Initiatives toward Open RAN▼Abstract

The fifth-generation mobile communications system (5G)
network will need to support a wide range of services comparedwith past networks. To meet this need, it will be necessary toconstruct a flexible network that can accommodate all types ofservices. The Open Radio Access Network (RAN) can makethis a reality. This article provides an overview of Open RAN,
presents the current state of the O-RAN ALLIANCE that
promotes Open RAN standards, and describes the 5G OpenRAN Ecosystem, a new NTT DOCOMO Open RAN initiative.
