The Design And Implementation Of Tariff System For Program Controlled Switchboard

At present, there are internal private communications networks in many of the large domestic industries'systems. The digital program-controlled switchboards are used to provide inside telephone, Local and long distance calls service. There are also some departments also provide IP telephone, ADSL and some Internet broadband access and other value-added business services. The digital program-controlled switches users can provide integrated services telecommunication services. It has become an important task of telephone management department to realize the digital program-controlled switches integrated management of the business within the industry. Therefore, we can make sure that the business management and services will be developed well and the level of telecommunications services will be improved and enhanced.Guangzhou Port is the largest comprehensive hub port in South China. It keeps increasing in cargo volume owing to its fast growing hinterlands'economy. The communications network in Guangzhou Port also experienced a process expanded and improved gradually from backward to advance. It provides a reliable communication support for the development of Guangzhou PortWith the constant development of Guangzhou Port Group Company, there is a higher demand on the Communicate specifically Netcom. The billing systems also demand a higher accuracy and higher real-time.The billing systems of Guangzhou Port Group Company include billing processing subsystem and accounts processing subsystemThe billing processing subsystem deals with the billing data collection process and the grant price process.(1) The tasks of billing data collection deal with the collection of raw data and information from the switch, and the corresponding error test, format conversion and other preprocessing. The results generated in this state can only record the situation of the network users. It does not reflect the charges of the network users.(2)Grant price refers to accurate the cost of the network users in accordance with established principles and rules.The accounts processing subsystem can fully meet the needs of customers of the accounts to support flexible, multi-channel charging capabilities. It can also provide the personalized and detailed bill of the customers. Besides, it also supports a variety of bills distributed form. It can provide a quick response to the market changes, to facilitate support the new brand, the new tariff packages and the other new service means.From the perspective of the design, development and application the system, it has the following characteristics:1. The application of the open modular designThe whole system uses an open modular design, it can be easily added some new business capabilities for system expansion. The users can realize the system expansion and restructuring by increasing the application module according to their growing business needs. In this process, the size of the original premise of the system needn't to be enlarged. There are the flexible options to decide the system configuration on a small scale or a large scale. Therefore, this system has excellent scalability.2. The application of the components, software bus technologyThe software bus technology used by this system is a new information integration technology, which aims to improve the system flexibility. The association of the business established on the information, rather than the function. All of the system functions maintain their relative independence of each other. The existence of the functional components does not rely on the other functional components, but on the data. The function service distribute on the line to realize the registration and storage. It can also provide a unified directory service. All the services used by a unified management. The functional modules can be added and removed to realize the "hot swap." This enhances the system's distributed processing capabilities, which make the system has the strong expansion capability and high maintainability features.3.The application of the technology of the object-orientedThe object-oriented technology will apply to all of the aspects of this system. The object-oriented approach has deepened into the field of computer software and all of the other branches, and even including the computer architecture and artificial intelligence.
