With the rapid development of information and communication technology and the growing communication needs of the people, as the national communications infrastructure, an important part of the telecommunications network, Internet, radio and television networks Dengjun to the critical period of development, integration and development have become telecommunications network, the Internet and broadcast networks the main theme of development. However, understanding the meaning of the integration more broadly, including not only communication and information technology (ICT) integration, but also the fixed telecommunications network and mobile telecommunications network integration, but also telecommunications networks, Internet, broadcast television networks in the triple play. Triple play specifically refers to telecommunication networks, Internet and broadcast television networks in the technical convergence of three networks; at the network level resource sharing and interoperability; at the operational level and have focused on infiltration and cross each other; the industry level for information service, the industry, breaking their own boundaries for gradual integration; the regulatory level, a clear relationship between the parties and functions, build new information services regulatory system.
Face the triple play of development trends and goals, present, telecommunications networks, Internet and broadcast television networks are evolving to next generation: telecommunication network operators in the business and network development driven comprehensive business to be able to carry NGN Evolution ; the Internet more by the software, IT and other technology-driven evolution to the more secure the NGI; broadcast television network for digital TV will be the adoption of next generation digital broadcast television network evolution. As the telecommunications network, the Internet and broadcast television networks based on different existing networks, as well as in operations, business model, service quality, safety, regulatory differences, in the near future three networks will be in accordance with their respective problems and continue to set the development direction relatively independent development of the short term, difficult to achieve integration.
From the perspective of the evolution of the telecommunications network, the current IP Multimedia Subsystem (IMS) is a platform for telecommunications service integration to achieve the goal to design, from traditional telecommunications services, particularly the evolution of voice services to consider in a kinds of networks evolve. Triple play of development in the face of demand, IMS need for structural adjustment and improved features, such as the open Internet, the success of user involvement is the source of the essential characteristics of the Internet is, how the user IMS system to ensure open participation and innovation, how to find a balance between regulation and opening up, how to attract the Internet and broadcast networks from non-IMS services, IMS follow-up studies are needed to consider.
The bearer network layer and, although the three are integrated does not mean an alternative to the other two network bearer network, but the face of the network integration business for ways to reduce costs, optimize network resources and improve utilization of network resources, increase network operation and maintenance capability will be the focus of future research. ITU-T NGN Framework has clearly a bearer network's important position and role, and started a new type of bearer network for triple play technology research?? Future packet-switched network (FPBN, FuturePacketBasedNetwork), China in this area a leading position, has completed a number of leading ITU-T recommendation.
Therefore, in the triple play of development trends, telecommunications networks and telecom services to achieve the transformation will be a long-term work. Existing technology systems (such as IMS/IPv6) and the technical direction (such as FMC) is the initial stage of this evolution, the face of the needs of information society, national communications infrastructure will face deep-level adjustment.
