臺灣博碩士論文加值系統

本研究針對Internet上各式各樣的資訊與服務,進行有系統的歸納與分析,試圖提出一個功能完整的多用途閘道架構。目的是在改善大哥大系統業者為了一時之需而針對特定服務所設計之Gateway缺點。在大哥大手機取得Internet的資訊與服務的過程中,扮演中介者角色的Gateway,是機動式商務環境中舉足輕重的一員,若能對Gateway有一完整的功能考量,將可降低機動式商務環境的建構成本,並且使得大哥大所能提供的資訊與服務更為多樣化。
論文中,首先針對Internet上的資訊與服務,進行傳送方式.服務傳送頻率.安全需求程度及資料流向等本質上的分析,以瞭解各類服務的特性,接著,再針對服務的特性,分析出多用途閘道應有的對應機制,以得知一個功能完整的多用途閘道,應該具備哪些基本功能。另外,本論文以WAP的模擬環境實作出大哥大手機取得Internet上服務之範例,說明多用途閘道之可行性。最後,以圖解說明,一個功能完整的多用途閘道將來可能的用途及應用領域。

This research analysis feature of every service on Internet and try to provide potent Multi-Purpose Gateway . The goal of this research is to improve the disadvantage of gateway designed by wireless communication system developer . In the process of people use handset to get service from Internet . Gateway is on an important position between handset and Internet service server . So,if we can design a protent gateway . We will decrease the cost of building mobile commerce . And people will get more service from internet by handset .
In this thesis, first, analysis the feature of every service on internet . Second, find the function of Multi-Purpose Gateway based on feature of every service . Then write some really example to show how to use handset to get service from internet at WAP simulated environment . Finally, analysis purpose of the Multi-Purpose Gateway .
