摘　　要：本文首先介绍了一种在移动增值业务开发中被广泛应用的统一消息接口模型,简要描述了该模型的整体结构和基本功能,以及它在增值业务开发中所处的位置。在介绍模型时,为便于讨论,本文将该模型逻辑上划分为了4层结构,并用逻辑结构图做出说明,随后在总体上阐述了模型的工作机制和消息的处理流程。在此基础上,本文对模型在结构和功能上不合理或不完善之处进行了探讨,随后重点讨论了本文的改进方案,包括消息缓冲区结构的改造(重组缓冲区)、重发策略的修改、流量控制策略的完善(增加滑动窗口功能等)、缓冲区警戒及告警(增加溢出警戒、告警功能和灵活的告警策略,收发控制等),并且阐述了这种改进所具有的现实意义。This paper describes UMI（Unified Messaging Interface）, which is a kind of messaging models and has been widely used in development of mobile value-added service. Then we give a brief description of this model about the overall structure and basic functions, following by an introduction of this model＇s location in the mobile value-added service development. In order to facilitate discussion, this model is logically divided into four function layers illustrated by the logical structure graph. Then, this paper generally describes the working mechanism and messaging process. On this basis, this paper analyzes the unreasonable structure and inadequate functions of this messaging model. Then we focus on the improvement programs, including the transformation of message buffer （re-organization of buffer）, improvement of flow control strategy （such as sliding windows）, buffer security reinforcement （overflow alert, alarm, flexible alarm strategy）. Finally, we elaborate the significance of this improvement.
