EMPOWERMENT
MECHANISM
(NEM)
NEM = use of relevant method to solve a concrete operational problem
in a specific networking environment
o e.g. use of genetic algorithm for interference coordination in LTE
networks
NEM = a real autonomic function controlling network resources
93rd ETSI Workshop On Future Network Technologies, 9-11 April 2013, Sophia Antipolis
NEM SKIN = unified abstraction of NEM
o common set of objects describing its properties and capabilities
e.g. manifest, mandate, instance description
o common set of interfaces to connect and interact with the UMF
and other NEMs
o set of technology-specific adaptors
NEM SKIN = vector of unification, re-usable software component, and
an accelerator for NEM implementation

3 core functions:
o governance, coordination, knowledge
o and associated mechanisms e.g. conflict avoidance, data mining…
Responsible for:
� The interaction between human operator and
its network→ express business goals report on
critical states of self-managed
operations/devices
� Driving NEMs’ behavior→ policy-based
framework for translating business-level,
service specific goals/requests into low level,
policies and configuration commands

policies and configuration commands
GOVERNANCE �������� NEM:
� Commands to set NEM’s status/mode (e.g.
active, idle, stopped) and configure its
operational parameters.
� Report on the NEM’s operational conditions
and configuration characteristics (e,g.
performance indicators,
capabilities/behaviour, interaction with other
NEMs).
Functional decomposition
3rd ETSI Workshop On Future Network Technologies, 9-11 April 2013, Sophia Antipolis
Responsible for:
� Prevent the network from instabilities and
side effects due to the multiple NEMs running in
parallel
�Ensuring the proper sequence in triggering of
NEMs, their stable operations, and conditions
under which they will be executed taking into
account:
� Operator and service requirements,

� Operator and service requirements,
� Needs for Conflict avoidance, joint
optimization and stability control.
COORDINATION �������� NEM:
� Commands to drive coordination including:
tokens, timing, constraints, status
(active/idle), etc.
� Information on the NEMs operation
including: parameters, metrics, scope, utility
functions, etc.
