隨著個人行動通訊設備的普及，無細縫的無線通訊網路將使人跟人之間的聯繫變得簡單。藉由無線軟體下載的功能，無線通訊設備與通訊協定的可重新設定化，不僅讓個人行動通訊可以在全球的無線通訊網中可隨意取得服務，也為行動通訊系統提供許多加值服務，如下載特定語言的使用介面等。在現有的通訊技術支援下，為了因應此一趨勢發展，本篇論文提出了一個整合的系統架構軟體下載系統，透過可重新軟體設定的行動終端機及軟體下載伺服器的整合，行動終端機得以利用HTTP傳輸協定下載一般通訊軟體模組，如使用者介面模組等。
此軟體下載系統主要分成可重新軟體設定行動終端機及下載伺服器兩部分，可重新軟體設定終端機主要以Java虛擬根機器逹成軟體模組的加入和移除，無線下載機制目前則使用SMS作為資料載具，並且客戶端及伺服器端均藉由HTTP傳輸協定的使用以逹成下載要求和取得回應；而下載伺服器建構在遠端的網際網路上，利用無線閘道器及一般網路伺服的整合提供客戶端連線要求。因此，在此軟體下載系統架構下，行動終端機可以利用無線或有線通訊方式向軟體下載伺服器取得要求的軟體模組，新增或移除舊有軟體之後進而逹成軟體重新設定功能。
