Getting Started with Megamon Analysis in Xeus ProOverview: Nokia Siemens Network (NSN) Megamon is a Performance Recording feature that can perform trace logging function. This feature enables you to 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. 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 help file found after downloading Xeus into your pc for the full list of XIF format description. XIF Parameter CellId Description The unique Cell Identity/Name of the cell e.g. G1001A. Note: Xeus 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 The Site Id of the cell e.g. D1001. Note: Site Id will be displayed as label for cell in the map Longitude of the cell in Float format e.g. -121.23328. Mandatory field Latitude of the cell in Float format e.g. 30.12312. Mandatory field Direction of the cell in Degree unit Mandatory field RNC Identity Note: RncId-Cid pair allows matching of WCDMA Cell network data to the site data in Xeus database WCDMA Cell Identity Note: RncId-Cid pair allows matching of WCDMA Cell network data to the site data in Xeus database Table 1 – XIF parameter format SiteId Longitude Latitude AntDir RncId CId 1 Figure 1 – Sample of XIF format 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,0A340,0A339,0 D9DA,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” 2 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. 5. Mandatory message- > rak_modify_rnc_param_s Megamon Importing: 1. Create a new project 2. Create a complete site data using xif format and import into Xeus. Uncheck “Import Carrier & Neighbor data” as the neighbor data will be imported by the network dump later. Figure 2 – Import site data in XIF format 3. Import latest Nokia WCDMA RAML XML file. Match cell using “RncId + Cid” with the previous imported XIF format site data. 3 Figure 3 – Import Nokia WCDMA RAML XML file 4. Import NSN Megamon log. Multiple Megamon log can be imported into the project. Figure 4 – Megamon log importing 5. Click “Next” and check on the option of GeoAnalysis if user wants to geo-locate calls and events. Figure 5 – Megamon General Settings 4 6. Click “Finish” and the Megamon log will start parsing. Figure 6 below shows an example of the Megamon analysis start page.
