【摘要】 文中分析了国内3G产业发展的现状,在此基础上提出新的适合3G通信标准的3G智能卡USIM COS的系统解决方案。该方案采用适合3GCOS软件开发的半层次体系结构模型,并在模型中对各功能模块进行了详细划分;采用中断调度技术对系统的主调度流程进行了设计,最后结合半层次体系结构模型,给出微内核设计的覆盖模型方案,从而大大增强了3GCOS对3G网络的适应性和对不同硬件平台的兼容性。更多还原

【Abstract】 Through analysing the 3G industrial development in China, a new 3G USIM COS system solution suitable for 3G communication standard is proposed. This scheme uses three-level architecture model for the development of software 3GCOS,and the functional modules in the model are divided in detail. It uses interrupt scheduling technology to design the system’s main scheduling process. And finally a coverage model scheme about micro-kernel design is given,thus greatly strengthening the the adaptability of 3GCOS to 3G network and the compatibility to different hardware platform.更多还原
