图1是根据一示例性实施例示出的一种无线通信系统的结构示意图。为便于理解本公开实施例， 首先以图1中示出的无线通信系统为例详细说明适用于本公开实施例的无线通信系统。应当指出的是，本公开实施例中的方案还可以应用于其他无线通信系统中，相应的名称也可以用其他无线通信系统中的对应功能的名称进行替代。
如图1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：若干个用户设备11、若干个网络设备12以及网络管理设备13。
其中，用户设备11可以是指向用户提供语音和/或数据连通性的设备。用户设备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，用户设备11可以是物联网用户设备，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机，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、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备11也可以是可穿戴设备、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备或者VR/AR混合头戴设备。或者，用户设备11也可以是无人飞行器的设备。或者，用户设备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用户设备。或者，用户设备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。
网络设备12，可以为具有接入网设备全部功能或者部分功能的NTN设备，或者也可以为地面上的接入网设备。
NTN中部署在空中的卫星或空中飞行器等设备，可以称为NTN设备。例如，NTN设备可以是：卫星、高空平台(high altitude platform system，HAPS)以及空对地(Air to ground，ATG)设备中任一种。NTN包括透传和非透传(非透传也称为“再生传输”)两种传输类型。在透传NTN中，信号在NTN设备上只进行频率的转换、信号的放大等过程，即NTN设备为终端设备与接入网设备之间的中继设备。在非透传NTN中，NTN设备具有部分或全部接入网设备的功能。
接入网设备是网络侧中一种用于发射或接收信号的实体，如新一代基站(generation Node B，gNodeB)。接入网设备可以是用于与移动设备通信的设备。网络设备可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。网络设备还可协调对空中接口的属性管理。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)。
其中，网络设备12可以是4G系统中采用的演进型接入设备(eNB)。或者，网络设备12也可以是5G系统中采用集中分布式架构的接入设备(gNB)。当网络设备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，本公开实施例对网络设备12的具体实现方式不加以限定。
网络设备12和用户设备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。
在一个实施例中，用户设备11之间还可以建立E2E(End to End，端到端)或D2D(device to device，终端到终端)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。
在一个实施例中，网络设备12可以位于与卫星通信系统融合的通信系统中，且能够为卫星提供连接服务，可以将卫星接入核心网中。例如，所述网络设备12可以是通信系统中具有卫星网关功能的接入网设备，如网关(gateway)设备、地面站设备、非陆地网络网关/卫星网关(Non-terrestrial networks Gateway，NTN-Gateway)等。
在一个实施例中，上述无线通信系统还可以包含网络管理设备13。若干个网络设备12分别与网络管理设备13相连。
在一个实施例中，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，该核心网设备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，该核心网设备也可以是服务网关(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。对于核心网设备13的实现形态，本公开实施例不做限定。

其中，本公开实施例中的AMF、UDM等，均可能由一个实体设备实现，也可能由多个实体设备共同实现。可以理解的是，本公开实施例中的AMF、UDM等，均可能是实体设备内的一个逻辑功能模块，也可能是由多个实体设备组成的一个逻辑功能模块，本公开实施例不做限定。
为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后 与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
非地面网络(NTN)是在地面通信网络的基础上，利用卫星或者空中飞行器向终端设备提供通信服务的通信网络。其中，NTN中部署在空中的卫星或空中飞行器等设备，可以称为NTN设备。例如，NTN设备可以是：卫星、高空平台(high altitude platform system，HAPS)以及空对地(Air to ground，ATG)设备中任一种。NTN包括透传和非透传(非透传也称为“再生传输”)两种传输类型。在透传NTN中，信号在NTN设备上只进行频率的转换、信号的放大等过程，即NTN设备为终端设备与接入网设备之间的中继设备。在非透传NTN中，NTN设备具有部分或全部接入网设备的功能。
以卫星通信为例，当UE使用NTN接入方式接入网络(例如，5G网络)时，由于信息安全、设备管理和/或法规监管方面的需求，需要网络对用户的位置进行验证，以验证用户在当前位置是否允许接入UE选择的公共陆地移动网(Public Land Mobile Network，PLMN)。例如，由于一个卫星小区覆盖范围较大，可能同时涵盖国家A和国家B的区域(典型的在两国交界处卫星小区同时覆盖到两国区域)，且两国网络运营商可能共享所述卫星接入，而国家B的法规要求严禁它国用户以非漫游的方式接入本国运营商网络。此时如果位于边境地区的A国用户通过所述卫星接入选择国家B的网络进行接入，则B国运营商的网络设备(例如AMF)验证用户位置，判断所述用户是否位于B国境内，如果不在B国境内，则禁止所述用户直接接入(非漫游方式)使用B国网络。
相关技术中，UE通过NTN接入网络时，基站设备(例如gNB)将代表UE当前位置的TAI上报给网络设备(例如AMF)，由AMF基于所述TAI进行所述UE的位置验证。所述TAI可基于UE上报的位置信息，该位置信息例如GNSS(Global Navigation Satellite System，全球导航卫星系统)或者A-GNSS(Assisted Global Navigation Satellite System，辅助GNSS，又称为“网络增强卫星定位系统”)，但是根据任何UE产生的位置信息产生代表UE位置的TAI都是不可信的，即存在UE发送欺骗位置的可能。而上述鉴于信息安全、设备管理和/或法规监管等需求，进行UE位置验证的过程，需要确保获取的UE位置可信。
以下对本公开实施例的部分用语进行解释说明，以便于本领域技术人员理解功能。
第一核心网设备：为UE通过NTN接入时所选择的核心网设备。
第二核心网设备：为UE通过TN接入时所选择的核心网设备。
第一核心网设备和第二核心网设备均可以是移动性管理网元，是由运营商网络提供的控制面网元，可以用于负责UE接入运营商网络时的接入控制和移动性管理，其具备例如移动状态管理，分配用户临时身份标识，认证和授权用户等功能。在5G网络中，移动性管理网元可以是AMF，在未来通信如第六代(the 6th generation，6G)中，移动性管理网元仍可以是AMF，或有其它的名称，本公开不做限定。
NTN接入网设备：即NTN网络的接入网设备，可以是具有接入网设备全部功能或者部分功能的NTN设备，或者也可以为与NTN设备连接的接入网设备。
TN接入网设备：即地面网络的接入网设备。
第三核心网设备可以是UDM，用于提供一些控制面数据(例如，可以由多个网络功能(network  function，NF)共享的数据)的管理以及向NF提供请求数据、存储数据、和更新数据的方式。
图2是根据一示例性实施例示出的一种信息处理方法的流程图。所述信息处理方法由第一核心网设备执行，如图2所示，该信息处理方法可以包括：
步骤201a：接收第二核心网设备发送的TN小区标识；
或者，步骤201b：接收TN接入网设备发送的TN小区标识。
其中，所述TN小区标识表示用户设备UE的位置，是所述UE通过所述TN接入使用的小区的标识信息，用于所述第一核心网设备进行所述UE通过NTN接入下的位置验证。
其中，所述UE可以是采用蜂窝移动通信网络技术进行无线通信的手机终端等。所述UE具备支持TN接入和NTN接入的能力，所述UE当前所处的位置区域具有TN接入和NTN接入覆盖。
在一些示例中，所述TN小区标识，用于表示UE的位置，可以是所述UE通过所述TN接入小区的小区全局标识(Cell Global Identifier，CGI)。CGI可用于识别一个小区所覆盖的区域。
在一些示例中，所述TN小区标识，可以是由TN接入网设备在所述UE通过所述TN接入的过程中，发送给所述第二核心网设备，并由所述第二核心网设备发送给所述第一核心网设备的。

其中，所述第一核心网设备的标识可以是所述第二核心网设备从第三核心网设备(例如，UDM)获取的，并由所述第二核心网设备发送给所述TN接入网设备的。
在一些示例中，所述TN小区标识，可以携带于所述TN接入网设备发送给第一核心网设备的注册请求消息中。
其中，第一核心网设备可以从TN接入网设备发送的注册请求消息中读取出所述UE通过所述TN接入使用的TN小区标识。
本公开实施例提供一种信息处理方法，通过第一核心网设备接收第二核心网设备或TN接入网设备发送的TN小区标识，TN小区标识用于所述第一核心网设备进行所述UE通过NTN接入下的位置验证，由于TN小区覆盖范围的有限性，TN小区标识作为UE通过TN接入使用的小区的标识信息，能够准确地表示UE的位置，因此相较于代表UE位置的TAI，TN小区标识的可信度更高，能够提升NTN接入场景下的UE位置验证的可靠性。
在一些实施例中，接收第二核心网设备或者地面网络TN接入网设备发送的TN小区标识，可以包括：
接收所述第二核心网设备或者所述TN接入网设备发送的TN小区标识以及所述TN小区标识相关的时间戳。
其中，所述TN小区标识相关的时间戳可反映出发送给所述第一核心网设备的TN小区标识是否可靠。若所述时间戳记录的时间和当前时间越靠近，表明TN小区标识所表示的UE位置越接近UE当前的真实位置，则第一核心网设备进行UE通过NTN接入下的位置验证的可靠性越高。
在一个实施例中，所述第一核心网设备是所述UE通过所述NTN接入时，NTN接入网设备选择的；所述第二核心网设备是所述UE通过所述TN接入时，TN接入网设备选择的。

其中，所述注册拒绝消息中可包含拒绝所述UE通过所述TN接入网络接入的原因值。
本实施例中，在UE通过NTN接入网络时，为获得可信度高的UE位置信息，第一核心网设备可指示UE通过TN接入，以获取UE通过TN接入使用的TN小区的标识信息(即TN小区标识)。在接收到TN接入网设备发送的TN小区标识后，第一核心网设备会向UE发送拒绝UE通过TN接入网络的注册拒绝消息。
在一个实施例中，所述UE通过非地面网络NTN接入下的位置验证，可以包括：
基于所述TN小区标识对应的UE位置信息，验证所述UE在所述UE的位置下是否允许接入所述UE选择的PLMN；如果不允许，向所述UE发送通过所述NTN接入的去注册消息。
当第一核心网设备验证所述UE在所述UE的位置下不允许接入所述UE选择的PLMN时，会向UE发起去注册流程。例如，第一核心网设备向UE发送去注册请求(de-registration request)消息，其中，去注册消息中可携带至少一个指示信息，所述指示信息可用于向所述UE指示位置验证不通过。例如，所述提示信息可以表征UE在当前位置不允许接入所述PLMN。

为了进一步解释本公开任意实施例，以下提供几个具体实施例。
本公开实施例中的UE具备支持TN接入和NTN接入的能力，且在UE当前所处的位置区域具有TN接入和NTN接入覆盖。
为了能够有效实施对UE通过NTN接入时进行位置验证，本公开借助于UE通过TN接入，由TN接入上报UE的位置信息给位置验证网元(即，上述实施例中的第一核心网设备)。由于UE接入网络的过程中(无论是通过TN接入还是通过NTN接入)，都会上报小区标识(CGI)，所述CGI都会包含位置信息。UE选择的TN小区对应的小区标识包含的位置信息即可代表UE当前所处的位置信息。
如图5所示，TN小区标识为CGI，其结构组成为：MCC(Mobile Country Code，移动国家代码)、MNC(Mobile Network Code，移动网络号码)、LAC(Location Area Code，位置区域码)和CID(Cell Identity，小区识别码)。CGI是位置区识别码(Location Area Identity，LAI)的基础上再加小区识别 码(CID)构成的。
基于所述TN接入上报的UE位置信息，位置验证网元执行NTN接入场景下的用户位置验证。
具体地，本公开实施例提供一种信息处理方法，该方法可以包括步骤：
S1：在UE通过NTN接入网络过程中，第一网元(位置验证网元)向UE返回指示，用于请求UE使用TN接入。
S2：根据来自第一网元的指示，UE通过TN发起接入请求，由TN选择第二网元，并将位置信息(UE在TN网络选择的CGI)上报给第二网元。
S3：第二网元将所述位置信息发送给第一网元。
S4：第一网元根据所述位置信息，执行位置验证，即判断UE在当前位置是否允许通过NTN接入第一网元所在的PLMN。
下面以AMF1为第一核心网设备，AMF2为第二核心网设备为例，结合流程图对本公开实施例提供的信息处理方法进行说明，该方法可以应用于UE通过TN和NTN接入相同的PLMN的场景中。
如图6所示，该信息处理方法可以包括以下步骤：
1.UE通过NTN接入发起接入注册请求，请求消息中包含UE支持TN接入的能力。NTN RAN根据SUCI等信息选择AMF1，并将注册请求发送给AMF1。
2.AMF1处理UE注册请求消息，向UDM发起注册，作为UE注册过程的一部分，AMF1将AMF1标识，UE使用的NTN接入类型发送给UDM保存。
3.AMF1接收UE通过NTN的注册请求，向UE返回注册成功的响应。在所述响应消息中包含指示信息(即，上述实施例中的位置验证指示信息)，所述指示信息指示需要NTN位置验证，请求UE使用TN接入网接入。
4.根据所述指示信息，UE通过TN接入网络发起注册请求消息，注册请求中携带信息用于指示该注册过程用于NTN位置验证。TN RAN根据SUCI等信息选择AMF2，并将UE选择的小区对应的小区信息上报给AMF2。其中，所述小区信息包含了位置信息。
5.根据注册请求中携带的指示信息，AMF2获知此过程为用于NTN位置验证的位置获取过程，AMF2向UDM发起请求，包含所述指示信息，UDM根据所述指示信息，将步骤2保存的AMF1标识信息发送给AMF2。
6.AMF2根据AMF1标识信息，向AMF1发起通知消息，将步骤4获取的UE位置信息，发送给AMF1。
或者，AMF2向TN RAN发送重路由消息，包含AMF1标识信息。TN RAN根据所述AMF1标识信息，向AMF1发送注册请求，请求消息中包含所述UE位置信息。
7.当AMF1获取所述UE位置信息后，对应地，如果是case A(即，所述UE位置信息是由AMF2向AMF1发送的)，可以由AMF2向UE返回注册拒绝消息；如果是case B(即，所述UE位置信息是由TN RAN向AMF1发送的)，可以由AMF1向UE返回UE通过TN接入的注册拒绝消息。
8.AMF1基于所述UE位置信息，执行NTN接入下的位置验证过程，即判断UE在所述位置是 否允许接入AMF1所在的PLMN，如果允许接入，则流程结束。如果不允许接入，则AMF1向UE发起去注册流程，并说明UE在当前位置不允许接入所述PLMN。
