The 2019 China mobile partner conference, an industry event, is well underway.The conference, focusing on '5G+', officially sounded the general clarion call for China mobile to continue to cooperate with many partners to truly build 5G into the aorta of social information flow, the accelerator of industrial transformation and upgrading, and the new cornerstone of digital social construction.As a complex cross-industry ecological integration system project, '5G+' is facing challenges in technology, product and business, market and many other aspects.From 5 g WeChat public platform (ID: angmobile) during the conference vice President of zte, TDD & 5 g product BaiYan people and zte vice President nelson liu, general manager of depth interview, it seems, zte has fully ready to welcome the challenge, help to make the world's highest scale, the high quality products of China mobile network and realize the whole business of preparation.

5G black technology, to solve the '5G+' technical challenges

After the ministry of industry and information technology (miit) announced the official launch of 5G commercial service on October 31, the GSA association released the latest statistics on November 1, the day of China's official 5G commercial service. 50 operators in 27 countries have launched 5G commercial service, including China mobile, China telecom and China unicom.On the one hand, this shows that operators around the world are far more enthusiastic about 5G commercialization than previous generations of mobile communication systems.On the other hand, it also shows that China is in the first camp of 5G commercial.Thanks to our country after 5 g licences issued on June 6, boutique 'place' in the first phase of 5 g network construction, which can not do without the positive support of mainstream equipment suppliers, zte, for example, according to BaiYanMin, zte's first complete three carriers 5 g issue of shipment, and the first delivery, and network quality lead - in guangzhou, shenzhen, Beijing and other places to build the 5 g area network benchmarking net rate of more than 1000 Mbps, which, in the process of China mobile's 5 g base station delivery milestone first created more than 5 g commercial process.

At present, both foreign and domestic 5G commercial networks are still in the early stage, and almost all 5G commercial networks use NSA networking and eMBB services.It is reported that China will carry out phase ii SA commercial network construction in 2020, laying a solid network foundation for '5G+'.It is expected that the main frequency band for phase ii 5G commercial outdoor network construction of China mobile will still be 2515-2675mhz, including td-lte current network band 60mhz.It can be predicted that in the early stage of 5G commercial use, 4G traffic will still grow rapidly, 4G network coverage and capacity demand will remain the top priority, which increases the complexity of China mobile's overall planning for the construction of 5G network (such as overall planning for phase I and phase ii 5G network construction), so it is necessary to strengthen 4G/5G collaborative networking to create greater value.According to bai's introduction, zte considered 4G/5G collaboration and the smooth evolution from NSA to SA target architecture in advance in the first phase of China mobile's 5G construction.

He introduces, in the construction of a period of 5 g, zte to fully support China mobile's '160, 192 days, 64 MHz large bandwidth channel' high standard requirements, the deployment of 4 g / 5 g common-mode equipment, rapid implementation of 4 g / 5 g fusion network -- with 5 g equipment reverse opening early in order to solve 5 g commercial 4 g '5 g equipment idle and 4 g flow surge', the future can be a key to remote upgrade the software to quickly implement support 2.6 GHz 160 MHz band 5 g NR, need not artificial NR on the deployment of 160 MHz bandwidth red 5 g;In addition, the use of 4G/5G common mode equipment, through BBU integration, sky integration, supporting equipment and other comprehensive planning of installation and construction, can effectively reduce cost, increase efficiency, energy saving and emission reduction -- for example, the deployment of 4G/5G common mode AAU can reduce the construction of a set of td-lte d-band equipment, thus reducing equipment power consumption, tower rental cost, and saving optical modules.

On the other hand, it is also important for China mobile to protect the phase I NSA investment and smooth the evolution of NSA to SA in the future.According to bai yanmin, zte NSA&SA dual-mode base station can realize smooth evolution from NSA to SA through software upgrade in the future. This 'one-step hardware investment' approach can save the investment cost of operators, and end users do not need to replace the previous NSA phones, thus effectively avoiding the loss of operators' users.'Zte's full range of 5G base station products meet the construction needs of different scenarios, ensuring that China mobile can build a 5G premium network,' he said.In addition, he also introduced zte's 5G 'black technology' to 5G WeChat public platform (ID: angmobile) -- fully switching to devices using 7-nanometer chips. In this way, the size and power consumption of AAU will be greatly optimized, so as to solve the problem of large energy consumption of 5G, make 5G truly large-scale commercial use, and solve the worries of operators.'For the second phase of 5G commercial network construction, our 5G AAU commercial products can adapt to different scenarios and different cost requirements,' said bai.

The industry has long been known as '5G construction, load first', for example, it is reported that by the end of September, the global operators and zte cooperation completed more than 30 commercial deployment and pilot 5G carrier network.According to nelson liu, zte can meet operators to build sustainable development, covering the whole life cycle of 5 g, 5 g bearing network the core appeal, oriented to the NSA/SA, the prequel/in/back, new/evolution, such as the whole scene, for bearing the whole series of 5 g chip, and by adopting FlexE flexible (Ethernet) 'hard isolation' in order to ensure the resource allocation of different business.

The future norm will be 'long-term coexistence of 4G and 5G'.By introducing the concept of 'virtualization', 5G core networks (5GC) can be quickly deployed on common servers and different service combinations of network functions can be realized through micro-services. Thus, the fusion of 4G and 5G core networks is technically possible.Therefore, the introduction of 4G/5G fusion core network is the key to the future integration of NSA and SA network, which can protect the network and terminal investment at the initial stage of 5G network construction to the maximum extent.As for the 'brain' of 5G system that operators attach great importance to -- 5GC, liu jinlong revealed the latest information in this interview. For the construction of 5GC that will start at the end of this year, zte can provide core network with slicing capability and full business operation.

The Open currency, tackling the '5 g +' products, business and market challenges

In terms of products and businesses, '5G+' faces many challenges, including fragmentation of equipment interfaces in various industries and incomplete integration of cross-industry interfaces.Various industries have diverse needs for digital transformation, and the cost of specialized and customized solutions is high.There is an inherent life cycle of industrial equipment, and the cost of transformation and upgrading is relatively high.In addition, '5G+' also faces many challenges in market development, including the great differences in knowledge structure and thinking mode between the telecommunication industry and the vertical industry (' barriers 'to the vertical industry);Market-oriented business models need to be further explored;The rapid development of new scene and new business brings challenges to the cross-industry regulation.

The key to solving these challenges lies in extensive and in-depth cross-industry cooperation.China has been carrying out relevant exploration for a long time and has achieved phased results so far.- the largest 5 g fusion application value to industrial interconnection as an example, the scene is highly fragmented, if want to introduce 5 g, industrial enterprise needs to reorganize, upgrade process defining the business way, operators, enterprises are facing many challenges, under the joint efforts of the parties in the industry chain has been a major breakthrough, such as in the second 'blossom cup' contest, 5 g applications in jiaxing jointly by zte mobile, 5 g of new fengming group to build intelligent workshop project, give full play to the advantage of 5 g, the traditional factories to achieve full digital upgrade, finally emerge from the national 3731 projects, won the first prize.Liu jinlong introduced that another typical case is that liaoning mobile, anshan steel group and zte jointly built the world's first 5G+ smart steel enterprise. This is the first time that 5G technology has been integrated into the manufacturing industry on a scale and formed a complete business plan, marking a key step in the application extension of 5G+X and integration into thousands of industries.He further said: '5G+ motor life cycle control system, 5G+ machine vision strip surface detection system, 5G+ machine vision belt corridor security system, equipment remote control system, etc. have been fully applied in anshan iron and steel group, forming products for commercial promotion to the metallurgical industry.

In the interview, from nelson liu is introduced, in the face of large difference of vertical industry is highly fragmented, demand, zte in joint operators, each key vertical industries head enterprises explore 5 g in the process of the application of ecological development, has formed the development of 5 g fusion application 'methodology' - '1 (5 g + MEC acme network) + 5 (zte five major business China) + X (open to one thousand for any profession 5 g network capacity and business can assign)' strategy,Remarkable achievements: established cooperation with a number of industry-leading product providers and industry customers (including 'industry leaders' such as sany heavy industry, xinhua news agency, faw group, gac group, guodian nanzi and xuji electric), built more than 30 5G+ series solutions and built more than 50 demonstration projects;At the same time, make the basic preparation for the full docking with the operator, and quickly promote the terminal side module.

B2B and B2B2X will be the biggest market opportunities for 5G in the future, according to GSMA's global mobility 2020.In '5G+', end-to-end slicing and MEC are the two key enablement.5G's slicing capability realizes the end-to-end encapsulation of network, computing, storage and other capabilities, and is the main entrance to external services.The MEC capability of 5G has built an important information infrastructure, which is a key node for operators to cut into thousands of industries and a core grab for extracting market value.Looking forward to the coming future, liu jinlong introduced that slice mall and MEC of different orders of magnitude can be deployed in 2020.

Create value, and good world

Up to now, China has made significant achievements in 5G technology standards, product research and development, application exploration and policy support, etc. The commercial construction of the overall 5G scheme, terminal, business and other ecological chains has been completed, the industrial application has entered the actual implementation stage, and the future business model is also in gestation.It is believed that China will take solid steps in 5G development from 2020.Looking ahead, '5G+' will create a new model of opening up and cooperation, stimulate new drivers of economic growth, and create new opportunities for social development., zte, in 2019 China mobile partner conference proposed 'connect the preconditions, control escort, realize the whole business management' strategy, 5 g WeChat public platform (ID: angmobile) believes that this reflected as China mobile's strategic partner, always walk in the industry forefront of zte for all partners hand in hand to help China mobile 5 g + to create value, and good confidence of the world.
