S401：通过网络监听获取邻区RSRP、通过X2口获取邻区负荷信息用户数。
S402：判断最强邻区用户数加上当前服务小区的用户数之和是否高于用户数门限，如果是，转到步骤405，否则，转到步骤403。最强邻区指的是在服务小区的所有邻区中其RSRP最高。用户数门限是算法配置值，比如96个用户。
S403：判断最强邻区RSRP是否高于RSRP门限A，如果是，转到S407，否则，转到S404。RSRP门限A是算法配置值，比如-60dBm，最强邻区的RSRP高于RSRP门限1表明存在较强的干扰邻区。
S404：判断最强邻区RSRP是否低于RSRP门限B，如果是，转到S405，否则，转到S406。RSRP门限B是算法配置值，比如-100dBm，最强邻区RSRP低于RSRP门限B表明邻区干扰不严重。
S405：增加小区发射功率,小区发射功率上调一个上调步长，上调步长是算法配置值，比如1dB。
S406：小区功率发射保持不变。
S407：减小小区发射功率，小区发射功率下调一个下调步长，下调步长是算法配置值，比如2dB。
S408：调整当前服务小区的相关参数配置包含小区使用功率、小区使用的导频配置、RRC相关的参数配置，例如导频功率可以通过小区功率计算得到。
