Fujitsu has developed an application that uses AI to improve the communication quality of mobile networks while saving power.

The company will install the application in its O-RAN-based operation management system (SMO) “FUJITSU Network Virtuora Service Management and Orchestration” and roll it out globally to mobile network operators around the world from November.

The application is composed of three technologies: technology to estimate network quality in real time using AI and maintain quality, technology to prevent network quality degradation during events, and technology to redesign base station coverage areas to maintain quality. The effectiveness of the three technologies has been confirmed through testing under conditions similar to the operational environment.

The application will provide the “ease of connection” that mobile network users expect most not only in normal times but also during emergencies such as natural disasters and events, leading to improved convenience and satisfaction and ensuring safety in emergencies.

The company has developed technology that estimates QoE in real time and automatically switches to the network area of ​​another base station when a decrease in QoE is detected. This is the world’s first technology that calculates statistical data (KPIs) for each user and application from high-speed packet analysis compatible with 100 Gbps RAN traffic, and generates an AI model that easily estimates the QoE for each application simply by selecting features from the KPIs, allowing it to flexibly handle a variety of applications.
This ensures convenience and satisfaction by accurately grasping the QoE of each individual user and allocating the necessary resources.
