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

11
Its 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

Emerging Importance of Network and Service
Management
From support system to main service stream

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

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

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.
