TEMS™ VISUALIZATION
BRIDGING THE OPTIMIZATION GAP
2 TEMS™ VISUALIZATION 7.1 PROFESSIONAL
SEE YOUR NETWORK IN A WHOLE NEW WAY
TEMS Visualization Professional is
revolutionizing the way network
operators troubleshoot their
networks, enabling them to find
problems that were impossible to
pinpoint before.
TEMS Visualization Professional
provides this ability by analyzing
event-based data generated by the
infrastructure.
The optimization gap
TEMS Visualization Professional processes event-based data, analyzing
and organizing it so that it can be used for network optimization. Operators
have easy access to comprehensive information based on measurement
results and call events, all the way down to the individual call level. This
information can be used for troubleshooting, monitoring, and verifying net-
work functionality.
This ability to look at real individual call data from the infrastructure
side bridges the gap between ordinary Performance Management systems
and traditional drive testing. While Performance Management tools provide
powerful statistical and trending functionality, and drive test tools capture
a specific slice of the network in great detail, TEMS Visualization Professional
gives a closer look at every call from every mobile in the network.
TEMS Visualization Professional is designed to be installed and run on
a single machine. The TEMS Visualization Enterprise solution is also available.
This utilizes dedicated servers for the data processing with many clients
able to connect to the centralized data storage.
Benefits
▪ Trap, track, and eradicate problems based on sequences and specific phone
models.
▪ Understand network problems by viewing the full details of calls made in
the network – all calls, all phones.
▪ Drill down into subscriber issues easily using powerful filtering capabilities
and fast browsing functions.
Key features
▪ Processing of event-based data from both WCDMA and GSM networks
▪ Display of full details for all calls on networks with Ericsson infrastructure
▪ Easy optimization of today’s very complex networks with built-in
optimization functionality
▪ Direct import of network configuration data from OSS-RC through CNAI
and BulkCM
▪ IRAT Call Tracing using UETR and MTR
▪ Automated task management

Call Event Analyzer
The Call Event Analyzer makes every call within the recorded cell set
available for detailed analysis. It allows the operator to see the major events
associated with a particular call in a history view. Using powerful filtering
and sorting functions, it displays the flow of handovers as either an event
list or plotted on a map. Calls with abnormal events (dropped, blocked,
handover failure, etc.) are easily identified.
TEMS Visualization Professional works with data gat hered by the
Ericsson OSS-RC. Supported formats are GPEH and UETR for WCDMA net-
works , and R-PMO, MTR, and CTR for GSM. TEMS Visualization Professional
is compatible with the newest enh ancements a dded on the event side
for both technologies. TEMS Visualizatio n Professional follows calls over
BSC borders, allowing the user to anal yze Intra-BSC handovers and follow
all calls mad e in the recording area. It is now also possib le to trace calls
between WCDMA and GSM.
By using TEMS Visualization, operators can do the following, and much
more:
▪ Optimize daily worst cells.
▪ Validate channel allocation (e.g. AMR, overlaid/underlaid optimization).
▪ Filter out calls originating from a selected cell and follow the movement
of each call.
▪ Find the location of dropped calls by following the progression of
serving cells.
▪ Optimize WCDMA neighbor plans.
▪ Identify problems where only one link suffered from poor quality
(uplink and downlink measurement data are available in the tool).
▪ Determine poorly performing mobiles or mobile types.
▪ Analyze problems dependent on response time using the time
difference histogram feature.
In addition, it is easy for the operator to follow the events, radio
environment, and graphical presentation of the serving cell for every call.
This helps operators identify the real reasons for dropped calls, understand
traffic patterns, find missing neighbors, identify ping-pong handover areas,
and perform a host of other optimization activities.
For WCDMA, it is also possible to keep track of the signaling between
the mobile and the core network. Selected information elements are de-
coded such as the cause value for any location or routing area update reject.
