At the beginning of 2 1 century, the Okinawa Charter of the Global Information Society held by the Group of Eight in Okinawa held that "information and communication technology is one of the most powerful driving forces for social development in 2 1 century, and will soon become an important driving force for world economic growth." In fact, the understanding of ICT in the information and communication industry is not uniform. As a technology, it is generally understood that ICT can not only provide various services based on broadband and high-speed communication networks, but also transmit and enjoy information. It is also a general intelligent tool. As for how much business there will be and how smart this tool will be, the current concept is still very vague. Triple play is only a foundation and prelude of ICT, and IPTV and mobile TV are probably just the tip of the iceberg. For fixed-line operators who have sounded the horn of transformation, ICT is now more regarded as a service provided to customers. This service is the combination and blending of IT (information industry) and CT (communication industry), and the communication industry, electronic information industry, Internet and media industry will all be integrated within the scope of ICT. Fixed network operators such as China Telecom provide customers with one-stop ICT services, including comprehensive services, outsourcing services, professional services, knowledge services and software development services. In fact, ICT services not only provide enterprise customers with solutions for line construction and network architecture, but also reduce the burden of enterprises in establishing applications, system upgrades, operation and maintenance, security and other aspects, and save the operating costs of enterprises, so they are welcomed by enterprise users. At present, the intersection of IT and CT is mainly reflected in the construction of IT enterprises' support system for operators. It is worth mentioning that BOSS (Business Operation Support System), mobile is called BOSS, and China Telecom and China Unicom are called BSS.
