科技發展的趨勢，強烈的支持行動數位學習的擴展。然而，目前上市提供服務的全範圍行動網路，如GPRS(General Packet Radio Service)與UMTS(Universal Mobile Telecommunication System)，實際上只能提供大約50/300 kbps的資料傳輸速率，因此不能有效的支援內容豐富的多媒體傳輸服務。而在無線寬頻網路方面，WLAN(Wireless Local Area Network)能在小移動範圍的環境中提供將近30 Mbps的高速資料傳輸速率，但相對的它也面臨了涵蓋服務範圍上的問題。為了有效的支援行動與無所不在的多媒體數位學習，我們藉由整合GPRS/UMTS提供的精密行動管理(mobility management)機制與WLAN提供的寬頻傳輸服務，設計並發展雙網多媒體簡訊服務(GPRS/UMTS/WLAN multimedia messaging service, GWMMS)系統，此系統稱之為GWMMS系統。GWMMS系統提供了即時的簡訊通知、內容豐富的簡訊存取、及統合的簡訊服務，最特別的是提供了便宜的簡訊服務。以GWMM系統為基礎，我們提出了GWMMS行動數位學習系統雛形，進而使GWMMS系統展示GWMMS戶外教學系統。

Technological trends strongly favor the spread of mobile e-learning (M-learning). However, the existing full-coverage mobile networks, such as General Packet Radio Service (GPRS) and Universal Mobile Telecommunication System (UMTS), are not able to effectively support content-rich multimedia transmission since the practical data rates offered are limited to 50/300 kbps. In parallel with the full-coverage GPRS/UMTS networks, Wireless Local Area Network (WLAN) provides high-speed transmission services with actual data rates around 30 Mbps in a short-range local mobility environment. By integrating the sophisticated mobility management mechanism provided by GPRS/UMTS and the broadband transmission service provided by WLAN, we design and develop a GPRS/UMTS/WLAN multimedia messaging service (MMS) system, called GWMMS system. The GWMMS system provides instant messaging notification, content-rich messaging access, convergent, and especially, cheap messaging service. On the basis of the GWMMS system, we propose a GWMMS M-learning prototype. With the GWMMS M-learning prototype, we demonstrate a field-based learning system.
