1 Introduction

MCOM is a graphical displaying tool for mobile networks. It is designed to assist Ericsson radio network consultants when working with radio network design and radio network performance improvement. MCOM is built upon the MapInfo application. Because of this MCOM has inherited almost all functionalities that MapInfo provides. Furthermore, all file types that MapInfo supports is also supported by MCOM. MCOM is primarily used in tuning projects were it greatly simplifies the analysis of drive test data by providing an efficient way of displaying the drive test results together with geographical data. The main functionalities that MCOM provides are: • Import of 2G, 3G and LTE site, carrier, and neighbour data into

separate layers.

• Exploring and managing network with Site Editor.

• Cell planning related features:

• Show 2G Interference,

• Show Co-BSIC,

• Show Co-SC,

• Show Neighbours (including IRAT).

• STS – cell’s KPI map.

• Import of TEMS Investigation drive test data and simplified analysis using the TEMS Explorer window, pre-made thematic maps, and tools to visualize Drive-tests.

The scope of this user guide is to explain the functionalities of MCOM version 6.4 and to help a new user getting started. To simplify the process of getting to know MCOM five uses cases are presented in this manual. These five uses cases describe the workflow when doing common tasks in MCOM. The two cases present how to create a new project with site data, import and analyze drive test data. Note that functionalities offered by MapInfo will not be described. More information on how to use MapInfo can be found in the user guide that comes with MapInfo.

4 Use cases – Getting started with MCOM

The following use cases in this sector help to easily get started with the program.

4.1 Case 1 – Create a project with site data

This case is the minimum requirement to get started in MCOM and it is the starting point for the rest of MCOM usage. To start a new project, simply choose File -> New -> New MCOM Project. To create a layer with site information, choose Wizards -> Import Wizard -> MCOM Text File. See 5.1 section for a more thorough description.

Figure 4 Imported site data

Add map layers: different map layers (roads, land areas etc.) can be displayed on the map to get a better overview of the network. This functionality use the MapInfo’s File -> Open .. feature.

Ericsson Internal

USER GUIDE



2010-01-12 PA1

To open a MapInfo layer, choose File -> Open -> Open MapInfo Table5 . After opening the MapInfo layer, the new layer can be add to the map using the Layer Control (right click on the map)

Figure 5 Layer Control

4.2 Case 2 – Import and analyze drive test data

Drive test data can be imported by choosing

Wizards -> Import Wizard -> (select the measurement type)

In this case TEMS DC Drive Test Data has been used; see section 5.5 for further information of the import.

Once the data has been imported, it is possible to check many different things using TEMS Navigator. First, the user has to choose which drive test data to check. This is done by choosing the drive test from the TEMS Explorer window.

Figure 6 TEMS Explorer and TEMS Navigator

• Plot RSCP, Ec/No and Scrambling Code. It is most common to check

the values from Best Server. There may be situations when the user wants to use 2nd, 3rd and etc. servers as well. One situation is to ensure there is sufficient coverage in an area when diminishing Best Server coverage.

• With the filters Coverage Plot Per SC and Best Server Filter, the user filter the coverage from a specific cell. This is very useful when checking e.g. overshooting and azimuth. The difference between Coverage Plot Per SC and Best Server Filter is that the former shows the combined coverage from the top 10 server. The latter shows the scrambling code from a cell only when the cell is best server.

• Potential Active Set Size shows on the map how many potential AS there are along the drive test route. In the RNC the parameter maxActiveSet determines how many active sets are allowed at the same time. The parameter can be set between 2-4 and default is 3. This means that if e.g. there are more than 3 potential AS, then the additional cells will be seen as noise.

For more information about how to use Drive Test Data, see sections 6.2.5.1 to 6.2.5.3.

5 Importing data into MCOM using Import Wizard

In order to work efficiently with MCOM the user usually has to import a lot of information. The Import Wizard function is designed to assist the user when importing network specific information, such as site location, or drive test data. The Import Wizard is found in the Wizards drop down menu and can be used to both import new and to update existing information.

If the user tries to import data that already exists this information will be replaced with the new. This is a convenient way to update information.

Figure 7 Import Wizard main window

There are different import categories, depending on what information the user wants to import and from what program this information has been exported. 1 MCOM Text file (GSM, UMTS and LTE) - Tab delimited text files with

network data (GSM, UMTS and LTE), more specifically site, carrier and neighbour data (*.txt).

2 TEMS RA Drive Test Data (6.0) - Drive test files exported from older

version of TEMS Route Analysis or Deskcat. (*.mif + *.mid)

3 TIW RA Drive Test Data (7.0 or newer) - Drive test files exported from TEMS Investigation 7.0 (or newer) Route Analysis (paired files). (*(top 10).mif + *(top 10).mid and *(90 SC).mif + (90 SC).mid)

Investigation Data Collection. (*.mif + *.mid)

5 TEMS LTE (version 10) – LTE drive test files exported from TEMS Investigation Data Collection (version 10) with Text file export. (*.FMT)

6 STS Import – Import cells’ counters data to display KPI maps.

7 Network dump files – Dump files from GSM and UMTS network.

5.1 MCOM Text file (GSM, UMTS and LTE)

Figure 8 Import Wizard – MCOM Text Files

File location can be either typed in manually or through the Select File dialog box by clicking on the buttons.

The different data can be imported all at once or one at a time. For the very first time, the user needs to import Site Data. The other data can be imported later on.

Sample files are in the installation directory.

Site Data - information such as site coordinates, sectors, azimuth.

Carrier Data - information such as scrambling codes and frequency corresponding to the Site Data. (No separate LTE carrier file. LTE carrier information can be imported with site file.)

Neighbour Data - neighbour relations (GSM, UMTS, LTE and IRAT).

Figure 9 Import Wizard – Layer

The next step is specifying the layer where all the data is stored (site, carrier and neighbour). The data can either be saved in a new layer or in an existing one. If MCOM can find cells from the import site text file in the database, this step is missing, because MCOM automatically determine the destination layer. If site data has already been added, then carrier, neighbour data can be saved to this layer hence the creation of a new layer is not necessary. GSM, UMTS and LTE cannot be mixed in one layer, so two different imports need to be done.

Figure 10 Import Wizard Size and Offset

The size of the font and antenna size for the site data in the Map window are here defined; default is 5 for both values. An offset for x – y axis, measured in meters, is also possible to apply. Antenna and Font size may also have been specified in the imported text file. In this case Use Existing can be checked.

5.2 STS Import

MCOM can import counters’ data of cells and this data can be used to display KPIs’ thematic maps and KPIs’ values.

Figure 12 Import Wizard – STS Import

First user need to select the site layer, because the STS data will be matched to cells of the selected layer.

STS data can be imported from three different file types: • Text file (*.txt) (Tab delimited). • Microsoft Excel (*.xls).

Ericsson Internal

USER GUIDE



2010-01-12 PA1

• Microsoft Access (*.mdb). File header must contains the following mandatory fields: • OBJECT_ID – this column contains the cell names for GSM and UMTS. It

contains the (256 * eNBId + cellId) for LTE. • DATE – MCOM uses this field to determine the date of the measurement

(e.g. ‘090825’ means 25th August 2009). (Note: it is possible to one file contains cell’s counters data for different date.)

• PERIOD – it is the period of the measurement (e.g.: ‘0615-0715’ means a time period from 6:15 am to 7:15 am). (Note: it is also possible to one file contains cell’s counters data for a same date with different measurement period.)

If Microsoft Excel or Access file contains more than one sheet or table, user can select the required table from the list.

Figure 13 STS Import – select table

User can remove any table from the STS import list by right-clicking on it and selecting ‘Remove selected table(s)’.

Following STS settings must be set before starting STS import: • STS Layer – user can separate measurements which were on the same

date at the same period (eg. ‘STS_GSM’ and ‘STS_UMTS’ layers for GSM and UMTS measurement).

• Daily / Hourly statistics – user can decide the type of the statistics data. Note: if the import data’s ‘DATE’, ‘PERIOD’, ‘STS Layer’ and ‘Daily / Hourly statistics selection’ quartet is already exist in the database the import process will delete it from the database and overwrite with the import data. Last step is to open the STS Navigator from the STS menu to display the KPI’s thematic map and labels.

5.3 TEMS Route Analysis data

This import is for users with older versions of TEMS RA. For TEMS version newer than 7, this import should not be used.

Although it will still be working, in order to get the individual SC filters MCOM has to do several queries of the top servers (several columns) thus, making the SC feature very slowly.

The import wizard for this import works the same way as for TIW (see section 5.4 below).

5.4 TIW RA Drive Test Data (7.0 or newer)

Figure 15 below, shows the files that have been generated from the TEMS RA RAN Tuning Report. In this particular case the drive test has been conducted with one scanner and two UEs (MS1 and MS2). In MCOM, the .mif-file is chosen for import, though it needs to be accompanied by its corresponding .mid-file.

The user will choose which equipment to use for the drive test analysis, in this case Scanner, MS1 and/or MS2 (for pilot coverage, the scanner is generally selected).

Figure 15 Files generated by TEMS Route Analysis

The file types top 10 and 90 SC are structured in different ways and though the user can only choose top 10 files, MCOM automatically merges the top 10 with 90 SC. The merge is important since it will speed up the process considerably when filtering drive test data based on SC.

Important: in order for the import to work, the .mif- and the corresponding .mid-files for both top 10 and 90 SC must all be in the same folder.

A cluster name needs to be specified for the drive test as well as the date when the test was performed as shown in [Figure 16]. If there is already a cluster name defined this will be shown in the Cluster name drop down menu.

Figure 17 Drive Test Windows

Once the drive test routes are imported they will be grouped into clusters and dates in the TEMS Explorer Window, as shown to the right in [Figure 17]. By double clicking the route in the TEMS Explorer window, it will appear on the map. To be able to have many different drive tests open simultaneously in the map these have to be placed in different folders by choosing different date or cluster name. The user can e.g. have drive tests from the different clusters or compare the same cluster from different dates.

In [Figure 17] the route has been imported and put into the map. A theme of Ec/No has been chosen.

The windows TEMS Explorer and TEMS Navigator should appear automatically, but if closed they can be found in the View drop-down menu.

5.5 TEMS DC Drive Test Data

These mif-files are exported log files from TEMS Data Collection and many log files can be chosen for best result. The output data is similar as for TEMS Route Analysis data.

As seen in [Figure 18] it is possible to choose different binning options. This is to reduce the amount of data by combining different measured values.

6.2.4.1 STS Navigator

The core of the STS functionality in MCOM is the STS Navigator. The user can view thematic maps based on a set of KPIs that is delivered with the tool. Each theme consists of a formula that is used for the coloring and a label that is shown providing additional information on the KPI. For example the label can show the value of RA_TOT and the coloring can be based on the value of RA_FAIL. Both label and coloring are treated as MapBasic expressions. They can be:

either simple: RA_TOT

or complex: Format$(S_DR_BQ*CNDROP/100,"0")

The coloring is specified by KPI. There are always five ranges but the limits for the ranges are specified by the user who also specifies the color for the given range.

Figure 37 STS Navigator

To show thematic map and labels of KPI, the user must first select the ‘Statistics type’ (e. g. hourly) and STS Layer (e. g. STS_GSM) and date (e. g. Day: 090801 – Period: 0800-0900) that is to be used. This can be selected by the top combo box. Each table is listed containing raw data in the STS database. If the user selects a table that has no corresponding STS MapInfo table a warning message appears:

Figure 38 Warning message about missing STS MapInfo tables

To resolve this problem the user needs to use the STS Organiser to create the MapInfo tables for the selected STS table (see 6.2.4.3 section).

NOTE: STS MapInfo tables automatically generated for the selected Site layer during the STS import.

After the table is selected, the theme combo box becomes active and those cells having STS data attached become green on the site map. The second combo box contains all the KPIs that can be chosen. KPIs that cannot be shown, since the STS table does not contain every counter that is used by the formula, will be greyed out.

For the selected theme you can view the details of the two formulas:

Label: describes the label that is shown on your map when KPI is selected. Note: the label is only displayed if it is enabled among STS options.

Formula: controls the coloring of your cells. The coloring is based on the value in "Exp", also by the ranges given by the range control on the right of the form.

6.2.4.1.1 The different modes of the STS Navigator

By default STS Navigator runs in View mode. This enables the user to view any KPI from the predefined set. Other modes can be selected by clicking the KPI management button at the top of the form. The following modes are available: Add, Edit, Delete and View.

Add mode This creates a new KPI either from scratch (Add/New) or by creating a new theme by cloning the currently selected one. In both cases the Navigator switches to Edit mode.

Note: only one STS MapInfo table can be exist for a given ‘DATE’, ‘PERIOD’, ‘STS Layer’ and ‘Daily / Hourly statistics selection’ quartet i.e. it is not possible to exist for more than one site layer at the same time. User can create STS MapInfo tables with the following options: • Create selected STS MapInfo table(s) – the selected MapInfo tables will

be created or re-created for a selected site layer. User can select more than one STS MapInfo tables and this function can be reached by right-clicking one of the selected item.

• Create All – all STS MapInfo tables will be created for a selected site layer.

Note: re-creating STS MapInfo tables is reasonable if the cell configuration of the selected site layer has been changed. User can remove STS MapInfo tables with the following options: • Remove selected STS MapInfo table(s) – the selected MapInfo tables

will be removed for a selected site layer. User can select more than one STS MapInfo tables and this function can be reached by right-clicking one of the selected item.

• Remove All – all STS MapInfo tables will be removed for a selected site layer.

Restore original PREDEFINED themes and labels: in the install directory there is a copy of the themes delivered by the install package, the name of the file is: "themes.mtx.saved". The content of this file is copied to the model so if you made some bad changes to your thematic map model file then you can restore it back to its original state. UserDefined themes will not be affected.

Convert old MTT file: MCOM 5.5 is released with "themes.mtx",the converted "TEMSThemes.mtt" file. This contains the themes as designed by MCOM developers. As MCOM 5.4 provided with a possibility to change the default thematic map settings and save it to another file MCOM 5.5 offers the conversion of these files to the new format.

Load MTX file: as in MCOM 5.4 you can work with different thematic map settings. You can load another MTX file into the navigator via this menu. This menu can be used when user has a converted MTT file other than the default, or user create a copy of your MTX file with a different name and you would like to work with that.

6.2.5.4.2 Working with PreDefined themes

The subtree structure cannot but the appearance of the thematic map or the label can be changed. Leaves in the tree are checkboxes and by clicking the item it will change its checked state. If it is checked the corresponding thematic map/label is shown otherwise it's removed. The leaf is disabled if the opened layers don't support the given thematic map (e.g. UE related themes are disabled if only Scanner layers are present).

Each leaf has a context menu - accessible by right-clicking on the leaf. The following context menus are available:

Remove: the selected theme is removed from the UserDefined set.

6.2.5.4.4 Working with variables

Variables are used by themes: a theme might contain a parameter that can be controlled by the user, so the same theme can be used for with different ranges. The only example for a variable is "ActiveSetHysterisis". This variable is used by theme "Potential Active Set Size". Changing the value of the variable will change the thematic map too.

“UserDefinedVariables” leaf has a context menu with one item: "New variable". Selecting it "User defined variable" dialog box will open and the name, actual value and default value have to be filled in for the new variable. After a new variable is created it can be referred by any theme.

2010-01-12 PA1

• General

• Queries

• Update query

• Themes

• Note: when changing a PreDefined theme only “Themes” step is available for the user.

6.2.5.5.1 “General” step

The name of the theme and the description can be changed here. The name appears in the tree and the description is shown in a tooltip when the mouse is over the theme in the tree.

Figure 52 Theme Wizard – “General” step

6.2.5.5.2 “Queries” step

Queries can be defined at this step [Figure 53]. First user has to decide if user needs pre-evaluated queries for user’s thematic map. They are necessary if user’s thematic map is based on data from different tables or user works complex calculated fields. User can define several queries but user has to keep the following rules: • User’s first query can be based on any table, even more tables.

However user’s second query has to use the result table from user’s first query, etc.

• The result table of user’s query mustn’t be changed. They are given by MCOM with the following pattern: queryResult_<n>, where “n” is the number of the query.

• “Group by” clause can not be used in the query. If any of these rules are violated the query is not accepted.

Figure 53 Theme Wizard – “Queries” step

At pushing button “Specify query” MapInfo query editor is opened:

Figure 54 Theme Wizard – “Queries” step (Specify query)

If user click “OK” in this editor dialog box then user’s query will be stored in the thematic map theme, otherwise it will be discarded. If the query violated any listed rules then the dialog box is re-opened to let the user change the query.

6.2.5.5.3 “Update query” step

In user’s query user might use user defined variables. When user composes user’s query user has to use literals (constant numbers) but in the next step user can replace constants with variable names. This wizard step contains several tabbed pane. Each tabbed pane shows one of user’s queries created in the previous wizard step.

6.2.5.6 LTE interferer thematic map

TEMS Navigator contains the LTE interferer theme in the User defined folder to show area affected by interfering cells.

Parameters of the calculation are in TEMS Navigator’s User defined variables folder: • RSRP_threshold: LTE_serving_RSRP variable. • RSRQ_threshold: LTE_serving_RSRQ variable. • Minimum_interferers: LTE_minimum_interferers variable. • Margin: LTE_interference_margin variable.

Calculation: 1 Selecting those measurement points where the best server RSRP is

greater or equal to the RSRP_threshold and best server RSRQ is less than the RSRQ_threshold. ("Good signal strength with poor quality.")

2 Minimum_interferers means the number of the allowed servers. For instance Minimum_interferers = 3 means the 1st, 2nd and 3rd servers are allowed and 4th, 5th and 6th servers can be an interferer.

3 Margin is used to decide the possible interferers (in this example they are 4th, 5th and 6th servers) are taken account as an interferers or not. Margin is used for the RSRP value. Eg. if the 4th server is in the margin the interferer value will be 1 for the given measurement point, if the 5th server is also in the margin the interferer value will be 2, if 6th server is in the margin the value will be 3.
