最近幾年，以SOA(service-oriented architecture) 服務導向架構的ATIS(Advanced Traveler Information Services) 先進旅行者資訊服務已經被發展出來。J2ME在行動裝置上已經被廣泛的應用到服務遞送(Service Delivery)平台。 隨著J2ME行動電話的日漸普及，使用J2ME的標準，可以使開發的程式在不同的J2ME行動電話上使用。再者行動電話執行程式效能不佳，最佳化程式，使得程式更有效率，成為一項重要的課題。因此本研究論文的目地是在J2ME平台上開發遞送ATIS服務，並且透過地圖傳輸的效能最佳化，道路及路名呈現的效能最佳化，使得地理圖層資料能夠更快速地傳送呈現結果到旅行者端。 Recently, ATIS services have been developed and delivered based on service-oriented architecture.J2ME has been widely used as a service delivery platform for mobile devices. Due to the J2ME mobile-phone is getting more popular, we can develop programs used on different J2ME mobile-phones based on J2ME.The computation power of mobile-phones is limited, so optimization becomes very important. The proposal of this thesis is to develop and deliver ATIS services on J2ME platform ,based on several performance optimization techniques such as map invocation ,map presentation.
