摘　　要：针对基于面向服务架构的移动信息服务平台,研究了移动工作流的结构模型,分析了流程设计中的Web服务接口及其消息驱动的协同机制.移动工作流主要依赖SMS和MMS协议发起同外部进行通信和服务调用.当用户发起某一事项申请时,工作流引擎实例化流程,按照每一个活动中协同规则调用服务来完成该活动的任务.由于流程节点之间的流转体现出多种协同关系,在进行逻辑规则和时间规则分类的基础上,提出了基于业务流程执行语言BPEL协同规则的描述方法.以申请开放实验项目协同流程为例,涉及多种人员角色,利用移动短消息的模式驱动流程的流转,利用基于BPEL描述的服务协同规则进行了实现,取得了良好的效果.表明所提出的方法有利于简化移动服务平台的系统集成,缩短系统设计周期.For the mobile information platform based on service oriented architecture,the mobile workflow model is presented.The Web service interfaces and the message-driven cooperation mechanism among processes are analyzed in mobile workflow design.When a user applies for a certain transaction mainly depending on SMS/MMS protocols,the mobile workflow engine initializes the corresponding process instance,and invokes the involved services according to the cooperation rules.Since the relationships among business flow nodes are diverse,the rules are categorized into logical rules and time rules,and then the description method based on business process execution language is presented.Furthermore,the business process of the open laboratory application project is studied as a practical case.The workflow involves multiple roles and is driven by mobile messages.The service cooperation described by BPEL is implemented and good results are achieved.Thus,the proposed method can simplify the mobile workflow design and shorten the design cycle time.
