Core network aspects 1

a) A new component network or an enhanced version of an existing one, or

b) A heterogeneous collection of new component networks or of new and existing component
networks that is operated as a single network.
NOTE 1 – The plural form "Future Networks" (FNs) is used to show that there may be more than one network that fits
the definition of a future network.
NOTE 2 – A network of type b may also include networks of type a.
NOTE 3 – The label assigned to the final federation may, or may not, include the word "future", depending on its nature
relative to any preceding network and similarities thereto.
NOTE 4 – The word "difficult" does not preclude some current technologies from being used in future networks.
NOTE 5 – In the context of this Recommendation, the word "new" applied to a component network means that the
component network is able to provide services, capabilities, and facilities that are difficult or impossible to provide using
existing network technologies.
3.2.3 service universalization: A process to provide telecommunication services to every individual or
group of people irrespective of social, geographical, and economical status.

4 Abbreviations and acronyms
This Recommendation uses the following abbreviations and acronyms:

5 Conventions
This Recommendation uses "is recommended" to indicate the main points to be taken into account in the
standardization of FNs. Detailed requirements and their degree ("required", "recommended", or "optional")
need further study.

6 Introduction
While some requirements for networks do not change, a number of requirements are evolving and changing
and new requirements arise, causing networks and their architecture to evolve.
For future networks, traditional requirements, such as promoting fair competition [ITU-T Y.2001], which
reflect society's values, remain important.
At the same time, new requirements are emerging. Numerous research projects have proposed
requirements pertaining to future society [b-NICT Vision] and [b-EC FI], and although there is still a lack of
consensus, it is clear that sustainability and environmental issues will be vitally important considerations over
the long term. New application areas such as Internet of Things, smart grids, and cloud computing are also
