telecom service market share
Telecom Service Market Share

December,1998

  • Telecommunication services created over $20 billion in 1998
  • Wireline & Wireless - 80% of market share

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

  • Cellular services : Two competitive suppliers ,SK and Shinsegi
  • PCS :Three competitive suppliers, FreeTel, LG and Telecom

Outline
  • Changes in Telecommunication Market
  • Impacts on Telecommunication Network Management
  • Meeting the Challenges
  • Conclusions
it s diverse and fast changing
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

emerging importance of network and service management
Emerging Importance of Network and Service Management

From “support” system to main service stream

- customer interaction,

- CNM

operations “support” system

- service

provisioning

- flow-through.

mgmt,

virtues of the upcoming management systems
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
integrated management
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

Dynamic Integration Framework as Additional Common Frameworks

  • Avoiding direct, ad hoc integration

component and middleware technology
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
standardization on network management
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

working with legacy systems
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
in conclusion
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.
