Abstract

The development of value added services is currently still very time and cost consuming. The need for specific user generated and in particular business-to-business services demands for efficient service development methods. This paper presents a service creation environment that supports the application developer to compose a service based on reusable components and to describe the business process through a control logic. For the service description a language that has been optimized for business processes is suggested: the Business Process Execution Language (BPEL).  However, BPEL has not been developed for control of specific, in particular real time, communication services in heterogeneous networks.Therefore the paper presents a parser translating the business process description into Java code and supporting the deployment of the service in a service execution environment based on JAIN SLEE. The provided elementary communication Service Components hide the underlying heterogeneous communication networks. Thereby the developer does not need any detailed knowledge of communication protocols and is able to focus on the application logic instead. This leads to new opportunities for rapid and efficient service creation using a new Service Creation Environment (SCE) with higher level of abstraction and automated service generation.
TeamCom:下一代网络的服务创建平台
增值服务的发展目前仍然非常耗时和耗费成本。需要特定的用户生成的服务,特别是企业对企业的服务,需要有效的服务开发方法。本文提供了一个服务创建环境,该环境支持应用程序开发人员基于可重用组件组合服务,并通过控制逻辑描述业务流程。对于服务描述,建议使用针对业务流程进行了优化的语言:业务流程执行语言(BPEL)。然而,BPEL并不是为控制异构网络中的特定(特别是实时)通信服务而开发的。因此,本文提出了一个解析器,将业务流程描述转换为Java代码,并支持在基于JAIN SLEE的服务执行环境中部署服务。所提供的基本通信服务组件隐藏了底层的异构通信网络。因此,开发人员不需要任何通信协议的详细知识,而是能够专注于应用程序逻辑。这为使用具有更高抽象级别和自动化服务生成的新服务创建环境(SCE)快速高效地创建服务提供了新的机会。
