This guide is drafted for radio network planning and optimization engineers.

1.3 GSM system IntroductionThe GSM system structure is showing as following, the radio planning and optimization mostly focus on the BSS part.

Figure 1 GSM system structure

In different GSM network, different OM client, the IP addresses mostly are different, the user name and password are also different. They are managed and distributed by OMC administrator. Every OMCR should follow the rules of the OMC.For example, there are 2 BSCs in one network, the IP addresses, user names and passwords like the following table:

Table 1: equipment IP address and maintenance account example

1.4 OMCR Services RegulationsRF engineers work in the OMCR should follow the OMCR regulations, and pay attention to below points:

1) Ask for customers permission before entering the equipment room. Register the carry-on articles while going in or out of the equipment room.

2) Strictly abide by customers rules and regulations. For example, make sure whether the customer requires you to put on a shoe cover before entering the equipment room.

3) Smoking, game playing and operating the equipment provided by other vendors without permission in the equipment room are strictly forbidden.

4) Its forbidden to access to the internet websites which are not related to the on-site service.

5) Equipment operation and maintenance are not allowed without customer permission and accompanying; in principles, temporary account and password provided by customers should be used for this purpose. The use of super-password before customers is forbidden. In principle, the operation should be within the scope of operation approved by customers. Exceptional operations should be applied to customers and explanations on possible impacts should be provided.

6) If the equipment runs normally, do not perform any dangerous operations during peak hours and periods for the appraisal of communication indexes or periods of communication assurance.

7) Clean up the site after the service is completed to keep the equipment room tidy and clean;

2 BSC6900 LMT OperationsThe LMT provides graphical user interface (GUI) for you to operate and maintain the BSC6900 on the web page. You can perform the alarm management, trace management, performance monitoring, and device maintenance through menu operations. You can also run the MML commands and read the corresponding execution results on the LMT.2.1 MML Commands2.1.1 Introduction to MML commandsAn MML command consists of two parts: action and object, for example, ADD OP, wherein ADD is the action and OP is the object. Given below list describes the actions that can be performed through MML commands. Some useful action for the reference:

ActionDescription

ACTActivate

ADDAdd

CHKCheck

Table 2: description of some useful commands2.1.2 Make MML CommandsSelect one NE from iManager M2000 of same version for which MML commands need to be executed. After that web browser open and you chose MML section to create the script snapshot will help you how to do work and make the script.

Step 1:

Login Main Topology of iManager M2000, select on NE in which you want to run the script

Step 2:Choose MML from the tab; input the command in Command Input box, and then Exec.

2.1.3 Run Script in BatchCopy the script and paste your script in the BATCH tab then press the button of GO to execute the script the script will run and successfully complete. If any problem occurs then script will stop and tell you where and which line of script have error then you go to execution type box and chose the option of Run from line and enter the line number from where error occurs. If you successfully run the script and parameter change off all the cells of NE.

2.2 Alarms

This describes how to manage BSC6900 alarms through the LMT. Through the alarm management, you can analyze the alarms more efficiently to facilitate the troubleshooting.

If you want to take all alarms of the NE, you simply press the refresh button then press the save all records button to save the alarms records in your PC.

If you want to query the alarm logs, you can choose the Query Alarm Log tab. First choose the alarm time you want, you can select the alarm type and alarm severity as well, then you chose the site and press the button of Query the result will be shown on your system after that you save the record.

2.3 Device MaintenanceIn this tab we can check the live status of the site from Monitor channel status. We can check the monitor channel interference band and also modify administrative status in which we can lock the Cell, TRX, and Channel.

2.3.1 Monitor Channel status

2.3.2 Lock/ Unlock TRX

2.3.3 Monitor Interference Band

In Monitor Interference band we can check the interference on the channel there are 5 type of interference band.

2.4 Trace

Trace management is performed in the routine maintenance of equipment. You can trace the messages on the interfaces and signaling links to verify data and locate faults. Do not start excessive tracing tasks when the traffic load is high. Otherwise, the LMT response speed is very slow. In this case, set Trace Mode to Save To OMU when you start a tracing task.

4 CME OperationsCME (Configuration Management Express) is a Huawei Tool used for the configuration. It can be used for the configuration of cell sites. CME works in Parallel with iManager M2000. It means we cannot use CME until we login to M2000 server. In CME, we can create BTS, configure or modify Cell parameters, frequencies etc. Basically what CME does is it creates MML scripts for every action that we perform on the Cell/TRX. In the end, we can use these MML commands to actually apply those actions/changes.This chapter is made with respect of RF End. It does not cover the topics which are related to the BSS end.

4.1 Introduction to CME4.1.1 How to login to CME

To login to CME, open iManager M2000, go to Maintenance Tab(CME;

4.1.2 Plan Area and Current Area1. Current Area: we can only view the NEs and its parameters, any type of modification is not allowed. So if we want to see some parameter vales, it is better to use the current area, use of planned area is not recommended in order to avoid unwanted changes in the database.To open the current area, go to Area Management(Open Current

2. Planned Area: If we want change the values of any parameter; we can use the planned area.

(1) See the below images to know how a planned area is created.

(2) Give a name to your planned area, and select the NEs that you want to include in the planned area.

(3) Click the OK button, and it will start processing.

(4) We can swap between the current and planned are according to our requirement. Below image shows how to swap between the current and planned are.

3. Area Synchronization: CME does not support automatic synchronization of Database, we have to synchronize manually. Synchronizing all the NEs at a time is NOT RECOMMENDED because it can cause the OML Link to get congested.

4.2 Parameter change

We will show the steps to make the cell level parameter change as an example.

14. Right click the cell you want to perform the parameter change in plan area, and select Cell Configuration Express.

15. In cell Configuration express window, we can see all the cell level parameters e.g. Idle Mode Parameters, Call Control Parameters, Handover Parameters etc. See Below;

1. Shows Cell Name

2. Details of the Cell (Cell Index, Cell ID etc)

3. Parameter Categories

4. Parameter list of the concerned Category

1. Go to the desired parameter you want to change. For example, if we want to change the parameter Concentric Circle HO Allowed, go to Handover Parameters, click on HO Basic Parameters. A list of related parameters is displayed on the right side of the window. From here we can input the desired value of the parameter. See Below;

2. After make the changes, click on the cell and it will give the below message. And then Click Yes to save the changes you made in your Planned Area.

3. Export the change script. Go to Area Management(Planned Area(Export Incremental Script. See Below;

Or you can use the shortcut button to export your Script. See Below;

It will display the following window. You can give the desired path where you want your script to be saved.

In the above image you can see one option, Launch the Script Executer. If you check this option, the CME will take you to the Script Executer window automatically, but you will not be able to copy or edit your script there. 4. Run the script. Right click on your project in the script Executer Window, Activate Project(Break on Failure.The Break on Failure Option will stop the script if it finds error in some command. Otherwise if you choose the Best Effort Option, CME will execute all the commands, skipping the command that contains the error.

\

It will show the following dialogs if successful.

5. We can keep the option of launch the Script Executer unchecked. What it will do is will save the script in a .txt file on your desired path. You can copy that script and run in the MML when you require. When you click export, it will display a link, where your Script is saved in Text file.

4.3 Neighbor Operations4.3.1 Neighbor Review in CMEOpen Cell Configuration Express(BSC 2G Neighbor Cell, you can get the 2G neighbors of that cell.

Note: CME shows the neighbor relations by Cell Index, so it is better to see the neighbors from MML as there you can see the neighbor relations by Cell Names.

4.3.2 Neighbors Configuration16. Right click on Cell Name(Neighboring Cell Configuration Express, and then you can add/delete neighbor relations or change Cell to Cell Parameters.

4.4 Parameters Export

17. Go to GSM Applications Tab(Export Cell Parameter Data

18. Select Cells. There are 2 modes by cell and by NE can be chosen.

19. Select Attributes. Select the parameters you want to export.

20. Select the file type and file path you want to save the parameters, and then click Next or Finish to export the data.

5 PRS OperationsThe PRS is a platform for monitoring and analyzing the performance data of mobile networks, customizing reports, and displaying reports. The PRS is used for the functions such as routine operation and maintenance of the mobile network.

It enables users to aggregate and store data based on multiple dimensions. It supports the long-duration storage and efficient query of data.

It provides various predefined reports, which are used for monitoring and analyzing the operating status of networks.

The PRS enables users to customize KPIs and reports, generate and distribute reports as scheduled, query reports based on multiple dimensions such as object, time, and properties, and manage dashboards, and thus improving the work efficiency of network optimization engineers and operation and maintenance (OM) engineers.

5.1 Introduction to PRSThe PRS supports flexible operations for querying and collecting KPI statistics. You can query the KPIs at object or time dimensions.

Support the KPI analysis. You can query results of KPIs at time and object dimensions without creating a report

Support the scheduled generation and distribution of reports. Without starting the PRS client, you can obtain the reports from the FTP server or the email address.

Support various report formats. A report can contain multiple pages. Each page support different report formats and different filtering conditions, which reduces the user operations.

The PRS adopts the common object request broker architecture (CORBA) that provides a basic data service platform for the system. The services and functions of the PRS are developed and deployed on the basis of modules. In this way, the PRS can quickly respond to your OM requirements.Common Operations of Report Administrators:a. Customizing Required Counters

b. Customizing Busy Hours

c. Customizing KPIs

d. Creating Reports

e. Setting the Correlations Between Reports and Excel Templates

f. Distributing Reports Periodically5.2 Object Group Management

5.2.1 Define Object GroupThe Purpose of defining Object Group is to use them while query of selected cells/ Culprit cells, regions or clusters define in form of object group.

After defining Object Group we can query through Report Management of specific counter at once by clicking Query/ Query by Condition.Here introduce how to define the cell group, the method to define BSC and other groups are similar.

21. Go to Performance Report(Object Group Management

22. Right click GCell, Add(Object Group(Next

23. Select object type. Click Next to select BSC s/ Specific Culprit Cells for cell group analyzing.

24. Provide the name and category of analysis, and then click Next to finish.

5.2.2 Exporting Object GroupThe Report properties of the object group can be exported to get detail of define information in any Gcell Group template. Procedure for exporting is as below.

5.3 Performance Report ManagementAfter the element management system (EMS) collects the data of performance counter data from NEs, the data collection module of the PRS periodically collects the data and saves it in a file, and imports the data in the file to the report database. In this way, the PRS enables you to learn the current network status by querying and monitoring the counter data.5.3.1 Defining ReportWe will make a simple report as an example in this part. The other type reports are similar.25. Right click a root file you want the report belong to. New(Simple Report, and then Next.

.

26. Select the object type you want to define, and then Next.

27. Set the Sub-report type. And input the sub-report name.

28. Select the counters which you need to export in the report.

29. Filter Condition. Choose the Filter Condition as per Report Requirement.

30. Select Top N condition. This makes it easy to get the worst cells.

31. Click OK, and Next, and then set the object that we need to output in the report template. Note: The object we define here is for the template, we can select the mostly using object in this report template. However, we can select the other object as well when query this template.

32. Set the time condition in the report template.

Note: The object we define here is for the template, we can select the mostly using object in this report template. However, we can select the other object as well when query this template.

33. Select the object displaying attribute.

34. Set the basic information: Report name, report directory, and report description.After set the basic information, click Next and then Finish to end.

5.3.2 Excel Template Management

This is one of the best features of PRS. The purpose is to generate graphical report automatically from PRS. We can output the network daily/weekly/monthly report with KPI trend graph or other graphs very easily.This is base on the report template. First select the right report template that we want to make, generate the required graph in excel, and then import the excel template.

35. First query the right repot template which your want to make, and save to your PC.

36. Generate the required graphs based on the downloaded data, after optimize the graphs and format, delete all the data and save as a template.

37. Import the excel template. Right click the report template that just using, Excel Template Management(Set Excel Template, and then input the excel template location, and set export parameters. The excel template is imported.

38. After import the excel template, there is no difference of query results showing in PRS, but if you save the results, you will find that the graphs will be generated automatically.

5.4 Querying Report

In the report management, you can find some report templates by default, and the user-defined report templates.

By double clicking the report template, you can get the results directly.

But if you want to take some more days status, or more objects status, you need to use query by condition. Here shows the steps.

39. Go to Report Management; select the report template that you want to query. Right click the report template, go to Query by Condition.

40. Choose the Objects and time you want to query.

41. Then you can get the required data.

42. Saving data. Right click the main export page and save.

5.5 KPI Analysis

This section describes how to generate a KPI analysis report. To query and obtain the specified data from the report database and to generate corresponding KPI analysis reports, you can set query conditions in real time.43. Go to Performance Report(KPI Analysis. Then you can get the following window:

44. Select the right object type. The mostly using object types are: GBSC, GCELL_GCELL Group, GCell. Select the object type according to the counters you want to analysis.

Then, select the object.

45. Select the counters that you want to analysis.

46. Select the time.

47. Click the, then you can get the results. PRS also can show the graphs which is similar with M2000, by clicking on .

6 Routine Data CollectionFor detailed analysis, we need to take more original data. This chapter is about those original data. There are some parts maybe need the help from the BSS team.

6.1 CFG File CollectionThe CFG file contained the configure information per BSC.Collection method: open LMT or M2000, use the MML command: EXP CFGMML;6.2 OPT Logs Collection
