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.Colombo, Sri Lanka, 7-10 April 2009 3

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 setTowards 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 needsNew 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 APIsNew requirements of a Telco SOA and related WS enhancements

SOA and WS will enable new business revenues within the integrated IT and Telecom environmentITU-T is working in this direction

standards convergence and harmonization are essentialITU-T collaboration with other SDOs has started to integrate relevant specifications with the NGN standardization framework

Highlights and proposals from Presentation 2 CDMA / EVDO/ LTE Interoperability and migration

plans CDMA and OFDM are different different technologies with different capabilitiesOFDM-based backhaul, broadcast and broadband networks will complement complement CDMA2000Adoption of wider-bandwidth OFDM-based solutions will vary from Market to MarketWide bandwidth OFDM-based networks will complement 3G broadband networks for Broadband

Highlights and proposals from Presentation 3 Efficient Backhauling Strategies for NGNs using

Carrier-EthernetIncreased bandwidth demand as a result of emerging IP applications While data traffic has grown drastically, revenues have decreasedCarrier-Ethernet Transport for NGN Backhaul

Sophisticated Carrier grade Ethernet transport solutionCarrier grade management and reliabilityEvolve gracefully, keep revenues ahead of costsLower Operations and training costs

Highlights and proposals from Presentation 4 Development trends of NGN technology and

solutionsUbiquitous 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.
