i am working on a Network with Nokia, Ericsson and Siemens vendors. i am trying to unify main KPI on a netwrok level ( combining all 3 vendors) but i found many differences between each vendor’s KPIs ( radio kpi), Nokia taking into account System point of view and Ericsson taking Customer point of view KPIs. i have a question especially regarding SDCCH Drop Call in Nokia. we experience high SDCCH drop in nokia area compared to Ericsson or siemens. and 99% of SDCCH are due to radio reason ( SDCCH Fail Radio cause). the problem is that this includes also failures before even the SDCCH is completly assigned to MS ( before getting EST IND from MS).
Do you know any other Nokia formulae that counts only drops after Establish indication
thanks for support and help
