NSN TDS_NodeB维护排障实用手册
常见故障处理建议目前NodeB le主要故障主要分为传输故障、硬件故障及GPS系统故障3类传输故障SCTP链路故障告警告警解释：当基站检测到SCTP（Stream Control Transmission Protocol，流控制传输协议）链路无法承载业务时，产生此告警可能原因：·SCTP的承载链路故障·和对端设备配置参数不一致·到对端的路由不可达·光纤连接错误·对端设备故障处理步骤：1 远程检查承载链路相关告警a在网管中心的告警台上，检查承载该SCTPLNK的链路（ETH/PPP/MLPPP）是否存在以太网相关告警或者PPP/MLPPP相关告警：b 按照相关告警的处理建议排除故障。
2 远程检查SCTP链路两端配置参数a 执行MML命令LST SCTPLNK查看本端SCTP链路的所有配置参数与配置规划是否一致，如本端IP地址、本端SCTP端口号、对端IP地址、对端SCTP端口号等b 执行MML命令RMV SCTPLNK, ADD SCTPLNK修改错误的配置参数3 远程检查路由a 执行MML命令DSP IPRT检查承载该故障SCTP的链路上是否配置了到对端的IP路由b 执行MML命令ADD IPRT增加承载对应链路上到对端的IP路由4 检查承载网络配置是否正常a 和承载网络的网络管理人员联系，确认承载网络中设备的路由等配置是否正确，并且没有屏蔽Ping报文b 请联系网络管理人员修正网络配置5 检查网线连接是否正确a 和承载网络的网络管理人员联系，确认承载网络中设备的网线连接是否和配置一致b 请联系网络管理人员修正网线连接6 检查对端设备是否正常a 检查对端设备是否正常b 处理对端设备故障远程维护通道故障告警告警解释当远程维护通道异常导致基站无法维护时，产生此告警。
可能原因·远程维护通道未配置或配置错误（主要体现于逻辑网元布配与实际物理布配不一致）。

合路器介绍--AFE 合路器介绍--AFE -四块载频时AFE的信号流向问题 单极化天线） （单极化天线） 因为是收发双工，所以主发射天 线即承担了发射功能又承担了主 接收功能，而分集接收天线仅仅 实现分集接收功能，以达到分集 增益的功效。

合路器介绍--AFE 合路器介绍--AFE -使用AFE合路器的四载频扇区（单极化天线），如果出现问题将会怎么样？ （单极化天线），如果出现问题将会怎么样？ ），如果出现问题将会怎么样 1、从前面的图片可以看出， AFE合路器的四载频扇区（单极化天线）进行信号的 （单极化天线） 发射，所以其中一根天馈出现问题时，将会引起所带的两块载频同时出现问题。 例如：一根天线驻波比过高时，连接它的两块载频可能同时出现退服现象。 2、由于两根天线同时发射信号，所以对天线的方向、下倾角一致性要求更高。假 如天线不一致会出现什么情况呢？肯定造成覆盖区域不完全相同，可能会引起掉 话等情况，下面将进行分析。

nsn干扰排查工作手册
前言随着4G LTE基站的逐步建设，涉及电信/联通TDD/FDD站点的建设，目前已形成了2/3/4G基站共存的局面，系统间干扰的概率也大幅提高，在目前已建设的移动LTE基站中，已发现大量的TD-LTE基站受到上行干扰。
这些干扰重要涉及2/3G社区对TD-LTE社区的阻塞、互调和杂散干扰，此外尚有其他无线电设备，如PHS基站带来的外部同频干扰，具体如下表：1.干扰产生的因素和分类：1.1按照干扰产生的起因可以将干扰分为系统内干扰和系统间干扰。
系统内干扰的产生：系统内干扰通常为同频干扰。
由于数字技术相对于模拟技术的抗干扰能力较强，可以实现同频组网。
比如，TD-SCDMA 系统中，同一个社区内的不同用户使用的是相同的频率资源，它们之间是通过正交码字来进行区分的。
TD-LTE 系统中，虽然同一个社区内的不同用户不能使用相同频率资源（多用户MIMO 除外），但相邻社区可以使用相同的频率资源。
这些在同一系统内使用相同频率资源的设备间将会产生干扰，也称为系统内干扰。
系统间干扰的产生：系统间干扰通常为异频干扰。
世上没有完美的无线电发射机和接受机。
科学理论表白抱负滤波器是不可实现的，也就是说无法将信号严格束缚在指定的工作频率内。
因此，发射机在指定信道发射的同时将泄漏部分功率到其他频率，接受机在指定信道接受时也会收到其他频率上的功率，也就产生了系统间干扰。
1.2干扰产生的因素：一般来说干扰重要受使用频率、设备能力及工程实行三个因素制约。
1.2.1使用频率因素：干扰大小与干扰源系统和受害系统使用的频率有关。
●当干扰源系统的发射频率与受害系统的接受频率距离较近时，也许产生带外杂散和阻塞干扰；●当干扰源系统的发射频率（f1）与受害系统的接受频率（f2）是有倍数关系时，也许产生谐波干扰，如f2=2*f1 将也许产生二次谐波干扰；●当干扰源系统在多个频率上发射（如f1 和f2），且其多个发射频率的线性组合（如f1+f2、f1-f2、2*f1-f2、2*f2-f1 等）正好落入受害系统的接受频率范围之内，也许产生互调干扰。

NSN常用参数解释、常用操作及常见告警
常用参数简称名字1 HYS 小区重选滞后作用：当2个基站在LAC交界处时，位置更新频繁，造成SDCCH拥塞，提高本基站的HYS的dB值，可使小区重选难度提高，次数减少；只对不同LAC间的小区有作用。
邻区（位置区与本区不同）信号电平必须比本区信号电平大，且其差值必须大于小区重选滞后规定的值，移动台才启动小区重选。
2 RXP（rxlev access min）本基站的最小接收电平值作用：手机在接入网络时需要的最小电平值，可以起到分担基站话务的作用3 RE（call reestablishment allowed）通话重建作用：基站在通话过程中，在信号断续情况下，允许通话重新建立4 RLT（radio link timeout) 无线连接超时作用：在通话过程中，定义的最大的无线连接时间。
5 AG（number of blocks for access grant msg）接入准许保留块数作用：在CCCH中保留允许呼叫建立的个数6 MFR(Number of Multiframes) 寻呼信道复帧数作用：确定了将一个小区中的寻呼信道分配成多少寻呼子信道7 PER（TimerforPeriodicMSLocationUpdating）周期位置更新定时器作用：确定手机当时所在的LAC区域8 DTX 不连续发射作用：控制移动站在通话过程中是否采用DTX9 HOP（BTS hopping mode）BTS跳频方式作用：减少干扰，但受到硬件质量的影响很大。
10 DR（Directed Retry Used）直接重试作用：呼叫过程中，BSS直接将MS指配到邻区的TCH信道上DRM （Directed Retry Method）DR的方式作用：在需要调整DRT参数是用，设置为1DRT （Directed Retry Threshold）DR的门限值作用：当相邻小区的信号电平低于此门限值，不允许作为DR的选择11 PMRG（HOMarginPBGR）功率预算的切换边界作用：为了防止来回切换，源小区此值增大，可使较难切出，尽可能的保留话务在原小区；或源小区减小，容易切出到目标小区12 C2（cell reselect）小区重选作用：在微蜂窝和DCS情况下，可以激活C2的算法REO（cell reselect offset）小区重选偏置作用：提高REO值，使手机小区重选时尽可能保留原小区（如DCS1800站）13 RDIV(RX diversity) 分集接收作用：选择W定义在BTS中打开分集接收功能，但只在Ultrasite打开W14 CBA（Cell Bar Access）小区接入禁止作用：当微蜂窝载频数很少，容易引起拥塞，可考虑CBA设置为1，不能起呼，但容易切换进来15 LMRG 信号电平的切换门限16 LUR（threshold level uplink Rx level）上行接收电平门限（切换算法）作用：当基站接收的上行电平低于一定门限时，网络应启动切换算法，以使移动台能维持一定的通信质量LUR（pc lower threshold lev ul）上行接收电平功率控制下限作用：当基站接收的上行电平低于该门限值时，基站将启动功率控制过程，提高移动台的发信功率。

2.虽然3G技术已经针对2G系统的不足，在加强分组数据传输性能方面做了很大的增强，但市场需求的快速增长将使得3G R4定义的2Mbps峰值传输速率显得不足。
对此，在第三代移动通信技术的发展过程中，3GPP在R5和R6版本规范中分别引入了重要的增强技术，即__HSDPA_____和___HSUPA____技术。
R5版本主要定义了___ 全IP______的架构，R6版本的重点则集中于业务增强及与其他网络的互通方面。
3.覆盖调整是TD-SCDMA优化的第一步，覆盖优化的目标是95%的覆盖面积内PCCPCH的RSCP达到______-95____ 以上，PCCPCH的C/I达到______-3_____ 以上不小于95%。
4.T D-SCDMA系统无线帧结构中，有个特殊时隙GP（保护间隔）由96个码片组成，时长75μs，由此可以确定基本的小区覆盖半径为___11.25___km。

工作意向
【关于通信设备厂商公司的2010年就业考虑】- 阿朗，华为，中兴，大唐，爱立信，诺西，鼎桥，普天，思科，MOTO等作为过来人，我认为：如果是一个档次的公司就不要违约了，比如：华为，中兴等。
关于以上公司的就业问题，我来总结和归纳一下，大家可以讨论，对于2010应届生，最终的OFFER选择还得大家本人拿主意！呵呵！现主要讨论以上公司的研发岗位OFFER的比较：【HW】工作主要看：公司+岗位+薪水，若都是做研发，华为就不用说了，华为就是累些，公司+岗位+薪水各方面都不错，工作3年后钱更多，但很少人会在那里工作很久，一般都是积累跳槽的资本。
华为在上海，南京，深圳，北京，西安等都有分支，工资是6500/月+年终奖（前几年会很少，一般是1~2个月工资左右），工作多年后会有分红较多。
应该说在HW工作10年的收入是其他公司的好几倍不止。
同时，HW挖人相当厉害，在其他公司工作多年后跳槽来HW，HW会开出很高的年薪。
比如硕士+3年工作经验=15岗左右。
其实进华为的最好方法是在其他大型公司工作几年，而且表现很好，技术好的人再来HW较好，都是在外工作多年的硕士一般年龄也较大，很少能来华为吃苦了。
自己的一个师兄，上海，硕士毕业工作3年后，HW开出的薪水是16K*18的年薪来挖他，但是师兄30多了，怕累，也受不了华为的文化制度，就拒了，去了一家小外资做研发，轻松，28W一年。
大家看到，很多从华为出来的普通技术人员都跳槽进小公司做骨干。
当然大家都会有自己的考虑。
【ZTE】中兴也不错，中兴只是钱较其他公司少些，但做核心技术研发应该比阿朗上海贝尔好些，中兴不是一个很有争议的公司，薪水5750+补助（几百元）+年终奖（1个月，前几年），工作较轻松，自己毕业的师兄一个进HW，一个进ZTE，进ZTE的师兄说工资难涨，但没有加班，他是做固件工程师研发，上海。
里面呆着还行。
他的2年后计划也是跳槽，当然可能比较中意跳去外资，可以开高价，也不累。
