En résumé

Summary of Skills and Experience:
Detail experience in RF Optimization & Drive Testing of GSM, GPRS, UMTS and EDGE. I had strong hands on RF Drive Testing experience with GSM (SIEMENS, HUAWEI, ERICSSON, and NSN) as a RF Engineer. Having experience with Huawei, Siemens, NSN and Ericsson BTS installation and commissioning. My main job responsibilities include RF Drive Test, Analysis and Optimization. For RAN optimization, I have strong experience of cells parameters fine tuning and physical optimization based on DT analysis. Radio capacity and transmission dimensionning is also included in my daily task.

  • Nokia Siemens Networks - Network Planning and Optimization Engineer

    ST OUEN 2011 - maintenant My main task is taking care of all network KPI by resolving all issues related to RAN. Parameters fine tuning, DT analysis, physical changes, capacity planning as detailed below.

    •Generation of KPI’s from OSS, BO and Logs from MML using Tang and Winfoil.
    •Optimizing the Radio network to ensure the benefits like operational excellence, optimal use of resources, improvement of network KPIs, support to TSG for better FTR closures, storage of all DT plots in a server for further analysis & records for benchmarking, and customer satisfaction etc.
    •Monitoring Key Performance Identification (KPI) by means of SDCCH/TCH drop calls, call set up success rate, handover success rate and congestion rate, and conducting Final acceptance test Report by means of statistics and drive test measurements.
    •Analyzing and troubleshooting the worst performing cells based on high drop call rate, poor Hanover success rate, low CSSR, poor uplink and downlink Quality in Network/BSC to improve the overall signed KPIs.
    •Optimizing data timeslot utilization by fine tuning CDED/CDEF parameters based on the guideline and data traffic trend.
    •Analysis the current status of cells using various MML commands on Tang.
    •Performed a neighbor list audit utilizing the handoff matrix, identified handoff failures and low handoff usage between different sectors in the network.
    •Leading GEMINI integration and sites rehoming activities based on BSC location, including implementation timeline, parameters audit, pre/post drive and KPIs monitoring.
    •Performed periodical Radio Network Capacity dimensioning (grow/degrow, reshuffling) based on traffic growth (both PS and CS).
    •Responsibilities for BSC reorganization plan based on BSC capacity and locality, LAC/RAC dimensioning accordingly.
    •Perform DT (benchmark and troubleshooting) using TEMS and NEMO. Log file analysis and post processing. Generate reports and recommendations using MapInfo tools.
