Drivers for Number PortabilityDeregulation and introduction of competition globally
Enhance Competition among Operators Create downward pressure on prices Introduction of new bundles of services Make it easier for newer entrants to gain market share
Consumers are moving towards a single number Enhances the concept of personal mobility like personal terminal
Mobile markets are driving the competition Mobile penetration rates are higher than fixed in most countries Mobile players are introducing new services faster Customers are replacing fixed phones with mobile phones

Types of Number PortabilityService Provider/ Operator Portability
The ability to retain the telephone number when switching from oneService Provider / Network Operator to another within a definedgeographic area
Fixed Number Portability (FNP): Geographic PSTN numbers Mobile Number Portability (MNP): Mobile telephone numbers Intelligent Number Portability (INP): Non-geographic IN numbers
Service Portability The ability to retain the telephone number when switching from one
telecom service to another (Fixed->Mobile)
Location (or Geographic) Portability The ability to retain the telephone number when moving from one
physical location to another Refers to porting of a geographic number from one location to
another

Number Portability.

NP Constituencies and Their RolesGovernment/Regulators
Laws; requirements; high-level implementation schedules Policies & regulations need to be clear, practical & enforceable
Operators and Service Providers Network and System upgrades; porting process; SOA/LSMS Operator and Service Provider readiness is essential
NP Clearinghouse Neutral, trusted party to facilitate and coordinate amongst competing operators Master routing database; porting management; porting data download; dispute
resolution, audit and reporting Experienced & proven CSMS provider is critical
Consumers End-users and main beneficiaries of MNP services Consumer awareness and public education is needed
Collaboration amongst all Constituencies = Success of MNP Deployment

Regulator ConcernsGeneral Views:
Removal of Competitive Barriers Conserving and optimizing numbering resources Consumer benefits
Key Concerns include: Ensure deployment of number portability
Provide impetus to create an Industry Consortium or workinggroup to agree to business rules
Ensure compliance with regulation Ports Completed within timeframe associated with regulation Reporting on compliance (e.g., are service providers meeting
their obligations?)

All Call Query
Pros Cons No involvement of Donor network Efficient call routing, uses Centralized DB Enables seamless use of services e.g. SMS, MMS, ENUM, Data/IP Donor network does not incur costs in call routing Less operational costs Long-term solution
Requires Centralized DB High initial Set-up costs

Number Portability Technical SolutionsIndirect or Inter-dependent Routing (Donor network involved
in call routing) Onward Routing
Originating network routes the call to Donor network Donor network determines the right Terminating network Donor network routes the call to the Terminating network
Query on Release Originating network routes the call to Donor network Donor network determines the number is ported and returns this indication Originating network determines the right destination for the number by querying the
DB Originating network routes the call to the Terminating network
Call Drop-back Originating network routes the call to Donor network Donor network determines the number is ported and the right Terminating network Donor network returns this indication of Terminating network to Originating network
and releases the call Originating network routes the call to the Terminating network

Onward Routing
Pros Cons Simple implementation, no Centralized DB needed Donor network can setup its own databases Lower setup costs Short-term solution
Inefficient call routing (originating to donor n/wand donor to recipient n/w call setup needed)
High operational costs Donor network incurs call routing costs

OR Local Yes 2
Dropback Local Yes 1+1 on setup
QOR Central. Yes 1+1 on setup
ACQ Central. No 1
Centralized DB= DB with ported numbers of several operators Local DB = DB with ported-out numbers for the operator
ACQ: most efficient for switching resources used OR: least efficient (and Donor operator has to carry out calls of ported-out subs)
