TEMS™ VISUALIZATION 7.3 ENTERPRISE
Exception analysis
summarizes all of the GPEH messages recorded for
the selected scope and all of the TEMS Visualization events generated. For
selected GPEH messages, users can drill down even further and count the
occurrences of different RAB types and cause values. There is no more ef-
fective way to find the root causes of network problems. Calls containing
the selected events can then be sent to call analysis.
Call analysis
allows drill-down to the individual call level. Calls high-
lighted in any feature can be sent to call analysis for in-depth examination.
Sequences of signaling messages are shown, and the reasons behind prob-
lems such as blocked and dropped calls can be investigated in great detail.
Users can follow radio measurements per call, view detailed content for
individual messages, retrieve distance and quality information, and analyze
large groups of calls for patterns. This extremely powerful feature can, for
example, quickly determine if all dropped calls in a cell are generated by the
same user or on the same RAB type.
WCDMA capacity diagnostics
identify cells with resource issues by
using peak usage statistics for key resource types. Problem cells can then
be examined in detail with charts showing the usage of resources such as
channel elements, power, and active high-speed users in high-resolution.
WCDMA RF diagnostics
automatically highlight cells with RF issues.
Analysis of measurement reports identifies cells with problems 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 miss-
ing IRAT/IFHO handovers, UL path losses, overshooting cells, or pilot pollu-
tion. The MRR-W feature in the Ericsson OSS-RC is required.
WCDMA geo-location of selected events
enables dropped calls to be
geo-located, with the number of dropped calls in each 100m x 100m bin
displayed on the map. Clicking on a bin presents details for the drops in that
bin and allows further drill-down.
