在現今生活中，行動終端使用者可以在有著多種不同無線網路技術之異質網路環境中移動與行動且使用有著多網路介面之裝置來存取各式網路服務。
而最重要的一件事情是在移動過程中可以達到無縫切換。
多路徑傳輸控制協定 (MPTCP) 是傳輸控制協定 (TCP) 的延伸版本，准許同時使用多種網路介面與多條路徑來傳遞原傳輸控制協定中單一連線之資料封包。
多路徑傳輸控制協定中完全多路徑傳輸操作模式 (Full-mode) 能夠支援移動性與換手切換，
然而多路徑傳輸控制協定在兩不匹配網路環境參數之傳輸路徑上有著吞吐量效益低落表現的問題。
為了增進效能表現，我們須透過決策方法來決定一時間點上切換多路徑傳輸控制協定操作模式。
本論文中，我們使用一換手切換方法來切換多路徑傳輸控制協定工作模式，增進多路徑傳輸控制協換手性能，並將方法實作在現實無線區域網到行動網路的環境中。

In today, the mobile users can use a device with multiple interfaces to access services and walk in the heterogeneous networks environment.
One important thing is seamless handover. Multipath TCP (MPTCP) is a major extension to TCP and can send data with two paths.
The full-mode of MPTCP working operations can support seamless handover. MPTCP has low performance efficiency with two asymmetric paths parameters.
For improve performance, we use a handover decision method to start up MPTCP.
We implement experiments in real-world WLAN to mobile scenario.
