近年來，Web Services無疑的已經成為應用於電子商務（e-commerce）的一項重大技術。同時，快速成長的行動通訊網路技術以及日漸普及的手持式行動裝置，也促成了行動電子商務（m-commerce）的快速發展。

　　然而，在無線網路的環境下進行Web Services的資料傳輸，仍然有許多困難必須克服。首先，與有線網路環境相比，無線網路環境提供的頻寬較為不足。而取用Web Services透過的SOAP訊息經常比需耗費大量的來回訊息傳輸才能完成一個運作，無線網路其較差的穩定性也可能無法支援這樣一個連續的傳輸動作。因此我們必須採用其他的策略來部署一個Mobile Web Services。

　　在本論文中我們提出了一個傳輸Mobile Web Services的方案。我們並不遵行現行Web Services的輕量客戶端模型（Thin Client Model），取而代之我們採用一個智慧型客戶端模型（Smart Client Model）來有效減少Web Services必須耗用的大量傳輸量。為了實現這個智慧型客戶端模型，我們的Mobile Web Services傳輸方案是建立在廣播模式基礎（broadcast-based）上的。部分的Web Services運算可以從伺服器端移至客戶端運行，藉以減少其傳輸需求。

　　由於我們的傳輸模型是建立在廣播基礎上的，我們提出一個廣播排程演算法稱為EDDB（Exponentially Duplicate Data Broadcasting ），以及一個資料索引技術稱為DCI（Detached Channel Indexing）來增強此傳輸模型的效能表現。

　　Web Services are undeniably one of the most significant e-commerce concepts of the world in recent years. At the same time, advances in mobile communications and the continuously increasing number of users of hand-held terminals force the rapid development of m-commerce.

　　Transmitting web services in a wireless network has some difficulties to overcome. First, a wireless network provides a much lower bandwidth than a fixed network. Second, because of SOAP messages need a frequent round-trip connection, a wireless network may not stable enough to support a web service sequence round-trip transporting. Thus we may need to adopt another strategy to transmit mobile web services.

　　In this paper, we propose a scheme to transmit mobile web services messages. We don’t follow the thin client model in existing web service architecture, instead we propose a flexible “smart client model” to decrease the frequent connection of existing web services architecture. To realize the “smart client model”, our transmission scheme is broadcast-based. Part of the mobile web services executions can be designed to be downloaded to a client’s mobile device, so that reduce the connection quantity.

　　Due to our transmission scheme is broadcast based, we propose a broadcast scheduling algorithm named EDDB (Exponentially Duplicate Data Broadcasting) and an indexing method named DCI (Detached Channel Indexing) to enhance our scheme’s performance.
