2 I. Overview I IV. Characteristics of Ubiquitous Converged Network Roles of SP/NP in Ubiquitous Converged Network Integrated of Facility Information Business Agility Next Generation OSS Architecture: NeOSS Benefits of NeOSS Deployment 3 APNOMS2005, Okinawa, JAPAN Characteristics of Ubiquitous Converged Network Characteristics of UCN Diverse CPEs RFID Devices Home Entertainment Devices Network Access Devices Various Access Technologies xdsl FTTH WLAN Mobile Wi-Max (WiBro) DMB Etc Various Services ambiguous until now Current Network Network focus Circuit-based long-lived lived service Reactive to customers Relatively simple product mixture Business drives by Telecom carriers and technologies Ubiquitous Converged Network Service focus Session-based short-lived service Proactive to customers Increasingly complex product mixture Business drives by customers and technologies 4 APNOMS2005, Okinawa, JAPAN 35

3 Roles of SP/NP in Ubiquitous Converged Network Build Ubiquitous Converged Network (UCN) Broadband Convergence Network (BcN) Ubiquitous Sensor Network (USN) Various Access Networks Operations and Maintenance on UCN Integrated management of resource Information Business agility Only an Integrated Network Operation Delivers the Cost Benefits of Ubiquitous Converged Network Customer Self-Provisioning and Self-Operation Control 5 APNOMS2005, Okinawa, JAPAN Integrated of Resource Information Consistent multi-layer layer resource information model - Enhance operations quality by synchronizing physical and logical inventories with networks Support layered network architecture of inter-connecting points among adjacent Layers CPE (Home) Layer Access Network Layer IP Transport Layer Optical Transport Layer Data model for large-scaled database transaction Consolidate customer information with resource information 6 APNOMS2005, Okinawa, JAPAN 36

4 Business Agility Adaptable Network Operations Architecture - Agility is the ability to respond quickly to changes in business environment - Adaptable for accommodating newly emerging ubiquitous converged services that are currently difficult to identify - Able to do faster decision making through better access to operations information Essential features for agile network operations architecture Simplification Standardization Modularity Integration Web Service based Open Architecture (SOA) Business Process (BPM) Enterprise Application Integration (EAI) Business Activity Monitoring (BAM) Compliant with TMForum NGOSS Architectural Principles 7 APNOMS2005, Okinawa, JAPAN I. Overview I IV. Why Built Siloed OSS in KT Problems of Legacy Siloed OSS Objectives for KT Network Operations Next Generation OSS Architecture: NeOSS Benefits of NeOSS Deployment 8 APNOMS2005, Okinawa, JAPAN 37

5 Subscriptions per employee (PSTN, ADSL) The role of OSS becomes more important Request New Service Request budget request Fast development is needed Budget (100 million KW) Services PSTN Megapass Home Digital High Speed Service Kornet Dedicated Line etc Total Contents LLU, Number Portability... ADSL, Nespot, NTOPIA... Home Sky,Home Media.. Public ATM, Public Hinet-P/F.. entum, ISDN,Dial Up,VPN.. Long distance... Octave,Wibro, DU: categories Services Big bang of services Converged services no OpEx Minimizing Time-to to-market Integrated OSS 9 APNOMS2005, Okinawa, JAPAN Why built siloed OSS in KT Narrow Business Domain Main business area until late 1990s : PSTN and leased-line line KT Major OSS Systems PSTN installation support system PSTN assurance support system Leased-line installation & assurance system Transportation network inventory management system High-speed Internet Booming Broadband internet access(xdsl), ATM, FR, VPN businesses so rapidly emerging in 3~4 years KT built siloed OSS for each emerging new service No prepared integrated OSS framework 10 APNOMS2005, Okinawa, JAPAN 38

6 Problems of Legacy Siloed OSS Problems of Siloed System Slow to meet customer demands Revenue leakage Customer churn Competitive pressures Operational inefficiency High operations and maintenance cost Data inconsistency Difficult adaptation to future converged business environments Highly automated and integrated OSS system for business agility 11 APNOMS2005, Okinawa, JAPAN Objectives of KT Network Operations Realization of integrated network operations framework for future ubiquitous converged network Offers maximum support for wireline and wireless Service Fulfillment/Assurance from a single and unified platform Simplifies Fulfillment with an integrated, automated, cost- effective, and flow-through solution Realizes one-stop and flow-through Service Assurance Provides accurate data for inventory management allowing for non-disruptive evolution Enforces customer-centric centric network operations solution by Service Level Agreement Straightens out KT s s legacy issues with future-proof platform that gears up KT for tomorrow s s challenges 12 APNOMS2005, Okinawa, JAPAN 39

8 How does NeOSS Stack Up? NeOSS enables KT to effectively manage all kinds of services including next generation converged services on one common OSS. KT was able to leverage their investments and expertise in OSS/NMS and incorporate appropriate components into NeOSS Incorporate industry standards into NeOSS design Operational functionality of most modules is comparable with many commercial COTS packages NeOSS enables KT to timely enhance their business processes according to the customer demands Real-time business process monitoring and enhancement can be achieved by separation business process from implementation Web Services approach provides NeOSS with the agility necessary to evolve and continue to deliver the management capabilities needed by a sophisticated service provider 15 APNOMS2005, Okinawa, JAPAN I.
