This paper focuses on energy efficiency aspects and related benefits of RAN-as-a-Service (RANaaS) implementation (using commodity hardware) as architectural evolution of LTE-Advanced networks toward 5G infrastructure. RANaaS is a novel concept introduced recently, which enables the partial centralization of Radio Access Network (RAN) functionalities(More)
As a chain is as strong as its weakest element, so are the efficiency, flexibility, and robustness of a mobile network, which relies on a range of different functional elements and mechanisms. Indeed, the mobile network architecture needs particular attention when discussing the evolution of 3GPP EPS because it is the architecture that integrates the many(More)
A novel autonomic area reconfiguration mechanism is proposed to manage the hierarchical arrangement of routing protocols in wireless access networks. The reconfiguration mechanism monitors the traffic and mobility patterns to identify symptoms, which indicate a poor existing area partition. A re-partition algorithm is invoked on demand with the objective to(More)
The ever-increasing traffic demand is pushing network operators to find new cost-efficient solutions towards the deployment of future 5G mobile networks. The network sharing paradigm was explored in the past and partially deployed. Nowadays, advanced mobile network multi-tenancy approaches are increasingly gaining momentum paving the way towards further(More)
