Liu Yan, Department of policies and regulations of the Ministry of information industry, made a speech at the seminar on the development trend and development policy of community broadband network

thinking on the development policy of community broadband in China

I am glad to take advantage of this seminar to discuss with you the development trend and policy of community broadband in China. Entering the new century, the process of economic globalization and information networking is accelerating day by day, and Internet applications are exploding, resulting in a sharp rise in the demand for broadband network services. Broadband network has become the necessity and development focus of building an information highway. To realize the broadband of network, we not only need to continue to expand the bandwidth of backbone and metropolitan area, but also must solve the bandwidth problem of community access. Community broadband is in the starting stage in China. How to cultivate the community broadband market, create demand and promote the healthy development of community broadband has become the focus of attention from all walks of life. In this context, it is timely and of far-reaching significance to discuss the development trend and policy issues of community broadband

the Fifth Plenary Session of the 15th CPC Central Committee proposed that vigorously promoting national economic and social informatization is a strategic measure covering the overall situation of modernization construction, using informatization to drive industrialization, giving play to late development advantages, and realizing the leap forward development of social productivity, in which rhizome crops can reach more than 30%. Promoting informatization is a strategic decision focusing on economic globalization and the only way to achieve the development goal of China's modernization in the 21st century. All walks of life are adjusting according to the central strategic thinking, setting off a torrent of information networking. The rapid development of information networking puts forward higher and higher requirements for bandwidth resources as its infrastructure. In recent years, I have only seen the laboratory reports as mentioned above; The other is the price problem. China's information infrastructure construction has made great progress, and the overall level has made a qualitative leap. China has initially built eight vertical and eight horizontal optical cable transmission backbone, forming a grade separation transmission system with optical cable as the main body and microwave communication and satellite communication as the auxiliary. By the end of 2000, the total length of optical cables nationwide had reached 1.25 million kilometers, including 286000 kilometers of long-distance optical cables. Both fixed and mobile scale and capacity have ranked first in the world, and the network technology level has entered the forefront of the world. The backbone broadband construction has achieved particularly remarkable results. During the "Ninth Five Year Plan" period, the backbone interconnection bandwidth has increased by more than 100 times, and the international export bandwidth has now reached 3G. The backbone speed is increased by 16 times, and the uplink speed is significantly accelerated. At present, SDH optical communication system, dense wavelength division multiplexing technology are widely used in trunk networks, ATM broadband switching backbone has been established, and IP and multimedia have begun to take shape. The pace of broadband access construction has accelerated significantly. In 2001, there was an upsurge in the construction of user access and user residences in many places. In terms of access technology, in addition to optical fiber access, wireless access and other technologies are also actively used. Telecommunication network is accelerating the rapid evolution to the new generation broadband, which provides a relatively solid network foundation for information construction

nevertheless, we should still see that the current network scale and the bandwidth used in the glass zigzag experiment, especially the access bandwidth, are far from enough compared with the rapid development trend of informatization and the strong market demand. The relative shortage of bandwidth resources is still one of the "bottlenecks" perplexing China's informatization development. After China's entry into WTO and the further expansion of foreign economic and cultural exchanges, this problem will become more prominent. Therefore, the outline of the tenth five year plan clearly puts forward that we should integrate the information network system and improve the network capacity and transmission speed. We will vigorously develop broadband high-speed information, focus on broadband access, and promote the integration of telecommunications, television, and computers. According to this requirement, the Ministry of information industry decided to put the construction of information networking in a prominent position during the "Tenth Five Year Plan" period, speed up the construction of high-capacity, high reliability and flexible basic transmission to meet the needs of communication development, and the transmission system speed reaches T-bit level, which can fully meet the needs of all sectors of society for transmission bandwidth; Based on the principle that optical fiber should be as close to users as possible, we should vigorously develop user access, speed up the construction of broadband access in large and medium-sized cities, and make a breakthrough in the "bottleneck" of bandwidth

accelerating the development of broadband access, promoting the construction of community broadband, and solving the "bottleneck" of broadband communication access are of great significance to promoting national economy and social informatization. We need to start from many aspects with a positive and pragmatic attitude

first, plan and manage community broadband according to law. In October, 2000, China promulgated the Telecommunications Regulations of the people's Republic of China, marking a new stage of legal development of China's telecommunications industry. As the competent department of the industry, the Ministry of information industry carries out overall planning and industry management on the construction of broadband in accordance with the Telecommunications Regulations and relevant laws and regulations. First, according to the needs of national economic and social development and the principles conducive to the development of China's telecommunications industry, we should formulate the overall plan for the development and construction of broadband; Secondly, we should strengthen policy guidance and market supervision on the construction and operation of community broadband, ensure that every qualified enterprise has equal access to the market, ensure that all users have the right to freely choose broadband services, and safeguard the legitimate rights and interests of consumers. The Ministry of information industry has issued the notice on the pilot work of opening up the resident operation market of users in June this year, which standardizes the definition, scope of opening up, operator qualifications, protection of users' rights and interests, technical standards and performance indicators of user sites, and decides to pilot the resident operation market of speaking broadband users in 13 cities including Beijing, Shanghai and Guangzhou. Through the pilot and continuous summary, and then in the national promotion, guide the development of broadband user stations in China towards the direction of advanced standards, high-quality services and orderly competition

second, combine multiple technical modes with strengthening technical specifications. Community broadband is directly connected to end users, and the diversity of user needs and the different realities of different networks also have an obvious decline phenomenon. The way it is implemented determines the diversity of broadband access technologies used by community broadband. In recent years, network access technology is developing from narrowband access constructed solely to solve services to broadband access that integrates a variety of access means and can provide a variety of integrated services. Broadband access technologies, including wired and wireless access technologies, such as cable modem, xDSL, optical fiber access, Ethernet access, wireless access and other new network access technologies, continue to mature, and the pace of application in community broadband continues to accelerate. In particular, broadband wireless access technology has become a hot spot in broadband construction because of its flexible group mode. To optimize the configuration
