Upgrading Of The Operating And Management Information System For Air Traffic Management Of CAAC

With Phase I of the operating and management information system for air traffic management was completed successfully, the integration of entire information on air traffic management of Civil Aviation Administration of China (CAAC) has been established gradually. The system was based on a high-speed network that had made a close connection between the Air Traffic Management Bureau of CAAC and the Regional Air Traffic Management Bureaus. As going to greater depth of Integration of the National Air Traffic Controllers, the Air Traffic Management Sub-Bureaus (or Stations) that belong to Regional Air Traffic Management Bureaus, also has exigent expectation to join and use the operating and management information system. In the six years of the system running, not only because the volume of the air traffic control operations increase continually, but also the system itself has urgent need to increase and optimize the bandwidth of the backbone network, and upgrade the application softwares. Considering the trends of information technology modernization and the issues facing by the current air traffic management system, upgrading of the current system is imperative.In Phase I, Air Traffic Management Bureau of CAAC as a national center for air traffic management in China has been established successfully. A high-speed network with application software running on it that based on Asynchronous Transfer Mode communication technologies has connected seven Regional Air Traffic Management Bureaus. In Phase II, the aim will be to extend the network coverage, and construct a high-speed network that could link 36 Air Traffic Management Sub-Bureaus (Stations). The application software will also be extended to integrate information resources of the Regional Air Traffic Management Bureaus and the Air Traffic Management Sub-Bureaus (Stations). So that the network could connect all the three level of administration bureau, sub-bureau or stations, i.e., the Air Traffic Management Bureau of CAAC, the Regional Air Traffic Management Bureaus, and the Air Traffic Management Sub-Bureaus (Stations). The system will access the existing branch service systems, and provide real-time data for the entire system. The Air Traffic Management Sub-Bureaus (Stations) will also obtain required information through the system.Based on the Phase I system, combined with service requirements and development trends, this thesis designs the upgrading scheme for the second phase of the operating and management information system for air traffic management and makes a detailed plan on how to incorporate the 36 Air Traffic Management Sub-Bureaus (Stations) into the overall system smoothly. This thesis is divided into five chapters:Chapter I includes a brief introduction of the status of the Phase I system, the overall network structure of Phase II, and the significance of the upgrading. Chapter II, titled as Asynchronous Transfer Mode for Broadband Communications, introduces the basic concepts of asynchronous transfer mode, the network performance, broadband switching technology, and traffic control and congestion control. Chapter III, the system design for upgrading of the operating and management system for air traffic management, describes the overall system architecture, the internal logic structure, basic network platform, network information security system, application system functions, selection of hardware and software platforms, and equipment configuration. Chapter IV, technology network system solutions, discusses the network system design, the upgrade actualize of network structure and so on. Chapter V, the conclusions, summarizes the overall technical solution and project implemenatation of the PhaseⅡsystem.
