Technological Drivers
•
Obsolescence of legacy networks,
plus cost and complexity of
managing multiple legacy
networks.
•
Lower capital and operational
expenses. Increased
centralisation of routing, switching
and transmission, lower
transmission costs over optical
networks.
•
IP-based networks enable the
provision of cheaper VoIP
services as a replacement for
PSTN voice services.
•
IP-based networks enable the
provision of a wider range of
services, and allow bundling of
services (triple and quadruple
play).
•
Evolution and convergence of
terminal equipment.
Social Drivers
•
Demand for innovative, high-
bandwidth, services (HDTV, VoIP,
etc).
•
Demand for more targeted or
personalised content (on demand
multimedia services, mobility).,
•
Demand for increased
interactivity: possibility to interact
actively with the service, growing
interest for user-created content.
•
Demand for evolved and more
flexible forms of communications,
including instant messaging,
video-conferencing, P2P, etc.
•
Business demand for integrated
services, in particular in case of
multi-national structures, which
need to link different national
branches, guaranteeing a flexible
and secure access to centralised
resources and intelligence.
In this context, the migration from separate network infrastructures to next generation core networks
is a logical evolution, allowing operators to open up the development of new offers of innovative content
and interactive, integrated services, with the objective to retain the user base, attract new users, and
increase ARPU (see Box 3). NGN is therefore often considered essential for network operators to be “more
than bit pipes”
28
and to strategically position themselves to compete in the increasingly converged world of
services and content, where voice is no longer the main source of revenue, and may become a simple
commodity. The investment in next generation access networks – both wired and wireless – will be
necessary in order to support the new services enabled by the IP-based environment, and to provide
increased quality. At the same time, the important investment necessary to develop next generation
infrastructures brings about new economic and regulatory issues, which will be analysed in the following
sections.
