本申请涉及通信技术领域，特别涉及一种通信方法、装置、设备及存储介质。The present application relates to the field of communication technology, and in particular to a communication method, apparatus, device and storage medium.
空中通信可以使得用户在诸如飞机之类的飞行设备上进行通信业务，所以，如何实现空中通信成为当前研究的热点。由于基于卫星实现空中通信存在费用高、容量小、难以普及等缺陷，所以，当前提出了基于地面的接入网设备(如基站)实现空中通信，譬如，如图1所示，可以通过多个接入网设备来实现连续覆盖，从而保证空中通信的连续性。Air communication allows users to communicate on flying equipment such as airplanes, so how to achieve air communication has become a hot topic of current research. Since satellite-based air communication has the disadvantages of high cost, small capacity, and difficulty in popularization, it is currently proposed to achieve air communication based on ground access network equipment (such as base stations). For example, as shown in Figure 1, continuous coverage can be achieved through multiple access network equipment, thereby ensuring the continuity of air communication.
然而，不同飞行设备在空中飞行的高度是不相同的，如此以来，对于飞行高度较高的飞行设备来说在其经过的参考平面上的小区可能出现较大范围的重叠区域，如图1所示，对于飞行设备2来说，其经过的参考平面上的小区a和小区b存在较大范围的重叠区域。若飞行设备经过重叠区域，如果两个接入网设备采用同频组网方式，容易造成同频干扰，从而影响空中通信质量。However, different flying devices fly at different altitudes in the air. Therefore, for flying devices with higher altitudes, the cells on the reference plane they pass through may have a large overlapping area. As shown in Figure 1, for flying device 2, cells a and b on the reference plane it passes through have a large overlapping area. If the flying device passes through the overlapping area, if the two access network devices use the same frequency networking mode, it is easy to cause same frequency interference, thereby affecting the quality of air communication.

在对本申请实施例提供的通信方法进行详细介绍之前，先对本申请实施例涉及的实施环境进行简单介绍。Before introducing the communication method provided in the embodiment of the present application in detail, a brief introduction to the implementation environment involved in the embodiment of the present application is first given.
请参考图2，该图2是根据一示例性实施例提供的实施环境的示意图。该实施环境中包括第一接入网设备210、第二接入网设备220和飞行设备230。其中，该飞行设备230可以与第一接入网设备210建立通信连接，也可以与该第二接入网设备220建立通信连接。Please refer to Figure 2, which is a schematic diagram of an implementation environment provided according to an exemplary embodiment.

In some embodiments, the first access network device 210 may be called a base station or a ground base station.
同理，该第二接入网设备220发射的信号的方向也是朝向空中的，以便于能够为飞行设备230提供空中通信服务。在一些实施例中，该第二接入网设备220也可以称为基站或地面基站。Similarly, the direction of the signal transmitted by the second access network device 220 is also toward the air, so as to provide air communication services for the flying device 230. In some embodiments, the second access network device 220 may also be referred to as a base station or a ground base station.
其中，该飞行设备230包括但不限于飞机之类的配置有通信装置的设备。该飞行设备230的数量可以为一个，或者，该飞行设备230的数量也可以为多个。The flying device 230 includes but is not limited to a device such as an airplane equipped with a communication device. The number of the flying device 230 may be one, or the number of the flying device 230 may also be multiple.
进一步地，该实施环境中还可能包括第三接入网设备，该第三接入网设备的通信方式与第一接入网设备210、第二接入网设备220的通信方式相同或类似。在一些实施例中，该第三接入网设备可以为第一接入网设备210或第二接入网设备220，或者，该第三接入网设备也可以为与第一接入网设备210和第二接入网设备220均不同的其他接入网设备。Furthermore, the implementation environment may also include a third access network device, and the communication mode of the third access network device is the same as or similar to the communication mode of the first access network device 210 and the second access network device 220.

在一些实施例中，该第一接入网设备210的数量可以为一个或者多个，该第一接入网设备210的数量可以为一个或者多个。In some embodiments, the number of the first access network devices 210 may be one or more, and the number of the first access network devices 210 may be one or more.
在介绍完本申请实施例涉及的实施环境后，接下来将结合附图对本申请提供的通信方法进行详细介绍。After introducing the implementation environment involved in the embodiments of the present application, the communication method provided by the present application will be described in detail with reference to the accompanying drawings.
请参考图3，该图3是根据一示例性实施例提供的通信方法的流程图，该方法可以应用于上述图2所示的实施环境中，该方法可以包括如下几个实现步骤：Please refer to FIG. 3 , which is a flow chart of a communication method provided according to an exemplary embodiment. The method can be applied in the implementation environment shown in FIG. 2 , and the method can include the following implementation steps:
步骤301：接收第一接入网设备发送的第一资源信息，该第一资源信息指示的第一资源包括第一小区 内的飞行设备通信所占用的资源，该第一小区为由该第一接入网设备提供通信服务的小区。Step 301: Receive first resource information sent by a first access network device, where the first resource indicated by the first resource information includes resources occupied by flight equipment communications within a first cell, and the first cell is a cell where communication services are provided by the first access network device.
作为一种示例，该第一接入网设备在确定第一小区内有飞行设备预切换至第二小区的情况下，可以向第二接入网设备发送第一资源信息，以告知第二接入网设备第一小区内已被占用的资源，也即是，该第二接入网设备接收该第一资源信息后，可以确定该第一小区内的飞行设备通信所占用的资源。As an example, when the first access network device determines that a flying device in the first cell is pre-switched to the second cell, the first access network device can send first resource information to the second access network device to inform the second access network device of the occupied resources in the first cell. That is, after receiving the first resource information, the second access network device can determine the resources occupied by the flying device communication in the first cell.
作为一种示例，若在接收该第一资源信息之前未开启该第二小区的网络覆盖，接收该第一接入网设备发送的该第一资源信息后，开启该第二小区的网络覆盖。As an example, if the network coverage of the second cell is not enabled before receiving the first resource information, the network coverage of the second cell is enabled after receiving the first resource information sent by the first access network device.
也就是说，如果在接收该第一资源信息之前，本端的第二接入网设备未开启该第二小区的网络覆盖，即该第二接入网设备处于关闭状态，则在接收该第一接入网设备发送的该第一资源信息后，可以认为第一小区内有飞行设备预切换至第二小区内，所以，为了能够保证通信服务的连续性，该第二接入网设备可以开启该第二小区的网络覆盖，以便于第一小区内的飞行设备能够成功切换至第二小区内。That is to say, if before receiving the first resource information, the second access network device on this end has not enabled the network coverage of the second cell, that is, the second access network device is in a closed state, then after receiving the first resource information sent by the first access network device, it can be considered that there is a flying device in the first cell that is pre-switched to the second cell. Therefore, in order to ensure the continuity of communication services, the second access network device can enable the network coverage of the second cell so that the flying equipment in the first cell can successfully switch to the second cell.
其中，第二接入网设备在初始状态下关闭，可以避免对第一小区产生干扰，从而可以避免第一小区内的飞行设备飞入第一小区和第二小区的重叠区域时受到干扰。Among them, the second access network device is turned off in the initial state, which can avoid interference with the first cell, thereby preventing the flying equipment in the first cell from being interfered when it flies into the overlapping area of the first cell and the second cell.
步骤302：根据该第一资源信息，分配与该第一资源不重叠的第二资源，该第二资源用于传输第二小区的系统广播信息，该第二小区为由本端的第二接入网设备提供通信服务的小区。Step 302: According to the first resource information, a second resource that does not overlap with the first resource is allocated, and the second resource is used to transmit system broadcast information of a second cell, and the second cell is a cell for which communication services are provided by a second access network device at the local end.
该第二接入网设备接收到该第一资源信息后，可以分配用于传输第二小区的系统广播信息的第二资源，为了避免与第一资源发生冲突，该第二接入网设备在分配第二资源时，可以尽量避免与该第一资源重叠。第一小区内待切换的飞行设备可以根据系统广播信息切换至第二小区内，由于用于传输该系统广播信息的第二资源与第一资源不冲突，所以，可以保证飞行设备在不受干扰的情况下，成功切换至第二小区内，保证了飞行设备的通信质量，避免出现链路失败的情况。After receiving the first resource information, the second access network device can allocate a second resource for transmitting the system broadcast information of the second cell. In order to avoid conflicts with the first resource, the second access network device can try to avoid overlapping with the first resource when allocating the second resource. The flight equipment to be switched in the first cell can be switched to the second cell according to the system broadcast information. Since the second resource for transmitting the system broadcast information does not conflict with the first resource, it can be ensured that the flight equipment is successfully switched to the second cell without interference, thereby ensuring the communication quality of the flight equipment and avoiding link failure.
作为一种示例，该第二资源还包括用于传输参考信号的资源。也就是说，该第二接入网设备分配的第二资源还包括用于传输参考信号的资源，以便于飞行设备可以基于对该参考信号的测量，完成从第一小区至第二小区的切换。As an example, the second resource also includes a resource for transmitting a reference signal. That is, the second resource allocated by the second access network device also includes a resource for transmitting a reference signal, so that the flight device can complete the switching from the first cell to the second cell based on the measurement of the reference signal.
作为一种示例，若该飞行设备成功切换至该第二小区内，该第二接入网设备可以向该第一接入网设备发送关闭指示，该关闭指示用于指示第一接入网设备关闭对第一小区的网络覆盖。也即是，在该飞行设备成功切换至第二小区的情况下，该第二接入网设备可以指示该第一接入网设备关闭，以避免第一接入网设备的第一小区对其他小区产生干扰。As an example, if the aircraft device successfully switches to the second cell, the second access network device may send a shutdown instruction to the first access network device, and the shutdown instruction is used to instruct the first access network device to shut down the network coverage of the first cell. That is, when the aircraft device successfully switches to the second cell, the second access network device may instruct the first access network device to shut down to avoid the first cell of the first access network device from interfering with other cells.
当然，在一些实施例中，该第一接入网设备在确定飞行设备成功切换至第二小区，且第一小区内不再存在其他飞行设备的情况下，可以自动关闭对第一小区的网络覆盖。Of course, in some embodiments, the first access network device may automatically shut down network coverage of the first cell when it is determined that the flying device has successfully switched to the second cell and there are no other flying devices in the first cell.
进一步地，该第二小区内也可能存在接入该第二小区的飞行设备，在该种情况下，该第二接入网设备需要控制第二小区内的飞行设备进行切换，其具体还包括如下实现步骤。Furthermore, there may be flying devices accessing the second cell in the second cell. In this case, the second access network device needs to control the flying devices in the second cell to switch, which specifically includes the following implementation steps.
步骤303：若该第二小区内存在接入该第二小区的飞行设备，如果根据该第二小区内的飞行设备的上报数据确定该第二小区内存在满足切换条件的第一飞行设备，向第三小区的第三接入网设备发送第二资源信息。Step 303: If there is an aircraft device connected to the second cell in the second cell, if it is determined based on the reported data of the aircraft device in the second cell that there is a first aircraft device that meets the switching condition in the second cell, second resource information is sent to a third access network device in the third cell.
其中，该第三小区为该第一飞行设备待切换的小区，该第二资源信息指示的第三资源包括该第二小区内的飞行设备通信所占用的资源。The third cell is a cell to which the first flying device is to be switched, and the third resources indicated by the second resource information include resources occupied by flying device communications within the second cell.
作为一种示例，该上报数据包括对应的飞行设备的地理位置信息和对应的飞行设备测量的信号强度中的至少一个。进一步地，该地理位置信息可以包括经纬度信息和/或高度信息。另外，该信号强度可以为RSRP(Reference Signal Receiving Power，参考信号接收功率)。As an example, the reported data includes at least one of the geographic location information of the corresponding flight device and the signal strength measured by the corresponding flight device. Further, the geographic location information may include latitude and longitude information and/or altitude information. In addition, the signal strength may be RSRP (Reference Signal Receiving Power).
作为一种示例，满足切换条件的第一飞行设备是指：与第二小区的小区中心的距离大于一定阈值的飞行设备，该阈值可以根据实际需求进行设置。As an example, the first flying device that meets the switching condition refers to a flying device whose distance from the cell center of the second cell is greater than a certain threshold, and the threshold can be set according to actual needs.
作为一种示例，该第二小区内的飞行设备可以包括从第一小区内切换过来的飞行设备，另外，该第二小区内的飞行设备的数量可能为一个，也可能为多个，本申请实施例对此不做限定。As an example, the flying equipment in the second cell may include flying equipment switched from the first cell. In addition, the number of flying equipment in the second cell may be one or more, which is not limited in the embodiments of the present application.
其中，本申请中所述的第二小区内的飞行设备是指接入该第二小区的飞行设备，为了便于描述，下文直接描述为第二小区内的飞行设备。同理，第一小区内的飞行设备是指接入该第一小区的飞行设备。The flying equipment in the second cell mentioned in the present application refers to the flying equipment connected to the second cell. For the convenience of description, the flying equipment in the second cell is directly described below. Similarly, the flying equipment in the first cell refers to the flying equipment connected to the first cell.
若该第二小区内存在接入该第二小区的飞行设备，该第二小区内的飞行设备可以向该第二接入网设备反馈上报数据，该第二接入网设备接收该第二小区内的飞行设备发送的上报数据，并根据该上报数据判断是否存在满足切换条件的第一飞行设备，如果存在，向第三小区的第三接入网设备发送第二资源信息，以告知该第三接入网设备该第二小区内的飞行设备通信所占用的资源，从而使得该第三接入网设备在分配用于传输第三小区的系统广播信息的资源时，可以尽量避免与该第二小区中已被占用的资源重叠。If there is a flying device connected to the second cell within the second cell, the flying device within the second cell can feedback reporting data to the second access network device. The second access network device receives the reporting data sent by the flying device within the second cell, and determines whether there is a first flying device that meets the switching condition based on the reporting data. If so, second resource information is sent to the third access network device of the third cell to inform the third access network device of the resources occupied by the communication of the flying device within the second cell, so that the third access network device can try to avoid overlapping with the occupied resources in the second cell when allocating resources for transmitting system broadcast information of the third cell.
作为一种示例，该第二小区内包括一个飞行设备，在该种情况下，确定是否存在满足切换条件的第一飞行设备的具体实现可以包括：若根据该飞行设备的上报数据，确定该飞行设备飞离第二小区的小区中心且与该小区中心的距离大于第一指定距离阈值，将该飞行设备确定为该第一飞行设备。As an example, the second cell includes a flying device. In this case, the specific implementation of determining whether there is a first flying device that meets the switching conditions may include: if it is determined based on the reported data of the flying device that the flying device has flown away from the cell center of the second cell and the distance from the cell center is greater than a first specified distance threshold, the flying device is determined to be the first flying device.
其中，该第一指定距离阈值可以根据实际需求进行设置，通常情况下，该第一指定距离阈值与飞行设 备的飞行高度有关，飞行高度越高，说明所在的小区的面积越大，不难理解，此时，该第一指定距离阈值就越大。也即是，针对不同飞行高度，可以设有不同的第一指定距离阈值。The first designated distance threshold can be set according to actual needs. Generally, the first designated distance threshold is related to the flight altitude of the flight device. The higher the flight altitude, the larger the area of the cell. It is not difficult to understand that at this time, the first designated distance threshold is larger. That is, different first designated distance thresholds can be set for different flight altitudes.
不难理解，若该第二小区内仅包括一个飞行设备，如果该飞行设备飞离第二小区的小区中心，且与该第二小区的小区中心的距离大于第一指定距离阈值，说明该飞行设备与第二小区的小区中心较远，从而可以将该飞行设备确定为满足切换条件的飞行设备。It is not difficult to understand that if the second cell includes only one flying device, if the flying device flies away from the cell center of the second cell and the distance from the cell center of the second cell is greater than the first specified distance threshold, it means that the flying device is far away from the cell center of the second cell, so that the flying device can be determined as a flying device that meets the switching conditions.
根据该上报数据包括的内容不同，基于该上报数据确定该飞行设备远离该第二小区的小区中心的具体实现也不同。譬如，若该上报数据包括该飞行设备测量的信号强度，该信号强度与距离可以存在一个预设的映射关系，如此，可以根据该信号强度确定该飞行设备与该第二小区的小区中心的距离，然后，可以结合该飞行设备的地理位置信息的变化，判断该飞行设备是否是飞离第二小区的小区中心。再如，若该信号强度持续低于一定阈值，可以确定该飞行设备与该第二小区的小区中心的距离大于第一指定距离阈值，且该飞行设备是飞离该第二小区的小区中心的。Depending on the content included in the reported data, the specific implementation of determining that the flight device is far away from the cell center of the second cell based on the reported data is also different. For example, if the reported data includes the signal strength measured by the flight device, there may be a preset mapping relationship between the signal strength and the distance. In this way, the distance between the flight device and the cell center of the second cell can be determined based on the signal strength. Then, combined with the change in the geographical location information of the flight device, it can be determined whether the flight device is flying away from the cell center of the second cell. For another example, if the signal strength is continuously lower than a certain threshold, it can be determined that the distance between the flight device and the cell center of the second cell is greater than the first specified distance threshold, and the flight device is flying away from the cell center of the second cell.
再如，若该上报数据包括该飞行设备的地理位置信息，则可以根据该地理位置信息确定飞行设备是否飞离第二小区的小区中心，以及当前的位置与第二小区的小区中心的距离，即确定该飞行设备是否远离该第二小区的小区中心。For example, if the reported data includes the geographic location information of the flying device, it is possible to determine whether the flying device has flown away from the cell center of the second cell and the distance between the current location and the cell center of the second cell based on the geographic location information, that is, to determine whether the flying device is far away from the cell center of the second cell.
又如，若上报数据包括飞行设备的地理位置信息和信号强度，则该第二接入网设备可以基于该信号强度，结合地理位置信息，判断该飞行设备是否远离该第二小区的小区中心。For another example, if the reported data includes geographic location information and signal strength of the flying device, the second access network device can determine whether the flying device is far away from the cell center of the second cell based on the signal strength and the geographic location information.
需要说明的是，上述在向第三小区的第三接入网设备发送第二资源信息之前，可以确定第三小区，即确定该第一飞行设备飞向哪个小区。作为一种示例，若与该第二小区相邻的第三小区的数量仅包括一个，则在该飞行设备远离该第二小区的情况下，可以直接确定第三小区。作为另一种示例，若与该第二小区相邻的第三小区的数量为多个，则在该飞行设备远离该第二小区的情况下，该第二接入网设备可以根据该飞行设备的地理位置信息确定第三小区，譬如，根据飞行设备的经纬度信息确定第三小区。It should be noted that, before sending the second resource information to the third access network device of the third cell, the third cell can be determined, that is, the cell to which the first flying device is flying can be determined. As an example, if the number of third cells adjacent to the second cell includes only one, then when the flying device is far away from the second cell, the third cell can be directly determined. As another example, if the number of third cells adjacent to the second cell is multiple, then when the flying device is far away from the second cell, the second access network device can determine the third cell according to the geographical location information of the flying device, for example, determine the third cell according to the latitude and longitude information of the flying device.
作为另一种示例，该第二小区内包括多个飞行设备，在该种情况下，确定是否存在满足切换条件的第一飞行设备的具体实现可以包括：根据该多个飞行设备的上报数据，分别确定该多个飞行设备与该第二小区的小区中心的距离，从该多个飞行设备中确定与该小区中心的距离大于第二指定距离阈值的飞行设备，将所确定的飞行设备中飞离该第二小区的小区中心且与该小区中心的距离最远的飞行设备确定为该第一飞行设备。As another example, the second cell includes multiple flying devices. In this case, the specific implementation of determining whether there is a first flying device that meets the switching condition may include: determining the distances between the multiple flying devices and the cell center of the second cell respectively based on the reported data of the multiple flying devices, determining from the multiple flying devices a flying device whose distance from the cell center is greater than a second specified distance threshold, and determining the flying device among the determined flying devices that flies away from the cell center of the second cell and is the farthest from the cell center as the first flying device.
其中，该第二指定距离阈值可以根据实际需求进行设置，该第二指定距离阈值可以与上述第一指定距离阈值相同，也可以与上述第一指定距离阈值不同，本申请实施例对此不做限定。通常情况下，该第二指定距离阈值与飞行设备的飞行高度有关，飞行高度越高，说明所在的小区的面积越大，不难理解，此时，该第二指定距离阈值就越大。也即是，针对不同飞行高度，可以设有不同的第二指定距离阈值。Among them, the second specified distance threshold can be set according to actual needs. The second specified distance threshold can be the same as the above-mentioned first specified distance threshold, or it can be different from the above-mentioned first specified distance threshold. The embodiment of the present application does not limit this. Usually, the second specified distance threshold is related to the flight altitude of the flight equipment. The higher the flight altitude, the larger the area of the cell where it is located. It is not difficult to understand that at this time, the second specified distance threshold is larger. That is, different second specified distance thresholds can be set for different flight altitudes.
若该第二小区内包括多个飞行设备，该第二接入网设备以第一个飞入第三小区的覆盖区域内的飞行设备为基准，即将该第一个飞入第三小区的覆盖区域内的飞行设备确定为第一飞行设备。If the second cell includes multiple flying devices, the second access network device uses the first flying device that flies into the coverage area of the third cell as a reference, ie, determines the first flying device that flies into the coverage area of the third cell as the first flying device.
需要说明的是，在该种情况下，判断是否存在满足切换条件的第一飞行设备的方式与第二小区内存在一个接入该第二小区的飞行设备时的判断方式相同。另外，该第三小区的确定方式可以参见上文。It should be noted that, in this case, the method of determining whether there is a first flying device that meets the switching condition is the same as the method of determining when there is a flying device accessing the second cell in the second cell. In addition, the method of determining the third cell can refer to the above.
作为一种示例，该第三小区可能与上述第一小区相同，在该种情况下，该第一小区和第二小区均处于开启状态，第一接入网设备将第一小区内的飞行设备通信所占用的资源告知给第二接入网设备，并且，该第二接入网设备将第二小区内的飞行设备通信所占用的资源告知给第一接入网设备，如此，以便于该第一接入网设备或第二接入网设备后续在分配资源时，尽量避免冲突。As an example, the third cell may be the same as the first cell mentioned above. In this case, the first cell and the second cell are both in an on state, and the first access network device informs the second access network device of the resources occupied by the communication of the flight equipment in the first cell, and the second access network device informs the first access network device of the resources occupied by the communication of the flight equipment in the second cell. In this way, the first access network device or the second access network device can avoid conflicts as much as possible when allocating resources subsequently.
进一步地，该第一接入网设备还将该第一小区用于传输系统广播信息和参考信号的资源告知给第二接入网设备，同理，该第二接入网设备还将该第二小区用于传输系统广播信息和参考信号的资源告知给第一接入网设备。Furthermore, the first access network device also informs the second access network device of the resources used by the first cell for transmitting system broadcast information and reference signals. Similarly, the second access network device also informs the first access network device of the resources used by the second cell for transmitting system broadcast information and reference signals.
作为一种示例，在该第一小区和第二小区均处于开启状态下，该第一接入网设备可以在确定第一小区内存在满足切换条件的第一飞行设备的情况下，再告知第二接入网设备该第一小区内的飞行设备所占用的资源和系统广播信息占用的资源。同理，该第二接入网设备也可以在确定第二小区内存在满足切换条件的第一飞行设备的情况下，再告知第一接入网设备该第二小区内的飞行设备所占用的资源和系统广播信息占用的资源。As an example, when both the first cell and the second cell are in an on state, the first access network device may, upon determining that there is a first flight device that meets the switching condition in the first cell, inform the second access network device of the resources occupied by the flight device in the first cell and the resources occupied by the system broadcast information. Similarly, upon determining that there is a first flight device that meets the switching condition in the second cell, the second access network device may inform the first access network device of the resources occupied by the flight device in the second cell and the resources occupied by the system broadcast information.
进一步地，若该第二小区内的飞行设备切换至该第三小区，关闭该第二小区的网络覆盖。也就是说，若该第二小区内的飞行设备均切换至该第三小区内，则该第二接入网设备可以自动关闭该第二小区的网络覆盖。其中，若该第二小区内存在多个接入该第二小区的飞行设备，则该第二接入网设备在第二小区内的最后一个飞行设备飞离该第二小区后关闭。Furthermore, if the flight equipment in the second cell switches to the third cell, the network coverage of the second cell is turned off. That is, if all the flight equipment in the second cell switches to the third cell, the second access network device can automatically turn off the network coverage of the second cell. If there are multiple flight equipments in the second cell that access the second cell, the second access network device is turned off after the last flight equipment in the second cell flies away from the second cell.
在另一实施例中，若该第二小区内的飞行设备切换至第三小区内，则该第二接入网设备在接收到第三接入网设备的关闭指示后，关闭对第二小区的网络覆盖。也即是，该第二接入网设备可以不自主关闭，而是在接收到关闭指示后再执行关闭操作。In another embodiment, if the flying device in the second cell switches to the third cell, the second access network device turns off the network coverage of the second cell after receiving the shutdown instruction from the third access network device. That is, the second access network device may not shut down autonomously, but perform the shutdown operation after receiving the shutdown instruction.
进一步地，上报数据包括对应的飞行设备的地理位置信息，若基于该地理位置信息确定该第二小区内的飞行设备的飞行高度大于指定高度阈值，则如果根据该第二小区内的飞行设备的上报数据确定该第二小区内存在满足切换条件的第一飞行设备，向第三小区的第三接入网设备发送第二资源信息。Furthermore, the reported data includes geographic location information of the corresponding flight device. If it is determined based on the geographic location information that the flight altitude of the flight device in the second cell is greater than a specified altitude threshold, then if it is determined based on the reported data of the flight device in the second cell that there is a first flight device that meets the switching conditions in the second cell, the second resource information is sent to the third access network device of the third cell.
其中，该指定高度阈值可以根据实际需求进行设置。The specified height threshold can be set according to actual needs.
也即是，该第二接入网设备可以根据飞行设备的地理位置信息，确定该飞行设备当前的飞行高度，如果该飞行高度大于指定高度阈值，可以认为该飞行设备所在的参考平面上各个小区之间存在大面积重叠，在该种情况下，执行上述提供的通信方法。That is, the second access network device can determine the current flight altitude of the flight device based on the geographic location information of the flight device. If the flight altitude is greater than the specified altitude threshold, it can be considered that there is a large overlap between the cells on the reference plane where the flight device is located. In this case, the communication method provided above is executed.
在本申请实施例中，接收第一接入网设备发送的第一资源的第一资源信息，第一资源包括第一接入网设备的第一小区内的飞行设备通信所占用的资源，也即是，第一接入网设备将第一小区内已被占用的资源告知第二接入网设备。如此，该第二接入网设备可以根据该第一资源信息，分配与第一资源不重叠的第二资源，该第二资源用于传输第二接入网设备的第二小区的系统广播信息，以便于飞行设备基于该系统广播信息切换至第二小区时，可以尽量避免小区间的同频干扰。In an embodiment of the present application, first resource information of a first resource sent by a first access network device is received, and the first resource includes resources occupied by the communication of the flight device in the first cell of the first access network device, that is, the first access network device notifies the second access network device of the resources that have been occupied in the first cell. In this way, the second access network device can allocate a second resource that does not overlap with the first resource based on the first resource information, and the second resource is used to transmit the system broadcast information of the second cell of the second access network device, so that when the flight device switches to the second cell based on the system broadcast information, the same-frequency interference between cells can be avoided as much as possible.
为了便于理解，接下来以几个具体示例对上述实现过程进行举例介绍。To facilitate understanding, the above implementation process is introduced below with several specific examples.
示例一：请参考图4，小区1和小区2在一段时间内仅存在一个飞行设备，该飞行设备位于该小区1内，且飞向小区2，该小区2处于未开启状态。Example 1: Please refer to FIG. 4 . There is only one aircraft in cell 1 and cell 2 within a period of time. The aircraft is located in cell 1 and flies to cell 2. Cell 2 is in an unactivated state.
小区1开启的情况下为该飞行设备提供空中通信服务。如果小区1和小区2是同频组网，那么，如果小区2开启，该小区2广播的信号可能会直接干扰小区1，譬如，若在该飞行设备飞行所经过的参考平面上，该小区1和小区2存在大面积的重叠区域，则飞行设备与小区1的通信可能会受到小区2广播的信号的强干扰，从而容易导致链路失败。When cell 1 is turned on, the aircraft will be provided with air communication services. If cell 1 and cell 2 are co-networked, then if cell 2 is turned on, the signal broadcast by cell 2 may directly interfere with cell 1. For example, if there is a large overlapping area between cell 1 and cell 2 on the reference plane that the aircraft flies over, the communication between the aircraft and cell 1 may be strongly interfered by the signal broadcast by cell 2, which may easily lead to link failure.
为此，飞行设备可以向地面基站1发送上报数据，该上报数据可以包括飞行设备测量到的信号强度，譬如，该信号强度为RSRP，其中，该地面基站1是指为小区1提供网络覆盖的基站。也即是，飞行设备可以将其测量到的信号强度反馈给地面基站1。To this end, the flying device may send reporting data to the ground base station 1, and the reporting data may include the signal strength measured by the flying device, for example, the signal strength is RSRP, wherein the ground base station 1 refers to a base station that provides network coverage for the cell 1. That is, the flying device may feed back the measured signal strength to the ground base station 1.
进一步地，该上报数据还可以包括该飞行设备的地理位置信息，即该飞行设备还可以将其地理位置信息反馈给该地面基站1，示例性地，该地理位置信息可以包括该飞行设备的经纬度信息和/或高度信息。Furthermore, the reported data may also include geographic location information of the flight device, that is, the flight device may also feed back its geographic location information to the ground base station 1. Exemplarily, the geographic location information may include latitude and longitude information and/or altitude information of the flight device.
若地面基站1根据飞行设备的上报数据确定该飞行设备远离小区1的中心，可以认为该飞行设备已经进入该地面基站1与该地面基站2的重叠区域。在该种请下，地面基站1可以将该飞行设备当前通信占用的资源的资源信息通过基站间的接口发送给地面基站2。其中，该资源信息可以包括时频资源信息和频域资源信息，该时域资源信息包括时域的长度和位置，频域资源维信息包括频域的长度和位置。If the ground base station 1 determines that the flying device is far away from the center of the cell 1 according to the reported data of the flying device, it can be considered that the flying device has entered the overlapping area of the ground base station 1 and the ground base station 2. In this case, the ground base station 1 can send the resource information of the resources currently occupied by the flying device for communication to the ground base station 2 through the interface between base stations. The resource information may include time-frequency resource information and frequency domain resource information, the time domain resource information includes the length and position of the time domain, and the frequency domain resource information includes the length and position of the frequency domain.
需要说明的是，为了避免干扰，该地面基站1也应该尽量避免将飞行设备调度到与该地面基站2固有的系统广播信息的资源重叠的区域。It should be noted that, in order to avoid interference, the ground base station 1 should also try to avoid scheduling the flying equipment to an area that overlaps with the resources of the system broadcast information inherent to the ground base station 2.
对于地面基站2来说，该地面基站2接收到来自该地面基站1发送的资源信息后，可以确定飞行设备预切换至小区2，在该种情况下，该地面基站2开启并完成小区2的覆盖。在实施中，该地面基站2可以根据该地面基站1发送的资源信息，配置用于传输小区2的系统广播信息以及参考信号等的资源，并在配置过程中，可以尽量避免与飞行设备在小区1中的资源重叠。For the ground base station 2, after receiving the resource information sent from the ground base station 1, the ground base station 2 can determine that the flying device is pre-switched to the cell 2. In this case, the ground base station 2 is turned on and completes the coverage of the cell 2. In implementation, the ground base station 2 can configure resources for transmitting the system broadcast information and reference signals of the cell 2 according to the resource information sent by the ground base station 1, and in the configuration process, it can try to avoid overlapping with the resources of the flying device in the cell 1.
如图5所示，地面基站2分配的用于传输小区2的系统广播信息的资源为资源2，而不是资源1。如此，地面基站1对飞行设备占用资源的配置，或者，地面基站2对系统广播信息的配置不重叠，以避免相互干扰。As shown in FIG5 , the resource allocated by ground base station 2 for transmitting the system broadcast information of cell 2 is resource 2, not resource 1. In this way, the configuration of the resources occupied by the flying equipment by ground base station 1, or the configuration of the system broadcast information by ground base station 2, does not overlap to avoid mutual interference.
示例二：请参考图6，小区1内存在多个飞行设备，包括飞行设备1和飞行设备2，且飞向小区2，该小区2处于未开启状态。Example 2: Please refer to FIG6 . There are multiple aircrafts in cell 1, including aircraft 1 and aircraft 2, and they are flying towards cell 2, which is in an unactivated state.
小区1开启的情况下为该飞行设备1和飞行设备2提供空中通信服务，该飞行设备1和飞行设备2均可以向地面基站1发送上报数据，该上报数据可以包括对应的飞行设备测量到的信号强度，譬如，该信号强度为RSRP。When cell 1 is turned on, air communication services are provided for the flight device 1 and the flight device 2. Both the flight device 1 and the flight device 2 can send reporting data to the ground base station 1. The reporting data may include the signal strength measured by the corresponding flight device, for example, the signal strength is RSRP.
进一步地，该上报数据还可以包括对应的飞行设备的地理位置信息，即该飞行设备1和飞行设备2还可以将各自的地理位置信息反馈给该地面基站1，示例性地，该地理位置信息可以包括对应的飞行设备的经度信息和/或纬度信息。Furthermore, the reported data may also include geographic location information of the corresponding flight equipment, that is, the flight equipment 1 and the flight equipment 2 may also feed back their respective geographic location information to the ground base station 1. Exemplarily, the geographic location information may include longitude information and/or latitude information of the corresponding flight equipment.
若地面基站1根据飞行设备1和飞行设备2的上报数据确定存在满足切换条件的飞行设备，可以认为该满足切换条件的飞行设备已经进入该地面基站1与该地面基站2的重叠区域，譬如，请参考图6，若确定飞行设备2测量到的信号强度持续低于一定的门限，且根据飞行设备2的地理位置信息确定该飞行设备2远离小区1的中心，则确定飞行设备2满足切换条件。在该种请下，地面基站1可以将该飞行设备1和飞行设备2当前通信占用的资源的资源信息通过基站间的接口发送给地面基站2。其中，该资源信息可以包括时频资源信息和频域资源信息，该时域资源信息可以包括时域的长度和位置，频域资源维信息可以包 括频域的长度和位置。If the ground base station 1 determines that there is an aerial device that meets the switching condition based on the reported data of the aerial device 1 and the aerial device 2, it can be considered that the aerial device that meets the switching condition has entered the overlapping area of the ground base station 1 and the ground base station 2. For example, please refer to Figure 6. If it is determined that the signal strength measured by the aerial device 2 is continuously lower than a certain threshold, and it is determined that the aerial device 2 is far away from the center of the cell 1 based on the geographical location information of the aerial device 2, it is determined that the aerial device 2 meets the switching condition. In this case, the ground base station 1 can send the resource information of the resources currently occupied by the aerial device 1 and the aerial device 2 to the ground base station 2 through the interface between base stations. Among them, the resource information can include time-frequency resource information and frequency domain resource information. The time domain resource information can include the length and position of the time domain, and the frequency domain resource dimension information can include the length and position of the frequency domain.
对于地面基站2来说，该地面基站2接收到来自该地面基站1发送的资源信息后，可以确定有飞行设备预切换至小区2，在该种情况下，该地面基站2开启并完成小区2的覆盖，也即是，该小区2的开启时机应以最先飞离小区1，且飞入小区2所在区域的飞行设备为准。For the ground base station 2, after receiving the resource information sent by the ground base station 1, the ground base station 2 can determine that a flying device is pre-switched to cell 2. In this case, the ground base station 2 turns on and completes the coverage of cell 2. That is, the timing of turning on cell 2 should be based on the flying device that first flies away from cell 1 and flies into the area where cell 2 is located.
在实施中，该地面基站2可以根据该地面基站1发送的资源信息，配置其系统广播信息以及参考信号等资源，并在配置过程中，可以尽量避免与飞行设备在小区1中的资源重叠。如图7所示，地面基站2对系统广播信息的配置不重叠，以避免相互干扰。In implementation, the ground base station 2 can configure its system broadcast information and reference signal and other resources according to the resource information sent by the ground base station 1, and in the configuration process, it can try to avoid overlapping with the resources of the flying equipment in the cell 1. As shown in FIG7 , the configuration of the system broadcast information by the ground base station 2 does not overlap to avoid mutual interference.
示例三：小区1和小区2都处于开启状态，小区1内存在至少一个飞行设备，且至少一个飞行设备飞向小区2，该小区2内存在至少一个飞行设备，且至少一个飞行设备飞向小区1。请参考图8，这里以该小区1内存在接入该小区1的飞行设备1，小区2内存在接入该小区2的飞行设备2为例进行举例说明。Example 3: Both cell 1 and cell 2 are in the on state, there is at least one flying device in cell 1, and at least one flying device flies to cell 2, and there is at least one flying device in cell 2, and at least one flying device flies to cell 1. Please refer to FIG8 , where an example is given in which there is a flying device 1 in cell 1 connected to cell 1, and there is a flying device 2 in cell 2 connected to cell 2.
该飞行设备1可以向地面基站1发送上报数据，该飞行设备2可以向地面基站2发送上报数据，该上报数据可以包括对应的飞行设备测量到的信号强度，譬如，该信号强度为RSRP。The aerial device 1 may send reporting data to the ground base station 1, and the aerial device 2 may send reporting data to the ground base station 2. The reporting data may include the signal strength measured by the corresponding aerial device, for example, the signal strength is RSRP.
进一步地，该上报数据还可以包括对应的飞行设备的地理位置信息，即该飞行设备1可以将其地理位置信息反馈该地面基站1，该飞行设备2可以将其地理位置信息反馈给该地面基站2，示例性地，该地理位置信息可以包括对应的飞行设备的经纬度信息和/或高度信息。Furthermore, the reported data may also include geographic location information of the corresponding flight device, that is, the flight device 1 may feed back its geographic location information to the ground base station 1, and the flight device 2 may feed back its geographic location information to the ground base station 2. Exemplarily, the geographic location information may include the latitude and longitude information and/or altitude information of the corresponding flight device.
若地面基站1或地面基站2根据飞行设备的上报数据确定存在满足切换条件的飞行设备，可以认为该满足切换条件的飞行设备已经进入该小区1与该小区2的重叠区域。譬如，请参考图8，若确定飞行设备2测量到的信号强度持续低于一定的门限，且根据飞行设备2的地理位置信息确定该飞行设备2远离小区2的小区中心，则确定飞行设备2满足切换条件。在该种请下，地面基站2可以将飞行设备2当前通信占用的资源的资源信息通过基站间的接口发送给地面基站1，另外，该地面基站2还可以将系统广播信息占用的资源信息通知给小区1。其中，该资源信息可以包括时频资源信息和频域资源信息，该时域资源信息可以包括时域的长度和位置，频域资源维信息可以包括频域的长度和位置。If the ground base station 1 or the ground base station 2 determines that there is a flying device that meets the switching condition based on the reported data of the flying device, it can be considered that the flying device that meets the switching condition has entered the overlapping area of the cell 1 and the cell 2. For example, please refer to Figure 8, if it is determined that the signal strength measured by the flying device 2 is continuously lower than a certain threshold, and the flying device 2 is determined to be far away from the cell center of the cell 2 based on the geographical location information of the flying device 2, it is determined that the flying device 2 meets the switching condition. In this case, the ground base station 2 can send the resource information of the resources currently occupied by the flying device 2 to the ground base station 1 through the interface between base stations. In addition, the ground base station 2 can also notify the cell 1 of the resource information occupied by the system broadcast information. Among them, the resource information can include time-frequency resource information and frequency domain resource information. The time domain resource information can include the length and position of the time domain, and the frequency domain resource dimension information can include the length and position of the frequency domain.
对于地面基站1来说，该地面基站1接收到来自该地面基站2发送的资源信息后，可以确定有飞行设备预切换至小区1，在该种情况下，该地面基站1可以根据该地面基站2发送的资源信息，配置用于传输小区1的系统广播信息以及参考信号等的资源，并在配置过程中，可以尽量避免与飞行设备在小区2中的资源重叠。如图9所示，地面基站1对系统广播信息的配置不重叠，以避免相互干扰。For the ground base station 1, after receiving the resource information sent from the ground base station 2, the ground base station 1 can determine that there is a flying device pre-switching to cell 1. In this case, the ground base station 1 can configure resources for transmitting the system broadcast information and reference signals of cell 1 according to the resource information sent by the ground base station 2, and in the configuration process, it can try to avoid overlapping with the resources of the flying device in cell 2. As shown in Figure 9, the configuration of the system broadcast information by the ground base station 1 does not overlap to avoid mutual interference.
此外，该地面基站1在根据飞行设备1的上报数据确定该飞行设备远离小区1的中心，可以认为该飞行设备1进入小区2的覆盖区域，该地面基站1可以将该飞行设备1当前通信占用的资源的资源信息通过基站间的接口发送给地面基站2，另外，该地面基站1还可以将系统广播信息占用的资源信息通知给小区2，以便于该地面基站2在后续的资源分配中避免系统广播信息占用的资源与对方的飞行设备通信占用的资源发生冲突，如图9所示。In addition, when the ground base station 1 determines that the flying device is far away from the center of the cell 1 based on the reported data of the flying device 1, it can be considered that the flying device 1 has entered the coverage area of the cell 2. The ground base station 1 can send the resource information of the resources currently occupied by the flying device 1 for communication to the ground base station 2 through the interface between base stations. In addition, the ground base station 1 can also notify the cell 2 of the resource information occupied by the system broadcast information, so that the ground base station 2 can avoid the conflict between the resources occupied by the system broadcast information and the resources occupied by the other party's flying device communication in the subsequent resource allocation, as shown in Figure 9.
需要说明的是，上述图8是以飞行设备2先进入重叠区域为例进行说明，在另一实施例中，若飞行设备1和飞行设备2同时进入重叠区域，则地面基站1和地面基站2在分配资源时，可以协商如何分配，以避免所分配的资源重叠。It should be noted that the above Figure 8 is illustrated by taking the example that the flying device 2 enters the overlapping area first. In another embodiment, if the flying device 1 and the flying device 2 enter the overlapping area at the same time, the ground base station 1 and the ground base station 2 can negotiate how to allocate resources when allocating resources to avoid overlapping of the allocated resources.
另外，还需要说明的是，上述是以地面基站1或地面基站2在检测到飞行设备可能进入重叠区域后，再将飞行设备已占用的资源和系统广播信息占用的资源通知给对方为例进行说明。在另一实施例中，该地面基站1、地面基站2还可以在检测到有飞行设备存在的情况下，直接将飞行设备已占用的资源和系统广播信息占用的资源通知给对方，不需要判断后在发送，本申请实施例对此不做限定。In addition, it should be noted that the above description is based on the example that the ground base station 1 or the ground base station 2 notifies the other party of the resources occupied by the flying device and the resources occupied by the system broadcast information after detecting that the flying device may enter the overlapping area. In another embodiment, the ground base station 1 and the ground base station 2 can also directly notify the other party of the resources occupied by the flying device and the resources occupied by the system broadcast information when the flying device is detected, without the need for judgment before sending, and the embodiment of the present application does not limit this.
请参考图10，该图10是根据另一示例性实施例的提供的通信方法的流程图，该通信方法可以应用于上述图2所示的实施环境中，该方法可以包括如下几个步骤：Please refer to FIG. 10 , which is a flow chart of a communication method provided according to another exemplary embodiment. The communication method can be applied in the implementation environment shown in FIG. 2 , and the method can include the following steps:
步骤1001：通过第一波束对第一小区进行网络覆盖。Step 1001: Provide network coverage for a first cell through a first beam.
通常情况下，该第一波束的宽度比较宽，譬如可以实现该第一小区的全网覆盖，在一些实施例中，该第一波束又可以称为宽波束。也即是，该第一接入网设备可以对该第一小区进行全网覆盖。Typically, the width of the first beam is relatively wide, for example, it can achieve full network coverage of the first cell, and in some embodiments, the first beam can also be called a wide beam. That is, the first access network device can provide full network coverage of the first cell.
作为一种示例，接收该第二小区的第二接入网设备发送的第一消息，该第一消息用于指示该第一接入网设备开启该第一小区的网络覆盖，若当前未开启该第一小区的网络覆盖，则通过该第一波束对该第一小区进行网络覆盖。As an example, a first message sent by a second access network device of the second cell is received, and the first message is used to instruct the first access network device to enable network coverage of the first cell. If the network coverage of the first cell is not currently enabled, the first cell is covered by the first beam.
也即是，该第一接入网设备预先可能未开启第一小区的网络覆盖，譬如，若该第一小区内不存在接入该第一小区的飞行设备，则该第一接入网设备可以处于关闭状态。直到接收到第二小区的第二接入网设备发送的第一消息时，说明第二小区内可能有飞行设备预切换过来，所以，该第一接入网设备接收该第一消息后开启对该第一小区的网络覆盖。That is, the first access network device may not have enabled network coverage of the first cell in advance. For example, if there is no flying device connected to the first cell in the first cell, the first access network device may be in a closed state. Until the first message sent by the second access network device of the second cell is received, it indicates that a flying device may be pre-switched in the second cell. Therefore, the first access network device enables network coverage of the first cell after receiving the first message.
步骤1002：在第一飞行设备切换至该第一小区的情况下，通过第二波束采用波束追踪的方式为该第一 飞行设备提供通信服务。其中，该第二波束的波束宽度小于该第一波束的波束宽度。Step 1002: When the first aerial device switches to the first cell, a communication service is provided to the first aerial device by using a second beam in a beam tracking manner, wherein a beam width of the second beam is smaller than a beam width of the first beam.
其中，波束追踪是指根据被追踪的飞行设备的飞行状态数据，不断调整第二波束的发射方向，以便于通过第二波束为该被追踪的飞行设备提供连续的通信服务。Among them, beam tracking refers to continuously adjusting the emission direction of the second beam according to the flight status data of the tracked flying device, so as to provide continuous communication services to the tracked flying device through the second beam.
作为一种示例，该飞行状态数据可以包括但不限于速度和方向。As an example, the flight status data may include, but is not limited to, speed and direction.
作为一种示例，在第一飞行设备切换至该第一小区的情况下，通过第二波束采用波束追踪的方式为该第一飞行设备提供通信服务的具体实现可以包括：在第一飞行设备切换至该第一小区的情况下，接收第一飞行设备的上报数据，该上报数据包括该第一飞行设备的飞行状态数据，根据该飞行状态数据，通过该第二波束采用波束追踪的方式为该第一飞行设备提供通信服务。As an example, when the first flying device switches to the first cell, the specific implementation of providing communication services to the first flying device by using the second beam in a beam tracking manner may include: when the first flying device switches to the first cell, receiving reported data from the first flying device, the reported data including flight status data of the first flying device, and providing communication services to the first flying device by using the second beam in a beam tracking manner based on the flight status data.
也就是说，该第一飞行设备切换至该第一小区后，可以不断地向该第一接入网设备发送上报数据，该上报数据中可以包括该第一飞行设备的飞行状态数据，譬如，该飞行状态数据包括该第一飞行设备的速度和方向。如此，该第一接入网设备可以根据第一飞行设备的速度和方向，不断调整第二波束的发射方向、功率等参数，从而实现对该第一飞行设备进行波束追踪，以为该第一飞行设备提供连续的通信服务。That is to say, after the first flying device switches to the first cell, it can continuously send reporting data to the first access network device, and the reporting data may include the flight status data of the first flying device, for example, the flight status data includes the speed and direction of the first flying device. In this way, the first access network device can continuously adjust the transmission direction, power and other parameters of the second beam according to the speed and direction of the first flying device, thereby realizing beam tracking for the first flying device, so as to provide continuous communication services for the first flying device.
需要说明的是，对于其他小区的接入网设备，均可以采用上述方式，对所接入的飞行设备进行波束追踪，下文不再重复赘述。It should be noted that the above method can be used for access network equipment in other cells to perform beam tracking on the connected flying equipment, which will not be repeated below.
其中，该第二波束的宽度通常很窄，可以根据实际需求进行设置，譬如，可以由该第一接入网设备来进行配置。在一些实施例中，该第二波束又可以称为窄波束。The width of the second beam is usually very narrow and can be set according to actual needs, for example, it can be configured by the first access network device. In some embodiments, the second beam can also be called a narrow beam.
作为一种示例，该第一飞行设备可以是从第二小区切换至第一小区的飞行设备。在该第一飞行设备切换至该第一小区的情况下，该第一接入网设备可以通过窄波束为该第一飞行设备提供通信服务，即从宽波束切换为窄波束为该第一飞行设备提供通信服务。As an example, the first flight device may be a flight device that switches from the second cell to the first cell. When the first flight device switches to the first cell, the first access network device may provide communication services for the first flight device through a narrow beam, that is, switching from a wide beam to a narrow beam to provide communication services for the first flight device.
作为一种示例，接收该第一飞行设备发送的上报数据，该上报数据包括第一信号强度，该第一信号强度是该第一飞行设备在由该第二波束提供通信服务的情况下测量的。若该第一信号强度大于第一强度阈值，向第二小区的第二接入网设备发送关闭指示，该关闭指示用于指示该第二接入网设备关闭该第二小区的网络覆盖，该第二小区为该第一飞行设备切换前所在的小区。As an example, report data sent by the first flight device is received, and the report data includes a first signal strength, and the first signal strength is measured by the first flight device when the communication service is provided by the second beam. If the first signal strength is greater than a first strength threshold, a shutdown indication is sent to a second access network device of a second cell, and the shutdown indication is used to instruct the second access network device to shut down the network coverage of the second cell, and the second cell is the cell where the first flight device is located before switching.
其中，该第一强度阈值可以根据实际需求进行设置，譬如，可以由该第一接入网设备进行设置。The first strength threshold may be set according to actual needs, for example, may be set by the first access network device.
也即是，该第一飞行设备切换至第一小区后，可以向该第一接入网设备反馈上报数据，该上报数据可以包括第一信号强度。如果该第一信号强度大于第一强度阈值，说明该第一接入网设备已经能够保证该第一飞行设备的通信质量，在该种情况下，该第一接入网设备可以向该第一飞行设备切换前所在的第二小区的第二接入网设备发送关闭指示，以指示该第二接入网设备关闭对该第二小区的网络覆盖。That is, after the first aircraft device switches to the first cell, it can feed back reporting data to the first access network device, and the reporting data may include the first signal strength. If the first signal strength is greater than the first strength threshold, it means that the first access network device can guarantee the communication quality of the first aircraft device. In this case, the first access network device can send a shutdown instruction to the second access network device of the second cell where the first aircraft device is located before the switch, so as to instruct the second access network device to shut down the network coverage of the second cell.
当然，在一些实施例中，该第二接入网设备在检测到第一飞行设备切换至第一小区，且第二小区内不存在接入该第二小区的其他飞行设备的情况下，可以自动关闭对该第二小区的网络覆盖，即不需要第一接入网设备指示关闭。Of course, in some embodiments, when the second access network device detects that the first flying device switches to the first cell and there are no other flying devices in the second cell that are connected to the second cell, the second access network device can automatically shut down the network coverage of the second cell, that is, the first access network device does not need to instruct to shut down.
进一步地，若第一小区中存在接入该第一小区的飞行设备，且该飞行设备飞向第三小区，则该第一接入网设备可以控制飞行设备进行切换，其具体实现可以包括如下步骤。Further, if there is an aerial device connected to the first cell in the first cell, and the aerial device flies to the third cell, the first access network device may control the aerial device to switch, and its specific implementation may include the following steps.
步骤1003：接收该第一小区内的飞行设备发送的上报数据，该上报数据包括第一信号强度和第二信号强度，该第一信号强度为对应的飞行设备在该第一小区内测量的信号强度，该第二信号强度为对应的飞行设备测量的第三小区的信号强度。Step 1003: Receive reporting data sent by the flight device in the first cell, the reporting data including a first signal strength and a second signal strength, the first signal strength being the signal strength measured by the corresponding flight device in the first cell, and the second signal strength being the signal strength of a third cell measured by the corresponding flight device.
作为一种示例，该第一小区内的飞行设备可能包括第一飞行设备。As an example, the flying devices in the first cell may include a first flying device.
作为一种示例，该上报数据还可以包括对应的飞行设备的地理位置信息，该地理位置信息可以包括经纬度信息和/或高度信息。As an example, the reported data may also include geographic location information of the corresponding flight equipment, and the geographic location information may include latitude and longitude information and/or altitude information.
其中，本申请中所述的第一小区内的飞行设备是指接入该第一小区的飞行设备，为了便于描述，下文直接描述为第一小区内的飞行设备。The flying equipment within the first cell mentioned in the present application refers to the flying equipment connected to the first cell. For the convenience of description, the following description is directly described as the flying equipment within the first cell.
该第一小区内的飞行设备可以向第一接入网设备发送上报数据，以告知第一接入网设备所测得的第一小区内的信号强度和第三小区的信号强度，即上报第一信号强度和第二信号强度，以便于该第一接入网设备确定该第一小区内是否存在需要切换的飞行设备。The flying device in the first cell can send reporting data to the first access network device to inform the first access network device of the signal strength measured in the first cell and the signal strength of the third cell, that is, report the first signal strength and the second signal strength, so that the first access network device determines whether there is a flying device that needs to be switched in the first cell.
步骤1004：若基于该第一小区内的飞行设备测量的第一信号强度和第二信号强度，确定该第一小区内的飞行设备中存在满足切换条件的第二飞行设备，控制该第二飞行设备向该第三小区切换。Step 1004: If it is determined that there is a second aerial device that meets the switching condition among the aerial devices in the first cell based on the first signal strength and the second signal strength measured by the aerial device in the first cell, the second aerial device is controlled to switch to the third cell.
作为一种示例，该第二飞行设备满足的切换条件包括：该第二飞行设备测量的第一信号强度小于第二强度阈值，且该第二飞行设备测量的第二信号强度大于第三强度阈值。As an example, the switching condition satisfied by the second flying device includes: a first signal strength measured by the second flying device is less than a second strength threshold, and a second signal strength measured by the second flying device is greater than a third strength threshold.
其中，该第二强度阈值和第三强度阈值均可以根据实际需求进行设置，并且，该第二强度阈值与该第三强度阈值可以相同，也可以不相同，本申请实施例对此不做限定。Among them, the second intensity threshold and the third intensity threshold can be set according to actual needs, and the second intensity threshold and the third intensity threshold can be the same or different, which is not limited in the embodiment of the present application.
如果该第一小区内的某飞行设备测得的第一信号强度低于第二强度阈值，而所得到的第二信号强度高于第三强度阈值，说明该飞行设备远离该第一小区，并已进入第三小区的覆盖范围，在该种情况下，可以确定该飞行设备为满足条件的第二飞行设备，此时，该第一接入网设备可以控制该第二飞行设备向该第三 小区进行切换。If the first signal strength measured by a certain flying device in the first cell is lower than the second strength threshold, and the obtained second signal strength is higher than the third strength threshold, it means that the flying device is away from the first cell and has entered the coverage of the third cell. In this case, it can be determined that the flying device is a second flying device that meets the conditions. At this time, the first access network device can control the second flying device to switch to the third cell.
作为一种示例，该第一小区内存在一个接入该第一小区的飞行设备，在该种情况下，确定第二飞行设备的具体实现可以包括：若根据该飞行设备的上报数据，确定该飞行设备飞离第一小区的小区中心且与该小区中心的距离大于第一指定距离阈值，将该飞行设备确定为该第二飞行设备。As an example, there is a flying device connected to the first cell within the first cell. In this case, the specific implementation of determining the second flying device may include: if it is determined based on the reported data of the flying device that the flying device has flown away from the cell center of the first cell and the distance from the cell center is greater than a first specified distance threshold, the flying device is determined as the second flying device.
其中，该第一指定距离阈值可以根据实际需求进行设置，通常情况下，该第一指定距离阈值与飞行设备的飞行高度有关，飞行高度越高，说明所在的小区的面积越大，不难理解，此时，该第一指定距离阈值就越大。也即是，针对不同飞行高度，可以设有不同的第一指定距离阈值。The first designated distance threshold can be set according to actual needs. Generally, the first designated distance threshold is related to the flight altitude of the aircraft. The higher the flight altitude, the larger the area of the cell. It is not difficult to understand that at this time, the first designated distance threshold is larger. That is, different first designated distance thresholds can be set for different flight altitudes.
不难理解，若该第一小区内仅包括一个飞行设备，则可以判断该飞行设备是否远离该第一小区的小区中心，如果确定该飞行设备远离该第一小区的小区中心，则可以将该飞行设备确定为满足切换条件的第二飞行设备。It is not difficult to understand that if the first cell includes only one flying device, it can be determined whether the flying device is far away from the cell center of the first cell. If it is determined that the flying device is far away from the cell center of the first cell, the flying device can be determined as a second flying device that meets the switching conditions.
根据该上报数据包括的内容不同，基于该上报数据确定该飞行设备远离该第一小区的小区中心的具体实现也不同。譬如，若该上报数据包括该飞行设备测量的信号强度，则在该信号强度持续低于一定阈值的情况下，确定该飞行设备飞离第一小区的小区中心，且与该第一小区的小区中心的距离大于第一指定距离阈值。或者，如果信号强度与距离之间存在预设的映射关系，则可以根据该飞行设备测量的信号强度，确定对应的距离，从而根据确定的距离，判断该飞行设备与该第一小区的小区中心的距离是否大于该第一指定距离阈值，然后，可以结合该飞行设备的地理位置信息的变化，判断该飞行设备是否是飞离第一小区的小区中心。Depending on the content included in the reported data, the specific implementation of determining that the flying device is far away from the cell center of the first cell based on the reported data is also different. For example, if the reported data includes the signal strength measured by the flying device, then when the signal strength continues to be lower than a certain threshold, it is determined that the flying device has flown away from the cell center of the first cell, and the distance from the cell center of the first cell is greater than the first specified distance threshold. Alternatively, if there is a preset mapping relationship between signal strength and distance, the corresponding distance can be determined based on the signal strength measured by the flying device, and then, based on the determined distance, it can be determined whether the distance between the flying device and the cell center of the first cell is greater than the first specified distance threshold, and then, combined with the change in the geographical location information of the flying device, it can be determined whether the flying device has flown away from the cell center of the first cell.
再如，若该上报数据包括该飞行设备的地理位置信息，则可以根据该地理位置信息确定飞行设备当前的位置与第一小区的小区中心的距离，从而确定该飞行设备是否远离该第一小区的小区中心，即确定该飞行设备是否飞离第一小区的小区中心，且与该第一小区的小区中心的距离是否大于第一指定距离阈值。For another example, if the reported data includes the geographic location information of the flying device, the distance between the current location of the flying device and the cell center of the first cell can be determined based on the geographic location information, thereby determining whether the flying device is far away from the cell center of the first cell, that is, determining whether the flying device has flown away from the cell center of the first cell and whether the distance to the cell center of the first cell is greater than a first specified distance threshold.
又如，若上报数据包括飞行设备的地理位置信息和信号强度，则该第一接入网设备可以基于该信号强度，结合地理位置信息，判断该飞行设备是否远离该第一小区的小区中心。For another example, if the reported data includes geographic location information and signal strength of the flying device, the first access network device may determine whether the flying device is far away from the cell center of the first cell based on the signal strength and the geographic location information.
需要说明的是，在控制第二飞行设备切换至第三小区之前，可以确定该第三小区。作为一种示例，若与该第一小区相邻的第三小区的数量仅包括一个，则可以直接确定第三小区。作为另一种示例，若与该第一小区相邻的第三小区的数量为多个，则该第一接入网设备可以根据第二飞行设备的地理位置信息确定第三小区，譬如，根据第二飞行设备的经纬度信息确定第三小区。It should be noted that before controlling the second flight device to switch to the third cell, the third cell may be determined. As an example, if the number of third cells adjacent to the first cell includes only one, the third cell may be directly determined. As another example, if the number of third cells adjacent to the first cell is multiple, the first access network device may determine the third cell according to the geographic location information of the second flight device, for example, determine the third cell according to the latitude and longitude information of the second flight device.
作为另一种示例，该第一小区内存在多个接入该第一小区的飞行设备，在该种情况下，确定第二飞行设备的具体实现可以包括：根据该多个飞行设备的上报数据，分别确定该多个飞行设备与该第一小区的小区中心的距离，从该多个飞行设备中确定与该小区中心的距离大于第二指定阈值的飞行设备，将所确定的飞行设备中飞离该小区中心且与该小区中心的距离最远的飞行设备确定为该第二飞行设备。As another example, there are multiple flying devices accessing the first cell. In this case, the specific implementation of determining the second flying device may include: determining the distances between the multiple flying devices and the cell center of the first cell respectively according to the reported data of the multiple flying devices, determining from the multiple flying devices a flying device whose distance from the cell center is greater than a second specified threshold, and determining the flying device among the determined flying devices that flies away from the cell center and is the farthest from the cell center as the second flying device.
其中，该第二指定阈值可以根据实际需求进行设置。通常情况下，该第二指定距离阈值与飞行设备的飞行高度有关，飞行高度越高，说明所在的小区的面积越大，不难理解，此时，该第二指定距离阈值就越大。也即是，针对不同飞行高度，可以设有不同的第二指定距离阈值。The second designated threshold value can be set according to actual needs. Generally, the second designated distance threshold value is related to the flight altitude of the flight device. The higher the flight altitude, the larger the area of the cell where the device is located. It is not difficult to understand that at this time, the second designated distance threshold value is larger. That is, different second designated distance threshold values can be set for different flight altitudes.
也就是说，若该第一小区内包括多个飞行设备，该第一接入网设备以第一个飞入第三小区的覆盖区域内的飞行设备为基准，即将该第一个飞入第三小区的覆盖区域内的飞行设备确定为第二飞行设备。That is to say, if the first cell includes multiple flying devices, the first access network device uses the first flying device that flies into the coverage area of the third cell as a reference, that is, determines the first flying device that flies into the coverage area of the third cell as the second flying device.
需要说明的是，在该种情况下，判断是否存在满足切换条件的第二飞行设备的方式与第一小区内存在一个接入第一小区的飞行设备时的判断方式相同。It should be noted that, in this case, the method of determining whether there is a second flying device that meets the switching condition is the same as the method of determining when there is a flying device that accesses the first cell in the first cell.
作为一种示例，该第三小区可能与上述第二小区相同，在该种情况下，该第一小区和第二小区均处于开启状态，第一接入网设备和第二接入网设备均通过窄波束，采用波束追踪的方式为各自小区内的飞行设备提供通信服务，如此，即使两个飞行设备在两个小区内采用了同样的资源，由于信号在空间实际并不重叠，从而构成了相互隔离，互不干扰。As an example, the third cell may be the same as the second cell mentioned above. In this case, the first cell and the second cell are both in an turned-on state, and the first access network device and the second access network device both provide communication services for the flying devices in their respective cells through narrow beams and beam tracking. In this way, even if the two flying devices use the same resources in the two cells, the signals do not actually overlap in space, thus constituting mutual isolation and non-interference.
进一步地，若该第一小区内的飞行设备切换至该第三小区，关闭该第一小区的网络覆盖。也就是说，若该第一小区内的飞行设备均切换至该第三小区内，则该第一接入网设备可以自动关闭该第一小区的网络覆盖。其中，若该第一小区内存在接入该第一小区的多个飞行设备，则该第一飞行设备在最后一个飞行设备飞离该第二小区后关闭。Further, if the flight equipment in the first cell switches to the third cell, the network coverage of the first cell is turned off. That is, if all the flight equipment in the first cell switches to the third cell, the first access network device can automatically turn off the network coverage of the first cell. If there are multiple flight equipments connected to the first cell in the first cell, the first flight equipment is turned off after the last flight equipment flies away from the second cell.
在另一实施例中，若该第一小区内的飞行设备切换至第三小区内，则该第一接入网设备在接收到第三接入网设备的关闭指示后，关闭对第一小区的网络覆盖。也即是，该第一接入网设备可以不自主关闭，而是在接收到关闭指示后再执行关闭操作。In another embodiment, if the flying device in the first cell switches to the third cell, the first access network device closes the network coverage of the first cell after receiving the closing instruction from the third access network device. That is, the first access network device may not close autonomously, but perform the closing operation after receiving the closing instruction.
进一步地，上报数据包括对应的飞行设备的地理位置信息，若基于该地理位置信息确定该第一小区内的飞行设备的飞行高度大于指定高度阈值，则根据该第一小区内的飞行设备的上报数据，判断该第一小区内是否存在满足切换条件的第二飞行设备。Furthermore, the reported data includes geographic location information of the corresponding flying device. If it is determined based on the geographic location information that the flight altitude of the flying device in the first cell is greater than a specified altitude threshold, then based on the reported data of the flying device in the first cell, it is determined whether there is a second flying device in the first cell that meets the switching conditions.
其中，该指定高度阈值可以根据实际需求进行设置。The specified height threshold can be set according to actual needs.
也即是，该第一接入网设备可以根据飞行设备的地理位置信息，确定该飞行设备当前的飞行高度，如 果该飞行高度大于指定高度阈值，可以认为该飞行设备所在的参考平面上各个小区之间存在大面积重叠，在该种情况下，执行上述提供的通信方法。That is, the first access network device can determine the current flight altitude of the flight device based on the geographic location information of the flight device. If the flight altitude is greater than the specified altitude threshold, it can be considered that there is a large overlap between the cells on the reference plane where the flight device is located. In this case, the communication method provided above is executed.
在本申请实施例中，第一接入网设备通过第一波束对第一小区进行网络覆盖，若第一飞行设备切换至该第一小区中，可以通过比该第一波束窄的第二波束，采用波束追踪的方式为该第一飞行设备提供通信服务。由于窄波束的信号强度要高于宽波束的信号强度，所以，即使第一小区与其他小区存在重叠，也可以保证第一飞行设备的SINR(Signal to Interference plus Noise Ratio，信号与干扰加噪声比)仍能保持在较高值，从而可以避免强干扰问题。In an embodiment of the present application, the first access network device provides network coverage for the first cell through the first beam. If the first flight device switches to the first cell, a second beam narrower than the first beam can be used to provide communication services for the first flight device by beam tracking. Since the signal strength of a narrow beam is higher than the signal strength of a wide beam, even if the first cell overlaps with other cells, the SINR (Signal to Interference plus Noise Ratio) of the first flight device can be maintained at a high value, thereby avoiding strong interference problems.
为了便于理解，接下来以几个具体示例对上述图10所示的实施例的实现过程进行举例说明。For ease of understanding, the implementation process of the embodiment shown in FIG. 10 is described below with reference to several specific examples.
示例一：请参考图11，小区1和小区2在一段时间内仅存在一个飞行设备，该飞行设备位于小区1内，且飞向小区2，该小区2处于未开启状态。Example 1: Please refer to FIG. 11 . There is only one aircraft in cell 1 and cell 2 within a period of time. The aircraft is located in cell 1 and flies to cell 2. Cell 2 is not turned on.
小区1在初始时刻采用大角度全面覆盖的方式来对该小区1所在区域进行覆盖，当飞行设备进入小区1的覆盖范围内并与地面基站1建立连接后，该地面基站1切换成窄波束，并采用波束追踪的方式来与飞行设备进行通信。At the initial moment, cell 1 uses a wide-angle full coverage method to cover the area where cell 1 is located. When the flying device enters the coverage range of cell 1 and establishes a connection with ground base station 1, the ground base station 1 switches to a narrow beam and uses beam tracking to communicate with the flying device.
在实施中，波束追踪的具体实现可以包括：飞行设备实时地将其经纬度信息等上报数据反馈给地面基站1，该地面基站1根据经纬度信息和反馈时间间隔，确定飞行设备的速度和方向，之后，根据该速度和方向，发射窄波束，从而实现波束追踪。其中，该反馈时间间隔是指当前反馈上报数据的时间点与上一次反馈上报数据的时间点之间的间隔。In practice, the specific implementation of beam tracking may include: the flight device feeds back its latitude and longitude information and other reported data to the ground base station 1 in real time, and the ground base station 1 determines the speed and direction of the flight device based on the latitude and longitude information and the feedback time interval, and then transmits a narrow beam based on the speed and direction, thereby achieving beam tracking. The feedback time interval refers to the interval between the time point of the current feedback report data and the time point of the last feedback report data.
当然，在另一实施例中，该飞行设备还可以直接将其飞行的速度和方向上报给地面基站1，以便于该地面基站1根据该速度和方向，发射窄波束，从而实现波束追踪。Of course, in another embodiment, the flying device can also directly report its flying speed and direction to the ground base station 1, so that the ground base station 1 can transmit a narrow beam according to the speed and direction, thereby realizing beam tracking.
小区1采用波束追踪的方式为飞行设备提供通信服务后，当飞行设备测量到地面基站1的信号强度低于门限1时，地面基站1通知地面基站2启动，地面基站2采用宽波束完成对小区2的覆盖，其时序如图12所示。After cell 1 provides communication services for the flying device by means of beam tracking, when the flying device measures that the signal strength of ground base station 1 is lower than threshold 1, ground base station 1 notifies ground base station 2 to start, and ground base station 2 uses a wide beam to complete coverage of cell 2. The timing is shown in FIG12 .
当飞行设备测量到地面基站1的信号强度持续低于门限2，且小区2的信号强度高于门限2时，地面基站1指示飞行设备向小区2切换。When the aircraft device measures that the signal strength of the ground base station 1 is continuously lower than the threshold 2 and the signal strength of the cell 2 is higher than the threshold 2, the ground base station 1 instructs the aircraft device to switch to the cell 2.
在完成切换后，地面基站2获得飞行设备的上报数据，并通过窄波束采用波束追踪的方式为飞行设备提供通信服务，其原理与地面基站1通过窄波束采用波束追踪的方式的原理相同。After the switching is completed, the ground base station 2 obtains the reported data of the flight equipment and provides communication services for the flight equipment through a narrow beam using beam tracking. The principle is the same as that of the ground base station 1 using a narrow beam using beam tracking.
当地面基站2根据飞行设备反馈的上报数据中的信号强度，确定其测量到的地面基站2的信号高于门限1时，地面基站2可以通知地面基站1关闭。When ground base station 2 determines that the signal of ground base station 2 measured by it is higher than threshold 1 according to the signal strength in the reported data fed back by the flight equipment, ground base station 2 can notify ground base station 1 to shut down.
或者，在另一实施例中，地面基站1也可以在确定飞行设备切换至小区2的情况下，自动关闭。Alternatively, in another embodiment, the ground base station 1 may also be automatically shut down when it is determined that the flying device switches to the cell 2 .
需要说明的是，在上述过程中，在重叠区域，在小区2打开前，该小区1可以保持基本无干扰的环境，飞行设备可以获得很好的通信质量。当小区2打开时，由于地面基站1采用的是窄波束为该飞行设备提供通信服务，该窄波束的信号强度要强于地面基站2的宽波束的信号强度，因此，即使小区2的系统广播信息与飞行设备在小区1中采用的资源重叠，也可以保证飞行设备当前的SINR仍能保持在较高值，不会发生强干扰问题。It should be noted that in the above process, in the overlapping area, before cell 2 is turned on, the cell 1 can maintain a basically interference-free environment, and the aircraft can obtain good communication quality. When cell 2 is turned on, since the ground base station 1 uses a narrow beam to provide communication services for the aircraft, the signal strength of the narrow beam is stronger than the signal strength of the wide beam of the ground base station 2. Therefore, even if the system broadcast information of cell 2 overlaps with the resources used by the aircraft in cell 1, it can ensure that the current SINR of the aircraft can still be maintained at a high value, and strong interference problems will not occur.
示例二：请参考图13，小区1内存在多个飞行设备，包括飞行设备1和飞行设备2，且飞向小区2，该小区2处于未开启状态。Example 2: Please refer to FIG. 13 . There are multiple aircrafts in cell 1, including aircraft 1 and aircraft 2, and they are flying towards cell 2, which is in an unactivated state.
小区1在初始时刻采用大角度全面覆盖的方式来对该小区1所在区域进行覆盖，当有飞行设备进入小区1的覆盖范围内并与地面基站1建立连接后，该地面基站1切换成窄波束，并采用波束追踪的方式来与飞行设备进行通信。At the initial moment, cell 1 uses a wide-angle full coverage method to cover the area where cell 1 is located. When a flying device enters the coverage range of cell 1 and establishes a connection with ground base station 1, the ground base station 1 switches to a narrow beam and uses beam tracking to communicate with the flying device.
在实施中，波束追踪的具体实现可以包括：飞行设备实时地将其经纬度信息等上报数据反馈给地面基站1，该地面基站1根据经纬度信息和反馈时间间隔，确定飞行设备的速度和方向，之后，根据该速度和方向，发射窄波束，从而实现波束追踪。其中，该反馈时间间隔是指当前反馈上报数据的时间点与上一次反馈上报数据的时间点之间的间隔。In practice, the specific implementation of beam tracking may include: the flight device feeds back its latitude and longitude information and other reported data to the ground base station 1 in real time, and the ground base station 1 determines the speed and direction of the flight device based on the latitude and longitude information and the feedback time interval, and then transmits a narrow beam based on the speed and direction, thereby achieving beam tracking. The feedback time interval refers to the interval between the time point of the current feedback report data and the time point of the last feedback report data.
当然，在另一实施例中，该飞行设备还可以直接将其飞行的速度和方向上报给地面基站1，以便于该地面基站1根据该速度和方向，发射窄波束，从而实现波束追踪。Of course, in another embodiment, the flying device can also directly report its flying speed and direction to the ground base station 1, so that the ground base station 1 can transmit a narrow beam according to the speed and direction, thereby realizing beam tracking.
小区1采用波束追踪的方式为飞行设备提供通信服务后，当确定飞行设备1测量的地面基站1的信号强度低于门限1时，地面基站1通知地面基站2启动，地面基站2采用宽波束完成对小区2的覆盖，其时序如图14所示。After cell 1 provides communication services for the flying device by means of beam tracking, when it is determined that the signal strength of ground base station 1 measured by flying device 1 is lower than threshold 1, ground base station 1 notifies ground base station 2 to start, and ground base station 2 uses a wide beam to complete coverage of cell 2. The timing is shown in FIG14 .
当飞行设备1测量到地面基站1的信号强度持续低于门限2，且小区2的信号强度高于门限2时，地面基站1指示飞行设备1向小区2切换。When the aircraft 1 measures that the signal strength of the ground base station 1 is continuously lower than the threshold 2 and the signal strength of the cell 2 is higher than the threshold 2 , the ground base station 1 instructs the aircraft 1 to switch to the cell 2 .
在完成切换后，地面基站2获得飞行设备1的上报数据，并通过窄波束采用波束追踪的方式为飞行设 备1提供通信服务，其原理与地面基站1通过窄波束采用波束追踪的方式的原理相同。After the switching is completed, the ground base station 2 obtains the reported data of the flight equipment 1, and provides communication services for the flight equipment 1 through a narrow beam using beam tracking. The principle is the same as that of the ground base station 1 using a narrow beam using beam tracking.
需要说明的是，在上述过程中，在重叠区域，在小区2打开前，该小区1可以保持基本无干扰的环境，飞行设备1可以获得很好的通信质量。当小区2打开时，由于地面基站1采用的是窄波束为该飞行设备1提供通信服务，该窄波束的信号强度要强于地面基站2的宽波束的信号强度，因此，即使小区2的系统广播信息与飞行设备1在小区1中采用的资源重叠，也可以保证飞行设备当前的SINR(Signal to Interference plus Noise Ratio，信号与干扰加噪声比)仍能保持在较高值，不会发生强干扰问题。It should be noted that in the above process, in the overlapping area, before the cell 2 is turned on, the cell 1 can maintain a basically interference-free environment, and the aircraft 1 can obtain good communication quality. When the cell 2 is turned on, since the ground base station 1 uses a narrow beam to provide communication services for the aircraft 1, the signal strength of the narrow beam is stronger than the signal strength of the wide beam of the ground base station 2. Therefore, even if the system broadcast information of the cell 2 overlaps with the resources used by the aircraft 1 in the cell 1, it can ensure that the current SINR (Signal to Interference plus Noise Ratio) of the aircraft can still be maintained at a high value, and strong interference problems will not occur.
在该种情况下，小区2的开启以首先进入小区2的飞行设备1为基准，小区1的关闭应以最后离开小区1的飞行设备2为基准。示例性地，该地面基站1可以在确定飞行设备2切换至小区2后自动关闭。In this case, the opening of cell 2 is based on the first aircraft device 1 entering cell 2, and the closing of cell 1 should be based on the last aircraft device 2 leaving cell 1. Exemplarily, the ground base station 1 can be automatically closed after determining that the aircraft device 2 switches to cell 2.
示例三：小区1和小区2都处于开启状态，小区1内存在至少一个飞行设备，且至少一个飞行设备飞向小区2，该小区2内存在至少一个飞行设备，且至少一个飞行设备飞向小区1，请参考图15，这里以该小区1内存在接入小区1的飞行设备1，小区2内存在接入小区2的飞行设备2为例进行举例说明。Example 3: Both cell 1 and cell 2 are in the on state, there is at least one flying device in cell 1, and at least one flying device flies to cell 2, there is at least one flying device in cell 2, and at least one flying device flies to cell 1. Please refer to Figure 15, where an example is given in which there is a flying device 1 in cell 1 that accesses cell 1, and there is a flying device 2 in cell 2 that accesses cell 2.
小区1在初始时刻采用大角度全面覆盖的方式来对该小区1所在区域进行覆盖，当飞行设备1进入小区1的覆盖范围内并与地面基站1建立连接后，该地面基站1切换成窄波束，并采用波束追踪的方式来与飞行设备1进行通信。At the initial moment, cell 1 uses a wide-angle full coverage method to cover the area where cell 1 is located. When the flying device 1 enters the coverage range of cell 1 and establishes a connection with the ground base station 1, the ground base station 1 switches to a narrow beam and uses beam tracking to communicate with the flying device 1.
同理，小区2在初始时刻采用大角度全面覆盖的方式来对该小区2所在区域进行覆盖，当飞行设备2进入小区2的覆盖范围内并与地面基站2建立连接后，该地面基站2切换成窄波束，并采用波束追踪的方式来与飞行设备2进行通信。Similarly, cell 2 initially uses a wide-angle full coverage method to cover the area where cell 2 is located. When the flying device 2 enters the coverage area of cell 2 and establishes a connection with the ground base station 2, the ground base station 2 switches to a narrow beam and uses beam tracking to communicate with the flying device 2.
以地面基站1采用波束追踪方式为飞行设备1提供通信服务为例，在实施中，波束追踪的具体实现可以包括：飞行设备1实时地将其经纬度信息等上报数据反馈给地面基站1，该地面基站1根据经纬度信息和反馈时间间隔，确定飞行设备1的速度和方向，之后，根据该速度和方向发射窄波束，从而实现波束追踪。其中，该反馈时间间隔是指当前反馈上报数据的时间点与上一次反馈上报数据的时间点之间的间隔。Taking the example of ground base station 1 providing communication services for flying device 1 by beam tracking, in practice, the specific implementation of beam tracking may include: flying device 1 feeds back its latitude and longitude information and other reported data to ground base station 1 in real time, and the ground base station 1 determines the speed and direction of flying device 1 according to the latitude and longitude information and feedback time interval, and then transmits a narrow beam according to the speed and direction, thereby implementing beam tracking. The feedback time interval refers to the interval between the time point of the current feedback reported data and the time point of the last feedback reported data.
当然，在另一实施例中，该飞行设备1还可以直接将其飞行的速度和方向上报给地面基站1，以便于该地面基站1根据该速度和方向发射窄波束，从而实现波束追踪。Of course, in another embodiment, the flying device 1 may also directly report its flying speed and direction to the ground base station 1, so that the ground base station 1 can transmit a narrow beam according to the speed and direction, thereby achieving beam tracking.
在上述实现方式中，各个小区均采用窄波束来提供通信服务，如此，即使两个飞行设备在两个小区内占用了同样的资源，由于信号在空间实际并不重叠，从而实现相互隔离，互不干扰。In the above implementation, each cell uses a narrow beam to provide communication services. In this way, even if two flying devices occupy the same resources in two cells, since the signals do not actually overlap in space, they are isolated from each other and do not interfere with each other.
进一步地，各个小区以窄波束提供通信服务后，如果检测到各自的飞行设备满足切换条件，可以与邻小区交互，以完成飞行设备的切换。以小区2内的飞行设备2的切换为例，小区2采用波束追踪的方式为飞行设备2提供通信服务后，当飞行设备2测量到地面基站2的信号强度持续低于门限2，且小区1的信号强度高于门限2时，地面基站2指示飞行设备2向小区1切换。Furthermore, after each cell provides communication services with a narrow beam, if it detects that its own aircraft meets the switching conditions, it can interact with the neighboring cell to complete the switching of the aircraft. Taking the switching of aircraft 2 in cell 2 as an example, after cell 2 provides communication services for aircraft 2 using beam tracking, when aircraft 2 measures that the signal strength of ground base station 2 is continuously lower than threshold 2, and the signal strength of cell 1 is higher than threshold 2, ground base station 2 instructs aircraft 2 to switch to cell 1.
在完成切换后，地面基站1获得飞行设备2的上报数据，并通过窄波束采用波束追踪的方式为飞行设备2提供通信服务，其原理与地面基站2通过窄波束采用波束追踪的方式的原理相同。After the switching is completed, the ground base station 1 obtains the reported data of the flight equipment 2, and provides communication services to the flight equipment 2 through a narrow beam using beam tracking. The principle is the same as that of the ground base station 2 using a narrow beam using beam tracking.
同理，小区1采用波束追踪的方式为飞行设备1提供通信服务后，当飞行设备1测量到地面基站1的信号强度持续低于门限2，且小区2的信号强度高于门限2时，地面基站1指示飞行设备1向小区2切换。在完成切换后，地面基站2获得飞行设备1的上报数据，并通过窄波束采用波束追踪的方式为飞行设备1提供通信服务。Similarly, after cell 1 provides communication services for aircraft 1 by beam tracking, when aircraft 1 measures that the signal strength of ground base station 1 is continuously lower than threshold 2, and the signal strength of cell 2 is higher than threshold 2, ground base station 1 instructs aircraft 1 to switch to cell 2. After the handover is completed, ground base station 2 obtains the reported data of aircraft 1 and provides communication services for aircraft 1 by beam tracking through narrow beams.
