2. SIEMENS 2 Agenda Introduction NP Overview NP Examples Central Reference Database Discussion

3. SIEMENS 3 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

4. SIEMENS 4 Number Portability is a key feature in deregulated markets Network of operator A Geographical/location portability 1234 Portability Concept Service number portability Service Provider Service Node X 0800123 Service Node Y Network of Operator B 0800123 Network of Operator A Carrier/operator portability Network of Operator A Network Node X 1234 Network Node Y Network of Operator B 1234 Subscriber

11. SIEMENS 11 Possibilities for NP Database NP Database switch integrated (EWSD) Intelligent Network integrated (IN@vantage) SA STP integrated (SURPASS hiS 700) hiS 700 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.

12. SIEMENS 12 National Integration with GNMS Global Number Management System GNMS Central Reference Database

13. SIEMENS 13 Number Portability - Successful Implementation The success of a Number Portability implementation depends on 2 factors: Number Portability - Implementation 2. Administrative Procedure: s One-stop-shopping s Well defined processes s Short execution cycles s Defined porting windows s Short disruption time for change-over s Low error rates s Clearly defined escalation procedures 1. Technical Implementation: s Correct call routing from donor to recipient network s Correct charging

14. SIEMENS 14 sOperators have to co-operate to execute NP processes sNP processes are defined national wide sOperators exchange messages in a defined national protocol sIn the national NP processes operators systems have to be integrated for full automation The National Integration is the focus of GNMS Administration – National Integration

15. SIEMENS 15 Number Portability - Central Reference Database sWhy CRDB? sNational Survey sAuthorized Reference Data (e.g. for new operators) sOperation sby NRA (National Regulatory Authority) sby independent 3rd party on behalf of NRA sby a consortium of the operators (and the NRA) sby independent 3rd party on behalf of a consortium of the operators sby one operator on behalf of the NRA Number Portability - CRDB
