Context
 Very strong growth of the market for mobile telephony observed
these recent years (7.5 % of penetration in 2003, 38.9 % in 2007 and
more 106% in December 2014);
 More stringent requirements of consumers with the generation of Multimedia
services and the uses of the mobile;
 Downgrading Quality of Services during the promotional sales;
 Less satisfactory expectations of consumers and resurgence of complaints in
matters such as availability of service, coverage, throughput, .. ;
 Instructions from the Managing Director to raise the QoS to one of
the Priorities of ARTP notably the QoS perceived by the Consumer;
 Orientation toward the QoE;
 Ambition to align on the International Standards;

Objectives targeted through the Plan of
Actions
 Ensure compliance with the provisions of specifications for operators and
decisions of ARTP in the field of QoS;
 Enable consumers to access to emergency services at any area in the territory ;
 More stringent requirements of consumers with the generalization of multimedia
services and the uses of the Mobile;
 Bring the operators to continuously improving the QoS of their networks and
create a dynamic of competition through the QoE ;
 Improve the coverage of the territory in population and area;
 Equip ARTP with equipment and adequate platforms, for control of vocal
services QoS/QoE, SMS and data;

Elements that have guided the choice of
The Plan of Actions
 The improvement of the QoS/QoE retained as the top Priority in 2015 by
the Executive Department of ARTP ;
 The follow up of the QoS such as what is perceived by the user on a
daily basis ;
 The taking into account of the Consumer’s concerns ;
 The taking account of the strategic plan of ARTP 2015-2017
 Obligation for ARTP to give visibility to operators , consumers and other
actors, on its system of caring for the mobile QoS/QoE in 2015.

The Components of the Plan of Actions 1/2
 The strengthening of the control and monitoring platform of the QoS of
the networks of mobile telephony operators;
 The Establishment of a system for handling consumer
complaints and Information for the general public on the QoS/QoE of
operators’Networks ;
 Supervision of the QoS of the operators’networks of mobile telephony
during religious events (Touba, Tivavouane, Kaolack, Popenguine,
Call Limamoulaye, ETC. ) and the venues of mass meetings;
 Acquisition of Equipment for the measurement of the QoS/QoE ;
 Operation of an attending and monitoring device of calls towards
emergency numbers ;
9
31.05.16
The Components of the Plan of Action 2/2
 Acquisition of a Platform for the assessment of the quality of service (QoS)
and the quality of experience (QoE) of Networks of mobile telephony;
 Technology Watch on the monitoring of the QoS/QoE of mobile telephony
networks;
 Dynamic Monitoring of the Development of infrastructure of mobile
telephony operators (coverage maps);

Description of the different components of the
plan of actions
11
31.05.16
1. Strengthening of the control and monitoring platform
of the QoS of Mobile telephony operators 1/2
 Revision of the threshold of QoS indicators (KPI) in accordance with the
best international practices and in consultation with the operators ;
 Bilateral meetings each quarter with the QoS operators to draw up statements
of the previous quarter and set the prospects for the next quarter. At the end of
these meetings, a communiqué will be released for all the sector actors;
 Realization of quarterly measurement campaigns by area in accordance with
the administrative divisions of Senegal to raise defaults and have them addressed
by operators ;
12
31.05.16
1. Strengthening of the device control and monitoring of
the QoS Mobile telephone operators 1/2
 Realization of a campaign of measures for the coverage of the operators
networks on the national territory (field measures) with restitution
meetings for all the actors of the sector and publication of results
during the first semester of 2015 ;
 Establishment of a new watch device on the QoE in the 45 departments of
Senegal from the first semester of 2015, by selecting the bêtatestors
that are able to trace back malfunctioning in real time observed on
the networks of operators.
13
31.05.16
2. Establishment of a system for handling consumer
complaints and information of the general public on
the QoS/QoE :
 Ad hoc operation of QoS measures further to complaints of consumers;
 Publication of a decision pertaining to the upgrading of the procedures
of consumers’complaints handling on the QoS (Consumer associations
will be strongly consulted) ;
 Establishment of a tool to allow consumers to report their claims up to
ARTP in real time;
 Communication on the management of the QoS and the use of phone
devices on missions.
14
31.05.16
3. Supervision of the Mobile QoS during religious events an
in venues of mass meetings:
 The relevant religious events are: Magal, Gamou of Tivavouane, of Kaolack
and Medina Gounass, Popenguine, Daaka, ETC
 For each event, the following device is provided for:
• Establishment of a toll free number;
• Presence of a team of ARTP on site throughout the length of the
event (the realization of measures, coordination with the
operators, the organizers, etc. ) ;
• Communication around the event (Press, radio, Web,etc. ).
15
31.05.16

the QoS Services:
 Acquisition of tracing Mobile for the realization of ad hoc measures of the QoS ,
in case of complaints from consumers;
 Acquisition of two (2) spectrum analyzers, allowing to carry out measurements of
the quality and the speed of ADSL lines for customers ;
 Acquisition of a QoS measurement chain allowing to:
• Perform measurements of the Quality of vocal services and data of
mobile communications (QoS) ;
• Appraise the level of actual coverage of each of the operators of
mobile telephony on the basis of the coverage maps provided by those
operators ;

the Quality of Service (QoS) and the Quality of Experience
(QoE) of uses of Mobile telephony networks
 Establishment
of
a
platform
capable
of
collecting,
treating and
analyzing the performance
indicators of Mobile telephony networks, regardless of the technology
and services offered;
 A Solution Capable to oversee the Quality of Service and the Quality
of Experience provided to users.
