The current domestic new crown pneumonia epidemic is generally improving, but the battle against the epidemic is far from over. The 5G network has dual functions in one network, taking into account social consumer needs and medical professional applications, and has played an important role in this epidemic. The medical virtual private network application based on the 5G public network runs through all links from diagnosis and treatment to prevention and control, deeply integrated with the scene, and assists in all aspects to suppress the development of the epidemic.
The accelerated implementation of “new infrastructure” has also pressed the fast forward button for 5G smart healthcare. Just in mid-March, the National Development and Reform Commission and the Ministry of Industry and Information Technology jointly issued the “Notice on Organizing and Implementing New Infrastructure Construction Projects (Broadband Networks and 5G Fields) in 2020″. Among the seven 5G innovative application enhancement projects, the top one is ” The construction of 5G smart medical system for major public health emergencies”. According to incomplete statistics, as of December 2019, more than 300 hospitals have launched “5G + medical treatment” across the country. From the perspective of the industry, the large-scale application of 5G To B has started with 5G smart medical treatment.
So what 5G smart medical applications have emerged during China’s anti-epidemic period? How to quickly build a 5G smart medical system in the era of “new infrastructure”? What are the key points of 5G network construction in the medical industry? The Deputy Director of the Medical Affairs Department of the China-Japan Friendship Hospital and Director of the Telemedicine Center Lu Qingjun recently shared “5G Smart Healthcare in the Era of New Infrastructure” through an online lecture.
The China-Japan Friendship Hospital played an important role in the prevention and control of this epidemic. Not long ago, the Joint Defense Mechanism of the State Council issued the “Notice on Developing Online Services to Further Strengthen the Prevention and Control of the Epidemic in Hubei”. Relying on the National China-Japan Friendship Hospital, and the remote consultation platform of some hospitals across the country, the State Council’s joint prevention and control mechanism has established a platform for severe and critically ill patients with COVID-19 National remote consultation platform. Director Lu himself is also the office director of the National Telemedicine and Internet Medical Center, the National Health Commission Telemedicine Management and Training Center, and the National Health Commission’s Primary Telemedicine Development Guidance Center. He has many applications of 5G in the front-line work of epidemic prevention and control. Explore and practice.
Fighting the epidemic: 5G healthcare is in action
5G is the new engine of the Internet of Everything. Compared with other fields in the “new infrastructure”, 5G has distinct characteristics in terms of its own driving force and its integration with other industries. In the prevention and control of the new crown pneumonia epidemic, the importance and urgency of 5G have been fully demonstrated.
The epidemic has put forward a rigid need for the Internet and information. In Wuhan, the outbreak area, the establishment of Leishenshan and Huoshenshan hospitals to more than 30 square cabin hospitals, and then 48 general hospitals became designated hospitals, bringing the challenge of rapid coverage of regional networks and medical information; lack of doctor resources , It is necessary to obtain remote support from experts from other places through the network system; in the case of personnel and material isolation, the operation of the medical system cannot be separated from the network and information technology; the emotional diversion of patients and relatives and friends caused by the isolation also makes the network and The demand for real-time video connections has increased dramatically.
“The operator completed the 5G coverage of the newly built hospital in three days, opened a 5G base station in 7 hours, and realized the landing of more than 10 5G medical application scenarios in 20 days, creating a miracle in human history!” Director Lu Qingjun did not hesitate to praise himself , And pointed out that this reflects a signal from the other side, 5G network construction speed is much faster than 4G, from the hardware facilities and construction have brought a great improvement in efficiency.
Compared with the world, 5G smart medical care has run through all aspects of epidemic prevention and control during China’s anti-epidemic period. 5G anti-epidemic applications have been launched in 22 provinces, cities and regions, and 5G has played an active role in it.
From remote diagnosis and treatment to medical assistance, to medical care, to supervision and prevention and control, a total of 18 types of 5G medical applications help curb the development of the epidemic. Director Lu said that in terms of remote diagnosis and treatment, the 5G network supports high-reliability and low-latency transmission of massive data to break through the limitations of space, through remote consultation, remote CT, remote B-ultrasound, remote ECG monitoring, cloud detection and analysis and other applications. It is possible to share doctor resources, which greatly improves the efficiency of diagnosis and treatment and reduces the risk of doctors being exposed to infection. For example, Vulcan Mountain Hospital is connected to Beijing 301 Hospital, Zhejiang Xiaoshan Hospital, Wuhan Union Hospital, and Jilin Provincial People’s Hospital based on indoor 5G+Welink connection, Hubei Provincial People’s Hospital, Union Connection Ditan Hospital, Chengdu West China Hospital More than 100 hospitals including prefecture and city hospitals assisted each other and shared the resources of more than 20,000 doctors in many places to deal with the epidemic, enabling more than 3,000 overweight patients to receive timely treatment.
In terms of 5G medical assistance, the experience accumulation of 5G robots, 5G+4K, 5G+AR/VR is applied to the medical system, through patient transfer vehicles, disinfection vehicles, delivery trucks, mobile carts, and protective wear inspections/ Guidance and other applications effectively reduce the labor intensity of hospital workers and reduce the risk of exposure and infection under the premise of timely completion of patient needs. For example, with the support of high uplink bandwidth and good mobility, 5G+ disinfection trucks/medicine delivery/truck have been installed in Wuhan Fangcai Hospital, Union Hospital, Wuhan Sixth Hospital, Wuhan Hankou Hospital, Fifth Hospital, Wuhan Central Hospital, Yangtze River It is used by more than 180 hospitals such as Shipping General Hospital and Shiyan City People’s Hospital, reducing the workload of nurses by 7%.
In terms of 5G medical care, applications such as remote visits, psychological counseling, job deployment and training, and progress live broadcasting can greatly alleviate the panic of patients and everyone about the epidemic, ease the psychological pressure of hospital workers, and deliver the latest plans in time. For example, the unified layout of the national work and the new treatment plan need to be delivered as soon as possible. The indoor 5G+welink meeting allows the epidemic work to be deployed faster. Currently, more than 700 national work deployment meetings, more than 600 hospital training and more than 100 national training sessions; and the 5G “cloud supervision” under the construction of Leishen Mountain and Huoshen Mountain has also significantly strengthened the people’s confidence in the victory against the epidemic.
In terms of 5G supervision and prevention and control, body temperature is the first indicator of epidemic monitoring. Through infrared body temperature monitoring, patrol robot monitoring, head-mounted device monitoring, drone monitoring and other means, real-time body temperature monitoring of the floating population and gathering of people have been realized. Proper management of the situation. For example, the three major operators have deployed 5G thermal imaging temperature measurement monitoring at fixed entrances and exits of more than 4,000 public places in hospitals, enterprises, and public transportation hubs across the country; and deployed 5G infrared temperature measurement mobile devices in more than 5,000 areas, using 5G good Mobility supports mobile infrared temperature measurement.
Ten points of concern for hospital 5G network construction
In his speech, Director Lu Qingjun focused on sharing the ten major concerns of hospital 5G network construction, involving network architecture, construction path, overall intra-hospital networking, intra-hospital networking selection, network security, network performance, radiation, medical modules, construction Many topics such as network model and business model. Whether from a realistic perspective of epidemic prevention and control, or a long-term perspective to promote the development of the medical and health industry, it provides very valuable ideas and references.
Concern 1: How to build a 5G smart hospital?
At this stage, the 5G smart medical system architecture is still “cloud (platform)-management (network)-end (terminal)-use (application)”, and corresponding system planning and deployment are required at all levels. From the cloud perspective, the platform needs to be built for different users and technical characteristics, especially the scope of use. Common examples include inter-hospital telemedicine platforms, in-hospital digital hospital platforms, and regional health platforms of governments and public health organizations; Spectrum isolation, QoS guarantee, and future slicing technology form a virtual private network based on 5G public network and one network, and use different connections to deal with different data transmissions; terminals and applications can be grafted to facilitate clinicians to discover more scenarios. The ultimate goal is Serving clinics and patients.
Focus 2: Where did the smart hospital start?
The path of 5G smart hospital construction is “1+3+4+N”. “1” means that a 5G network needs to be built in the hospital to give full play to the 5G high-bandwidth information transmission capabilities, low-latency information interaction capabilities, and large-capacity access capabilities of large connections, multiple terminals and multiple devices; “3” represents wisdom There are three basic platforms that the hospital needs to build. The construction standards issued by the National Health Administration point out that smart hospitals include “smart medical systems, smart management systems, and smart service systems”. The smart medical system corresponds to clinicians and the smart management system corresponds to medical treatment. Managers and smart service systems correspond to patients; and “4” represents 4 basic platforms and application systems for different fields and different business models, including in-hospital, out-of-hospital, medical management, logistics and distribution in the existing medical system; in On this basis, “N” 5G medical applications are finally formed.
Concern 3. What kind of network does the hospital need?
The answer is that it needs to be able to seamlessly connect the network inside, between the hospital, and outside the hospital. In terms of implementation, the pre-hospital 120 first aid and in-hospital specialist first aid are combined through the 5G network to establish a two-way transmission system of network information from the place of the incident to the hospital emergency center; the inter-hospital interconnection and emergency treatment of multiple hospitals in large general hospitals The network system forms a coordinated network connection from the local unit through the 5G network, which is expanded and sublimated based on the original platform architecture in the early stage.
Concern four: How to select the 5G networking solution for the hospital?
There are two options for networking modes. One is a dual-purpose network, that is, To B/To C hybrid networking, which can not only meet the needs of individual users within the hospital, but also realize hospital medical applications through UPF sinking; The second is the industry private network, To B is a separate network, and the operator’s core network directly connects to the hospital network, and the hospital wireless equipment is exclusively used. From the current stage, the dual use of one network that takes into account the social consumer demand and medical professional applications is obviously more practical. Based on the dual use of one network, the hospital can use 5G earlier than the end-to-end private network; operator one network With dual use, To B and To C income can be obtained. Combined with the standardization and standardization of 5G medical applications, 5G hospitals can be rapidly deployed and replicated in large numbers, thereby leading the 5G To B practice with scale effects.
Focus 5: How to ensure the reliability of medical data transmission?
The 5G network has carrier-class high reliability. At present, there are two solutions to ensure the reliability of the network. The hospital can choose according to the purpose of use. Solution one is to realize 1:1 hot backup for pRRU, RHUB, BBU baseband board and main control board; solution two is RHUB link backup, pRRU point position considering redundancy design, and adjacent pRRU to realize mutual assistance networking.
Sixth, how to connect medical equipment and modules?
The development of 5G smart medical care is inseparable from the development of 5G modules. Without modules, terminals will not be able to access 5G networks. From data collection to transmission, to wireless networks, modules are important connection points. The current modules are also developing at the same time. The USB interface mode can be continued in the first stage, and large-scale medical equipment can be integrated. For existing medical equipment such as doctor terminals and personal workstations, plug-in forms can be used to connect through the USB interface; the second stage is built-in 5G modules are also under rapid development.
Focus Seven: How to ensure security?
5G has a complete security plan to effectively protect the security of the network through service domain security, enhanced integrity protection, enhanced inter-network roaming security, and unified authentication architecture. In addition, 5G based on network perception can also realize pseudo base station monitoring (anti-counterfeiting base station) and supervision of secure tunnels.
Concern 8: Does 5G radiation affect health?
5G radiation will not pose a threat to human health. Radiation is divided into two types: ionizing radiation and non-ionizing radiation. Some of the radiation we are exposed to daily, such as mobile phones, Wi-Fi, communication base stations, etc., are non-ionizing radiation with lower energy. The increase in 5G network speed is not achieved by increasing the transmission power of 5G base stations, but by expanding the transmission bandwidth. In terms of transmitting frequency standards, 5G base stations and 4G base stations have the same standards, and both must meet the national standard of “less than 40 microwatts/square centimeter”. The radiation of 40uW/CM2 of 5G micro base station is 8uW/cm2 measured in China-Japan Friendship Hospital, which is much lower than that of household appliances.
Concern 9: How to provide 5G networks in hospitals?
At present, there are two main delivery modes. Mode one provides 5G To B scenario-based network solutions for telecom operators, hospital information service integrators provide third-party applications, and operators are integrated; mode two provides 5G To B network equipment vendors Scenario-based network solutions are provided to medical enterprise customers after the hospital information service integrator is integrated. It is worth mentioning that after the release of the “Hospital Network Construction Standards Based on 5G Technology” in October 2019, industry solutions guided by the “Standards” have made major breakthroughs, such as Huawei’s LampSite EE for enterprises. Provides industry solutions with 5 major capability sets, which can meet the local ultra-large capacity and high-speed upload requirements, the ultra-low latency requirement stable at the level of 99.999%, and the requirements for centralized real-time access and high-precision positioning of a large number of devices.
Focus ten. How to establish a business model?
The traditional 4G charging model is based on bandwidth traffic, while 5G is more about introducing services, including independent networking, network slicing, and network resource allocation. It is a new type of service provided by manufacturers, service providers, and operators. Therefore, the business model has become diversified, such as traditional traffic payment, payment based on MEC node services, payment for technical support, and payment for knowledge base knowledge. At present, the overall business model is still in the discussion stage and is subject to mutual consultation by all parties.
While placing high hopes on the innovation and application of 5G in the medical industry, we must also be aware of the particularity of the medical system. At the end of the speech, Director Lu also put forward two points worth considering.
First of all, medical treatment is different from e-commerce. Therefore, the medical system needs a comprehensive, comprehensive and mature solution, which needs to consider the risk probability in case; and smart medical care is composed of various comprehensive applications. Some applications may be implemented in certain scenarios but face many problems in promotion. Partially general.
Second, medical care is not a commodity, but it must conform to economic laws. Medical care is of a public welfare nature and belongs to the protection of people’s livelihood. It cannot be completely free, and it must also refuse profiteering and monopoly; at the same time, because medical care cannot target pure profit, the cost recovery cycle is long; medical care requires industry access, and 5G innovation must also comply with legal standards , And conform to the development law of the medical system.
As the host of this online seminar, Min Dong, deputy director of the China Academy of Information and Communications Technology Medical and Health Big Data and Network Center, also summarized some consensus on the follow-up development of 5G smart healthcare based on speeches, discussions and related policies, such as further improving 5G+ healthcare Standards system construction, 5G+ medical and health application pilots, 5G medical equipment and module testing environment, strengthening network security and medical service quality assurance, etc.
It can be said that this online lecture has effectively sorted out, summarized and authoritatively interpreted the current progress, environmental situation and network construction concerns of 5G smart medical care, and provided guidance for the next development. Facing the future, 5G smart medical care that has undergone the “big test” of the anti-epidemic will surely usher in an overall leap in the era of “new infrastructure”, providing stronger support for domestic and foreign medical and public health services, and realizing “5G+ medical care”. “The vision of universal benefit meets the health needs of the people for a better life.
