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

Colombo, Sri Lanka, 7-10 April 2009
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

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

Highlights and proposals from Presentation 3
Efficient 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

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.
