3 Unleashing the potential of the Internet of Things

3.1.3 emergency telecommunications (ET) [ITU-T Y.2205]: Any emergency-related service
that requires special handling from the next generation network (NGN) relative to other services.
This includes government authorized emergency services and public safety services.

3.1.4 Internet of things (IoT) [b-ITU-T Y.2060]: A global infrastructure for the information
society, enabling advanced services by interconnecting (physical and virtual) things based on,
existing and evolving, interoperable information and communication technologies.

NOTE 1 – Through the exploitation of identification, data capture, processing and communication
capabilities, the IoT makes full use of things to offer services to all kinds of applications, whilst ensuring that
security and privacy requirements are fulfilled.
NOTE 2 – From a broader perspective, the IoT can be perceived as a vision with technological and societal
implications.
3.1.5 next generation network (NGN) [b-ITU-T Y.2001]: A packet-based network which is
able to provide telecommunication services and able to make use of multiple broadband, QoS-
enabled transport technologies in which service-related functions are independent from underlying
transport-related technologies. It enables unfettered access for users to networks and to competing
service providers and/or services of their choice. It supports generalized mobility which will allow
consistent and ubiquitous provision of services to users.

5 Conventions
In this Recommendation:
The keywords "is required to" indicate a requirement which must be strictly followed and from
which no deviation is permitted if conformance to this document is to be claimed.

The keywords "is recommended" indicate a requirement which is recommended but which is not
absolutely required. Thus this requirement need not be present to claim conformance.

The keywords "can optionally" and "may" indicate an optional requirement which is permissible,
without implying any sense of being recommended. These terms are not intended to imply that the
vendor's implementation must provide the option and the feature can be optionally enabled by the
network operator/service provider. Rather, it means the vendor may optionally provide the feature
and still claim conformance with the specification.
The keyword "disaster" indicates any kind of critical situation or emergency with natural or man-
made origins.
The keywords "IoT device" indicate a device in IoT environment.
