Abstract

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.

Key words: Online Charging System, real-time billing, streaming media, Main Memory Database, Diameter Credit Control

摘要： 流媒体应用中，预付费业务向计费系统提出了实时计费和实时控制的要求。分析了流媒体应用中现有计费方案存在的不足，设计了一种支持实时计费的流媒体在线计费系统，介绍了流媒体典型业务的在线计费流程，并利用内存数据库技术优化了系统的实时处理性能。实验表明设计的在线计费系统能有效满足流媒体业务实时计费的要求，具有良好的实用性。
