BSC工作(第三讲CNA的使用)

CNA及CNAI 功能的应用第一部分：CNA操作一、CNA概述Celluar Network Administration(CNA)：在OSS R8.1中CNA提供以下功能：∙提取蜂窝移动网络的信息∙以实际网络配置调整CNA数据库中的CNA信息模型∙以文本或图形方式查看信息模型∙提前规划对网络设置进行大的更改，而不是对实际网络的更改∙通过检查实际网络或规划网络是否一致，来保证网络的一致性。

∙以规划的更改来更新实际的网络∙创建网络设置的备份∙打印信息模型的参数在我的理解上，CNA就好像是电脑操作系统中的DOS和WINDOWS一样，以前我们所采用的DOS操作系统是靠敲打指令对系统进行管理，现在大家都是用图形化界面的WINDOWS了，很操作上很直观，在使用方面使操作简单化，不需要再去记那些DOS指令。

现在的CNA就可以在很多功能上代替了我们在BSC终端上敲打指令的操作（尤其是RLXXX的指令），比如定义小区以及相邻小区，修改小区参数，甚至把小区从一个BSC移动到另外一个BSC，这一点就使得我们在割接变频上变得方便很多，尤其是变频，不再需要像以前那样十几人一起大会战了。

不过在MO部分CNA功能就显得稍弱了些，不得不还是用DT去做。

CNA OverviewValid area: 实模式(real mode) 反应真实网络的配置信息，只可以查看不能更改。

Adjustment用来使Valid area与真实网络的配置信息保持一致，对网络进行更改前后都要执行这一功能，可以在系统设置每隔一段时间Adjust一次。

Planned area: 在规划域用户可以对网络配置进行更改、添加或删除，规划域通过Update将更改、添加或删除在实际网络中实现。

在执行Update之前，Planned area 的任何操作都不会发生在实际网络中。

Fallback area: 是Valid area的完整拷贝，对网络更改前做的备份。

Log area: 通过performance management , traffic recording (PMR)应用建立的，其中保存了bscs , internal cells , 及对应channel groups的重要数据。

二、CNA menu打开CNA在OSS桌面上按右键，如下图选取菜单就可打开CNA的窗口1. Base windows2. FILENew area: 包含下列子菜单Planned area(创建并加载新的规划域)，Fallback area 等。

New job : 包含adjustment job , update job, consistence check job 等菜单Lock/unlock :lock的规划域只有本人才能修改。

这个情况发生在多台终端同时打开一个PLAN AREA时，只有一台终端可以进行修改里面的参数，避免冲突。

3. EDIT这里的操作只能在建立了PLAN AREA后才可以执行，可以执行的操作有：∙Create objects in Planned Areas∙Copy parameter values and paste them into objects∙Delete objects in Planned Areas∙Restore objects∙Move Internal Cells from one BSC to another BSC∙Connect Channel Groups to the selected Transceiver Group∙Disconnect Channel Groups from the selected Transceiver Group 4. View查看左边选中对象的属性及与其它对象之间的关系。

5. Optionconnect to GCC: 建立cna与GCC之间的双向通讯consistency check preferences : 一致性检查的参数设置CNA preferences : CNA配置参数设置6. Network Elements显示所选对象的属性(data and parameters)，包括Area , Msc , Bsc , Site , Transceiver Group , Internal Cell , Inner Cell , External Cell , Outer Cell , Overlaid Subcell , Channel Group , Neighbour Relation , Foreign Cell .三、CNA Preferences1. MiscellaneousOutput to：输出到打印机或是文件中Base Window：设置CNA base window 的显示信息Graphical Cell Configuration：当CNA 启动时，是否自动连接GCC2. PlanningAuto creation：创建Internal Cell 时，是否自动建立Inner CellArea creation：创建规划域后是否自动载入base window 并锁定Auto deletion：Inner cells --- 删除internal cell 时，是否自动删除对应的inner cells External cells --- 删除internal cell 或对应的相邻关系时，是否自动删除对应的External cellsOuter cells --- 删除internal cell 或对应的相邻关系时，是否自动删除对应的Outer cellsAuto Parameter Synchronization：Active/Idle list是否与相邻小区的DCCHNO参数自动同步；3. Job default valuesAdjustment jobs：extent -- 是否adjust 所有参数，包括AXE文件大小和小区状态。

Check only (no)—cna检查网络和valid area 之间的不同，并对valid area 进行adjust 。

Action on fault –从网元返回来错误代码时，是否停止下一个MML的执行。

Fallback Area –开始adjust 时，是否创建fallback area 。

Consistency check jobs点击其中的File…按钮，选择以前保存的一致性检查规则，避免每次进行一致性检查都要重新设定检查规则。

4. System administration四、Consistency check Preferences一致性检查，检查规划域参数的一致性。

如果违反了相关参数的设定规则、门限值、相互关系，则产生告警，以阻止用户在规划域输入不一致的参数并将其应用于实际网络。

用户也可以选择忽略(ignore)告警，把不一致的参数输入实际网络。

强烈建议在用规划域plan area做update之前，做一个完整的一致性检查。
