【摘要】：隨著移動3G網(wǎng)絡(luò)技術(shù)的成熟，以及4G移動網(wǎng)絡(luò)LTE的逐步建設(shè)，無線數(shù)據(jù)卡終端產(chǎn)品越來越受到廣大消費者們的喜愛。無線數(shù)據(jù)卡設(shè)備能不能給用戶提供良好的體驗，已成為項目研發(fā)的關(guān)鍵因素。 本文以基于MDM9200平臺的無線數(shù)據(jù)卡項目為背景，針對目前無線數(shù)據(jù)卡自啟動子系統(tǒng)所存在的缺陷，進(jìn)行項目需求分析。對項目涉及到的高通AT命令、WDF過濾驅(qū)動、HS-USB協(xié)議、SCSI和BULK-ONLY協(xié)議等理論知識進(jìn)行介紹。在此基礎(chǔ)上，本文設(shè)計了新型自啟動子系統(tǒng)體系結(jié)構(gòu)。然后對子系統(tǒng)結(jié)構(gòu)進(jìn)行模塊劃分并對模塊進(jìn)行詳細(xì)設(shè)計與實現(xiàn)，最終實現(xiàn)了改進(jìn)后的自啟動子系統(tǒng)。該子系統(tǒng)在軟硬件結(jié)構(gòu)上都優(yōu)于原來的子系統(tǒng)，，解決了目前項目存在的缺陷。 本文最后將設(shè)計的自啟動子系統(tǒng)用于無線數(shù)據(jù)卡進(jìn)行測試，證明實現(xiàn)了無線數(shù)據(jù)卡設(shè)備的自啟動功能，改善了用戶體驗并滿足了設(shè)備生產(chǎn)商的需求。該項目現(xiàn)已經(jīng)研發(fā)成功，并且投入歐美市場。
[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.
