中文摘要: 在3G IMS 系统中，在线实时计费是非常重要的一种计费单元，而费率功能模块是该计费系统的核心。由于3G IMS 计费系统处理的是多种复杂应用与服务混合的计费内容，所以对费率功能模块的设计与实现提出了较高的要求，并成为当前的研究热点之一。在分析IMS 在线计费系统的基础之上，对复杂应用和服务进行了研究，提出了费率功能模块的针对价格和多种价目请求的设计模型并加以实现，给出了该模型的实现要点，对其中的价目请求模块进行了详细说明。最后，对使用以该费率模块为基础的在线计费系统的IPTV 业务进行了测试，测试结果表明该费率功能模块满足复杂计费请求需要，设计合理可行。
Abstract:In the system of 3G IMS, online charging is an important module for charging. The rating function is a core founction of online charging system. Because 3GPP IMS charging system has to deal with complex charing intent with many services and applications, there is a high standard for desingning and implementing a rating function module. It is a hotpoint for studying rating funtion. This article suggests and realizes a model for rating funtion based on analyzing online charging system, defines complex application and service. Also, it specifies the tariff request module in rating function. At last, we test IPTV service based on the online charging system which uses this rating funtion, the testing result proves the model is feasible.
