Outline Market and Regulatory Drivers Key Requirements for Number Portability Role and Involvement of Regulators

Number Portability Network Options


3/17

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

Key Requirements for Number PortabilityETSI/3GPP Standards relevant to Number Portability

ETSI TS 122 066 V4.0.0 (2001-03) Digital cellular telecommunications system (Phase 2+) (GSM); Universal

Mobile Telecommunications System (UMTS); Support of Mobile NumberPortability (MNP); Service description; Stage 1

ITU-T Recommendation Q.769.1 (1999) Signalling system No. 7 ISDN user part enhancements for the support of

Number Portability.

ITU-T Recommendation Q.850 (1998)

Usage of cause and location in the digital subscriber signalling systemNo. 7 ISDN user part . ITU-T Q-series Recommendations - Supplement 5

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?)

Number Portability Technical SolutionsDirect Routing

All Call Query Originating network determines the right destination for a number Originating network directly routes the call to Terminating network


10/17

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


12/17

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
