Portability Concept
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 Geographic Numbers
Change from one Operator to another, but keep the number.
• Service Provider Portability for Non-geographic Numbers
Service numbers (e.g. IN-Services) ported from one operator to another.
• 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 - Implementation
Number Portability - Successful Implementation
The success of a Number Portability implementation
depends on 2 factors:
1. Technical Implementation:
2. Administrative Procedure:
 Correct call routing from donor
to recipient network
 One-stop-shopping
 Correct charging
 Short execution cycles
 Well defined processes
 Defined porting windows
 Short disruption time for
change-over
 Low error rates
 Clearly defined escalation
procedures
13
Administration – National Integration
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

Number Portability - CRDB
Number Portability - Central Reference Database

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
 by one operator on behalf of the NRA
