Description

通信方法、装置及存储介质
本申请要求于2022年8月3日提交中国专利局、申请号为202210926932.3、申请名称为“通信方法、装置及存储介质”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，尤其涉及一种通信方法、装置及存储介质。
背景技术
无人机(unmanned aerial vehicle，UAV)作为一种新型的飞行器，因其灵活方便，已经越来越普及。无人机在空中的通信环境与地面存在较大区别，无人机可以在基站上方飞行，与基站通过Uu口连接，视距(line of sight，LOS)径通信为主，因此无人机能接收到更多的基站的信号，且会触发无人机上报更多更频繁的测量报告。
目前，长期演进(long term evolution，LTE)系统针对无人机的测量报告的上报机制进行了改进，在测量配置中增加了触发小区数N，N大于或等于2，从而可以避免每检测到一个触发小区就上报的情况。因此，当存在N个小区，且这N个小区在触发时长(time to trigger，TTT)内均满足触发条件时，无人机向基站发送测量报告。若没有测量到N个小区在其TTT内均满足触发条件，则不会向基站发送测量报告，从而基站不会将无人机切换到其它的小区，造成切换过晚或无人链路失败(radio link failure，RLF)的情况发生。
发明内容
本申请实施例公开了一种通信方法、装置及存储介质，能够让无人机及时上报，利于提高网络设备后续决策的准确率和有效性。
第一方面，本申请实施例公开了第一种通信方法，包括：无人机接收网络设备的测量配置；当测量到满足事件触发条件的第一小区时，无人机向网络设备发送第一小区的测量报告。可以理解，在无人机接收到网络设备的测量配置之后，上报第一个测量到的满足事件触发条件的小区的测量报告，提高了测量报告上报的及时性，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，在向网络设备发送第一小区的测量报告之后，还包括：向网络设备发送N个第二小区的测量报告集，第二小区均满足事件触发条件。如此，网络设备可以基于测量报告集中各个第二小区的测量值决策是否进行重配置或切换，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，当测量到满足事件触发条件的第一小区时，还包括：将第一小区添加至触发小区列表；将第一小区添加至触发小区列表之后，还包括：当第一小区不满足事件触发条件时，无人机从触发小区列表中删除第一小区。如此，可以避免将不满足触发条件的小区的测量报告再次上报给网络设备。
在一些可能的示例中，还包括：无人机向网络设备发送第一小区的删除通知；或者无人机向网络设备发送触发小区列表中小区的测量报告。其中，删除通知用于指示第一小区从触发小区列表中删除，或者用于指示第一小区不满足事件触发条件，或者用于指示无人机已离开第一小区的覆盖范围等。可以理解，在触发小区列表中的第一小区被删除之后，可以向网络设备上报第一小区的删除通知，以避免网络设备将无人机切换为第一小区。在触发小区列表中存在除了第一小区之外的(触发)小区时，可以上报剩余未删除的触发小区的测量报告，从而网络设备可以基于当前上报的触发小区决策是否进行重配置或切换，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，测量配置还包括第一上报时长和/或第二上报时长；在无人机向网络设备发送第一小区的测量报告之后，还包括：基于第一上报时长和/或第二上报时长，无人机向网络设备发送多个第二小区的测量报告集，第二小区均满足事件触发条件。也就是说，可以基于测量配置中的上报时长向 网络设备上报多个第二小区的测量报告集，可避免频繁上报或无法上报的情况发生，提高了上报的有效性。
在一些可能的示例中，基于第一上报时长和/或第二上报时长，无人机向网络设备发送多个第二小区的测量报告集，包括：当第一上报时长内测量到多个第二小区，且第二小区的小区数等于N时，无人机向网络设备发送多个第二小区的测量报告集；或者若第一上报时长内测量到多个第二小区，且第二小区的小区数小于N，则当第一上报时长的终止时间到达时，无人机向网络设备发送多个第二小区的测量报告集。也就是说，在第一上报时长的(倒)计时期间，若测量到N个第二小区均满足事件触发条件，则立即上报这N个第二小区的测量报告集。若第一上报时长的终止时间到达时，但测量到的满足事件触发条件的第二小区的数量小于N时，上报这些满足触发条件的第二小区的测量报告集，从而可以避免N值设置过大，导致无人机长时间未上报的情况发生，可提高上报的有效性。
在一些可能的示例中，基于第一上报时长和/或第二上报时长，无人机向网络设备发送多个第二小区的测量报告集，包括：若第二上报时长内测量到多个第二小区，且第二小区的小区数大于或等于N，则当第二上报时长的终止时间到达时，无人机向网络设备发送多个第二小区的测量报告集。也就是说，在第二上报时长的计时期间，若测量到的满足事件触发条件的第二小区的数量大于或等于N，则不会立即上报这些第二小区的测量报告集。而是在第二上报时长的终止时间到达时，才上报这些第二小区的测量报告集，从而可以避免N值设置过小，导致无人机频繁上报，可提高上报的有效性。
在一些可能的示例中，测量配置还包括测量阈值，在无人机向网络设备发送第一小区的测量报告之后，还包括：当测量到多个第二小区，且多个第二小区的测量报告中的至少一个测量值大于测量阈值时，无人机向网络设备发送多个第二小区的测量报告集，第二小区均满足事件触发条件。
可以理解，在无人机上报第一个测量到的满足事件触发条件的第一小区的测量报告之后，若测量到的满足事件触发条件的第二小区的数量小于N，但是这些第二小区的测量报告中存在至少一个测量值大于测量阈值，则可以上报这些第二小区的测量报告集。在测量到的满足事件触发条件的第二小区的数量等于N之后，可以上报这N个第二小区的测量报告集。或者可以继续测量直至存在一个小区的测量值大于测量阈值，才上报这些大于或等于N个满足事件触发条件的第二小区的测量报告集。如此，可以在个别小区干扰影响通信链路的情况下，若测量到的小区的测量值大于测量阈值，则表示当前存在满足切换条件的小区，可以上报测量到的多个第二小区的测量报告集，从而可以上报可进行切换的小区的信息，可以提高网络设备决策的效率。
在一些可能的示例中，多个第二小区的测量报告集包括多个第二小区中测量值大于测量阈值的第二小区的测量报告。可以理解，无人机在飞行中可能会收到干扰，导致无人机测量到的测量值可能较小。因此，上报测量值大于测量阈值的第二小区的测量报告，从而可以上报可进行切换的小区的信息，可以提高网络设备决策的效率。
在一些可能的示例中，第二小区包括第一小区。如此，在上报第一小区的测量报告之后，可以上报包括第一小区的多个第二小区，当然还可以上报不包括第一小区的多个第二小区，从而可以提供多种上报方式，提高了上报的灵活性。
在一些可能的示例中，测量报告集包括除第一小区之外的各个第二小区的测量报告。如此，可以避免上报重复的内容，可以提高网络设备决策的效率。
在一些可能的示例中，还包括：无人机对N的大小进行调整，得到第二触发小区数。可以理解，通过调整N的大小，可以避免网络设备配置N的不合理的情况发生，利于提高上报的有效性。
在一些可能的示例中，无人机基于无人机的飞行高度和/或飞行速度，对N的大小进行调整，得到第二触发小区数包括：无人机基于无人机的飞行高度和/或飞行速度，获取N的缩放因子；无人机将N和N的缩放因子的乘积作为第二触发小区数。如此，在实际飞行过程中，通过无人机的飞行高度和/或飞行速度获取的缩放因子来调整N的大小，可提高调整N的准确率，以此避免网络设备配置的N过大或过小，利于提高上报的有效性。
在一些可能的示例中，在无人机接收网络设备的测量配置之前，当无人机的飞行高度大于高度阈值时，无人机向网络设备发送第三小区的测量报告，第三小区的测量报告包括无人机的飞行高度。可以理解，若无人机的飞行高度大于高度阈值，则表示无人机可能在网络设备的上方飞行。无人机向网络设备 发送第三小区的测量报告，可以让网络设备发送针对无人机的测量配置，以使无人机可以基于此测量配置进行上报，可以避免频繁上报，利于提高上报的有效性。
第二方面，本申请实施例公开了第二种通信方法，包括：网络设备向无人机发送测量配置，测量配置包括第一触发小区数N和事件触发条件，N大于或等于2；网络设备从无人机接收第一小区的测量报告，第一小区为接收到测量配置之后第一个满足事件触发条件的小区。如此，在无人机接收到网络设备的测量配置之后，上报第一个测量到的满足事件触发条件的小区的测量报告，提高了测量报告上报的及时性，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，网络设备从无人机接收第一小区的测量报告之后，还包括：网络设备从无人机接收N个第二小区的测量报告集，第二小区均满足事件触发条件。如此，在无人机上报第一个测量到的满足事件触发条件的第一小区的测量报告之后，再上报N个测量到的满足事件触发条件的第二小区的测量报告集，以使网络设备获取多个第二小区的测量报告集，从而网络设备可以基于测量报告集中各个第二小区的测量值决策是否进行重配置或切换，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，网络设备从无人机接收第一小区的测量报告之后，还包括：网络设备从无人机接收第一小区的删除通知，删除通知用于指示第一小区从触发小区列表中删除，触发小区列表中的小区在添加至触发小区列表时满足事件触发条件；或者网络设备从无人机接收触发小区列表中小区的测量报告。如此，可避免网络设备将无人机切换为第一小区。在触发小区列表中存在除了第一小区之外的(触发)小区时，可以上报剩余未删除的触发小区的测量报告，从而网络设备可以基于当前上报的触发小区决策是否进行重配置或切换，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，测量配置还包括第一上报时长和/或第二上报时长，第一上报时长大于第二上报时长；网络设备从无人机接收第一小区的测量报告之后，还包括：基于第一上报时长和/或第二上报时长，网络设备从无人机接收多个第二小区的测量报告集，第二小区在第二小区均满足事件触发条件。其中，第一上报时长和第二上报时长的起始时间均为确定第一小区满足事件触发条件的时间，可以理解为测量到第一小区满足触发条件之后的触发时长的终止时间。也就是说，第一上报时长和第二上报时长的计时步骤与无人机向网络设备发送第一小区的测量报告的步骤同时执行。如此，在无人机上报第一个测量到的满足事件触发条件的第一小区的测量报告之后，基于测量配置中的第一上报时长和/或第二上报时长上报多个测量到的满足事件触发条件的第二小区的测量报告集，从而可以基于测量配置中的上报时长向网络设备上报多个第二小区的测量报告集，可避免频繁上报或无法上报的情况发生，提高了上报的有效性。
在一些可能的示例中，基于第一上报时长和/或第二上报时长，网络设备从无人机接收多个第二小区的测量报告集，包括：当第一上报时长内测量到多个第二小区，且第二小区的小区数等于N时，网络设备从无人机接收多个第二小区的测量报告集；或者若第一上报时长内测量到多个第二小区，且第二小区的小区数小于N，则当第一上报时长的终止时间到达时，网络设备从无人机接收多个第二小区的测量报告集。也就是说，在第一上报时长的(倒)计时期间，若测量到N个第二小区均满足事件触发条件，则立即上报这N个第二小区的测量报告集。若第一上报时长的终止时间到达时，但测量到的满足事件触发条件的第二小区的数量小于N时，上报这些满足触发条件的第二小区的测量报告集，从而可以避免N值设置过大，导致无人机长时间未上报的情况发生，可提高上报的有效性。
在一些可能的示例中，基于第一上报时长和/或第二上报时长，网络设备从无人机接收多个第二小区的测量报告集，包括：若第二上报时长内测量到多个第二小区，且第二小区的小区数大于或等于N，则当第二上报时长的终止时间到达时，网络设备从无人机接收多个第二小区的测量报告集。也就是说，在第二上报时长的计时期间，若测量到的满足事件触发条件的第二小区的数量大于或等于N，则不会立即上报这些第二小区的测量报告集。而是在第二上报时长的终止时间到达时，才上报这些第二小区的测量报告集，从而可以避免N值设置过小，导致无人机频繁上报，可提高上报的有效性。
在一些可能的示例中，测量配置还包括测量阈值，网络设备从无人机接收第一小区的测量报告之后，还包括：当无人机测量到多个第二小区，且多个第二小区的测量报告中的至少一个测量值大于测量阈值时，网络设备从无人机接收多个第二小区的测量报告集，第二小区均满足事件触发条件。如此，在无人机上报第一个测量到的满足事件触发条件的第一小区的测量报告之后，若测量到的满足事件触发条件的 第二小区的数量小于N，但是这些第二小区的测量报告中存在至少一个测量值大于测量阈值，则可以上报这些第二小区的测量报告集。在测量到的满足事件触发条件的第二小区的数量等于N之后，可以上报这N个第二小区的测量报告集。或者可以继续测量直至存在一个小区的测量值大于测量阈值，才上报这些大于或等于N个满足事件触发条件的第二小区的测量报告集。因此，可以在个别小区干扰影响通信链路的情况下，若测量到的小区的测量值大于测量阈值，则表示当前存在满足切换条件的小区，可以上报测量到的多个第二小区的测量报告集，从而可以上报可进行切换的小区的信息，可以提高网络设备决策的效率。
在一些可能的示例中，多个第二小区的测量报告集包括多个第二小区中测量值大于测量阈值的第二小区的测量报告。可以理解，无人机在飞行中可能会收到干扰，导致无人机测量到的测量值可能较小。因此，上报测量值大于测量阈值的第二小区的测量报告，从而可以上报可进行切换的小区的信息，可以提高网络设备决策的效率。
在一些可能的示例中，第二小区包括第一小区。如此，在上报第一小区的测量报告之后，可以上报包括第一小区的多个第二小区，当然还可以上报不包括第一小区的多个第二小区，从而可以提供多种上报方式，提高了上报的灵活性。
在一些可能的示例中，测量报告集包括除第一小区之外的各个第二小区的测量报告。如此，可以避免上报重复的内容，可以提高网络设备决策的效率。
在一些可能的示例中，还包括：当无人机的飞行高度大于高度阈值时，网络设备从无人机接收第三小区的测量报告，第三小区的测量报告包括无人机的飞行高度；若飞行高度大于高度阈值，则执行向无人机发送测量配置的步骤。可以理解，若无人机的飞行高度大于高度阈值，则表示无人机可能在网络设备的上方飞行。无人机向网络设备发送第三小区的测量报告，可以让网络设备发送针对无人机的测量配置，以使无人机可以基于此测量配置进行上报，可以避免频繁上报，利于提高上报的有效性。
第三方面，本申请实施例公开了第三种通信方法，包括：网络设备从无人机接收第三小区的测量报告，第三小区的测量报告包括无人机的飞行高度；若飞行高度大于高度阈值，则网络设备向无人机发送第一测量配置。其中，第一测量配置包括第一触发小区数N和事件触发条件。可以理解，网络设备从无人机接收到第三小区的测量报告之后，若测量报告中的无人机的飞行高度大于高度阈值，则表示无人机可能在网络设备的上方飞行，可以让网络设备发送针对无人机的第一测量配置，以使无人机可以基于此第一测量配置进行上报，可以避免频繁上报，利于提高上报的有效性。
在一些可能的示例中，在网络设备从无人机接收第三小区的测量报告之前，还包括：网络设备向无人机发送测量请求。其中，测量请求用于指示上报无人机的飞行高度。此处的第三小区可以为服务小区或满足事件触发条件的小区，或者飞行高度大于高度阈值的小区，或者可测量到的小区等，在此不做限定。可以理解，在无人机接收到要求上报飞行高度的测量请求之后，上报其测量到的第三小区的测量报告和无人机的飞行高度，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，还包括：网络设备基于无人机发送测量报告的上报频率和/或上报次数，获取N的大小。可以理解，上报频率和上报次数为无人机实际使用过程中的数据，基于无人机发送测量报告的上报频率和/或上报次数获取N的大小，可提高设置N的准确率，利于提高上报的有效性。
在一些可能的示例中，还包括：网络设备向无人机发送第二测量配置；在第三上报时长内统计无人机发送测量报告的上报次数；将上报次数和第三上报时长之间的除数作为无人机发送测量报告的上报频率。其中，第二测量配置适用于终端设备，而不是专门适用于无人机的配置信息。可以理解，在无人机接收到第二测量配置之后，可以基于第二测量配置向网络设备发送触发小区的测量报告，从而网络设备可以在网络设备未设置触发小区数的情况下，基于上报次数和/或上报频率获取第一触发小区数。
在一些可能的示例中，还包括：网络设备向无人机发送第三测量配置；网络设备在第四上报时长内统计无人机发送测量报告集的上报次数；网络设备将上报次数和第四上报时长之间的除数作为无人机发送测量报告的上报频率。其中，第三测量配置适用于无人机，可以包括第三触发小区数和事件触发条件等。可以理解，在无人机接收到第三测量配置之后，可以基于第三测量配置向网络设备发送触发小区的测量报告集，从而可以在网络设备已设置触发小区数(第三触发小区数)的情况下，基于上报次数和/或上报频率调整触发小区数的大小，得到第一触发小区数。需要说明的是，第四上报时长可以与第三上 报时长相等或不等。
在一些可能的示例中，网络设备基于无人机发送测量报告的上报频率和/或上报次数，获取N的大小，包括：若上报频率小于频率阈值，则网络设备减小第三触发小区数，得到N的大小；或者若上报频率大于频率阈值，则网络设备增大第三触发小区数，得到N的大小；或者若上报次数小于上报阈值，则网络设备减小第三触发小区数，得到N的大小；或者若上报次数大于上报阈值，则网络设备增大第三触发小区数，得到N的大小。如此，基于频率阈值和/或上报阈值，与无人机上报测量报告的实际情况对第三触发小区数进行调整，得到第一触发小区数，可以提高调整的准确率，利于提高上报的有效性。
第四方面，本申请实施例公开了第四种通信方法，包括：无人机向网络设备发送第三小区的测量报告，第三小区的测量报告包括无人机的飞行高度；若飞行高度大于高度阈值，则无人机从网络设备接收第一测量配置。可以理解，无人机向网络设备发送第三小区的测量报告之后，若测量报告中的无人机的飞行高度大于高度阈值，则表示无人机可能在网络设备的上方飞行，网络设备可以向无人机发送针对无人机的第一测量配置，以使无人机可以基于此第一测量配置进行上报，可以避免频繁上报，利于提高上报的有效性。

本申请实施例的技术方案可以应用于各种通信系统，例如：第二代(second generation，2G)移动通信技术对应的全球移动通讯(global system for mobile communication，GSM)系统、介于第二代移动通信技术和第三代移动通信技术之间的通用分组无线业务(general packet radio service，GPRS)、第三代(third generation，3G)移动通信技术对应的码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统和通用移动通信系统(universal mobile telecommunication system，UMTS)、第四代(fourth generation，4G)移动通信技术对应的长期演进(long term evolution，LTE)系统、第五代(fifth generation，5G)移动通信技术对应的新空口技术(new radio，NR)系统等目前的通信系统，以及，应用于未来的通信系统，如第六代(sixth generation，6G)系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，车联网(vehicle to everything，V2X)通信，例如，车到车(vehicle to vehicle，V2V)通信、车到基础设施(vehicle to infrastructure，V2I)通信，车到行人(vehicle to pedestrian，V2P)通信，车到网络(vehicle to network，V2N)通信。
为使本申请的目的、技术方案和优点更加清楚，下面结合本申请实施例中的附图对本申请实施例进行描述。请参见图1，图1是本申请实施例提供的一种通信系统的结构示意图。如图1所示，通信系统 可以包括终端设备100和网络设备200。终端设备100可以通过有线或无线方式与网络设备200相连，还可以通过网络设备200接入到核心网中。
在本申请实施例中，网络设备200可以是用于支持终端设备100接入通信系统的设备，网络设备200可以包括接入网设备，其主要功能有：进行无线资源的管理、互联网协议(internet protocol，IP)头的压缩及用户数据流的加密、用户设备附着时进行移动管理实体(mobile management entity，MME)的选择、路由用户面数据至服务网关(service gateway，SGW)、寻呼消息的组织和发送、广播消息的组织和发送、以移动性或调度为目的的测量及测量报告的配置等等。
接入网设备可以包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，系统中的gNB，或者，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者接入网设备可以称为宿主节点、IAB宿主(IAB donor)、宿主IAB、宿主或宿主gNB(donor gNB，DgNB)等。或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(DU，distributed unit)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会转变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PDCP层信令，也可以认为是由DU发送的，或者，由DU+CU发送的。可以理解的是，接入网设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的接入网设备，也可以将CU划分为核心网CN中的接入网设备，在此不做限制。
TRP又称传输点，每个TRP具有一个或多个天线面板(panel)。多个TRP可以同时与一个终端设备100进行数据传输。终端设备100具有至少一个天线面板，通过调节天线面板的参数，能够改变该天线面板的发送波束和/或接收波束的方向。当终端设备100具有至少两个天线面板时，终端可以通过不同的天线面板同时发送或接收波束。以下描述中以基站或接入网，对网络设备200进行举例说明。
在本申请实施例中，终端设备100可以包括各种具有无线通信功能的通信设备，终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备100还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
例如，终端设备100可以包括无人机。无人机也可以称为无人飞行器(unmanned aerial vehicle，UAV)，因其灵活方便，已经越来越普及，可应用于，UAV植物保护、UAV航空拍摄、UAV森林火警监控等等。
UAV可以为旋翼型移动机器人，也可以为固定翼型移动机器人。图2以旋翼型移动机器人为例进行说明无人机的结构。如图2所示，无人机可包括动力系统、飞行控制系统和通信系统。图2中的该通信系统可以实现无人机与控制设备之间的无线通信，其中，该无线通信可以基于移动网络实现，即，无人机能够该通信系统接入移动网络，进而通过移动网络进行数据传输。
以UAV作为终端设备的通信系统还可以称为无人机系统(unmanned aerial system，UAS)。该UAS可以包括1个天线或多个天线。另外，UAS可以包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
在给定时间，UAV可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，UAS可对数据进行编码以用于传输。具体地，UAS可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
动力系统设置于无人机的机身，用于为无人机提供移动动力。动力系统可以包括电子调速器(简称为电调)、一个或多个旋翼(例如，螺旋桨)以及与为螺旋桨提供动力的电机。其中，电机连接在电子调速器与螺旋桨之间，电机和螺旋桨设置在对应的机臂上。
飞行控制系统可以包括飞行控制器和传感系统。飞行控制器用于控制UAV的飞行，例如，可以根据传感系统测量的姿态信息控制UAV的飞行。应理解，飞行控制器可以按照预先编好的程序指令对UAV进行控制，也可以通过响应来自控制设备的一个或多个控制指令对UAV进行控制。
控制设备可以位于地面端，可以通过无线方式(例如，移动网络)与UAV进行通信，用于对UAV进行远程操纵。操纵设备例如可以是遥控器或者安装有控制UAV的应用程序(application，APP)的终端设备，例如，智能手机、平板电脑等。在本申请实施例中，通过操纵设备接收用户的输入，可以指通过遥控器上的拔轮、按钮、按键、摇杆等输入装置或者终端设备上的用户界面(user interface，UI)对UAV进行操控。
应理解，上述对于无人飞行系统各组成部分的命名仅是出于标识的目的，并不应理解为对本申请实施例的限制。并且，以上列举的无人机仅为本申请的终端设备的一例，本申请并未限定于此，例如，终端设备还可以是自动驾驶汽车等。自动驾驶汽车(autonomous vehicles；self-piloting automobile)又称无人驾驶汽车、电脑驾驶汽车、或轮式移动机器人，是一种通过电脑系统实现无人驾驶的智能汽车，自动驾驶汽车依靠人工智能、视觉计算、雷达、监控装置和全球定位系统协同合作，让电脑可以在没有任何人类主动的操作下，自动安全地操作机动车辆。
或者，终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
为了便于理解，以下举例时以无人机作为终端设备，以基站作为网络设备，对本申请提供的方案进行详细说明。应理解，图1只是示意图，该通信系统中还可以包括图1未示出的其它的网络设备，例如，无线中继设备和无线回传设备。此外，本申请实施例对于通信系统中包括的核心网设备、接入网设备和终端设备的数量不做限定。如图1所示，终端设备100可以与多个网络设备进行通信。
在介绍本申请实施例提出的通信方法之前，先介绍本申请所涉及的测量事件和测量事件相关的触发时长、触发条件、触发小区、触发小区数等。测量事件可以包括适用于终端设备的A1测量事件、A2测量事件、A3测量事件、A4测量事件和A5测量事件，以及适用于无人机的H1测量事件和H2测量事件。其中，A1测量事件的触发条件为服务小区的信号质量高于阈值，可以用于关闭某些小区的测量功能。A2测量事件的触发条件为服务小区的信号质量低于阈值，通常发生之后可能会发生切换等操作，可以用于开启满足触发条件的小区的测量功能。A3测量事件的触发条件是同频/异频邻区的服务质量大于服务小区的服务质量，A3测量事件可以用于决定终端设备是否切换到邻区。A4测量事件的触发条件是异频邻区的服务质量高于阈值。A5是服务小区的服务质量低于一个阈值，且邻区的服务质量高于一个阈值。H1测量事件的触发条件是无人机的高度高于阈值，H2测量事件的触发条件是无人机的高度低于阈值。本申请对于上述的各个阈值的大小不做限定，且对于测量事件和测量事件的内容不做限定。
触发时长(time to trigger，TTT)用于衡量满足或不满足触发条件的小区是否满足事件触发条件。 例如，在测量到满足触发条件的小区A之后，无人机可以基于TTT启动计时器或定时器进行(倒)计时。若触发时长内的各个时刻该小区A均满足触发条件，则确定小区A满足事件触发条件。又例如，在测量到满足触发条件的小区A之后，无人机可以基于TTT启动计时器或定时器进行(倒)计时。若触发时长内的一些时刻满足触发条件，另一些时刻不满足触发条件，则确定小区A不满足事件触发条件。或者在测量到小区A不满足触发条件之后，无人机可以基于TTT启动计时器或定时器进行(倒)计时。若触发时长内的各个时刻该小区A均不满足触发条件，则确定小区A不满足事件触发条件。
在本申请实施例中，触发小区列表(cells trigger list)中集合了满足事件触发条件的小区，触发小区列表中的小区还可称为触发小区。也就是说，在确定小区满足事件触发条件时，还可以将确定满足事件触发条件的小区添加至触发小区列表。若触发小区列表中的(触发)小区被检测到不满足事件触发条件，可以理解为小区在测量到不满足触发条件之后的TTT内的各个时刻均不满足触发条件，则会从触发小区列表中删除该(触发)小区。
为了区分满足触发条件和不满足触发条件的TTT的两种情况，可以将测量到小区满足触发条件的时间(时刻)称为第一起始时间，将测量到小区不满足触发条件的时间(时刻)称为第二起始时间。相应地，TTT的第一终止时长为第一起始时间和TTT的时间和值，TTT的第二终止时长为第二起始时间和TTT的时间和值。例如，在12点00分00秒时测量到小区A满足触发条件，若TTT为5秒，则第一起始时间为12点00分00秒，第一终止时间为12点00分00秒+5秒，即12点00分5秒。若从12点00分00秒到12点00分5秒内的各个时刻均满足触发条件，可以在12点00分5秒将小区A添加至触发小区列表。在12点01分00秒时测量到小区A不满足触发条件，则第二起始时间为12点01分00秒，第二终止时间为12点01分00秒+5秒，即12点01分5秒。若从12点01分00秒到12点01分5秒内的各个时刻均满足触发条件，可以在12点01分5秒将小区A从触发小区列表中删除。
需要说明的是，满足触发条件和不满足触发条件的TTT可以相等或不等，且各个小区的时间长度可以相等或不等。例如，服务小区的TTT可以大于非服务小区的TTT等。
触发小区列表中的小区在满足上报条件时，会上报其中小区的测量报告。本申请对于上报条件不做限定，可以为触发小区列表中的小区数大于或等于一个阈值(例如，N等)时满足上报条件，或者可以为触发小区列表中的至少一个小区(或在不满足触发条件之后的TTT内的各个时刻均)不满足触发条件时满足上报条件，或者可以为触发小区列表中添加了第一个小区之后的时间阈值到达时满足上报条件等。
触发小区数为网络设备配置的无人机上报测量报告需要满足的(触发)小区的数量。也就是说，若触发小区数为N，则测量到N个(触发)小区在满足事件触发条件的情况下，才可以将N个小区的测量报告发送给基站。若满足事件触发条件的小区数小于N，则不会上报。
无人机在空中的通信环境与地面存在较大区别，无人机可以在基站上方飞行，与基站通过Uu口连接。由于基站都是朝向地面辐射电磁波，在空中的信号基本都是地面信号反射以及基站的波束旁瓣，导致无人机接受到的信号会比较弱。因此，无人机在空中主要以视距(line of sight，LOS)径通信为主，无人机能接收到更多的基站的信号，且会触发无人机上报更多更频繁的测量报告。
目前，长期演进(long term evolution，LTE)系统针对无人机的测量报告的上报机制进行了改进，在测量配置中增加了触发小区数N，N大于或等于2，从而可以避免每检测到一个触发小区就上报的情况。因此，当存在N个小区，且这N个小区在触发时长内均满足触发条件时，无人机向基站发送测量报告。若没有测量到N个小区在其触发时长内均满足触发条件，则不会向基站发送测量报告，从而基站不会将无人机切换到其它的小区，造成切换过晚或无人链路失败(radio link failure，RLF)的情况发生。
基于此，本申请提出一种通信方法，能够让无人机及时上报，利于提高网络设备后续决策的准确率和有效性。请参见图3，图3是本申请实施例提供的第一种通信方法的流程示意图，该方法可应用于如图1所示的通信系统中。本申请中由网络设备执行的功能也可以由网络设备中的装置(例如，芯片，或者芯片系统，或者电路)来执行，本申请中由无人机执行的功能也可以由无人机中的装置(例如，芯片，或者芯片系统，或者电路)来执行。该方法包括但不限于如下步骤S301和步骤S302，其中：
S301、网络设备向无人机发送测量配置。
相应地，无人机从网络设备接收测量配置。
在本申请实施例中，测量配置用于指示无人机何时上报测量报告，以及上报的测量报告的内容。测量配置可以包括第一触发小区数N和事件触发条件等，事件触发条件可以包括各个测量事件的触发时长和触发条件等。本申请对于测量配置的内容和形式不做限定，第一触发小区数为网络设备配置的无人机上报测量报告需要满足的(触发)小区的数量，可以参照触发小区数的描述。将第一触发小区数的大小作为N，当有N个小区满足事件触发条件的无人机时可以向网络设备发送测量报告。本申请对于N的大小不做限定，N可以为大于或等于2，N可以为网络设备预设的固定数值，还可以为网络设备和/或无人机调整之后的数值。其调整方法可以参见后面图6描述的通信方法，事件触发条件可以参照前面或后述，在此不再赘述。通过上报多于1个的小区的测量报告，可以避免单个小区逐一上报。
S302、当测量到满足事件触发条件的第一小区时，无人机向网络设备发送第一小区的测量报告。
相应地，当测量到满足事件触发条件的第一小区时，网络设备从无人机接收第一小区的测量报告。
在本申请实施例中，第一小区为无人机在接收到测量配置之后，第一个测量到的满足事件触发条件的小区。第一小区可以理解为在测量该第一小区满足测量配置之后的触发时长内的各个时刻均满足触发条件的小区。通常认为第一个测量到的小区比较重要，可以提供有效的用户数据，利于网络设备后续决策的准确率。本申请对于测量报告的内容不做限定，可以用于指示测量报告中的小区的服务质量、信号质量、信号强度等。
在图3所示的方法中，在无人机接收到网络设备的测量配置之后，上报第一个测量到的满足事件触发条件的小区的测量报告，提高了测量报告上报的及时性，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，当测量到满足事件触发条件的第一小区时，还包括：将第一小区添加至触发小区列表；将第一小区添加至触发小区列表之后，还包括：当第一小区不满足事件触发条件时，从触发小区列表中删除第一小区。
如前所述，触发小区列表中集合了满足事件触发条件的(触发)小区，可以将满足事件触发条件的(触发)小区添加至触发小区列表，还可以将不满足事件触发条件的(触发)小区从触发小区列表中删除。因此，在确定第一小区满足事件触发条件时，还可以将第一小区添加至触发小区列表。且在确定第一小区不满足事件触发条件时，还可以将第一小区从触发小区列表中删除，从而避免将不满足事件触发条件的小区的测量报告再次上报给网络设备。
在一些可能的示例中，还包括：无人机向网络设备发送第一小区的删除通知；或者无人机向网络设备发送触发小区列表中小区的测量报告。
相应地，网络设备从无人机接收第一小区的删除通知；或者网络设备从无人机接收触发小区列表中小区的测量报告。
其中，删除通知用于指示第一小区从触发小区列表中删除，或者用于指示第一小区不满足事件触发条件，或者用于指示无人机已离开第一小区的覆盖范围等。
可以理解，在触发小区列表中的第一小区被删除之后，可以向网络设备上报第一小区的删除通知，以避免网络设备将无人机切换为第一小区。在触发小区列表中存在除了第一小区之外的(触发)小区时，可以上报剩余未删除的触发小区的测量报告，从而网络设备可以基于当前上报的触发小区决策是否进行重配置或切换，利于提高网络设备后续决策的准确率和有效性。
进一步的，请参见图4，图4是本申请实施例提供的第二种通信方法的流程示意图，该通信方法可应用于如图1所示的通信系统中。如图4所示，该通信方法可以包括步骤S401至步骤S403，其中：
S401、网络设备向无人机发送测量配置。
S402、当测量到满足事件触发条件的第一小区时，无人机向网络设备发送第一小区的测量报告。
其中，步骤S401和步骤S402可参照图3的描述，在此不再赘述。
S403、无人机向网络设备发送多个第二小区的测量报告集。
相应地，网络设备从无人机接收多个第二小区的测量报告集。
其中，多个第二小区中的每一第二小区均满足事件触发条件。可以理解为各个第二小区在测量到该第二小区满足触发条件之后的触发时长内的各个时刻均满足触发条件。
本申请对于第二小区的数量不做限定，可以小于N，等于N，或者大于N。且多个第二小区可以包 括第一小区，或者可以不包括第一小区。如此，在上报第一小区的测量报告之后，可以上报不包括第一小区的多个第二小区，还可以上报包括第一小区的多个第二小区，从而可以提供多种上报方式，提高了上报的灵活性。
多个第二小区的测量报告集可以包括各个第二小区的测量报告，或者可以采用部分上报的方式，例如，上报之前未上报的内容等。在一些可能的示例中，多个第二小区的测量报告集包括除第一小区之外的各个第二小区的测量报告。如此，在多个第二小区包括第一小区的情况下，可以上报多个第二小区中除第一小区之外的各个第二小区的测量报告，从而避免上报重复的内容，可以提高网络设备决策的效率。
在一些可能的示例中，多个第二小区的测量报告集包括多个第二小区中测量值大于测量阈值的第二小区的测量报告。其中，测量值可以包括服务质量、信号质量、信号强度等，本申请对于测量阈值的大小不做限定，可以为A4测量事件的阈值。测量阈值可以携带与测量配置中，适用于小区干扰的情况下。可以理解，无人机在飞行中可能会收到干扰，导致无人机测量到的测量值可能较小。因此，上报测量值大于测量阈值的第二小区的测量报告，从而可以上报可进行切换的小区的信息，可以提高网络设备决策的效率。
本申请对于上报多个第二小区的情况不做限定，可以包括以下3种情况进行限制，其中：
情况一、无人机向网络设备发送N个第二小区的测量报告集。
相应地，网络设备从无人机接收N个第二小区的测量报告集。
可以理解，在无人机上报第一个测量到的满足事件触发条件的第一小区的测量报告之后，再上报N个测量到的均满足事件触发条件的第二小区的测量报告集，以使网络设备获取多个第二小区的测量报告集，从而网络设备可以基于测量报告集中各个第二小区的测量值决策是否进行重配置或切换，利于提高网络设备后续决策的准确率和有效性。
情况二、基于第一上报时长和/第二上报时长，无人机向网络设备发送多个第二小区的测量报告集。
相应地，基于第一上报时长和/第二上报时长，网络设备从无人机接收多个第二小区的测量报告集。
本申请对于第一上报时长和第二上报时长的大小不做限定，可以如图5所示，第一上报时长大于第二上报时长。第一上报时长和/或第二上报时长携带于测量配置中，用于指示第一小区之后的多个第二小区的测量报告集的上报时间。第一上报时长和第二上报时长的起始时间均为确定第一小区满足事件触发条件的时间，可以理解为测量到第一小区满足触发条件之后的触发时长的终止时间。也就是说，第一上报时长和第二上报时长的计时步骤与无人机向网络设备发送第一小区的测量报告的步骤同时执行。无人机可以采用定时器或计时器等进行(倒)计时，在此不做限定。第一上报时长的终止时长为第一上报时长的起始时间和第一上报时长的时间和值，第二上报时长的起始时间和第二上报时长的时间和值。以第一上报时长为1分钟，第二上报时长为30秒为例，若确定第一小区满足事件触发条件的时间(第一小区的触发时长的第一终止时间)为12点2分00秒，则第一上报时长的起始时间和第二上报时长的起始时间为12点2分00秒，第一上报时长的终止时间为12点3分00秒，第二上报时长的终止时间为12点2分30秒。
在一些可能的示例中，步骤S403可以包括：当第一上报时长内测量到多个第二小区，且第二小区的小区数等于N时，向网络设备发送多个第二小区的测量报告集；或者若第一上报时长内测量到多个第二小区，且第二小区的小区数小于N，则当第一上报时长的终止时间到达时，向网络设备发送多个第二小区的测量报告集。也就是说，在第一上报时长的(倒)计时期间，若测量到N个第二小区均满足事件触发条件，则立即上报这N个第二小区的测量报告集。若第一上报时长的终止时间到达时，但测量到的满足事件触发条件的第二小区的数量小于N时，上报这些满足触发条件的第二小区的测量报告集，从而可以避免N值设置过大，导致无人机长时间未上报的情况发生，可提高上报的有效性。
在一些可能的示例中，步骤S403可以包括：若第二上报时长内测量到多个第二小区，且第二小区的小区数大于或等于N，则当第二上报时长的终止时间到达时，向网络设备发送多个第二小区的测量报告集。也就是说，在第二上报时长的计时期间，若测量到的满足事件触发条件的第二小区的数量大于或等于N，则不会立即上报这些第二小区的测量报告集。而是在第二上报时长的终止时间到达时，才上报这些第二小区的测量报告集，从而可以避免N值设置过小，导致无人机频繁上报，可提高上报的有效性。
需要说明的是，以上两个示例可以单独或结合起来使用。
可以理解，在无人机上报第一个测量到满足事件触发条件的第一小区的测量报告之后，基于测量配置中的第一上报时长和/或第二上报时长上报多个测量到的满足事件触发条件的第二小区的测量报告集，从而可以基于测量配置中的上报时长向网络设备上报多个第二小区的测量报告集，可避免频繁上报或无法上报的情况发生，提高了上报的有效性。
情况三、当测量到多个第二小区，且多个第二小区的测量报告中的至少一个测量值大于测量阈值时，无人机向网络设备发送多个第二小区的测量报告集。
相应地，当测量到多个第二小区，且多个第二小区的测量报告中的至少一个测量值大于测量阈值时，网络设备从无人机接收多个第二小区的测量报告集。
可以理解，在无人机上报第一个测量到在满足事件触发条件的第一小区的测量报告之后，若测量到的满足事件触发条件的第二小区的数量小于N，但是这些第二小区的测量报告中存在至少一个测量值大于测量阈值，则可以上报这些第二小区的测量报告集。在测量到的满足事件触发条件的第二小区的数量等于N之后，可以上报这N个第二小区的测量报告集。或者可以继续测量直至存在一个小区的测量值大于测量阈值，才上报这些测量到的这些大于或等于N个满足事件触发条件的第二小区的测量报告集。如此，可以在个别小区干扰影响通信链路的情况下，若测量到的小区的测量值大于测量阈值，则表示当前存在满足切换条件的小区，可以上报测量到的多个第二小区的测量报告集，从而可以上报可进行切换的小区的信息，可以提高网络设备决策的效率。
需要说明的是，本申请以上述的3种情况进行示例，但不限于这3种情况向网络设备发送多个第二小区的测量报告集，且这3种情况可以单独或结合起来使用。
在图4所示的通信方法中，在无人机上报第一个测量到的满足事件触发条件的第一小区的测量报告之后，向网络设备上报多个第二小区的测量报告集，从而网络设备可以基于测量报告集中各个第二小区的测量值决策是否进行重配置或切换，利于提高网络设备后续决策的准确率和有效性。
在一些可能的示例中，在步骤S401之后，还包括：无人机对N的大小进行调整，得到第二触发小区数。可以理解，通过调整N的大小，可以避免网络设备配置N的不合理的情况发生，利于提高上报的有效性。
本申请对于调整N的方法不做限定，可以基于测量到的第二小区的数量和N的大小进行调整，例如，第二小区的数量大于N，则将N值调大；第二小区的数量小于N，则将N值调小等。或者在一些可能的示例中，无人机对N的大小进行调整，得到第二触发小区数可以包括：基于无人机的飞行高度和/或飞行速度，对N的大小进行调整，得到第二触发小区数。
其中，飞行高度越高和/或飞行速度越快，可以减小N的大小，或者可以增大N的大小。或者在一些可能的示例中，可以基于无人机的飞行高度和/或飞行速度获取N的缩放因子；将N和N的缩放因子的乘积作为第二触发小区数。
其中，缩放因子可以等于飞行高度(height)和飞行速度(speed)的和值的倒数，如1/(height+speed)。缩放因子还可以为飞行高度的倒数和/或飞行速度的倒数之间的和值等，在此不做限定。如此，在实际飞行过程中，通过无人机的飞行高度和/或飞行速度获取的缩放因子来调整N的大小，可提高调整N的准确率，以此避免网络设备配置的N过大或过小，利于提高上报的有效性。
在一些可能的示例中，还包括：当无人机的飞行高度大于高度阈值时，从无人机接收第三小区的测量报告，第三小区的测量报告包括无人机的飞行高度；若飞行高度大于高度阈值，则执行向无人机发送测量配置的步骤。
可以理解，若无人机的飞行高度大于高度阈值，则表示无人机可能在网络设备的上方飞行。无人机向网络设备发送第三小区的测量报告，可以让网络设备发送针对无人机的测量配置，以使无人机可以基于此测量配置进行上报，可以避免频繁上报，利于提高上报的有效性。
请参见图6，图6是本申请实施例提供的第三种通信方法的流程示意图，该通信方法可应用于如图1所示的通信系统中。如图6所示，该通信方法可以包括步骤S601和步骤S602，其中：
S601、无人机向网络设备发送第三小区的测量报告。
相应地，网络设备从无人机接收第三小区的测量报告。
其中，第三小区可以为满足其他的测量事件的触发条件的小区，或者无人机的飞行高度大于高度阈 值的任一小区。例如，在一些可能的示例中，在步骤S601之前，还包括：无人机确定无人机的飞行高度大于高度阈值。本申请对于高度阈值不做限定，可以为H1测量事件的阈值或其他阈值等。可以理解，若无人机的飞行高度大于高度阈值，则表示无人机可能在网络设备的上方飞行。无人机向网络设备发送第三小区的测量报告，可以让网络设备发送针对无人机的测量配置，以使无人机可以基于此测量配置进行上报，可以避免频繁上报，利于提高上报的有效性。
或者在一些可能的示例中，在步骤S601之前，还包括：网络设备向无人机发送测量请求。
相应地，无人机从网络设备接收第三小区的测量报告。
在本申请实施例中，第三小区的测量报告可以包括无人机的飞行高度。测量请求用于指示上报无人机的飞行高度，此处的第三小区可以为服务小区或在其触发时长内满足触发条件的小区，或者飞行高度大于高度阈值的小区，或者可测量到的小区等，在此不做限定。可以理解，在无人机接收到要求上报飞行高度的测量请求之后，上报其测量到的第三小区的测量报告和无人机的飞行高度，利于提高网络设备后续决策的准确率和有效性。
S602、若第三小区的飞行高度大于高度阈值，则网络设备向无人机发送第一测量配置。
相应地，若第三小区的飞行高度大于高度阈值，则无人机从网络设备接收第一测量配置。
其中，第一测量配置可以参照图3和图4中描述的测量配置，包括第一触发小区数N和事件触发条件等，在此不再赘述。第一测量配置可以为适用于无人机的测量配置或者可以为与无人机的飞行高度相关的测量配置。
在图6所示的通信方法中，网络设备从无人机接收到第三小区的测量报告之后，若测量报告中的无人机的飞行高度大于高度阈值，则表示无人机可能在网络设备的上方飞行，可以让网络设备发送针对无人机的第一测量配置，以使无人机可以基于此第一测量配置进行上报，可以避免频繁上报，利于提高上报的有效性。
本申请对于网络设备获取第一测量配置中的N值的大小的方法不做限定，可以基于无人机的飞行高度进行确定，或者可以基于无人机的飞行速度进行确定，或者在一些可能的示例中，可以包括：基于无人机发送测量报告的上报频率和/或上报次数获取N的大小。可以理解，上报频率和上报次数为无人机实际使用过程中的数据，基于无人机发送测量报告的上报频率和/或上报次数获取N的大小，可提高设置N的准确率，利于提高上报的有效性。
本申请对于获取无人机发送测量报告的上报频率和/或上报次数的方法不做限定，可以通过步骤S601之前未设置触发小区数的方式一和/或通过步骤S601之前已设置触发小区数的方式二进行获取。
方式一、网络设备向无人机发送第二测量配置；在第三上报时长内统计无人机发送测量报告的上报次数；将该上报次数和第三上报时长之间的除数作为无人机发送测量报告的上报频率。
相应地，无人机从网络设备接收第二测量配置。
其中，第二测量配置适用于终端设备，而不是专门适用于无人机的配置信息。第二测量配置可以包括前述的A1测量事件、A2测量事件、A3测量事件、A4测量事件和A5测量事件对应的内容。第三上报时长为网络设备配置的一个时长，用于衡量无人机发送测量报告的上报频率和/或上报次数。该第三上报时长的起始时间可以为网络设备发送第二测量配置之后无人机第一个上报的测量报告的接收时间。也就是说，第三上报时长的起始时间可以为无人机接收到第二测量配置之后，向网络设备发送的第一个小区的测量报告的时间。然后，网络设备在接收到无人机上报的第一个小区的测量报告时开始(倒)计时，统计第三上报时长内无人机向网络设备上报测量报告的上报次数，从而可将该上报次数和第三上报时长之间的除数作为无人机发送测量报告的上报频率。如此，可以在网络设备未设置触发小区数的情况下，基于上报次数和/或上报频率获取N的大小。
方式二、网络设备向无人机发送第三测量配置；在第四上报时长内统计无人机发送测量报告集的上报次数；将该上报次数和第四上报时长之间的除数作为无人机发送测量报告的上报频率。
相应地，无人机从网络设备接收第三测量配置。
其中，第三测量配置适用于无人机，可以包括第三触发小区数和事件触发条件等。事件触发条件可参照前述，例如，第一测量配置中的描述，在此不再赘述。第三触发小区数为在步骤S601之前网络设备已配置的触发小区数，第一触发小区数可以理解为第三触发小区数经过调整之后得到的数值。第四上 报时长为网络设备配置的一个时长，用于衡量无人机发送测量报告的上报频率和/或上报次数。该第四上报时长的起始时间可以为无人机接收到第三测量配置之后，向网络设备发送的第一个小区的测量报告的时间。然后，网络设备在接收到无人机上报的第一个小区的测量报告时开始(倒)计时，统计第四上报时长内无人机向网络设备上报测量报告集的上报次数，从而可将该上报次数和第四上报时长之间的除数作为无人机发送测量报告的上报频率。如此，可以在网络设备已设置触发小区数(第三触发小区数)的情况下，基于上报次数和/或上报频率调整触发小区数的大小，得到第一触发小区数。
需要说明的是，方式一中统计的是小区的测量报告的数据，方式二参照第一测量配置的上报方式，统计的是小区的测量报告集的数据，每一次上报的测量报告集中小区的数量可以为1个或多个。第四上报时长可以与第三上报时长相等或不等。
在一些可能的示例中，基于无人机发送测量报告的上报频率和/或上报次数，获取N的大小，包括：若上报频率小于频率阈值，则减小第三触发小区数，得到N的大小；或者若上报频率大于频率阈值，则增大第三触发小区数，得到N的大小；或者若上报次数小于上报阈值，则减小第三触发小区数，得到N的大小；或者若上报次数大于上报阈值，则增大第三触发小区数，得到N的大小。
本申请对于频率阈值或上报阈值不做限定，对于减小和增大第三触发小区数的限度不做限定，可以减1或加1或其他数值，或者可以减小一半或增大一半等。如此，基于频率阈值和/或上报阈值，与无人机上报测量报告的实际情况对第三触发小区数进行调整，得到第一触发小区数，可以提高调整的准确率，利于提高上报的有效性。
