Abstract
There is provided an Open Radio Access Network (O-RAN) that includes a fronthaul interface over which an O-RAN Distributed Unit (O-DU) and an O-RAN Radio Unit (O-RU) communicate with one another and exchange O-RAN standard defined user-plane (U-plane) packets and control-place (C-Plane) packets. The fronthaul interface carries control and management information via management-plane (M-Plane) message exchange, and timing synchronization is achieved in accordance with synchronization-plane (S-Plane) procedures, and the O-RAN accommodates communications via 2G and 3G based mobile networks.
