Samsung, Docomo Verify AI-RAN Network Optimization
Before a user watching a video enters an area with weak signal strength, artificial intelligence predicts the degradation in quality in advance and alters the network settings. This is the core of the ‘user-customized communication quality optimization’ technology implemented by Samsung Electronics
Samsung Electronics and Japanese mobile carrier NTT Docomo have jointly verified a new AI-RAN technology designed to optimize network settings for individual users. This AI-based system predicts signal degradation before it occurs and adjusts network configurations accordingly, marking a significant shift from the traditional approach of uniformly applying settings across all connected devices.
The core of this 'user-customized communication quality optimization' technology is the use of artificial intelligence to analyze user-specific service usage patterns and the real-time wireless environment. By learning these patterns, AI can anticipate when factors like buffering might occur, such as during video streaming, and proactively select the optimal frequency band to maintain high-definition video quality.
In January, Samsung and Docomo conducted simulations using data from Docomo's commercial network and local 5G test networks. Following this verification, the frequency of service transmission speed degradation dropped from 13.1% to 7.2%. Additionally, a new data processing process was developed to enhance operational efficiency, ensuring that only necessary information is processed for each specific problem situation, thereby reducing the burden on the network.
Samsung and Docomo submitted this new procedure to the global mobile communication standardization organization, 3GPP, in February, aiming to secure technological leadership. Jeong Jin-guk, Executive Vice President and Head of Samsung Research's Advanced Communications Research Center, expressed satisfaction with the achievement, stating, "We have proven that AI can substantially improve the service experience of individual users."
He also indicated a commitment to further advancing AI-RAN technology and continued standardization cooperation. Masafumi Masuda, Head of the 6G Tech Department at NTT Docomo, agreed, calling this a significant step toward realizing a user-centric communication experience in future networks.
