摘要(中)

鑒於近年來，智慧型手持裝置的普遍率急速上升(包含手機、PDA和其他行動裝置)，行動裝置提供的功能也日漸強大，各種的應用軟體程式也逐漸移植到這些移動裝置上，進行各種日常生活的資訊處理應用。這些移動裝置隨時、隨地存取網路資源的概念，讓原本佈署於電腦系統上的應用服務，有了全新的操作體驗。但在目前的手持裝置架構當中，並沒有一套處理機制，能夠讓使用者將應用服務給隨插即用(Plug-and-play)，並能夠有效率的去引導、開發及管理這些多樣的功能服務，實現SOA架構。
在本研究中提出了在Android平台上以OSGi為基礎之服務遞送(Service Delivery)。藉由OSGi在不同的使用者操作情境下，透過遞送適合的 Bundle 元件，來讓數位資訊能夠更容易地進行交換傳遞，使得行動裝置擁有即時更新以及動態安裝/卸除服務的能力，達到更方便且更智慧的需求滿足。

摘要(英)

In recent years, the development of smart handheld devices is growing rapidly (including mobile phones, PDAs, and other mobile devices). The functionalities provided by mobile devices have become more and more powerful. A great many software applications are built on these mobile devices, and provide us real-time and useful daily life information. The new concept, namely “anytime and anywhere”, introduced by mobile devices, has changed our operation experiences of traditional computer applications. However, the current architecture does not have a handy mechanism that allows users to plug-and-play some software that they are interested in, and have the ability to guide the development and management of these various services.
In this research, we propose an OSGi-based Service Delivery mechanism on Android platform. Based on OSGi platform, end users can easily capture and spread the digital information by delivering suitable bundle components for different users’ scenarios.
