GSM Modem-Based Mobile Auxiliary Learning System

With the development of mobile communication technologies and the popularity of relating devices, mobile learning (M-learning) system has been used more and more widely. But most of existing M-learning systems have built on mobile platforms whose interfaces don't open to general education institutions. This limits M-learning application. In view of this, a novel mobile auxiliary learning system, called GSM modem-based mobile auxiliary learning system (GM-MAL) is proposed, which has advantages of low cost, user-friendly and convenience for secondary development. System design of GM-MAL including hardware structure, software function and working procedures has discussed in detail. From the analysis of At commands, PDU encoding and decoding, serial programming, the technical method how to realize GM-MAL are given. Practice has proved that GM-MAL can not only strengthen the contact of teaching and learning, but also promote students' learning and improve the teaching effect.
