The feature Number Portability allows subscribers to keep their directory number when they move within the same local area or change to another network operator.There exists four basic types of portability:
• Location Portability Change location but keep the Operator and the number.
• Service Provider Portability for Non-geographic Numbers Service numbers (e.g. IN-Services) ported from one operator to another.
• Service Provider Portability for Geographic Numbers Change from one Operator to another, but keep the number.
Portability Concept
• Service Portability E.g. change from POTS to ISDN

Most operators and regulators are opting for a centralized number portability (NP) solution because it guarantees efficient use of network resources and independence from competitors. SA STP integrated NP database is high-performance and innovative solutions that is easy to implement and manage.

Number Portability - Successful Implementation
The success of a Number Portability implementation depends on 2 factors:
Number Portability - Implementation
2. Administrative Procedure:
One-stop-shopping
Well defined processes
Short execution cycles
Defined porting windows
Short disruption time for change-over
Low error rates
Clearly defined escalation procedures
1. Technical Implementation:
Correct call routing from donor to recipient network
Correct charging
14
SIEMENS
Operators have to co-operate to execute NP processes
NP processes are defined national wide
Operators exchange messages in a defined national protocol
In the national NP processes operators systems have to be integrated for full automation
The National Integration is the focus of GNMS
Administration – National Integration

Why CRDB?
National Survey
Authorized Reference Data (e.g. for new operators)
Operation
by NRA (National Regulatory Authority)
by independent 3rd party on behalf of NRA
by a consortium of the operators (and the NRA)
by independent 3rd party on behalf of a consortium of the operators
