INTRODUCTION Traffic Measurement Recordings are available on most major vendors OSS system. This means that each vendor will have their own recording function that might vary from one vendor to another. This extremely powerful data source consists of detailed event and measurement data of a significant portion of your users live traffic. By running selected optimization tasks in Xeus Pro, optimization engineers can drill down quickly to optimize known areas with quality issues, and analyze the recording results to pin-point parts of the network these issues are coming from.

GPEH

Ericsson General Performance Event Handling (GPEH) is the traffic measurement recording found on

Ericsson WCDMA networks. This performance recording function consists of two types of recording,

User Equipment Traffic Recording (UETR) and Cell Traffic Recording (CTR).

CHR

Call History Recording (CHR) is the traffic measurement recording found on Huawei networks. This trace

logging feature is available in both Huawei RNC and NodeB networks. Xeus Pro utilizes the Performance

Call History Recording (PCHR) data from the call history recording to help users to perform further

analysis.

Megamon

Megamon is the traffic measurement recording found in Nokia Siemens Network (NSN) networks. Xeus Pro helps users utilize the collected Megamon data such as cell information, radio measurements and call messages to perform further analysis on calls, events, cells, phone models & user IMSI.

IMPORTING TRAFFIC RECORDING FILES Traffic recording data is best analyzed when users have a complete set of network data. It will provide

complete analysis for neighbor optimization. Users can refer to Aexio Xeus Pro 2012 Quick Guide for

more information about importing network data.

Ericsson GPEH/UETR/CTR log

You need to ensure that you have the following before you import GPEH/UETR/CTR data:

1. Network data (preferably Ericsson Bulk CM).

1.1. Network Data accepted for GeoAnalysis (Ericsson Bulk CM or Ericsson Kget log file only)

2. Log file format

3. Log file set(s) contain mandatory messages

Refer to Appendix 1(a) for pre-requisites for GPEH Analysis. Refer to the Appendix 1(b) for Ericsson

GPEH Recording Steps. Refer to the Appendix 1(c) for GPEH Recording Scenarios.

GPEH/UETR/CTR data is best analyzed when you have Ericsson Bulk CM. If you are performing

GeoAnalysis, ensure that the network data selected is Ericsson Bulk CM or Ericsson Kget log file.

Huawei CHR log

You need to ensure the following before you import CHR data:

1. Huawei Network Data

2. Correct log file format

Refer to Appendix 2 for pre-requisites for CHR Analysis.

Nokia Megamon log

You need to ensure the following before you import Megamon data:

3. Megamon Network Data

4. Correct log file format

Refer to Appendix 3 for pre-requisites for Megamon Analysis.


Now, follow these steps to start importing your Traffic Recording log files:

1. Go to File > Import and Export > Import Traffic Recording logs (Ericsson OR Huawei OR

Megamon)

Figure 1 Example of How to Import GPEH/UETR/CTR Logs

2. Click on Add Files button and select the files.

Please note that;

a. For GPEH logs, select the files which includes file 0.

b. For CHR logs, if the file name is highlighted in red, this indicates that there might be a

possibility that the selected log file does not contain PCHR or UCHR log file.

3. Select Add Folder, if users have placed the log files in a folder.

4. Browse and select files.

Please note:

Single parsing of traffic recording files has been implemented (Previously, multiple parsing allows) to

the improve speed in Xeus Pro application.


Figure 2 Example of selecting Ericsson GPEH/UETR/CTR Log Files

5. Click Next button to continue.


Ericsson Logs

1. At General tab, set the Time Offset

according to your time zone.

2. If you are performing GeoAnalysis,

ensure that you tick on Enable

GeoAnalysis. Note: Ensure that the

loaded network file contains RRC

Measurement Report and NBAP Radio

Link Setup Request messages.

3. Click the Filters tab to set the filter

options. Select a Filter Template and

click "Settings" button to set to the

"Messages Filter" and the "Call End

Filter". Click "OK" button to save the

changes made at GPEH filter and for you

to reload the same settings later.

4. Select the Settings tab to edit

thresholds.

Huawei Logs

1. Select the Filter option by ticking on the

required checkbox.

2. Click on Settings tab, if you wish to

3. Click Finish and wait for the parsing to complete.

Once the progress bar completes, there will be a notification which says 'Parsing completed successfully'

and it will display the parsing duration. If parsing is successful, users are ready to analyze your Traffic

Recording data.

Please Note:

For CHR, if the parsing exceeds 1 hour, it will automatically prompt an error message. Xeus Pro can only

parse the log file that contains Performance Call History Recording (PCHR). If the parsing does not

contain the PCHR data, an error message will appear to notify the user of the parsing error.


START PAGE ANALYSIS Network recording database loads automatically together with its summary at the Project Explorer after

parsing. Loading the database will also automatically load the Start Page.

GeoAnalysis GeoAnalysis is an estimation of the calls or events based on a geographical location. This feature enables

users to generate various plotting scenarios based on the estimated geographical location for the Traffic

Recording calls. Users can also analyze normal and abnormal events within the dimension of the

estimated location. Xeus Pro uses several propagation delay and mobile triangular calculation to

perform location estimation.

Please Note:

Geo-location method uses cells coordinate (longitude & latitude) instead of site id for better accuracy.

Plotting

Important: For R11 and above, please ensure that the file name ha UCHR or PCHR. File with CHR string alone does contain the performance call log and not supported in Xeus Pro.

3.2 Enable the CHRs Field If one of the fields is not enabled in the CHRs, use the following command to enable it: 1. In the LMT tool, execute the command SET CHRRNCCTRL (R10) or SET UCHRCTRL (R11) in

the Command Input field.


2. Click the SELECT ALL check box in the Type option drop down lists. 3. Run the command through a batch file only:

Appendix 3: PRE-REQUISITE FOR MEGAMON ANALYSIS

1. Site Data Users need to import the site data by XIF/TEMS Cel-file/ MCOM file format first before the importing of the Nokia WCDMA RAML XML file. Table 1 below shows some of the mandatory fields in creating a XIF format site data. Please refer to the Xeus Pro help file found after downloading Xeus Pro into your pc for the full list of XIF format description.


CellId The unique Cell Identity/Name of the cell e.g. G1001A.

Note: Xeus Pro does not accept two records with SAME Cell Id. Any duplicate

cell Id will be renamed with additional suffix e.g. G1001A_1.

Mandatory field

SiteId

The Site Id of the cell e.g. D1001.

Note: Site Id will be displayed as label for cell in the map

Longitude

Longitude of the cell in Float format e.g. -121.23328.

Mandatory field

Latitude Latitude of the cell in Float format e.g. 30.12312.

Mandatory field

AntDir

Direction of the cell in Degree unit

Mandatory field

RncId

RNC Identity



CId

WCDMA Cell Identity






2. RNC Network Dump User can import the WCDMA site configuration and neighbor data by importing the Nokia WCDMA RAML XML file.

3. Megamon .MGA Log File Initial Megamon log files collection 1. Start Megamon -> Setup -> Select Connections

Check with equipment vendors and make sure the control connections settings are set correctly.

2. Setup -> Select Output files a. Set the output file directory b. Do not check on the output type as the output file extension will be in *.MGA

binary format. c. Set the time based to 10 min d. Check the PC HD space and apply conditional items removal accordingly e. Do not check on any options settings f. Set the format of the output filename as your preference. Advisable filename to

include network element with year, month, date, hour, minute and seconds. 3. Setup -> Select Filter condition

Check if there is Telecom filter with condition of SR:(OFAM=4FD,507,508,509)AND(NOT(NUM=0001,0002,8037,8038,0D5BA,0A340,0A339,0D9DA,0D5B8,0AB2B)), if no, create a new filter with condition.

4. Action -> Select Get Units a. Only check on the ICSU units b. Set all ICSU with Telecoms filter & leave Via column settings as N/A


c. After click Set Filters then confirm Status=OK-> Click Start mon d. Check output directory and find the log files

e. Click Stop once the Megamon log collection is done.
