-Monitoring Identifies and solve proactively demanding problem on daily basis for WCDMA-3G/HSPA+/GSM/CDMA/EV-DO/GPRS/EDGE.
-Ensuring and keeping the performance of the radio network at the highest possible level by ensuring that degradations are handled swiftly & that the contracted KPI's are fulfilled for(Accessibility, Retainaibility, Mobility & Service Integrity)
-Develop process and working methods for 3G daily tasks Performance Management and Optimization process.
-Responsible for reducing Call congestion & drops, improving the IRAT Handover, Inter-frequency Handover , Soft Handover, Location Update, Paging, Call Setup Success Rate, Radio Recourse Connection & Radio Access Bearer Establishment Success rate in area for all Voice, Video Packet and High Speed, issuing capacity requests whenever needed.
-Network parameters and KPI formula Inconsistencies Check on nodeB and RNC level.
-Coordinating another departments to sort performance issues in the network through proper coordination and analysis traces at different interfaces.
-Responsible for testing the radio performance for the newly integrated sites.
-Drive testing and log file analysis, making KPIs reports. Make report and Post Processing and analyzing call drops, call setup, failure and coverage.
-Perfoming Drive test using Genex Prob & TEMS Investigation( CS/PS,HSPA+ and Scanner ), analyzing & taking the necessary action to improve the performance of this area (Pilot Pollution, weak Coverage, Low Throughput and Quality etc.)
-Perform Radio Network Surveys, i.e. visit possible sites in order to judge if they are suitable from a radio network point of view (Hardware and Location).
-Evaluate and adapt new methods and technologies regarding Radio Network Optimization, Features, Trials and Tuning. Identify NodeB hardware problems and alarms and escalate to corresponding departments.
