On June 27-29, 2018, Shanghai World Mobile Congress (MWCS2018) was held. Today, with the rapid advancement of 5G, there is no doubt that the keyword of MWCS2018 is not “5G”. Including the three major operators in China, Huawei, Ericsson, Nokia Bell, Fiberhome Communications, Xinhua III and other network communication equipment and solution providers, as well as Intel, Qualcomm and other chip manufacturers were all present, shared in this nearly 4,000 conference participants, In the exhibition and heated discussion of more than 500 exhibitors, the 5G route was also more clear.
On June 14, 2018, the 3GPP Plenary approved the 5G NR Independent Network (SA) function freeze, marking the official birth of the first standard R15 of 5G. In addition to the non-independent networking NR standard completed in December last year, 5G has completed the first phase of full-featured standardization. Therefore, the commercial pace of 5G has changed from walking to jogging and running, and now it has started running fast, which means that the 5G technical solution verification and application have entered a critical stage.
The ITU defines three major application scenarios for eMBB (Enhanced Mobile Broadband), mMTC (Large Massive Connection), and URLLC (Low Delay and High Reliability) for 5G. The R15 standard focuses on the commercial demand for enhanced mobile broadband. It is reported that 5G can achieve a peak rate of 10Gbps at a bandwidth of 100MHz and a peak rate of 20Gbps at a bandwidth of 200MHz.
It can be expected that 5G will push the MBB mobile broadband service to a new height. Xu Zhijun, chairman of Huawei's rotating company, said at the MWCS that the 3GPP R15 version focuses on improving the mobile Internet experience. By the end of 2019, 3GPP R16 and later versions will completely solve the problems of massive connectivity and low latency, and assume the digitization of all walks of life. Historical mission.
5G commercial time point
In the past year, China Mobile, China Unicom and China Telecom have conducted continuous 5G tests. China Mobile has launched 5G field tests in five cities including Hangzhou, Shanghai, Guangzhou, Suzhou and Wuhan. It is expected that more than 100 5G base stations will be built during the year and 1,000 5G base stations will be built by the end of next year. China Unicom will begin testing in 16 cities including Beijing, Tianjin, Shanghai and Shenzhen this year, and it is expected that more than 600 experimental networks will be built. China Telecom will launch 5G innovation demonstration network trials in 12 cities including Lanzhou, Chengdu, Shenzhen, Xiong'an, Suzhou and Shanghai, with 6-8 stations in each city.
According to the 5G white paper released by GSMA, 40% of the global mobile operators that have announced the 5G commercial plan are expected to be commercialized in 2018 and 2019 (the earliest in the Middle East), and the other 60% plan to be commercialized after 2020. The data comes from a relatively small sample size (55 out of 800 operators); for many regions, 5G is not a recent development focus. In China, all three Chinese operators plan to officially commercialize at the end of 2020. Initial 5G commercials will be used primarily in high-density urban hub areas to test network performance and user usage levels before deployment in suburban and rural areas. In general, China's pre-commercial and commercial base stations will be among the highest in the world.
5G network transformation direction points to "cloud"
In the 5G commercial process, it is inseparable from the transformation of the network, and this transformation is even subversive. The 5G network will implement network virtualization and cloud deployment based on NFV/SDN and cloud native technology. China Mobile and Intel jointly released the "5G Independent Architecture Implementation Guide" white paper on MWCS. The white paper proposes multiple SBA (Service Oriented Architecture) solution instantiation prototypes, and gives performance test data of these solution prototypes in different scenarios. And related technology optimization solutions, in addition to suggesting a high performance SBA architecture implementation.
The SBA architecture is designed for native cloud design, especially the micro-service architecture concept. It can realize rapid deployment, dynamic expansion and shrinkage and network slicing of networks according to different service requirements through network function modularization, control and forwarding separation technologies. Full lifecycle management, including flexible construction of end-to-end network slicing, flexible scheduling of service routing, flexible allocation of network resources, and end-to-end service provisioning across domains, platforms, vendors, and even operators (roaming) .
SBA is not only one of the 5G core technologies, but also the key technology for building 5G SA solutions. The three major operators including China Mobile, China Telecom and China Unicom have clearly pointed out that the SA that has just been frozen is the main target architecture, which also means 5G networks. The direction of transformation points to the "cloud."
Vertical industry opportunities
Of course, 5G is not only the gospel of consumers, but also means more business innovation opportunities for enterprises. Lin Yiyan, vice president of Intel's data center business unit and general manager of 5G network facilities department of the network platform division, said in an interview with Zhiding.com that the vertical industry has a chance to use 5G to activate a new round of changes.
The Internet of Vehicles is a large-scale application scenario. The application scenario will be enhanced by using 5G at the latest by 2020. Of course, another new autonomous driving scenario will be obtained from the 5G-based C-V2X. Great application advantage. The transition from networked cars to long-distance driving, vehicle formation and true unmanned autonomous driving requires the support of advances in network technology. These applications require ultra-low latency, ultra-high bandwidth, large capacity, and stronger network reliability. 5G can provide these capabilities.
5G will play a key role in driving the future of smart manufacturing. It will also enable unprecedented interaction and coordination between machines, equipment and robots, making manufacturing more technical and data-driven. The combination of 5G and industrial AR and AI will unlock other application cases, such as high-precision simulation of human-computer interaction in various manufacturing environments.
In addition, smart cities, smart homes, etc. will use the opportunity of 5G to release a new round of value. The three major operators also jointly expressed that they will focus on key applications and actively carry out 5G services.
