Core network aspects 1

In S-NICE, the service control capability is one of the S-NICE orchestration capabilities, and it is required to
support "on demand" configuration in order to provide "dynamic" resource control, registration,
authentication, and authorization capabilities at the service level, upon request of applications. For example,
if a user asks for high quality of service (QoS) level during an ongoing service session of an application when
the user feels unsatisfied of the delivered QoS, then the service control capability of S-NICE selects the
appropriate S-NICE controller capabilities to adjust the network resources in order to fulfil the user's
requirement immediately.

6.3 Requirements of open environment
In NICE, the open environment capability supports the invocation by developers and applications of NICE
capabilities, such as the policy control capability and the traffic scheduling capability, via standard application
programming interfaces (APIs).

In S-NICE, the open environment capability is one of the S-NICE orchestration capabilities, and it is required
to enable developers and applications to take full advantage of the S-NICE controller capabilities, such as
virtualized network information abstraction, S-NICE controller(s) selection, and status monitoring. It is also
required to support openness of content and context analysis information to developers and applications.
Moreover, it is required to provide APIs to developers and applications for openness of S-NICE controller
capabilities.

6.4 Requirements of content and context analysis

In NICE, the content and context analysis capability receives the awareness related information from the
content and context detection capability and deeply analyses this information. The content and context
analysis capability supports processing and storage of content and context information and distributes user
traffic analysis results and network status analysis results to the requestor of content and context
information, such as the policy control capability and the traffic scheduling capability. Moreover, the
interaction between the NICE content and context detection capability and the NICE content and context
analysis capability is based on management configuration.
In S-NICE, the content and context analysis capability is required to provide user traffic analysis results and
network status analysis results to the S-NICE controller capabilities and the S-NICE orchestration capabilities.
The analysis results include not only user traffic, users' service preferences and network status, but also
abstracted information of physical and logical transport networks. Based on the analysis results, the S-NICE
controller capabilities and the S-NICE orchestration capabilities configure, manage, secure, and optimize the
network resources.
In S-NICE, the transfer of all the detected information from the content and context detection capability to
the content and context analysis capability, and the transfer of detection rules from the content and context
analysis capability to the content and context detection capability are required to support SDN related
protocols.

6.5 Requirements of policy control

In NICE, the policy control capability receives analysis results regarding user, traffic, and network information
from the content and context analysis capability while it also receives the application's bandwidth and QoS
assignment requirements from the service control capability and the service user profile (SUP) capability. The
policy control capability makes policy information decisions and updates, and then sends the results of these
policy decisions and updates to the policy enforcement capability. The policy control capability also makes
decisions regarding network resource and admission control, supports unified policy database and consistent
policies definitions, and supports a variety of access and core networks within a general resource control
framework.

In NICE, the policy enforcement capability is based on pre-defined rules and receives policy control
requirements from the policy control capability.
In S-NICE, the policy control capability is one of the S-NICE controller capabilities. The control policies are not
only concerning access control, bandwidth management, and QoS level, but also security, reliability, energy
