5 Gladiator G-Station Supports: GSM, UMTS/HSPA and LTE, WiMAX, cdma2000 and EvDO Supports major drive test vendors: JDSU-NiXT, ASCOM- TEMS, Anite-Nemo, Accuver- XCAL,R&S-SwissQual, PCTEL, etc Selected by Vendors and Operators as a standard post processing platform G-Station rich set of visualization and analysis capabilities

6 Toolbox organization Analysis in a toolbox Three types of analyses Area (coverage, interference, missing neighbor) Examine larger area Work with binned data Event (block call, dropped call, handoff) Examine various events during the call Reports (various KPI stats) Summarize overall stats for the drive Analysis are single click with a detailed help and analysis algorithm explanation Note: Organization of the analyses is the same for all technology toolboxes Required data sources: Drive test data and system reference file Optional: Configuration dump (CM) Main modules: Standard Frame and State Machine Optional: CDC

7 RF Optimization Coverage Findings: DL poor coverage, coverage edge, interference, antenna null UL poor coverage and interference Outputs Map indicating problem areas and problem sites Report ranking problematic cells

8 RF Optimization Pollution Findings: Isolate coverage issue from pollution issues. Identification on pollution areas with: Excessive coverage overlap (Too many servers) Non dominant server (Lack of dominant server) Outputs: Map indicating areas with Coverage issues and areas with Pollution issues. Report with overall coverage performance summary. Report ranking problematic cells for optimization. Help minimizing interference and improving quality

9 RF Optimization Missing Neighbor Findings: Determines missing neighbors based on phone/scanner data and system Determine Over shooters based on phone/scanner data and system Outputs: Map indicating location of missing neighbors Map indicating location of Over shooters Report ranking the missing neighbor relationships Report indicating the Top 10 Over shooters Help minimizing Drop call

10 RF Optimization Cross Feeder Findings: Identify swapped sectors Identify cells with coverage outside main lobe. Output: Map with all the areas where coverage is outside main lobe. Map with highlighted cells that are having coverage outside main lobe. Report with detail information per cell

11 RF Optimization Throughput Findings: Identify areas with poor throughput Correlate throughput performance with RF coverage and quality. Output: Map with all the areas with: Poor Throughput Poor RF Mismatch between Quality and Throughput Report with throughput statistics.

12 RAN Optimization Layer 3 Events Findings: Analysis of both CS and PS side Based on Layer 3 message flow Identification of every abnormal events (Failures) Output: Produces detailed report with call stats KPI s Investigation of the abnormal failures to determine the root cause

13 RAN Optimization Application Events Findings: Documents events on the application layer Evaluates performance of each individual application Outputs: Map showing data events performance Reports with statistics of the Application events RF investigation on the abnormal events.

14 RAN Optimization Troubleshooting Findings: Check the root cause for every abnormal events (Failures) Output: Produces detailed report with reasons for the abnormal event Check for RF coverage issue like: Poor coverage Interference Swapped Sectors Missing Neighbors Overshooting cell Etc

15 Reports - phone Used for: The reporting may be done on the entire data set or a set filtered by a polygon Help qualifying the RF parameter distribution Output: Provides statistical summary for key RF parameters

16 Reports Go/No-Go Used for: Go No-Go testing Comparing the KPIs against the SLA thresholds Multiple set of thresholds may be defined Two kinds of KPIs Application SLA KPIs (accessibility, retainability, handover success, etc.) RF performance SLA KPIs (Rx Power, EcIo, Tx Power, etc.) Output: Report indication which KPI did not meet the SLA criteria.

17 Reports Site Verification Used for: Used for new site integration The KPIs are evaluated and compared against the thresholds Two kinds of KPIs Application SLA KPIs (accessibility, retainability, handover success, etc.) RF performance SLA KPIs (Rx Power, EcIo, Tx Power, etc.) Output: Single Site Verification Report checking RF performance and Application performance for each sector.
