This forum explored the development trends of Next Generation Networks (NGNs) from April 7-10, 2009, in Colombo, Sri Lanka. Moderated by Ghassem Koleyni, the session featured presentations focusing on creating an open service delivery environment, interoperability of CDMA, EVDO, and LTE networks, efficient backhauling strategies using Carrier Ethernet, and development trends in NGN technology. Key discussions included service platform concepts, the implications of Fixed-Mobile Convergence (FMC), and the essential role of service-oriented architectures (SOA) for new revenue opportunities in the telecom industry.

  1. FORUM ON NEXT GENERATION STANDARDIZATION (Colombo, Sri Lanka, 7-10 April 2009) Development trends of NGN technology and systems Session Moderator Ghassem Koleyni

  2. Presentations and presenters • Session 6P1: Towards an open service delivery environment/platform in NGN (Mr. Marco Carugi, Nortel, France) • Session 6 P2: CDMA / EVDO/ LTE Interoperability and migration plans (Mr. B.V.Raman, CDG, India) • Session 6 P3: Efficient Backhauling Strategies for NGNs using Carrier-Ethernet (Mr. SIVA RAMAMOORTHY, Tejas Networks, India) • Session 6 P4: solutions(Mr. Sethu Raman, Huawei Technologies, India)

  3. Session 6 objectives Presentation of the relevant technologies on NGN accesses, service platforms, home, office and mobile applications with special focus on convergence. Moreover, charging and accounting principles for NGN, it will also look at migration scenarios for NGN and accounting principles for NGN the Management of end-to- end voice QoS in NGN and NGN terminal equipment standardization.

  4. Highlights and proposals from Presentation 1 Towards an open service delivery environment/platform in NGN • Standard reusable “capabilities” as service enabling toolkit • ITU-T’s NGN has identified a reach capability set • Towards an NGN Open Service Environment for flexible and agile service creation, execution and management • Service platform concept • “Rapid change” is key for satisfying changing customer needs • New business opportunities • Opening the NGN via an enhanced Service Oriented Architectures framework (Telco SOA) and Web Services (WS) as implementation tool set of this framework • Exposure of Network capabilities to Applications via Telecom APIs • New requirements of a Telco SOA and related WS enhancements • SOA and WS will enable new business revenues within the integrated IT and Telecom environment • ITU-T is working in this direction • standards convergence and harmonization are essential • ITU-T collaboration with other SDOs has started to integrate relevant specifications with the NGN standardization framework

  5. Highlights and proposals from Presentation 2 CDMA / EVDO/ LTE Interoperability and migration plans • CDMA and OFDM are different technologies with different capabilities • OFDM-based backhaul, broadcast and broadband networks will complement CDMA2000 • Adoption of wider-bandwidth OFDM-based solutions will vary from Market to Market • Wide bandwidth OFDM-based networks will complement 3G broadband networks for Broadband

  6. Highlights and proposals from Presentation 3Efficient Backhauling Strategies for NGNs using Carrier-Ethernet • Increased bandwidth demand as a result of emerging IP applications • While data traffic has grown drastically, revenues have decreased • Carrier-Ethernet Transport for NGN Backhaul • Sophisticated Carrier grade Ethernet transport solution • Carrier grade management and reliability • Evolve gracefully, keep revenues ahead of costs • Lower Operations and training costs

  7. Highlights and proposals from Presentation 4 Development trends of NGN technology and solutions • Ubiquitous network is becoming the foundation of today’s Digital society and Wireless and IP play important roles as technology enablers. • Fixed-Mobile convergence solutions and all IP-network is a MUST for the telecom industry to address the needs of the society and bring cost effective communication to the users. • Both FMC and all-IP transformation will impact all network layers and affect the end-to-end service process. • FMC is a long term system engineering project, which requires well planned and pragmatic approach towards full convergence. • All IP means complete use of packet technologies and complete migration to packetisation. • A step wise migration is a prudent way for operators to implement FMC and all IP transformation.

  8. Conclusions / Recommendations • Towards an open service environment in NGN for flexible and agile service creation, execution and management • SOA and WS will enable new business revenues within the integrated IT and Telecom environment • Wide bandwidth OFDM-based networks will complement 3G broadband networks for Broadband • While data traffic has grown drastically, revenues have decreased • Both FMC and all-IP transformation will impact all network layers and affect the end-to-end service process. • FMC is a long term system engineering project, which requires well planned and pragmatic approach towards full convergence.
