Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Ericsson Confidential Post-Launch Tuning Cluster Scope Purpose: Perform Post launch Cluster tuning after 14 th December 2005 Launch Pre-Requisites: Cluster needs to be at 90% level plus 60% surrounding sites Duration: Post-Launch Complete Cluster Activities 30 days/cluster (medium cluster market) or 34 days/cluster (large cluster market) Post-launched activity for selected tuned clusters 26 days/cluster (medium cluster market) or 31 days/cluster (large cluster market) 5 days for the IRAT UMTS EDGE border clusters drive 4 Drives per Cluster for tuning. 7 Extra drives for 3 selected clusters and One UMTS EDGE border cluster drive Cingular must arrange for Remote Electrical Tilt (RET) teams to be provided to complete changes to sites in a cluster that require downtilt changes within 3 days of drive analysis being completed Estimate 70% of a clusters sectors will need RET adjustments after the first tuning drive Average 42 sectors (14/day) in a 60 sector/20 site cluster Estimate may be revised based on IT feedback OCNS Calibration for selected tuned clusters: 1.For OCNS Calibration clusters will be divided into two different morphologies, Site density and Site configuration 2.Based on step 1 results, OCNS calibration will be performed. This will help in reducing the OCNS drives in Selected clusters

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Ericsson Confidential Explanation: Un-tuned Clusters: –All clusters for Post launch tuning activities will be considered as un-tuned Selected Tuned Clusters: –3 + 1 Clusters from each market will be selected after the tuning activities. Selection will be based upon the following Speech Dropped Call Rate performance criteria 1.Best Performer 2.Medium performer 3.Low performer 4.IRAT dirve at the edges of the UMTS coverage area (see the picture below) HSDPA loaded Drive: –CS OCNS calibration values will be used

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Ericsson Confidential Post-Launch: Un-Tuned Clusters Activities/ Flowchart Scope Timelines Drive (2 days) Drive Analysis (5 days) Implement changes (3 days) Drive (2 days) Drive Analysis (5 days) Implement changes (2 days) Drive (2 days) Analysis + changes (4 days) Drive (2 days) Analysis (3 day) AMR 12.2k and PS R99 unloaded Drive #1 Site Testing Note: 2 days is the average drive time for a cluster. Some clusters in Houston and San Diego are large and 3 days would be needed for driving. *25 days/cluster (medium cluster market) or 28 days/cluster (large cluster market) not including the optional drive **No OCNS Calibrated load. Load for each cluster per market will be provided by Performance Team. 30 days/cluster (medium cluster market) or 34 days/cluster (large cluster market) AMR 12.2k and PS R99 unloaded Drive #2 AMR 12.2k and PS R99 loaded** AMR 12.2k and PS R99 unloaded Drive #3 (Optional)*

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Ericsson Confidential Post-Launch Activities/ Flowchart for 3 Selected Tuned Cluster Note: 2 days is the average drive time for a cluster. Some clusters in Houston and San Diego are large and 3 days would be needed for driving. 22 days/cluster are needed (assuming drives are performed nighttime and data analysis daytime) ScopeTimelines IRAT Drive 10 days for OCNS cluster calibration (drive + data analysis) AMR 12.2k (drive + data analysis) PS 128K I/B (drive + data analysis) HSDPA (drive + data analysis) IRAT

6 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Ericsson Confidential Cluster KPIs to be Reported Purpose –To show the tuning progress and assess readiness of clusters for the CA Frequency of Reporting –Cluster KPI reports will be reported weekly, as analyses are completed

7 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Ericsson Confidential Reporting KPI Per Drive AMR 12.2k Drive: –BLER –Dropped call Rate –Accessibility Rate –Call Set up Time –Successful RAB Assignment Rate –Successful RRC Connection Set Up Rate –Successful Active Set Update Rate –Successful Radio Bearer Reconfiguration Rate
