在实现本发明的过程中，发明人发现现有技术至少存在以下问题：
Femto基站只是单纯根据邻近小区的情况对自身进行配置，以避免与邻近小区之间产生干扰，然而，在避免与邻近小区的干扰的情况下有可能会导致与之通信的UE的通信质量差，达不到自动调整要求的效果。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
下面先结合图1简单介绍一下本发明实施例提供的基站自动调整方法的应用场景。参见图1，一片区域布置有基站a、基站b、基站c、基站d、基站e和基站f(图中用方形表示基站，以方形为圆心的圆形区域为基站的覆盖区域)，分别为覆盖区域内的用户设备(User Equipment，简称UE)提供通信服务。UE 1、UE 2在基站a的覆盖区域内，UE 2、UE 3、UE 4、UE 5、UE 6在基站b的覆盖区域内，UE 3、UE 4、UE 7、UE 8、UE 9在基站c的覆盖区域内，UE 4、UE 6、UE 7、UE 10、UE 11、UE 12、UE 13、UE 14在基站d的覆盖区域内，UE 11、UE 12、UE 13、UE 15、UE 16在基站e的覆盖范围内，UE 13、UE 14、UE 15、UE 17在基站f的覆盖范围内。
位于基站的覆盖范围内的UE可以检测到基站发送的参考信号，并向基站 上报测量报告，测量报告包括UE检测到的所有基站的参考信号接收功率(Reference Signal Receiving Power，简称RSRP)，因此基站可以根据UE的测量报告确定覆盖范围重叠的基站，即相邻基站。以图1为例，UE 1的测量报告包括基站a的RSRP，UE 2的测量报告包括基站a、基站b的RSRP，UE 3的测量报告包括基站b、基站c的RSRP，UE 4的测量报告包括基站b、基站c、基站d的RSRP，UE 5的测量报告包括基站b的RSRP，UE 6的测量报告包括基站b、基站d的RSRP，UE 7的测量报告包括基站c、基站d的RSRP，UE 8的测量报告包括基站c的RSRP，UE 9的测量报告包括基站c的RSRP，UE 10的测量报告包括基站d的RSRP，UE 11的测量报告包括基站d、基站e的RSRP，UE 12的测量报告包括基站d、基站e的RSRP，UE 13的测量报告包括基站d、基站e、基站f的RSRP，UE 14的测量报告包括基站d、基站f的RSRP，UE 15的测量报告包括基站e、基站f的RSRP，UE 16的测量报告包括基站e的RSRP，UE 17的测量报告包括基站f的RSRP。
基站a根据UE 1、UE 2的测量报告确定相邻基站为基站b，基站b根据UE 2、UE 3、UE 4、UE 5、UE 6的测量报告确定相邻基站为基站a、基站c、基站d，基站c根据UE 3、UE 4、UE 7、UE 8、UE 9的测量报告确定相邻基站为基站b、基站d，基站d根据UE 4、UE 6、UE 7、UE 10、UE 11、UE 12、UE 13、UE 14的测量报告确定相邻基站为基站b、基站c、基站e、基站f，基站e根据UE 11、UE 12、UE 13、UE 15、UE 16的测量报告确定相邻基站为基站d、基站f，基站f根据UE 13、UE 14、UE 15、UE 17的测量报告确定相邻基站为基站d、基站e。
各个基站将其相邻基站汇总到基站上层的主控(master)或者其中一个基站，由得到各个基站的相邻基站的master或基站确定遍历的起始节点，并采用集中式或分布式的方式遍历所有的基站，从而确定各个基站之间的树形关系。其中，遍历的起始节点优选为相邻基站数量最多的基站，也可以任意选择一个。
当采用集中式的方式遍历时，假设以基站b为起始节点，master对应基站b标识已遍历、次数为1；从基站b的相邻基站中选择未遍历的基站d，对应基站d标识基站b为父基站、已遍历、次数为2，对应基站b标识基站d为子基站；从基站d的相邻基站中选择未遍历的基站e，对应基站e标识基站d为父基站、已遍历、次数为3，对应基站d标识基站e为子基站；从基站e的相邻基站中选择未遍历的基站f，对应基站f标识基站e为父基站、已遍历、次数 为4，对应基站e标识基站f为子基站；基站f未标识的相邻基站d已遍历，对应基站f标识基站d为祖先基站，对应基站d标识基站f为子孙基站；基站f没有未遍历的相邻基站，沿遍历路径返回直到存在未遍历的相邻基站的基站d；从基站d的相邻基站中选择未遍历的基站c，对应基站c标识基站d为父基站、已遍历、次数为5，对应基站d标识基站c为子基站；基站c未标识的相邻基站b已遍历，对应基站c标识基站b为祖先基站，对应基站b标识基站c为子孙基站；基站c没有未遍历的相邻基站，沿遍历路径返回到基站b；从基站b的相邻基站中选择未遍历的基站a，对应基站a标识基站b为父基站，对应基站b标识基站a为子基站；基站a没有未遍历的相邻基站，沿遍历路径返回到基站b，起始节点基站b没有未遍历的相邻基站，遍历结束，得到图2所示的所有基站之间的树形关系，树形关系包括各个基站与相邻基站之间的关系(粗线表示父子关系，细线表示祖孙关系)；将对应各个基站标识的与相邻基站的关系反馈给各个基站。需要说明的是，选择未遍历的基站时，可以优选相邻基站数量最多的基站。
当采用分布式的方式遍历时，还是假设基站b为起始节点，基站b标识已遍历、次数为1；基站b从相邻基站中选择基站d并向基站d发送消息，基站d接收消息后标识基站b为父基站、已遍历、次数为2；基站d从相邻基站中选择基站e并向基站e发送消息，基站e接收消息后标识基站d为父基站、已遍历、次数为3；基站e从相邻基站中选择基站f并向基站f发送消息，基站f接收消息后标识基站e为父基站、已遍历、次数为4；基站f从相邻基站中选择基站d并向基站d发送消息，基站d接收消息后标识基站f为子孙基站并向基站f反馈消息，基站f接收消息后标识基站d为祖先基站；基站f没有未遍历的相邻基站，向基站e反馈消息，基站e接收消息后标识基站f为子基站；基站e没有未遍历的相邻基站，向基站d反馈消息，基站d接收消息后标识基站e为子基站；基站d从相邻基站中选择基站c并向基站c发送消息，基站c接收消息后标识基站d为父基站、已遍历、次数为5；基站c从相邻基站中选择基站b并向基站b发送消息，基站b接收消息后标识基站c为子孙基站并向基站c反馈消息，基站c接收消息后标识基站b为祖先基站；基站c没有未遍历的相邻基站，向基站d反馈消息，基站d接收消息后标识基站c为子基站；基站d没有未遍历的相邻基站，向基站b反馈消息，基站b接收消息后标识基站d为子基站；基站b从相邻基站中选择基站a并向基站a发送消息，基站a 接收消息后标识基站b为父基站；基站a没有未遍历的相邻基站，向基站b反馈消息，基站b接收消息后标识基站a为子基站；起始节点基站b没有未遍历的相邻基站，遍历结束，各个基站可以得到图2所示的所有基站之间的树形关系中有关各自相邻基站的部分。
上述树形关系在基站建立初期形成，在后期运行过程中基本不变。若后期加入新基站，或者减少已有基站，也只是对变动基站的相邻基站的树形关系作出相应变化。
需要说明的是，图1和图2中的基站和UE的数量、位置等仅为举例，本发明并不限制于此。并且，本发明所涉及到的用户设备可以包括具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的移动台(Mobile station，简称MS)，终端设备(Terminal Equipment)等等。
具体地，实现本发明实施例提供的基站自动调整方法的基站结构可以如图3所示。如图3所示，基站200可以包括多根天线210、射频模块220(射频拉远单元(Radio Remote Unit，简称RRU)或者(射频单元(Radio Frequency Unit，简称RFU))、基带单元(Building Base band Unit，简称BBU)230。基带单元230包括存储器231和处理器232。图3示出的基站200结构并不构成对基站200的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
处理器232是基站200的控制中心，利用各种接口和线路连接整个基站200的各个部分，通过运行或执行存储在存储器231内的软件程序和/或模块，以及调用存储在存储器231内的数据，执行基站200的各种功能和处理数据，从而对基站200进行整体控制。可选的，处理器232可包括一个或多个处理核心。
存储器231可用于存储各种数据，例如各种配置参数，以及存储软件程序以及模块。处理器232通过运行存储在存储器231的软件程序以及模块，从而执行各种功能应用以及数据处理。存储器231可主要包括程序存储区和数据存储区，其中，程序存储区可存储操作系统231a、报告接收模块231b、确定模块231c、参数发送模块231d、数量接收模块231e、调整模块231f、参数接收模块231g等；存储数据区可存储根据基站2的使用所创建的数据，例如RF参数、UE数量等。此外，存储器231可以由任何类型的易失性或非易失性存 储设备或者它们的组合实现，如静态随机存取存储器(Static Random Access Memory，简称SRAM)，电可擦除可编程只读存储器(Electrically Erasable Programmable Read-Only Memory，简称EEPROM)，可擦除可编程只读存储器(Erasable Programmable Read Only Memory，简称EPROM)，可编程只读存储器(Programmable Read-Only Memory，简称PROM)，只读存储器(Read Only Memory，简称ROM)，磁存储器，快闪存储器，磁盘或光盘。相应地，存储器231还可以包括存储器控制器，以提供处理器232对存储器231的访问。
BBU 230通过与射频模块220连接，射频模块220通过电缆与天线210连接。在下行链路方向，BBU 230输出基带信号至射频模块220。射频模块220将基带信号变频到中频信号，再将中频信号变频到射频信号，然后采用功放单元(例如射频功率放大器)将射频信号放大，最后将放大后的射频信号通过天线210发射出去。在上行链路方向，来自终端的射频信号经天线210传递至射频模块220。射频模块220先将射频信号放大，再变频到中频信号，接着变频到基带信号，然后将基带信号输出至BBU 230。
本发明实施例提供了一种基站自动调整方法，参见图4，该方法包括：
步骤301：第一基站上电，按照设定的射频参数运行。
在本实施例中，第一基站为前述树形关系中的一个节点，即具有覆盖范围与第一基站的覆盖范围重叠的相邻基站，相邻基站包括第一基站的父基站、子基站、祖先基站、子孙基站中的至少一种。
在实际应用中，基站上电后会先按照设定的射频(Radio Frequency，简称RF)参数(如基站的最大发射功率、天线的最小下倾角)运行，后续再根据UE的通信质量进行调整。同时基站还会向相邻基站发送消息，进行注册，告知相邻基站本基站的存在。
可选地，RF参数可以包括基站的发射功率、天线下倾角、天线方向角中的至少一种。
步骤302：第一基站接收覆盖范围内所有UE上报的测量报告。
在本实施例中，各个UE上报的测量报告包括各自检测到的所有基站发送的参考信号的参考信号接收功率(Reference Signal Receiving Power，简称RSRP)。
在实际应用中，基站会向位于其覆盖范围内的所有UE发送携带有其标识 的参考信号，如小区特定参考信号(Cell-specific Reference Signals，简称CRS)、信道状态指示参考信号(Channel State Information Reference Signals，简称CSI-RS)等。各个UE将接收到各个基站发送的参考信号时的功率(即各个基站发送的参考信号的RSRP)、以及参考信号的发送基站的标识，并将各个基站的标识及RSRP一起作为测量报告发送给各个基站。基站接收到测量报告后，可以根据自身标识从中找到自己的RSRP，同时根据自己的RSRP和其它基站的RSRP确定自己的信号与干扰加信噪比(Signal to Interference plus Noise Ratio，简称SINR)，进而以RSRP和SINR评价UE的通信质量。
可选地，该步骤302可以包括：
第一基站每隔设定时间接收覆盖范围内所有UE上报的测量报告。
在实际应用中，UE的位置是时时变化的，UE接收的参考信号及其功率都会变化，因此基站通常会每隔设定时间发送参考信号，同时UE也会每隔设定时间上报测量报告，以及时更新UE的通信质量。
步骤303：第一基站根据测量报告确定第一基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量。
在本实施例的一种实现方式中，该步骤303可以包括：
第一基站根据各个UE上报的测量报告，确定各个UE接收第一基站发送的参考信号的RSRP；
第一基站统计接收第一基站发送的参考信号的RSRP小于设定的功率阈值的UE数量，并将统计的UE数量作为第一基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量。
在本实施例的另一种实现方式中，该步骤303还可以包括：
第一基站根据各个UE上报的测量报告，确定各个UE接收各个基站发送的参考信号的RSRP；
第一基站根据各个UE接收各个基站发送的参考信号的RSRP，计算各个UE接收第一基站发送的参考信号的SINR；
第一基站统计第一基站发送的参考信号的SINR小于设定的信噪比阈值的UE数量，并将统计的UE数量作为第一基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量。
具体地，第一基站根据各个UE接收各个基站发送的参考信号的RSRP，计算各个UE接收第一基站发送的参考信号的SINR，可以包括：
第一基站根据各个UE接收第一基站发送的参考信号的RSRP、以及除第一基站之外的其它基站发送的参考信号的RSRP，得到各个UE接收第一基站发送的参考信号的SINR。
例如，可以将UE接收第一基站发送的参考信号的RSRP除以除第一基站之外的其它基站发送的参考信号的RSRP与底噪之和，作为UE接收第一基站发送的参考信号的SINR。
在本实施例的又一种实现方式中，该步骤303可以包括：
第一基站根据UE上报的测量报告，确定UE接收各个基站发送的参考信号的RSRP；
第一基站根据UE接收各个基站发送的参考信号的RSRP，计算UE接收第一基站发送的参考信号的SINR；
第一基站统计接收第一基站发送的参考信号的RSRP小于设定的功率阈值且SINR小于设定的信噪比阈值的UE数量之和，并将统计的UE数量作为第一基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量。
步骤304：当第一基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量大于或等于设定的调整启动阈值时，第一基站根据测量报告确定第一基站的待调整RF参数，并估计第一基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量。
在本实施例中，通信质量参数可以包括RSRP、SINR中的至少一种。当通信质量参数包括RSRP时，参数阈值包括功率阈值；当通信质量参数包括SINR时，参数阈值包括信噪比阈值。
在本实施例的一种实现方式中，该步骤304可以包括：
第一基站选择不同的取值代入如下公式(1)估计第一基站的RF参数调整为不同取值时各个UE接收第一基站发送的参考信号的RSRP：
RSRP_new＝RSRP_old-Rxpower_old+Rxpower_new；(1)
其中，RSRP_new为基站的发射功率调整为待调整RF参数时基站发送的参考信号的RSRP，RSRP_old为基站当前发送的参考信号的RSRP，Rxpower_old为基站当前的发射功率，Rxpower_new为基站的待调整RF参数中的发射功率；
当接收第一基站发送的参考信号的RSRP大于或等于功率阈值的UE数量小于调整启动阈值时，第一基站将对应的取值作为第一基站的待调整RF参数。
需要说明的是，当RF参数包括基站的发射功率时，可以直接采用上述方式实现。当RF参数包括天线下倾角时，也可以利用上述方式实现，比如以基站的覆盖范围不变为标准，建立基站的发射功率和基站的天线下倾角之间的对应关系，以利用该对应关系进行转换。具体地，先将第一基站当前的发射功率转换为天线下倾角为0°对应的发射功率，如第一基站当前的发射功率为13dBm、天线下倾角为2°(也可能就是0°，此时无需转换)，转换后的发射功率为15.2dBm、天线下倾角为0°；再将转换后的天线下倾角为0°对应的发射功率作为公式(1)中的第一基站当前的发射功率，采用上述方式得到对应天线下倾角为0°的待调整RF参数的发射功率，如10dBm；最后将采用上述方式得到的待调整RF参数的发射功率对应的天线下倾角转换为第一基站当前的发射功率对应的天线下倾角，转换后的天线下倾角即为待调整RF参数中的天线下倾角，如采用上述方式得到的发射功率为10dBm、天线下倾角为0°。转换后的发射功率为15.2dBm、天线下倾角为5°，则RF参数中的天线下倾角为5°。
在本实施例的另一种实现方式中，该步骤304可以包括：
第一基站选择不同的取值代入公式(1)估计第一基站的RF参数调整为不同取值时各个UE接收第一基站发送的参考信号的RSRP；
第一基站根据第一基站的RF参数调整为不同取值时各个UE接收第一基站发送的参考信号的RSRP计算各个UE接收第一基站发送的参考信号的SINR；
当接收第一基站发送的参考信号的SINR大于或等于信噪比阈值的UE数量小于调整启动阈值时，第一基站将对应的取值作为第一基站的待调整RF参数。
在本实施例的又一种实现方式中，该步骤304可以包括：
第一基站选择不同的取值代入公式(1)估计第一基站的RF参数调整为不同取值时各个UE接收第一基站发送的参考信号的RSRP；
第一基站根据第一基站的RF参数调整为不同取值时各个UE接收第一基站发送的参考信号的RSRP计算各个UE接收接收第一基站发送的参考信号的SINR；
当接收第一基站发送的参考信号的RSRP小于功率阈值且SINR小于信噪比阈值的UE数量小于调整启动阈值时，第一基站将对应的取值作为第一基站 的待调整RF参数。
步骤305：第一基站向子基站发送第一基站的待调整RF参数。
在实际应用中，基站之间的消息交互可以通过X2接口实现。
如前所述，每个基站会将各个相邻基站分别标识为父基站、子基站、祖先基站、子孙基站中的一种，第一基站可依此将第一基站的待调整RF参数发送给相邻基站中标识为子基站的基站。
子基站接收到第一基站(即该基站的父基站)的待调整RF参数后，选择不同的取值代入公式(1)中计算各个UE接收该基站发送的参考信号的RSRP，并采用UE接收该基站发送的参考信号的RSRP、父基站的待调整RF参数计算该基站发送的参考信号的SINR，在接收该基站发送的参考信号的RSRP小于功率阈值且SINR小于信噪比阈值的UE数量小于调整启动阈值时，将对应的取值作为该基站的待调整RF参数，同时也估计出该基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量。即子基站接收至少一个基站的待调整射频RF参数，至少一个基站包括该基站的父基站，根据至少一个基站的RF参数确定该基站的待调整RF参数，并估计该基站的覆盖范围内通信质量小于设定的参数阈值的用户设备UE数量。
该基站根据父基站的待调整RF参数确定自己的待调整RF参数后，将父基站的待调整RF参数、自己的待调整RF参数一起发送给该基站的子基站，即第一基站的子孙基站。
子孙基站接收到第一基站(该基站的祖先基站)的待调整RF参数和子基站(该基站的父基站)的待调整RF参数后，选择不同的取值代入公式(1)中计算各个UE接收该基站发送的参考信号的RSRP，并采用UE接收该基站发送的参考信号的RSRP、祖先基站的待调整RF参数、父基站的待调整RF参数计算该基站发送的参考信号的SINR，在接收该基站发送的参考信号的RSRP小于功率阈值且SINR小于信噪比阈值的UE数量小于调整启动阈值时，将对应的取值作为该基站的待调整RF参数，同时也估计出该基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量。
子孙基站根据祖先基站的待调整RF参数和父基站的待调整RF参数确定自己的待调整RF参数后，将祖先基站的待调整RF参数、父基站的待调整RF参数、以及自己的待调整RF参数一起发送给该基站的子基站。
如此按照树形关系继续，可以在所有子节点都完成上述待调整RF参数的 确定之后结束待调整RF参数的传输，并沿相反路径反馈确定各自的待调整RF参数时估计的各自覆盖范围内通信质量参数小于设定的参数阈值的UE数量。
具体地，子孙基站向子基站(该基站的父基站)反馈确定子孙基站的待调整RF参数时估计的子孙基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量，子基站将接收的子孙基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量和确定子基站的待调整RF参数时估计的子基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量相加，并将相加后的UE数量向父基站反馈，最终第一基站可以收到子基站和子孙基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量之和(即步骤306)。
需要说明的是，如果相邻基站都计算各自覆盖范围重叠区域内通信质量参数小于设定的参数阈值的UE数量，则会造成最后得到的覆盖范围内通信质量参数小于设定的参数阈值的UE数量之和存在重复计算的问题，因此在具体实现中，各个基站会将与子基站和子孙基站的覆盖范围重叠区域内通信质量参数小于设定的参数阈值的UE数量删除，以保证得到的覆盖范围内通信质量参数小于设定的参数阈值的UE数量之和正确。
在实际应用中，也可以由第一基站限定第一基站的待调整RF参数的发送次数实现待调整RF参数的传输结束。优选地，发送次数可以为第一基站的相邻基站的数量，如以图2中的基站b为第一基站，则将发送次数设定为3次。可选地，发送次数还可以根据调整情况进行修改，比如若一次调整后的情况不理想(覆盖范围内通信质量参数小于设定的参数阈值的UE数量减少值小于设定值)，则增大传输次数(将发送次数加上大于0的设定值(如1)、将发送次数乘以大于1的设定值(如1.2)等)；若一次调整后的情况很理想(覆盖范围内通信质量参数小于设定的参数阈值的UE数量减少值大于设定值)，则减小传输次数(将传输次数加上小于0的设定值(如-1)、将传输次数乘以小于1的设定值(如0.8)等)
以图1和图2的场景为例，参见图5，第一基站为基站b，则基站b的待调整RF参数的发送次数为3。基站b向基站a、基站d发送基站b的待调整RF参数，第一次发送第一基站的RF参数；基站a根据基站b的待调整RF参数，确定基站a的待调整RF参数和基站a的覆盖范围内通信质量参数小于设定的参数阈值的UE数量，并向基站b发送基站a的覆盖范围内通信质量参数小于设定的参数阈值的UE数量；基站d根据基站b的待调整RF参数，确定 基站d的待调整RF参数和基站d的覆盖范围内通信质量参数小于设定的参数阈值的UE数量，并向基站c、基站e发送基站b的待调整RF参数、基站d的待调整RF参数，第二次发送第一基站的RF参数；基站c根据基站b的待调整RF参数、基站d的待调整RF参数，确定基站c的待调整RF参数和基站c的覆盖范围内通信质量参数小于设定的参数阈值的UE数量，并向基站d发送基站c的覆盖范围内通信质量参数小于设定的参数阈值的UE数量；基站e根据基站b的待调整RF参数、基站d的待调整RF参数，确定基站e的待调整RF参数和基站e的覆盖范围内通信质量参数小于设定的参数阈值的UE数量，并向基站f发送基站b的待调整RF参数、基站d的待调整RF参数、基站e的待调整RF参数，第三次发送第一基站的RF参数；基站f根据基站b的待调整RF参数、基站d的待调整RF参数、基站e的待调整RF参数，确定基站f的待调整RF参数和基站f的覆盖范围内通信质量参数小于设定的参数阈值的UE数量，并向基站e发送基站f的覆盖范围内通信质量参数小于设定的参数阈值的UE数量；基站e将基站e、基站f的覆盖范围内通信质量参数小于设定的参数阈值的UE数量之和发送给基站d；基站d将基站c、基站d、基站e、基站f的覆盖范围内通信质量参数小于设定的参数阈值的UE数量之和发送给基站b，基站b即可接收到子基站(基站a、基站d)和子孙基站(基站c、基站e、基站f)的覆盖范围内通信质量参数小于设定的参数阈值的UE数量之和。
优选地，该方法还可以包括：
向子孙基站发送待调整RF参数。
子孙基站接收子孙基站的祖先基站的待调整RF参数后，选择不同的取值代入公式(1)中计算各个UE接收该基站发送的参考信号的RSRP，并采用UE接收该基站发送的参考信号的RSRP和祖先基站的待调整RF参数计算该基站发送的参考信号的SINR，在接收该基站发送的参考信号的RSRP小于功率阈值且SINR小于信噪比阈值的UE数量小于调整启动阈值时，将对应的取值作为该基站的待调整RF参数，同时也估计出该基站的覆盖范围内通信质量参数小于设定的参数阈值的UE数量。虽然此时估计的覆盖范围内通信质量参数小于设定的参数阈值的UE数量不能及时反馈给祖先基站，但是却可以更快获取到祖先基站的情况并进行适应性调整，加快调整的速度。
在实际应用中，发送待调整RF参数的消息格式为发送基站标识、接收基站标识、待调整RF参数、消息生成时间。
步骤306：第一基站接收子基站发送的子基站和子孙基站覆盖范围内通信质量参数小于设定的参数阈值的UE数量之和。
在实际应用中，接收覆盖范围内通信质量参数小于设定的参数阈值的UE数量的消息格式为发送基站标识、接收基站标识、UE数量、消息生成时间。
步骤307：第一基站确定第一基站、第一基站的子基站、以及第一基站的子孙基站的覆盖范围内通信质量参数小于参数阈值的UE数量之和是否小于设定的调整结束阈值。当确定第一基站、第一基站的子基站、以及第一基站的子孙基站的覆盖范围内通信质量参数小于参数阈值的UE数量之和小于设定的调整结束阈值时，执行步骤308；当确定第一基站、第一基站的子基站、以及第一基站的子孙基站的覆盖范围内通信质量参数小于参数阈值的UE数量之和大于或等于设定的调整结束阈值时，则执行步骤304。
步骤308：第一基站将RF参数调整为待调整RF参数，并向子基站发送确认信息。
子基站接收到确认信息后，将自己的RF参数调整为自己的待调整RF参数，并向自己的子基站发送确认信息。
子孙基站接收到确认信息后，将自己的RF参数调整为自己的待调整RF参数，并向自己的子基站发送确认信息。
如此按照树形关系继续，使所有参与调整的基站都将自己的RF参数调整为自己的待调整RF参数，实现根据UE的通信质量自动调整基站的RF参数，提高了网络整体的通信质量。
在实际应用中，由于UE移动等原因，会导致UE的通信质量随时间出现变化，当UE通信质量再次变差时，基站由UE的测量报告得知UE的通信质量差而再次发起调整，使基站适应当前UE的分布情况，尽可能保证UE通信质量都好，从而实现根据UE的通信质量进行自适应调整。
本发明实施例通过根据UE反馈的测量报告确定基站的待调整参数，并估计调整后通信质量差的UE，向子基站发送基站的待调整参数，使子基站和子孙基站根据基站的调整参数调整各自的待调整参数，最后当所有基站通信质量差的UE数量小于调整结束阈值时，各个基站将各自的RF参数调整为各自的待调整RF参数，实现根据UE的通信质量自动调整基站的RF参数，提高了网络整体的通信质量，既实现了自动调整，也达到了调整效果，实现简单。
