 Original data path: Select the eNodeB configuration data to be checked. You can choose one or more eNodeB configuration files to check. To select multiple eNodeB files, put the files in a folder, and select the folder to perform the check. It is suggested to check the eNodeBs with same version during one process.  Save Path: Specify a path where you want to save the check result.  Language Setting: Set the interface and report language, either Chinese or English.  Select Mode: Select a product mode. Mode FDD and TDD correspond to different configuration parameter baseline templates.  Scene: Select a check scenario based on the actual service networking, we can choose the default for check all the parameters of the whole network. You can choose OPERATOR BASIC line for check the customer’s requirement.  Filter: In the selected scenario, filter parameters according to parameter types. The selected parameters will be checked, and other parameters will not be checked. OMStar V500R010 provides two parameter filtering indicators, Parameter_Type, and Subject. OMStar V500R010 check all parameters by default without filtering..  Combine by MO: In the check report exported, combine the check results of the configuration parameters that are of the same object level. Table 2 lists the managed objects (MOs) that can be combined. For details, see the .xml configuration file OMStarV500R010\client\conf\parameter\lteparameter.xml. Do not modify the file.  Output details: Output all check results, including the items that pass or fail the check. If this function is not enabled, only the failed items (the parameters that are not consistent with those defined in the baseline templates) are shown in the check report, but the items that pass the check (the parameters that are consistent with those defined in the baseline templates) will not be displayed. However, if this function is enabled, all check results are exported.

Result:  The detailed check results are recorded in the PassNum and ParaIDNotFound columns. The PassNum column records the parameters that are configured as the values defined in the baseline templates. The ParaIDNotFound column records the parameters that are not configured as the values defined in the baseline templates, as shown as following: Figure 1 Instruction sheet

 On the MoNotFound sheet, the MOs that exist in the baseline template but are not configured are displayed. (If you check the configuration of multiple eNodeBs at one time and an MO does not exist in one of the eNodeBs, the MO is regarded as the one that exist in the baseline template but are not configured, and is recorded on the MoNotFound sheet.)  Each MO sheet records the detailed MO check results of all eNodeBs. The cells rendered in red are the parameters that are not configured as the values defined in the baseline templates. The cells rendered in yellow are the parameters that exist in the baseline templates but are not configured. The cells that are not rendered but filled in with values are the parameters that are configured as the values defined in the baseline templates. Use LCELL as an example, as shown in Figure 5.

4.4G External cell and neighbors audit 4.1 4G external cell and neighbors audit 4.1.1 Rules  

External cell: Check whether the parameter configuration for external LTE cells is consistent with that for the source cell within the system, redundant external cell. Neighbors: Check and restore unidirectional neighbors, more (50) or less (5) neighbors, overshot neighbors (5km), Co-site missing neighbors. 4.1.2 Tool CME, OMSTAR 4.1.3 Process -- CME

On the menu bar of the planned data area, choose Advanced >Consistency

Check. Then the process is same the ECGI audit (2.5) until “the Select Rules”. Select the following options. Then next. The others are same with the ECGI audit.

4.1.4 Process – OMSTAR  Select Analysis Task Management > Theme Function > LTE Subject > LTE Neighboring Cell Check.  Double click LTE Neighboring Cell Check. The New Rask window is displayed. Enter a task name. Click Next.  Select NEs about which data is to be analyzed on the NE Selecting tab page and set parameters for neighboring cell check on the Parameters Setting tab page. Click OK.  Then the task is created and displayed in the task pane. After being created, the task starts to be executed by default. After the task execution is complete, the Status field in the task pane changes to Finish.  Double-click a row following the Status field value in the task pane. The neighboring cell check result window is displayed. In the Neighbor LTE Cell Check Summarized Results area, the One-way Neighbors, Over Distance Neighbors, Too Many Too Few Neighbor Cells, External Neighbor Cell Parameter Inconsistency, Co-site Missing Neighbors, LTE Redundancy External Cell, GSM Redundancy External Cell and UMTS Redundancy External Cell and so on pages are displayed.
