The development and thinking of M2M: the big problem of resource integration needs to be broken
M2M (Machine-to-Machine) is a networked application and service centered on intelligent interaction of machine terminals. The broad definition of M2M also includes Man-to-Man and Man-to-Machine. From a definition point of view, M2M reflects a ubiquitous interconnection concept. The continuous development of communication technology and mobile internet technology enables the realization of the M2M technology concept. By embedding a wireless communication module inside the machine and using wireless communication as an access means, the user is provided with a comprehensive information solution to meet the user's data. Informatization needs in terms of acquisition, real-time monitoring and remote scheduling. It can be seen from the current development trend that M2M is the development trend and application of the future mobile Internet, and an important part of the Internet of Things. Therefore, it has received extensive attention in national policy orientation, key technology research and development, related standards promotion and industrialization promotion. In terms of policies, the Ministry of Industry and Information Technology's "Twelfth Five-Year Development Plan for the Internet of Things" clearly states that China has formed one of the largest M2M markets in the world. In the process of follow-up industry development, it is necessary to continue to promote M2M terminals. The improvement of manufacturing capabilities of communication modules, gateways, etc., promotes the development of operational services based on M2M. In terms of technology, the research and development of key technologies for M2M has been carried out simultaneously from multiple layers. 1) The research on the overall architecture of M2M is generally based on the improvement and improvement of the Internet of Things architecture, providing theoretical guidance for the overall environment construction of M2M; 2) The research on M2M terminal equipment mainly includes device abstract description, function expansion, communication module optimization and device identification. Identification and other work, the purpose is to enable M2M terminal equipment to operate independently and complete data interaction, providing underlying support for M2M applications; 3) research on access networks based on communication technology, sensor network technology and mobile Internet technology, etc. Committed to providing network access for M2M devices anytime and anywhere; 4) For the ubiquitous heterogeneity (heterogeneous devices, heterogeneous networks, heterogeneous applications) existing in the M2M environment, the development of middleware can provide different protocols between The conversion interface enables compatibility and interconnection between heterogeneous systems. In terms of standards, CCSA completed the M2M business research report as early as 2009. In 2012, the Ministry of Industry and Information Technology issued the “M2M Business Overall Technical Requirements†series of standards, which stipulated the business function requirements and system functions of the communication network when providing M2M services. Technical requirements such as architecture, system logic function modules, billing requirements, interface requirements, and business security. The seven ICT industry standardization organizations (ETSI, TIA, ATIS, CCSA, ARIB, TTC, TTA) in Europe, the United States, China, Japan and Korea as the sponsoring organizations signed a partnership agreement in the United States on July 24, 2012, which was formally established. OneM2M, the international standardization organization for the Internet of Things. OneM2M focuses on the development of M2M standards and standardizes M2M applications in various industries to promote the sustainable and healthy development of the international M2M industry. In terms of industry, according to the 2014 White Paper of the Ministry of Industry and Information Technology, by the end of 2013, the number of global M2M connections reached 195 million, with a compound annual growth rate of 38%. Related forecasts indicate that by 2020, the number of M2M connections will exceed 2 billion, and the revenue of operators M2M will reach 1.2 trillion US dollars. Therefore, telecom operators are still the main promoters of M2M. 428 mobile operators around the world provide M2M services, including France Orange, Deutsche Telekom, AT&T and other companies. China's M2M subscribers rank first in the world, and China Mobile M2M has become the world's largest M2M operator. With the comprehensive development of M2M technology, some related issues deserve our deep thinking. Based on the National Internet of Things (IoT) logo management public service platform, China Internet Network Information Center points out that the key issue in the development of M2M today is to form an efficient and interoperable overall environment. Existing M2M applications are mostly vertical industry applications, forming more and more applications and information islands, without maximizing the use of existing resources, and the traditional loose interconnection method makes M2M resource integration a major problem. Therefore, a unified M2M platform should be established to achieve efficient integration between resources and applications, and based on this, a new M2M application model will be created. At the same time, the unified M2M platform cannot be easily promoted. Different from traditional Internet resources, the resources involved in M2M applications emphasize the correspondence with the real physical world, and M2M applications are also closely related to real production and life, such as smart grid, security monitoring, traffic supervision, smart home and smart medical. Wait. Due to various factors such as national sovereignty, commercial interests, and technical protection, each participant in the M2M application hopes that the resources provided have independent management and control authority. Therefore, the design of the M2M architecture and the establishment of a unified platform must consider the autonomy requirements. Establishing an M2M application environment with equal interoperability is an urgent problem that needs to be solved at present, and is also a prerequisite for the smooth promotion of the M2M industry. Although OneM2M is conducting technical research on standardization to try to solve the problem of compatibility and interoperability, it ignores the issue of autonomy. Analogous to the current domain name service (DNS) system, the interconnection between countries must pass the domain name root node managed by ICANN, which limits the self-management of China's network to some extent. Therefore, in the early stage of M2M technology and standardization work, China should actively participate in and promote efficient and autonomous solutions. On the one hand, improve China's right to speak in the field of M2M research and standardization; on the other hand, promote the establishment of an efficient M2M technology framework and independently develop China's M2M industry.
