abstract = {To address this objective, this thesis first analyzes how NFV allows the MNO
to manage the lifecycle of those RAN slice’s network functions which are virtualized.
Among all the lifecycle operations, this dissertation focuses on the
scaling operation. The reason is the scaling operation comprises the main NFVMANO
management procedures, i.e., adding/removing the virtualized resources
of a VNF instance, and deploying/terminating a VNF instance. In this thesis,
we specifically analyze the different procedures the NFV-MANO may trigger to
automatically scale VNFs. Furthermore, we also propose an ETSI-NFV compliant
workflow that clarifies the interactions and information exchanges between
the NFV-MANO entities for one representative scaling procedure.
The second step to design a 3GPP/ETSI-NFV-based architectural framework
for RAN slicing is to link the 3GPP and NFV templates to automate the lifecycle
management of RAN slices. To that end, we propose a description model that
harmonizes the 3GPP and ETSI-NFV viewpoints on RAN slicing. Specifically,
our model aims to enable the customization and deployment of the virtualized
RAN slice’s constituents over a multi-cellular environment. The proposed solution
benefits from the reusability provided by the NFV descriptors to define the
underlying resources of the RAN slice’s constituents. To customize the behavior
of a RAN slice, the most representative radio parameters to configure its functionalities have been identified. Furthermore, to facilitate the comprehension of
the proposal, we also provide an example of the description of three RAN slices
for eMBB, mMTC and uRLLC services.},
