The Research And Implement Of PRBT Call Processing System In IP-Based Network

At present, with the development of IP technology, an increasing number of telecommunication services are running in the IP Network. In the future, next generation network (NGN) will be based on IP. Now, PRBT Business System based on IP in China has been actively developed. PRBT Business System as the core of the PRBT platform, includes two parts: PRBT Call Processing System and PRBT Auxiliary System. Call Processing System mainly control the process of user's call, and help to play audio to users. Auxiliary Systems mainly complete the user information management, accounting management, group management and so on.In this paper, we talked about the implement of PRBT Call Processing System. Author designed the Call Processing System based on IP for Henan Mobile Ltd. The paper includes the following:First, the paper describes the importance of developing the PRBT Call Processing System in IP-Based network.Second, analyzing the functions of PRBT Call Processing System, the call process and signal process. In addition, we also discuss about how to play the ring sound to users.Third, the paper describes the functions of PRBT Call Processing System, analyzes the design pattern, definition of and functions of each module, structure of the PRBT Call Processing System. In addition, we also analyze the key technologies, including message transportation, signal processing and call processing.Fourth, describing the design and implement of PRBT Call Processing System in IP-Based network, including the various parts of the modules to achieve specific. The whole PRBT System, includes Call Processing module, Signaling Processing module, Message Transportation Control module, and Database Agent module. Call Processing module is responsible for the completion of the logic control of PRBT call functions. The author is mainly responsible for the design and implementation of this module.PRBT Call Processing System in the PRBT Business System plays a central role. It is useful and realistic to study the significance and the implement of it.
