RN31572EN20GLA1 KPI Overview 21 Soc Classification level 21 © Nokia Siemens Networks RN31572EN20GLA1 Principles of performance measurements (1/2) Poor CSSR could be a result of • Poor coverage or dominance or interference issues in Radio interface • Capacity issues in Radio or Iub interface • Configuration issues in WBTS (parameters or HW) CSSR is essentially RRC Setup Success * RAB Setup Success (or successful PS session setups in case of PS call) CSSR covers all the steps from the initial RRC connection request from the UE to the network, through the RRC setup phase and the RAB setup phase, and until user data is starting to get transferred. The CSSR formulas are for different traffic classes like: • CS voice calls (RNC 565 f) • CS video calls (RNC 566e) • PS RT Streaming Calls (RNC 575 d) • PS NRT Calls (Interactive & Background) (RNC 576d)
  22. 22.

The UE has made a new RRC connection via another cell and Attempts-counter is updated in the new cell for the new attempt. ))____( )____(( * )_________ _______ _______ ______ ______( )____ _______ ____ ______ ______((*100 _ VOICECSATTSTPRABsum VOICECSCOMPACCRABsum CALLEMERGREJSTPCONNRRCCONVMTRELACCRRC CONVMORELACCRRCEMERGENCYRELACCRRC EMERGENCYREPATTRRCCONVMTREPATTRRC CONVMOREPATTRRCATTSCALLEMERGENCY ATTSCALLCONVMTCATTSCALLCONVMOCsum CONVMTRELACCRRC CONVMORELACCRRCEMERGENCYRELACCRRC FAILSCALLEMERGENCYATTSCALLEMERGENCY FAILSCALLCONVMTCATTSCALLCONVMTC FAILSCALLCONVMOCATTSCALLCONVMOCsum CSSRAMR −− −− −− −+ + − −− −+ −+ − = RRC part RAB part
