| Description: |
• To identify coverage gaps and traffic congestions for new sites integration and expansions.
• Survey to identify potential site locations to improve the coverage, quality and capacity.
• Site design and dimensioning Antenna type, Azimuth and Tilt, Traffic analysis, TRx required per sector.
• 3G, 2G, 3G/2G neighbor planning for new site integration and neighbor list optimisation for existing site (using Netact).
• Identifying interference issues ( 3G-EC/I0, 2G-BCCH clashes, BLER, SDCCH failures) and taking necessary steps to resolve them ( i.e. tilt, repan of site, change of scrambling code, frequency retune, parameter tuning)
• Responsible for testing and improving the 2G radio performance for the newly integrated 3G sites, where the performance degradation was noted in 2G radio after the 3G upgrade.
• Cell by cell health check and optimisation through OSS statistics .
• Monitoring of cell level statistics extracted from Metrica (MS Access) such as CSTR, DCR (UL/DL Quality and signal strength issues), and subscriber perceived TCH congestion, SD congestion, excessive timing advance, link imbalance etc.
• Classification of clusters and definition of drive routes, ensuring the route covers all test sites plus area of ISHO.
• Drive test analysis (2G/3G) for overall Call Drops, Call Setup Failures, ISHO and Missing Neighbors, administration of antenna and azimuth changes to ensure dominant pilot, RSCP coverage, reduction of interference, pilot pollution, overshooting cells and active set size using Layer 3 messaging (X-cal,X-cap, TEMS).
• 3G KPI Analysis (RRC Access, setup, Active Failures, RAB drops and Failures (conversational, streaming, interactive and background classes) using Metrica.
• Evaluate and adapt new methods and technologies regarding Radio Network Optimisation & tuning.
• Co-ordination with other departments of O2 to resolve performance issues
