Telecom Real-time Billing System Design And Realization

Recent years, with the rapid development of China's telecommunication industry, the communications business all appear rapid growth, and new business varieties and new service form has introduced, and old telecom business processing mode of charging from system to technology cannot adapt to the current situation needs more and more, even in a certain extent have restrictions and hindered the development of the business. Business expansion, the number of user expansion will result in the telecom industry development, the great business requirements also will promote a large software provider of business to participate in the telecom. How to realize the traditional telecom billing system to new comprehensive business and real-time pricing system, the transition of the success of the safety, how in numerous billing system of software to make reasonable, the right choice, and how to realize the pricing standard of unity and standardization, real-time, has become the current telecom billing system in the process of the development of an important problem facing.This topic is in the Unix operating system under the environment of timing, the latest data from the switch to download to download, real-time data obtained in view of the different switches for code system, and then the transformation conversion of data, according to pricing row heavy again principle for a pricing and secondary pricing and will last a data inventory added to database so that other procedure call. This topic is in the Unix system of telecom real-time billing system to complete the simulation and discussed, and form a basic model of the system. Design into consideration on the stability of the system operation period, fault tolerance, through the reasonable design of each program communication between mechanisms, to coordinate the whole the operation of the system. Here the communication mechanism used a named pipe, IPC (XSI message queues, and sharing storage, the magnitude of the signal), signal, etc. Use the real time monitoring to the timely discovery system is running all sorts of erroneous, use log to record the progress and operation condition, thus achieved the system to better and more healthy operation purpose. In the design of the module in heavy, we also adopted the heap sort, so as to improve the efficiency of the processing of the communication detail records.But, the system still has some flaws. For example, not on the system can accommodate flow of data cap the assessment, and that system in unit of time can handle the data. There is a large amount of data, face, there is no. reliable measures to ensure that the system can be smooth handle more than memory size of data files.To this, the system also has more content to deal with:(1) Providing to accidental huge amounts of data communication detail records document support, such as the temporary files to break up a big communication detail records document. This is not enough to consider in memory down a single file.(2) Providing better row heavy plan to make the treatment efficiency, so as to improve further improve on high data flow good support. Consider the efficiency for sacrifice space here get better time benefit.(3) Improving the system processing, on the system renewal before little extended. Such as perfect communication detail records, the introduction of customer service provided support to the system, user support. The inquires communication detail recordsThis design by hardware, only on environmental restrictions of existing communication detail records data processing, the system of all executable file and data documents are unified on a master folder, and then the folder, such as several small points of the second chapter requirement analysis. System is running as long as ready to data, operation procedure, the Lord of the program will run many processing programs to deal with data, and running monitoring procedures and log program to monitor and record processes to ensure the stable operation of the system.Because the system applied in the background, so not much host user interface and not very friendly, in the capture several sample files and monitoring among sample interface for describing the realization process.
