本申请实施例中的接入网设备(本申请中有时也被称为网络设备或无线接入网设备)可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信***中的下一代基站(next generation NodeB，gNB)、6G移动通信***中的下一代基站、未来移动通信***中的基站或WiFi***中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。无线接入网设备可以是宏基站，也可以是微基站或室内站，还可以是中继节点或施主节点等。可以理解，本申请中的无线接入网设备的全部或部分功能也可以通过在硬件上运行的软件功能来实现，或者通过平台(例如云平台)上实例化的虚拟化功能来实现。本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。为了便于描述，下文以基站作为无线接入网设备为例进行描述。
本申请实施例中的无人机也可称为终端设备，终端设备也可以称为终端、用户设备(user equipment，UE)、移动台、移动终端等。终端可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IoT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端所采用的具体技术和具体设备形态不做限定。为了便于描述，下文以终端为无人机为例进行描述。

在本申请的实施例中，UTM为在网络侧引入的一个对无人机业务进行管理的网元，一种可能的实现中，该网元可以为核心网网元(例如为设置在核心网的功能实体)或者为独立的控制网元。UTM节点也可以称为UTM模块或者UTM网元或者UTM实体等。
另外为便于理解本申请的技术方案，对与UAV管理相关术语进行介绍。
UAV标识。一种可能的实现方式中，为了更好的管理UAV，提出了对UAV的标识需求，例如采取远端标识(remote identity，remote ID)标识UAV。remote ID是UAV在飞行中提供 给其他设备或控制平台用于接收或确定该UAV的身份和/或位置信息的信息。当UAV似乎以不安全的方式飞行或不应被允许飞行时，remote ID可以用于帮助识别该UAV或用于帮助找到控制该UAV的控制平台或控制站。remote ID为更复杂的UAV操作所需的安全要求奠定了基础。容易理解的，remote ID也可以是其它能够实现对UAV进行标识的信息，例如其他用于标识UAV身份信息的信息，本申请以该标识为remote ID为例进行介绍。
跟踪区(tracking area，TA)。TA是通信***为终端的位置管理设立的概念。其被定义为终端不需要更新服务的自由移动区域。TA功能为实现对终端位置的管理，可分为寻呼管理和位置更新管理。终端通过跟踪区注册告知核心网该终端的跟踪区。一般的，TA是小区级的配置，多个小区可以配置相同的TA，且一个小区只能属于一个TA。跟踪区标识(tracking area identity，TAI)是每个TA区别于其他TA的标识，TAI可以是由公用陆地移动通信(Public Land Mobile Network，PLMN)和跟踪区代码(tracking area code，TAC)组成，即TAI＝PLMN+TAC。多个TA组成一个TA列表(TA List)，同时分配给一个终端，终端在该TA列表内移动时不需要执行跟踪区更新(tracking area update，TAU)，以减少与网络设备的频繁交互；当终端进入不在其所注册的TA列表中的TA区域时，需要执行TAU，一般的，核心网给终端重新分配一组TA，新分配的TA也可包含原有TA列表中的一些TA；除了这种情况，终端还会定期做TAU，让核心网知道该终端的位置。
基于接入网设备的通知区(radio access network based notification area，RNA)。RNA的组成主要有两种，一种RNA的组成是小区列表，另一种RNA的组成是TAC标识或跟踪区域码标识。终端在进入去激活(INACTIVE)态之前的最后服务基站会给终端配置RNA，意味着当终端在RNA范围内移动的时候，不需要做RNA更新(RNA update，RNAU)。如果终端出了RNA，就会发起RNAU，除此之外，也会定期做TAU，让最后服务基站知道终端的位置。
***信息(system information，SI)是小区发给终端的消息，NR***中，分为最小***信息(minimum system information，MSI)和其他***信息(other system information，OSI)，其中最小***信息包括主信息块(master information block，MIB)和***消息块1(system information block 1，SIB1)，周期发送。其中SIB1又可以称为剩余最小***消息(remaining minimum SI，RMSI)，MSI一般包括包含小区选择和初始接入信息的***消息和其他SI的调度信息，除MIB和SIB1以外的全部***消息可以称为OSI，而OSI在SystemInformation消息(SIB2及以上)中传输，为了基站省电所以不是周期发送，而是基于请求发送。
在一些特殊情况下、特殊时段可以对特定区域采取限制飞行的管制措施，而UAV如何知道哪些区域是特定区域，以及UAV在知道特定区域后在空口上可能会有哪些行为目前都需要进行研究。为了方便管理UAV，UAV可以广播其remote ID，但UAV一直广播remote ID会产生较大的能耗,为了提升管理UAV的性能，本申请实施例提供了一种无人机的通信方法300，如图3所示，包括：
可选步骤S310：第一通信设备向无人机发送第一指示信息。
相应的，无人机接收来自第一通信设备的第一指示信息。
容易理解的，本申请实施例中不限定第一通信设备向无人机发送第一指示信息的时机或触发条件。
例如，当该第一通信设备确定无人机在第一区域内时，该第一通信设备向无人机发送第一指示信息用于指示无人机开始广播第一标识。示例性的，还包括第一通信设备确定第一区域，其中，在第一区域中的无人机需要广播第一消息，第一消息包括第一标识，第一标识用 于指示无人机的身份信息。
其中，第一标识用于向接收端的设备指示该UAV的身份信息。可选的，该第一标识可以是remote ID。可选的，该第一标识具有多种可能的确定或分配方式。例如，UAV由UAS服务提供商(UAS service supplier，USS)提供remote ID；或者，UAV在开机/飞行过程中向UTM注册，由UTM分配，remote ID在每次飞行时可变；再例如，存储在UAV中，由制造商分配等。
再例如，第一通信设备接收到其他网元或平台的消息后，第一通信设备向无人机发送第一指示信息。示例性的，无人机管理平台或核心网设备向第一通信设备发送指示信息，该指示信息用于指示该无人机需要广播第一标识，或者该指示信息用于指示无人机需要广播第一标识的区域(也可称为特定区域)信息。一种可能的方式为通过操作、管理和维护(operation,administration and maintenance，OAM)或者AMF或者UTM来将特定区域的信息配置给第一通信设备。即第一通信设备接收来自第一核心网设备的配置信息，配置信息用于指示第二区域，第二区域为特定区域(即在该特定区域内的无人机需要广播第一标识)，或第二区域为普通区域(即在该区域内的无人机不需要广播第一标识)。例如，第一通信设备确定无人机处于特定区域时，向无人机发送第一指示信息。
一种可能的方式中，第一指示信息用于指示无人机广播第一消息。例如，该第一指示信息可以为比特信息，示例性的，该第一指示信息为1比特，第一指示信息为“1”时，该第一指示信息用于指示无人机广播第一消息，当第一指示信息为“0”时，该第一指示信息用于指示无人机不需要广播第一消息。当然，第一指示信息也可以有其他实现方式用于指示无人机广播第一消息。例如，第一指示信息包含指示该无人机处于管控区域的信息，或者第一指示信息包含指示该无人机需要表明身份信息的信息。本申请实施例并不限定。
又一种可能的方式中，该第一指示信息用于指示第一区域(也可称为第一区域信息)。容易理解的，第一指示信息用于指示第一区域可以理解为，第一指示信息用于指示在第一区域内的UAV需要广播该UAV的身份信息。或者，第一指示信息用于指示第一区域为特定区域，其中，特定区域指的是在该区域内UAV需要广播身份信息。可选的，特定区域可以是预定义或预配置的。
可选的，第一区域信息包括位置信息、小区信息、跟踪区域信息和接入网设备的通知区域信息中的一种或多种。也就是说，可以使用第一指示信息指示第一区域的范围。容易理解的，第一区域信息也可以是新引入或新定义的区域信息。例如，新定义限定区域，采用新的区域划分方式。
其中，位置信息也可以称为区域信息，可以通过包括经度、维度和高度表示。或者位置信息也可以是地理位置信息，例如上海市浦东新区XX街道。
小区信息可以通过小区标识表示。例如，第一指示信息指示了组成第一区域的小区列表。
高度信息可以是相对于地面的高度，或者，是相对于海平面的高度(海拔高度)，或者，是相对于某个参考点的高度(相对高度)。
时间信息可以是绝对时间信息或相对时间信息，例如，时间信息用于指示UAV在第一区域内时需要广播第一消息的时间段。
跟踪区域信息或接入网设备的通知区域信息可以与第一区域对应。例如，可以指表明与第一区域对应的TA或RNA，处于这些TA或RNA中的UAV需要广播第一消息。
可以理解的，在第一指示信息中也可以通过其他信息来指示第一区域，例如，采取参考坐标的方式来表征第一区域，只要能指示出第一区域即可，本申请实施例对此不做限定。
示例性的，在***信息中携带第一指示信息，用于指示第一区域。第一区域可以由小区信息或区域信息(zone)或TA或RNA来表示。其中，第一通信设备(例如gNB)可以在***信息中增加小区是否是特定区域的指示。例如，gNB可以在***信息MIB中增加表示小区是否为特定区域的指示信息，若指示信息为true或1，则表明该无人机接入的小区为特定区域，否则若指示信息为false或0或者MIB中不包括该指示信息，则表明该小区不为特定区域。区域信息zone可以由具体的地理信息如经纬度来表示，可选的还可以包含对应位置的高度信息。TA/RNA可以与特定区域对应。如可在***信息中表明哪(几)个TA/RNA与特定区域对应，处于这些TA/RNA中的小区要求UAV在PC5口上广播Remote ID。
S320:无人机根据第一指示信息确定广播第一消息，第一消息包括第一标识，第一标识用于指示无人机的身份信息。
一种可能的无人机根据第一指示信息确定广播第一消息的方式中，无人机根据第一指示信息确定广播第一消息。例如该第一指示信息为1比特，第一指示信息为“1”时，该第一指示信息用于指示无人机广播第一消息。
又一种可能的无人机根据第一指示信息确定广播第一消息的方式中，无人机根据第一指示信息和来自其他网元或平台的信息，和/或，来自无人机内部的信息确定广播第一消息。也就是说，无人机可以根据第一指示信息，无人机内部的信息和来自其他网元或平台的信息中的一种或多种确定广播第一消息。
其中，无人机内部的信息可以包括无人机的位置信息，无人机的飞行路线信息，飞行权限信息等，例如，无人机根据无人机内部的信息确定该无人机需要广播第一消息或者不需要广播第一消息。示例性的，无人机确定自身位置处于第一指示信息指示的第一区域内，该第一区域为限制区域，无人机确定需要广播第一消息。
示例性的，来自其他网元或平台的信息可以包括，用于指示第二区域信息的信息。其中，第二区域信息可以是需要广播第一消息的区域(例如采取白名单指示该区域)或者是不需要广播第一消息的区域(例如采取黑名单指示该区域)。例如，第二区域信息可以是白名单或黑名单，示例性的，在白名单对应的区域内的无人机不需要广播第一消息，在黑名单对应的区域内的无人机需要广播第一消息。其他网元或平台可以是核心网设备或无人机控制平台或无人机控制器，或其他与无人机可以交互的网元或平台，或者为其他无人机。
容易理解的，无人机有多种可能的方式，获取来自其他网元或平台的信息，本申请实施例以其他网元或平台为核心网设备为例进行介绍。
一种可能的方式中，该方法300还包括S330：无人机接收来自第一核心网设备的第二指示信息，第二指示信息用于指示第二区域信息。
其中，可选的，步骤S320中的无人机根据第一指示信息确定广播第一消息包括：无人机根据第一指示信息和第二指示信息确定广播第一消息。
一种可能的方式中，第二区域信息包括位置信息、小区信息、跟踪区域信息和接入网设备的通知区域信息中的一种或多种。关于位置信息、小区信息、跟踪区域信息和接入网设备的通知区域信息的相关介绍可以参考第一区域信息的相关介绍，不再赘述。容易理解的，第二区域信息也可以是新引入或新定义的区域信息。例如，新定义限定区域，采用新的区域划分方式。例如，第二区域信息还有可能是一种新定义的区域信息，需要预先由核心网/第三方平台定义第二区域信息与第一通信设备(例如基站)之间的对应关系，通过OAM方式配置给第一通信设备。
示例性的，无人机根据第一指示信息和第二指示信息确定广播第一消息包括：
第一指示信息指示第一区域，例如第一指示信息指示无人机当前接入的小区，第二指示信息指示第二区域，例如，第二指示信息指示黑名单，无人机根据当前接入的小区处于黑名单或者确定当前接入的小区需要广播标识信息确定广播第一消息。本申请实施例并不限定，无人机根据第一指示信息，第二指示信息和无人机内部的信息中的一种或多种确定广播第一消息的方式，也就是说，可以交给无人机内部实现，当无人机根据第一指示信息，第二指示信息和无人机内部的信息中的一种或多种确定无人机需要广播第一消息时，无人机则确定广播第一消息。其中，无人机需要广播第一消息可以包括无人机确定当前处于管控区域。
示例性的，本申请给出无人机收到第一指示信息后的几种可能的实现方式，
当无人机进行小区选择/重选/切换到服务小区，读取到服务小区***信息时，
如果第一指示信息指示服务小区为特定区域，则UAV广播第一消息，例如在PC5口上开启广播第一标识。
或如果第一指示信息指示了特定区域的Zone，UAV先确定自己的位置，确定自己当前位置是否在该Zone内，如果是，则UAV广播第一消息。
或如果第一指示信息指示服务小区为特定区域TA/RNA中指示的小区，则UAV在广播第一消息。
再例如，第一指示信息指示了第一区域(例如无人机的服务小区)，来自核心网设备第二指示信息指示了需要广播第一消息的第二区域(例如，需要广播第一消息的小区列表)，无人机根据第一区域在第二区域内(例如，无人机的服务小区包含在需要广播第一消息的小区列表内)，无人机确定广播第一消息。容易理解的，仅是以小区信息为例，小区信息还可以换成其他区域信息，例如小区信息替换成位置信息，无人机根据当前位置包含在需要广播第一消息的位置区域内确定广播第一消息。也就是说，无人机从核心网收第二区域信息，从第一网络设备接收第一区域信息，如果第一区域属于或不属于从核心网收到的第二区域信息，则无人机开启广播第一消息。
容易理解的，以上无人机收到第一指示信息和/或第二指示信息后的几种可能的实现方式仅为示例，不限定还有其他根据第一指示信息，第二指示信息和无人机内部的信息中的一种或多种确定无人机需要广播第一消息的方式。
一种可能的方式中，无人机根据第一指示信息确定广播第一消息包括：
无人机根据第一指示信息确定在第一区域内广播第一消息，第一区域为特定区域。容易理解的，本申请实施例中的特定区域可以理解为管控区域，特殊区域或限制区域等。
一种可能的方式中，第一消息还包括：位置信息和飞行路线信息中的一种或多种。也就是说，UAV可在PC5口上广播Remote ID，还可以广播其当前的位置和高度信息、当前的飞行速度、飞行路线等信息用于监管。
一种可能的方式中，第一标识是预定义、预配置或动态分配的。可选的，第一标识为远端标识remote ID。当然，第一标识还可以是其他能够标识该无人机的信息，本申请实施例并不限定。
一种可能的方式中，无人机广播第一消息包括：在第一接口上广播第一消息，第一接口为PC5接口。或者，无人机通过WiFi广播第一消息，本申请实施例并不限定。示例性的，PC5口广播专用的目的地ID(DST ID)用于地面监管***，通过上层信令如PC5-S消息来承载Remote ID等信息；可选的，还可以为UAV引入新的上层协议层，该协议层用于承载UAV的广播信息内容；还可以以应用数据的方式来承载Remote ID等信息，通过PC5口广播。可选的，无人机广播第一消息包括：对第一消息采用公密钥或私密钥进行加密。一种可能的方 式中，第一指示信息携带在非接入层消息中。
可选的，UAV还可以基于监听到的小区***信息进行判断，而不受限于服务小区，如下图2所示。当前UAV处于cell1与cell2的服务范围内，服务UAV的小区为cell1，cell1不在特定区域内，而cell2在特定区域内。当无人机读取到cell2的***信息表明cell2处于特定区域内，虽然此时cell2没有为UAV提供服务，为了安全起见，UAV此时可以开启PC5上的广播。另外，考虑到UAV功耗问题，可以在UAV侧预配置一个门限值，该门限值可以为参考信号接收功率(Reference signal received power，RSRP)和参考信号接收质量(Reference signal received quality，RSRQ)中的一种或多种，当接收到***信息大于该门限值时，再开启PC5口上的广播。
可选的，方法300还包括：根据第一标识对该无人机进行管理。
例如，第一通信设备根据第一标识对该无人机进行管理。或者，当地面监管***接收到UAV的PC5广播后，可以与UTM等***进行通信，进而找到UAV的控制器或者通过UTM等***来给UAV下达指令，对于指示UAV后续可能的行为有：强制UAV降落、监管***接管UAV、给UAV下发新的飞行路径指示UAV后续飞行等。
也就是说，可以是第一通信设备、第一核心网设备，地面监管***或UAV的控制器中的一种或多种对无人机进行管理，本申请以第一通信设备进行管理进行举例。
示例性的，第一通信设备向无人机发送第三指示信息，所述第三指示信息包括用于指示强制降落信息、监管***监管信息和更新的飞行路径信息中的一种或多种。相应的，无人机接收来自第一通信设备的第三指示信息。
通过该方法，使得无人机根据第一指示信息，无人机内部的信息和来自其他网元或平台的信息中的一种或多种确定广播Remote ID等信息，在满足监管的同时避免消耗过多资源。
