2. Outline • Changes in Telecommunication Market • Impacts on Telecommunication Network Management • Meeting the Challenges • Conclusions

3. 3+1 Drivers for Changes in Telecommunication Business Environment Competition by Regulation Customer Demands Internet Technology Advances

4. IT Industry in Korea unit: billion Won

5. Fixed telephone service Cellular & PCS Internet service users Telecommunication Service Penetration/Population 50 Penetration (%) 40 30 20 10 - 2002 2003 1997 1998 1999 2001 2000 1996

6. Telecom Service Market Share December,1998 • Telecommunication services created over $20 billion in 1998 • Wireline & Wireless - 80% of market share

7. Market Share (wireline telephone) * Fixed telephone market Includes Local, Long distance and International telephone Service. • Dacom shares 8% in long distance and 19% in international telephone service market. (Onse shares 2% and 9% ) • Hanaro is expected to take 4% of total local market revenue at the end of 1999

8. Market Share (wireless service) • Cellular services : Two competitive suppliers ,SK and Shinsegi • PCS :Three competitive suppliers, FreeTel, LG and Telecom

10. Outline • Changes in Telecommunication Market • Impacts on Telecommunication Network Management • Meeting the Challenges • Conclusions

11. It’s Diverse and Fast Changing • Demands are met by introducing new networks and services • resulting in diversity in networks and services • The speed of change is getting faster • making it difficult to catch up with existing paradigm No more ad hoc, case-by-case approach Need for systematic, framework-based solution

12. Emerging Importance of Network and Service Management From “support” system to main service stream - customer interaction, - CNM operations “support” system - service provisioning - flow-through. policy-based mgmt,

13. Virtues of the Upcoming Management Systems • Integrated management for handling diversity • Dynamic configurability for fast adaptation to changes • fast adaptation of newly emerging networks and services • Emphasis on service management • Management system as the core for business information, decision making, and quality management

14. Integrated Management • Different integration contexts • integration of management functions, • integration of network elements with different management interfaces, • integration of client-server networks (e.g., IP and ATM networks), • network and service integration, • service composition, • etc. • Different integration patterns and methods • no well-proven, widely-accepted framework for integration • need for common integration framework that supports faster application integration

15. Dynamic Configurability scale up/down of existing networks and services new/modified service type new/modified network type Components + Configuration Framework

16. Emphasis on Service Management CNM flow-through operation • service provisioning • service monitoring for • proactive management

17. Business Support • source of valuable business data for • - business support system • - network planning and dimensioning • - advanced customer care • - generating new service • base system for maximizing telecom • business value • tight and seamless integration with • business data warehouse • business support • system • network planning • system network & service management system

19. entity 1 entity 1 entity 2 entity 2 entity 3 entity 3 ... entity n entity n Dynamic Integration Framework as Additional Common Frameworks • dynamic integration framework in • addition to existing management • frameworks. • Avoiding direct, ad hoc integration • approach • Mediation-based framework supported • by meta level information on networks • and services dynamic, ad hoc approach mediated integration approach integration coordination entity meta level information : integration relationship

20. Component and Middleware Technology • Using component technology is becoming virtually the common practice for rapid development of management systems • e.g., Corba-based network management system • component technology is evolving, making development more easier and secure (e..g, Enterprise JavaBeans and Corba Components) • For telecom operators to get more benefit from the technology… • Continuous generation, publication, and standardization of management components is encouraged. • enables operators to focus more on business-related activities

21. Standardization on Network Management Top-down Approach business level • business-driven • direct benefit to • network/service • providers service level network level • per-technology • vendor-driven network element level Bottom-up Approach

22. Working with Legacy Systems • Legacy systems as “another” component of the whole management system • importance of adapters • Coping with monolithic structure of legacy systems • service management and network management features merged into a single but optimized mass • different abstractions rather than modifying the internals of legacy systems • service management level mediator • network management level mediator

23. In Conclusion • The telecommunication world is rapidly changing. • Changes in telecommunication world is pushing for more role in telecommunication network management systems. • The need for common framework for dynamic integrated network management system. • Importance of common management components.
