The full potential of the software networks is now beginning to take shape especially with the development of the 5G service-based architecture, the wide adoption of the edge deployments as a means to serve an optimized connectivity and the liberalization of the spectrum towards enabling the deployment of private, dedicated 5G networks.
This tutorial will address, in a coherent manner across the different domains, the flexibility and automation topic. After setting down the possible benefits of flexibility and its automation, a detailed impact on the different areas of the 5G system is provided including: radio technologies and spectrum allocation, edge and core network system deployments, backhaul and application integration. Following, an assessment of the 5G standards evolution is presented, especially concentrating on the opportunities arising beyond 3GPP Release 15 and the functionality existing and still required to support ultra-low latency and high reliability, low-cost and large coverage as well as mobile broadband scenarios.
Additionally, the tutorial will include a comprehensive overview of management functions that can be deployed together with the 5G system, especially concentrating on the automation of the management services, the implications of pushing functionality towards the edge of the network as well as on the impact of advanced data processing, and artificial intelligence can provide for a highly optimized network system.
The tutorial concludes with the outlining on how the flexibility and automation can be brought, in a relevant manner, to 5G research and especially product development implemented as part of the Fraunhofer FOKUS software tools and within the 5G Playground. The tutorial will cover the following topics:
- Understanding the flexibility and automation brought by the software revolution
- 5G system standardization advancements
- Impact of flexibility towards the 5G system
- Network management and intelligence for 5G systems
- Best practice developments of software networks toward 5G trials
