On February 7th, the highly anticipated 9th Asian Winter Games 2025 kicked off in Harbin, Heilongjiang Province. This is another major comprehensive international ice and snow sports event hosted by China after the 2022 Beijing Winter Olympics. Since the first use of satellite communication technology for live television broadcasting at the 1964 Tokyo Olympics, major sports events have always had technological highlights. Now, as this year's Asian Winter Games welcomes the wave of the 6G era, it is the first time that cutting-edge technologies such as metaverse, digital twins, and cloud management have been integrated into international sports events, bringing unprecedented intelligent experiences to the audience. As a crucial link in the hosting and dissemination of sports events, information and communication services play a pivotal role in the Harbin Asian Winter Games. This year's Asian Winter Games deployed advanced 5G-A networks, and the upgrade of this network technology has become a solid foundation for the smooth application of various new technologies. 5G-A network can be understood as 5.5G. Compared to 5G networks, it has larger bandwidth, shorter latency, and a wider range of connections Wang Chuanbao, Secretary of the Party Committee and General Manager of China Unicom Heilongjiang Branch, introduced it. The Yabuli Snow Training Center is the venue for the snow events of this year's Asian Winter Games. On the large screen of the venue command center, the 3D digital twin system of the entire competition area is clearly displayed. The system provides a panoramic restoration of the venue, computer room, and equipment information of the snow competition area, allowing managers to experience it firsthand through cloud tourism, greatly improving management efficiency. Tang Yuxiang, the communication supervisor of China Unicom in the Yabuli competition area, introduced that relying on the network indicators of the digital twin system, managers can also monitor the real-time operation of the competition area network, cooperate with professional network administrators to fully ensure the safe operation of the communication network, and provide stable and efficient network experience for officials and athletes in the competition area. In terms of network security, cloud computing, big data, and big model technologies ensure smooth network connectivity for this year's Asian Winter Games. In the communication security room, the digital monitoring system of the smart room is eye-catching. The system is capable of AI intelligent control over venue data centers and core data centers, as well as detecting hazards and alerting and identifying personnel entering and exiting the data centers, ensuring the smooth progress of the event. In the past, mobile networks may have experienced network instability at the coverage edge. But with the use of intelligent 3CC technology, we can perform targeted intelligent fine-tuning to ensure that the same experience as the network center can be achieved at the edge of the network Ji Yanqi, an expert from the Science and Technology Innovation Department of China Unicom Heilongjiang Branch, said. In addition, intelligent technology has also played an important role in network security. Security robots and security GPT technology can not only automatically patrol and inspect the network, detect security vulnerabilities in real time, but also trace and investigate attacks or malicious behavior, providing strong protection for the network security of events. At the main media center, reporters not only experienced the high-speed network, but also experienced the convenience of cloud editing. Wang Chuanbao introduced that China Unicom has created a media broadcasting cloud for this year's Asian Winter Games. Media practitioners can conduct live broadcasts, editing, and forwarding of events on the cloud, greatly reducing the cost of event broadcasting. Cloud broadcasting technology can allow TV program producers to 'stay at home'. For example, in the editing rooms of foreign media, image materials collected during the Harbin Asian Winter Games can be directly edited and processed. On this basis, simply adding playback effect processing can directly play it locally Wang Chuanbao said. In the past, media broadcasts of large-scale sports events often used fixed camera positions to collect image information at different locations. This approach may miss many details. And this year's Asian Winter Games deployed a series of networks that are convenient for real-time, on-site, and blind spot signal collection through wireless technology. The camera can capture and transmit live footage in real-time from any position. For example, when descending from a high mountain, if an athlete wears a camera on their head, the audience can experience the thrill of speeding from the athlete's perspective. This year's Asian Winter Games also created a dedicated media transmission network in the field of fixed broadband. Wang Chuanbao introduced, "The 2022 Beijing Winter Olympics will use IPV6+1.0 technology. Now, this technology has been upgraded to IPV6+3.0, and we have achieved the first international deployment and application. In addition, China Unicom will apply artificial intelligence to this technology, making network scheduling and management more intelligent and refined
