Introduction

PURA is mandated by Section 13 of the PURA Act 2001 and Section 83 of the IC Act 2009

to monitor and measure the quality of service of licensed GSM operators and apply

sanctions where the Licensees fail to meet set targets or to provide adequate information

relating to Quality of Service.

This report is produced and published by PURA in accordance with the Authority’s

mandate, pursuant to Section 83 (d) of the IC Act and Section 10 of the Quality of Service

Guidelines for Mobile Network Operators (MNOs) in The Gambia.

The objective of the report is to benchmark, evaluate and publish quality Levels offered by

Mobile Network Operators, based on identified Key Performance Indicators (KPIs). The

Mobile Network Operators covered by the report include all four licensed MNOs.

Currently, there are two types of mobile network services offered by the operators, 2G and

3G, as shown below:

Operator Networks

AFRICELL 2G, 3G

COMIUM 2G

GAMCEL 2G-A,⃰ 2G-H*, 3G

QCELL 2G, 3G Table 1 – Mobile Network Operators

Gamcel 2G-A is the old Alcatel Network

Gamcel 2G-H is the newer Huawei 2G Network.

As new technologies are rolled out in the future, the reports will be adjusted accordingly.

The assessments are conducted using state of the art, modern technology, to obtain data

from the MNO’s systems directly. Human interference is minimal to zero.

Compliance rate of 9/12 KPIs. The network failed on only the PS Call Drop Rate, CS321InterRatHoSR and

PS321InterRatHoSR, same as in the previous month. 733 Cells deployed at end of August 2017 No cells reported downtimes during the month.

GAMCEL – 3G

Compliance rate of 4/12 KPIs. The network failed on all but the CS Data CSSR, CS Voice CDR, PS Call Drop

Rate and Soft HO Success Rate. 135 Cells deployed at end of August 2017 No cells reported downtimes during the month.

It is worth noting that GAMCELL has the smallest deployment of 3G sites and they only

operate in the Greater Banjul Area (GBA) and in Kanilai.

In addition, GAMCELL had billing platform issues and their entire network was open

for free on-net calling and Internet access, free of charge since users could not

recharge their accounts.

The main desired impact of the QoS Monitoring System is the improvement of services by

MNOs, and this includes the addition of new and/or improved Cell Sites to better serve the

consumers, and increase geographic coverage.

At the end of August 2017, compared to December 31st 2016, the number of Cells

deployed by each operator on each network is shown below.

10. RECOMMENDATIONS

1.1. Contents from this technical report will be used and put in an appropriate

format for publication.

1.2. As agreed with all Mobile Network Operators, they should ensure that faults

are reported to the Authority, by email, in line with the fault reporting

Guidelines. Planned maintenance or other offline periods should be

reported prior to the event(s).

1.3. All new Cells should be reported to the Authority in writing, prior to putting

them in service, as indicated in the QoS Guidelines.

1.4. Requests for QoS information or updates should be fulfilled as a matter of

priority, on or before the stated deadline in the request.

1.5. Data / information shall be provided to the Authority promptly and

consistently in prescribed standards. Deviation from the standards may be

considered non-compliance.

1.6. NO changes shall be made on the approved counters for the LPI Data

without the express consent of the Authority. Such requests for approval

must be in writing or by email. Non-compliance in this issue shall be

considered serious a breach and will attract immediate regulatory action.

1.7. With effect from August 2017, the monthly comparative performance

reports, along with other pertinent analyses and reports may be published

on the PURA website as deemed necessary by the Authority.
