Mobile Subscriptions and Penetration
3
Impact of Mobile Growth
Increased demand for numbering resources
Demand on investment: network capacity
Potential negative impact on QoS/QoE
4
Efficient Number Utilization
Growth of mobile subscriptions Numbering resource demandNumber block allocation
Regulatory interventions for efficient number allocation:
Charging for numbersNumber portability
5
Number Portability Drivers
Consumer demand:Location/service neutralityLimit disruption/expense of number change
Regulatory tool:Efficient utilization of numbering resourcesPromote competition in a multi-operator environmentEnhance consumer freedom of choice

Number Portability and QoS
PARAMETERS TARGETSCompleted Calls >90%Call Set Up Time <13.5 seconds
Call Drop Rate <2%Call Block Rate <10%Speech Quality MOS for 95% of
samples > 2.7Others
Customer Service Response time
% of complaints resolved with a pre-determined time period Service coverage
7
Number Portability and QoS
Customer satisfaction: QoS expectations ≠ Perceived QoSOperation flexibility = Number portability Number portability = Customers flexibility Customer flexibility = Customer satisfaction

Number Portability and QoS
Number portability rewards competitive operators with:
Lower TariffHigher QoS/QoEWider service coverageWider-range of innovative services Consumer-friendly service

Number Portability: Application in Kenya
1st Public consultation; 2004Responses:
1 fixed operator - no favourable porting operator2 Mobile operators – unnecessary customer churnConsumer concerns – lack of tariff transparency of on-net and off-net
10
Number Portability: Application in Kenya
Decision to defer until:The market had at least 3 mobile operators Differential between on-net and off-net tariffs narrowed
Market place changes:4 mobile operatorsUnified Licensing FrameworkNew interconnection framework

Challenges
Network externalities:Increase in number of users increase value of network to other users: Dominance?
Fisheries problem:Each user decreases the value of the network participation for all the others- lower Qos
Consumer lock-in Strategies:Value added services
Large pre-paid subscriber base:Low income and low usage Cheap SIM

Opportunities
Consumer choice
Competition
Better QoS
