Detailed Optimization flow

Parameter Audit( If HSPA+ is enabled)

Audit on all Parameters on RNC and Node B Level.To make sure they are consistent with the HSPA+ MOP. Regional tool/script can be used for Parameter AuditRNC/OSS SME Verification of all HSPA+ and HSUPA featuresTo make sure if all the required features in all sites and RNCs implemented as planned.List out the Parameter and Feature inconsistencies and correct themThis step is required first before proceeding with any Optimization activities.

Basic Capacity Check Address the following baseband requirement based on the national capacity guidelines FSMxAdditional T1 or AAVHS scheduler

RET VerificationEnsure RET commissioning is complete RET/Actuator information are in place

Feeder LossFeeder Loss is an important design aspect maintain coverage, capacity & performanceLarge feeder losses will reduce CPICH and the effective coverage area of the cell - Other inconsistent values may affect Power Control & RTWP

Identify sites with more than 3dB loss, using the Feeder Loss Dashboard link given belowOn high feeder loss sites, Utilize latest sweep values, if available to adjust OSS parameters.If high feeder loss is accurate, identify site for possible mitigation for a long solution as belowFeeder modificationRRU implementationNote: These long term solutions will not be implemented during this period of optimization. Feeder Loss Dashboard

Prioritize clusters

Prioritize clusters = (% of bad CQI) * ( HS traffic) -1st priority = quality clusters From high to low traffic -2nd priority = RSCP clusters From high to low traffic

Note: All problem areas in the cluster even with planned new sites will still need to be analyzed and optimized to its full potential

Exceptions

- Bad CQI Sites at coverage edges

For Regions Only2nd Priority1st Priority

Define Problem Areas

Problem Area Major KPI CQI

EXIT Criteria To meet Baseline KPI 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 improvedJustification 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.aspxunder National Performance Reports E2E 3G Leakage Reports

Optimization KPI Reporting OnlyBoomer Index: The UMTS PRACH Delay propagation measurements are compared against the co-located GSM cell radius. A calculation is then performed based on a weighted averageOf HHO distances between the cell and its neighbors. Any instance where the 3G cells radius exceeds the 2G cells radius >= 1.5 is flaggedDL Capacity Index: The Average Power per user is calculated taking into account Voice Power/RL, RT SHO & Cable loss. Any cell where the Avg Power/User is > 27dBm is flaggedUL Capacity :uplink noise rise. Busy hour minus least busy hour

ACTIX ONE/OptPCS AnalysisUsing the drive data from the detailed drive in problem areas, following analysis can be done. DL and UL Coverage Analysis using Scanners RSCP, Ec/Io and UEs TX Power and BLER. Identify weaker coverage areas and provide solutions to improvePilot Pollution Analysis using Scanner data Identify areas of where there is no single dominant pilot. Improve the servers coverage and reduce the interferers. Identify the boomer cells and control them. Identify areas with high SHO overhead and provide solutions to reduce itPilot pollution analysis for data should be done little more aggressively than for voice. Voice can manage with multiple servers, but for the best data performance it needs only one dominant server.DL and UL Data Throughput Analysis In the areas of weaker throughput, correlate it with coverage, and cell capacity KPIs. Identify if it is a coverage / quality issue or a capacity issue. Provide solutions as needed to improve the throughput.CQI target for areas of higher throughput requirement For hotspot areas to achieve better data performance a higher CQI should be targeted (say, => 25). HSPA Cell Change Analysis Correlate the cell change locations with Too Many Server locations. Try to find solutions to reduce the number of cell changes in the driven area.Event Failure Analysis Identify and resolve any drops, blocks, IRAT failures, etc that may have happened in the drive.
