本公开涉及无线通信技术领域，尤其涉及一种无人机飞行信息的传输方法、装置、基站及核心网设备。
无人驾驶飞机(Unmanned Aerial Vehicle，简称为UAV)简称为“无人机”，已应用到某些特定的场景中，可以执行诸如高空摄像、无人探测侦察、测量测绘、公路勘测、城市规划、生态环保监控、科学考察、石油勘探、航空遥感、边防巡逻、森林防火、灾情评估等任务。
为了进一步拓展无人机的应用范围，第三代合作伙伴计划(3rd Generation Partnership Project，简称为3GPP)在对“无人机的增强支持”项目的讨论中提出了使蜂窝网络为无人机提供满足需求的服务更加标准化的研究，并且认为蜂窝网络提前确定出无人机的飞行路径，进而确定出无人机在飞行过程中会经过哪些基站有助于提升无人机的移动性。相关技术并没有提供在基站获取无人机的飞行路径的方案，因此需要提出一种新的方案，来解决基站如何获取无人机的飞行路径的问题。

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发明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、本发明的一些方面相一致的装置和方法的例子。
本公开中，无人机为接入蜂窝网络的蜂窝网络无人机。
图1A是根据一示例性实施例示出的一种无人机飞行信息的传输方法的流程图，图1B是根据一示例性实施例示出的一种无人机飞行信息的传输方法的场景图；该无人机飞行信息的传输方法可以应用在核心网设备上，如图1A所示，该无人机飞行信息的传输方法包括以下步骤101-102：
在步骤101中，从无人机管理平台获取无人机的飞行路径。
在一实施例中，无人机管理平台可以理解为一个用于控制和管理无人机的平台，例如，可以通过无人机管理平台设置无人机的飞行路径，由此实现无人机按照规划好的飞行路线飞行。
在一实施例中，无人机管理平台在设定无人机的飞行路径之后，可直接将飞行路径发送至核心网设备，由此核心网设备可接收到无人机管理平台发送的无人机的飞行路径。
在一实施例中，核心网设备还可主动向无人机管理平台发送第一请求消息，并在第一请求消息中携带无人机的标识信息，请求无人机管理平台告知无人机的飞行路径，如果无人机管理平台具有对应无人机的飞行路径，则可在接收到第一请求消息后
将对应无人机的飞行路径发送给核心网设备，如果没有对应无人机的飞行路径，则可告知核心网设备其没有设置无人机的飞行路径。
在一实施例中，通常无人机的飞行模式是固定模式时，无人机管理平台可为无人机预先设置好飞行路径，而无人机的飞行模式是动态模式时，也即由用户通过控制器对无人机进行实时遥控时，无人机管理平台不能预先设置好飞行路径。
在步骤102中，向对无人机的飞行信息有需求的基站发送无人机的飞行信息，飞行信息基于飞行路径得到。
在一实施例中，飞行信息可以包括无人机的飞行路径和无人机的标识信息。
在一实施例中，飞行信息可以包括包括无人机对应的基站列表，基站列表中记录有无人机在飞行路径上的可接入基站。
在一实施例中，对无人机的飞行信息有需求的基站可以理解为请求无人机的飞行信息的基站；在又一实施例中，对无人机的飞行信息有需求的基站可以理解为无人机的当前接入基站和/或无人机基于飞行路径飞行时可能会接入的可接入基站。
在一实施例中，核心网设备可直接将飞行信息发送至无人机当前所接入的基站和/或无人机在飞行路径上的可接入基站；在一实施例中，核心网设备还可在接收到基站发送的第二请求消息时，再将基站列表发送给发送第二请求消息的基站。
在一实施例中，核心网设备将基站列表发送给一个基站后，这个基站在无人机接入时，即可根据基站列表确定出可能服务该无人机的下一个基站，进而与可能的下一个基站进行资源交互，例如，基站列表中指示无人机可能依次接入基站1、基站2、基站3、基站4，则基站1在无人机接入时，可以预先判断出无人机可能会再切换至基站2，因此可以与基站2之间提前交互无人机的信息，如无人机的上下文信息等，由此为无人机提供更好的移动性服务。
在一示例性场景中，如图1B所示，在图1B所示的场景中，包括无人机管理平台10、无人机20、核心网设备30、至少一个基站40等，其中，无人机管理平台10在设定无人机20的飞行路径之后，可将飞行路径发送给核心网设备30，核心网设备30基于该飞行路径可确定出无人机20按照飞行路径飞行时可能会经过并接入的可接入基站，并将可接入基站发送给基站40，基站40在无人机20接入时可基于可接入基站确定出无人机的下一个可接入基站，进而提前进行资源协商以及准备切换，提高了无人机20的移动性性能。
本实施例通过上述步骤101-步骤103，核心网设备可从无人机管理平台获取无人机的飞行路径，并向对无人机的飞行信息有需求的基站发送无人机的飞行信息，如
向无人机的当前接入基站或者无人机的可接入基站发送无人机的飞行信息，由此实现为在无人机接入一个基站时，这个基站可以提前与下一个可能服务无人机的基站进行资源的协商，有助于基站基于该飞行路径提升无人机的移动性。
具体如何无人机飞行信息的传输，请参考后续实施例。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2是根据一示例性实施例示出的一种无人机飞行信息的传输方法中各个通信实体之间的交互流程图一；本实施例利用本公开实施例提供的上述方法，以各个通信实体进行交互，使得基站能够获取无人机的飞行信息为例进行示例性说明，如图2所示，包括如下步骤：
在步骤201中，无人机管理平台向核心网设备发送无人机的飞行路径。
在一实施例中，无人机管理平台在为无人机设定好飞行路径之后，可向所连接的核心网发送无人机的飞行路径。
在步骤202中，核心网设备向基站发送无人机的飞行信息。
在一实施例中，核心网设备可直接向基站发送无人机的飞行路径和无人机的标识信息。
在一实施例中，核心网设备还可基于每一个基站的覆盖范围以及无人机的飞行路径确定出无人机依照飞行路径飞行时的可接入基站。在一实施例中，可接入基站可以理解为无人机基于飞行路径飞行时可接入的基站，例如，无人机的飞行路径上经过基站1、基站2、基站3、基站4、基站5的覆盖区域，则可接入基站可以为基站1、基站2、基站3、基站4、基站5，但是无人机在飞行过程中可能只接入了基站1、基站3、基站5，也即，可接入基站是无人机可能会接入但是不是必需接入的基站。在一实施例中，核心网设备可将可接入基站形成一个基站列表。
在一实施例中，核心网设备可将可接入基站组成的基站列表和无人机的标识信息发送给对无人机的飞行信息有需求的基站。
在一实施例中，核心网设备可通过与基站之间的接口，比如S1接口，将基站列表发送给每一个可接入基站和无人机当前所接入的基站。
在步骤203中，基站基于无人机的飞行信息，确定无人机在飞行路径上的下一个可接入基站。
本实施例中，公开了一种传输无人机的飞行路径的实现方式，无人机管理平台可在设定无人机的飞行路径后即将飞行路径发送给核心网设备，核心网设备将飞行信息发送给有需求的基站，由此可实现基站基于该信息提前确定出可能服务无人机的下
一个基站，提前与其进行资源的协商，为无人机用户提供更好的移动性服务。
图3是根据一示例性实施例示出的又一种无人机飞行信息的传输方法中各个通信实体之间的交互流程图二；本实施例利用本公开实施例提供的上述方法，以各个通信实体进行交互，使得基站能够获取无人机的飞行信息为例进行示例性说明，如图3所示，包括如下步骤：
在步骤301中，无人机管理平台向核心网设备发送无人机的飞行路径。
在步骤302中，核心网设备接收基站发送的第二请求消息。
在一实施例中，基站在确定自己在为无人机提供服务时，如无人机接入基站时，可主动向核心网设备发送第二请求消息，请求核心网设备告知该无人机的可接入基站，第二请求消息中可以携带所请求的无人机的标识信息。
在步骤303中，核心网设备向发送第二请求消息的基站返回无人机的飞行信息。
在一实施例中，核心网设备可通过与基站之间的接口，比如S1接口，将基站列表发送给发送第二请求消息的基站。
在步骤304中，基站基于无人机的飞行信息，确定无人机在飞行路径上的下一个可接入基站。
本实施例中，公开了一种传输无人机的飞行路径的实现方式，无人机管理平台可在设定无人机的飞行路径后即将飞行路径发送给核心网设备，核心网设备可在接收到基站的第二请求消息后将无人机的飞行信息返回给基站，由此可实现基站基于该信息提前确定出可能服务无人机的下一个基站，提前与其进行资源的协商，为无人机用户提供更好的移动性服务。
图4是根据一示例性实施例示出的又一种无人机飞行信息的传输方法中各个通信实体之间的交互流程图三；本实施例利用本公开实施例提供的上述方法，以各个通信实体进行交互，使得基站能够获取无人机的飞行信息为例进行示例性说明，如图4所示，包括如下步骤：
在步骤401中，基站向核心网设备发送第二请求消息。
在一实施例中，基站在确定自己在为无人机提供服务时，如无人机接入基站时，可主动向核心网设备发送第二请求消息，请求核心网设备告知该无人机的可接入基站。
在一实施例中，第二请求消息中可以携带无人机的标识信息。
在步骤402中，核心网设备基于第二请求消息，向无人机管理平台发送第一请求消息。
在一实施例中，核心网设备基于第二请求消息中的无人机的标识信息，向无人机
管理平台发送第一请求消息，第一请求消息中携带有无人机的标识信息。
在步骤403中，无人机管理平台向核心网设备发送对应无人机的飞行路径。
在一实施例中，如果无人机管理平台中没有设置对应无人机的飞行路径，则可向核心网设备返回没有无人机的飞行路径的指示信息，以便核心网设备向基站返回无法确定无人机的可接入基站的指示信息。
在步骤404中，核心网设备向基站返回无人机的飞行信息。
在步骤405中，基站基于无人机的飞行信息，确定无人机在飞行路径上的下一个可接入基站。
本实施例中，公开了一种基于请求的传输无人机的飞行路径的方式，在基站需要获取无人机的可接入基站时，主动向核心网设备请求，而核心网设备再向无人机管理平台请求，避免了核心网设备向所有基站发送基站列表，而有些基站并不需要该信息导致的信令浪费。
图5是根据一示例性实施例示出的一种无人机飞行信息的传输方法的流程图；该无人机飞行信息的传输方法可以应用在基站上，如图5所示，包括如下步骤：
在步骤501中，从核心网设备获取无人机对应的飞行信息。
在一实施例中，基站可在需要无人机的可接入基站信息时，主动向核心网设备发送第二请求消息，并接收核心网设备基于第二请求消息返回的无人机对应的基站列表。
在一实施例中，核心网设备也可主动向所确定出的可接入基站发送无人机对应的基站列表，由此基站可接到核心网设备发送的无人机对应的基站列表。
在步骤502中，基于无人机对应的飞行信息，确定无人机可切换至的下一个可接入基站。
在一实施例中，基站在无人机接入时，可基于无人机俄飞行信息确定出可切换至的下一个可接入基站，并与下一个可接入基站进行资源协商操作。
在一实施例中，无人机的飞行信息包括无人机的飞行路径时，可参考图6所示实施例确定出下一个可接入基站。
在一实施例中，无人机的飞行信息包括无人机对应的基站列表时，可直接基于基站列表中记录的可接入基站，确定无人机可切换至的下一个可接入基站，例如，直接将基站列表中记录的与本基站相邻的可接入基站确定为无人机可切换至的下一个可接入基站。
在一示例性场景中，如图1B所示，在图1B所示的场景中，包括无人机管理
平台10、无人机20、核心网设备30、至少一个基站40等，其中，无人机管理平台10在设定无人机20的飞行路径之后，可将飞行路径发送给核心网设备30，核心网设备30基于该飞行路径可确定出无人机20按照飞行路径飞行时可能会经过并接入的可接入基站，并将可接入基站发送给基站40，基站40在无人机20接入时可基于可接入基站确定出下一个可能服务无人机的基站，进而提前进行资源协商以及准备切换，提高了无人机20的移动性性能。
本实施例通过上述步骤501-步骤502，基站可从核心网设备获取无人机对应的基站列表，进而为无人机提供更好的移动性服务。
图6是根据一示例性实施例示出的又一种无人机飞行信息的传输方法的流程图；本实施例利用本公开实施例提供的上述方法，以飞行信息为无人机的飞行路径时，基站如何确定下一个可接入基站为例进行示例性说明，如图6所示，包括如下步骤：
在步骤601中，若飞行信息包括无人机的飞行路径，则向相邻基站发送获取基站位置信息的第三请求消息。
在一实施例中，飞行路径可以由多个坐标点组成，在有无人机接入时，基站可以向相邻基站发送第三请求消息，第三请求消息用于基站获取其相邻基站的位置信息。
在步骤602中，接收相邻基站基于第三请求消息返回的基站位置信息。
在步骤603中，将基站位置信息与飞行路径匹配的基站确定为之间的无人机可切换至的下一个可接入基站。
在一实施例中，基站可基于相邻基站的基站位置信息与飞行路径的位置关系，例如，无人机的飞行路径经过无人机的位置信息所标识的位置，或者相邻基站的覆盖范围包括无人机的飞行路径的一部分，等等，确定出哪些相邻基站与无人机的飞行路径匹配，并将匹配的基站确定为无人机可切换至的下一个可接入基站，无人机的下一个可接入基站并不限定为一个。
本实施例中，公开了基站如何基于无人机的飞行路径确定出下一个可接入基站，进而实现无人机的当前接入基站可以提前与下一个可能服务无人机的下一个可接入基站进行资源的协商，有助于基站基于该飞行路径提升无人机的移动性。
