问题 问答题 简答题

简述诺西eBSC下部分小区吊死/sleepingcell休眠等问题排查的处理建议。

答案

参考答案:

1.发现问题:建议通过打开小区的休眠小区开关来及时发现问题,ENANCD=ENABLED

触发告警的条件是在定义的周期内如果该小区没有一次SDCCH成功占用或小区内某个TRX的CHAN_ACT_ACK和EST_IND的总数相差等于或大于8次,会在周期结束时触发相关的告警,详细描述请参见数据库;建议设置的值为:NCDP1=H8-1,NCDP2=H23-54,8点到23点以每10分钟为一个周期,23点后不触发告警。通过话统文件相关小区计数器确认问题小区;

2).首先通过检查BSC和核心网侧数据确认是否有误;

3).无数据无误,可能是BCCH载频隐形故障问题导致的,建议通过闭锁BCCH载频确认是否问题消除;

4).如第3部操作无法恢复问题小区,则可能是由于BSS侧软件问题导致小区吊死,可以通过如下步骤尝试恢复问题小区:

i.*建议先通过LOCK/UNLOCKBTSM实现基站重新与BSC同步后确认;

ii.*LOCK/UNLOCKPCMB确认;

iii.*切换问题小区相关的LIET接口模块确认;

iv.*中断复原PCMB物理链路确认;

v.*基站小区数据删除创建确认;

5.问题恢复后建议及时与项目沟通收集相关日志问题通过服务热线上报相关故障报告进行具体分析确认问题;
