Samsung Electronics has developed next-generation technology that proactively prevents smartphone communication dropouts using artificial intelligence (AI). When applied to an actual communications network, the frequency of quality degradation was reduced by nearly half. Based on this, Samsung Electronics plans to secure technological leadership in the upcoming sixth-generation mobile communication (6G) era.

On the 10th, Samsung Electronics announced that it had completed a simulation of an AI wireless network (AI-RAN)-based “user-customized communication quality optimization technology” in collaboration with Japanese mobile operator NTT DOCOMO. This technology automatically changes network settings such as frequency bands, tailored to individual users, when a decline in communication speed is anticipated, thereby preventing disconnection. For example, before buffering occurs while watching a video on a smartphone, AI autonomously optimizes the communication environment.

The two companies implemented the new technology through AI-RAN, which controls the network by applying AI to the radio access network, including base stations. Conventional communication networks applied the same settings uniformly to all devices connected to a single base station, making them vulnerable to changes in the radio environment. In contrast, AI-RAN preemptively blocks signs of communication quality degradation by having AI learn users’ movement paths and data usage patterns in advance.

The effect has been demonstrated in figures. Using data from commercial networks and 5G test networks in Japan this January, the two companies ran simulations that showed the occurrence rate of data transmission speed decline decreased from 13.1% to 7.2%.
A process that minimizes network load was also developed. Previously, network load was high because radio environment information had to be collected and processed in bulk, but the new process prevents overload by selectively processing only the key information required for each situation.

Jung Jin-kook, Head of Next Generation Communication Research Center at Samsung Research, Samsung Electronics (Executive Vice President), said, “This verification has empirically demonstrated AI’s effectiveness in improving communication quality,” adding, “Samsung will continue to collaborate with NTT DOCOMO to lead future communication technologies such as 6G.”
