Current situation on how to control QoS?How to effectively control the QoS?Drive Test and / or Monitoring 24hours/24?

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?

6

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

Current state about measurement of QoS

However, they have an interest, that of measuring such coverageThey reflect a snapshot of the state networks

Cotonou, Benin, 16-17 July 2012

They are tools greatly appreciated by the regulators and operators

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.

Cotonou, Benin, 16-17 July 2012

A new and Complementary Approach

Cotonou, Benin, 16-17 July 2012

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 approachHardly used by regulators, as long implementation for reasons primarily regulatoryThey 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

Cotonou, Benin, 16-17 July 2012

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 SOLUTIONRPM SYSTEM SOLUTION

16

QoS control systemSystem 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

17

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

QoS control system

18

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
