Abstract: In streaming media applications,prepaid services require the billing system to provide real time billing and service control.After analyzing the disadvantage of existing billing schemes,design a Streaming Media Online Charging System to support prepaid services,introduce the online charging process of a typical streaming media service-VoD service,and then provide an optimization scheme to improve the overall performance of the system by adopting main memory database.The experiment indicates that the system designed in this paper can meet the real-time billing requirements of the streaming media application effectively,and can be used in streaming media circumstance easily.
