1 Scope
This Recommendation provides the functional architecture of software-defined network intelligence
capability enhancement (S-NICE), S-NICE is a specific implementation of network intelligence capability
enhancement (NICE) [ITU-T Y.2301] making use of software-defined networking (SDN) technologies. This
Recommendation defines the functional architecture of NICE implementation making use of SDN
technologies, describes the enhancement functions based on NICE, the reference points among different
functions and some typical implementation flows.

3 Definitions

3.1 Terms defined elsewhere
This Recommendation uses the following terms defined elsewhere:

3.1.1 application [b-ITU-T Y.101]: A structured set of capabilities which provide value-added functionality
supported by one or more services.

3.1.2 content [b-ITU-T H.780]: A combination of audio, still image, graphic, video, or data.
NOTE – A variety of formats is classified as "data" (e.g., text, encoded values, multimedia description language
introduced by [b-ITU-T H.760]).
3.1.3 context [b-ITU-T Y.2002]: The information that can be used to characterize the environment of a
user.

NOTE – Context information may include where the user is, what resources (devices, access points, noise level,
bandwidth, etc.) are near the user, at what time the user is moving, interaction history between person and objects,
etc. According to specific applications, context information can be updated.
3.1.4 identity [b-ITU-T Y.2720]: Information about an entity that is sufficient to identify that entity in a
particular context.
3.1.5 network intelligence capability enhancement (NICE) [ITU-T Y.2301]: An enhanced NGN supporting
some intelligent capabilities for the provisioning of services according to requirements of users and
application providers. These intelligent capabilities (termed as "NICE capabilities") enable operators to assign
and dynamically adjust specific network resources based on the requirements, as well as support interfaces
for users and applications enabling on demand resource and service provision.
3.1.6 service [b-ITU-T Y.2091]: A set of functions and facilities offered to a user by a provider.
