Management of Mission Critical Public Safety Applications: the 5G ESSENCE Project

To address the limitations of legacy Public Safety (PS) solutions, as narrow bandwidth, high deployment cost and poor flexibility, the 5G cellular systems have been proposed. The architecture proposed by the 5G ESSENCE project is based on a cloud-enabled small cell infrastructure with a fully distributed orchestration architecture leveraging multi-access technologies in 5G. Furthermore, SDN and NFV are exploited, with MEC, to create flexible slices for dedicated mission critical public safety applications also at the edge of the network. This is shown by describing as the mission critical push-to-talk services have been implemented in a real testbed.
