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