1. 09/09/2015 1 NGN implementation aspects on the developing market in Poland IP/Optical Workshop Chitose, 9-11 July 2002 Telekomunikacja Polska Jacek Olejnik Janusz Pieczerak

2. 09/09/2015 2 Poland and Telekomunikacja Polska Poland is located Central Europe Population- 38,6 M GDP growth rate- 2,5% Annual inflation- 5,4% Unemployment rate- 19% Telekomunikacja Polska acts as national operator Market share: international calls- 98% long distance calls- 78% local calls- 92 % data transmission- 50% Market penetration: fixed - 31% mobile - 33% Telephone density: 27 main lines/100 inh. Polish market situation: 12 local operators 3 mobile operators 12 long distance operators 50 Internet Service Providers

3. 09/09/2015 3 TP development historical operator since 1930’s established in 1992 as state-own company from 1992 havy investments due to credits from World Bank pressure from customers Internet impact successive market deregulation still 1,5 M of subscribers of analog exchanges possible problems with existing software systems upgrades TP Capital Group: TP ( 10 M of subscribers) PTK Centertel - mobile operator (3 M of subscribers) TP Internet - internet provider

4. 09/09/2015 4 Next Generation Network simplify network architecture - network layers - protocols obtain manufacturer independence - standard API - independent layer development easy scalability convenient creation of new services flexible interconnection with competitors - possible source of profit integration with other information technologies - TV, radio, knowledge databases - computer networks unified multi-service network What we expect from NGN technology:

5. 09/09/2015 5 NGN - development level huge literature evolution of concept - manufacturers, operators, customers standardisation still on going no complex implementations - TDM still cheaper - traditional voice makes profit - new services should balance cheep packet voice successive step in telecommunication different opinions from companies - maintenance costs of existing infrastructure - implamentation costs - no ‘killer application’ doubts about the return on investment State of the art.:

6. 09/09/2015 6 NGN implementation organisational aspects economical aspects technical aspects NGN implementation seems to be the necessary step in developing of telecommunication infrastructure, but during the discussions about the concept we realised potential threats:

7. 09/09/2015 7 NGN implementation actual distributed TP organisation dependent on technologies should be redefined - coexistence of new and old technologies can create new challenges - fast technology development requires dynamic and flexible organisations Organisational aspects

8. 09/09/2015 8 NGN implementation CAPEX and OPEX balance to keep growth of profit diversified service level agreement Economical aspects

9. 09/09/2015 9 NGN implementation integration with existing technology forms hybrid architecture new tasks to manage of hybrid network structure and assure security interoperability between systems plan of simplification of the network can cause complication first possibility to define QoS level due to customer’s requirements and opportunities Technical aspects

10. 09/09/2015 10 NGN - typical architecture

11. 09/09/2015 11 TP start to NGN define main assumptions NGN scenarios request for information tests and selection CBR (TP S.A. R&D) started NGN project to check the real possibilities (in cooperation with France Telecom R&D):

12. 09/09/2015 12 TP start to NGN define main assumptions NGN scenarios request for information tests and selection We are going to check the real possibilities: - minimize investment in non NGN technology - progressive consolidation into unified multi-service packet network - avoid to disturb existing functionality management services Intelligent Network - customers shouldn’t be forced to change existed equipment - reserve necessary period for migration to confirm stability and reliability of the solution

13. 09/09/2015 13 TP start to NGN define main assumptions NGN scenarios request for information tests and selection We are going to check the real possibilities: - transit: interconnecting narrowband switches over packet core network - access: voice only services for areas served by analog exchanges - access: voice and data services with advantages of xDSL technology - access: integrated access merging voice and data services in a single infrastructure - demand models: theoretical network models for getting information about prices, to get ability to compare solutions on economical level

14. 09/09/2015 14 TP start to NGN define main assumptions NGN scenarios request for information tests and selection We are going to check the real possibilities: - request for information to 14 companies - evaluation criteria - methodology of comparison of answers: 1st step: subdomain analysis - referring to certain equipment (VAG, TCS...) 2nd step: domain analysis - referring to scenarios, services, management, economical analysis, migration strategy 3rd step: solutions rating - analysis of answers - classification of the solutions - ranking of companies We are here now !

15. 09/09/2015 15 TP start to NGN define main assumptions NGN scenarios request for information tests and selection We are going to check the real possibilities: - evaluation lab tests (preliminary) - working out of Operator’s Technical Requirements for NGN - selection of NGN suppliers - validation lab test (compatibility with Operator’s Technical Requirements) - integration lab tests - implementation support

16. 09/09/2015 16 TP view on NGN the base of new technology equipment oriented architecture forced by manufacturers new equipment - source of costs gives meaning to new technology functional architecture customer/operator needs oriented new services - source of profit lack of ‘killer application’ concept... technical approach...... functional approach... Summarising our work we want to balance... ?... to answer the main question To NGN or not to NGN?
