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
