HOW DOES AN OPERATOR KEEP CUSTOMERS SATISFIED?
In the competitive Mobile Internet environment, delivered Quality of Service
(QoS) is the key. In fact, good QoS can make the difference between a satisfied
subscriber and a former subscriber. Operators must take control of network
quality. To best manage this, the operator must receive continuous feedback
on the live network’s QoS, see the impact of optimization efforts on a regular
basis, and have an accurate means of measuring quality as perceived by
subscribers.
(QoS) is the key. In fact, good QoS can make the difference between a satisfied

on the live network’s QoS, see the impact of optimization efforts on a regular
basis, and have an accurate means of measuring quality as perceived by
subscribers.
In an effort to fulfill these requirements, operators have various
traditional channels for gathering information. One channel is the collection
of “fixed side” data, from the Operations Support System/Network
Management System (OSS/NMS). This data is necessary but is generally
used only for statistical analysis; without detailed processing, OSS data is
limited when it comes to QoS evaluation and the end-user’s experience.

limited when it comes to QoS evaluation and the end-user’s experience.
Another source of network information comes from the operator’s own
Customer Care department. While this is certainly a valuable source of data
about network problems, it, too, is limited. Very few subscribers will call a
Customer Care center when they are having problems. The rest may not
complain, but they will be more likely to switch to a competitor. In addition,
these disgruntled subscribers can be a very negative source of word-of-
mouth information regarding your network.

mouth information regarding your network.
Yet another way that network operators have traditionally obtained net-
work data is through manual drive tests. Drive testing provides a wealth of
valuable information, but is limited by time and resources. Drive tests are
usually performed on a set schedule, during regular working hours. They
are not always performed when the need is greatest, at times like rush hours
and weekends. In addition, manual test tools do not conduct end-to-end
(E2E) measurements. Although they are perfectly suited for troubleshoot-
ing and optimization, manual tests do not collect enough to deliver statis-
tically reliable data.

TEMS Automatic, however, exceeds the limitations of any other method.
It is an autonomous system that uses test probes to collect network infor-
mation which is transferred back to a central server for analysis and report
generation. An end-to-end solution, it employs handsets making calls over
the air interface, so that it can test from a subscriber’s perspective auto-
matically.

By working over the entire network area, 24 hours a day, seven days a
week, it gives statistically reliable data as well as QoS information. It tests
your network and your competitors, giving fair and accurate comparisons.
