为了应对无线宽带技术的挑战，保持3GPP网络的领先优势，3GPP标准组制定了下一代移动通信网络架构(next generation system)，称为5G网络架构。该架构不但支持3GPP标准组定义的无线技术(如LTE等)接入5G核心网(5G core network，5GC)，而且支持non-3GPP接入技术通过non-3GPP交互功能(non-3GPP interworking function，N3IWF)、可信任non-3GPP网关功能(trusted non-3GPP gateway function，TNGF)、可信任WLAN交互功能(trusted WLAN interworking function，TWIF)或下一代接入网关(next generation packet data gateway，NG-PDG)接入5GC。其中核心网功能分为用户面网元功能(user plane function，UPF)与控制面网元功能(control plane function，CP)。UPF主要负责分组数据包的转发、服务质量(quality of service，QoS)控制、计费信息统计等。CP主要负责用户注册认证、移动性管理及向UPF下发数据包转发策略、QoS控制策略等，可进一步细分为接入与移动性管理功能(access and mobility management function，AMF)与会话管理功能(session management function，SMF)。

UAV在执行相应的任务时，可能会沿着固定的路径飞行，如进行电力网络巡检等。UAV一般与RAN进行无线资源控制(radio resource control，RRC)建立、RRC重建立、RRC重配置等情况下，将当前飞行路径信息可用(flightPathInfoAvailable)的指示信息携带在RRC建立完成(RRCSetupComplete)消息、RRC恢复完成(RRCResumeComplete)消息、RAN切换场景中的RRC重配置完成(RRCReconfigurationComplete)消息或者RRC重建立完成(RRCReestablishmentComplete)消息等中。若是UAV在飞行过程中飞行路径发生了变化或更新，则不能及时地将飞行路径发生了变化或更新的信息上报给RAN，可能会导致RAN的决策失误。因此，本申请提供一种UAV可以及时上报飞行路径更新的方法，如图3所示。
具体地，下文中将飞行路径发生了改变或变化或更新等统一表示为飞行路径发生更新。

具体地，上述信息#4可以是第三信息的一例。
具体地，上述信息#4用于指示UAV可以进行飞行路径更新可用指示，即信息#5的上报。
具体地，上述信息#4可以是RAN通过其它配置消息(otherConfig)发送的。
步骤S318，当UAV当前的飞行路径发生更新时，UAV向RAN发送信息#5，具体地，RAN接收该信息#5。
示例性地，更新后的飞行路径可以记为飞行路径#2，该飞行路径#2可以是第二移动路径的一例。
具体地，上述信息#5可以是第二信息的一例。
具体地，上述信息#5用于指示UAV的飞行路径已更新，或者，上述信息#5用于向RAN指示更新后的飞行路径是可用的。或者，上述信息#5还用于指示UAV在飞行路径#2的起点和终点之间移动的平均速度，或者，上述信息#5还用于指示UAV在飞行路径#2的起点和终点之间移动的距离，或者，上述信息#5还用于指示UAV在飞行路径#2的相邻两个航点之间移动的平均速度，或者，上述信息#5还用于指示UAV在飞行路径#2的相邻两个航点之间移动的距离等。
具体地，上述信息#5可以是UAV携带在UE辅助信息(UEAssistantInformation)中发送的。
应理解，上述信息#5可以是基于上述信息#4发送的，也可以是UAV自发地上报的，本申请对此不作限定。
可选地，若上述UAV在向上述RAN发送了上述信息#5之后，该UAV的飞行路径#2被取消了，则上述UAV还可以向RAN指示接下来需执行的飞行路径，例如，继续执行飞行路径更新前的飞行路径#1。或者，上述UAV也可以向RAN指示该UAV的飞行任务取消。
一种可能的实现方式中，上述信息#5还可以包括如下至少一项信息#1：
发生改变的航点数量、发生改变的航点、发生改变的航点比例、UAV到达航点的时间发生改变的航点数量、UAV到达航点的时间发生改变的航点、UAV到达航点的时间发生改变的航点比例、UAV到达航点的最大位置偏差、UAV到达航点的最大时间偏差等。
具体地，上述发生改变的航点数量是UAV向RAN指示有多少航点会发生改变；上述发生改变的航点是UAV向RAN指示哪些航点会发生改变；上述发生改变的航点比例是UAV向RAN指示会发生改变的航点的比例，该发生改变的航点的比例可以是会发生改变的航点数量占UAV的飞行路径#1的总航点数量的比例，或者，会发生改变的航点的比例也可以是UAV发生改变的航点数量占UAV飞行过程中所剩余航点数量的比例；上述UAV到达航点的时间发生改变的航点数量是UAV向RAN指示有多少航点的UAV到达时间会发生改变；上述UAV到达航点的时间发生改变的航点是UAV向RAN指示哪些航点的UAV到达时间会发生改变；上述UAV到达航点的时间发生改变的航点比例是UAV向RAN指示有多少航点的UAV到达时间会发生改变的航点的比例；上述UAV到达航点的最大位置偏差是UAV向RAN指示会发生改变的航点的位置与该航点的原位置的最大偏差；上述UAV到达航点的最大时间偏差是UAV向RAN指示会发生改变的航点的到达时间与该航点的原到达时间的最大偏差。

UAV发送上述信息#5中的至少一项信息#1时的速度、高度或位置等。
RAN可以基于上述信息#5判断是否指示UAV更新飞行路径。
更近一步地，RAN还可以基于上述信息#5中的信息#2配置多套信息#8。示例性地，当UAV上报的信息#5中的信息#2对应的UAV的高度为100m时，RAN为UAV配置一套对应UAV的高度为100m的信息#8；当UAV上报的信息#5中的信息#2对应的UAV的高度为200m时，RAN为UAV配置一套对应UAV的高度为200m的信息#8。RAN所配置的多套信息#8可以包括在同一配置信息中，也可以在不同的配置信息中。对于信息#8的具体描述如下文所述。
另外，上述信息#5可以携带在其它消息中，例如RRC重配置完成消息等。
另一种可能的实现方式为，RAN在接收到上述信息#3之后，可以向UAV发送信息#8。
具体地，该信息#8可以称为飞行路径更新配置信息，可以携带在RRC重配置消息或单独的信令中，本申请对此不作限定。该信息#8可以是第七信息的一例。
该信息#8可以包括以下三个方面的信息中的至少一个方面的信息：
(1)第一方面的信息是对发生改变的航点数量的限制信息：
1)发生改变的航点数量不超过第一阈值。
具体地，可以设置上述第一阈值为3，当UAV发生改变的航点数量为4时，UAV触发上述信息#3的上报；示例性地，UAV的飞行路径#1的航点数量为20，UAV在飞行过程中，还剩余10个航点，上述第一阈值可以是对上述飞行路径#1的航点数量的限制，也可以是对UAV飞行过程中所剩余航点数量的限制，本申请对此不作限定。
也就是说，当UAV发生改变的航点数量不超过上述第一阈值时，UAV不触发上报更新后的飞行路径#2；当UAV发送改变的航点数量超过上述第一阈值时，UAV触发上报更新后的飞行路径#2。
2)发生改变的航点比例不超过第二阈值。

3)指定的航点。
RAN指定UAV的飞行路径#1的航点中的部分航点，当RAN所指定的航点中的部分或者全部发生改变时，UAV触发上述信息#3的上报；示例性地，UAV的飞行路径#1的航点数量为20，RAN指定该飞行路径#1的20个航点中的航点1、航点3、航点7、航点10。当航点1、航点3、航点7、航点10中的部分或者全部发送改变时，UAV触发上述信息#3的上报。其中，上述RAN所指定的航点是RAN所感兴趣的航点。
也就是说，当RAN所指定的航点中的部分或全部航点不发生改变时，UAV不触发上报更新后的飞行路径#2；当RAN所指定的航点中的部分或全部航点发生改变时，UAV触发上报更新后的飞行路径#2。
(2)第二方面的信息是对发生改变的航点位置的限制信息：
1)UAV到达航点的位置不超过第一位置偏差。
具体地，可以设置上述第一位置偏差为50米(m)，当UAV到达航点的位置与该航点的原位置的偏差为60m时，UAV触发上述信息#3的上报。
具体地，对于发生改变的航点的数量可以参照上述第一方面的对发生改变的航点数量的限制信息，此处不再赘述。
2)UAV到达航点的位置不超过第一区域。
具体地，RAN可以向UAV指示该第一区域，当UAV到达航点的位置超出上述第一区域时，UAV触发上述信息#3的上报。

也就是说，当UAV到达航点的时间发生改变的航点数量不超过第三阈值时，UAV不触发上报更新后的飞行路径#2；当UAV到达航点的时间发生改变的航点数量超过第三阈值时，UAV触发上报更新后的飞行路径#2。
具体地，UAV到达航点的时间发生改变的航点数量与上述第一方面的发生改变的航点数量有可能相同，也有可能不同，本申请对此不作限定。
具体地，对于发生改变的航点数量可以参照上述第一方面的对发生改变的航点数量的限制信息，和/或，对于发生改变的航点的位置可以参照上述第二方面的对发生改变的航点位置的限制信息，此处不再赘述。
2)UAV到达航点的时间发生改变的航点比例不超过第四阈值。

也就是说，当UAV到达航点的时间发生改变的航点比例不超过第四阈值时，UAV不触发上报更新后的飞行路径#2；当UAV到达航点的时间发生改变的航点比例超过第四阈值时，UAV触发上报更新后的飞行路径#2。
具体地，对于发生改变的航点数量可以参照上述第一方面的对发生改变的航点数量的限制信息，和/或，对于发生改变的航点的位置可以参照上述第二方面的对发生改变的航点位置的限制信息，此处不再赘述。
3)UAV在指定航点的到达时间发生改变。
RAN指定UAV的飞行路径#1的航点中的部分航点，当RAN所指定的航点对应的时间中的部分或者全部发生改变时，UAV触发上述信息#3的上报；示例性地，UAV的飞行路径#1的航点数量为20，RAN 指定该飞行路径#1的20个航点中的航点1、航点3、航点7、航点10。当航点1、航点3、航点7、航点10对应的到达时间中的部分或者全部发生改变时，UAV触发上述信息#3的上报。其中，上述RAN所指定的航点是RAN所感兴趣的航点。
也就是说，当RAN所指定的部分或全部航点的UAV到达时间不发生改变时，UAV不触发上报更新后的飞行路径#2；当RAN所指定的部分或全部航点的UAV到达时间发生改变时，UAV触发上报更新后的飞行路径#2。
4)UAV到达航点的时间偏差不超过第一时间偏差。
具体地，可以设置上述第一时间偏差为5分钟(min)，当UAV到达航点的时间与UAV到达该航点的原时间的时间偏差为6min时，UAV触发上述信息#3的上报。

5)RAN在不同时段的负载状况。
具体地，RAN可以向UAV指示RAN在不同时间段的负载状况，当UAV到达航点的时间处于RAN的低负载状态的时间段，UAV触发上述信息#3的上报；或者，当UAV到达航点的时间处于RAN的高负载状态的时间段，UAV不触发上述信息#3的上报。
另外，上述信息#8可以携带在RRC重配置消息中。
通过RAN向上述UAV发送上述信息#8，可以对UAV上报更新后的飞行路径#2的触发条件进行限制，从而可以避免UAV对飞行路径的频繁更新，节省空口资源。
步骤S320，RAN在获知UAV更新后的飞行路径是可用的情况下，重复上述步骤S312以及上述步骤S314，从而获得UAV的飞行路径的信息。
具体地，上述步骤S320的信息#2可以是第四信息的一例，上述步骤S320的信息#3可以是第一信息的一例。
另外地，上述步骤S320的信息#2可以用于指示UAV进行差分上报。也就是说，上述步骤S320的信息#2可以用于指示UAV上报与最新的飞行路径不同的地方的飞行路径的信息。
可选地，也可以是UAV自主进行差分上报，不需RAN指示。
下文对UAV如何进行差分上报进行详细描述：
第一种差分上报的方式：上报固定长度的序列。
具体地，可以将上报的序列长度设计为航点数量的最大值。示例性地，根据当前要求，上报的飞行路径所包括的航点数量的最大值为20，此时进行差分上报的序列长度为20。本申请对航点数量的最大值不作限定，下文以航点数量的最大值为20为例进行描述。
具体地，序列中的比特位与飞行路径的航点一一对应。如果飞行路径的航点数量A小于航点数量的最大值N，或者，如果飞行路径的航点数量A小于序列中的比特位数量N，那么可以以序列中N个比特位中最靠前的A个比特位分别代表飞行路径的A个航点。可选地，也可以以序列中N个比特位中最靠后的A个比特位分别代表飞行路径的A个航点，或者，也可以以序列中N个比特位中中间的A个比特位分别代表飞行路径的A个航点。本申请对序列中代表A个航点的A个比特位不作限定，下文以序列中N个比特位中最靠前的A个比特位分别代表飞行路径的A个航点为例进行描述。
具体地，第一移动路径包括M个航点，第二移动路径包括P个航点。其中，上述N个比特位中的P个比特位与该P个航点一一对应。UAV根据上述M个航点与上述P个航点确定至少一个比特位；UAV将该至少一个比特位设置为第一值，并将上述N个比特位中除该至少一个比特位之外的比特位设置为第二值。
具体地，上述第一值可以为1，上述第二值可以为0，本申请对此不作限定。
示例性地，UAV对比更新的飞行路径(即上述第二移动路径)与上次上报的飞行路径(即上述第一移动路径)的差别，如果更新的飞行路径中的某一航点发生改变，则将该航点对应的序列中的比特位设置为1；如果更新的飞行路径中的某一航点未发生改变，则将该航点对应的序列中的比特位设置为0。
具体地，上述某一航点发生改变可以是：该航点的航点位置发生改变、UAV到达该航点的时间发生改变，UAV到达该航点的顺序发生改变、该航点在第二移动路径中被删除、该航点在第二移动路径中被添加等。
具体地，更新的飞行路径中的某一航点发生改变可以分为以下三种情况：
(1)更新的飞行路径中的航点数量相比于上次上报的飞行路径中的航点数量不变。
在这种情况下，UAV将更新的飞行路径中的发生改变的航点对应的比特位设置为1，更新的飞行路径中的未发生改变的航点对应的比特位设置为0。
示例性地，飞行路径中的航点数量为10，其中，UAV通过对比发现更新的飞行路径中的航点3、航点5、航点7发生改变，那么UAN进行差分上报的序列如下表1所示。
表1
具体地，可以通过以下形式#1进行信息设计，该信息设计的形式#1为一种示例，本申请对具体的信息设计的形式不作限定：
其中，FlightPathInfoBitmap表示的是上述表1所示的序列。flightPath是一个序列，包括发生改变的航点，例如，根据上表1所示的序列，发生改变的航点为航点3、航点5、航点7，那么flightPath中包括发生改变的三个航点：航点3、航点5、航点7。wayPointLocation表示的是发生改变的航点的信息。例如，根据上表1所示的序列，发生改变的航点为航点3、航点5、航点7，那么wayPointLocation中包括航点3、航点5、航点7更新的航点信息，例如，wayPointLocation中包括更新的航点3、航点5、航点7的位置和/或更新的UAV到达航点3、航点5、航点7的时间等。
可选地，若是不能保证wayPointLocation中所包括的航点3、航点5、航点7更新的航点信息是按照航点3、航点5、航点7的顺序依次填入的，那么wayPointLocation中包括五个航点的航点信息，即航点3至航点7的所有航点的航点信息。其中，航点3、航点5、航点7的航点信息与上次上报的飞行路径中的航点3、航点5、航点7的航点信息不同，航点4、航点6的航点信息与上次上报的飞行路径中的航点4、航点6的航点信息相同。
(2)更新的飞行路径中的航点数量相比于上次上报的飞行路径中的航点数量减少。
在这种情况下，由于从所减少的航点开始，后面航点所对应的比特位与上次上报的飞行路径中的航点所对应的比特位不同，UAV从更新的飞行路径中所减少的航点对应的比特位开始，将后面航点对应的比特位都设置为1。
示例性地，上次上报的飞行路径中的航点数量为10，删除上次上报的飞行路径中的航点3，更新的飞行路径中的航点数量为9，UAV通过对比发现更新的飞行路径中的航点3、航点4、航点5、航点6、航点7、航点8、航点9发生改变，那么UAN进行差分上报的序列如下表2所示。
表2
其中，由于在删除上次上报的飞行路径中的航点3之后，更新的飞行路径中的航点10的航点信息已经不存在，信息设计的上述形式#1中的wayPointLocation中包括七个航点更新的航点信息，即航点3、航点4、航点5、航点6、航点7、航点8、航点9更新的航点信息。
(3)更新的飞行路径中的航点数量相比于上次上报的飞行路径中的航点数量增加。
在这种情况下，由于从所增加的航点开始，后面航点所对应的比特位与上次上报的飞行路径中的航点所对应的比特位不同，UAV从更新的飞行路径中所增加的航点对应的比特位开始，将后面航点对应的比特位都设置为1。
示例性地，上次上报的飞行路径中的航点数量为10，在上次上报的飞行路径中的航点9与航点10之 间增加新的航点11，更新的飞行路径中的航点数量为11，UAV通过对比发现更新的飞行路径中的航点10、航点11发生改变，那么UAN进行差分上报的序列如下表3所示。
表3
其中，在增加上次上报的飞行路径中的航点11之后，信息设计的上述形式#1中的wayPointLocation中包括两个航点更新的航点信息，即航点10、航点11更新的航点信息。
第二种差分上报的方式：上报可变长度的序列。
具体地，上报的序列长度N是根据上次上报的飞行路径的航点数量M或更新的飞行路径的航点数量P确定的，而不是上报固定长度的序列。上报的序列的最大长度为航点数量的最大值。示例性地，根据当前要求，上报的飞行路径所包括的航点数量的最大值为20，此时进行差分上报的可变长度序列的最大长度为20，本申请对航点数量的最大值不作限定。
具体地，序列中的比特位与飞行路径的航点一一对应。
示例性地，UAV对比更新的飞行路径与上次上报的飞行路径的差别，如果更新的飞行路径中的某一航点发生改变，则将该航点对应的序列中的比特位设置为1；如果更新的飞行路径中的某一航点未发生改变，则将该航点对应的序列中的比特位设置为0。
具体地，上述某一航点发生改变可以是：该航点的航点位置发生改变、UAV到达该航点的时间发生改变，UAV到达该航点的顺序发生改变、该航点对应的比特位发生改变等。
具体地，更新的飞行路径中的某一航点发生改变可以分为以下三种情况：
(1)更新的飞行路径中的航点数量相比于上次上报的飞行路径中的航点数量不变。
在这种情况下，UAV将更新的飞行路径中的发生改变的航点对应的比特位设置为1，更新的飞行路径中的未发生改变的航点对应的比特位设置为0。
示例性地，飞行路径中的航点数量为10，其中，UAV通过对比发现更新的飞行路径中的航点3、航点5、航点7发生改变，那么UAN进行差分上报的序列如下表4所示。
表4
具体地，可以通过以下形式#2进行信息设计，该信息设计的形式#2为一种示例，本申请对具体的信息设计的形式不作限定：
其中，FlightPathInfoBitmap表示的是上述表4所示的序列。flightPath是一个序列，包括发生改变的航点，例如，根据上表4所示的序列，发生改变的航点为航点3、航点5、航点7，那么flightPath中包括发生改变的三个航点：航点3、航点5、航点7。wayPointLocation表示的是发生改变的航点的信息。例如，根据上表4所示的序列，发生改变的航点为航点3、航点5、航点7，那么wayPointLocation中包括三个航点更新的航点信息，即航点3、航点5、航点7更新的航点信息，例如，wayPointLocation中包括更新的航点3、航点5、航点7的位置和/或更新的UAV到达航点3、航点5、航点7的时间等。maxWayPoint表示的是上报的飞行路径所包括的航点数量的最大值，也即上报的可变序列长度的最大长度。
可选地，若是不能保证wayPointLocation中所包括的航点3、航点5、航点7更新的航点信息是按照航点3、航点5、航点7的顺序依次填入的，那么wayPointLocation中包括五个航点的航点信息，即航点3至航点7的所有航点的航点信息。其中，航点3、航点5、航点7的航点信息与上次上报的飞行路径中的航点3、航点5、航点7的航点信息不同，航点4、航点6的航点信息与上次上报的飞行路径中的航点 4、航点6的航点信息相同。
(2)更新的飞行路径中的航点数量相比于上次上报的飞行路径中的航点数量减少。
在这种情况下，由于从所减少的航点开始，后面航点所对应的比特位与上次上报的飞行路径中的航点所对应的比特位不同，UAV从更新的飞行路径中所减少的航点对应的比特位开始，将后面航点对应的比特位都设置为1。
示例性地，上次上报的飞行路径中的航点数量为10，删除上次上报的飞行路径中的航点3，更新的飞行路径中的航点数量为9，UAV通过对比发现更新的飞行路径中的航点3、航点4、航点5、航点6、航点7、航点8、航点9发生改变，那么UAN进行差分上报的序列如下表5所示。
表5
其中，由于在删除上次上报的飞行路径中的航点3之后，更新的飞行路径中的航点10的航点信息已经不存在，信息设计的上述形式#1中的wayPointLocation中包括七个航点更新的航点信息，即航点3、航点4、航点5、航点6、航点7、航点8、航点9更新的航点信息。
(3)更新的飞行路径中的航点数量相比于上次上报的飞行路径中的航点数量增加。
在这种情况下，由于从所增加的航点开始，后面航点所对应的比特位与上次上报的飞行路径中的航点所对应的比特位不同，UAV从更新的飞行路径中所增加的航点对应的比特位开始，将后面航点对应的比特位都设置为1。
示例性地，上次上报的飞行路径中的航点数量为10，在上次上报的飞行路径中的航点9与航点10之间增加新的航点11，更新的飞行路径中的航点数量为11，UAV通过对比发现更新的飞行路径中的航点10、航点11发生改变，那么UAN进行差分上报的序列如下表6所示，此时UAV上报的序列长度添加了一个比特位。
表6
其中，在增加上次上报的飞行路径中的航点11之后，信息设计的上述形式#2中的flightPath中包括两个航点更新的航点信息，即航点10、航点11更新的航点信息。
通过上述两种差分上报的方式，可以实现UAV向RAN指示发生改变的航点的信息，实现飞行路径的更新，并且可以节省信令开销。
另外地，通过上述两种差分上报的方式，当某一航点的航点信息未发生改变，仅仅是指示该航点的比特位发生了改变的情况下，仍然需要重新上报该行点的航点信息，导致额外的信令开销。
因此，本申请引入新的信息元素(information element，IE)，例如，下文的waypointInLastReportedFlightPath。该WaypointInLastReportedFlightPath为上次上报的飞行路径中的航点索引，用于指示上次上报的飞行路径中的航点。
具体地，可以通过以下形式#3进行信息设计，该信息设计的形式#3为一种示例，本申请对具体的信息设计的形式不作限定：
其中，FlightPathInfoBitmap表示的是上述表1至表6所示的序列。flightPath是一个序列，包括发生改变的航点。wayPointLocation表示的是发生改变的航点的信息。waypointInLastReportedFlightPath为上次 上报的飞行路径中的航点索引，用于指示上次上报的飞行路径中的航点。例如，将waypointInLastReportedFlightPath设为3，则指示上次上报的飞行路径中的第3个航点。
其中，某一个航点的waypointInLastReportedFlightPath与wayPointLocation任选其一进行上报。
示例性地，以上述表2所示的情况为例进行说明。上述表2为更新的飞行路径中的航点数量相比于上次上报的飞行路径中的航点数量减少的情况。上次上报的飞行路径中的航点数量为10，删除上次上报的飞行路径中的航点3，更新的飞行路径中的航点数量为9。此时，flightPath包括发生改变的航点为航点3、航点4、航点5、航点6、航点7、航点8、航点9。
具体地，wayPointLocation中包括七个航点更新的航点信息，即航点3、航点4、航点5、航点6、航点7、航点8、航点9更新的航点信息，如下表7所示。
表7
上述表7中携带的都是wayPointLocation信息。
但是更新的飞行路径中的航点3、航点4、航点5、航点6、航点7、航点8、航点9更新的航点信息与上次上报的飞行路径中的航点4、航点5、航点6、航点7、航点8、航点9、航点10是相同的。
因此，上报的信息可以如下表8所示。
表8
上述表8中携带的都是waypointInLastReportedFlightPath信息。RAN根据表8获取上次上报的飞行路径中的航点4、航点5、航点6、航点7、航点8、航点9、航点10的航点信息分别作为flightPath所包括的发生改变的航点3、航点4、航点5、航点6、航点7、航点8、航点9的航点信息，不需UAV重新上报。
通过上述方法，如果更新的飞行路径的某一航点的航点信息未发生改变，仅仅是指示该航点的比特位发生了改变的情况下，UAV可以通过引用之前上报的飞行路径的该航点的航点信息即可，无需UAV重新上报该航点的航点信息，减少信令开销。
具体地，上述步骤S320的信息#2中还可以包括RAN对UAV上报当前的飞行路径的规范。
具体地，该信息#2中还可以包括UAV所执行任务的如下至少一项信息：
飞行路径所包括的航点数量，航点的分布情况，航点的间隔，飞行路径的起点、终点，某一航点的加速、减速情况，某一航点的盘旋时间、盘旋速度，航点对应的时间为绝对时间还是相对时间、起点和终点之间的平均速度、起点和终点之间的距离、不同的起点和终点之间的距离所对应的航点数量，相邻两个航点之间的平均速度、相邻两个航点之间的距离等。
具体地，若UAV已经飞过了起点后上报上述飞行路径的起点，则UAV将当前所处的位置限定为所执行任务的起点。
具体地，上述航点的分布情况可以是飞行路径所包括的航点位置可以是均匀分布的，也可以是不均 匀分布的等。
具体地，当起始航点的对应时间为相对时间时，则后续航点的时间均采用相对时间；或者，当起始航点的对应时间为绝对时间时，则后续航点的时间均采用绝对时间。
另外，上述航点数量可以包括上述起点、终点，也可以不包括上述起点、终点，本申请对此不作限定。
通过上述实施例的技术方案，RAN可以及时地获取到UAV的飞行路径发生更新的指示信息，可以防止RAN对UAV的飞行路径发生误判。另外地，上述方法还对UAV上报的飞行路径的信息作出了一些规范，避免RAN不能准确地识别UAV上报的飞行路径。
本申请还可以提供另外一种UAV可以及时上报飞行路径更新的方法，如图4所示。

具体地，若UAV已经飞过了起点后上报上述飞行路径的起点，则UAV将当前所处的位置限定为所执行任务的起点。
具体地，上述航点的分布情况可以是飞行路径所包括的航点位置可以是均匀分布的，也可以是不均匀分布的等。
具体地，当起始航点的对应时间为相对时间时，则后续航点的时间均采用相对时间；或者，当起始航点的对应时间为绝对时间时，则后续航点的时间均采用绝对时间。
另外，上述航点数量可以包括上述起点、终点，也可以不包括上述起点、终点，本申请对此不作限定。
具体地，上述信息#6是否包括RAN对UAV上报当前的飞行路径的规范可以用1比特进行指示。当该比特位1时，指示上述信息#6包括RAN对UAV上报当前的飞行路径的规范；当该比特位0时，指示上述信息#6不包括RAN对UAV上报当前的飞行路径的规范，该比特位数以及比特位的具体数值都可以进行灵活设定，本申请对此不作限定。
步骤S418，当UAV当前的飞行路径发生更新时，UAV基于上述信息#6向RAN发送信息#7，具体地，RAN接收该信息#7。
具体地，上述信息#7也可以是第一信息的一例。
具体地，上述信息#7包括UAV更新可用的飞行路径的信息。
具体地，上述信息#7可以是UAV携带在UE辅助信息(UEAssistantInformation)中发送的。
另外地，上述信息#7可以用于指示UAV进行差分上报。也就是说，上述信息#7可以用于指示UAV上报与最新的飞行路径不同的地方的飞行路径的信息。
具体的差分上报方式可以参照上文所述，此处不再赘述。
通过上述实施例的技术方案，RAN可以及时地获取到更新后的UAV的飞行路径的信息，从而及时地对UAV的飞行路径作出判断。另外地，上述方法还对UAV上报的飞行路径的信息作出了一些规范，避免RAN不能准确地识别UAV上报的飞行路径。
UAV在飞行过程中，会出现为UAV服务的RAN切换的情况。当源RAN已经接收到UAV的飞行路径的信息，并且在切换的过程中没有将UAV的飞行路径的信息发送给目标RAN时，会导致目标RAN无法获取UAV的当前的飞行路径的信息，进而无法对UAV进行准确的控制。
为了解决上述问题，本申请提供一种RAN切换场景下飞行路径更新的方法，如图5所示。

具体地，当起始航点的对应时间为相对时间时，则后续航点的时间均采用相对时间；或者，当起始航点的对应时间为绝对时间时，则后续航点的时间均采用绝对时间。
另外，上述航点数量可以包括上述起点、终点，也可以不包括上述起点、终点，本申请对此不作限定。
具体地，上述信息#2还包括用于指示UAV进行差分上报的信息。也就是说，上述信息#2可以用于指示UAV上报与最新的飞行路径不同的地方的飞行路径的信息。

一种可能的实现方式为，该信息#2还可以包括上述信息#8。
UAV在发生改变的飞行路径#2满足上述信息#8的限制条件时，再上报更新的飞行路径#2，从而尽量减少目标RAN触发无用的飞行路径的更新。
步骤S520，源RAN触发或启动与UAV之间的Uu接口切换。
步骤S522，源RAN向UAV发送RRC重配置消息。具体地，该RRC重配置消息包括目标小区的标识信息等。
另外地，上述RRC重配置消息还包括上述信息#2。

从LTE阶段到NR阶段的部署过程中会经历很多中间阶段，进一步地演进到NR的独立组网部署。目前最常见的一种中间阶段的部署方式是4G基站(例如，eNB)与5G基站(例如，gNB)的双连接(E-UTRAN-NR dual connectivity，EN-DC)架构，如图6所示。
在这种组网情况下，不需要部署新的5G核心网，只需要对演进型分组核心网(evolved packet cire，EPC)进行升级，满足对5G业务的支持，有利于加快5G业务的部署。
在EN-DC架构下，由eNB提供控制面信令管理，所有的控制面信令都依赖于eNB进行转发。另外，由gNB辅助进行用户面数据的传输。gNB到UAV的空口信令交互主要依赖于eNB，此时的eNB可以认为是gNB到UAV之间的路由器，传递控制信令。
因此，在EN-DC架构下，eNB可以认为是主基站(master eNB，MeNB)。
UAV在接入网络时与运营商签订的协议为UAV订阅消息，该UAV订阅消息包括UAV的授权等，基站可以基于UAV订阅消息判断UAV是否合法，并向UAV下发相应的配置消息等。
然而，在EN-DC架构下，UAV与基站连接时，UAV订阅消息的管理目前没有相应的规范，导致UAV的管理比较混乱。
为解决上述问题，本申请提供一种UAV订阅消息的管理方法，如图7所示。
步骤S710，4G核心网的MME获取到UAV的订阅消息。
步骤S712，MME将UAV的订阅消息发给主基站MeNB。相应地，MeNB接收UAV的订阅消息。
具体地，上述UAV的订阅消息包括UAV的LTE订阅消息以及UAV的NR订阅消息。
步骤S714，MeNB经过判断，将UAV的LTE订阅消息用于自身处理，将UAV的NR订阅消息发送给gNB。相应地，gNB接收UAV的NR订阅消息。
具体地，MeNB可以通过辅基站(second gNB，SgNB)添加请求消息发送给gNB。
步骤S716，gNB根据UAV的NR订阅消息确定UAV的配置信息，并向MeNB发送该UAV的配置信息。
具体地，上述UAV的配置信息可以通过SgNB添加请求确认消息发送给MeNB。
步骤S718，MeNB将UAV的配置信息通过RRC重配置消息发送给UAV。
步骤S720，UAV执行RRC重配置消息，并向MeNB反馈RRC重配置完成消息。
通过上述方法，可以避免gNB对获取到的UAV的订阅消息无法进行配置的情况。
