Total years of experience :12 years, 4 Months
• Network KPI's monitoring and enhancement mainly (CSSR, CDR, TBF Est. Succ. and drop Rate, RRC SSR, RRC DR, RAB SSR, RAB Drop rate)
• Perform drive test analysis on weekly basis for VIR (Very Important Roads) and clusters per RNC and on monthly basis for benchmarking with competitors using TEMS investigation 11 to identify/solve radio performance issues like poor coverage; bad quality; pilot pollution;
• Monitor & analyze CS/PS Radio Network Statistics on daily basis using M2000
• Respond to weekly and monthly worst cells reports
• Applying second carrier strategy
• Minimize RNC DCR and Blocking rate by idle mode; handover and admission parameters' tuning in addition to CS/PS traffic balancing between first and second carriers or between 3G and 2G cells using load sharing methods
• Perform physical parameters tuning to reach optimum coverage for each cell by changing antenna mechanical/electrical tilts and height to solve bad coverage spots and pilot pollution and adapt the integration of a new sites
• Monitor cell traffic and issue the expansions needed to absorb the traffic growth
• Optimize Hand over parameters to achieve best mobility performance
• Optimize HSPA/HSPA+ parameters to ensure the best data
• Perform trials for 2G and 3G new features to reach the optimum setting according to the network profile
• Monitor network performance during special events (concerts, demonstrations and Eid vacations; ... etc) and perform aggressive parameters' tuning and physical actions to absorb the huge traffic increase in addition to COW deployment if needed
• Requesting new sites for poor coverage spots with the support of planning team.
• Neighbor and parameter audit.
• Hardware problems and alarms escalation.
• Data Services Optimization: Remote Network Analysis, Planning, Tuning, Optimization & Capability Management for Data services.
• Accessibility (GPRS Attach Success Rate, PDP Context Activation Success Rate), Data Retention (TBF Success Rate/Drops).
• Maintaining/optimizing target PS Core network KPIs.
• Analyze & troubleshoot any KPI degradation/providing solution for its fixture.
• Preparation of usage stats and analytical reports.
• Queries and complaints handling of PS Core related issues from other business/customer units.
• Traffic analysis in order to identify KPI deviation and capacity issues.
• Keeping track of PS Core service degradation and outages.
• Analysis of TEMS Investigation log files
• Post processing Drive test and core network data troubleshooting/ benchmarking.
• 2G KPI monitoring (CSSR, SD/TCH Drop Rate, SD/TCH Blocking, CSR, DL/UL Quality, etc.
• Optimization through study of BSS Parameters, Antenna swapping, changes in antenna orientations, tilt etc.
• Optimization base on daily performance and identifying cells contributing to poor KPIs such as call RRC failure, CSSR, drop rate, handover failure rate, SDCCH & TCH congestion, SDCCH drop etc.
• Initial analysis and isolation of degraded BTS performance.
• Parameter Audit neighbor relations configuration of newly integrated BTS.
• Frequency interference analysis, adjacent and co-channel.
• 2G worst cell analysis and recommendations.
• Complaints handling related to quality, dropped calls, coverage issues, etc.
