Objectives of quality of service for regulators Definition: Quality of Service can be briefly defined

as the measurement of two main indicators :

Key Quality Indicators (KQIs) Key Performance indicators (KPIs)

The main role of the regulator amongst others, is:

To monitor Quality of Service (QoS) of mobile phone operators so that they comply and meet the specifications they have been assigned in the issuance of operating license, and To assist operators, as well as challenging them, in improving the quality of services offered to end-users(subscribers).

Several methods for evaluating the QoS of operators

5

Objectives of quality of service for regulators 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 endusers … 6

Current state about measurement of QoS Drive test and/or END TO END measurement are very limited and subjective in that it is mainly outdoors and periodic: o some parts of the territory : buildings, highways and main roads o a given period : once a year for over a month Need for expensive tools that needs to be constantly updated: new technology, new mobile testing… Results are disputed, owing to ineffective control over time 7

How to control QoS ?

1

Means/Process A specific audit = current network status Voice quality measurement (user’s perception) Measurement of Key Performance Indicators (KPIs) and Key Quality indicators(KQIs) 2 Establishing a system of QoS management Unequivocal Permanent Penalties

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 10

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 11

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 12
