Overview

Background

Since the Great East Japan Earthquake, efforts have been made to strengthen the disaster resistance of ICT and to predict the scale of damage caused by disasters. In the Beyond 5G era, we will be transformed into a Society 5.0 society where cyber space and physical space are closely linked. In order to maintain this society, it is essential to realize a green and resilient B5G network that enables decarbonization, in addition to preparing for huge natural disasters such as the Nankai Trough. The results of this research and development will contribute to the effective use of radio waves by promoting the efficient use of radio waves in the RAN through the control of radio resources in the RAN during normal times and disasters, as well as by strengthening the resilience and greening of Beyond 5G.

Purpose

Realization of vRAN in green and resilient B5G networks with adaptive control of network resources including power.During normal times, the Radio Access Network (RAN) of the Beyond 5G Network (NW) will be operated as much as possible with independent power sources using renewable energy and storage batteries, and in the event of a disaster, the RAN that survives with independent power sources will be able to secure communications through adaptive control of NW resources, including power. In the event of a disaster, we will realize a green and resilient vRAN (virtual RAN) that secures communications through adaptive control of NW resources, including power, for RANs that survive due to independent power sources. Specifically, we will conduct research and development of adaptive control of cell configuration in B5G RANs according to disasters, based on the premise of virtualized NW architecture with SDN and NFV.
