O-RAN based multi-vendor connectivity test results show over 20% energy savings
Fujitsu Limited
December 19, 2023 Tokyo
Fujitsu today announced the successful implementation of Virtuora Service Management and Orchestration (SMO). (1) Products for Open RAN with power saving applications (2) Utilizes AI technology developed by Fujitsu. Fujitsu rApp uses machine learning and artificial intelligence-powered traffic estimation to turn network capacity on and off as needed while maintaining service continuity. Fujitsu conducted interoperability tests of Virtuora SMO products equipped with RAN equipment in November 2023, and confirmed power savings of more than 20% compared to the conventional method of estimating communication traffic for each base station.
In addition, we successfully tested interoperability with a third-party system-level RAN emulator that complies with the O-RAN specification provided by VIAVI Solutions (VIAVI, an American telecommunications network measurement equipment vendor). VIAVI TeraVM RIC Test is a comprehensive AI training enablement, test and measurement solution for Open RAN RIC, xApps validation. (3) and rApp (Four) Use a containerized platform.
Fujitsu announces test results at “O-RAN ALLIANCE Global PlugFest” (Five) International event “Fall 2023” hosted by Oran Alliance (6) O-RAN ALLIANCE will be publishing a PlugFest virtual showcase that will provide more detailed information.
Going forward, Fujitsu plans to build and strengthen a global, multi-vendor Open RAN ecosystem. Fujitsu will help telecommunications carriers reduce operation and maintenance costs and accelerate the development of new services, and will contribute to the realization of carbon neutral network operations through power-saving technology.
Connection test overview
1. Date:
November 17, 2023
2. Location:
COSMOS Lab at Rutgers University, New Jersey, USA (one of two open test and integration centers in North America and hosting part of the O-RAN ALLIANCE Global PlugFest Fall 2023)
3. Exam overview:
- Conducted interoperability testing, including multi-vendor end-to-end connectivity and interoperability validation. (7)between Fujitsu’s Virtuora SMO products and VIAVI’s verification equipment, according to specifications established by the O-RAN ALLIANCE (O-RAN Specifications)
- Conducted power consumption test of Virtuora SMO equipped with power saving application (rApp).Fujitsu has confirmed power savings of over 20% compared to conventional methods
4. Contents, roles and responsibilities:
As part of the interoperability test, Fujitsu has built a test facility consisting of Fujitsu’s Virtuora SMO product, which is equipped with the Virtuora Mobility Controller, an integrated RAN control function that enables parallel use of power-saving applications, and Closed RAN. (8)/Open RAN, multi-RAT (9)and the RIC test “TeraVM RIC test” (Ten) A tester that simulates RAN functions developed by VIAVI.
responsibility:
Fujitsu: Multi-vendor connectivity evaluation
Viavi: RAN scenario generation, power saving analysis and monitoring
Companies such as AT&T Communications participated in the test as advisors, and examined test items from the operator’s and operational perspectives. Interoperability testing was conducted under review by AT&T.
Multi-vendor interoperability testing has confirmed that Fujitsu’s Virtuora SMO can connect to RAN equipment from third-party vendors and achieve power savings.
Figure 1: Overview of interconnection test5. Fujitsu’s communication volume estimation AI technology used in power-saving applications
- Utilizes time-series prediction technology to predict communication volume in a small area of about 100 square meters based on time-series location distribution data of users and devices.
- Combining optimization technologies to quickly select the RU configuration that provides the best power savings at any given time
By harnessing the power of AI, Fujitsu’s innovative application accurately estimated communication traffic for individual base stations on a cell-by-cell basis. This AI-driven approach saved more than 20% power compared to traditional methods, impacting areas ranging from a few square kilometers to hundreds of square meters.
