摘要(中) 無線通訊在過去數十年急遽成長,各種創新技術相繼被制定、問世,已革命性地改變人們漫遊於 Internet的方式。在台灣,我們已有 WiFi、3.5G及 WiMAX 三種無線上網方式。而不管是哪種方式,其速率已可滿足大部份上網需求。然而,在這變化下也產生了問題。對營運商來說,要如何在各種網路上為用戶繼續提供好品質的服務?對使用者來說,該如何因應所在環境選擇最好的上網方式?針對前者,雖有 IP Multimedia Subsystem(IMS)的制定,但很明顯地,用戶仍需要知悉其協定的程式,以存取營運商提供的服務。
  近年來,社交網站的蓬勃成長,加速了人與人間的交流。用戶能於其上發現朋友、分享內容、建立各種社群、…等。據 2010年初的一項調查,行動上網的用戶超過一半為進行社交活動。另有一項研究指出,IMS與此領域的結合,可為用戶帶來更佳的服務體驗。
  本篇論文意圖實作出與 IMS 客戶端軟體整合之異質無線網路連線管理程式,能同時管理各種無線上網方式,帶來更好的上網體驗。另外,在目前實驗室已開發成熟之 IMS客戶端軟體上,加入影音分享之元素。
摘要(英) The wireless communications have been evolving quite rapidly for last few decades. Innovative technologies of various kinds were one by one standardized and deployed, which has revolutionized the way people surfs the Internet. In Taiwan, we nowadays have WiFi, 3.5G and WiMAX to choose from. Whatever the technology you use suffices most needs for accessing the information on the Internet. However, some issues arise from this change. From operator’’s point of view, it wonders how to deliver services over different networks while maintaining good Quality of Service(QoS); From user’’s point of view, he/she wonders how to select best network based on the context. The advent of IP Multimedia Subsystem(IMS) tries to address the former problem. With its introduction, it’s apparent that subscribers demand a client application to gain access to it.
The rise of social networking sites promotes the interpersonal relationships in recent years. People discover their friends, share contents, create communities, …, and so on via them. A survey conducted in early 2010 reveals that more than half of mobile Internet users go online to socialize. A research found that the combination of IMS and the world of social networking brings about far better service experiences.
The thesis presents a connection manager for heterogeneous wireless networks, which is further integrated with the mature IMS client developed by our laboratory. The aim is to provide better surfing experiences. In addition, video sharing element is added to the IMS client.
