1

The beijing 2022 Winter Olympic and Paralympic Winter Games are in full swing, and the scientific and technological forces inside and outside the arena have produced a "spillover effect", and a new "spark" has been rubbed with all walks of life.

From the "100-meter-level, minute-level" accurate weather forecast to the construction of 5G smart venues, from network security to ultra-high-definition video live broadcasting, from cloud broadcast technology to smart services, all of them highlight the host's meticulous humanistic care and reflect the temperature of China's "high-tech" technology.

Behind this, it is inseparable from the builders of many "smart Winter Olympics", including ICT manufacturers who have paid silently, such as China Unicom, China Telecom, China Mobile, China Tower, Huawei, Ericsson, Intel, iFLYTEK, Qianxin, Alibaba Cloud, Gehua Cable, Digital Video, Qianxun Location, etc. Huawei provided industry-leading 5G outdoor macro base stations, indoor micro-base stations, transmission equipment, and 5G core networks for the communication construction of winter Olympic venues, and iFLYTEK provided automatic translation and related hard-core technologies such as speech conversion, speech recognition, and speech synthesis for the event, helping to achieve barrier-free communication between inside and outside the Beijing 2022 Winter Olympic and Paralympic Winter Games.

Ericsson: 2.6GHz + 4.9GHz carrier aggregation, making the network faster, more stable and stronger

As a high-profile international event, the network of the Winter Olympic games needs to meet high levels of uplink and downlink speeds and ensure the smooth operation of the network. At the same time, sharing the wonderful Winter Olympic moments in real time is an indispensable experience for watching the games in the cloud, and it is also a new test for enterprises and communication engineers.

During the test match, in order to meet the 5G communication service needs of all the mobile phones in the venue, as well as the "high-density heavy load" scenario requirements of 5G+4K/8K ultra-high-definition cloud broadcasting, Ericsson and Hebei Mobile jointly discussed and adopted the "2.6GHz + 4.9GHz carrier aggregation function", which can integrate and reuse the network in the hot spots in the core competition area of Zhangjiakou, increase the downlink peak rate to more than 3Gbit/s, and double the network throughput rate.

Such a rate level not only meets the network transmission needs of various high-definition live broadcast applications, but also makes full use of existing carrier resources to meet the network usage needs of live audiences, avoiding the problem of smooth broadcasting of live games or congestion due to high capacity. While improving the user experience, it also brings new choices to the organizing committee's event broadcast plan.

In addition, in view of the particularity of the communication network guarantee in the competition area, Ericsson and Hebei Mobile conducted in-depth discussions on the needs of "efficient operation and maintenance" and developed a customized "intelligent network optimization platform". The service platform is designed to improve the diagnostic speed of network performance, with high scalability and good results. By using big data, artificial intelligence and data analysis functions, the platform implements real-time monitoring of many network performance indicators, which provides an effective guarantee for improving network operation and maintenance efficiency.

The service platform can not only realize the automation and real-time monitoring and push of real-time indicators by scenario, but also automatically verify parameter configuration and intelligently analyze network performance-related issues such as interference, capacity and load, providing accurate, automatic and real-time performance monitoring for the mobile network in the Zhangjiakou event area, and providing comprehensive, graphical and geographical intelligent analysis for different scenarios, so that spectators can obtain a good network experience.

Alibaba Cloud: The core information system of the Winter Olympics has achieved 100% cloud migration

Beijing presented an innovative Olympic event to the world, and the widespread use of cloud technology in the Olympic sports scene simplified the development, integration and deployment process of the Olympic business system, shortening the time, reducing the cost and enriching the user experience.

"The Beijing Winter Olympics coincided with the Spring Festival holiday, so the attention increased sharply, and higher requirements were put forward for the resource scheduling, system stability and security of the network. Alibaba Cloud has made sufficient preparations in terms of re-guaranteeing the formation and emergency plan to fully ensure the smooth progress of the Winter Olympics," said the person in charge of technical support for the Alibaba Cloud Winter Olympics.

Among them, the Olympic core system refers to the digital information system that plays a key role in the organization and operation of the Olympic Games. With the continuous evolution of the Olympic organization and management model, the olympic core system is currently divided into three categories: one is the Olympic information management and distribution system (OMS/ODS), which provides the event schedule, athlete registration, registration, Olympic information release, etc.; the second is the Games management system (GMS), providing services for athletes' transportation, accommodation, arrival and departure, medical and health care; and the third is a series of digital platforms including event organization and collaborative office.

Yu Hong, director of the Technology Department of the Beijing Winter Olympics Organizing Committee, said that the core information system of the Beijing Winter Olympics has achieved 100% cloud, and the core information systems of the Olympic Games, event broadcasting, information release, athlete arrival and departure, medical care, accommodation, and transportation have been migrated to Alibaba Cloud. This is the first time in the history of the Olympic Games that cloud computing has replaced traditional IT, carrying the organization and operation of the Olympic Games, and cloud security is crucial.

The realization of the core system of the Beijing Winter Olympic Games is a milestone in the digitalization of the Olympic Games, which can not only efficiently integrate resources and support the operation of the event, but also bring a variety of viewing methods and a new viewing experience to sports fans, and also bring more production space to media workers, so that Olympic workers around the world can enjoy high-quality remote production on the cloud.

It is worth mentioning that in these technical solutions, the concept of "green Olympics" and sustainable development runs through the whole process. In 2018, the Beijing Winter Olympics Organizing Committee and Alibaba Cloud jointly unveiled the Beijing Winter Olympic Cloud Data Center, which was deployed in alibaba's Zhangbei data center, maximizing the use of local wind, solar energy and other clean energy sources, with the help of natural forces to achieve cooling, only about 15 days a year need to use the traditional cooling mode, energy consumption dropped by 59%. It is also the first model of optimal electricity efficiency in China with an average energy utilization rate of less than 1.2.

Qianxin: Create a "six complete" network security protection system

Under the strategy of the Winter Olympics of Science and Technology, new technologies such as artificial intelligence, Internet of Things, 5G, cloud computing, and big data will be widely used in Beijing 2022 Winter Olympic and Paralympic Winter Games, and the more data collection and sharing will be pursued, and the IT environment will become more open and complex. The complexity of the IT and business environment of the Beijing Winter Olympics, the security threats and security challenges it faces will far exceed those of any enterprise, and it is necessary to build a network security system from the perspective of informatization, with engineering thinking, and according to systematic planning.

To this end, Qianxin has launched a new generation of network security framework system for the "Science and Technology Winter Olympics". Under the guidance of the new generation of enterprise network security framework, Qianxin will establish a "six-full" network security guarantee framework system of "all-level control, all-network protection, all-field coverage, full-cycle guarantee, all-lead closed-loop, and all-service coordination" for the Beijing Winter Olympics, so as to ensure that the key systems of the Beijing Winter Olympics are foolproof and "zero accidents" are operated.

Since becoming the official sponsor of cyber security services and anti-virus software for the Winter Olympics two years ago, Qianxin has deployed nearly 1,000 sets of security equipment in more than 40 competition venues, non-competition venues and monitoring and command centers in the three major competition areas of the Beijing Winter Olympic Games, including more than ten teams such as core support detachments and emergency response detachments.

Digital Video: The first high-speed rail 5G ultra-high-definition live broadcast event

The Beijing Winter Olympics have created many world firsts, and it is also innovative for digital video to support the construction and application of the 5G ultra-high-definition studio of the high-speed rail of the Beijing Winter Olympics. The difficulty in the construction of the high-speed rail 5G ultra-high-definition studio is that on the fast-moving high-speed rail train, the base stations along the line are in a state of rapid switching, which leads to the need to frequently switch 5G base stations for the signals in the car, and the upstream bandwidth of a single base station is also greatly limited, making it difficult to transmit a 4K signal independently.

After repeated tests and program optimization, digital video finally realized the stable backhaul of 40MHz ultra-high-definition video signal to the receiving platform of the 5G media application laboratory of CCTV Headquarters.

At the same time, Digital Video provided A VS24K coding products and professional-grade 4K satellite receiving equipment for the CCTV16 Olympic 4K channel; in the Beijing Radio 8K channel production and broadcasting system, Digital Video provided a complete set of 8K ultra-high-definition program encoding transmission system including 8K ultra-high-definition codec, 8K-IPG gateway, ultra-high-definition aggregation gateway, ultra-high-definition IP scheduling and distribution matrix, etc.; in the Winter Olympic high-speed rail 5G ultra-high-definition studio, digital video deployed 4K+ 5G backpack and ultra-high-definition aggregation gateway; in addition, digital video cooperated with the broadcast team of the main station to carry out new scenario practice and testing, including 5G+ ultra-high-definition multi-view live broadcast test.
