TEMS™ VISUALIZATION 7.2 ENTERPRISE
Automated Network Diagnostics
Many causes of performance degradation are basic problems.
Congestion can push traffic to non-optimal cells, installation problems can
result in swapped feeders or overshooting cells, real-life coverage can differ
from predictions, and equipment can fail. Capacity Diagnostics and RF
Diagnostics highlight cells with these issues and search for the root causes.
Capacity Diagnostics
identify cells with resource issues, and peak us-
age statistics for key resource types are calculated. Problem cells can then
be examined in detail with high-resolution charts showing the usage of
resources such as channel elements, power, and active HS users.
RF Diagnostics
automatically highlight cells with RF issues. Analysis
of Measurement Reports identifies cells with issues such as out of coverage,
high DL interference, high UL interference, or UL/DL imbalance. Further
analysis identifies the potential causes of these issues, such as missing IRAT/
IFHO handovers, UL path losses, overshooting cells, or Pilot Pollution. The
MRR-W feature in the Ericsson OSS-RC is required.
Optimization Decision Support
Neighbor Optimization
makes it possible to easily verify the neighbor
plan (crucial for network performance) and find both missing neighbors and
non-utilized existing neighbors in a WCDMA network. Missing Neighbor
statistics, as reported by actual users, existing neighbor usage, and Pilot
Pollution statistics are presented. Per-IMSI statistics allow classification of
missing neighbors as UE or network issues. This information is linked to the
map view for easy analysis. Changes can be made and saved to a BulkCM
format file for import into the OSS-RC.
Coverage Area Optimization
allows overshooting cells to be quickly
identified and down-tilts adjusted. An algorithm calculates an overshooting
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.
