【摘要】 基于XML(可扩展标记语言)脚本的增值业务解释器有助于向用户提供可定制的个性化业务.基于XML描述电信业务而定义的XMLschema(XML模式)与电信业务状态转移进程的等价性说明,可以用基于XML面向电信领域的脚本描述电信业务,在此基础上阐明了基于XML脚本的业务解释器的基本原理,详述了基于状态模式设计XML脚本业务解释器的基本框架,分析了业务脚本的解释过程,并着重从可扩展性和执行效率2个方面说明实现业务解释器时采用的关键技术.更多还原

【Abstract】 The value-added service interpreter based on the XML(extensible markup language) can promote the customized individual services to the subscriber. According to the equivalence between the transition process of communication state and the XML schema describing the service in the telecommunication, the domain-oriented XML (language) can describe telecommunication services. Based on this, the service interpre-ter’s principal is introduced and its base framework is designed according to the state pattern, then the process of the service scripts is illustrated. The key technologies from point of view of scalability and efficiency of the service interpreter are explained.更多还原
