BSS Counters Measurement Tables

How to activate tables?  These

can be activated at BSC level or can be activated at NetAct level.  If they are part of optional feature, the feature needs to be present on the PRFILE of each BSC. The parameter related to the feature needs to be activated.  Start date and End date needs to be defined.  Start time and End time of each day of the week needs to be defined  Period needs to be defined Set parameter in PR_FILE (WOC): ZWOC:10,65,FF; Set measurement (TPM): ZTPM:,:, ,

:; ZTPM:MEASUR,CHAN_FIN:ALL,0 –0 –24 –0,60:DB1=0,DB2=8; Start measurement (TPS): ZTPS:MEASUR,CHAN_FIN; *usually this is done by bcs engineer

BSS Counters Measurement Tables Measurement

reporting interval to each measurement can be unique.  – 15min, 30min, 1hour etc… During optimization these different measurement reporting intervals should be verified to support need of optimization activities. Note! Any

changes to measurement interval should be agreed with OSS administrator to avoid any overload situation in OSS.

 How

to check that all data is available in OSS Can be checked running Reporting Suite reports  – Some KPIs are using several tables, so if all data is not available, results might be strange.  – If you want to check all data, all tables should be run

BSS Counters Numbering

Counter = XXXYYY where XXX = measurement table YYY = counter number in measurement table Example: counter 001001 or c1001 XXX = 001 = c1 = traffic measurement YYY = 001 = SEIZURE ATTEMPTS WITH BUSY SDCCH

KPI Formula Sample

Indicators (PIs) and Key Performance Indicators (KPIs) are created based on data in counters.  – Tables must be activated and data must be available in OSS  Performance Reports are created based on KPI analysis
