3.4G Basic switch and threshold audit
3.1 4G basic switch and threshold audit
3.1.1 Rules
Check the values base on the BASIC LINE. You need to maintain the basic line, once the switch or threshold
changed we must updated the BASIC LINE.
Customer requirement:
LTE BASCI LINE-OMSTATR:
LTE Baseline
-OMstar.xlsx
3.1.2 Tool
OMSTAR
3.1.3 Process

Import the basic line (LTE BASCI LINE-OMSTATR) into OMSTAR
 Choose Parameter > LTE Config Parameters Check on the OMSTAR menu bar to enable the LTE
configure Parameters check function.
 In the LTE Config Parameters Check setting dialog box, set parameters as required, as shown in
following:

 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:

 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.

4.1.1 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.
