Visualization enhancements

By NEIL STOBIE and ERIC ALLSTROM

TEMS Visualization 6.0 introduces a

number of features that extend the

tool’s functionality and usability. These

include support for new system releases,

a new database, and substantial en-

hancements to the GSM Module.

New system releases supported:

CTR, and CNAI export

New database

Perhaps the most signiﬁcant enhance-

ment in this release is the addition of

Microsoft® SQL Server 2008 Standard

as the main data store. This compre-

hensive new data warehouse platform

offers the advantage of virtually unlim-

ited database size. It enables users

to analyze more data over longer time

periods, and as a result they have more

conﬁdence in their decision making.

New for GSM

The GSM Module now contains a

binned map feature. When estimated

positions of measurement results have

been calculated, one or more databases

can be loaded into TEMS Visualization

6.0 to create binned maps. These do

not represent predictions but show the

actual conditions as experienced by

the live trafﬁc in the network.

Binned maps can be created for:

A typical use case would be ﬁnding

an area of poor signal strength and

then using the trafﬁc density maps

to determine if investment in a new

site would be justiﬁed. The maps

can either be displayed directly in

TEMS Visualization (MapInfo format)

or exported to Google

™

Earth (kml

format).

The GSM Module also offers two

important new reports:

oƞ GSM Find Faulty Antenna eXpert

Report – shows the measurements

made on the receive branches,

through the FFAX feature in the OSS-

RC, of signal strength differences

(RxLev A – RxLev B) on both cell

and RX levels. The report also shows

if these differences increase with

timing advances. This helps detect

vertical misalignment when different

antennas are used for the receive

branches.

oƞ GSM Speech Quality Report –

shows distribution graphs of the up-

link speech quality as experienced by

subscribers. It also estimates what

the speech quality would have been

if the AMR codec set had not been

available.

The GSM Tracing Module now sup-

ports the Cell Trafﬁc Recording (CTR)

format from the OSS-RC. Event data

for calls passing through a speciﬁc

cell can be captured in a CTR ﬁle, and

the ﬁle can then be analyzed in TEMS

Visualization. This makes it possible to

investigate the performance of a single

cell in great detail.

Overall, the new features in TEMS

Visualization 6.0 enhance its ability to

use call-event data to detect network

problems that other solutions do not.



TEMS Visualization gives operators easy access to

comprehensive event-based data, all the way down to the

individual call level. This unique product bridges the gap

between performance management tools and traditional

drive-test data, providing RF engineers with an easier way to

troubleshoot network problems in both GSM and WCDMA

networks.
