Deploying Smart City components for 5G network slicing

The integration requirements between digital systems acting as enablers for vertical industries services and network layers represents a big challenge for multitenant vertical slice deployment initiatives over 5G infrastructure. Several concepts were developed, among them Smart City 5G-ready application based on cloud-native/microservice principles that proposes a separation between the orchestration of the 5G applications and the network services that support them. In this paper we are presenting the deployment phases of Smart City demonstrator focusing mainly on its first phase which covers the test bed deployment and the on-boarding process of application components. It is an advanced stage in the evolution of the project from the theoretical concept proposal [1], followed by the design and development phase as a collaboration between two 5G-PPP EU projects MATILDA and SliceNet [2] toward its completion as an automated solution for development, deployment and management of a Smart City 5G cloud-native application slice over the virtualized infrastructure. The target is to create and implement an end-to-end operational service framework starting from design and development to end to end orchestration over a 5G infrastructure through a One-Stop API assuring the end-to-end management, control and orchestration of the slice.
