our aims• real and effective competition• genuine choice for users• lower prices• higher quality• more innovative services• constructive co-operation with
– international bodies– governments – regulators

NGN definition (ITU-T)• a Next Generation Network is a packet-based network
able to provide telecommunication services, able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies.
• it offers unrestricted access by users to different service providers
• it supports generalised mobility which will allow consistent and ubiquitous provision of services to users

NGN definition (ETSI-TISPAN)• a multi-service, multi-protocol, multi-
access, IP-based network• secure, reliable and trusted• an enabler for Service Providers to offer:
– real-time communication services– peer-to-peer and client-server– nomadicity and mobility of both users
and devices– interoperability between legacy and
next generation services and networks
• regulatory compliance (e.g., lawful interception, number portability and emergency services)

etInterested parties
• Operators:– cost savings – new services and revenues– possibility of a new regulatory
environment
• Enterprises:– fast return on investment– new value-added functionalities
• Consumers:– lower prices– life-style choices– exciting devices and services

outstanding issues• continuing power of incumbents
(some have already an NGN like internal network)
• possible creation of oligopolies
• Long distance and local loop unbundling
• Multi services networks

etA possible scenario
• access via one single line (broadband) • using several devices: from the classical
telephone, to TV set, PC, video and multimedia boxes
• easy access to the Internet at high speed
• high quality video, general entertainment
• interactive learning• new services (to be invented) .....

etA possible scenario
• From the users’ perspective, the convergence of services will enable the emergence of the seamless service concepts, where users can access their “tailored set” of services from any type of access network.
• End-to-end QoS is one of the most important user requirements

etA possible scenario
• connecting inanimate objects to networks
• networks and networked devices become ubiquitous
• electronic tags (e.g. RFID) and sensors extend the communication and monitoring potential of the “network of networks”

etNot simply a new network
• fixed broadband:– corporate– residential
• wireless broadband networks:– Wi-Fi– WiMAX
• cellular voice and data networks• digital broadcast networks (DAB,
DVB, terrestrial, satellite, handheld)• (re-)distribution (Wi-Fi and UWB):
– office and residential– Personal Area Networks (PANs)– car networks

etSome technical problems for interconnection
• Latency – the time it takes a bit of data to get
through a network link• jitter
– the weighted average of the latency difference between every pair of consecutive packets received
• jitter particularly affects the performance of real-time applications such as streaming video and audio

etSome technical problems for interconnection
• If latency and jitter are tuned by each Operator in order to supply a good QoS to their customers, interconnection with other Operators’ networks may produce poor overall performance and decrease dramatically the QoS

Loch Lomond Accord• agreement from 1997-98 between
users and VPN providers• service management and end-to-
end fault diagnosis and ownership• administration and billing:– one stop shopping– one stop billing• synchronised private numbering
for On-net to On-net calling• calling line identification (CLI) and
ringback-when-free

Standardisation• very complicated work at:
– ITU SG 13– ETSI TISPAN– 3GPP– etc.
• impossible to assess:– user needs– implications of standardisation
• driven by:– manufacturers– operators

interconnection
• well established rules for:– conventional networks– IP data networks
• for NGNs interconnection we must refer to:– price– quality of service– interworking

interoperability• services must be available on the
networks to which users have access• devices and networks must interwork• network selection criteria:
– the cheapest– the best quality– security – reliability
• Administrative and billing implications

interoperability• relating to network capabilities:
– Network Address Translators and firewalls– routing tables– Quality of Service capabilities and
interconnect– network coverage– termination capabilities
• related to accessing services and content:– unnecessary software and service bundles– tunnelling– filtering mechanisms and digital rights– end-user devices– content

interoperability• relating to user information:
– authentication, single log-on and user profile management
– customer billing information– access to customer information
systems– resolution of names and numbers
through customer identity systems– functions for determining location

conclusion• NGN: one network paradigm is not
appropriate• NGN creates complex problems of:

conclusion
For Users, some principle must be fullfilled:
• Cost orientation• Widest choice• Transparency in QoS and tariffs• Opt-in ruleUsers expect a demand driven
mechanism, but, until now, little evidence of that
