(Headquarters: Tokyo; President and CEO: Akira Shimada; hereinafter "NTT"), and NEC Corporation (Headquarters: Tokyo; President and CEO Takayuki Morita; hereinafter "NEC") have integrated three newly proposed technologies on a 6G(*1)/IOWN(*2) platform to realize the widespread use of AI agents(*3) supporting a safer and more secure society. Through this initiative, the three parties have combined streaming semantic communication technology(*4), AI-oriented media control technology(*5), and In-Network Computing (INC) architecture technology(*6) to optimize the high-volume data transmission and computational processing required for AI agents. The effectiveness of these technologies has been quantitatively verified through a trial, and plans are slated for this initiative to be showcased at the Mobile World Congress 2026 (MWC 2026) Japan Pavilion, where the research findings and underlying concept will be presented to an international audience.Figure 1. Overview of the technologies integrated on the 6G/IOWN platform1. Background and significance of this three-party collaborationInternational collaboration and global standardization are vital to the advancement of telecommunications, which serves as a universal platform accessible to anyone, anywhere in the world, and should therefore be considered from a global value perspective. In recent years, the importance of safety and security has grown, as both offer global value.To realize a safer and more secure society, the ability to quickly perceive and take appropriate action in response to disasters, accidents, cyberattacks, and other rapidly evolving situations is imperative. However, relying solely on personnel and predefined rules to respond to such situations has its limitations, making the use of AI essential. Utilizing AI agents enables autonomous, real-time perception of the situation at hand, helping to prevent potential damage and minimize the impact of any damage that does occur.Meanwhile, next-generation ICT infrastructure capable of processing and transmitting massive amounts of data with low latency and high reliability is vital to enhancing the functionality of AI agents.Against this backdrop, The University of Tokyo, NTT, and NEC—all three of which possess strengths in 6G and IOWN—have united under The University of Tokyo’s Social Cooperation Program to conduct research and development on 6G and IOWN platform technologies to realize AI agents supporting safety and security.2. Research backgroundWhile the use of AI in recent years has primarily centered on models that act based on human prompts, the utilization of AI agents capable of acting autonomously based on sensor data and other non-human-originated inputs without relying on specific instructions from human operators is expected to become increasingly common in the society of the future. In turn, these advancements will enable the realization of AI agents that support safety and security by continuously collecting and monitoring data from the surrounding environment and responding in real time when signs of abnormalities are detected.However, the expanded use of continuously operating AI agents will cause the amount of multimodal data(*7) to skyrocket, and existing ICT infrastructure is not equipped to support such a drastic increase in data due to the technological challenges listed below.(1) Insufficient wireless bandwidthContinuous transmission of vast amounts of data from countless sensors and devices makes it difficult to secure sufficient wireless bandwidth.(2) Increasing computational load due to round-the-clock AI processing of sensor dataIf all sensor data is continuously processed using computationally intensive AI, it will cause an excessive computational load, making it difficult to respond in real time.(3) Increasing computational load and power consumption with large-scale AILarge-scale AI is required to analyze a wide range of sensor data, thereby increasing the need for computational capabilities and electrical power.3. Technology highlightsIn this research, the three parties proposed the following technological approaches to resolve the aforementioned challenges.(1) Streaming semantic communication technology (The University of Tokyo)This applied form of semantic communication detects contextual changes and transmits only semantic differences, thereby reducing wireless communication resources dramatically.(2) AI-oriented media control technology (NEC)Assigning a data identifier to an AI agent and then selectively feeding only key sensor data to the AI agent reduces the computational resources required for inference. Learning inference results from the AI agent, the data identifier is able to identify critical sensor data.(3) In-Network Computing (INC) architecture technology (NTT)Rather than relying on a single massive AI model, highly efficient and reliable AI processing is made possible by combining small, specialized AI distributed across the network with external information sources.Figure 2. Technological challenges and the proposed approach4. Trial OverviewThis trial was conducted to verify the impact of the proposed technologies in terms of reducing latency through the improvement of transmission and computational processing efficiency, taking into account the characteristics of end-to-end latency(*8) (E2E latency) when using AI agents. In this trial, a video dataset including critical situations (60 seconds; 1,800 frames) was used to conduct a phase-by-phase evaluation of the configuration with which an AI agent processes video input from sensors. The intended use cases are scenarios requiring real-time performance where an AI agent continuously monitors the surroundings of a user wearing augmented reality (AR) glasses to identify environmental and contextual changes that can be used to predict and assess risk indicators.First, the latency characteristics in a configuration where all frames fed from a sensor were sequentially processed using AI were assessed as a preliminary evaluation. The results confirmed that processing wait time increases cumulatively with each frame, resulting in a tendency for E2E latency to build over time. This implies an increase in the amount of time it takes from the occurrence of a critical situation in front of the user until assessment results and guidance are provided, thus revealing that this could pose an issue in use cases involving real-time AR assistance.Next, on the basis of the results of the preliminary evaluation, a system configuration was assessed in which the proposed technology was applied in this trial. The evaluation confirmed that both communication traffic and computational load were reduced, and that E2E latency could be maintained at an almost constant level throughout the entire video stream. In addition, no tendency was observed for processing wait times to increase cumulatively. Furthermore, no degradation in AI inference accuracy was detected as a result of applying the proposed technology. These results demonstrate that, for this use case, which requires real-time performance, the proposed technology can stably reduce E2E latency while maintaining AI inference accuracy. Figure 3.1.
