LTE Design and Optimization Engineer

Cluster level KPI monitoring and analysis through ENIQ related to Accessibility, Retainability, Integrity and Mobility. Troubleshooting of cells causing degradation in cluster level KPI.

Weekly worst cells analysis and troubleshooting based on different criteria including PDCP Throughput, Session Setup Success Rate, ERAB Drop Rate and Handover Success Rate.

Drive Test based Cluster Optimization to improve KPIs for coverage and quality. Addressing patches with bad SINR for improvement of subscriber perceived throughput via containment of cells and filling in coverage holes with dominant server creation.

End to end CSFB performance monitoring using MSS level CSFB stats (CSFB SGs End-User Perceived Paging Success Rate and Paging Procedure Success Rate). Highlighting Core parameter problems for rectification.

Optimization of CSFB Call Setup time and IRAT Session Continuity performance through tuning GERAN Cell relations and Redirect with System Information feature (RIM).

In depth analysis and troubleshooting of main events (Access failures, RRC drops, Handover failures) by analyzing Layer-3 messages from log files.

Extraction of parameter dumps through AMOS using Ericsson OSS and Nepa tool. Routine Parameters and Intra-LTE (A3 Handover) and Inter-RAT (A2 Handover) Neighbour Audits (and Optimization) to maintain the network performance.

Identify PCI conflicts, missing neighbor relations, overshooting cells and perform site verification and tilt recommendations to improve cluster performance.

Using Cell & UE Traces to investigate worst cells & for CSFB & Service Accessibility related issues reported by VIP customers.

Handling LTE customer complaints & making efforts to resolve them through physical design and/or soft parametric changes.

Evaluation of SSVs of LTE sites from design perspective as well as mobility & static testing of DL/UL Throughputs, latency, CSFB, Intra-LTE & IRAT Handovers & verification of radio parameters like PCIs, RSRP, RSRQ & CINR etc.

Identifying poor coverage/too many server areas and provide necessary tilts to improve the coverage and intra ping pong issues.

Identifying UL Noise issues caused by external Interference & escalating to the concerned departments.

Identifying Azimuth/Design discrepancies and Diversity Imbalance Alarms.

Technical checklist and parameter tweaking done to successfully pass all tests by Samsung & Apple in order to become their official partners to sell handsets through Warid Pakistan.

Warid Telecom, Pakistan November, 2011 - June, 2013

Radio Network Optimization Engineer

Trouble shooting and Optimization based on Statistical Analysis through ENIQ, Drive Tests & use of OSS tools like MRR, NCS, MTR, FAS etc. Identification of problems in 4 Major sections of 2G KPIs namely Accessibility, Integrity, Retainability and Mobility.

Trouble shooting worst cells with w.r.t. SDCCH/TCH Establishment, Congestion and Drop Rate; Using BSS parameters & software features like DHA, CLS, CHAP, SCLD, ACLC, Overlaid/Underlaid Subcell, Multi Band Cell, Power Control, Frequency Hopping, Frequency Re-use, HSN, MAIO, RLT etc. to optimize KPIs.

KPIs Optimization for both Indoor & Outdoor solutions; tuning of parameters using features like HCS (Hierarchical Cell Structures) for proper traffic distribution, handovers and to avoid IBS spillage.

Cluster/City vendor swaps experience including KPIs, parameter & drive test benchmarking analysis. Recommendations to improve these KPIs to maintain and further improve customer experience.

Special Events: Planning and generating Radio Plans for Special Events. Real-time monitoring of Statistics/KPIs through R-PMO.

Responsible for Optimization and Statistical Analysis of GPRS/EDGE KPIs such as Throughput, Radio Link Bitrates, TBF Establishment Rate, PDCH Allocation Rate etc at Cell/BSC level. DL EDGE Throughput & Accessibility analysis and improvement recommendations.

Design & optimize Paging per Second per BSC by improving Paging Success Rate by fine tuning LAC borders/CRH modification.

Lead the project and improved Paging Discards of highly congested BSCs by LAC splitting, MFRMS & AGBLK modification.

Generation & analysis of statistical data reports for identification of poor-performing cells in the network as per defined KPIs with the vendor.

Drive test data analysis in order to troubleshoot drop calls, call failures, handover failures, TCH/SDCCH congestion, bad quality, poor coverage, antenna tilt/orientation, add/remove neighbors, co/ad-channel interference and frequency retune.

Providing complete Cell Design Data (CDD), monitoring and verification of acceptance drive tests as per defined drive routes for newly integrated/upgraded sites of different phases in the regional network.

Analysis of frequency plans and neighbour relation discrepancies using Xeus.
