6 TEMS™ VISUALIZATION 7.3 ENTERPRISE
RF OPTIMIZATION – PROACTIVE KPI MAINTENANCE AND IMPROVEMENT
TEMS Visualization Enterprise also includes features that increase effi-
ciency in the most important day-to-day RF optimization tasks. Utilizing
the live subscriber traffic, engineers can make the most well informed
optimization decisions and positively impact subscriber perceived net-
work quality.
WCDMA neighbor optimization makes it possible to easily optimize
the neighbor plans, which are crucial for network performance. Missing
neighbors and non-utilized existing neighbors are identified for both intra-
frequency and, uniquely, inter-frequency relations. Per-IMSI statistics allow
the exclusion of individual subscriber specific issues – and the engineer to
focus on true network issues. All of this information is linked to the map
view for easy analysis. Changes can be made and saved to a Bulk CM format
file for import into the OSS-RC.
WCDMA coverage area optimization allows overshooting cells to be
quickly identified and down-tilts adjusted. An algorithm calculates an over-
shooting distance for each cell. During processing, statistics are calculated
for the number of overshooting calls and the number of calls established in
poor quality. Detailed investigation of the calls established in each distance
band and the quality of those calls can also be shown in charts and on the
map.
WCDMA geo-location of pilot pollution allows areas where several
cells are involved in overlapping coverage to be geo-located on the map,
enabling engineers to determine if:
ƒ Cells are providing coverage in unwanted areas and causing pilot
pollution
ƒ Wanted cell coverage will still be good if, for example, the polluting cells
are down-tilted
ƒ The reason behind pilot pollution is simply poor coverage
