QoS VS Regulators
Current situation on how to control
QoS?
How to effectively control the QoS?
Drive Test and / or Monitoring
24hours/24?
Cotonou, Benin, 16-17 July 2012
Objectives of Quality of Service
for regulators regarding to Users
What are the Expectations of a User for QoS in mobile networks ?
Network availability (probability of obtaining a new call),
Maintaining communications,
Voice quality of communication
One of the main roles for the regulator is :
Ensure compliance with the application of the specifications provided to
operators in the awarding of the license,
To assist operators in their efforts to improve the QoS to satisfy the final
consumer
The key points to control the QoS of the networks?
5
What are The key points to control the QoS of the
networks?
Regularly monitor and enforce the specifications
strictly
Ensure a good network coverage and a good voice
quality
Ensure competition between operators for lowering
call prices
Communicating the results of the network status
to end_users
…

Current state about measurement of QoS
Drive test and/or END TO END
measurement are mainly outdoors and periodic:
o some parts of the territory or buildings, highways
and main roads
o a given period : once a year for over a month
7
Current state about measurement of QoS
However, they have an interest, that of
measuring such coverage
They reflect a snapshot of the state
networks
They are tools greatly appreciated by the
regulators and operators
Cotonou, Benin, 16-17 July 2012
Others current state/QoS measurement
Customer complaints:
This is an important source of service quality that
cannot be ignored.
The protocol analyzers:
They are connected to the BTS, BSC and MSC over
time to check for problems on the mobile network.

A new and Complementary Approach
In 2005, PNI designed a complementary tool
which provide KPI’s Reports 24 hours a day.
Reports take into account OMC/R RAW DATA
Cotonou, Benin, 16-17 July 2012
OMC/R Raw DATA approach
Hardly used by regulators, as long
implementation for reasons primarily regulatory
They are obtained by collecting raw data from
the OMC/R among operators.
To be usable, they are transformed into KPI
(Key Performance Indicators).
KPIs are obtained using formulas and the
compilation of various data.
KPIs are used to assess the maintenance of the
call, the volume of traffic, quality of service
across the network.
KPIs can thus detect cells at fault, the peak

hours.
Some KPI’s commonly used
Failure rate of HO Handover Request or DL /
UL Quality Rate: commonly used threshold
<2%
Call Setup Success Rate (CSSR):> 95%
Call Drop Rate (CDR): commonly used
threshold <2%
Levels of congestion or TCH Blocking Rate:
commonly used threshold <2%
Cotonou, Benin, 16-17 July 2012
OMC/R Raw DATA approach
KPI'S from OMC/ R are key elements:
Indisputable, as from raw data permanent
and traceable over time ....
To be usable, they are transformed into KPI
(Key Performance Indicators).

RPM SYSTEM OVERVIEW

The solution put forth by PNI
RPM SYSTEM SOLUTION
15
QoS control system
System that records each call from each
subscriber 24h/24 no matter its location in a
given network
System at the forefront of Web technology
Powerful database system
Multi-vendors (compatible with all vendor
equipment of operators around the world)
Multi-technology : 2G, 3G, 4G …
Completely designed to meet the needs of
regulators
16
QoS control system
This system provides the following services and
more to regulators:
Functions of analysis, edition reports and alarms
Historic of data by operator
Supervision and monitoring monthly for the issuance of
penalties against the operator which does not respect the
specifications
Better quality of service ensured for the end users
17
QoS control system
Features of this system:
Collecting Raw data counters OMC-R of any
equipment
Technology based on Web browsing 2.0
Automatic alerts of events by email
System allowing to send reports automatically by
email
Alarm programming
Unequivocal data processing
Easy-to-use
