本申请实施例中,对于任一无人机,若该无人机对应的终端簇数量为1,可以直接将该无人机对应的一个终端簇的聚类中心的位置信息,作为该无人机的第一位置信息。
步骤10221b,若无人机对应的终端簇数量大于1,根据无人机对应的多个终端簇各自对应的聚类中心的位置信息,确定多个终端簇对应的各聚类中心的几何中心的位置信息,并根据几何中心的位置信息,确定无人机的第一位置信息。
本申请实施例中,对于任一无人机,若该无人机对应的终端簇数量大于1,可以根据该无人机对应的所有终端簇对应的聚类中心的位置信息,确定各聚类中心的几何中心,以及将该几何中心的位置信息作为该无人机的第一位置信息,使得根据第一位置信息将无人机部署到几何中心后,无人机与对应的各终端簇内的用户终端的距离均小于第一距离阈值。由于第一距离阈值表征无人机的通信传播时延对应的距离阈值,因此,该无人机对应的各终端簇内的用户终端发送给无人机的数据所需的传输时间小于无人机的通信传播时延表征的传输时间,可以提高无人机的通信服务质量,一定程度上可以提高用户终端的通信质量。其中,几何中心的确认方式可以参考步骤10221中的相关描述,此处不再赘述。
在本申请实施例中,通过对于任一无人机,若无人机对应的终端簇为1,根据无人机对应的终端簇对应的聚类中心的位置信息,确定无人机的第一位置信息;若无人机对应的终端簇数量大于1,根据无人机对应的多个终端簇各自对应的聚类中心的位置信息,确定多个终端簇对应的各聚类中心的几何中心的位置信息,并根据几何中心的位置信息,确定无人机的第一位置信息。这样,根据无人机对应的终端簇的数量是否大于1进行区分处理,可以提高各无人机的第一位置信息的获取效率,一定程度上可以提高本申请的通信设备部署方法的部署效率。
可选的,步骤1023可以包括以下步骤:
步骤10231,根据各无人机对应的终端簇的位置重要性参数和终端簇负载,确定各无人机对应的终端簇的期望负载参数。
本申请实施例中,位置重要性参数可以表征终端簇内的用户终端所处区域的位置重要程度。例如,学校、居民区、医院等人口密集区域的位置更重要,相应的人口密集区域的用户终端对应的终端簇的位置重要性参数大,而人烟较为稀少的郊区等区域位置相对不重要,相应的人口稀少区域的用户终端对应的终端簇的位置重要性参数小。其中,任一终端簇的位置重要性参数可以根据该终端簇内的用户终端所处区域的位置重要程度预先定义,例如,若该终端簇内的用户终端处于人口密集区域,则可以将该终端簇的位置重要性参数定义为100,若该终端簇内的用户终端处于人口稀少区域,则可以将该终端簇的位置重要性参数定义为10,从而通过位置重要性参数衡量终端簇内用户终端所处区域的位置重要程度。此处仅是举例说明,本申请实施例对此不做限制。
本申请实施例中,可以根据各无人机对应的终端簇的位置重要性参数、终端簇负载及各自的权重系数,确定各无人机对应的终端簇的期望负载参数。具体的,可以参照以下公式计算任一终端簇的期望负载参数:
Ri=βLi+(1-β)li (7)
Ri=βLi+(1-β)li (7)
其中,Ri表示第i个终端簇的期望负载参数,Li表示第i个终端簇的位置重要性参数,li表示第i个终端簇的终端簇负载,β和(1-β)分别表示第i个终端簇的位置重要性参数和终端簇负载各自的权重系数。对于任一无人机,可以参照公式(7)计算该无人机对应的终端簇各自的期望负载参数,然后根据该无人机对应的终端簇各自的期望负载参数确定该无人机对应的终端簇的期望负载参数。其中,若无人机只对应一个终端簇,则可以将该终端簇的期望负载参数作为该无人机对应的终端簇的期望负载参数,若无人机对应多个终端簇,则可以将多个终端簇的期望负载参数的数值相加,将相加结果作为该无人机对应的终
端簇的期望负载参数。
步骤10232,根据各无人机的第一位置信息,确定各无人机之间的距离。
本申请实施例中,第一位置信息可以包括各无人机待部署位置的经纬度信息和海拔高度,可以根据经纬度信息和海拔高度计算各无人机之间的距离,具体的计算方式可以参考现有技术中的计算方式,此处不再赘述。
步骤10233,根据各无人机之间的距离、各无人机对应的终端簇的期望负载参数及各处理设备的最大可供负载,确定各无人机对应的处理设备的第二位置信息;无人机对应的处理设备与无人机的距离小于第二距离阈值,无人机对应的终端簇负载小于无人机对应的处理设备的最大可供负载。
本申请实施例中,第二距离阈值表征处理设备的通信传播时延对应的距离阈值,即超过该距离阈值的无人机发送给处理设备的数据所需的传输时间超过处理设备的通信传播时延表征的传输时间。其中,第二距离阈值可以根据处理设备的通信传播时延和通信数据的传播速度计算获得。对于任一处理设备,可以根据该处理设备的最大可供负载和各无人机对应的终端簇的期望负载参数,确定该处理设备对应的备选无人机。其中,所有备选无人机对应的终端簇的终端簇负载总和小于处理设备的最大可供负载,终端簇负载总和可以将各备选无人机对应的终端簇的终端簇负载相加得到。然后,根据各备选无人机之间的距离确定所有备选无人机所处位置的几何中心,其中,可以根据各备选无人机之间的距离确定一个可以覆盖所有备选无人机的几何图形,然后计算几何图形的几何中心,以及将几何图形的几何中心作为所有备选无人机所处位置的几何中心。然后,按照各备选无人机对应的终端簇负载递减的顺序,验证各备选无人机与几何中心的距离是否小于第二距离阈值,若符合验证条件则该备选无人机可以确定为该处理设备对应的无人机,否则停止验证,并将符合验证条件的备选无人机作为该处理设备对应的无人机,以及基于符合验证条件的备选无人机之间的距离确定最终几何中心,以及将最终几何中心的位置信息作为该处理设备的第二位置信息。其中,该处理设备最终确定的对应无人机满足该处理设备与无人机的距离小于第二距离阈值,无人机对应的终端簇负载小于无人机对应的处理设备的最大可供负载的限制条件,使得处理设备不过载,且处理设备与所覆盖的无人机的数据传输延迟时间符合该处理设备的通信传播时延的要求。
在本申请实施例中,通过根据各无人机对应的终端簇的位置重要性参数和终端簇负载,确定各无人机对应的终端簇的期望负载参数;根据各无人机的第一位置信息,确定各无人机之间的距离;根据各无人机之间的距离、各无人机对应的终端簇的期望负载参数及各处理设备的最大可供负载,确定各无人机对应的处理设备的第二位置信息。这样,可以通过位置重要性参数调整不同位置重要程度的终端簇的期望负载参数,使得根据期望负载参数确定的处理设备的第二位置信息与终端簇的位置重要程度更加匹配,提高本申请的通信设备部署方法的实用性。且由于无人机对应的处理设备与无人机的距离小于第二距离阈值,无人机对应的终端簇负载小于无人机对应的处理设备的最大可供负载,可以使得无人机与对应的处理设备进行数据传输时的通信距离控制在一定范围内,且处理设备的实际工作负载不超过处理设备的最大可供负载,从而提高处理设备的通信服务质量,一定程度上可以提高用户终端的通信质量。
