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

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 services
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
