Today, Fujitsu announced that it has successfully integrated a power-saving application (2) employing AI technology created by Fujitsu into its Virtuora Service Management and Orchestration (SMO) (1) service for Open RAN. The Fujitsu rApp maintains service continuity by adjusting network capacity on- and off-demand using traffic estimations driven by artificial intelligence and machine learning. In November 2023, Fujitsu tested the Virtuora SMO solution with RAN equipment for interoperability. The testing verified power savings of about 20% as compared to traditional techniques for predicting communication traffic for individual base stations.
Fujitsu also successfully completed interoperability testing using a third-party, O-RAN-compliant system-level RAN emulator that was supplied by VIAVI Solutions, an American provider of telecom network measuring equipment (henceforth VIAVI). With a containerized platform, VIAVI TeraVM RIC Test offers an all-inclusive AI training enablement, test, and measurement solution for the validation of Open RAN RIC, xApps (3), and rApps (4).
At the “O-RAN ALLIANCE Global PlugFest (5) Fall 2023,” an international gathering hosted by the O-RAN ALLIANCE (6) in November 2023, Fujitsu revealed the test results. To provide further information, O-RAN ALLIANCE intends to release a virtual showcase at PlugFest.
Fujitsu intends to further the development and improvement of an Open RAN ecosystem with several vendors on a global scale in the future. With power-saving technology, Fujitsu hopes to help telecommunication carriers realize carbon-neutral network operations by lowering operating and maintenance costs and speeding up the development of new services.
