【正文】 PLE TECA F1: cell update procedure Cell update counter ? Cell update KPI ? Cell update success rate = Cell update success/Cell update request ? Overall Counter ? Cell update request ? Cell update success ? Cell update cause counter ? Cell reselection ? Periodical cell update ? Uplink data transmission ? Paging response ? Reentered service area ? Radio link failure ? RLC unrecoverable error Contents UTRAN Call Setup UTRAN Call Drop UTRAN Mobility Management Traffic Management Algorithm Management Traffic Counter ? User number ? RRC state based user number ? Cell DCH, Cell FACH, Cell PCH, URA PCH ? Traffic class based equivalent user ? Conversational ? Streaming ? Interactive and background ? Cell throughput ? Directional counter ? Cell uplink throughput ? Cell downlink throughput ? Traffic class based counter ? Conversational, streaming, interactive, background ? All supported bandwidth Traffic Counter ? Iub bandwidth utilization ? Common channel (RACH, FACH, PCH) volume ? Traffic class based service volume ? Uplink and downlink volume ? OVSF code utilization ? SF based ? SF=4 ? SF=8 ? …… ? SF=512 ? RTWP and Carrier Power ? Cell RTWP ? Transmission Carrier Power Contents UTRAN Call Setup UTRAN Call Drop UTRAN Mobility Management Traffic Management Algorithm Management Algorithm Counter ? DCCC ? Overall counter ? Channel switch request ? Channel switch success ? DCHDCH channel switch counter ? Channel switch success (DL Bit Rate upgrade ) ? Channel switch success (DL Bit Rate degrade ) ? DCHFACH/RACH channel switch counter ? Channel switch success (To mon channel) ? Channel switch success (From mon channel) ? AMRC ? Uplink AMR control counter (degrade) ? Downlink AMR control counter (upgrade) ? CAC ? UL Admission deny counter ? DL Admission deny counter Appendix: Nastar KPI Analysis Routine Define monitor area: RNC group or cell group Query Performance Item Query Top N cell list Query related item Import raw data Define cluster Select Issue Find out trouble cause Raw counter Analysis Select performance analysis issue Query metric item, find the fault or trouble Query TopN cell list in predefined cluster, find the worst cell or cell group Query related metric item in the specified worst cells Query and find out the fault or trouble cause Analyze raw counter if necessary Import performance counter from NE M2022 ? Step1: Check RRC metric item by “RRC setup analysis” issue RRC Setup Rate is lower Appendix: Nastar KPI Analysis Example ? Step2: Find the worst TopN cell list in former cluster by “Forward” Appendix: Nastar KPI Analysis Example ? Step3: Find the worst cell in TopN list Appendix: Nastar KPI Analysis Example ? Step4: Query RRC reject cause in specified cell by “Forward” Appendix: Nastar KPI Analysis Example ? Step5: Find the RRC reject cause in the worst cell Appendix: Nastar KPI Analysis Example
