具体实施方式
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。
图1A是根据一示例性实施例示出的一种数据传输方法的流程图，图1B是根据一示例性实施例示出的一种数据传输方法的场景图；该数据传输方法可以应用在无人机上，如图1A所示，该数据传输方法包括以下步骤101-102：
在步骤101中，确定无人机与无人机控制器之间的第一链路的链路质量、无人 机与基站之间的第二链路的链路质量，以及基站与无人机控制器之间的第三链路的链路质量。
在一实施例中，第一链路为WIFI网络通信链路，无人机可以通过WIFI网络中的第一链路直接将数据发送至无人机控制器；在一实施例中，第二链路和第三链路为移动网路通信链路，无人机可以通过移动网络中的第二链路将数据发送至基站，再由基站通过第三基站将数据发送至无人机控制器。
在一实施例中，对于第一链路、第二链路，无人机可通过检测第一链路和第二链路上传输的参考信号的信号功率确定对应链路的链路质量；在一实施例中，对于第三链路，无人机可接收无人机控制器发送的第三链路的链路质量，无人机控制器可周期性向无人机发送第三链路的链路质量，也可在接收到无人机发送的获取第三链路的链路质量的请求时向无人机发送第三链路的链路质量。
在步骤102中，基于第一链路的链路质量、第二链路的链路质量、第三链路的链路质量，确定待传输数据的数据传输链路。
在一实施例中，待传输数据可以为无人机的分组数据汇聚协议(Packet Data Convergence Protocol，简称为PDCP)的缓存器中缓存的需要发送给无人机控制器的数据包。
在一实施例中，由于WIFI网络为免费网络，移动网络为计费网络，因此可以在第一链路的链路质量比较高时，优先将WIFI网络通信链路，也即第一链路确定为数据传输链路，而在第一链路的链路质量较低，而第二链路和第三链路的链路质量都较高时，可将WIFI网络通信链路和移动网络通信链路，也即第一链路和第二链路均确定为数据传输链路，或者只将移动网络通信链路确定为数据传输链路。基于第一链路、第二链路、第三链路的链路质量，确定待传输数据的数据传输链路的具体实现方式，可参见图2-图3所示实施例的描述，这里先不详述。
在一实施例中，在确定出待传输数据的数据传输链路之后，即可通过传输链路发送该待传输数据。
在一示例性场景中，如图1B所示，以移动网络为长期演进(Long Term Evolution，简称为LTE)网络并且基站为演进型基站(eNB)为例进行示例性说明(移动网络不限制为LTE网络，还可以为5G等其他的蜂窝网络)，在图1B所示的场景中，包括eNB10、无人机20、无人机控制器30，其中，无人机20位于eNB10的覆盖范围内，并且与无人机控制器30位于同一个WIFI网络中。基于第一链路的链路质量、第二链路的链路质量和第三链路的链路质量，在一种情形下，无人机20可通过WIFI网 络中的第一链路141向无人机控制器30传输数据，当在第一链路141的链路质量比较低时，为了提升无人机20传输数据的效率，可以将部分数据或者全部数据通过第二链路142传输给eNB10，eNB10再将这部分数据或者全部数据通过第三链路143转发给无人机控制器30。有效提升了无人机20和无人机控制器30之间传输数据的效率。
无人机所接入的移动网络与WIFI网络是两个独立的通信网络，本实施例通过上述步骤101和步骤102，无人机可基于无人机与无人机控制器之间的第一链路的链路质量、无人机与基站之间的第二链路的链路质量，以及基站与无人机控制器之间的第三链路的链路质量，动态调整发送待传输数据的数据传输链路，从而可以将无人机所接入的移动网络与WIFI网络的资源更好地融合，解决了相关技术中无人机和无人机控制器之间通过WIFI网络传输数据的所导致的数据传输性能较低的问题。
具体如何传输数据的，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另一种数据传输方法的流程图；本实施例利用本公开实施例提供的上述方法，以无人机基于第一链路、第二链路、第三链路的链路质量确定数据传输链路并传输数据为例并结合图1B进行示例性说明，如图2所示，包括如下步骤：
在步骤201中，确定无人机与无人机控制器之间的第一链路的链路质量、无人机与基站之间的第二链路的链路质量，以及基站与无人机控制器之间的第三链路的链路质量，并根据第一链路、第二链路、第三链路的链路质量，对应执行步骤202，或者步骤203，或者步骤204。
在步骤202中，当第一链路的链路质量高于第一阈值时，将WIFI网络通信链路确定为数据传输链路，并通过WIFI网络通信链路发送待传输数据，流程结束。
在一实施例中，第一阈值可以为一个比较高的数值，例如，第一阈值为-60dB，第一链路的链路质量高于第一阈值可以用于指示WIFI网络的信号质量非常好，足以用来传输无人机的业务数据，因此可只将WIFI网络对应的第一链路确定为传输链路。
在步骤203中，当第一链路的链路质量低于第二阈值，第二链路的链路质量高于第四阈值并且第三链路的链路质量高于第六阈值时，将移动网络通信链路确定为数据传输链路，并通过第二链路发送待传输数据至基站，流程结束。
在一实施例中，第一链路的链路质量低于第二阈值用于指示WIFI网络的信号质量比较差，数据传输的速率非常低，而第二链路的链路质量高于第四阈值、第三链路的链路质量高于第六阈值用于指示移动网络通信链路的信号质量非常好，因此为了 避免通过WIFI网络传输数据时导致数据丢失，可只将移动网络通信链路作为数据传输链路。
在步骤204中，当第一链路的链路质量低于第一阈值并且高于第二阈值，第二链路的链路质量高于第三阈值并且不高于第四阈值，第三链路的链路质量高于第五阈值不高于第六阈值时，将WIFI网络通信链路和移动网络通信链路确定为数据传输链路。
在一实施例中，第二阈值为一个小于第一阈值的数值，例如，第二阈值为-80dB，第一链路的链路质量低于第一阈值并且高于第二阈值可以用于指示WIFI网络的信号质量一般，能够用来传输无人机的业务数据，但是传输数据的速率可能会比较低；在一实施例中，第三阈值为一个小于第四阈值的数值，第五阈值为一个小于第六阈值的数值，第二链路的链路质量高于第三阈值并且不高于第四阈值以及第三链路的链路质量高于第五阈值不高于第六阈值可以用于指示移动网络的信号质量比较好。因此，为了提高待传输数据的数据传输效率，可将待传输数据同时通过移动网络和WIFI网络进行传输。
在一实施例中，第一阈值、第二阈值、第三阈值、第四阈值、第五阈值、第六阈值可以由基站设定；在一实施例中，第一阈值、第二阈值、第三阈值、第四阈值、第五阈值、第六阈值还可以由无人机控制器设定。
在一实施例中，第三阈值可以与第五阈值相同，第四阈值可以与第六阈值相同。
在步骤205中，在将WIFI网络通信链路和移动网络通信链路确定为数据传输链路时，按照设定比例将待传输数据分为两组数据。
在一实施例中，设定比例可以由无人机控制器设定，其中，设定比例可以为一个固定值，如为2:1，设定比例还可以基于WIFI网络通信链路的链路质量和移动网络通信链路的链路质量确定，例如，WIFI网络通信链路的链路质量和移动网络通信链路的链路质量相似，则设定比例可以为1:1，WIFI网络通信链路的链路质量比移动网络通信链路的链路质量高很多，则设定比例可以为3:1，WIFI网络通信链路的链路质量比移动网络通信链路的链路质量高一点，则设定比例可以为3:2。其中，移动网络通信链路的链路质量可以基于第二链路和第三链路中质量较差的链路确定，例如，第二链路的链路质量为-80dB，而第三链路的链路质量为-75dB，则可确定移动网络通信链路的链路质量为-80dB。
在一实施例中，可按照比特为单位对待传输数据进行分组，例如，将待传输数据的前一半比特的数据划分为一组数据，后一半比特的数据划分为另一组数据，如可 以将12比特中的前6比特作为本公开中的一组数据，后6比特作为本公开中的另一组数据。
在步骤206中，将两组数据中的一组数据通过第一链路发送至无人机控制器，并将另一组数据通过第二链路发送至基站，进而由基站通过第三链路将另一组数据发送至无人机控制器。
在一实施例中，可基于WIFI网络通信链路的链路质量和移动网络通信链路的链路质量确定将哪一组数据通过移动网络通信链路发送至基站，将哪一组数据通过WIFI网络通信链路发送至无人机控制器，例如，在WIFI网络通信链路的链路质量高于移动网络通信链路的链路质量时，可将数据量多的一组数据通过WIFI网络通信链路发送至无人机控制器。
在一示例性场景中，如图1B所示，在无人机20同时能够接入到移动网络与WIFI网络的情况下，如果WIFI网络通信链路的链路质量非常好，则可只将WIFI网络通信链路作为数据传输链路，以节省使用移动网络传输数据的费用；而如果WIFI网络通信链路的链路质量一般，移动网络通信链路的链路质量也一般时，可同时将WIFI网络通信链路和移动网络通信链路作为数据传输链路，以确保无人机的数据能快速地上传至无人机控制器，而在WIFI网络通信链路的链路质量比较低，而移动网络通信链路的链路质量非常好时，可将移动网络通信链路作为数据传输链路，由此可以确保无人机20能够通过最合适的数据传输链路向无人机控制器30传输数据。
本实施例中，根据第一链路、第二链路、第三链路的链路质量来调整无人机传输数据的传输链路，从而可以确保无人机能够通过最佳的网络传输数据，有效提升无人机传输数据时的性能。
图3是根据一示例性实施例示出的又一种数据传输方法的流程图；本实施例利用本公开实施例提供的上述方法，以无人机基于无人机的待传输数据的数据量，以及WIFI网络通信链路的链路质量、移动网络通信链路的链路质量确定数据传输链路并传输数据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，确定待传输数据的数据量，当待传输数据的数据量大于第一数量阈值时，执行步骤302，当待传输数据的数据量不大于第一数量阈值时，执行步骤305。
在一实施例中，待传输数据的数据量可以基于缓存器中的缓存数据的数据量得到，例如，数据量为12比特。在一实施例中，第一数量阈值可以由无人机控制器设定，通常不会超过缓存器所能缓存的数据的数据量。
在步骤302中，将WIFI网络通信链路和移动网络通信链路确定为数据传输链路。
在一实施例中，在待传输数据的数据量大于第一数量阈值时，说明无人机的待传输数据的数据量比较大，为了尽快地传输完这些数据，可将这些数据分为两组数据，分别通过第一链路和第二链路进行发送。
在步骤303中，在将WIFI网络通信链路和移动网络通信链路确定为数据传输链路时，按照设定比例将待传输数据分为两组数据。
在步骤304中，将两组数据中的一组数据通过第一链路发送至无人机控制器，并将另一组数据通过第二链路发送至基站，进而由基站通过第三链路将另一组数据发送至无人机控制器。
在一实施例中，步骤303和步骤304的描述可参见图2所示实施例的步骤205和步骤206的描述，这里不再详述。
在步骤305中，比较第一链路、第二链路、第三链路的链路质量，当第二链路以及第三链路的链路质量均大于或者等于第一链路的链路质量时，执行步骤306，当第二链路以及第三链路的链路质量不均大于或者等于第一链路的链路质量时，执行步骤307。
在一实施例中，在数据量小于第一数量阈值时，说明待传输数据比较少，因此可只通过一个链路传输数据，比较第二链路和第三链路的链路质量与第一链路的链路质量，进而选择一个信号质量更好的链路传输数据。如果第二链路和第三链路的链路质量均大于第一链路的链路质量，则说明移动网络通信链路的链路质量好于WIFI网络通信链路的链路质量，如果第二链路和第三链路中有一个链路的质量小于第一链路的链路质量，则说明移动网络通信链路的链路质量低于WIFI网络通信链路的链路质量。
在步骤306中，将移动网络通信链路确定为数据传输链路将移动网络对应的第二链路确定为传输链路。
在步骤307中，将WIFI网络通信链路确定为数据传输链路。
本实施例中，通过待传输数据的数据量的大小，可以首先确定通过一个链路传输数据还是通过两个链路传输数据，并在确定通过一个链路传输数据时，优先选择一个信号质量更好的链路作为传输链路，从而可以将无人机所接入的移动网络与WIFI网络的资源更好地融合，解决了相关技术中无人机和无人机控制器之间通过WIFI网络传输数据的所导致的数据传输性能较低的问题，提升了无人机传输数据的性能。
