TEMS™ VISUALIZATION ENTERPRISE

BRIDGING THE OPTIMIZATION GAP

2 TEMS™ VISUALIZATION 7.2 ENTERPRISE

SEE YOUR NETWORK IN A WHOLE NEW WAY

TEMS Visualization has revolutionized

the optimization of WCDMA and GSM

networks. It post-processes event-based

data generated by the Ericsson

infrastructure, analyzing and organizing

it for troubleshooting, monitoring, and

verifying network functionality.

Looking at individual call data from the infrastructure side bridges the

gap between performance management systems and drive testing. While

performance management tools provide masses of data, and drive-test

tools capture thin slices of network trafﬁc, TEMS Visualization derives de-

tailed information from large volumes of data.

This recently developed, Enterprise-grade solution gives RF engineers

the most effective way to troubleshoot and optimize WCDMA networks.

The General Performance Event Handling (GPEH) application available

in Ericsson networks enables the collection, retrieval, and storage of event

data for WCDMA, in greater volume and detail and more cost-effectively

than is possible using passive probes. Files are generated in the network

elements (RNC) and collected in the OSS-RC ﬁle storage for post-processing

by TEMS Visualization Enterprise.

Powerful – This is a true Client/Server solution, designed for 64-bit

Servers. Large volumes of data can be processed, stored centrally, and ac-

cessed remotely through the Client application.

Automated – Data processing can be completely automatic. Also, the

new Diagnostics features help users ﬁnd root causes for RF and capacity

problems quickly.

Better decisions –The large volumes of decoded event data and smaller

volumes of calculated statistical data are stored separately. This means

statistical data can be stored and analyzed over longer time periods – giving

operators more conﬁdence in their decisions.

HOW TEMS VISUALIZATION ENTERPRISE WORKS

3TEMS™ VISUALIZATION 7.2 ENTERPRISE

The product consists of a Server and Clients.

The Server collects, processes, and stores all data, and a powerful data

processing engine keeps pace with increasing data volumes. Enterprise has

been designed from the bottom up with 64-bit support and multi-core/CPU.

The Clients send queries to the Server, collect the results, and depict

them visually. Users install the Client software on their own machines with-

out added remote access software.

The separation of data into Primary and Analysis Databases allows

troubleshooting and optimization based on data collected over long time

periods.

After recordings have been set up in the OSS-RC, the data ﬂow through

the TEMS Visualization Enterprise system can be immediate and completely

automatic, with no need for manual processing or scheduling at any stage.

“TEMS™ Visualization Enterprise is a true Client/Server solution, providing processing, storage, and remote access for large volumes of data.”

POWERFUL, UNIQUE FEATURES

Intra-frequency Neighbor Optimization

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.

Coverage Area Optimization

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.

Detailed Investigations

Exception Analysis summarizes all GPEH messages recorded for the

selected scope and all the TEMS Visualization events generated. For se-

lected 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 can be analyzed 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.

Geo-location of selected events is based on measurements made by

the mobile and reported to the RNC. Areas where several cells are involved

in overlapping coverage are geo-located on the map, allowing engineers to

determine if:

 Cells are providing coverage in unwanted areas and causing Pilot

Pollution.

 Wanted cell coverage will still be good if, for example, the polluting cells

are down-tilted.

 The reason behind Pilot Pollution is simply poor coverage.

5TEMS™ VISUALIZATION 7.2 ENTERPRISE

In addition, dropped calls can 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.

GENERAL FEATURES

 TEMS Visualization Enterprise can take in the BulkCM format directly

from the Ericsson OSS-RC and store the required information in the

Project database. This includes neighbor cell relations and selection

priorities and other cell parameters that the features require.

 Any missing information, such as latitude, longitude and antenna

direction, and beam-width, can be taken from a reference ﬁle.

 The time duration of data to be analyzed can be selected independently

for each feature.

 TEMS Visualization includes the most widely used map engine in the

world, MapInfo’s MapExtreme®. This makes it possible to reuse all the

maps currently used in TEMS™ Investigation and MapInfo.

 The functionality in the map view includes thematic mapping display

from all of the advanced TEMS Visualization Enterprise features.

 TEMS Visualization Enterprise makes it easy to differentiate on the map

cells between different carriers (UARFCN) at the same site location.

Separate display ﬁlters are automatically created.

 Uses the Microsoft® SQL Server 2008 Enterprise database solution.

 Geo-locates selected events based on measurements made by the

mobile and reported to the RNC, with results presented in map graphics.

Enables engineers to pinpoint the causes of Pilot Pollution and dropped

calls.

 In WCDMA networks, accurate neighbor planning is crucial to perfor-

mance, especially with second and third carriers becoming common-

place. Neighbor Optimization features make it possible to quickly and

easily optimize neighbor plans based on real customer trafﬁc.

 An array of KPI views is presented, by cell, subscriber, and subscriber

group. HS data performance analysis includes average throughput

statistics in all views.

 User-deﬁned queries employ raw data with complex conditions.
