数据可能丢失!保证VDS的连接指向,保存计费数据,先进行主备切换后再对备用单元进行重启动作.要频繁切换,且注意切换顺序.(SP-WO)
总线连接及状态.
时隙路由配置
间的电缆连接
故障期间的文件拷入该硬盘,以保证数据文件的正确传送.
复之前不要重启主用单元,以避免数据重写.
致性.
重新用ZII?命令将报告连至disk文件(逻辑文件为FRAUDREP),用MXR(MSC中)和MJR (HLR中)增加TCP/IP地址和端口
能是硬件存在故障,用ISI及ISC命令检查并将DISK状态改为WO-BU(注意解决硬件故障后需要update内存中的SOMAFI文件到DISK) 4.确认硬盘故障则按正障引起,应按正确的操作方法进行更换.
4.从另一正常的DISK上拷贝整个目录(IPS)
5.将硬盘状态改回WO-BU
6.允许文件更新(DUR,DBR)
确认硬盘故障则按正确的操作步骤进行更换.。

LTE网络问题定位分析及解决案例优化案例：PCI模3冲突/SINR差☐问题描述：问题路段（桥面）信号杂乱，各路信号强度相近无主控小区，路测结果显示该路段RSRP尚可、SINR值较差☐问题分析：UE占用金祥大厦PCI_178小区的信号，与最强邻区湖中烟厂PCI_490产生MOD 3干扰，导致该路段切换前后SINR极低☐调整方案：☐优化结果：SINR有明显改善。

SINR差SINR好小区PCI调整前调整后金祥大厦-1 178178179金祥大厦-2 179179178优化案例：无主覆盖/SINR差☐问题描述：覆盖不稳且信号杂乱，在多个小区间频繁切换。

导致该路段SINR较差☐问题分析：问题路段距离周边基站均比较近，其中主要收到的有火车站EGSM、金榜南门、东南亚酒店等多重RSRP较为接近的信号（凯旋广场未开启）；无主覆盖、信号不稳、切换频繁，还有模3干扰☐调整方案：通过上站发现，距离最近的火车站EGSM站点扇区并未沿着道路覆盖，将火车站EGSM 二扇区方位角为50°调为80°，下倾角由10°调为1°，三扇区方位角由250°调整为210°，下倾角由8°调整为2°；火车站EGSM的PCI_351与PCI_353对调☐优化结果：SINR有明显改善。

SINR差SINR好优化案例：低电平/低质量☐问题描述：在两个基站中间部分的RSRP低到-110dbm以下造成SINR很差☐问题分析：两个基站(云顶至尊监控杆和华林花园监控杆之间相距1000米)，两个小区的有效覆盖在300米左右，在中间部分由于弱覆盖导致其SINR值较低☐调整方案：该路段已无法通过新增基站和调整天线的方式改善覆盖。

功率也已经设置为10W，修改dlRsBoost（Downlink reference signals transmission power boost）☐优化结果：SINR有明显改善。

诺基亚LTEKPI及性能相关告警KPI及性能相关告警KPI的定义：KPI的counter:考虑与KPI及性能相关的告警，如果只关注平时正常运维的情况，不外乎两类：1.硬件类告警，导致基站或⼩区退服2.传输类告警，导致S1或X2连接中断下⾯讨论⼀些⽐较常见的告警类型。

1.RP3告警对于eNB⽽⾔，只要cell不是OnAir的状态，那么该⼩区均⽆法处理呼叫，⽽所有导致⼩区退服的告警都属于这⼀类，由于基站或⼩区退服了，所以该类告警会影响所有KPI及性能指标,区别只在市整个基站的指标还是某⼩区的指标。

⼀般⽽⾔，该类告警有两种7650BASESTATIONFAULTY和7653CELLFAULTY这两类告警通常是硬件告警，如BBU,RRU,Antenna,以及他们之间的链路出现硬件故障，最典型的当数RP3告警，FailureinopticalRP3interface，相⽐较RP3告警，模块的硬件故障从⽐例上来说要相对少很多所谓RP3即BBU与RRU的接⼝。

这种告警也是最常见的告警，告警内容多为光路告警。

⽬前这类告警常见的fault有0010、4064和2004。

其中0010和4064严重时会导致⼩区退服、基站退服。

但是2004⼀般只是⼩区性能下降，不会引起⼩区退服。

1.1Fault0010：Noconnectiontounit1、可以先尝试重启基站观察2、检查光⼝速率是否匹配（强制8x速率）BBU侧强制8x速率设置：先检查SWCONFIG中0X19000C字段，对于软件版本RL25，0x19000C=1,及代表8x光速率，0代表4x光速率；对于软件版本RL35，0x19000C=0，代表⾃适应，1代表4x，2代表8x，注意不同软件版本的区别。

RRU侧强制8x速率设置：telnet到RRU上，端⼝号是2323，使⽤命令rad–r0查看RRU的所有参数配置。

找到0xED这个参数，看⼀下它当前的值是0还是1。

0表⽰⾃适应，1表⽰强制8x。

上述原因直接促使了负载均衡技术的诞生，在保证用户的服务质量的同时，使网络总容量达到最大化。

目前所支持的负载均衡功能如下：iFLB：Inter Frequency Load Balance 异频负载平衡当高负荷小区的负荷超过High Load门限后进入iFLB激活状态，并可以触发LB切换，直到小区负荷低于Target load门限，则退出iFLB激活状态；在iFLB激活状态期间，ENB间的负荷信息不通过X2接口进行交互，所以这种状态下触发的LB切换属于邻区负荷未知的盲切换，只要目标邻区的下行rsrp大于设定的LNHOIF:thresholdRsrpIFLBFilter参数门限就会触发。

而当切换请求消息(Handover Request Cause: Reduce Load in Serving Cell)发送给异频的目标邻区时如果邻区负荷已经超过了自己小区设置的Target Load门限的话，邻区会拒绝该切换请求。

上行预调度功能实验报告-诺基亚1. 概述Nokia_LTE预调度只有一个参数ilReacTimerUl，该参数的基本含义是“当上行传输的数据块传完之后，在上行给UE保留资源上的时长”。

1500就是说保留1500ms，200就是说保留200ms。

保留的资源并不是等同于上次调度了多少PRB就保留多少PRB，直到这个Timer超时。

预留的时长越长，意味着在UE有调度需求时，有更大的概率能够得到最快的响应，但相应的系统的额外开销也会增大，传送相同的数据量所需的资源会增加，PRB利用率会随着升高。

预调度存在的意义是减少LTE系统时延，一些小包业务，由于上行需要给下行的数据回复ACK/NACK,没有预调度时，就需要上行先SR，然后在上行资源上回复，有了预调度就可以及时反馈。

当打开预调度开关时，由于eNodeB周期性给UE发送UL Grant来分配资源，当UE没有或者是有少量的上行数据需要发送时，会以Padding填充发送，填充消耗的RB比真正用于数据传送的RB还要多，因此，打开预调度开关会引起额外的RB资源消耗。

2. 实验情况：2.1场景一普通大业务场景-上下行都忙选定场景1测试：当上行预调度功能开启前后，主要对LTE系统时延、上行PRB利用率及其他影响。

1）站点选取：通过筛选22日早8：00-23:00全网KPI，选定普通大业务场景-上下行都忙小区为朝阳南湖西园119号楼NL12）外场反馈测试结果：外场反馈测试结果见下表，由下表值测试结果符合预期，关闭上行预调度功能（关闭时间：3） KPI部分：由下表知，关闭上行预调度功能，上行PRB利用率下降16.8%2.2场景二普通大业务场景-上行忙下行闲1）站点选取：通过筛选22日早8：00-23:00全网KPI，选定普通大业务场景-上行忙下行闲小区为朝阳望京华联2NLM12）外场反馈测试结果：外场反馈测试结果见下表。

由下表可知，当上行预调度功能关闭时（ilReacTimerUl=0ms）,时延最长（91ms），当上行预调度参数3） KPI部分：测试对应时间点：第一组10:45-11:00（ilReacTimerUl=200ms）, 第二组11:00-11:15（ilReacTimerUl=5ms）, 第三组11:15-11:30（ilReacTimerUl=100ms）, 第四组11:30-11:45（ilReacTimerUl=1500ms）, 第五组10:45-11:00（ilReacTimerUl=0ms）。

小区帧偏干扰优化分析处理一、问题分析背景干扰是影响网络质量的关键因素之一，对通话质量、掉话、切换、吞吐量均有显著影响，2017年1月25日红角洲南大医学院周边存在强干扰，导致周边移动4G用户无法接入，上网感知差，为此南昌专项针对此区域内的干扰进行了详细西施的排查。

二、干扰排查流程LTE系统最常遇到的干扰可以分为系统内干扰、系统外干扰几类，系统内干扰主要是同频干扰，包括如LTE TDD帧失步（GPS失锁）、TDD超远干扰、数据配置错误导致干扰、越区覆盖导致干扰等；系统外干扰主要是异系统非法使用LTE频段、异系统的杂散、阻塞或者互调干扰对本系统的影响。

以下为干扰排查流程图：三、南大医学院干扰排查分析3.1 问题现象2017年1月25日红角洲南大医学院周边华为站点及工贸学院区域诺基亚站点RRC成功率及接通率指标明显异常，通过提取TOP小区的干扰情况，发现KPI指标差的小区均存在不同程度的干扰，受干扰的区域如下图：受干扰区域4G小区的KPI指标如下：3.2干扰排查定位通过提取区域内华为和诺基亚站点的干扰指标情况进行定位分析，发现干扰强度以红角洲南大医学院第五实验大楼(D)1为中心扩散开，干扰水平如下：从上表可以看出，受干扰的均为D频段小区，且干扰最强的小区为红角洲南大医学院第五实验大楼(D)的3个小区，而周边F频段小区并无干扰，F频段小区干扰水平截图如下：从这一现象来看，疑似为D频段小区GPS跑偏导致周边站点干扰，为进一步排查问题，后台逐一将干扰强的小区进行闭锁验证，在闭锁红角洲南大医学院第五实验大楼(D)的3个小区闭锁后，从实时干扰监控来看，周边站点的干扰恢复至正常水平，截图如下：综上分析，干扰源4G站点已确定为红角洲南大医学院第五实验大楼(D)，查询该站点告警信息，该站并未有GPS跑偏告警及其他任何告警，截图如下：3.3 干扰协同优化处理为解决红角洲南大医学院第五实验大楼(D)对周边站点造成的干扰的具体原因，在诺基亚工程支撑分析下定位原因为：此站点采用FZFH开通双通道D频段，该站点帧偏为0，确认帧偏置异常，非规范。
