在行動運算環境中，基於效能與網路通訊品質考量，使用異質性網路介面或異質性裝置觀賞多媒體串流是無可避免的。當使用者切換異質性網路介面或異質性裝置時，多媒體串流之遷移主要確保使用者正在觀賞的多媒體串流可以繼續地播放。現行解決多媒體串流遷移的方法須修改多媒體串流伺服器、路由器、代理伺服器、多媒體應用程式或網路通訊協定。然而，現行的方法都有相容性問題。因此，本論文提出一個新穎的行動管理方法，此方法使用會議層接合技術實現多媒體串流之遷移，且僅需修改用戶端，故此方法解決相容性問題且可運作於現行網路基礎架構與多媒體應用程式。此外，本論文所提出之方法已實作於Linux作業系統，並經由實地測試之數據證明此方法僅需花費些許額外負擔(Overhead)。

In mobile computing, it is unavoidable to receive multimedia stream in a session through heterogeneous network interfaces or heterogeneous devices for better communication quality and performance. Session migration aims to maintain the continuity of the ongoing multimedia stream among the network interfaces and the devices. However, current approaches for session migration have compatibility problems because they modify streaming servers, routers, proxies, applications, or protocols. In the thesis, we propose a novel mobility management approach by means of session splice to achieve session migration. The approach maintains the continuity of the ongoing multimedia stream among the network interfaces and the devices without any modification excepting the end host. Without compatibility problems in other approaches, our approach can cooperate with existing Internet infrastructures and legacy applications. Our mobility management approach is realized in Linux and the experimental results show that the approach can achieve session migration with a slight overhead.
