Transcript of Tampa HSPA+ Optimization Market Kick Off
HSPA+ OptimizationTampa Market
Pre-opt start list• RET report • Feeder Loss values audit• Commissioning/SCF/FTM config audits• BFD/AAV audit• Capacity audits and report from capacity team
Cluster Identification process (planning and performance) including asset analysis, liberty server CQI reports etc
Optimization process using KPI and drivetest.• KPI analysis• Using actix for KPI and drivetest analysis• OPTpcs
Change requests1. Process for identifying and approving the requests needs to be worked out between the local
market engineers and HSPA+ assigned resources1.To be approved by t-mobile employee
Result verification against the reported CQI2.Exit criteria
General HSPA+ Optimization
Flow of Optimization work
Flow of Optimization work – contd.
• Region• Market• Market to submit &
Region to validate/approve
Responsibilities
EXIT Criteria – To meet – Baseline KPI
Sl. No. KPIs Exit Threshold (Market wise)
1 CQI Number of Cells with >5% in CQI 0 to 10, to reduce by 80% AND Market wise CQI above 10 > 98%
TPIM KPIs1 Voice Access Failure rate (%) <= previous round value2 PS Access Failure rate (%) <= previous round value3 Voice Drop Rate (%) <= previous round value4 PS Drop Rate (%) <= previous round value5 Actual MAC-HS Cell Thpt (Mbps) >= previous round value6 Voice Traffic in Erlangs >= previous round value7 HSDPA Pay Load-RLC layer (MB) >= previous round value8 3G Leakage (% of 3G calls ending on 2G) <= previous round value9 % of 3G initiating calls on 2G (CDR Based) <= previous round value
• All entry & exit criteria should be measured on a one week average for comparison• The same criteria will be used to monitor the cluster performance during optimization• Above listed TPIM KPIs are expected to be maintained or improved• Justification needed for 8&9 if value degraded by 2% ( to be validated from trial)
Note: These KPIs(1-8) are available in TPIM under the content browser by running the report “NSN HSPA KPIs”. TPIM (9) can be found: http://dev.reportcenter.internal.t-mobile.com/Reports/Pages/Folder.aspx

Support Needed
1. OptPCS tool access
2. Actix access
3. Massive commisioning file collection
4. Drivetest team (TEMS)
5. Administrator right for PC

Questions/Comments
Request for a new combined report containing all the KPI related to improving CQI (CL, UL Noise Rise, Overshooting index…) along with Bad CQI distribution.
3G leakage KPI needs clarification in terms of voice or data or both 3G leakage is market level, daily KPI. It would be good to have cell level
report on weekly level as well. Difference between Sheet2 and Sheet3 is not clear
Aggregation period for establishing the acceptance KPI
Cable loss report is daily level. It would be good to have it at weekly level as well
In TPIM Custom NSN HSPA Report, HSDPA Traffic Volume is not showing up
