附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
本发明实施例提供一种信号覆盖的方法，如图1所示，包括：
101、获取缺失基站每个缺失扇区的扇区覆盖范围。
其中，所述缺失基站是指由于城市建设和站址物业合约到期等原因无法使用的基站。而缺失扇区就是指缺失基站在正常工作时使用的扇区。
102、从所述缺失基站附近的基站中，为每个缺失扇区分别选取各自对应的补偿基站。
由于每个基站通常都会设置至少三个扇区来覆盖自身所要服务的区域，因此，当基站不工作时，就会产生多个空白的扇区区域，若想弥补缺失空白扇区区域的话，就要为每个扇区都选取一个补偿基站，并以补偿基站的信号覆盖这些空白扇区。
在本发明实施例中，补偿基站的选择需要遵循以下原则，包括：
1、每个缺失扇区各自对应的补偿基站的至少一个补偿扇区的扇区覆盖范围与缺失扇区自身的扇区覆盖范围存在交叠。所述补偿扇区为所述补偿基站的所有扇区中的一个。
也就是说，补偿基站在正常工作状态下就能够一定程度上覆盖缺失扇区的一部分，在此基础上进一步调整补偿基站的天线设置就可以完成缺失扇区的全覆盖，具体调整方法可参照后续描述。
2、所述补偿基站为所述缺失基站附近的基站中与所述缺失基站距离最近的并处于正常工作状态的基站之一。
优选距离最近的基站可以进一步方便天线设置的调整。
103、调整所述补偿基站的补偿扇区对应的天线配置，以使得所述补偿扇区的信号能够覆盖所述缺失基站的至少一个缺失扇区内的所有用户设备。
需要说明的是，该步骤的执行是需要对每个缺失扇区所对应的补偿基站进行调整的，但是对被调整的补偿基站来说，并不是该补偿基站的所有扇区的天线都要进行调整，而是只调整补偿扇区的天线。
本发明实施例提供的一种信号覆盖的方法，通过选取补偿基站，并调整补偿扇区的天线配置以完成补偿扇区的信号能够覆盖所述缺失基站的至少一个缺失扇区内的所有用户设备，使得补偿基站能够为无服务区域提供原有服务，从而解决了基站缺少造成的覆盖范围空白，提高了覆盖程度，增加了移动网络系统容量。
进一步的，本发明实施例对于如何调整补偿基站的补偿扇区对应的天线配置，即如何执行步骤103，提供了以下两种实现方法，具体为：
第一种实现方法：将所述补偿基站的补偿扇区对应的单天线替换为双天线。如图2所示，其具体流程为：
A1031、获取所述补偿扇区覆盖的缺失扇区的覆盖范围和扇区容量，以及，补偿扇区的原始覆盖范围和原始扇区容量。
其中，缺失扇区的覆盖范围一般使用缺失扇区所覆盖的小区边缘容量的概率分布函数的第5个百分点的值进行衡量；而扇区容量则使用缺失扇区所覆盖的小区平均容量的概率分布函数的第50个百分点的值进行衡量。
补偿扇区的原始覆盖范围和原始扇区容量使用同样的衡量方法。
A1032、根据所述补偿扇区覆盖的缺失扇区的覆盖范围和扇区容量，设置第一补偿天线的下倾角和发射功率。
其中，第一补偿天线的下倾角一般由覆盖范围决定，第一补偿天线的发射功率一般由扇区容量决定，当然第一补偿天线的下倾角和发射功率也可以参考其他的参数进行设定。在设定好之后可以根据仿真或实地测量进行进一步的调整。
这样设置之后，第一补偿天线就可以用于将基站信号覆盖至缺失的区域。
A1033、根据所述补偿扇区的原始覆盖范围和原始扇区容量，设置第二补偿天线的下倾角和发射功率。
第二补偿天线的下倾角和发射功率的设置方法与第一补偿天线的下倾角和发射功率的设置方法是类似的，本发明对此不再赘述。
这样设置之后，第二补偿天线就可以用于将基站信号覆盖至补偿基站原本应该覆盖的区域。
但是在本实施方式中有一点需要注意的是，所述第一补偿天线的扇区方向、所述第二补偿天线的扇区方向与所述单天线的扇区方向相同。
在本实施方式中，第一补偿天线可以使用补偿扇区原有天线，而第二补偿天线需要使用下倾角调整幅度在20°以上的大下倾天线。并且，由于本实施方式中使用了两根天线，因此相应的需要设置两个RRU，考虑到基站的硬件配置，在本实施方式中两个RRU的发射总功率一般不能超过原单天线对应的RRU的发射功率。
以上为步骤103的第一种实现方法，以下为第二种实现方法。
第二种实现方法：将所述补偿基站的补偿扇区对应的单天线替换为垂直劈裂波束天线。垂直劈裂波束天线可以理解为将两根天线合并到一起使用的一根天线，虽然对外呈现的效果是一根天线，但是实际使用时是可以当作两根虚拟的天线进行使用的，在本实施方式中，虚拟出的两根天线分别称为第一补偿天线模块和第二补偿天线模块。
如图3所示，其具体流程为：
B1031、获取所述补偿扇区覆盖的缺失扇区的覆盖范围和扇区容量，以及，补偿扇区的原始覆盖范围和原始扇区容量。
其中，所述补偿扇区覆盖的缺失扇区的覆盖范围和扇区容量，以及，补偿扇区的原始覆盖范围和原始扇区容量的衡量方法与第一种实现方式中是相同的，在此不多做描述。
B1032、根据所述补偿扇区覆盖的缺失扇区的覆盖范围和扇区容量，设置所述垂直劈裂波束天线的第一补偿天线模块的下倾角和发射功率。
这样设置之后，第一补偿天线模块就可以用于将基站信号覆盖至缺失的区域。
B1033、根据所述补偿扇区的原始覆盖范围和原始扇区容量，设置所述垂直劈裂波束天线的第二补偿天线模块的下倾角和发射功率。
这样设置之后，第二补偿天线模块就可以用于将基站信号覆盖至补偿基站原本应该覆盖的区域。
在本实施方式中需要注意的一点是，所述垂直劈裂波束天线的扇区方向与所述单天线的扇区方向相同。
在以上两种实现方式中，通过使用双天线或者是由垂直劈裂波束天线虚拟出的两根天线，以实现对缺失扇区的信号覆盖，同时也保证了补偿基站原本应该覆盖范围内的信号质量，从而实现了全区域覆盖，保证了用户设备在任何位置都能接入基站得到服务。
本发明实施例还提供了一种信号覆盖的装置，如图4所示，该控制包括：
