Parlay/OSA与Web服务的技术融合及其商业应用

在传统电信网络中,电信业务及其应用主要通过智能网等集中式智能网络技术实现,通常部署在各电信运营商通信网络内部。近年来,随着互联网的飞速发展以及人们对新型业务需求的不断增加,电信运营商必须将其业务部署与承载网络分开,以向更多业务提供商开放其通信网络,让第三方能够以可管理、可计费、安全的方式参与到电信业务的开发过程中。正是这种需求的刺激,推动了Parlay/OSA规范的制定和发展。文章从体系架构角度,分析Parlay/开放业务访问(OSA)和Web服务(Service)两种技术,比较两者在目标功能实现及其与外部应用交互方式上的异同点,并基于此提出了两种技术融合路线,最后介绍3种典型的ParlayWebService商业应用模型。

Technical Convergence of Parlay / OSA and Web Services and Its Business Application

In traditional telecommunications networks, telecomm services and applications are primarily implemented by means of IN (intelligent network) technology through a centralized IN which is deployed as a part of the operator's telecom network. In recent years, along with the rapid development of Internet and the substantial increase of new application demand, operators have to separate application deployment from the carrier network so as to open up their telecom networks to more service providers and enable them to join the telecom service development in a secure, manageable and billable way. This is exactly the demand that stimulated and driven the establishment and development of Parlay/OSA. In this paper, we provide a comparison between Parlay/OSA and Web Services from the architectural point of view. The analysis mainly includes the similarities and differences in the realization of targeted function and interaction mode between applications and servers. Based on that, we put forward two kinds of technical convergence scenarios. Finally three kinds of typical business application models of Parlay Web Services are introduced.
