1 Introduct ion
This document contains a list of all the required information and data to be collected on
Ericsson UMTS infrastructures in preparation for the installation of the Mentor optimization tool.
The information and data required includes the following:
Network configuration (detailed in section3)
o Ericsson Network Topology file (XML format)
o Antenna and sectors physical location, profiles, and parameters in delimited format
(internally known as Schema format)
o GSM Network Topology (Optional, for running an IRAT optimization and displaying the
GSM layer)
UMTS logs and counter data (detailed in section4)
o GPEH logs
o Counters file (XML format)
o RBS logs
When preparing to set up Mentor in a network, we usually recommend starting by creating the
network configuration, followed by a sample data collection.
Section 2 outlines a setup checklist, which should be used as a first step to facilitate
efficient installation and configuration.
The following sections of this document provide a more in-depth description of the required
data sources, and the manner in which they can be obtained.

3 Detai led Descrip t io n of Requi red Infor mation
and Data
3.1 Netw ork Confi gur at ion Data
The sources for network configuration data are:
o A predefined set of Network Topology files exported from the Ericsson OSS in XML
format.
o Textual files, including complete information required for physical sites and soft
parameter configuration, depending on availability (Schema Format).
IMPORTANT Mentor includes an automatic wizard that generates most of the textual files
required for its operation, based on the data commonly available in the service provider
environment.
3.1.1 Er ics son 3G Netw ork Topolo gy (XML for mat)
There are several options to generate the Ericsson XML configuration files. Many variants exist,
which will generate different content within the XML files.
The Mentor product makes use of an elaborated configuration file, which contains all of the RNC
and NodeB parameters. Using this type of file enables Mentor to identify and warn about
configuration problems, use the RBS counters as well as create an accurate model of the
network.
The network topology dump might already be activated in the network. Follow the procedure in
section3.1.1.1to verify whether the dumps have already been created, or run them directly from
the UNIX machine. The procedure described in 3.1.1.2 uses the OSSRC to generate the
configuration files.

3.1.1.1 Generating the XML Configuration Using Scripts
First check if the configuration files are already available in the following directory:
/var/opt/ericsson/nms_umts_wran_bcg/files/export
You can use the UNIX scripts in the OSS that periodically generates the XML configuration file.
The shells script is called start_rah_export.sh , and is located in the following directory:
opt/ericsson/nms_umts_wran_bcg/bin/
Further information can be found in the ALEX system through:
Bulk Configuration System Administrator Guide 1/1543-APR 901 550/2 Uen E Bulk Configuration General and Transport User GuideBulk Configuration System Administrator Guide
3.1.1.2 Generating the XML Configuration File Using the OSSRC
IMPORTANT:Because of an internal Ericsson issue, we recommend exporting the entire
network configuration and not only a specific RNC. See chapter 3.1.1.3 for an explanation
as to how to analyze the results.
1. Launch>>Applications>>Ericsson>>OSS Common Explorer.
2. Ensure that the combo box under WCDMA menu has the value RNC/RBS.
3. Right-click Root(red icon) -> Export configuration. Can be performed up to RBS level.
4. Change the file name (optional).
5. Select the Both radio and transport topologyoption (3rd radio button).
6. Click Nextand then Finish.

3.1.1.3 Working wi th Ericsson XML files and checking their validi ty
Ericsson OSS will not export the NodeB information when only exporting a single RNC.
TEOCO recommends verifying the data using an external XML reader, such as XML Marker.
(http://symbolclick.com/download.htm)
When loading a single RNC xml dump without the NodeB information, you will see a picture
similar to the one listed below. Under the main SubNetwork folder, there is an individual
SubNetwork for each RNC.

An XML dump that contains NodeB data will include additional information under the RNC
SubNetwork such as ExternalGsmCell, etc.
Sometimes, it is not possible to open a large XML file with an XML editor (usually over 750MB).
In this case, use TEOCOs scripts to divide the file into the different RNCs, or manually cut-out
RNCs between the two XML directives:

3.1.2 GSM Netw ork Topol og y
Note:This is an optional input used for IRAT optimization and for displaying the GSM
topology.
A special retrieval procedure can be used on the OSS for each underlying GSM vendor.
Moreover, a physical topology file is required, similar to the one needed for UMTS.
TEOCO can provide detailed documentation on how to perform this operation, if required.
For example, for Ericsson GSM networks the following standard procedure should be
followed (additional variants are available, depending on the specific versions). This is only an
excerpt from the full document.
Retrieve the required BSS network configuration file from the Ericsson OSS, using the Cellular
Network Administrator (CNA), by running the following commands:
Overall Network configuration:
cna_export NW = all, MSC = all, MSC_REF = none, BSC = all, BSC_REF = all, SITE = all,SITE_REF = none, CELL = all, CELL_REF = all, OUTPUT=AllParameters_YYYYMMDD.txt
Foreign cells:
cna_export NW = all, FCELL = all, FCELL_REF = all, OUTPUT=foreign_HO_YYYYMMDD.txt
(where: YYYY year, MM month, DD day)
3.1.3 Antenn a and Secto rs Physi cal Loc at ion , Prof i les, and
Parameters in Del imi ted Format
The physical parameters of the network, such as the sector and antenna location, and the
antenna profiles, might not be available through the OSS configuration dump.
Most of the required physical configuration of the network can be derived from network planning
tools or from customer-self-maintained databases with the most updated network configuration.
Mentor defines a set of textual files that should be available. These files are:
Antenna file - includes the physical configuration of each sector. See section for the file format.
Antenna profiles antenna-pattern data files
Mentor also requires an updated Terrain file.
In contrast to planning tools or other configuration sources, Mentor requires only active sector-
carriers. Sectors that are inactive during an analyzed period should be marked as inactive in
the antenna files.

All soft parameters may be defined in this file, but will be overridden by the Network Topology
files. We recommend that the latest Network Topology files be used to update the Schema
format file and to identify any inconsistencies, such as missing or unnecessary sectors.
3.1.3.1 Antenna File
The antenna file (in tab-delimited text format) includes the physical configuration of each
sector, including:
o Location data (i.e., coordinates, height, and so forth)
o Antenna characteristics (i.e., height, azimuth, and so forth)
o Physical constraints
o Network topology
The antenna file must include all sectors selected for optimization and all sectors in the
guard-zone area where optimization is not performed . We recommend that all sectorswithin two tiers of the selected sectors be included.
The Antenna file fields are described inTable 1:

4 Ericsso n Logs and Stats
The General Performance Event Handler (GPEH) files contain periodic and event-triggered
mobile and NodeB reports, which enable Mentor to model the network.
The following procedure should be used to define GPEH and Stats profiles, generate them, and
collect them for use in Mentor.
4.1 GPEH Log Collect io n and Setup
4.1.1 GPEH Prof i l e
For the GPEH files to have the necessary information required for Mentor to operate, the
correct profile must be defined in the OSSRC. The following procedure can be used to set theprofile:
INPORTANT - The following parameters must be defined correctly:
UeFraction=1,000
GPEHfileSize=60,000
Mentor can operate with reduced values for these parameters. To define a different set of
values, please consult TEOCO support.

4.2 Stats File (XML)
This 15-minute interval file contains the RNC counters for all the network elements. Usually the
counters are already correctly defined and enabled in the OSSRC.
If for any reason the RBS counters are not configured for collection, please refer to the list in
section4.2.2for the list of counters. It is important to add them for proper HSPA analysis.

The Template files include the GPEH events to record, counters to record, and network areas for
both.
If the template files are used, they must be activated in the Data collection subscription profiles
in the OSS.
4.4 RES Act i vati on and Pro pert ies (WMRR)
Note:This is an optional data input, which is rearly used with current customers.
Mentor can utilize the additional information provided as periodic messages in the GPEH logs.
Activating the periodic messages will increase the GPEH data file size.
If the messages are activated, TEOCO recommends defining EcIo, RSCP, and UeTxPower as
parameters to be reported in the periodic measurements.

4.4.2 RES Resul ts
Activating RES in the network will result in additional periodic-measurement reports in the GPEH
files.
For example, the following sample of a GPEH file includes RES data. As can be seen by the time
stamp, each report is provided in 16-second time intervals.
In the following case, it can also be seen that two sectors were serving the terminal.
4.5 Folder Str uct ure fo r GPEH and Count er Fi les
For OSS data GPEH and counter files to be processed most efficiently by Mentor, the folder
structure should be maintained as follows:
Under the parent folder, create two folders. One should be named logs, for the GPEH
files, and the other KPIs for the counter files (including the RBS counters). It is VITAL that
these folder names are used, as Mentor looks for these names when processing the files.
Under each of the two folders, create a folder for each day of recordings, named according
to the date, in YYYYMMDD format. Diverting from this format will increase Mentors file
processing time.
Under each date folder, place the appropriate recording files for that day. The files can be
placed directly under the date folder, but we recommend opening a subfolder for each
RNC/RBS, as shown in the following example.
