KTKTChanges in telecom operational environment

Explosive expansion of Internet and increase of users Advent of many CLECs and ISPs in Internet business areas

Competition Sophiscated customer requirements Various IP networks and services

Various OSSs were developed to meet the needs for individual networks and services management, which resulted in Proliferation of independent legacy OSSs Increased OPEX


KTKTIP network is evolving so fast …

Core : faster, traffic engineered Edge : focus on QoS management

KTKTManaging new IP networks (2)

Increased requirements for network management DiffServ + MPLS management Traffic volume management

End-to-end flow management using NetFlow and/or sFlow Integration of network and server management

Increased requirements for security management Management of anomalous traffic Separation of management network from service network


KTKTWhy should current OSS be redesigned ?

Current Systems are unable to support new IP services Can not deliver premium services such as BoD, QoS/SLA guarantee and security se

rvices So many OSSs developed on different platforms and different data models

Data integrity and maintenance problems exist System development/Integration takes relatively longer time and is very expensive

and risky Can not meet time to market requirement

KTKTOur goal to a New OSS (NeOSS)

Reduced time to market by Applying a common platform

Improved data integrity by Applying a common data model Single data entry but multiple uses

Providing new functionalities to customers and operators Single sign-on Pre-ordering Order tracking SLA management Enhanced work force management On-line management of field information One-stop handling of customer service requests

Single point of contact Reduction of service provisioning and fault handling time

KTKTConcluding remarks

New operational environment requires a new (next generation) OSS which will enable

Reduced time to market Faster system development speed

Flexibility in a changing business environment

Improved service provisioning and maintenance accuracy

Ensured data integrity

Automated work order processing

Keeping customers satisfied More information for customers on performance and usage

Ensured customer service level by pre-ordering, order tracking and trouble tracking, etc.


KTKT

Next generation is just around the corner.

Now is the right time to start the development

of a New (next generation) OSS.
