May 29th (Jiang Junmu) In the past ten years, Huawei's SingleRAN's "Ocean Exploration" has successfully promoted the booming of mobile broadband and the explosion of digital applications, bringing tremendous changes to human society; facing the value of the telecom market Drive "change", in the face of the upcoming 5G era, SingleRAN Pro will sail again. On the eve of the 2018 Huawei Global Analyst Conference, Huawei officially launched the SingleRAN Pro globally through a unique media conference. Based on long-term innovations in mobile communication network architecture, hardware products and even operation and maintenance, we introduce cutting-edge technologies such as 5G, cloud computing and artificial intelligence. SingleRAN Pro is "All in One", "Agile Architecture" and "AutomaTIon". The feature helps operators overcome difficulties and cross the three major challenges of the 5G evolution road to build a smart world of “Internet of Everythingâ€. "Zhuangzi · Health Master" cloud "refers to the poor for the salary, the fire pass, I do not know how to do it." From SingleRAN to SingleRAN Pro, it has become a specific technical means. The constant is the kernel that solves the business problems of operators and supports the commercial success of operators. Speaking from SingleRAN Referring to SingleRAN Pro, let's first review SingleRAN, a solution that has been deeply imprinted in the history of mobile communications. It was originally conceived from a meeting between Huawei and Vodafone. From 2007 to 2008, it was a critical period for the development of mobile communication 3G, and the global environment at that time was just a financial tsunami that never happened in a hundred years. This makes mobile operators have the urgent need to deploy 3G infrastructure to keep up with the trend and continue to extend the 2G network life cycle in the early stage of 3G profitability, and more cautious in network investment. At a meeting in February 2007, Vodafone experts proposed to Huawei that they hope to build a network in the 900MHz frequency band, initially supporting GSM and upgrading software to UMTS, thus saving a lot of investment and operating costs. This concept has attracted the attention of Huawei, but because the industry has not yet had relevant technical support and application precedents, it is extremely difficult to implement. The entire wireless product line has devoted all its efforts to research and development, and has overcome a series of difficulties. Finally, it took out the world's first GSM/WCDMA/CDMA/WiMAX/LTE multi-system common platform Huawei fourth-generation base station. Launched the SingleRAN solution for the core. The concept of SingleRAN is "one network architecture, one engineering construction, one team maintenance". In short, it supports the integration and evolution of different technology systems through unified R&M management, unified radio resource management, unified network planning system optimization, and unified transmission resource management, which makes it a network evolution and The perfect solution to the contradiction between technological revolutions. In 2008, Huawei successfully delivered the world's first GSM and UMTS converged SingleRAN network in the German O2 project. As the "pain point" problem was seized and solved, the SingleRAN solution and Huawei's fourth-generation base station immediately became the darling of Vodafone, Deutsche Telekom, France Telecom, Telefonica, TeliaSonera, Telenor, Belgian Telecom and other leading operators. There has been a wave of deployments sweeping across the globe, and it has become a standard for networking in other senses. In the follow-up, Huawei continues to introduce new standards and technologies within the framework of SingleRAN, and continues to innovate. While helping major operators solve the practical problems faced by the business development process, Huawei also makes the transition from 3G to 4G and even 4G continue to evolve. Become a smooth road. As of the end of 2017, more than 600 mobile networks around the world have chosen Huawei's SingleRAN solution – from Norway's northernmost northernmost point (in the Arctic Circle), to Russia's ice and snow, to Germany's rural areas, to the deserts of Namibia, to the Philippines. The tropical rainforest and the southernmost tip of Australia's world, SingleRAN's footprint has spread all over the world on six continents. SingleRAN Pro: Facing the three challenges on the 5G road History is always strikingly similar, and today's mobile communications industry has reached a new crossroads. With the demise of the demographic dividend, the development model of “covering and building a station can make money†is gradually unsustainable. The entire telecom market is undergoing a transformation from “investment-driven†to “value-drivenâ€. The emphasis on return on investment and return cycles has led operators to focus more on user experience, services and greater value for their users, and look forward to discovering new business models and revenue sources beyond voice and data. In fact, many mobile operators have already taken action and achieved positive business results. For example, in the case of fixed-mobile convergence (FWA), in 2017, the number of broadband accesses through wireless access exceeded the use of fixed access, meaning that FWA applications are becoming more widespread. In terms of the Internet of Things, more than 500,000 sites have the ability to support NB-IoT, generating tens of millions of NB-IoT connections, and mainstream operators including the three major operators in China have launched NB-IoT packages; Structural changes in the industry such as networking and industrial Internet are also emerging. The common concern about network delay also brings opportunities for cooperation between operators and OTT. For example, China Mobile is cooperating with Tencent in the field of games. For this reason, 5G has been placed on more expectations, and the pace of standard setting has been accelerating. Based on the characteristics of large bandwidth, low latency, high reliability, and massive connectivity defined by the ITU, 5G will enable the vertical industry and become its intelligence while bringing the ultimate user experience and pulling the business cycle by releasing traffic demand. The base of transformation has provided a “knock-knock†for operators to participate in the “everything interconnected†trillion-dollar market, which has given birth to unprecedented new growth opportunities. However, on the road to the evolution of 5G, there are still thorns and challenges. Huawei integrated multiple operators' 5G appeals and its own mobile communication industry development insights, and summarized them into three points - Challenge One, how to build 5G networks quickly and cost-effectively? Challenge 2: How to allocate 5G network resources agilely and flexibly to achieve maximum network revenue? Challenge 3: How to efficiently manage increasingly complex networks to reduce operation and maintenance costs? "In order to match the intelligent society and vertical industry development of 'Internet of Everything', the appeal of 'supporting multiple services with one network' has replaced 'one network to support multiple standards', becoming the main contradiction at present." Huawei wireless network product line President Deng Taihua earlier proposed at the 8th Global Mobile Broadband Forum at the end of 2017 that operators need to build three capabilities to deal with, that is, build strong network capabilities to support capacity, coverage and latency requirements for multi-service development; Agile and flexible network deployment architecture to improve the efficiency of multi-service connection bearers; build intelligent network management capabilities to provide efficient network operation and maintenance and multi-service experience optimization. “All operators are complaining about high operating costs (OPEX), and even higher than the cost of network construction (CAPEX). This situation is getting worse. At the same time, the development of the network, the iteration of new knowledge and equipment, and the management of operation and maintenance are also proposed. Higher requirements even exceed the knowledge reserves and capabilities of personnel.†Zhou Yuefeng, chief marketing officer of Huawei's wireless network product line, pointed out that 70% of major network failures are caused by human factors such as misuse. The market is calling for a new solution, and SingleRAN Pro was born. Three highlights support operators to continue business success Based on the success of SingleRAN, SingleRAN Pro provides mobile operators with more capabilities to support their business opportunities, achieve new growth, and achieve continued business success. Specifically, these capabilities are reflected in three highlights. The first is "All in One", a network that supports 5G compatible 2G, 3G, 4G network platforms. SingleRAN Pro provides a unified hardware platform that enables fast and efficient build of 5G target networks and is backward compatible with 2G, 3G and 4G. Compared to SingleRAN's baseband and RF hardware resource multi-system sharing, “All in One†extends the concept of “integration†to maximize resource efficiency and protect operators' existing investments. Taking the sky surface as an example, the SingleRAN Pro supports multi-mode to multi-band multi-antenna. For large-capacity scenes, there is also a series of Massive MIMO for multiple scenarios. In addition, the high integration of hardware platforms such as integrated BBU is not only beneficial for 5G fast. The introduction also greatly simplifies the site space, thereby reducing site energy consumption and reducing site maintenance costs. Followed by "Agile Architecture", a network that supports the agile network architecture of operators' multi-service development. SingleRAN Pro mobile cloud-based architecture includes three major connotations, network architecture cloud deployment, a flexible software architecture to support on-demand deployment of different scenarios of operators, Distributed RAN (base station distributed scenario), Centralized RAN (base station centralized scenario) CU-DU separation (base station separation deployment scenario); spectrum resource cloudization, dynamic allocation of spectrum resources on demand through CloudAIR, rapid introduction of new technologies, improved spectrum utilization; air interface capacity cloudization, on-demand definition of air interface through network segmentation , define the network by business. The three characteristics of efficient resource utilization, on-demand deployment of network elements, and agile service delivery will help the carrier network enable vertical industry new services to maximize asset value. Finally, "AutomaTIon" is a smart wireless network that is automatically managed by a network. In the 5G era, operators face far more operational challenges than before. Multi-system coexistence, multi-service parallelism, more complex network resource management, and differentiated QoS guarantees for new vertical business are also difficult to achieve. With AI-based network optimization, automated operation and maintenance, and new network capabilities, SingleRAN Pro will bring smarter brains to operators' wireless networks, bringing three major values—driving network operation and maintenance and simplifying construction. Dimensional capabilities; further release of network potential, beyond performance limits; enabling more new business new capabilities, making more possibilities impossible, and finding automation solutions for problems that many people cannot solve. Although the SingleRAN Pro solution has just been launched, many of the technologies used have been deployed globally. According to Zhou Yuefeng, by deploying Huawei's "1+1" antenna (one antenna supports the frequency band below 3GHz and one reserved for the 5G sky surface), Deutsche Telekom has to meet the needs of the future development for 5G 3-5 years, avoid frequent Replacing and protecting its investment; in Thailand, where the mobile market penetration rate is as high as 124%, the deployment of 4T4R effectively helps True to differentiate users with differentiated business experiences and services, and grows into the country's second largest mobile operation in a fiercely competitive environment. Business; wireless home broadband business is developing well, bringing “happiness troubles†to the Philippines Globe with insufficient capacity in the hotspot area. Deploying Massive MIMO frees user traffic demand and speeds up the network, and shortens the payback period from the commercial level. . The shortage of spectrum resources has made it impossible for Ufone in Pakistan to develop LTE business. It has been behind other local operators for more than one year. CloudAIR helped it to plan LTE deployment in the first half of the year, avoiding the lapse of users and maintaining the investment confidence of the parent company; 5G evolution of the new generation of large-capacity BBU (baseband board), Huawei BBU5900 supports a larger specification of 64T64R Massive MIMO cell, helping Turkey Turkcell build a 5G target network to achieve continuous leadership; in terms of operation and maintenance, Japan Softbank deploys automated operation and maintenance The management platform mAOS, based on big data and artificial intelligence, shortened the optimization of Massive MIMO for 20 days to 7 days. These early use cases have shown that there is tremendous kinetic energy in the SingleRAN Pro. In the next decade, in front of everyone is an era of rapid change than ever before, and the mobile communications industry is accelerating its sinking into the foundation of a smart world that enables the “Internet of Everythingâ€. At the 8th Global Mobile Broadband Forum, Huawei shouted the idea of ​​“mobile reshaping the worldâ€, regardless of the forward-looking concept, the leading edge of related technologies, or the insistence on supporting the business demands of operators, SingleRAN The emergence of Pro has undoubtedly added the best footnote for this.
