【摘要】：随着移动3G网络技术的成熟，以及4G移动网络LTE的逐步建设，无线数据卡终端产品越来越受到广大消费者们的喜爱。无线数据卡设备能不能给用户提供良好的体验，已成为项目研发的关键因素。本文以基于MDM9200平台的无线数据卡项目为背景，针对目前无线数据卡自启动子系统所存在的缺陷，进行项目需求分析。对项目涉及到的高通AT命令、WDF过滤驱动、HS-USB协议、SCSI和BULK-ONLY协议等理论知识进行介绍。在此基础上，本文设计了新型自启动子系统体系结构。然后对子系统结构进行模块划分并对模块进行详细设计与实现，最终实现了改进后的自启动子系统。该子系统在软硬件结构上都优于原来的子系统，，解决了目前项目存在的缺陷。本文最后将设计的自启动子系统用于无线数据卡进行测试，证明实现了无线数据卡设备的自启动功能，改善了用户体验并满足了设备生产商的需求。该项目现已经研发成功，并且投入欧美市场。
[Abstract]:With the maturity of mobile 3G network technology and the gradual construction of 4G mobile network LTE. Wireless data card terminal products are more and more popular among consumers. Whether wireless data card equipment can provide users with a good experience has become a key factor in project research and development. This paper takes the wireless data card project based on MDM9200 platform as the background, aiming at the shortcomings of the wireless data card self-starting subsystem. To carry out project requirement analysis. The high quality AT command and WDF filter driver involved in the project are analyzed and the HS-USB protocol is introduced. SCSI and BULK-ONLY protocol and other theoretical knowledge are introduced. On this basis. In this paper, we design a new self-starting subsystem architecture, and then divide the subsystem structure into modules and design and implement the modules in detail. Finally, the improved self-start subsystem is implemented, which is superior to the original subsystem in hardware and software structure, and solves the defects of the current project. At the end of this paper, the self-start subsystem is used to test the wireless data card, and it is proved that the self-start function of the wireless data card device is realized. Improved user experience and met the needs of equipment manufacturers. The project has been developed successfully and is available in Europe and the United States.
