5G Network Architecture, Functional Model and Business Role for 5G Smart City Use Case: Mobile Operator Perspective

Presently, the most challenging activity for mobile operators, equipment vendors and telecom researchers is the study of 5G networks. A major step in implementing such a network is to design an architecture capable of meeting all the challenging requirements, to create interoperability with the existing networks and to be able to accommodate all new services and use cases. Our main contribution in this paper is the realization of a general architecture for a 5G network, from the mobile operator perspective. We have described the entities involved in this architecture with emphasis on virtualization and resource management part. We are proposing that the first deployable scenario under our 5G network will be Smart City, developed in H2 2018. That's why the paper presents also the main features of a 5G Smart City and describes a particular solution that will be developed within this city, Smart Lighting. In addition we have also synthesized, from the proposed architecture, a perspective of the functional model and business role for Smart Lighting use case, that is very important to us.
