The scale of global telecommunications operators is largely inseparable from the formulation of communication standards. The main organization is 3GPP (3rd Generation Partnership Project), and 3GPP2 is also included. The formulation of communication technology standards is to maximize the solution of technical barriers and construction costs between industries. When MEC (Multi-ACCESS EDGE Computing, multiple access edge calculations) proposed, the 4G LTE network standard has been formulated. Therefore, most of the MEC under 4G networks currently use manufacturers' private standard deployment models, resulting in its supervision, security and billing charges There are certain problems. It also caused the 4G era MEC to have large -scale commercial deployments in both abroad and domestic. The emergence of 5G communication technology has once again lowered the communication cost, so that the new complex tasks can be executed in a remote manner and form a edge computing mode.

The development of communication technology and the digestion of the media industry may belong to two sine wave curves. Now it seems that the peak of communication technology has arrived, but the media industry has not been synchronized and matched. In terms of standards, IMT-2020 (5G) has achieved global unification, but it is difficult to standardize in the case of industry-oriented applications. How to find demand in the vertical market of media technology companies and provide the best target solution. How to pull away the common network capabilities from fundamentals to help the digital transformation of the media industry? To answer this question from the technical dimension, the answer is likely to be 5G edge calculation. In the era of big data and the Internet of Things, the traits of edge computing can effectively supplement and improve the corresponding functions of cloud computing to overcome issues such as overcome bandwidth pressure, delayed problems, and waste of computing power costs.

5G edge computing feature overview

Multi-access marginal computing (MEC) provides IT service environment and cloud computing capabilities for mobile network edges. It offsets the delays of the return journey by performing some cache, data transmission and calculation on the edge of the mobile network. Millisecond application. Deploy rich applications on the edge of the network, improve the user experience, and better meet the needs of end user needs.

5G edge computing industry status quo

ETSI startup members include: Hewlett -Packard, Vodafone, Huawei, Nokia, Intel, etc. MEC provides the IT service environment and cloud computing capabilities for the edge of the mobile network. It offsets the delay of the return and the delay of the return journey by performing some cache, data transmission, and computing on the edge of the mobile network.

In the 4G network, RGW (Remote Gateway) was used for marginal deployment, and the value brought by MEC to users was first tasted; after the gateway equipment CU was separated, the separated U surface device (DGW, Distributed Gateway) was deployed on the edge or area Provide users with the ultimate business experience; when they evolve to 5G, natural CU separate, and the UPF and MEC platforms of the U surface are jointly deployed on the edge or area. Combined with the powerful network capabilities of 5G, they can develop and innovate more MEC business.

In general, the edge computing industry has moved from technical governance to industrial consensus. The most terrible industrial development is not capital expenditure and resource investment, but the misleading guidance of the industry. China Mobile, China Telecom, and China Unicom, represented by operators, all deploy a large number of 5G MEC base stations, including network capabilities and computing resources, and gradually formed a "L" development form. The three major operators build and provide a 5G special network network service on demand and provide cloud network. The construction of vertical network resources has actually entered a climax, and the horizontal development cannot be found. The centripetal force between the industry is far greater than the technology itself, and the steps of positioning, focusing, and empowerment are indispensable. 2.1 5G edge computing industry positioning

In terms of positioning, the final goal of the definition of edge computing is commercial practice. Telecom operators have the advantages of marginal infrastructure and irreplaceable network capabilities. It is associated with the core network sinking upf (User Port Function, user face function) and wireless side GNB (Next Generation Node B, 5G base station). Internet companies occupy an advantage in marginal computing components, IoT platforms and applications and customer resources.

2.2 5G edge computing technology fusion

Technically, the main purpose is to reduce delay. At present, there are many companies that integrate IT to OT. Many of the basic forms that IT enter the edge computing include N3 UPF and 5G small stations. Facing the current network architecture for decoupling is the original intention. At present, the operator is mainly pushing the 5G special network, and the edge calculation is only one of the carrying capacity platforms.

2.3 5G edge calculation main form

In terms of development, the edge network appeared in the wireless network system for the first time, which is both a resource computing platform and a wireless network capability platform. From the perspective of the cloud edge, the private cloud will be calculated and developed by the edge. Although this industry is on many problems, it is still exploring. In the long run, edge computing will be used to manage the application of private clouds, public clouds, and mixed clouds, which is a trend. The development of technology was originally a process of coordination and optimization of resources. The development of edge computing involves three major blocks -cloud edge, cloud net, and edge.

5G edge computing and media industry development strategy

The emergence of any new technology requires two necessary conditions: one is that economic and social development has a strong demand for this technology, and the other is that a series of basic technologies related to this technology have developed sufficient development.

3.1 Demand of the Media Technology Industry

Video edge computing capacity frameworks in the media industry have five major technical characteristics: providing basic common video processing functions such as video acquisition and codec can be provided for the application needs of video edge computing to adapt to various scenarios; , Support the edge reasoning and distributed training of AI models to achieve federal learning; use virtualization and container technology, and pipe a variety of types of video edge devices; unified management of platforms that support edge equipment to reduce management expenses; compatible general processors and more The edge equipment implemented by the type of video smart chip reduces equipment costs and development costs. Implement all frequency band access (super upward) of Sub 6GHz, support access to fixed network and mobile network, optimize the shortest MEC access network, and provide the shortest path from GNB to MEC UPF's N3 interface service stream. In the on -site MEC mode, the mobile carrier router in the media technology park is needed to transfer the N3 interface service to MEC. Not only ensure low latency and save width on the operator's network, but also to ensure that the key service data of media technology companies will not leave the park.

3.2 5G edge computing technical business development

From the perspective of commercial practice, the fundamentals from the reduction to the efficiency are reduced costs. In fact, it is to meet the simple supply and demand relationship. You can also choose to create and meet the supply and demand relationship, continue to optimize, and then to the balance of supply and demand. It is an inevitable trend from the consumer Internet to the industrial Internet. From the perspective of telecommunications operators and media technology industries, how to effectively intervene in the transformation of the industry to achieve element -driven. The new infrastructure policy of REITs (Real Estate Investment Trust) promotes IDC development. REITs allows IDC traffic and industrial integration. 5G MEC can be used as capital factors. Guided by digital business strategies, the technical capabilities of traditional media technology industries have gradually extended to the upstream of the industrial value chain. The change of organizational structure has become extremely important. It will drive the professional capabilities of various lines to upgrade the media and technology capabilities of the media, and break the value chain technology barriers.

5G edge computing and media industry development recommendations

4.1 Select a reasonable technical route

According to the current development, MEC's main and key is the development of industry applications, which is also the most lack of at this stage. The analogy is a model of the development of 2C business -AATORE, it is recommended to develop and choose from two directions, that is, the south slopes and the north slope. Among them, Nanpo Index's high-quality connection mode, it takes 5G high-quality connection as the core grabbing point, integrated service, is an alternative to the current fiber or Wi-Fi network. The North Po refers to the use of platforms that understand operations to enrich the cooperation ecology, reduce the total cost of industrial chain, and change the existing business model. 4.2 Focus on the scene completion verification

As of the end of 2019, a total of 70 pilots of 5G edge computing projects participated in the construction of a operator have covered 10 vertical industries. According to the coverage area, it can be divided into pan -park -type business and universal service business. Each vertical industry projects are involved. 82% of the businesses are pan -park -type business. The needs of industry, media technology, and parks are urgent, accounting for 70%of the number of pilots, and are the key vertical industries for marginal computing development. Among them, in the deployment of the media technology industry park, it is recommended to take the lead in using MEP's ability to complete the verification.

4.3 Industrial planning moderate forward

In the later period, the number of related MEC APPs in the media industry has increased dramatically, and the credible mechanisms between development and traders need to be improved and established in a timely manner. Create a new ecosystem that belongs to the media technology industry.

4.4 Data security key guarantee

The overall security protection solution on the edge computing is to provide basic network security capabilities and demand security services for customers of media technology vertical industry with the existing capabilities of the Internet. UPF and core network security protection. UPF, as a user -faced network element of the core network, is deployed on the edge nodes with lower material security levels, which should have physical protection. And core attacks on the edge; SMF and UPF requires two -way authentication to avoid falsifying SMF/UPF strategies. On the media side, the UPF connects the core network through the transmission network, which needs to ensure the security of the transmission link between the UPF and the core network; the UPF level forged a packet to attack the anti -DDOS to avoid reposting a large amount of malicious traffic to the small -capacity MEC APP. Edge applications need to be followed by two types of security services: basic security functions and security capabilities are open. Basic security functions refer to the security guarantee function provided by traditional security equipment and safety tools. For specific applications, customized exclusive functions are required, including VIPS/IDS, transmission channel encryption, virtual patch, etc., as well as Anti-DDOS, Anti-Virus , Vulnerability scanning, safety baseline inspection and other conventional security services.

Conclusion

Edge computing is one of the most exciting new concepts in the digital world. It breaks the traditional cloud computing boundary and is the next competitive highland after cloud computing, which allows access to a more efficient and stronger network architecture. Gartner predicts that by 2022, edge computing will become a necessary demand for all digital services. 40% of large enterprises were included in the edge computing in projects in 2021, and less than 1% of enterprises were implemented in 2017. According to the analysis of the research company Stratistics MRC, the edge computing market in 2017 was about $ 8 billion, and it is expected to reach about $ 20.5 billion by 2026.

From the cultural threshold to the technical threshold, it will appear muddy water to touch the fish when it is "big". It is critical to define the technical threshold. The most terrible industrial development is not technology input and capital expenditure, but the misleading guidance of the industry. Starting from the perspective of independent, there is one -sided understanding and cognition, and the deviation is gradually formed and solidified. Standards come from demand and technology goes to the market. Whether it is edge calculation or 5G, it is essentially a technical means and implementation method, but it is expected to solve the main contradiction between communication technology and industrial needs.

5G from technology connection to value connection, alleviating and gradually resolving the main contradictions between the needs of communication technology and the media industry. Created new opportunities for media science and technology segmenting industry markets to promote new growth in edge computing revenue.
