控制网络设备及发送控制信息或数据的方法及装置 技术领域
本公开涉及通信技术领域，尤其涉及一种控制网络设备及发送控制信息或数据的方法及装置。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开以下实施例提供的技术方案可以应用于无线通信网络，例如：长期演进(long term evolution，简称为LTE)系统、先进的长期演进(long term evolution advanced，简称为LTE-A)系统，及其进一步的演进网络，例如5G网络。
无线通信网络中可以包括基站(base station，简称为BS)和用户设备(user equipment，简称为UE)。其中，基站可以是与用户设备或其它通信站点如中继站点，进行通信的设备。基站可以提供特定物理区域的通信覆盖。例如，基站具体可以LTE中的演进型基站(evolutional node B，简称为ENB或eNodeB)，或者，也可以是无线通信网络中的提供接入服务的其他接入网设备。
通常来说，无线通信网络可以包括网管系统，用于对基站进行功能配置。而对于分布式无线通信系统来说，基站分为主服务基站和从服务基站，主基站用于对从基站进行功能配置，从基站用于向主基站上报相关信息。
在本公开实施例中，UE可以为空中飞行的终端设备，例如：无人机。在整个无线网络中，空中飞行的终端设备可以分布于各个不同的空中区域。空中区域为高度等级区间或高度数值范围。
在具体实施时，空中区域可以是根据空中飞行的终端设备的飞行能力预先设定的，例如预先设定多个高度等级以及多个高度等级中每一高度等级的范围，则在获取到空中飞行的终端设备的位置信息后，判断该终端设备的位置处于哪一高度等级的范围，即可确定该终端设备处于哪一高度等级；也可以是在获取到空中飞行的终端设备的位置信息后，根据预定的粒度划分的空中区域，例如，划分粒度可以是10米，则垂直高度每10米为一个空中区域。
本公开实施例提供一种控制网络设备的方法，应用于控制设备，控制设备可以是网管系统，在此种情况下，被控设备(也即网络设备)为基站；或者，控制设备可以是主服务基站，在此种情况下，被控设备为从服务基站。请参考图1，图1是本公开实施例提供的一种控制网络设备的方法的流程图。如图1所示，该方法包括：
步骤S11：确定每一空中区域所对应的为该空中区域提供网络服务的网络设备集合；
步骤S12：向各个网络设备发送控制信息，所述控制信息用于指示在每一时间栅格上与该时间栅格对应的网络设备集合内的网络设备工作，且与该时间栅格对应的网络设备集合外的网络设备停止工作。
本公开实施例中，每一个空中区域均对应一个网络设备集合，一个空中区域所对应的网络设备集合是指：为该空中区域提供网络服务的网络设备集 合。
每一网络设备集合包括为对应的空中区域提供网络服务的网络设备的标识，可选地，每一网络设备集合中还包括该网络设备集合中每一网络设备上为该空中区域提供网络服务的波束序列的标识。
示例地，空中区域1对应的网络设备集合包括：网络设备1、网络设备2以及网络设备3，也就是说，网络设备1、网络设备2以及网络设备3均为空中区域1提供网络服务。又例如，空中区域1对应的网络设备集合包括：网络设备1+波束序列2，网络设备2+波束序列2，网络设备3+波束序列1。也就是说，网络设备1的波束序列2、网络设备2的波束序列2以及网络设备3的波束序列1均为空中区域1提供网络服务。
本公开实施例中，属于一个网络设备集合中的每一网络设备专门为对应的空中区域服务，即为对应的空中区域所专用，其他空中区域由其他网络设备集合提供网络服务。因此，对于一个网络设备而言，该网络设备仅为其所属的网络设备集合所对应的空中区域提供网络服务，而不对其他空中区域提供网络服务。
示例地，空中区域1对应的网络设备集合包括：网络设备1、网络设备2以及网络设备3，也就是说，网络设备1、网络设备2以及网络设备3均为空中区域1所专用，其他空中区域(例如空中区域2)由其他网络设备集合(例如网络设备集合2)提供网络服务。对于网络设备1而言，网络设备1仅为空中区域1提供网络服务，而不对其他空中区域(例如空中区域2)提供网络服务。
本公开实施例中，时间栅格是指固定长度的时间段。通过时域分割，将时间分割为多个时间栅格，每一时间栅格与一个空中区域所对应的网络设备集合相对应，也就是说，在一个时间栅格上，对应于该时间栅格的空中区域所对应的网络设备集合内的每一网络设备工作，其余网络设备停止工作。以 此实现将为不同空中区域提供网络服务的网络设备调度到不同的时间栅格中，避免了多个网络设备同时为各自所对应的空中区域提供网络服务而相互干扰，提高了网络质量。
示例地，图2为本公开实施例提供的一种时间栅格与网络设备集合之间的对应关系的示意图。如图2所示，时间栅格1对应为空中区域1提供网络服务的网络设备集合1，包括：网络设备1、网络设备2和网络设备3。因此，在时间栅格1上，网络设备1、网络设备2和网络设备3均工作(图2用阴影表示网络设备工作)，以便于为空中区域1提供网络服务，这样，位于空中区域1的终端设备就可以在时间栅格1上向网络设备1、网络设备2和网络设备3发送数据。并且，在时间栅格1上，网络设备4停止工作(图2用空白表示网络设备停止工作)，因此，网络设备4不会对网络设备1、网络设备2和网络设备3造成干扰，提高了网络质量。
可选地，一个时间栅格与一个空中区域所对应的网络设备集合之间的对应关系，可以按照如下方式确定：
根据位于每一空中区域的终端设备的业务请求数量和/或业务请求时延，将控制周期包括的各个时间栅格分别分配给各个空中区域各自所对应的网络设备集合。
可选地，一个控制周期中为该空中区域所对应的网络设备集合分配的时间栅格的数量与该空中区域的终端设备的业务请求数量成正比；或者，一个控制周期中为该空中区域所对应的网络设备集合分配的时间栅格的数量与该空中区域的终端设备的业务请求包含的最低业务时延数值成反比。
也就是说，位于一个空中区域的终端设备的业务请求数量越多和/或业务请求时延要求越高，一个控制周期中为该空中区域所对应的网络设备集合分配的时间栅格的数量越多。
例如，当位于某一空中区域的终端设备的业务请求数量或待调度传输数 据量较高时，则增加该高度等级对应的网络设备集合提供网络服务的时间栅格数；当位于某一个空中区域的终端设备的业务请求时延要求较高时，则增加该高度等级对应的网络设备集合提供网络服务的时间栅格数。
可选地，步骤S12有且不限于以下两种具体实施方式：
第一种实施方式包括以下步骤：
获取位于任一空中区域的终端设备对所述各个网络设备的接收功率，所述接收功率包括以下至少一种信号的接收功率：参考信号、同步信号、信道状态参考信号；将所述接收功率大于预设功率阈值的网络设备添加到候选网络设备集合；从所述候选网络设备集合中确定每一空中区域所对应的网络设备集合。
第二种实施方式包括以下步骤：
根据所述各个网络设备中每一网络设备和任一位置的终端设备之间的空间传播损耗模型，以及该网络设备和该终端设备之间的距离，确定该网络设备提供的网络服务的覆盖区域内任一位置的接收功率，所述接收功率包括以下至少一种信号的接收功率：参考信号、同步信号、信道状态参考信号；将所述接收功率大于预设功率阈值的网络设备添加到候选网络设备集合；从所述候选网络设备集合中确定每一空中区域所对应的网络设备集合。
参考信号、同步信号、信道状态参考信号的接收功率均在一定程度上反应了波束序列对终端设备的网络覆盖质量，在本公开实施例的一种可能的实现方式中，采用如下方式确定参考信号、同步信号、信道状态参考信号的接收功率：
网络设备初始启动时是所有波束序列全部打开，这样，任一空中区域的终端设备在检测到任一网络设备的任一波束序列的信号后，进行信道测量，并将测量得到的测量信息反馈给该网络设备，由该网络设备将测量信息发送给网管系统或者主服务基站。并且，网络设备在初始启动时，还可以将自身 所有波束序列的标识信息发送给网管系统或者主服务基站。
在本公开实施例的另一种可能的实现方式中，采用如下方式确定参考信号、同步信号、信道状态参考信号的接收功率：
通过网络规划仿真软件，可以控制每一网络设备发送参考信号、同步信号、信道状态参考信号，并利用该网络设备和任一位置的终端设备之间的空间传播损耗模型，计算其提供的网络服务的覆盖区域内任一位置的接收功率。
在确定参考信号、同步信号、信道状态参考信号的接收功率之后，可以预先设定参考信号、同步信号、信道状态参考信号中的一个或多个的接收功率阈值，在测量得到的接收功率大于对应的接收功率阈值时，将接收功率大于预设功率阈值的波束序列所属的网络设备添加到候选网络设备集合中，其中，候选网络设备集合在初始化时为空，即不包括任何网络设备。
最后，从候选网络设备集合中确定每一空中区域所对应的网络设备集合。
通过接收功率值的大小判断该网络设备是否属于任一空中区域所对应的网络设备集合，只是举例说明，在实际实施时，本公开实施例具体可以采用如下两种方式根据所述测量信息确定为每一空中区域提供网络服务的网络设备集合：
方式一、基于无缝覆盖原则，从所述候选网络设备集合中确定每一空中区域所对应的网络设备集合，其中，所述无缝覆盖原则是指每一空中区域内任一位置均有相应的网络设备提供的网络服务。
上述方式在保证网络质量的前提下，使得每一空中区域的任一位置均具有网络覆盖，保证了终端设备在每一空中区域的任一位置均可接入网络。
方式二、确定所述候选网络设备集合中每一网络设备提供的网络服务的覆盖区域；若所述候选网络设备集合中第一网络设备提供的网络服务的覆盖 区域覆盖第二网络设备提供的网络服务的覆盖区域，则从所述候选网络设备集合中删除所述第二网络设备，以得到最小化的网络设备集合；其中，所述第一网络设备和所述第二网络设备是所述候选集合中任两个不同的网络设备；从所述最小化的网络设备集合中确定每一空中区域所对应的网络设备集合。
上述方式可以得到最小化的网络设备集合，从而降低了网络设备的开销，减少了网络规划及终端设备移动带来的小区重选和切换，降低了管理复杂度。
值得说明的是，本公开实施例也可以将上述方式一和方式二结合起来确定每一空中区域所对应的网络设备集合。例如，在确定所述接收功率大于预设功率阈值的波束序列所属的网络设备，得到候选网络设备集合后，基于方式二，确定所述候选网络设备集合中每一网络设备提供的网络服务的覆盖区域，若所述候选网络设备集合中第一网络设备提供的网络服务的覆盖区域覆盖第二网络设备提供的网络服务的覆盖区域，则从所述候选网络设备集合中删除所述第二网络设备，以得到最小化的网络设备集合，进一步地，基于无缝覆盖原则，从所述最小化的网络设备集合中确定每一空中区域所对应的网络设备集合。也就是说，在实现无缝覆盖的前提下，使得为空中区域提供网络服务的网络设备数最少，在不影响网络服务的情况下，减少了网络设备的开销。
基于同一发明构思，本公开实施例还提供了一种发送控制信息的方法。该方法应用于被控设备，也即应用于网络设备。控制设备可以是网管系统，在此种情况下，被控设备(也即网络设备)为基站；或者，控制设备可以是主服务基站，在此种情况下，被控设备为从服务基站。请参考图3，图3是本公开实施例提供的一种发送控制信息的方法的流程图。如图3所示，该方法包括：
步骤S31：接收控制设备发送的控制信息，所述控制信息用于指示在每一时间栅格上所述网络设备工作或停止工作；
步骤S32：按照所述控制信息执行相应的操作，并将所述控制信息发送给终端设备。
在控制设备执行图1所示的方法之后，也即控制设备向各个网络设备发送控制信息之后，每一网络设备即可执行图3所示的方法。每一网络设备接收到控制设备发送的控制信息后，可以根据控制信息确定自身在当前时刻是否工作。对于一个网络设备而言，其在某些时间栅格上工作，以便为对应于这些时间栅格的空中区域提供网络服务，进而可以与位于这些时间栅格所对应的空中区域的终端设备进行数据传输。且对于该网络设备而言，在剩余时间栅格上停止工作，以避免对其他网络设备造成干扰。
以图2为例，假设时间栅格1对应于空中区域1所对应的网络设备集合(即网络设备集合1)，且假设时间栅格3对应于空中区域3所对应的网络设备集合(即网络设备集合3)。对网络设备1来说，其收到的控制信息是：在时间栅格1和时间栅格3上工作，且在时间栅格2上停止工作。如果当前时刻正好处于时间栅格1或时间栅格3上，则网络设备1工作，以便为空中区域1和空中区域3提供网络服务，进而可以与位于空中区域1和空中区域3的终端设备进行数据传输。如果当前时刻处于时间栅格2上，则网络设备1停止工作，以避免对网络设备2、网络设备3以及网络设备4造成干扰。
基于同一发明构思，本公开实施例还提供了一种发送数据的方法。该方法应用于终端设备，例如：在地面上的终端或在空中飞行的无人机。请参考图4，图4是本公开实施例提供的一种发送数据的方法的流程图。如图4所示，该方法包括以下步骤：
步骤S41：接收网络设备发送的控制信息，所述控制信息用于指示在每一时间栅格上所述网络设备工作或停止工作；
步骤S42：根据所述控制信息，在对应的时间栅格上向为所述终端设备所在的空中区域提供网络服务的终端设备发送数据。
在网络设备执行图3所示的方法之后，也即网络设备向终端设备发送控制信息之后，终端设备即可执行图4所示的方法。终端设备接收到网络设备发送的控制信息后，可以根据控制信息确定自身在什么时刻向哪个网络设备发送数据。由于网络设备仅在某些时间栅格上工作，且仅为某一空中区域专用，所以终端设备首先根据自身所在高度，确定自身对应的空中区域，然后再确定该空中区域所对应的网络设备集合以及相应的时间栅格，最后在所确定的时间栅格上向所确定的网络设备集合中的网络设备发送数据。以实现位于不同空中区域的终端设备在不同的时间栅格上向各自对应的网络设备发送数据。
以图2为例，假设时间栅格1对应于空中区域1所对应的网络设备集合(即网络设备集合1)，且假设时间栅格3对应于空中区域3所对应的网络设备集合(即网络设备集合3)。
终端设备1根据自身所在高度，确定自身对应空中区域1，由于时间栅格1对应于空中区域1，且空中区域1所对应的网络设备集合是网络设备集合1，包括：网络设备1、网络设备2、网络设备3，所以终端设备1可以在时间栅格1上向网络设备1、网络设备2、网络设备3中的一者或多者发送数据。而由于其他时间栅格对应其他空中区域所对应的网络设备集合，所以终端设备1不会在其他时间栅格上发送数据，避免了对其他终端设备造成干扰。
