The work which beings this month is part of the 5GPPP standards process. It will define the network architecture incorporating the radio access network (RAN) and core network, teh work is dubbed 5G NORMA (5G Novel Radio Multi-service adaptive network Architecture).
The 5G network architecture will be fundamentally different from the 4G architecture. Defining the architecture will be one of the biggest challenges for 5G development. As a result the work is expected to take 30 months.
Dr. Werner Mohr, chairman of the 5GPPP Association, said:
“5G is not only about new radio access technology — network architecture will play an important role as well. 5G networks will have to be programmable, software driven and managed holistically to enable a diverse range of services in a profitable way.”
The proposed 5G network will dynamically adapt network resources to meet traffic and service demands which will change over time and with location.
The technical approach is based on the innovative concept of adaptive (de)composition and allocation of network functions, which flexibly decomposes the network functions and places the resulting functions in the most appropriate location.
One new characteristic of the 5G network will be that access and core network nodes will no longer be in different locations, but combined in intelligent ‘super’ nodes
The network infrastructure will make use of software-defined network configuration.
Also for the first time in the mobile standards process socioeconomic analysis of the network architecture will also be conducted. The hope is to better understand the value to users as well as the operators.
“With 5G NORMA, the consortium aims to ensure economic sustainability of the network operation and open opportunities for new players, while leveraging a futureproof architecture in a cost- and energy-effective way,” said Mohr.
Full list of companies and universities in the consortium
- Vendors and IT: Alcatel-Lucent, NEC, Nokia Networks, ATOS
- Operators: Deutsche Telekom, Orange, Telefonica
- Small to medium-sized enterprises: Azcom Technology, Nomor Research, Real Wireless
- Academia: University Kaiserslautern in Germany, Kings College London, University Carlos III Madrid
Real Wireless will carry out a socioeconomic assessment of the proposed network architecture. This will include identifying market drivers in a range of industries from public safety (PPDR), to transportation, energy generation and distribution.
Its work will also assess shortcomings in the expected capabilities of 4G LTE by 2020, based on the requirements of the expected future service demands.
Professor Simon Saunders, director of technology at Real Wireless, said:
“Our work will bridge the technical, social and commercial domains, enabling the consortium to identify the relative value of each planned 5G NORMA innovation.”
