Technology development strategies of telecommunication networks in the backgroud of tri-network convergence

Tri-network convergence is a global trend in the development of information technology to accelerate three networks convergence. This paper introduces the concept of tri-network convergence, describes the network architecture, and analyzes the main technical features needed in the tri-network convergence. Then the paper puts forwards the development ideas of the telecommunications network in background of the tri-network convergence. A few of recommendations are proposed to telecommunication operators, that is, speeding up the development of the broadband access network, enhancing network capability to support broadcast and multicast services, improving the efficient delivery of vast amounts of video services, supporting a variety of integrated services, and strengthen network security and information security capabilities.
