说明掉话跟压模有关，需要优化连续覆盖区域小区的压模参数，降低小区异频/异系统起压模门限，减少起压模次

数

a) 通过M2000查看这两个小区所在NodeB是否有异常告警（例如时钟、通道、DSP和射频告警），如果有需要先处理异常告警。

b) （可选）对两个小区所在站点进行时钟核查。c) （可选）利用RNC维护台小区性能监测中的节点同步功能（如下图）检查这两个小区的Iub时延，如果时延相差超过SET DPUCFGDATA中 FPMDCCOMBINEDELAYVALUE设置值（基线为20ms）,修改上行FP合并时延等于两小区Iub时延差+20ms。

d) 如果这两个小区没有异常告警，Iub时延也正常，可以尝试修改源小区相对目标小区的CIO（ADD/MOD INTRAFREQNCELL: CIOOffset=10）,如果修改后有效，说明切换失败是信号突变引起的；反之，需要把CIO改回0。

ii. 查询接入失败的小区是否是RNC边界的小区，如果是可以修改该小区同频重选门限

iii. 失败原因是否有资源拥塞，如果资源资源拥塞，可以参照TOP小区资源拥塞核查子动作进行相关检查

关闭直放站后在观察一下小区RRC接入指标，如果有改善，说明接入失败与直放站确有关系，需要关闭直放站如果直放站关闭前后，小区RRC接入指标变化较小，说明RRC接入失败与直放站没有关系
