5G mobile networks are characterised by the goal to host a large diversity of use cases that enable ubiquitous communication through new services in e.g. industrial, media & entertainment (M&E), smart city, vehicular, or public safety scenarios. 5G has to satisfy differing requirements on e.g. network performance, reliability, or security, together with cost, and thus requires a flexible and adaptable network architecture as well as functional features that enable the implementation of specific use cases.
These challenges have been addressed by 5G-MoNArch, through its ultimate goal to create a 5G system that is actually usable in practice and proving its feasibility and applicability in real-world environments. The objectives have thereby been to: i) provide a detailed and fully-fledged 5G mobile network architecture design together with key innovations enabling the operation of 5G network slicing (i.e. logical isolated network sharing a common infrastructure); ii) develop features required to implement two verticals-defined use cases (industrial and M&E); iii) deploy and implement the architecture, use cases, innovations and technologies in real-world testbeds; and to iv) evaluate, verify and validate the developed solutions on their technical and economic performance. The overall project approach is shown in Fig. 1.
The 5G-MoNArch goals and objectives have been fully achieved. Based on the requirements and use cases of directly involved verticals, a flexible and adaptive network architecture framework that allows to fully integrate features for industrial, M&E, and smart city applications (and beyond) has been developed. The applicability of this framework and the developed features for reliability, resilience, security and resource elasticity in real-world environments has been showcased and proven with the Hamburg Smart Sea Port and Turin Touristic City testbeds and the simulation-based verification. The socio-economic verification has gone beyond this technical feasibility and highlighted the economic advances of the developed solutions, which has been finally validated through stakeholders.
