the inter-working between control planes of the two
domains, allowing a more efficient management of available
resources. Radio resource utilization benefits from the centralization
of mobile network functionalities with the application
of high-order functional split options by fronthauling. However,
higher-order options require larger bandwidth and lower latency
in the fronthaul. Advanced mechanisms for the joint control of
the access network represent the sole solution to support such
fronthaul requirements. This paper proposes a new cooperation
scheme to manage the adaptive flexible functional split in 5G
networks conditioned to the resource availability in the optical
access network. Results show that the proposed converged
approach guarantees the optimal allocation of optical resources
through a software defined wavelength and bandwidth allocation.
The proposed scheme adapts to current traffic demand and
simultaneously allows the mobile network to take advantage of
the highest possible centralization of mobile network functions
by leveraging flexible functional split adaptively compliant to the
current optical traffic demand.[+][-]
