SESAME targets innovations around three central elements in 5G: the placement of network intelligence and applications in the network edge through NFV and Edge Cloud Computing; the substantial evolution of the Small Cell concept which is already mainstream in 4G but it is expected to deliver its full potential in the challenging high dense 5G scenarios, and the consolidation of multi-tenancy in communications infrastructures, allowing several operators/service providers to engage in new sharing models of both access capacity and edge computing capabilities. To that end, SESAME proposes the Cloud-Enabled Small Cell (CESC) concept, a new multi-operator enabled Small Cell that integrates a virtualised execution platform (i.e., the Light DC) for deploying VNFs and executing novel applications and services inside the access network infrastructure. This approach allows new stakeholders to dynamically enter the value chain by acting as ‘host-neutral’ providers in high traffic areas where densification of multiple networks is not practical. Also, the optimal management of a CESCs is a key challenge of SESAME, for which new orchestration, NFV management, virtualisation of management views per tenant, Self-x features and radio access management techniques are being developed.
