In view of the diverse and personalized information needs of users, China Mobile has established the information orientation: adhere to the mobile orientation and adhere to the terminal orientation. In the field of industry informatization, the development idea of China Mobile is: facing two kinds of target customers, adopting two modes to promote informatization. The first is to deploy mobile proxy server (MAS) applications for group customers with high information level. This kind of customers generally have Intranet and independent database, all kinds of application systems are relatively complete, and there are specialized IT departments and personnel. MAS applications can quickly and effectively couple the existing IT systems on the customer side of the group, provide multi-service standard interfaces, and connect with the mobile network to realize information mobility. The second is to provide application hosting (ADC) services for customers in industries with low informatization. Most of these customers have no Intranet, most application systems have not been built, and there are no specialized IT departments and personnel. The realization of "selling for rent" ADC services can provide "one-stop" solutions and comprehensive information technology support.
According to the strategic focus of national informatization development, China Mobile pays attention to social hotspots and vigorously expands the application of key industries. At present, it has achieved remarkable results in industries and fields such as agriculture, rural areas and farmers, social and personal safety, financial securities, education and police. For example, in the field of "agriculture, countryside and farmers", under the guidance of the Ministry of Agriculture, China Mobile has carried out the business of "Nongxintong", paying attention to rural government management, agricultural production and farmers' livelihood. At present, 3/kloc-0 provincial companies have signed comprehensive cooperation agreements with 75 agricultural departments such as provincial agricultural bureaus and agricultural committees, 248 prefecture-level mobile companies have signed cooperation agreements with 342 prefecture-level agricultural departments, and the number of users of "Nongxintong" has reached 200. In the field of social and personal safety, it signed a cooperation agreement with the Ministry of Public Security to promote police communication and location alarm, and * * * formulated and issued the "Guidelines for Police Mobile Specification and Construction". At present, the number of police general users has reached 204,000. In the securities industry, the Caixintong Club was launched in cooperation with the China Securities Regulatory Commission, the Securities Industry Association and eight major brokers to carry out investor risk education. At present, it is piloted in three provinces and will be promoted nationwide in 10. In the financial industry, we have cooperated with more than ten national banks to promote the banking ICT business, and provided business solutions to meet the information needs of bank customers such as real-time financial information, mobile office of bank employees and production control through SMS, GPRS and other wireless access methods, helping banks save costs, improve efficiency and increase income. In terms of urban management, a new grid-based urban management model has been innovatively introduced, and urban management links have been jointly promoted with the Ministry of Construction. At present, 28 cities in Beijing, Shanghai, Yangzhou, Chengdu and other provinces 12 have signed cooperation agreements. In addition, China Mobile has achieved positive results in the application of mobile information technology in production safety, epidemic prevention and control, food safety, consumer safety, medical care, education and clean government education in party member.
