Number Portability and Telecommunications Liberalization
CANTO 2005
Agenda
Introduction to Number Portability
National Number Portability Design Issues
Case Studies
Tactics for a Successful Roll-out
Introduction to Number Portability
Goals and Design Basics
Number Portability Goals
Enable customer to keep their phone numbers while switching from one service provider to another
Principle #1 – The customer owns the telephone number
Promote competition through unfettered consumer choice Principle #2 – Consumers should have minimal inconvenience in
porting a number
Encourage investment in local telecommunications infrastructure through level competitive playing field
Principle #3 – Regulations should ensure equal opportunity for network operators
Encourage migration to new technologies with consumer-friendly migration paths
Principle #4 – Number portability mechanics should be available for both inter-operator competition, and for intra-operator service migration
National Roll-out Design Basics
Determine call routing mechanics
Predominate method is “Direct Routing”
Terminating network element is determined by the “N-1” operator
Look-up performed in a complete database of all ported numbers
Determine order negotiation method
Consumer must have clear method to indicate intention
Operators must be able to confirm consumer intent
Operator must be able to clearly agree on migration details
Migration data must be executed and published

Porting Timeline
There is a timeline of activities that must occur for each port
Target porting time is a major design consideration
Short times consumer convenience and system complexity
Long times consumer frustration and system simplicity
Short Timeline Activities
Consumer initiates port request with receiving operator
Receiving operator presents port request with credentials to donating operator
Donating operator confirms credentials and proposed timeframe
Receiving operator presents routing transfer parameters and final timeframe
Donating operator confirms routing data and final timeframe
Receiving operator activates the service
Receiving operator broadcasts routing data to all network operators
All within 3 hours!
National Number Portability Design considerations Implementation Issues:
Method used by consumer to initiate a port request
– One Stop or Two Stop– Automated or Manual
Method to Route Calls
– Direct/All Calls Query, Indirect Rerouting, variations Method used to specify routing parameters
– Clearinghouse or Bilateral Method used to broadcast activation information
– Real-time or Batch Method for cost recover
– Porting parties pay or All subscribers pay

10 USA 2003 Centralized N/A 8 Million in 2004
MNP Case Study 1 - USA
Mobile Number Portability introduced in 2003
Delayed twice to allow operators additional time to prepare
Used a “mature” system for network porting activities
Used a new system for ordering activities
8 Million Customers ported their numbers in the first year
Most customers ported to the largest mobile operator (Verizon Wireless) and one of the smallest mobile operator (T-Mobile)
Local Conclusion: Successful
Key Success Factors
– Automated porting process– Time taken for porting was small (few hours to a couple of days)– Fixed to mobile, mobile to mobile was introduced nationwide at the same
time Outcome: High port counts, high customer satisfaction
MNP Case Study 2 - UK
Mobile Number Portability introduced in 1999
3% of the Mobile subscribers ported their numbers
Local Conclusion: Not Successful
Key Causes
– Longer porting durations (up to 7 days)– Customers were charged to port away (in some cases 30 GBP, eventually
dropped)– Two step porting process impacted customer convenience
Outcome: Low port counts, low adoption rate, little impact on competition
Effect on Service Providers – Revenue Data Source – public financial data for top 100 world-wide telecommunications providers
Conclusion – Number Portability involves investments, but companies in that environment fared better

National Preparation Timeline
15 - 18 Months Prior Solidify regulations Organize collaborative organization for evaluating porting model
12 Months Prior Determine porting model
– Geographic/Jurisdictional scope of valid port requests– Evaluate use of US/Canada NPAC system– Evaluate need for multi-jurisdictional centralized processing systems
9 Months Prior Settle on porting standards
6 Months Prior Finish central system(s) preparation, begin acceptance testing
3 Months Prior Finish local system(s) preparation, begin interoperability testing
Go live
Plan on close monitoring for 6 to 12 months after
Number Portability in Caribbean
Will require extensive preparation Plan on 12 to 18 months lead time Clarify regulations Establish a viable implementation model Involve all operators, regulators, and effected vendors
Will require specialized knowledge & technology Operating central clearing house Adapting sub-systems to support portability Processes
Will require investment Infrastructure investment Software investment People investment
Common Market approach will provide best leverage for the investment
Number Portability in Caribbean
Benefits:
Consumer choice
Fair-Playing Field Competition
Improved service levels from operators
Introduction of new, innovative services
Increased motivation for infrastructure investment
