Description

未授权无人机的检测方法、装置和系统
本申请要求于2019年04月29日提交中国专利局、申请号为201910353747.8、申请名称为“未授权无人机的检测方法、装置和系统”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
本申请涉及通信技术领域，尤其涉及一种未授权无人机的检测方法、装置和系统。
背景技术
随着电子技术和通信技术的迅速发展，无人机(unmanned aerial vehicle，UAV)相关技术也更加成熟。通过在无人机上设置具有通信能力的芯片，使得无人机作为一种用户设备(user equipment，UE)在空中执行相应的飞行任务。
现有技术中，若该无人机为未接入第三代合作伙伴计划(3rd generation partnership project，3GPP)网络的无人机，则无人机控制器通过网络将该无人机的飞行数据发送到云端，使得监管部门可以根据云端的飞行数据检测该无人机是否违规；或者，监管部门可以通过无人机侦测反制设备检测该无人机是否违规，从而对该无人机进行检测。通常情况下，接入3GPP网络的用户设备请求使用无人机系统通信能力，需要通过无人机系统流量管理(unmanned aerial system traffic management，UTM)网元的鉴权和授权。目前，对于接入3GPP网络但未得到授权的无人机，没有合适的识别或检测方法。其中，未授权的无人机可以理解为满足下述条件的用户设备：不具备无人机系统(unmanned aerial system，UAS)通信能力的用户设备，其移动属性符合无人机的移动属性，或者，具备无人机系统通信能力的用户设备，且在注册时指示不使用该无人机系统通信能力，但其移动属性符合无人机的移动属性，或者，具备无人机系统通信能力的用户设备，且在注册时指示使用该无人机系统通信能力，其移动属性符合无人机的移动属性，但其移动属性信息与其签约信息允许的移动属性信息不相符合。其中，无人机系统通信能力，指接入3GPP系统的用户设备，向3GPP系统请求且得到允许或根据签约数据允许其用于无人机系统通信的能力，一般情况下，该用户设备在使用该无人机系统通信能力时需要满足特定的条件，即特定的移动属性信息。移动属性信息包括特定的时间范围，空间范围，以及运动速度等限制用户设备移动的属性信息。这里的无人机系统包括无人机和无人机控制器。
未授权的无人机对于个人和社会都具有较大的负向影响，可能会造成不可估计的生命财产损失。因此，如何检测已接入3GPP网络但未授权的无人机，是本领域技术人员亟待解决的技术问题。

具体实施方式
本申请实施例可以应用于第五代(the fifth generation，5G)移动通信系统，还可以应用于其他通信系统，例如或未来可能出现的其他移动通信系统。
以下对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。需要说明的是，当本申请实施例的方案应用于5G或未来可能出现的其它移动通信系统时，网络设备和终端的名称可能发生变化，但这并不影响本申请实施例方案的实施。
图1为本申请实施例提供的一种应用场景示意图，示例的，请参见图1所示，本申请实施例可应用于无人机系统(unmanned aerial system，UAS)中，涉及的通信系统可以包括至少一个用户设备、网络设备及接入和移动管理网元(access and mobility management function，AMF)，当然，该通信系统也可以包括统一数据管理网元(Unified Data Management，UDM)和无人机流量管理网元(unmanned aerial vehicle traffic management，UTM)。为了实现对已接入3GPP网络但未授权的无人机的检测，本申请实施例提供了一种未授权无人机的检测方法，AMF向网络设备发送跟踪指示消息；其中，跟踪指示消息用于指示当网络设备覆盖区域内用户设备的属性信息满足预设条件时，上报用户设备的属性信息；其中，属性信息包括位置信息和/或速度信息，并获取用户设备的属性信息；这样在获取到用户设备的属性信息之后，就可以根据用户设备的属性信息，识别用户设备的身份状态，即识别该用户设备是否为未授权无人机，从而实现了对已接入3GPP网络但未授权的无人机的检测。
可以理解的是，在本申请实施例中，未授权的无人机可以理解为满足下述条件的用户设备：不具备无人机系统UAS通信能力的用户设备，其移动属性符合无人机的移动属性，或者，具备无人机系统通信能力的用户设备，且在注册时指示不使用该无人机系统通信能力，但其移动属性符合无人机的移动属性，或者，具备无人机系统通信能力的用户设备，且在注册时指示使用该无人机系统通信能力，其移动属性符合无人机的移动属性，但其移动属性信息与其签约信息允许的移动属性信息不相符合。
需要说明的是，在本申请实施例中，属性信息包括位置信息和/或速度信息，可以理解为属性信息可以只包括位置信息或速度信息，也可以同时包括位置信息和速度信息，具体可以根据实际需要进行设置，在此，本申请实施例不做具体限制。可以理解的是，位置信息不局限于包括用户设备的水平位置，也可以包括用户设备的所在高度。其中，用户设备的水平位置可以通过追踪区域标识确定，也可以通过其他可替代的方式确定，用户设备的高度信息可以是用户设备的海拔高度，也可以是离地面的高度，或者其他用于确定其垂直方向位置的信息；速度信息可以包括用户设备在水平方向上的速度信息，也可以包括用户设备在垂直方向上的速度。
在本申请的实施例中，用户设备(user equipment，UE)又称为终端或终端设备，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载 设备等。常见的用户设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，其中，可穿戴设备例如包括：智能手表、智能手环、计步器等。本申请中的用户设备也可以是具备3GPP系统通信能力的无人机设备。
本申请实施例中涉及的网络设备，又称为无线接入网(radio access network，RAN)设备，是终端设备通过无线方式接入到该移动通信系统中的接入设备，可以是基站NodeB、演进型基站(evolved NodeB，eNB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的下一代基站(next generation NodeB，gNB)、未来移动通信系统中的基站或WiFi系统中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。
在本申请的实施例中，“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这三种情况，其中A，B可以是单数或者复数。在本申请的文字描述中，字符“/”一般表示前后关联对象是一种“或”的关系。
需要说明的是，本申请实施例中的指示、消息等可以是新的消息类型或新的信息元素，也可以包含在已存在的消息或信息元素中。
下面，将通过详细的实施例对本申请实施例提供的未授权无人机的检测方法进行详细地说明，示例的，请参见图2所示，图2为本申请实施例提供的一种未授权无人机的检测方法的示意图，在图2所示的实施例中，是AMF在确定需要对用户设备进行追踪时执行的技术方案，但是具体追踪条件并不做任何限定，该未授权无人机的检测方法可以包括：
S201、AMF向网络设备发送跟踪指示消息。
其中，跟踪指示消息用于指示当网络设备覆盖区域内用户设备的属性信息满足预设条件时，上报用户设备的属性信息；属性信息可以包括位置信息和/或速度信息。可以理解的是，本申请中上报的用户设备的属性信息不局限于用户设备当前的属性信息，可以扩展到该用户设备近期的属性信息。可选的，跟踪指示消息可以包括预设条件，预设条件可以为无人机检测阈值信息，满足预设条件，可以理解为大于或者等于无人机检测阈值。示例的，当用户设备的属性信息包括位置信息和/或速度信息时，对应的，该无人机检测阈值信息可以包括用户设备距离地面高度(AGL)的临界值和/或速度的临界值。速度的临界值可以包括用户设备的平均移动速度临界值，用户设备的瞬间移动速度临界值，关于速度临界值，可能包含水平和垂直方向。
本申请实施例中跟踪指示消息可能指示需要检测的网络设备覆盖区域内用户设备的范围，可以是网络设备覆盖区域内的所有用户设备，也可以是覆盖范围内不具有无人机系统通信能力或具有无人机系统通信能力但指示不使用的用户设备，或者可以是覆盖范围内使用无人机系统通信能力的用户设备。
AMF在向网络设备发送跟踪指示消息之前，需要先获取到无人机检测阈值信息。可选的，在本申请实施例中，AMF获取的无人机检测阈值信息可以为运营商预先配置的检测阈值信息，也可以为接收UTM发送的检测阈值信息。示例的，在接收UTM发送的无人机检测阈值信息时，可以直接接收UTM发送的无人机检测阈值信息，也可以通过NEF等网元 间接接收UTM发送的无人机检测阈值信息。其中，UTM提供的无人机检测阈值信息可能是航空监管部门配置的。需要说明的是，当AMF既接收到UTM发送的无人机检测阈值信息，又被运营商配置了无人机检测阈值信息时，AMF可以将这两种无人机检测阈值信息中的较小值确定为无人机目标检测阈值信息，并将该目标检测阈值信息发送给网络设备。
网络设备在接收到AMF发送的跟踪指示消息之后，就可以根据指示消息中包括的无人机检测阈值信息配置其覆盖区域内的用户设备，即执行下述S202：
S202、网络设备根据无人机检测阈值信息配置其覆盖区域内用户设备。
示例的，网络设备在根据无人机检测阈值信息配置其覆盖区域内的用户设备时，若该网络设备已经获取到用户设备的类型，即是否为具有无人机系统通信能力的用户设备，或者，具有无人机系统通信能力的用户设备注册时选择的能力，即具有无人机系统通信能力的用户设备的注册是否用于飞行，则网络设备可能根据跟踪指示消息指示的网络设备覆盖区域内的用户设备范围或本地配置等向其覆盖区域内的部分用户设备配置无人机检测阈值信息。相反的，若该网络设备没有获取到用户设备的类型，则网络设备可能向其覆盖区域内的所有用户设备配置无人机检测阈值信息。可以理解的是，本申请实施例中的无人机系统通信能力指3GPP系统提供的无人机系统的通信能力，包括无人机系统内部的通信能力，即无人机和无人机控制器之间的通信能力或无人机和无人机之间的通信能力，或无人机系统与UTM之间的通信能力等。
对于处于连接态的用户设备，网络设备可根据上述方法配置阈值信息。对于处于空闲态的用户设备，在其从空闲态切换为连接态时，网络设备可先请求其上报属性信息，再根据上述方法及得到的属性信息确定是否配置阈值信息或直接向AMF上报。
需要说明的是，为了使得用户设备可以识别其距离地面的高度，网络设备还可以向其覆盖区域内的用户设备提供当前用户设备所在地的地面的平均海拔高度，以使用户设备可以根据地面的平均海拔高度，确定其距离地面的高度。
网络设备在通过上述S202根据无人机检测阈值信息配置其覆盖区域内用户设备后，用户设备就可以根据其属性信息和配置的无人机检测阈值信息，确定是否向网络设备上报其属性信息。
S203、若用户设备的属性信息满足预设条件，则向网络设备上报用户设备的属性信息。
可以理解的是，本申请实施例中的用户设备的属性信息满足预设条件，可以指用户设备的某一个参数信息满足其对应的无人机检测阈值信息中的一个阈值，也可以指用户设备的多个参数信息均满足其对应的无人机检测阈值信息中的阈值。需要说明的是，本申请中若用户设备的属性信息满足预设条件，则上报的用户设备的属性信息不局限于用户设备当前的属性信息，可以扩展到该用户设备近期的属性信息。
示例地，用户设备上报的属性信息，可以是直接的也可以是间接的。例如，对于用户设备的属性信息中的速度信息，用户设备可能直接上报速度值和方向，也可能是用户设备上报位置信息和相应的时间戳，据此可推断用户设备的速度信息。
可选的，用户设备在向网络设备上报其属性信息时，可以是该用户设备在接入网络设备时其属性信息已经满足预设条件，这样一旦配置了无人机检测阈值信息，就可以向网络设备上报用户设备的属性信息；也可以是该用户设备在接入网络设备时其属性信息未满足预设条件，但在之后的某个时间点满足预设条件，也可以向网络设备上报用户设备的属性 信息；也可以是在用户设备从空闲态切换到连接态时接收到网络设备的请求后，上报用户设备的属性信息。网络设备在接收到用户设备上报的属性信息之后，可以将该用户设备上报的属性信息发送给AMF，即执行下述S204：
S204、网络设备向AMF发送位置报告消息。
其中，位置报告消息可以包括用户设备的标识，及该用户设备的属性信息，当然，也可以包括其它信息，在此，本申请实施例只是以位置报告消息可以包括用户设备的标识，及该用户设备的属性信息为例进行说明，但并不代表本申请实施例仅局限于此。
可选的，网络设备在向AMF发送位置报告消息时，可以在接收到某一个用户设备上报的属性信息时，直接将该用户设备的属性信息携带在位置报告消息中发送给AMF，也可以等待一个预设时间段，并将该预设时间段内接收到的所有用户设备的属性信息以列表的形式携带在位置报告消息中发送给AMF，具体可以根据实际需要进行设置，在此，对于如何发送位置报告消息，本申请实施例不做进一步地限制。
需要说明的是，在本申请实施例中，网络设备在向AMF发送位置报告消息时，可以不局限于用户设备自己上报的属性信息，还可以包括网络设备主动测量的用户设备的属性信息。通过将用户设备自己上报的属性信息和网络设备主动测量的用户设备的属性信息发送给AMF，使得AMF可以获取到较多的用户设备的属性信息，并根据这些属性信息对用户设备的身份状态进行识别，可以进一步提高识别的准确度。
对于某些场景，网络设备主动测量到的用户设备的属性信息可能取代用户设备上报的属性信息。例如，用户设备在达到阈值或收到网络设备的主动上报请求时，不及时或不上报其属性信息，此时网络设备可能在预设计时器超时后，主动测量用户设备的属性信息，并将得到的属性信息上报给AMF，若测量到的属性信息已超过阈值，则可能同时在上报消息中包含用户设备不及时上报的标识，以作为AMF判断未授权无人机的辅助信息；另外，网络设备可能周期性或选择性测量特性时间空间范围的用户设备的属性信息，若用户设备在达到阈值后上报其属性信息，但其上报的属性信息和网络设备主动测量到的属性信息区别大于预设阈值，则将主动测量到的属性信息上报给AMF，可能同时在上报消息中包含用户设备上报信息异常的标识，以作为AMF判断未授权无人机的辅助信息。
S205、AMF根据用户设备的属性信息，识别用户设备的身份状态。
其中，身份状态包括已授权无人机或未授权无人机。
可选的，在本申请实施例中，在根据用户设备的属性信息，识别用户设备的身份状态时，可以通过至少两种可能的实现方式实现：
在一种可能的实现方式中，AMF根据用户设备的属性信息和用户设备的签约数据对用户设备的身份进行识别，得到用户设备的身份状态。示例的，用户设备的签约数据可以包括该用户设备允许飞行的时间，允许飞行的位置(包括允许飞行的高度)，及允许飞行的速度等信息。
可选的，若AMF没有用户设备的签约数据，则需要向统一数据管理网元UDM发送签约数据查询消息，查询消息用于指示UDM设备查询用户设备的签约数据，以查询该用户设备的签约数据，并接收来自UDM的签约数据响应消息，签约数据响应消息中包括用户设备的签约数据，从而获取到用户设备的签约数据。需要说明的是，若AMF接收到的位置报告消息中包括的是以列表形式存在的用户设备的属性信息，则AMF需要向UDM查 询的是存在于列表中，但AMF中没有相应的签约数据的用户设备的签约数据。
在另一种可能的实现方式中，AMF无需根据用户设备的属性信息和用户设备的签约数据对用户设备的身份进行识别，而是通过向网络数据分析网元(network data analytics function，NWDAF)发送分析请求消息，使得NWDAF设备根据用户设备的属性信息识别用户设备的身份状态，并接收来自NWDAF设备的分析响应消息，分析响应消息包括用户设备的身份状态，从而得到用户设备的身份状态。
其中，分析请求消息包括用户设备的属性信息，该属性信息可以为用户设备在不同时间点的属性信息，分析请求消息用于指示NWDAF设备根据用户设备的属性信息识别用户设备的身份状态。示例的，AMF可以向NWDAF发送分析请求消息，以请求的方式指示NWDAF设备根据用户设备的属性信息识别用户设备的身份状态，当然，也可以订阅的方式指示NWDAF设备根据用户设备的属性信息识别用户设备的身份状态。
由此可见，本申请实施例提供的未授权无人机的检测方法，AMF向网络设备发送跟踪指示消息；其中，跟踪指示消息用于指示当网络设备覆盖区域内用户设备的属性信息满足预设条件时，上报用户设备的属性信息；并获取用户设备的属性信息；这样在获取到用户设备的属性信息之后，就可以根据用户设备的属性信息，识别用户设备的身份状态，即识别该用户设备是否为未授权无人机，从而实现了对已接入3GPP网络但未授权的无人机的检测。
可选的，S205AMF根据用户设备的属性信息，识别用户设备的身份状态后，若用户设备的身份状态为未授权无人机，该未授权无人机的检测方法还可以包括：
S206、AMF向无人机流量管理网元UTM设备发送未授权无人机上报消息。
其中，未授权无人机上报消息用于指示用户设备为未授权无人机。
示例的，未授权无人机上报消息中可以包含用户设备的标识，近期的属性信息等。可选的，未授权无人机上报消息还可以包含未授权无人机的类型，即不具有无人机系统通信能力的用户设备，具有无人机系统通信能力但注册不用于无人机系统通信的用户设备，或具有无人机系统通信能力且注册用于无人机系统通信但其移动属性不符合签约数据允许的移动属性的用户设备。若AMF接收到的位置报告消息中包括的是以列表形式存在的用户设备的属性信息，则AMF可以一次性将未授权的用户设备列表携带在未授权无人机上报消息中发送给UTM，当然，也可以分次将未授权的用户设备列表携带在未授权无人机上报消息中发送给UTM。
S207、AMF向网络设备发送限制指示消息。
其中，限制指示信息用于指示网络设备限制用户设备的可使用网络资源。
AMF在识别出用户设备为未授权无人机时，可以向网络设备发送限制指示消息，以指示网络设备限制用户设备的可使用网络资源。其中，限制用户设备的可使用网络资源可以理解为拒绝该用户设备的数据发送和接收，或只允许用户设备的信令发送和接收，或不允许进行网络切换，或低于某高度或速度时恢复用户设备的数据发送和接收，或只提供较低QoS要求的服务，或其它用于限制用户设备使用网络资源的措施。
需要说明的是，在本申请实施例中，S206和S207之间并无先后顺序，可以先执行S206，再执行S207；也可以先执行S207，再执行S206；当然，也可以同时执行S206和S207，具体可以根据实际需要进行设置，在此，本申请实施例只是以先执行S206，再执行S207 为例进行说明，但并不代表本申请实施例仅局限于此。
基于图2所示的实施例，需要说明的是，在上述图2所示的实施例中，S205AMF根据用户设备的属性信息，识别用户设备的身份状态时，若根据接收到的用户设备的属性信息可以识别出用户设备的身份状态，则可以直接执行上述S206-S207。相反的，若AMF根据接收到的用户设备的属性信息不足以识别出用户设备的身份状态，可能需要在一定的时间段内继续跟踪用户设备的位置，则需要再次获取用户设备的属性信息，以根据再次获取到的用户设备的属性信息识别该用户设备的身份状态。其中，不足以识别出用户设备的身份状态可以包括无法识别出用户设备的身份状态，也可以包括确定用户设备的身份状态为可疑的未授权无人机。示例的，请参见图3所示，图3为本申请实施例提供的另一种未授权无人机的检测方法的示意图，该未授权无人机的检测方法还可以包括：
S301、AMF向网络设备发送跟踪位置指示消息。
示例的，该跟踪位置指示消息可以包括用户设备的标识。此处的用户设备可以为网络设备覆盖区域内，通过上述S201-S205不能确定其身份状态的用户设备。该用户设备的数量可以为一个，也可以为多个。
可以理解的是，在本申请实施例中，若通过上述S201-S205不能识别出某些用户设备的身份状态时，可能需要在一定的时间段内继续跟踪用户设备的位置，则需要再次获取用户设备的属性信息。通常情况下，若AMF确定已收集的用户设备的属性信息不足，或收到NWDAF的响应指示需要继续获取用户设备的属性信息，则AMF需要再次向网络设备发送跟踪位置指示消息，以根据再次获取到的用户设备的属性信息识别该用户设备的身份状态。
示例的，该跟踪位置指示消息除了包括用户设备的标识之外，还可以包括跟踪的频率，上报的频率，采集的时长。上报的频率可以是网络设备多次采集用户设备的属性信息后，一次性发送给AMF，或者，间隔一定时间将多个用户设备的属性信息发送给AMF，具体可以根据实际需要进行设置，在此，本申请实施例不做具体限制。
可以理解的是，若网络设备在获取用户设备的属性信息的过程中，用户设备发生网络切换，则网络设备可以向新的网络设备发送跟踪位置指示消息，或者，AMF再向新的网络设备发送跟踪位置指示消息，从而使得新的网络设备继续获取该用户设备的属性信息。
S302、网络设备指示未识别出身份状态的用户设备上报各自的属性信息。
示例的，网络设备在指示未识别出身份状态的用户设备上报各自的属性信息时，网络设备可以一次性指示用户设备按照指定频率上报各自的属性信息，也可以是网络设备根据指定频率请求用户设备上报各自的属性信息。其中，上报的属性信息中可以包含时间戳。
可选的，未识别出身份状态的用户设备上报各自的属性信息时，可以将其各自的属性信息上报给网络设备，再通过网络设备将该各自的属性信息发送给AMF；或者未识别出身份状态的用户设备可以直接将各自的属性信息上报给AMF，以使AMF获取到未识别出身份状态的用户设备的属性信息。
S303、AMF获取未识别出身份状态的用户设备的属性信息。
其中，属性信息可以包括位置信息和/或速度信息。可以理解的是，本申请中上报的用户设备的属性信息不局限于用户设备当前的属性信息，可以扩展到该用户设备近期的属性信息。
同样需要说明的是，在本申请实施例中，AMF获取的未识别出身份状态的用户设备的属性信息，可以不局限于未识别出身份状态的用户设备自己上报的属性信息，还可以包括网络设备主动测量的未识别出身份状态的用户设备的属性信息。通过获取未识别出身份状态的用户设备自己上报的属性信息和网络设备主动测量的未识别出身份状态的用户设备的属性信息，使得AMF可以获取到较多的用户设备的属性信息，并根据这些属性信息对用户设备的身份状态进行识别，可以进一步提高识别的准确度。
对于某些场景，网络设备主动测量到的未识别出身份状态的用户设备的属性信息可能取代未识别出身份状态的用户设备自己上报的属性信息。例如，未识别出身份状态的用户设备在达到阈值或收到网络设备的主动上报请求时，不及时或不上报其属性信息，此时网络设备可能在预设计时器超时后，主动测量未识别出身份状态的用户设备的属性信息，并将得到的属性信息上报给AMF，若测量到的属性信息已超过阈值，则可能同时在上报消息中包含未识别出身份状态的用户设备不及时上报的标识，以作为AMF判断未授权无人机的辅助信息；另外，网络设备可能周期性或选择性测量特性时间空间范围的未识别出身份状态的用户设备的属性信息，若未识别出身份状态的用户设备在达到阈值后上报其属性信息，但其上报的属性信息和网络设备主动测量到的属性信息区别大于预设阈值，则将主动测量到的属性信息上报给AMF，可能同时在上报消息中包含未识别出身份状态的用户设备上报信息异常的标识，以作为AMF判断未授权无人机的辅助信息。
S304、AMF根据未识别出身份状态的用户设备的属性信息，识别出用户设备的身份状态。
需要说明的是，S304的具体实现过程与上述图2所示的实施例中S205的实现过程类似，具体可以参见上述图2所示的实施例中S205中的相关描述，在此，本申请实施例不再进行赘述。
可以看出，上述S303-S304在识别用户设备的身份状态时，是AMF获取到未识别出身份状态的用户设备的属性信息，从而根据未识别出身份状态的用户设备的属性信息，识别出用户设备的身份状态。当然，在识别用户设备的身份状态时，也可以是NWDAF获取未识别身份状态的用户设备的属性信息，从而根据未识别出身份状态的用户设备的属性信息，识别出用户设备的身份状态。在这种情况下，NWDAF在获取未识别身份状态的用户设备的属性信息时，未识别身份状态的用户设备可以将其各自的属性信息上报给网络设备，再通过网络设备直接将其各自的属性信息上报给NWDAF，或者网络设备通过UPF等网元间接将其各自的属性信息上报给NWDAF；或者，未识别出身份状态的用户设备可以直接将各自的属性信息上报给NWDAF，以使NWDAF获取到未识别出身份状态的用户设备的属性信息。不同的是，NWDAF在根据未识别出身份状态的用户设备的属性信息，识别出用户设备的身份状态之后，需要向AMF发送识别结果，以使AMF根据识别结果获取到用户设备的身份状态。
在通过上述S301-S304进一步识别出用户设备的身份状态之后，若该用户设备为未授权无人机，则可以执行上述S206向无人机流量管理网元UTM设备发送未授权无人机上报消息，以使UTM获取到未授权无人机信息，当然，也可以执行上述S207向网络设备发送限制指示消息，以指示网络设备限制用户设备的可使用网络资源。
由此可见，通过上述图2和图3所示实施例，在检测用户设备是否为未授权无人机时， AMF是通过向网络设备发送跟踪指示消息，以指示当网络设备覆盖区域内用户设备的属性信息满足预设条件时，上报用户设备的属性信息，并在接收到网络设备发送的位置报告消息后，根据位置报告消息中包括的属性信息，识别用户设备是否为未授权无人机；若AMF根据接收到的位置报告消息中包括的属性信息不足以识别出用户设备的身份状态，可能需要在一定的时间段内继续跟踪用户设备的位置，则需要再次获取用户设备的属性信息，以根据再次获取到的用户设备的属性信息识别该用户设备的身份状态，从而实现了对已接入3GPP网络但未授权的无人机的检测。
需要说明的是，在上述图2或图3所示的实施例中，是AMF在确定需要对用户设备进行追踪时，向网络设备发送跟踪指示消息，以执行整个未授权无人机的检测方法，但是并未限定确定的具体情况。示例的，在本申请实施例中，AMF可以在两种可能的情况下，向网络设备发送跟踪指示消息，这两种可能的情况分别为：第一种可能的情况，若AMF接收来自UDM发送的用于指示用户设备的签约数据已发生变更的签约数据变更通知消息；则向网络设备发送跟踪指示消息。第二种可能的情况，若AMF接收来自UTM的检测请求消息，则向用户设备发送跟踪指示消息。下面，将分别对这两种可能的情况的未授权无人机的检测方法进行详细地描述。
在第一种可能的情况下，若AMF接收来自UDM发送的用于指示用户设备的签约数据已发生变更的签约数据变更通知消息；则向网络设备发送跟踪指示消息。示例的，可参见图4所示，图4为本申请实施例提供的又一种未授权无人机的检测方法的示意图，该未授权无人机的检测方法还可以包括：
S401、用户设备执行注册流程，完成注册过程。
其中，用户设备注册时，指示用户设备用于无人机系统通信。
需要说明的是，在本申请实施例中，对于用户设备执行注册流程，以完成整个注册过程的具体实现，具体可参见现有技术中用户设备的注册过程，在此，本申请实施例不在进行赘述。
S402、AMF接收自UDM的签约数据变更通知消息。
其中，所述签约数据变更通知消息用于指示所述用户设备的签约数据已发生变更。示例的，签约数据变更通知消息可以包括签约数据发生变更的用户设备的标识。可以理解的是，在本申请实施例中，签约数据发生变更可能是由于用户设备原本具有无人机系统通信能力，但现在不再具有无人机系统通信能力；或者，在某个特定区域内，用户设备从原本的允许飞行变为不允许飞行。
UTM在检测到某一个或多个用户设备的签约数据发生变更后，向AMF发生签约数据变更通知消息，以通知AMF有用户设备的签约数据发生变更，AMF在接收到该签约数据变更通知消息后，执行下述S403：
S403、AMF根据签约数据变更通知消息，向网络设备发送所述跟踪指示消息。
其中，跟踪指示消息用于指示当网络设备覆盖区域内用户设备的属性信息满足预设条件时，上报用户设备的属性信息；属性信息可以包括位置信息和/或速度信息。当然，该跟踪指示消息还可以指示签约数据已发生变更的用户设备不再具有无人机系统通信能力。
需要说明的是，S403中的跟踪指示消息中指示的覆盖区域内的用户设备不同于上述S201中跟踪指示消息指示的网络设备覆盖区域内用户设备。上述S201中的用户设备是指 网络设备覆盖区域内的用户设备，不具有指向性；而S403中的跟踪指示消息中指示的覆盖区域内的用户设备，是指签约数据发生变更的用户设备，具有指向性。
在向网络设备发送跟踪指示消息之后，就可以执行上述S202-S205，网络设备根据无人机检测阈值信息配置其覆盖区域内用户设备，若用户设备的属性信息满足预设条件，则用户设备向网络设备上报用户设备的属性信息，网络设备向AMF发送位置报告消息，使得AMF根据位置报告消息中包括的用户设备的属性信息，识别用户设备的身份状态，具体可参见上述S202-S205中的相关描述，在此，本申请实施例不再进行赘述。
进一步地，若AMF根据接收到的位置报告消息中包括的属性信息识别出用户设备为未授权无人机，则可以直接执行上述S206-S207；若AMF根据接收到的位置报告消息中包括的属性信息不足以识别出用户设备的身份状态，则执行S301-S304，需要再次获取用户设备的属性信息，以根据再次获取到的用户设备的属性信息识别该用户设备的身份状态。在通过上述S301-S304进一步识别出用户设备的身份状态之后，若该用户设备为未授权无人机，则可以执行上述S206向无人机流量管理网元UTM设备发送未授权无人机上报消息，以使UTM获取到未授权无人机信息，当然，也可以执行上述S207向网络设备发送限制指示消息，以指示网络设备限制用户设备的可使用网络资源。
在第二种可能的情况下，若AMF接收来自UTM的检测请求消息，则向网络设备发送跟踪指示消息。示例的，可参见图5所示，图5为本申请实施例提供的一种未授权无人机的检测方法的示意图，该未授权无人机的检测方法还可以包括：
S501、AMF接收用户设备发送的注册请求消息。
其中，注册请求消息用于指示用户设备用于无人机系统通信。示例的，该注册请求消息可以包括用户设备的标识，也可以包括用户设备的注册区域标识。
S502、AMF接收UTM的检测请求消息。
可选的，检测请求消息可以包括特定区域的信息，和/或用于指示特定区域的阈值信息，当然，也可以包括时间信息。当检测请求消息包括特定区域的信息和时间信息时，用于指示AMF在某个时间段内检测某个区域内的未授权无人机。进一步地，该特定区域的信息可以包括预设条件，预设条件可以包括特定区域对应的高度、平均移动速度、瞬间移动速度，即在该特定区域内，若某一用户设备的属性信息达到预设条件包括的阈值中的某一个或多个，则需要进一步判断该用户设备是否为未授权无人机。示例的，特定区域可以为一些特定场景下的飞行区域，例如，开运动会的校园区域，或者开演唱会的区域等。
可以理解的是，本申请中的特定区域为小区粒度、TA粒度或TA列表粒度等。UTM在向AMF发送检测请求消息时，该特定区域对应的高度、平均移动速度、瞬间移动速度这些信息存放在列表中，以列表的形式携带在检测请求消息中发送给AMF，使得AMF获取到该特定区域对应的高度、平均移动速度、瞬间移动速度这些信息。
S503、向网络设备发送跟踪指示消息。
其中，跟踪指示消息用于指示当网络设备覆盖区域内用户设备的属性信息满足预设条件时，上报用户设备的属性信息；属性信息可以包括位置信息和/或速度信息。
可选的，跟踪指示消息可以包括预设条件，预设条件可以为无人机检测阈值信息。示例的，该无人机检测阈值信息可以包括交集区域对应的高度、平均移动速度及瞬间移动速度。可以理解的是，若用户设备的注册区域同时与多个特定区域存在交集，则选择各交集 区域对应的无人机检测阈值中的最小值作为目标无人机目标检测阈值信息，并将该目标检测阈值信息发送给网络设备。可选的，各区域对应的无人机检测阈值可以为运营商预先配置的检测阈值信息，也可以为接收UTM发送的检测阈值信息，具体可以参见上述图2所示的实施例中S201中的相关描述，在此，本申请实施例不再进行赘述。
可选的，当检测请求消息可以包括特定区域的信息时，若用户设备的注册区域和检测请求消息中包括的特定区域存在交集区域，则AMF向网络设备发送跟踪指示消息。跟踪指示消息中可能包括上报周期，上报周期需要大于或者等于网络设备获取用户设备的属性信息的时间段。
需要说明的是，在本申请实施例中，S503中的跟踪指示消息中指示的覆盖区域内的用户设备不同于上述S201中跟踪指示消息指示的网络设备覆盖区域内用户设备。上述S201中的用户设备是指网络设备覆盖区域内的用户设备，不具有指向性；而本实施例S503中的跟踪指示消息中指示的覆盖区域内的用户设备，是指注册区域与特定区域存在交集的用户设备，具有指向性。
同样的，在向网络设备发送跟踪指示消息之后，就可以执行上述S202-S205，网络设备根据无人机检测阈值信息配置其覆盖区域内用户设备，若用户设备的属性信息满足预设条件，则用户设备向网络设备上报用户设备的属性信息，网络设备向AMF发送位置报告消息，使得AMF根据位置报告消息中包括的用户设备的属性信息，识别用户设备的身份状态，具体可参见上述S202-S205中的相关描述，在此，本申请实施例不再进行赘述。
进一步地，若AMF根据接收到的位置报告消息中包括的属性信息识别出用户设备为未授权无人机，则可以直接执行上述S206-S207；若AMF根据接收到的位置报告消息中包括的属性信息不足以识别出用户设备的身份状态，则执行S301-S304，需要再次获取用户设备的属性信息，以根据再次获取到的用户设备的属性信息识别该用户设备的身份状态。在通过上述S301-S304进一步识别出用户设备的身份状态之后，若该用户设备为未授权无人机，则可以执行上述S206向无人机流量管理网元UTM设备发送未授权无人机上报消息，以使UTM获取到未授权无人机信息，当然，也可以执行上述S207向网络设备发送限制指示消息，以指示网络设备限制用户设备的可使用网络资源。
