Activities/Duties
 Responsible for Radio Network Optimization of 3G WCDMA HSPA+ and 2G network and
ensure that all the Radio Network KPIs based on RAN Stats and Drive Test analysis are
constantly met as predefined by the client.
 Automatic Frequency Planning (AFP) implementation to reduce Interference and drops.
 Analyze high congestion cells with respect to UL/DL Power, Code, UL/DL CEs and UL/DL IUB,
provide solutions and propose expansion where possible
 Analyze and diagnoses of high RTWP cells, and troubleshoot external/internal interference by
scanning frequency in LMT Node B. Propose solution if RTWP is caused by genuine traffic
 Issues diagnose like PS/CS abnormal call releases, HSDPA/HSUPA Low throughput and
RRC/RAB establishments through OSS stats, NASTAR Cell level Analysis, call history records.

taking necessary actions on it.
 Mapping drive 3G/2G drive test data with perditions and propose physical optimization changes
to improve coverage and quality.
 Optimization and weekly monitoring of worst performing cells through weekly reports on the
basis of Network Key Performance Indicator(KPI).Major KPIs including TCH Drop Rate, CSSR,
HOSR, SDCCH/TCH Blocking rate etc. to improve network quality
 2G & 3G Feature review and implementation to improve network performance
 Traffic forecast analysis, to make recommendation for proper network capacity planning and
optimization.
 Perform series of meetings with client “Network Providers” to implement features that will
improve network performance and maintain stability.
 Defining neighbor strategy between different technologies.
