心网设备，由核心网设备对第一位置信息进行验证。核心网设备在确定第一位置信息不可信时，也可禁止终端设备的业务，以尽量减少不合法业务。同时，由核心网对第一位置信息进行验证，还可以保护终端设备的隐私。
在可能的实现方式中，所述方法还包括：第一接入网设备接收核心网设备发送的第三指示信息，该第三指示信息包括位置验证结果，该位置验证结果指示第一位置信息指示的位置区域的可信度。核心网设备确定第一位置信息指示的位置区域的可信度之后，可告知第一接入网设备，从而第一接入网设备可释放终端设备，以减少不合法业务。

具体实施方式
为便于本领域技术人员理解本申请实施例提供的技术方案，首先对本申请实施例中的部分用语进行解释说明。
本申请实施例中，网络设备是终端设备通过无线方式接入到移动通信系统中的接入设备，例如包括接入网(access network，AN)设备，例如基站。网络设备也可以是指在空口与终端设备通信的设备。网络设备可以包括LTE系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(evolved Node B)(也简称为eNB或e-NodeB)；网络设备也可以包括5G NR系统中的下一代节点B(next generation node B，gNB)；或者，网络设备也可以包括无线保真(wireless-fidelity，Wi-Fi)系统中的接入节点等；或者网络设备可以为中继站、车载设备以及未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)设备、D2D网络中的设备、机器到机器(machine to machine，M2M)网络中的设备、物联网(internet of things，IoT)网络中的设备或者PLMN网络中的网络设备等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
另外，本申请实施例中的基站可以包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，多个DU可以由一个CU集中控制。CU和DU可以根据其具备的无线网络的协议层功能进行划分，例如分组数据汇聚协议(packet data convergence protocol，PDCP)层及以上协议层的功能设置在CU，PDCP以下的协议层，例如无线链路控制(radio link control，RLC)层和介质访问控制(medium access control，MAC)层等的功能设置在DU。需要说明的是，这种协议层的划分仅仅是一种举例，还可以在其它协议层划分。射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，本申请实施例不作任何限制。另外，在一些实施例中，还可以将CU的控制面(control plan，CP)和用户面(user plan，UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。在该网络架构中，CU产生的信令可以通过DU发送给终端设备，或者UE产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给UE或CU。在该网络架构中，将CU划分为无线接入网(radio access network，RAN)侧的网络设备，此外，也可以将CU划分作为核心网(core network，CN)侧的网络设备，本申请对此不做限制。
所述接入网设备还可以是服务器等。例如，车到一切(vehicle to everything，V2X)技术中的网络设备可以为路侧单元(road side unit，RSU)。以下对接入网设备以为基站为例进行说明。基站可以与终端设备进行通信，也可以通过中继站与终端设备进行通信。终端设备可以与不同接入技术中的多个基站进行通信。
本申请实施例中，核心网设备用于实现移动管理，数据处理，会话管理，策略和计费等功能。不同接入技术的系统中实现核心网功能的设备名称可以不同，本申请实施例并不对此进行限定。以5G系统为例，所述核心网设备包括：接入和移动管理功能(access and mobility management function，AMF)、会话管理功能(session management function，SMF)、策略控制功能(policy control function，PCF)或用户面功能(user plane function，UPF)等。
本申请实施例中，终端设备是一种具有无线收发功能的设备，可以向网络设备发送信号，或接收来自网络设备的信号。终端设备可包括用户设备(user equipment，UE)，有时也称为终端、接入站、UE站、远方站、无线通信设备、或用户装置等等。所述终端设备用于连接人，物，机器等，可广泛用于各种场景，例如包括但不限于以下场景：蜂窝通信、D2D、V2X、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)、物联网(internet of things，IoT)、虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、工业控制(industrial control)、无人驾驶(self driving)、远程医疗(remote medical)、智能电网(smart grid)、智能家具、智能办公、智能穿戴、智能交通、智慧城市(smart city)、无人机、机器人等场景的终端设备。例如，所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、VR终端、AR终端、工业控制中的无线终端、无人驾驶中的无线终端、IoT网络中智能音箱、远程医疗中的无线终端设备、智能电网中的无线终端设备、运输安全中的无线终端设备、智慧城市中的无线终端设备，或智慧家庭中的无线终端设备等等。作为示例而非限定，在本申请的实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。而如上介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。本申请的终端设备还可以是作为一个或多个部件或者单元而内置于车辆的车载模块、车载模组、车载部件、车载芯片或者车载单元，车辆通过内置的所述车载模块、车载模组、车载部件、车载芯片或者车载单元可以实施本申请的方法。
本申请实施例中，用于实现网络设备功能的通信装置可以是网络设备，也可以是能够支持网络设备实现该功能的装置，例如芯片系统，该装置可以被安装在网络设备中。在本申请实施例提供的技术方案中，以用于实现网络设备的功能的装置是网络设备为例，描述本申请实施例提供的技术方案。
本申请实施例中，对于名词的数目，除非特别说明，表示“单数名词或复数名词”，即"一个或多个”。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。例如，A/B，表示：A或B。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，表示：a,b,c,a和b,a和c,b和c,或a和b和c，其中a,b,c可以是单个，也可以是多个。
本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第一位置信息和第二位置信息，可以是同一位置信息，也可以是不同的位置信息，且，这种名称也并不是表 示这两个位置信息指示的位置、优先级或者重要程度等的不同。
如上简单介绍了本申请实施例涉及的技术术语，下面介绍本申请实施例涉及的相关技术方案。
在可能的场景中，终端设备会向接入网设备上报终端设备所在的位置。对于接入网设备而言，可以验证终端设备所上报的位置，从而根据确定结果可执行相应的行为。举例来说，终端设备向接入网设备上报的位置为第一位置区域。但是终端设备实际位于第二位置区域，假设第一业务在第二位置区域不合法，第一业务在第一位置区域合法。如果接入网设备不对终端设备上报的位置进行验证，默认终端设备上报的位置是准确的，那么即使终端设备实际位于第二位置区域，接入网设备也会允许第一业务，会造成网络不安全，网络不合规的问题。
因此，在一些应用场景中，需要验证终端设备的位置。例如，在紧急呼叫路由、公共陆地移动网(public land mobile network，PLMN)的选择，区域业务限制等场景中，需要验证终端设备的位置。有提出基于TA信息验证终端设备的位置。例如，接入网设备可基于终端设备上报的一个或多个TA信息验证终端设备位置。
举例来说，请参见图1，为基于TA信息确定终端设备的位置的示意图。图1包括终端设备和卫星，终端设备相对于卫星的位置不同，终端设备的TA也不同。例如，在T1时刻，终端设备的TA为TA1；在T2时刻，终端设备的TA为TA2；在T3时刻，终端设备的TA为TA3。从图1中可以看出，接入网设备可根据TA1确定圆环1，类似地，接入网设备可根据TA2确定圆环2，根据TA3确定圆环3。终端设备所在位置为圆环1、圆环2和圆环3相交的点。
由于终端设备以时隙为单位上报TA，终端设备上报的TA与实际TA相比存在误差，例如存在1ms误差。因此，接入网设备确定终端设备的位置也存在误差。例如，请参见图2，为终端设备上报的TA与终端设备实际的TA存在误差导致位置估计误差的示意图。图2以卫星在终端设备的正上方为例，如图2所示，假设终端设备实际的TA指示终端设备距离卫星500km。由于终端设备上报TA存在1ms的误差，那么终端设备上报的TA指示终端设备距离卫星为500km+(3×108)m/s×1ms/2＝650km。如图2中的(a)所示，接入网设备基于TA确定终端设备的位置与终端设备实际的位置存在415km的误差。可以理解的是，终端设备相对卫星的位置不同，终端设备上报的TA与终端设备实际的TA之间的误差导致的位置估计误差也有所不同。如图2中的(b)所示，终端设备相对于卫星的正下方偏离45°，终端设备实际的TA指示终端设备距离卫星707km，终端设备上报的TA指示终端设备距离卫星857km，此时，终端设备的位置与终端设备实际的位置存在196km的误差。需要说明的是，图2中终端设备距离卫星的各个距离仅是举例示意。
除了TA上报误差导致位置估计误差之外，卫星的运行轨迹也会额外引入位置估计误差。为方便理解，请参见图3，为卫星运行轨道不在终端设备正上方时基于TA定位终端设备存在位置估计误差的示意图。图3以终端设备上报的TA与终端实际的TA相同，即不存在TA误差为例。图3中，TA1为终端设备在时刻1的实际的TA，TA2为终端设备在时刻2的实际的TA。接入网设备基于TA1确定终端设备位于圆环1上，基于TA2确定终端设备位于圆环2上。由于终端设备与卫星的运行轨迹不重合，圆环1和圆环2的交点有两个，而不是一个。因此，无法确定UE在两个交点的哪个交点位置处。可见，基于TA 验证终端设备的位置的误差较大。
鉴于此，提供本申请实施例的方案。在本申请实施例中，接入网设备可以波束的形式向终端设备发送验证信息，如果终端设备接收和/或测量到验证信息，可认为终端设备位于该验证信息所对应的波束的覆盖范围。因此，终端设备可告知接入网设备所接收或所测量的验证信息，从而接入网设备可根据终端设备的反馈结果，确定终端设备的位置范围。相较于，基于TA信息确定终端设备的位置范围，本申请实施例所提供的方法，可提高终端设备的验证精度，即能够更为准确地验证终端设备的位置。
本申请实施例提供的技术方案可以应用于第四代移动通信技术(the 4th generation，4G)系统，5G系统，NTN系统，车到万物(vehicle to everything，V2X)，长期演进-车联网(LTE-vehicle，LTE-V)，车到车(vehicle to vehicle，V2V)，车联网，机器类通信(Machine Type Communications，MTC)，物联网(internet of things，IoT)，长期演进-机器到机器(LTE-machine to machine，LTE-M)，机器到机器(machine to machine，M2M)，物联网，或者将来的移动通信系统。
作为一种可能的应用场景，NTN系统可以包括卫星系统。按照卫星高度，即卫星轨位高度，可以将卫星系统分为高椭圆轨道(highly elliptical orbiting，HEO)卫星、GEO卫星、中轨(medium earth orbit，MEO)卫星和低轨(low-earth orbit，LEO)卫星。此外，NTN系统还可以包括高空平台(high altitude platform station，HAPS)通信系统等空中网络设备，本申请涉及的空中网络设备不限于以上举例。
作为一种示例，请参见图4，示出了一种NTN网络的架构示意图。该NTN网络包括第一网络设备、第二网络设备、地面基站、地面核心网以及终端。第一网络设备可以是卫星，例如可为HEO卫星、GEO卫星、MEO卫星或LEO卫星，或HAPS等，这里不作限制。第二网络设备可以是网关(或称地面站、地球站、信关站、关口站)(gateway)，可用于连接第一网络设备和基站。一个或多个第一网络设备可以通过一个或多个第二网络设备连接到一个或多个地面基站，在此不做限制。在图4中，第一网络设备的通信模式为透传模式(transparent)，即，第一网络设备作为一个模拟射频中继器，实现无线频率转换和放大，可透传或复制基站与终端之间的信号。例如，终端发送的信号可通过第一网络设备透传，第二网络设备转发，进入地面基站。
本申请实施例对第一网络设备的通信模式不作限制。例如，第一网络设备的通信模式也可以是再生模式(regenerative)。请参见图5，示出了NTN网络的另一种架构示意图。在图5中，第一网络设备的通信模式为再生模式，即第一网络设备可以作为无线通信的基站，实现从地面接收的信号的再生，可以理解并且处理这些信号。例如第一网络设备可以是搭载在人造地球卫星或高空飞行器上的基站，例如基站可以为演进型基站(eNB)或5G基站(gNB)等。第二网络设备可转发第一网络设备(即基站)与核心网之间的信令。
需要说明的是，图5仅示出了一个第一网络设备以及一个第二网络设备，在实际使用中，可根据需要采取多个第一网络设备和/或多个第二网络设备的架构。其中，每个第一网络设备可向一个或多个终端提供服务，每个第二网络设备可对应于一个或多个第一网络设备，每个第一网络设备可对应于一个或多个第二网络设备，本申请实施例不予具体限定。
作为一种示例，请参见图6，示出了NTN网络的另一种架构示意图。图6以包括两个第一网络设备和两个第二网络设备为例。两个第一网络设备的通信模式为再生模式，即两个第一网络设备可以作为无线通信的基站。与图5的区别在于，两个第一网络设备之间存 在卫星之间的链路(inter-satellite link，ISL)。该网络架构下，不同第一网络设备可以相互通信，也可以连接到相同的地面核心网。
作为一种示例，第一网络设备还可以作为基站的DU，与地面基站的CU分离，形成CU DU分布式架构。示例性的，请参见图7，示出了NTN网络的另一种架构示意图。图7与图4的不同之处在于，第一网络设备作为基站的DU，可以理解、处理并再生来自地面的信号，而并不仅是透传或者复制，而地面基站仅作为CU。这种网络架构下，终端设备和第一网络设备之间的服务链路可以传输NR-Uu无线接口信号，第一网络设备和第二网络设备之间的馈电链路传输卫星无线接口(satellite radio interface，SRI)信号，在该SRI信号之上，传输DU与CU之间的F1接口信号。
下面结合附图对本申请实施例提供的终端设备位置的验证方法进行详细介绍。在下文的介绍过程中，该方法可以应用于图4-图7所示的任意通信系统。在本申请实施例中，可由接入网设备对终端设备的位置进行验证，也可以由核心网设备对终端设备的位置进行验证。接入网设备，例如可为图4-图7中的第一网络设备和/或地面基站。需要说明的是，本申请实施例只是以图4-图7所示的通信系统为例，并不限制于这种场景。本文中的参考信号可以是信道状态信息参考信号(channel state information reference signal，CSI-RS)，可以是同步信号和物理广播信道(physical broadcast channel，PBCH)块(synchronization signal and PBCH block，SSB)，或者也可以是其他以波束的形式发送的参考信号，在此并不限定。
请参见图8，为本申请实施例提供的终端设备位置的第一种验证方法的流程示意图。
S801、终端设备向第一接入网设备发送第一位置信息。
终端设备可以向第一接入网设备上报自己所在的位置。例如，终端设备向第一接入网设备发送第一位置信息，该第一位置信息可指示终端设备位于第一位置区域。相应的，第一接入网设备接收终端设备发送的第一位置信息，根据第一位置信息，可确定终端设备位于第一位置区域。例如，第一位置信息可包括第一位置区域的全球定位系统(global positioning system，GPS)坐标。或者，第一位置信息可包括第一位置区域所在的街道地址等。具体第一位置信息包括何种信息，本申请实施例不作限定，只要能够指示第一位置区域即可。
考虑到终端设备上报的第一位置区域与终端设备实际所在的位置区域可能不同。例如，终端设备实际位于第二位置区域，却通知第一接入网设备位于第一位置区域，这种情况下，可将终端设备认为是恶意终端。为避免恶意终端的不合法业务，第一接入网设备可对终端设备上报的第一位置信息进行验证。也就是，验证终端设备上报的位置区域是否可信。关于可信的释义将在下文中具体介绍，此处暂不作说明。
S802、第一接入网设备向终端设备发送验证信息。
验证信息可用于验证第一位置信息是否可信。在本申请实施例中，第一接入网设备可以波束的形式发送验证信息。验证信息与波束具有对应关系。如果终端设备能够接收到该验证信息，可认为，终端设备位于所接收的验证信息对应的波束的覆盖范围内。终端设备将所测量或接收的验证信息对应的波束信息，例如波束ID和/或波束强度等，反馈给第一接入网设备，第一接入网设备根据终端设备反馈的波束信息可验证终端设备上报的位置区域是否可信。
验证信息有多种具体实现形式。示例性的，验证信息可以是参考信号，也可以是验证码，还可以是业务数据等。或者，验证信息也可以包括参考信号、验证码，以及业务数据 中的至少两种。例如，验证信息可包括如下的一项或多项：至少一个参考信号、至少一个验证码，或者至少一个业务数据。其中，一个验证信息可以对应一个波束。例如，一个参考信号对应一个波束，一个验证码对应一个波束，一个业务数据对应一个波束。或者，一个波束可以对应多个验证信息，例如一个波束可以对应多个验证码。或者，一个验证信息也可以对应多个波束，例如一个参考信号对应两个波束。
第一接入网设备接收第一位置信息，可根据第一位置信息确定波束配置信息，该波束配置信息包括第一接入网设备用于发送验证信息的波束配置，例如，发送波束的个数、波束的大小、波束的位置、波束的发射强度、波束的形状等等。需要注意的是，波束配置信息由第一接入网设备使用，不发送给终端设备。
可以理解的是，如果第一接入网设备发送的波束较少，覆盖终端设备的波束也较少，可能无法保证验证终端设备的位置的精度。例如，验证终端设备的位置的精度要求能够验证终端设备位于哪个街道区域，如果第一接入网设备发送一个波束，该波束覆盖的区域为行政区域，根据该波束显然无法将终端设备的位置精确到街道区域。相反，如果第一接入网设备发送多个波束，这多个波束的覆盖区域的交叠区域可能是街道区域，可使得终端设备的位置精确到街道区域。然而第一接入网设备发送较多的波束，相应的，资源开销较大。
为此，在本申请实施例中，第一接入网设备可根据第一位置信息确定波束配置信息，例如确定合适数量的波束，合适方向的波束，以尽量兼顾资源的开销和验证位置的精度。例如，第一接入网设备可确定需要发送的波束是覆盖第一位置区域的多个波束。考虑到第一位置区域可能不可信，第一接入网设备还可以确定发送的波束除了覆盖第一位置区域的波束，还可以包括除覆盖第一位置区域的波束之外的其他波束。
另外，考虑到第一位置信息上报的位置信息可能存在精度误差，也可以认为，第一位置区域存在精度误差。为了尽量节约更多资源或者更为准确地验证终端设备的位置。第一接入网设备还可确定终端设备更为准确的位置，再确定合理的波束配置信息。例如，第一接入网设备可根据第一位置信息和辅助信息确定波束配置信息。该辅助信息可辅助第一接入网设备进一步缩小终端设备所在的位置区域。示例性的，辅助信息可包括终端设备能够测量到的当前服务小区的参考信号的信息，例如，终端设备所在小区的波束信息。例如，终端设备所在的SSB波束ID。其中，辅助信息可以是终端设备之前就上报给第一接入网设备。第一接入网设备可根据辅助信息确定终端设备更为精确的位置，再结合第一位置信息确定波束配置信息。由于第一接入网设备根据辅助信息可确定终端设备更为准确的位置，从而后续所确定的波束配置信息也更为合理。
第一接入网设备根据第一位置信息还可以确定一些配置信息，例如，终端设备测量验证信息的配置、终端设备接收验证信息的配置，终端设备发送针对验证信息的反馈结果的配置等。下面举例介绍配置信息的相关内容，关于第一接入网设备如何根据第一位置信息确定配置信息后续介绍。
配置信息可包括终端设备测量验证信息的配置信息，也称为测量配置信息。例如，该测量配置信息可包括用于测量至少一个参考信号的配置，例如需要测量的参考信号的个数的配置。在一些示例中，配置信息可包括反馈指示信息，该反馈指示信息包括指示终端设备反馈针对验证信息的反馈结果的配置。针对验证信息的反馈结果可指示终端设备所接收的验证信息对应的波束信息。终端设备根据该反馈指示信息可确定是否需要向第一接入网设备发送反馈结果。例如，反馈指示信息指示终端设备发送反馈结果，终端设备接收到该 反馈指示信息，向第一接入网设备发送反馈结果。
配置信息也可包括上报配置信息，该上报配置信息可指示终端设备如何发送反馈结果。例如，该上报配置信息可包括如下的一项或多项，上报方式、上报门限，或上报格式等。上报方式例如为周期上报或非周期上报。终端设备可以根据配置的上报方式发送反馈结果。上报门限，例如包括信号质量门限。例如，终端设备在确定所接收的参考信号的质量大于或等于信号质量门限，终端设备发送的反馈结果包括该参考信号信息和/或对应的波束信息，例如参考信号ID和/或波束ID；相反，如果终端设备所接收的参考信号的质量小于或等于信号质量门限，终端设备发送的反馈结果不包括该参考信号信息和对应的波束信息。上报格式可指示终端设备需要发送的反馈结果的内容或形式。举例来说，验证信息为参考信号，反馈结果可包括终端设备测量到的参考信号的ID、测量到的参考信号对应的帧号或子帧号或符号，或者波束的标识ID等一种或多种。可以理解的是，参考信号的ID与波束的ID具有对应关系。或者，反馈结果也可以包括参考信号的强度。如果验证信息为验证码，反馈结果可包括终端设备接收到的验证码对应的反馈码。验证码对应的反馈码可以是验证码本身，或者反馈码可以是验证码中的一部分。如果验证信息为业务数据，反馈结果可以为指示信息，指示终端设备是否接收到业务数据，例如ACK或NACK指示信息。
配置信息也可包括接收配置信息，该接收配置信息可指示第一接入网设备发送验证信息的最大个数。例如，接收配置信息包括第一接入网设备发送参考信号、验证码或业务数据等的最大个数。终端设备可根据该接收配置信息确定第一接入网设备最多发送多少个验证信息。
第一接入网设备可以根据第一位置信息确定如上的一种或多种配置信息，也可以根据第一位置信息和辅助信息确定如上的一种或多种配置信息。例如，第一接入网设备可确定接收配置信息，即确定第一接入网设备发送验证信息的最大个数。类似的，第一接入网设备也可以根据第一位置信息确定验证信息，或者，根据第一位置信息和辅助信息确定验证信息。例如，确定参考信号的数量、验证码的数量、业务数据的数量等。
第一接入网设备确定配置信息之后，可以向终端设备发送如上的一种或多种配置信息。需要说明的是，如上的一种或多种配置信息也可以是预先定义或者配置的，这种情况下，第一接入网设备也可以不向终端设备发送如上的一种或多种配置信息，在图8中以虚线示意。
可以理解的是，第一接入网设备为基站的DU和CU分离架构时，CU接收终端设备发送的第一位置信息。可由CU根据第一位置信息确定波束配置信息和/或配置信息，也可以由DU确定波束配置信息和/或配置信息。例如，CU可将第一位置信息发送给DU，由DU根据第一位置信息确定波束配置信息和/或配置信息。若由CU确定配置信息，CU确定配置信息之后，可以将配置信息发送给终端设备，也可以将配置信息发送给DU。DU接收配置信息之后，将该配置信息发送给终端设备。若由DU确定配置信息，DU确定配置信息之后，可将配置信息发送给终端设备，也可以将配置信息发送给CU。CU接收到配置信息，将该配置信息发送给终端设备。
第一接入网设备确定验证信息之后，向终端设备发送验证信息。在本申请实施例中，第一接入网设备以波束的形式发送验证信息，也可以理解为，第一接入网设备发送波束。具体来讲，第一接入网设备可以根据确定的配置信息发送验证信息。通常来讲，第一接入网设备发送验证信息的个数与第一接入网设备配置发送验证信息的最大个数相同。即第一 接入网设备配置发送验证信息的最大个数为N，第一接入网设备发送N个验证信息。第一接入网设备配置发送验证信息的最大个数，也可以理解为，第一接入网设备指示终端设备需要测量(验证信息)的个数。
第一接入网设备发送的验证信息中的部分验证信息对应的波束的覆盖区域包括第一位置区域。也就是说，第一接入网设备发送给终端设备的验证信息，终端设备不一定都可以测量或者接收到。举例来说，第一接入网设备发送以8个波束发送8个验证信息，其中，一个波束发送一个验证信息。这8个波束中的3个波束覆盖终端设备，其余的5个波束并不覆盖终端设备。由于第一接入网设备确定哪些波束覆盖第一位置区域，因此通过该方案可以防止终端虚假上报测量结果。例如，编号为4的参考信号对应的波束的覆盖区域并不能覆盖终端设备上报的第一位置区域。若终端设备上报的反馈结果表明测量到了编号为4的参考信号，第一接入网设备则可以认为终端设备虚假上报反馈结果。
考虑到终端设备可能接收不到第一接入网设备发送的部分验证信息。例如，第一接入网设备配置发送验证信息的最大个数为8。以一个验证信息对应一个波束为例，如果这8个验证信息对应的8个波束中有3个波束覆盖终端设备，另外的5个波束没有覆盖终端设备。第一接入网设备认为即使发送了这5个波束，终端设备也接收不到。因此，在本申请实施例中，第一接入网设备实际发送的验证信息的个数可以少于第一接入网设备配置的发送验证信息的最大个数，从而尽量节约资源开销。例如，第一接入网设备配置的发送参考信号的最大个数为N，第一接入网设备实际向终端设备发送的至少一个参考信号的个数为M，M小于N。同理，第一接入网设备发送的验证码的最大个数为P，第一接入网设备实际向终端设备发送的至少一个验证码的个数为Q，Q小于P。第一接入网设备发送的业务数据的最大个数为L，第一接入网设备实际向终端设备发送的至少一个业务数据的个数为K，K小于L。由于第一接入网设备发送更少的波束，所以可降低干扰。同时，还可节省更多的资源，用于其他终端设备的数据传输等，以提高系统性能。
在可能的实现方式中，波束是时变的，也就是，同一个波束在不同时间所覆盖的区域不同。针对同一位置区域，需要不同时刻使用的不同的波束来覆盖。以验证信息是参考信号为例，针对同一位置区域，第一接入网设备在不同时刻可采用不同的波束发送不同的参考信号，即能覆盖该位置区域的参考信号的编号是变化的。例如，在T1时刻，编号为2的参考信号能覆盖终端设备上报的第一位置区域，而编号为4的参考信号则不能。到了T2时刻，编号为4的参考信号能覆盖第一位置区域，而编号为2的参考信号则不能。也就是说，终端设备在某些测量周期不能测量到某个参考信号。例如，在T1时刻，终端设备测量不到编号为4的参考信号。在不同的测量周期，终端设备能测量到的参考信号集合是不同的，例如，在T1时刻，终端设备能测量到编号为2的参考信号，在T2时刻，终端设备能测量到编号为4的参考信号。同理，如果验证信息为验证码(业务数据)，第一接入网设备在不同时刻使用不同的验证码(业务数据)。由于波束是时变的，在不同的测量周期，终端设备能测量到的波束集合是不同的，从而可提高对终端设备位置验证的可靠性。同时，增加了终端设备虚假上报反馈结果的难度，即降低终端设备虚假上报反馈结果的可能性。
可以理解的是，第一接入网设备为基站的DU和CU分离架构时，DU配置波束，且DU以波束的形式向终端设备发送验证信息。其中，DU配置波束所使用的波束配置信息可由CU确定，也可以由DU确定。CU确定该波束配置信息之后，将该波束配置信息发送给DU。
S803、终端设备向第一接入网设备发送反馈结果。
第一接入网设备发送验证信息，如果终端设备接收到验证信息，那么终端设备可向第一接入网设备发送针对该验证信息的反馈结果。反馈结果可指示终端设备接收到对应的验证信息，从而第一接入网设备可确定终端设备接收到哪些波束，进而根据这些波束的覆盖区域验证终端设备的位置。
可以理解的是，反馈结果与验证信息是相对而言的。如果验证信息是参考信号，反馈结果为参考信号的测量结果，例如参考信号的强度、参考信号的ID，或者参考信号对应的波束ID等。如果验证信息是验证码，反馈结果可为验证码对应的反馈码。该反馈码与验证码具有关联关系。示例性的，反馈码可以是验证码，或者，该反馈码也可以是验证码的一部分，例如，反馈码可以是验证码中的前几位，或者，反馈码可以是验证码中的后几位。或者，反馈码也可以是与验证码具有对应关系的码字。例如，反馈码可以是验证码和预设取值之和，等等。如果验证信息是业务数据，反馈结果可以指示终端设备是否接收到业务数据的指示信息。例如，针对业务信息的确认(acknowledge，ACK)或否定确认(no acknowledge，NACK)。需要说明的是，第一接入网设备接收到终端设备针对业务数据发送的ACK，后续第一接入网设备可继续向终端设备发送业务数据，以尽量保证业务的正常进行。如果第一接入网设备接收到终端设备针对某个波束上的业务数据的NACK，说明终端设备不在该波束覆盖范围内。但是第一接入网设备仍然可以向第一位置区域发送业务数据，以尽量保证业务的正常进行。
可以理解的是，终端设备可根据上报配置信息向第一接入网设备发送反馈结果。相应的，第一接入网设备接收终端设备发送的反馈结果。例如，上报配置信息指示的上报方式为周期上报，那么终端设备周期性地向第一接入网设备发送反馈结果。又例如，上报配置信息指示终端设备上报测量参考信号的帧号。终端设备可向第一接入网设备发送所测量或接收的验证信息对应的帧号。另外，如果第一接入网设备以基站的CU和DU分离架构的形式实现，终端设备可将反馈结果发送给DU或CU。
S804、第一接入网设备根据反馈结果验证第一位置信息。
反馈结果可指示终端设备所接收的验证信息对应的波束，也可以认为，反馈结果可指示终端设备所接收的波束。从而第一接入网设备根据反馈结果指示的波束的覆盖区域可验证终端设备所在的位置区域。例如，反馈结果指示3个波束，那么第一接入网设备可确定终端设备位于这3个波束分别覆盖的区域的重叠区域，例如第二位置区域。即反馈结果可间接指示终端设备位于第二位置区域。
第一接入网设备可比较第一位置区域和第二位置区域，从而确定位置验证结果。该位置验证结果可指示第一位置信息是否可信。第一位置信息是否可信可通过第一位置信息指示的位置区域的可信度来表征，也可以认为，位置验证结果可指示第一位置信息指示的位置区域的可信度。第一接入网设备验证第一位置信息是否可信，也就是，确定第一位置信息指示的位置区域的可信度。需要说明的是，可信度和验证精度具有关联关系。例如，一个地理区域的网络监管要求的位置区域验证精度为街道级别，则用于位置验证的第二位置区域也应达到街道级别。如果终端设备上报的第一位置区域的精度更高，例如精确到了某小区，且该小区在第二位置区域的街道内，可认为第一位置区域以街道级别的验证精度来说是可信。如果终端设备上报的第一位置区域的精度更低，例如是行政区域级别，第二位置区域是街道级别，可认为终端设备上报的位置区域不符合精度要求。这种情况下，第一 接入网设备可以根据精度要求，在第一位置区域中进一步确定终端设备当前所在位置，进而确定终端设备在当前位置内的服务是否合法。或者，当终端设备上报的位置区域不符合精度要求，第一接入网设备可认为终端设备上报的位置区域以街道级别的验证精度来说是不可信的。
如果第一位置区域位于第二位置区域内，可认为第一位置区域可信，相应的，可信度为100％。相反，如果第一位置区域与第二位置区域无重叠区域，可认为第一位置区域不可信，相应的，可信度为0％。如果第一位置区域和第二位置区域有重叠区域，可根据重叠区域在第一位置区域的占比可确定可信度。在一些示例中，位置验证结果可包括第一位置信息指示的位置区域的可信度。在一些示例中，位置验证结果可指示第一位置区域是否可信。例如，位置验证结果为1比特信息，该1比特的取值为“0”，指示第一位置区域可信，相应的，该1比特的取值为“1”，指示第一位置区域不可信。或者，该1比特的取值为“1”，指示第一位置区域可信，相应的，该1比特的取值为“0”，指示第一位置区域不可信。
需要说明的是，上述方法以第一接入网设备确定第二位置区域，再通过对比第一位置区域和第二位置区域验证第一位置区域是否可信为例。在可能的实现方式中，第一接入网设备实现无需确定第二位置区域，例如，可通过机器学习的方法，以第一位置信息、验证信息以及反馈结果为输入，第一信息位置是否可信为输出建立反馈结果和第一位置信息是否可信的对应关系。这种情况下，第一接入网设备无需先确定第二位置区域，可根据反馈结果直接验证第一位置信息是否可信。当然，反馈结果和第一位置信息是否可信的对应关系不限于模型的对应关系，也可以是表格的对应关系，本申请实施例对此不做限定。
可以理解的是，第一接入网设备以基站的DU和CU分离架构的形式实现时，位置验证结果可由CU或DU确定。例如，CU接收反馈结果，可确定位置验证结果，或者，CU可将反馈结果发送给DU，由DU确定位置验证结果。又例如，DU接收反馈结果，可确定位置验证结果，或者，DU可将反馈结果发送给CU，由CU确定位置验证结果。可以理解的是，如果位置验证信息由DU确定，若终端设备上报第一位置信息给CU，则还需CU将终端设备上报的第一位置信息发送给DU。
S805、第一接入网设备向终端设备发送第一指示信息。
如果第一接入网设备确定第一位置区域不可信，那么第一接入网设备可禁止终端设备的业务，以减少不合法业务。这种情况下，第一接入网设备可以禁止终端设备的业务。例如，第一接入网设备释放终端设备。另外，第一接入网设备可通知终端设备，第一接入网设备禁止了终端设备的业务。例如，第一接入网设备向终端设备发送第一指示信息，该第一指示信息指示终端设备的业务被禁止。终端设备接收第一接入网设备发送的第一指示信息，可明确业务被禁止。进一步地，第一指示信息还可指示禁止终端设备的业务的原因，从而终端设备可根据该业务确定后续的行为。例如，如果业务的合法性与位置区域关联，终端设备确定业务由于位置区域受限不被允许，那么后续终端设备可在该业务允许的位置区域进行该业务。
需要说明的是，终端设备的业务被禁止，也可以认为，该终端设备被释放。第一指示信息指示终端设备的业务被禁止，也可以理解为，第一指示信息指示终端设备被释放。同理，第一指示信息指示禁止终端设备的业务的原因，也可以理解为，第一指示信息指示终端设备被释放的原因。
在可能的实现方式中，第一接入网设备可以触发NG接口切换过程，以将终端设备连 接到另一核心网设备，例如，另一AMF。例如当第一接入网设备根据第二位置区域确定终端设备发生了跨国家移动时，第一接入网设备可以触发NG接口切换过程，使得终端设备接入第二位置区域对应的国家对应的AMF。切换过程与现有技术相同，此处不再赘述。
可以理解的是，如果第一位置信息指示的位置区域可信，那么第一接入网设备无需发送第一指示信息。因此，S805是可选的步骤，在图8中以虚线进行示意。
可以理解的是，第一接入网设备以CU和DU分离的架构实现时，若DU确定可信度，DU可以生成对应的第一指示信息，并发送给终端设备。或者，DU将可信度发给CU，由CU生成第一指示信息，CU发送给终端设备。若CU确定可信度，CU可以生成对应的第一知识信息，并发送给终端设备。或者，CU将可信度发给DU，由DU生成第一指示信息，DU发给对应的终端设备。
S806、第一接入网设备向核心网设备发送第二指示信息。
第二指示信息可包括位置验证结果。第一接入网设备确定位置验证结果之后，可将该位置验证结果发送给核心网设备。如果该位置验证结果指示第一位置区域不可信，核心网设备可禁止终端设备的业务，例如核心网设备释放终端设备。可选地，第一接入网设备在确定第一位置区域不可信时，将第二指示信息发送给核心网设备。如果第一位置区域可信，第一接入网设备无需向核心网设备发送第二指示信息。因此，S806是可选的步骤，在图8中以虚线进行示意。
如果第一位置区域不可信，第一接入网设备还可以请求核心网设备释放终端设备。例如，第二指示信息还可包括请求核心网设备释放终端设备的信息。核心网设备根据第二指示信息可确定释放终端设备。第一接入网设备也可以触发NG接口切换过程，请求核心网设备将终端设备切换到另一核心网设备。例如，第二指示信息还可以包括请求切换NG接口的信息。由于第一位置区域不可信，第一接入网设备也可以请求核心网设备对终端设备进行定位，以更新终端设备的位置。例如，第二指示信息还可以包括请求核心网设备对终端设备进行定位的信息。进一步地，第一接入网设备可告知核心网设备，第一接入网设备发起请求的原因。例如，第二指示信息可包括用于指示发起请求的原因的信息。在可能的实现方式中，第二指示信息可包括如上的一种或多种信息。也可以理解为，第二指示信息还可以指示如下的一项或多项：请求断开终端设备的连接，请求切换终端设备的核心网设备，发起请求的原因，或请求对终端设备进行定位。
可以理解的是，第一接入网设备以CU和DU分离的架构实现时，如果CU确定可信度，则CU可以确定第二指示信息，并将第二指示信息发送给核心网设备。如果DU确定可信度，DU可将所确定的可信度发送给CU，CU根据可信度确定第二指示信息，再将第二指示信息发送给核心网设备。
需要说明的是，本申请实施例对S805和S806的执行顺序不作限制。即S805可在S806之前执行，或者，S805在S806之后执行，又或者，S805和S806可同时执行。
本申请实施例中，第一接入网设备利用波束向终端设备发送用于验证终端设备的位置的验证信息，例如，至少一个参考信号，至少一个验证码，或者至少一个业务数据等。从而根据终端设备针对验证信息的反馈结果，即接收到的验证信息对应的波束来验证终端设备上报的位置区域。当第一接入网设备确定终端设备上报的位置区域不可信，可禁止终端设备的业务，减少了不合法业务。也可以认为，本申请实施例可识别恶意上报错误位置的终端设备，进而采取对应措施(例如禁止业务)，以尽量保证网络安全。通过本申请实施 例可提供符合网络监管要求的服务，例如，合法拦截(lawful intercept)，紧急通信(emergency communications)，公共警告(public warning service)等。
图8所示的流程由第一接入网设备验证终端设备上位的位置为例。在可能的实现方式中，可由核心网设备验证终端设备上报的位置是否可信。
请参见图9，为本申请实施例提供的终端设备位置的第二种验证方法，该方法的流程描述如下。
S901a、终端设备向第一接入网设备发送第一位置信息。
S901a的实现与S801的实现相同，具体可参考S801的相关内容的介绍，此处不再赘述。
S901b、第一接入网设备向核心网设备发送第一位置信息。
第一接入网设备接收第一位置信息之后，可将该第一位置信息发送给核心网设备，由核心网设备对第一位置信息进行验证。其中，第一接入网设备可以将第一位置信息透传给核心网设备，也可以解析第一位置信息，对第一位置信息处理以后发送给核心网设备。
可以理解的是，第一接入网设备以CU和DU分离的架构实现时，第一接入网设备可通过CU接收并解析该第一位置信息，然后发送给核心网设备。或者，第一接入网设备也可以通过DU接收第一位置信息，并透传给CU，CU再将第一位置信息透传给核心网设备。
S902、第一接入网设备向终端设备发送验证信息。
S902的实现与S802的实现相同，具体可参考S802的相关内容的介绍，此处不再赘述。
S903、第一接入网设备接收终端设备发送的反馈结果。
S903的实现与S803的实现相同，具体可参考S803的相关内容的介绍，此处不再赘述。
S904、第一接入网设备向核心网设备发送第一位置验证信息。
该第一位置验证信息可用于核心网设备验证第一位置信息。第一位置验证信息可包括终端设备针对验证信息的反馈结果。例如，第一接入网设备接收到终端设备发送的反馈结果之后，可将该反馈结果发送给核心网设备，由核心网设备根据第一位置信息和反馈结果验证第一位置信息。
第一位置验证信息还可以包括辅助核心网设备验证第一位置信息的内容。例如，第一位置验证信息还可以包括第一接入网设备发送给终端设备的配置信息，例如，测量配置信息、接收配置信息、上报配置信息等。如上的配置信息的具体实现可参考前述S802的相关内容，此处不再赘述。可以理解的是，核心网设备并不知道波束覆盖哪些区域，因此无法确定终端设备的位置。在一些示例中，第一位置验证信息还可以包括验证信息对应的波束的覆盖范围信息，该覆盖范围信息可指示第一接入网设备在不同时间的不同波束覆盖的区域范围。第一接入网设备通过覆盖范围信息将波束覆盖的区域告知核心网设备，从而核心网设备可以验证终端设备的位置。在一些实施例中，覆盖范围信息可以指示特定波束在不同时间的覆盖区域。特定波束包括终端设备测量到和/或接收到的验证信息对应的波束。也就是，终端设备没有测量到和/或接收到的波束覆盖范围信息无需发送给核心网设备，尽量减少传输数据量。
在另一些示例中，第一位置验证信息还可以包括验证信息，验证信息的配置信息，验证信息对应的波束配置信息、终端设备的至少一个TA信息、至少一个TA信息对应的卫星位置信息、至少一个TA信息对应的时间信息、至少一个TA信息对应的星历信息，或至少一个TA信息对应的小区信息等。可以理解的是，TA信息可指示终端设备的时间提前 量。本申请实施例对TA信息的具体实现形式不作限制。例如，TA信息可以是TA值，也可以是用于计算TA的终端设备的位置信息等。TA信息对应的卫星位置信息可指示终端设备的时间提前量对应的卫星位置。TA信息对应的时间信息可指示终端设备的时间提前量对应的时间。TA信息对应的星历信息可指示终端设备的时间提前量对应的卫星的星历。TA信息对应的时间信息和TA信息对应的星历信息配合使用可确定不同时间对应的星历。TA信息对应的小区信息包括终端设备的时间提前量对应的小区配置，例如小区参考点，小区半径，小区形状等。
需要说明的是，第一位置验证信息包括的部分信息可以提前发送给核心网设备，例如，第一接入网设备在接收到针对验证信息的反馈结果之前，第一接入网设备可将部分配置信息等发送给核心网设备。当然，第一接入网设备也可以将反馈结果和部分配置信息等一起发送给核心网设备。或者，第一接入网设备也可以将终端设备发送的反馈结果透传给核心网设备，第一接入网设备可在任意时间将第一位置验证信息中除反馈结果之外的信息发送给核心网设备。另外，第一接入网设备可向核心网设备发送第一位置信息和反馈结果，也可以向核心网设备发送第一位置信息。若第一接入网设备向核心网设备发送第一位置信息，第一接入网设备还可以向核心网设备发送对反馈结果处理之后的信息。例如，第一接入网设备接收终端设备发送的反馈结果之后，对该反馈结果进行处理之后，形成反馈结果指示的波束的覆盖范围信息，再发送给核心网设备。对于核心网设备来说，尽管接收的是第一接入网设备对反馈结果处理之后的信息，但是根据该信息可确定反馈结果。
需要说明的是，第一位置验证信息包括的验证信息中，部分验证信息对应的波束的覆盖区域包括第一位置区域。对于核心网设备来说，接收反馈结果之后，可以根据波束的覆盖范围信息确定终端设备是否虚报反馈结果。
当第一接入网设备以CU和DU分离的架构实现时，第一位置验证信息由CU发送给核心网设备。例如，第一接入网设备可通过DU接收反馈结果，并确定第一位置验证信息，将该第一位置验证信息发送给CU，再由CU将第一位置验证信息发送给核心网设备。又例如，第一接入网设备可通过DU接收反馈结果，DU将反馈结果发送给CU，CU根据接收的反馈结果确定第一位置验证信息，再将第一位置验证信息发送给核心网设备。又例如，第一接入网设备通过CU接收反馈结果，并确定第一位置验证信息，再将第一位置验证信息发送给核心网设备。
S905、核心网设备根据反馈结果验证第一位置信息。
核心网设备根据反馈结果验证第一位置信息的具体实现与第一接入网设备根据反馈信息验证第一位置信息的具体实现类似，具体可参考前述S804的相关内容，此处不再赘述。
S906、核心网设备向第一接入网设备发送第三指示信息。
第三指示信息可包括位置验证结果。核心网设备确定位置验证结果之后，可将该位置验证结果发送给第一接入网设备。如果该位置验证结果指示第一位置区域不可信，核心网设备可禁止终端设备的业务，例如核心网设备释放终端设备。可选地，核心网设备在确定第一位置区域不可信时，将第三指示信息发送给第一接入网设备。如果第一位置区域可信，核心网设备无需向第一接入网设备发送第三指示信息。因此，S906是可选的步骤，在图9中以虚线进行示意。
如果第一位置区域不可信，核心网设备还可以请求第一接入网设备释放终端设备。例 如，第三指示信息还可包括请求第一接入网设备释放终端设备的信息。第一接入网设备根据第三指示信息可确定释放终端设备。核心网设备也可以请求第一接入网设备发起NG接口切换过程，以将终端设备连接到其他核心网设备。例如，第三指示信息还可以包括请求第一接入网设备发起切换NG接口的信息。进一步地，核心网设备可告知第一接入网设备，核心网设备发起请求的原因。例如，第三指示信息可包括用于指示发起请求的原因的信息。在可能的实现方式中，第三指示信息可包括如上的一种或多种信息。也可以理解为，第三指示信息还可以指示如下的一项或多项：请求断开终端设备的连接，请求切换终端设备的核心网设备，发起请求的原因。
S907、第一接入网设备向终端设备发送第一指示信息。
S907的具体实现同S805的具体实现，具体可参考前述S805的相关内容，此处不再赘述。
可以理解的是，在图9所示的流程中，第一接入网设备也可以以DU和CU分离架构的形式实现。这种情况下，核心网设备发送第三指示信息，CU可接收该第三指示信息。CU接收第三指示信息，确定向终端设备发送第一指示信息，CU可将第一指示信息发送给DU，由DU将第一指示信息发送给终端设备。或者，CU可将第三指示信息发送给DU，DU确定向终端设备发送第一指示信息，并将第一指示信息发送给终端设备。
本申请实施例中，第一接入网设备利用波束向终端设备发送用于验证终端设备的位置的验证信息，接收到据终端设备针对验证信息的反馈结果。可将终端设备的位置信息和反馈结果发送给核心网设备。从而由核心网设备对终端设备上报的位置进行验证。同样在确定终端设备上报的位置区域不可信时，可禁止终端设备的业务，减少了不合法业务。即可识别恶意上报错误位置的终端设备，进而采取对应措施(例如禁止业务)，以尽量保证网络安全。通过本申请实施例可提供符合网络监管要求的服务，例如，合法拦截(lawful intercept)，紧急通信(emergency communications)，公共警告(public warning service)等。同时，识别恶意上报错误位置的终端设备，采取对应措施保证网络安全。另外，由核心网设备验证终端设备的位置，有助于保住用户隐私。
可以理解的是，由于终端设备的移动性，为保证通信的连续性，需要终端设备从源基站切换到目标基站。在基于TA信息确定终端设备的位置过程中，由于终端设备刚接入第二接入网设备时，需要经过一段时间，第二接入网设备才可以获得终端设备的多个TA信息。也就是说，终端设备刚接入第二接入网设备时，第二接入网设备缺少可供参考的历史TA信息，需要经过较长时间获取终端设备的多个TA信息，验证终端设备的位置的时间较长，降低了位置验证的效率。
为此，本申请实施例提供了终端设备位置的第三种验证方法，该方法适用于终端设备的切换场景，例如，终端设备从一个接入网设备切换到另一个接入网设备。为方便描述，下文以终端设备从第一接入网设备切换到第二接入网设备为例。
请参见图10，为本申请实施例提供的终端设备位置的第三种验证方法的流程示意图。该方法以基于TA信息验证终端设备的位置为例。
S1001、终端设备向第一接入网设备发送TA信息。
终端设备可将TA信息发送给第一接入网设备，相应的，第一接入网设备接收该TA信息。终端设备可向第一接入网设备发送一个或多个TA信息。
需要说明的，终端设备上报的TA信息可以是终端设备到卫星的TA信息和卫星到第 一接入网设备的TA信息的叠加信息。例如，终端设备上报的TA信息包括终端设备到卫星之间的TA值与卫星到基站的TA值之和。卫星到第一接入网设备的TA信息可以是第一接入网设备配置给终端设备的。或者，卫星到第一接入网设备的TA信息可以是终端设备根据第一接入网设备的配置和/或相关协议计算出来的。可以理解的是，终端设备到卫星之间的TA信息可用于验证终端设备的位置。如果终端设备上报的TA信息是上述两种TA信息的叠加信息，第一接入网设备需要从该叠加信息中获取终端设备到卫星之间的TA信息。本申请实施例对第一接入网设备如何从叠加信息中获取终端设备到卫星之间的TA信息不作限制。例如第一接入网设备可以通过内部算法实现从叠加信息中获取终端设备到卫星之间的TA信息。当然，终端设备上报的TA信息可以是终端设备到卫星之间的TA信息，这种情况下，第一接入网设备可使用终端设备到卫星之间的TA信息验证终端设备的位置。若无特殊说明，用于验证终端设备的位置的TA信息指的是终端设备到卫星的TA信息。
S1002、第一接入网设备根据TA信息验证终端设备所在的位置区域。
第一接入网设备根据所接收的一个或多个TA信息可确定终端设备位于哪个位置区域。第一接入网设备基于TA信息确定终端设备的位置的原理可参考前述图1实施例相关的内容，此处不再赘述。可以理解的是，在步骤S1002之前，终端设备已经向第一接入网设备上报了终端设备所在的位置区域。
可选地，第一接入网设备以基站的CU和DU分离架构的形式实现，第一接入网设备可通过CU或DU验证终端设备所在的位置区域。例如，第一接入网设备可通过DU接收终端设备发送的TA信息，验证终端设备所在的位置区域。又例如，第一接入网设备可通过DU接收终端设备发送的TA信息，DU将所接收的TA信息发送给CU，由CU根据所接收的TA信息验证终端设备所在的位置区域。或者，第一接入网设备可通过CU接收终端设备发送的TA信息，CU验证终端设备所在的位置区域。应理解，如果DU验证终端设备所在的位置区域，若终端设备上报位置信息给CU，CU应该把终端设备的位置信息发送给DU。
S1003、第一接入网设备向第二接入网设备发送第二位置验证信息。
第一接入网设备为终端设备的服务基站，第二接入网设备可认为终端设备要切换到的目标基站。第二位置验证信息可用于辅助第二接入网设备验证终端设备所在的位置区域。例如，第二位置验证信息可包括用于确定终端设备位置的TA信息。第二接入网设备可根据所接收的TA信息验证终端设备的位置。由于第一接入网设备提前将终端设备的历史TA信息告知第二接入网设备，这样第二接入网设备无需等待较长时间，即可获得能够验证终端设备的位置的TA信息，因此可降低验证终端设备的时延。从而可及时禁止终端设备切换到第二接入网设备后的不合法业务。
需要说明的，第二位置验证信息所包括的TA信息可以是终端设备到卫星的TA信息，也可以是终端设备到卫星的TA信息和卫星到第一接入网设备的TA信息的叠加信息。如果第二位置验证信息所包括的TA信息是终端设备到卫星的TA信息和卫星到第一接入网设备的TA信息的叠加信息，第一接入网设备还应向第二接入网设备发送能够从叠加信息中获取终端设备到卫星的TA信息的辅助信息。例如，第一接入网设备还向第二接入网设备发送卫星到第一接入网设备的TA信息，从而第二接入网设备可根据卫星到第一接入网设备的TA信息从叠加信息中获取终端设备到卫星的TA信息。在透传模式和再生模式的NTN架构中，卫星到接入网设备的TA信息可以为空，也可以非空，本申请实施例对此不 做限定。
第二位置验证信息还可包括位置验证结果和第二位置信息。其中，第二位置信息可指示第一接入网设备所确定的终端设备所在的位置区域。例如，第二位置信息可以是第一位置信息，也就是，第一接入网设备将终端设备上报的位置信息转发给第二接入网设备。又例如，第二位置信息也可以不同于第一位置信息，例如，第一接入网设备确定终端设备位于第二位置区域，第二位置信息可指示第二位置区域。位置验证结果为第一接入网设备对终端设备发送的第一位置信息的验证结果。该位置验证结果可以由第一接入网设备通过前述图8或图9所示的流程获得。
第二位置验证信息还可包括如下的一项或多项：终端设备的至少一个TA信息、至少一个TA信息对应的卫星位置信息、至少一个TA信息对应的时间信息、至少一个TA信息对应的星历信息、至少一个TA信息对应的小区信息、验证信息、验证信息对应的波束的配置信息、验证信息对应的波束的覆盖范围信息，该覆盖范围信息指示波束在不同时间的覆盖区域、配置信息，或反馈信息。其中，至少一个TA信息对应的小区信息，例如包括小区参考点、小区半径、小区形状等。由于基于TA信息确定的区域可能超出小区的范围，而至少一个TA信息对应的小区信息可将终端设备的位置区域限定基于TA信息确定的区域落在小区内，从而可提高验证终端设备的精度。
在可能的实现方式中，第二位置验证信息承载于第一接入网设备向第二接入网设备发送的切换请求消息中。该切换请求消息用于请求第二接入网设备为切换准备资源。本申请实施例可适用于终端设备切换服务基站的场景，复用第一接入网设备向第二接入网设备发送的切换请求消息承载第二位置验证信息，可尽量节约信令开销。
S1004、终端设备切换到第二接入网设备。
终端设备可切换到第二接入网设备。终端设备切换到第二接入网设备的流程是现有技术，此处不作详细介绍。终端设备切换到第二接入网设备之后，可向第二接入网设备上报终端设备的位置，例如终端设备可向第二接入网设备发送第二位置信息，该第二位置信息可指示终端设备所在的位置区域。终端设备切换到第二接入网设备之后，还可以向第二接入网设备上报终端设备的TA信息，以辅助第二接入网设备验证第二位置信息。例如，第二接入网设备可根据来自第一接入网设备的TA信息以及来自终端设备的TA信息验证第二位置信息。
S1005、第二接入网设备根据第二位置验证信息验证终端设备的位置。
第二接入网设备接收第二位置验证信息，可根据终端设备的历史TA信息，验证第二位置信息。例如，第二接入网设备可根据第二位置验证信息中的终端设备的历史TA信息确定终端设备所在的位置区域，将该位置区域与第二位置信息指示的位置区域进行比较，从而确定终端设备的位置是否可信。或者，第二接入网设备可根据第二位置验证信息中的终端设备的历史TA信息以及终端设备发送的TA信息确定终端设备所在的位置区域，将该位置区域与第二位置信息指示的位置区域进行比较，从而确定终端设备的位置是否可信。
如果第一接入网设备将位置验证结果和对应的终端设备上报的位置信息发送给第二接入网设备。第二接入网设备可以位置验证结果确定终端设备上报位置信息的诚信记录，进而可确定验证终端设备的位置的频率和精度，从而提高位置验证的效率。例如，若终端设备在第一接入网设备的诚信记录良好，即终端设备向第一接入网设备上报的位置信息可信的概率较高，那么第二接入网设备可以降低终端设备位置验证的频率，或者推迟对该终 端设备进行首次位置验证的时间。
需要说明的，上述第二接入网设备根据第二位置验证信息验证终端设备的具体方法仅是举例。在可能的实现方式中，第二接入网设备也可以利用神经网络等技术手段根据第二位置验证信息来验证终端设备的位置。
需要说明的是，本申请实施例对S1003和S1004的执行顺序不作限制。即S1003可在S1004之前执行，或者，S1003在S1004之后执行，又或者，S1003和S1004可同时执行。
可选地，第一接入网设备以CU和DU分离架构的形式实现，第二接入网设备以CU和DU分离架构的形式实现。这种情况下，第一接入网设备可通过DU接收终端设备发送的TA信息，确定终端设备的位置验证结果之后，将位置验证结果发送给CU。第一接入网设备通过CU将位置验证结果发送给第二接入网设备的CU。或者，第一接入网设备可通过DU接收终端设备发送的TA信息，将终端设备的TA信息发送给CU，CU确定终端设备的位置验证结果之后，将位置验证结果发送给第二接入网设备的CU。或者，第一接入网设备通过CU接收终端设备的TA信息，确定终端设备的位置验证结果之后，将位置验证结果发送给第二接入网设备的CU。
本申请实施例考虑到目标基站和源基站可能不在一个轨道上，从而源基站将终端设备的历史TA信息告知目标基站。由于目标基站确定终端设备的位置的TA信息由源基站提供，无需自己从终端设备获取，减少了获取终端设备的TA信息的时间，从而提高验证终端设备的位置的效率。另外，目标基站结合终端设备的历史TA信息确定终端设备的位置更为准确，即可提高终端设备的定位精度。
需要说明的是，本申请实施例中，图8所示的流程、图9所示的流程和图10所示的流程可以单独执行，也可以结合。例如，图8所示的流程和图9所示的流程可以相互结合，图8所示的流程和图10所示的流程也可以相互结合。图9所示的流程和图10所述的流程可以相互结合，或者，图8所示的流程、图9所示的流程和图10所示的流程也可以相互结合。
所述本申请提供的实施例中，分别从终端设备、接入网设备，或者核心网设备之间交互的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，终端设备、接入网设备和核心网设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
