Fujitsu implements global open of world’s first AI utility to prevent quality degradation in 5G wi-fi networks
KAWASAKI, Japan, Oct 15, 2024 – (JCN Newswire) – Fujitsu this day offered the pattern of an utility that leverages AI technology to enhance mobile community communication quality, while achieving vitality savings and optimizing community operations. This pattern is fragment of the Be taught and Building Mission of the Enhanced Infrastructures for Post-5G Recordsdata and Dialog Systems (hereafter NEDO-led project) (1) conducted by the Recent Vitality and Industrial Expertise Building Organization (NEDO). Fujitsu, which has a winning be aware yarn of introducing radio unit (RU) products to the worldwide market, will incorporate this technology into its O-RAN (2) compliant Carrier Administration and Orchestration (SMO) (3) system, FUJITSU Community Virtuora Carrier Administration and Orchestration. Fujitsu will implement a unimaginative global rollout of the technology to mobile community operators initiating in November 2024 by leveraging the footprint it has already cultivated in RU.
This utility contains three key applied sciences:An AI-powered technology that can possibly possibly estimate smartphone users’ quality of trip (QoE) on their networks in true time.A technology that detects early indicators of increased communication traffic and proactively prevents community quality degradation.A technology that detects community quality degradation and redefines the position covered by peripheral imperfect stations to contend with optimum quality.
Fujitsu verified the effectiveness of these applied sciences in August 2024 utilizing true business information from mobile community operators (4) below conditions closely equivalent to exact operating environments.
This utility shall be dash a seamless and legit connection for mobile community users, no longer most productive all by map of similar outdated operations however furthermore all by map of emergencies and sessions of increased community traffic, ultimately enhancing user convenience, satisfaction, and safety in principal eventualities. For mobile community operators, the utility will decrease operational prices and place energy by map of optimized operations.
Background
As digital transformation (DX) speeds up globally, the adoption of 5G mobile networks is fleet expanding as a key infrastructure ingredient. Cellular community operators are expected to additional enhance their capabilities, at the side of ultra-low latency and simultaneous connectivity, while ensuring community quality at user and utility ranges. Furthermore, the RAN (Radio Entry Community) arena is present process originate and virtualized transformation in step with the O-RAN principle, resulting in anticipated reductions in total designate of ownership (TCO).
The three applied sciences on this utility feature on the RIC (5) deployed all by map of the O-RAN compliant SMO, contributing to the incandescent automation and self-sufficiency of RAN.
Building achievements1. Staunch-time QoE estimation and quality assurance utilizing AI
This technology estimates QoE in true-time and robotically switches users to other imperfect position community areas when QoE degradation is detected. It is a world-first, enabling the introduction of AI objects that can possibly possibly simply estimate QoE for individual purposes by deciding on feature values from statistical information (KPIs) calculated from excessive-tempo packet analysis for 100 Gbps RAN traffic. This reach permits for flexible adaptation to numerous purposes.
By precisely working out the QoE of every user and assigning the an principal sources, this technology ensures user convenience and satisfaction while concurrently suppressing excessive useful resource allocation. This outcomes in a 19% originate bigger in the different of users that would also be accommodated per imperfect position (6).

Fujitsu has developed a technology that makes use of AI to discontinuance wide awake for increased communication traffic and proactively set off beforehand dormant imperfect stations to prevent degradation in user communication quality.
Previously, vitality savings hold been finished by monitoring traffic in every position in true-time and hanging pointless imperfect stations into sleep mode. This world first technology goes a step additional by detecting odd will enhance in pedestrian traffic, equivalent to those connected with local occasions, and predicting subsequent traffic will enhance on the grid level (7). This predictive technology has been proven to efficiently set off imperfect stations upfront without impacting user quality Ninety nine.8% of the time all by map of the verification length.
This enables pinpoint activation and deactivation of imperfect stations in step with traffic conditions, achieving a stability between hanging forward QoE and saving vitality when blended with the vitality-saving utility offered by Fujitsu in December 2023 (8).
3. Detection of carrier quality degradation and position redesign for carrier quality repairs
Primitive anomaly detection applied sciences for single cells (9) struggled to distinguish between easy load reductions and exact anomalies. Fujitsu’s fresh technology addresses this by comparing traffic traits all by map of surrounding cells utilizing AI, achieving a fault detection accuracy fee of over 92%. This technology helps both supervised discovering out with dinky fault information as successfully as unsupervised discovering out. By working out the carrier impact at the side of cell overlap, it’s miles feasible to originate a judgement on which areas must be recovered first.
When this anomaly detection technology identifies areas present process important carrier impact, it makes use of a radio propagation prediction mannequin that considers course loss (10) in the true field, as successfully as to the route and load conditions of surrounding cells, to calculate the optimum tilt attitude for surrounding cells. This minimizes the impact on carrier quality precipitated by wicked cells. Due to this, recovery time from anomalies equivalent to tools failure, which beforehand took 24 hours, has been lowered to lower than one hour, minimizing the impact on users.

Future Plans
Fujitsu will proceed to make a contribution to the realization of a safer, extra stable, and sustainable society by providing O-RAN products utilizing AI-centric applied sciences for networks that toughen purposes and services and products all by map of industries.
