介绍了第三代移动通信网络中的业务开发技术-Parlay以及开放式接口API,详细分析了该技术的计费业务提供机制。在分析现有计费模式的不足的基础上,描述了内容计费的产生、需求及发展,介绍相关标准。重点研究了Parlay API规范中计费SCF(Service Capability Feature)在内容计费的3G计费平台中所提供的计费能力。针对WAP网页浏览业务,使用UML设计了基于流量的计费业务,给出了数据流分析示意图和计费流程。
Introduced the business development technology in the third generation of mobile communication network, Parlay and open interface API, and analyzed the billing service provision mechanism of the technology in detail. Based on the analysis of the shortcomings of the existing billing model, this paper describes the generation, demand and development of content charging and introduces relevant standards. The research focuses on the charging capabilities provided by the Charging SCF (Service Capability Feature) in the 3G charging platform for content charging in the Parlay API specification. For WAP web browsing business, UML was used to design the traffic-based billing service, and a schematic diagram of data flow analysis and billing process were given.
