摘　　要：为了克服Parlaywebservices存在的扩展性差等缺陷,提出了一种基于开放网格服务体系(OGSA)的新的Parlay/OSA业务架构——Parlaygridservices,通过将Parlay与OGSA融合并对外提供webservice接口,充分利用了OGSA、webservices和Parlay/OSA三者的优点,支持异步操作、生命周期管理、有状态服务和多层服务集成,具有很好的扩展性.讨论了基于Parlaygridservices的下一代网络环境中的业务融合问题.To overcome the limitations of Parlay web services, such as inextensible, a new Parlay/OSA service architecture based on open grid services architecture（OGSA）, named Parlay grid services, was proposed, with which, Parlay was integrated with OGSA to provide the interfaces through web service, which inherits those advantages from OGSA, web services and Parlay/OSA, and support asynchronous operations, lifetime management,stateful service and multilayer service integration, as well as excellent extensibility. In the final, the services convergence based on new Parlay grid services architecture in next generation network environment was discussed.
