图2是根据一示例性实施例示出的一种无人驾驶飞行器UAV能力信息传输方法的流程图，如图2所示，该无人驾驶飞行器UAV能力信息传输方法应用于图1所示的实施环境中，该方法可以包括以下步骤。
在步骤201中，当终端从第二基站切换至第一基站时，第一基站向网络管理设备发送UAV能力信息查询请求，网络管理设备接收该UAV能力信息查询请求。
在本公开实施例中，终端在移动过程中，需要从第二基站切换至第一基站时，第二基站和第一基站之间可以与网络管理设备进行信息交互，以实现路径切换(切换前，核心网到终端的数据从核心网发送至第二基站，并由第二基站转发给终端，切换后，核心网到终端的数据从核心网发送至第一基站，并由第一基站转发给终端)。在该路径切换过程中，第一基站可以向网络管理设备查询切换过来的终端的UAV能力信息。
在步骤202中，网络管理设备根据UAV能力信息查询请求查询终端的UAV能力信息，UAV能力信息指示终端是否具有使用UAV服务的能力。
可选的，网络管理设备可以在本地查询该终端的UAV能力信息，或者，网络管理设备也可以向其它网络设备查询该终端的UAV能力信息。
其中，终端的UAV能力信息指示该终端是否具有使用UAV服务的能力。比如，该终端的UAV能力信息中可以包含UAV指示信息，该UAV指示信息用于指示对应的终端是否为UAV终端，当该UAV指示信息指示对应的终端为UAV终端时，该表示该终端具有使用UAV服务的能力，反之，当该UAV指示信息指示对应的终端不是UAV终端时，该表示该终端不具有使用UAV服务的能力。
可选的，当终端的UAV能力信息指示该终端具有使用UAV服务的能力时，该UAV能力信息还包括：UAV终端类型以及UAV权限信息中的至少一种，该UAV终端类型用于指示该终端所属的UAV类型，该UAV权限信息用于指示该终端是否具有使用UAV服务的权限。
其中，UAV终端类型可以按照终端的UAV功能进行分类，比如，该UAV终端类型可以分为航拍类UAV、农业类UAV、植物保护类UAV、微型自拍类 UAV、快递运输类UAV、灾难救援类UAV、野生动物观察类UAV、传染病监控类UAV、测绘类UAV、新闻报道类UAV、电力巡检类UAV、抢险救灾类UAV、影视拍摄类UAV以及普通UAV等等。
UAV权限信息可以包含用于指示终端是否具有使用UAV服务的权限，以及具有使用哪些UAV服务的权限的信息。
比如，UAV服务可以有多种，终端的UAV权限信息中可以对应每种UAV服务包含一个权限标识，该权限标识用于指示终端是否具有使用对应的UAV服务的权限；或者，在另一种可能的实现方式中，终端的UAV权限信息中可以包含一个服务列表，该服务列表中包含该终端有权限使用的UAV服务的标识，若该服务列表为空，则说明该终端不具有使用任何UAV服务的权限；或者，在另一种可能的实现方式中，终端的UAV权限信息中可以包含一个服务列表，该服务列表中包含该终端没有权限使用的UAV服务的标识，若该服务列表为空，则说明该终端具有使用所有UAV服务的权限。
在步骤203中，网络管理设备向第一基站发送UAV能力信息，第一基站接收该UAV能力信息。
可选的，当UAV能力信息指示该终端具有使用UAV服务的能力时，第一基站向该终端提供UAV服务。
其中，第一基站接收到该终端的UAV能力信息后，可以根据该终端的UAV能力信息决定是否向终端提供UAV服务。
比如，当该终端具有使用UAV服务的能力时，第一基站可以向终端提供UAV服务，当终端不具有使用UAV服务的能力时，第一基站可以不向该终端提供UAV服务。
综上所述，本公开实施例所示的方案，在终端从第二基站切换到第一基站的过程中时，第一基站通过UAV能力信息查询请求向网络管理设备获取该终端的UAV能力信息，实现了在终端从一个基站切换到另一个基站的过程中，使得切换的目标基站能够快速获取终端的UAV能力信息，从而尽可能的缩短目标基站为终端提供UAV服务的反应速度，提高无线通信系统为终端提供UAV服务的系统性能。
在本公开实施例中，第一基站和网络管理设备之间可以基于终端切换过程中已有的信令来传输上述UAV能力信息查询请求以及UAV能力信息。比如， 在终端从第二基站切换到第一基站的过程中，第二基站、第一基站以及MME之间通过信令来交互完成路径切换，当上述网络管理设备是MME时，第一基站和MME之间用来完成路径切换的信令也可以用来传输上述UAV能力信息查询请求以及UAV能力信息。
图3是根据一示例性实施例示出的一种无人驾驶飞行器UAV能力信息传输方法的流程图，如图3所示，以该无人驾驶飞行器UAV能力信息传输方法应用于图1所示的实施环境中，网络管理设备是MME，且第二基站和第一基站之间基于X2接口进行路径切换为例，该方法可以包括以下步骤。
在步骤301中，当终端从第二基站切换至第一基站时，第一基站向MME发送路径切换请求Path Switch Request，MME接收Path Switch Request。其中，该Path Switch Request中包含UAV能力信息查询请求。
在相关技术中，基于X2接口的路径切换时，第一基站和MME之间存在信令交互。比如，请参考图4，其示出了本公开实施例涉及的一种路径切换过程中的信令交互示意图。如图4所示，在相关技术中，基于X2接口进行路径切换时，若终端从第二基站切换到第一基站，则第一基站向MME发送Path Switch Request，MME接收到该Path Switch Request后，向网关发送用户面更新请求，网关接收到该用户面更新请求后完成终端的路径切换，并向MME返回用户面更新确认响应，MME接收到该用户面更新确认响应后，向第一基站发送路径切换请求响应Path Switch Request Acknowledge。第一基站接收到Path Switch Request Acknowledge后，通知第二基站释放资源，第二基站完成释放终端对应的资源。
由图4可见，在相关技术中，在基于X2接口进行路径切换时，第一基站会向MME发送Path Switch Request信令。在本公开实施例中，第一基站可以复用相关技术中的Path Switch Request信令来向MME发送UAV能力信息查询请求，也就是说，第一基站不需要向MME发送新增的信令来传递该UAV能力信息查询请求，从而减少了UAV能力信息传输过程中的信令交互，节约信令资源。
在本公开实施例中，第一基站通过Path Switch Request信令传输该UAV能力信息查询请求时，可以不对Path Switch Request信令进行修改，直接将Path Switch Request信令作为上述UAV能力信息查询请求。
或者，在另一种可能的实现方式中，第一基站通过Path Switch Request信 令传输该UAV能力信息查询请求时，可以对Path Switch Request信令进行修改，比如，第一基站可以在Path Switch Request信令中的某个字段中添加请求标识，该请求标识即为上述UAV能力信息查询请求。
在步骤302中，MME根据UAV能力信息查询请求，向归属签约用户服务器HSS查询终端的UAV能力信息。
其中，UAV能力信息查询请求中可以包含该终端的终端标识，比如，终端的ID、终端对应的电话号码、终端的介质访问控制(Media Access Control，MAC)地址或者终端对应的国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)等等。
MME可以向HSS发送包含终端标识的信息查询请求，HSS根据该终端标识查询该终端的UAV能力信息，并将查询到的UAV能力信息返回给MME。
在本公开实施例中，终端的UAV能力信息可以预先存储在HSS中。比如，当终端首次接入无线通信网络时，终端可以向核心网注册该终端的UAV能力信息，核心网中的HSS对应该终端对应的终端标识保存该终端的UAV能力信息。或者，网络服务商也可以预先注册该终端的UAV能力信息，并将该终端的UAV能力信息对应的终端标识保存在HSS中。
本公开实施例仅以MME向HSS查询终端的UAV能力信息为例进行说明，在实际应用中，该终端的UAV能力信息也可以存储在除了MME以及HSS之外的其它网络设备中，比如，该终端的UAV能力信息也可以存储在PCRF或者策略及计费执行功能单元(Policy and Charging Enforcement Function，PCEF)中，MME接收到UAV能力信息查询请求后，可以向PCRF或者PCEF查询终端的UAV能力信息。
在另一种可能的实现方式中，终端的UAV能力信息也可以直接存储在MME中，MME接收到UAV能力信息查询请求后，可以直接根据UAV能力信息查询请求携带的终端标识，在本地查询该终端的UAV能力信息。
在步骤303中，MME向第一基站发送包含UAV能力信息的路径切换请求响应Path Switch Request Acknowledge，第一基站接收Path Switch Request Acknowledge。
由图4可见，在相关技术中，在基于X2接口进行路径切换时，MME会向第一基站发送Path Switch Request Acknowledge信令。在本公开实施例中，MME可以复用相关技术中的Path Switch Request Acknowledge信令来向第一基 站发送UAV能力信息，也就是说，MME不需要向第一基站发送新增的信令来传递该UAV能力信息，从而减少了UAV能力信息传输过程中的信令交互，节约信令资源。
在本公开实施例中，MME通过Path Switch Request Acknowledge信令传输该UAV能力信息时，可以对相关技术中的Path Switch Request Acknowledge信令进行修改，比如，MME可以在Path Switch Request Acknowledge信令中增加一个或多个字段，通过该一个或多个字段来携带该UAV能力信息，或者，MME也可以在Path Switch Request Acknowledge信令的原有字段(比如预留字段)中添加该UAV能力信息。
比如，在相关技术中，Path Switch Request Acknowledge信令携带有消息类型、终端在MME侧S1接口上的唯一标识(即MME UE S1AP ID)、终端在基站侧S1接口上的唯一标识(即eNB UE S1AP ID)、终端总的最大比特率(UE Aggregate Maximum Bit Rate)以及终端对应的无线承载列表(比如E-RAB To Be Switched in Uplink List)等等。在本公开实施例中，除了上述信息之外，Path Switch Request Acknowledge信令中还携带终端的UAV能力信息，比如，该UAV能力信息可以是UAV授权信息(即UAV Authorized)。该UAV能力信息可以是关于终端使用UAV服务的授权状态的信息。
在步骤304中，第一基站从Path Switch Request Acknowledge中获取该终端的UAV能力信息。
在本公开实施例中，第一基站可以从Path Switch Request Acknowledge中的指定字段中提取该终端的UAV能力信息。
综上所述，本公开实施例所示的方案，在终端从第二基站切换到第一基站的过程中时，第一基站通过UAV能力信息查询请求向MME获取该终端的UAV能力信息，实现了在终端从一个基站切换到另一个基站的过程中，使得切换的目标基站能够快速获取终端的UAV能力信息，从而尽可能的缩短目标基站为终端提供UAV服务的反应速度，提高无线通信系统为终端提供UAV服务的系统性能。
此外，本公开实施例所示的方案，第一基站可以通过相关技术中已有的信令向MME传输UAV能力信息查询请求，MME也可以通过相关技术中已有的信令向第一基站传输切换至第一基站的终端的UAV能力信息，在此过程中不需要增加新的信令，从而减少了UAV能力信息传输过程中的信令交互，节约 信令资源。
在本公开实施例中，第一基站接收到网络管理设备发送的，终端的UAV能力信息后，可以根据该UAV能力信息决定是否为终端提供UAV服务，以及提供何种UAV服务。
图5是根据一示例性实施例示出的一种无人驾驶飞行器UAV能力信息传输方法的流程图，如图4所示，以该无人驾驶飞行器UAV能力信息传输方法应用于图1所示的实施环境中，网络管理设备是MME，且第二基站和第一基站之间基于X2接口进行路径切换为例，该方法可以包括以下步骤。
在步骤501中，当终端从第二基站切换至第一基站时，第一基站向MME发送路径切换请求Path Switch Request，MME接收Path Switch Request。其中，该Path Switch Request中包含UAV能力信息查询请求。
在步骤502中，MME根据UAV能力信息查询请求，向归属签约用户服务器HSS查询终端的UAV能力信息。
在步骤503中，MME向第一基站发送包含UAV能力信息的路径切换请求响应Path Switch Request Acknowledge，第一基站接收Path Switch Request Acknowledge。
在步骤504中，第一基站从Path Switch Request Acknowledge中获取该终端的UAV能力信息。
在步骤505中，当该UAV能力信息指示终端具有使用UAV服务的能力时，第一基站根据UAV终端类型确定该终端对应的UAV服务。
在本公开实施例中，UAV服务可以包括UAV专属的无线资源管理(Radio Resource Management，RRM)服务以及UAV专属的功率控制策略服务中的至少一种。
其中，当UAV能力信息指示终端具有使用UAV服务的能力时，该UAV能力信息还包括UAV终端类型，该UAV终端类型用于指示终端所属的UAV类型。在本公开实施例中，不同的UAV终端类型对应的终端，对应的UAV服务也可以不同。
比如，对于UAV终端类型是灾难救援类UAV、传染病监控类UAV、电力巡检类UAV或者抢险救灾类UAV等功能较为重要的UAV终端，对应的无线资源管理服务中的无线资源管理的优先级较高(比如，此类功能较为重要的 UAV终端可以被优先分配无线资源)，而对于航拍类UAV、农业类UAV、植物保护类UAV、微型自拍类UAV、快递运输类UAV、野生动物观察类UAV、测绘类UAV、新闻报道类UAV、影视拍摄类UAV以及普通UAV等重要性较低的UAV终端，对应的无线资源管理服务中的无线资源管理的优先级较低(比如，此类重要性较低的UAV终端不会被优先分配无线资源)。
或者，对于UAV终端类型是灾难救援类UAV、传染病监控类UAV、电力巡检类UAV或者抢险救灾类UAV等功能较为重要的UAV终端，对应的功率控制策略服务中的发送功率较高(比如，第一基站可以通过较高的发射功率向此类功能较为重要的UAV终端发送信号)，而对于航拍类UAV、农业类UAV、植物保护类UAV、微型自拍类UAV、快递运输类UAV、野生动物观察类UAV、测绘类UAV、新闻报道类UAV、影视拍摄类UAV以及普通UAV等重要性较低的UAV终端，对应的功率控制策略服务中的发送功率较低(比如，第一基站只能通过较低的发射功率向此类功能不重要的UAV终端发送信号，避免对其它终端造成过多的干扰)。
在步骤506中，当UAV权限信息指示终端具有使用UAV服务的权限时，第一基站向终端提供UAV服务。
其中，当UAV能力信息指示终端具有使用UAV服务的能力时，UAV能力信息还包括UAV权限信息，UAV权限信息用于指示终端是否具有使用UAV服务的权限；只有当该UAV权限信息指示终端具有使用该UAV服务的权限时，第一基站才执行向终端提供该UAV服务的步骤。也就是说，即便终端具有使用该UAV服务的能力，如果该终端不具有使用该UAV服务的权限，第一基站也会不为该终端提供UAV服务。
其中，基于该UAV服务，第一基站可以为UAV终端分配专属的无线资源，以免干扰普通终端(比如手机等移动通信中断)或者被普通终端干扰。或者，基于该UAV服务，第一基站可以通过较低的发射功率向UAV终端发送信号，以避免过多的干扰普通终端。
综上所述，本公开实施例所示的方案，在终端从第二基站切换到第一基站的过程中时，第一基站通过UAV能力信息查询请求向MME获取该终端的UAV能力信息，实现了在终端从一个基站切换到另一个基站的过程中，使得切换的目标基站能够快速获取终端的UAV能力信息，从而尽可能的缩短目标基站为终端提供UAV服务的反应速度，提高无线通信系统为终端提供UAV服务的系 统性能。
此外，本公开实施例所示的方案，第一基站可以通过相关技术中已有的信令向MME传输UAV能力信息查询请求，MME也可以通过相关技术中已有的信令向第一基站传输切换至第一基站的终端的UAV能力信息，在此过程中不需要增加新的信令，从而减少了UAV能力信息传输过程中的信令交互，节约信令资源。
另外，本公开实施例所示的方案，当UAV能力信息指示终端具有使用UAV服务的能力时，第一基站根据UAV能力信息中包含的UAV终端类型确定该终端对应的UAV服务，并在UAV能力信息中包含的UAV权限信息指示终端具有使用该UAV服务的权限时，向终端提供该UAV服务，提高了向终端提供UAV服务的灵活性。
通过上述图3和图5所示的实施例，MME可以在终端切换过程中将其UAV的相关能力(即UAV能力信息)告知给切换后的目标基站(即上述第一基站)，使得目标基站能够根据刚刚切换过来的终端的UAV能力来决定是否为其提供UAV的相关服务。也就是说，上述图3和图5所示的方案提出了一种在UAV切换过程中传输UAV能力信息的方法。针对基于X2接口的切换，UAV终端在与目标基站建立无线资源控制(Radio Resource Control，RRC)连接之后，目标基站向MME发送Path Switch Request信令来请求将路径从源基站切换到目标基站，MME在收到目标基站发送的Path Switch Request信令后，查询该终端的UAV能力信息，核实该UE是否被授权使用UAV业务，并将查询结果通过Path Switch Request Acknowledge信令告知目标基站。如果MME指示该终端被授权使用UAV业务，则目标基站可以为该终端提供UAV服务，如果MME指示该终端没有被授权使用UAV业务，则目标基站不会为该终端提供UAV服务。
此外，上述图3和图5所示的实施例均以网络设备为MME，且第一基站复用相关技术中已有的Path Switch Request信令向MME发送UAV能力信息查询请求，MME复用相关技术中已有的Path Switch Request Acknowledge信令向第一基站发送UAV能力信息为例进行说明。而在实际应用中，第一基站可以复用Path Switch Request信令向MME发送UAV能力信息查询请求，而MME不复用Path Switch Request Acknowledge信令，而是通过其它信令向第一基站 发送UAV能力信息；或者，第一基站可以不复用Path Switch Request信令，而是通过其它信令向MME发送UAV能力信息查询请求，而MME复用Path Switch Request Acknowledge信令向第一基站发送UAV能力信息。
此外，上述图3和图5所示的实施例均以第一基站和网络管理设备通过复用相关技术中已有的信令来传输UAV能力信息查询请求以及UAV能力信息为例进行说明。在实际应用中，第一基站和网络管理设备之间也可以通过新增的信令来传输UAV能力信息查询请求以及UAV能力信息。
另外，上述图3和图5所示的实施例均以网络管理设备是MME为例进行说明，在实际应用中，网络管理设备并不限制为MME，也可以是其它网络设备，比如SGW、PGW、PCRF或者HSS等。
下述为本公开装置实施例，可以用于执行本公开方法实施例。对于本公开装置实施例中未披露的细节，请参照本公开方法实施例。
