基於TCP/IP之異質行動網路交遞協定

隨著行動網路朝向全IP環境邁進的同時，整合各種種類的網路成為一項日益受到重視的研究議題。在各種異質網路的整合中，交遞是必須用到與處理的一個重要項目。我們所謂的一個行動裝置可以在各種異質網路間交遞的能力，是指這個行動裝置可以在各種異質網路間自由移動時，同時也能夠維持資料傳輸的服務品質在一定水準以上，包含資料傳輸的連續性、可靠性、資料流量穩定性、多工性。為了達到無縫交遞與連續性連線的目標，本論文提出了一個基於TCP/IP且符合端對端原則的網路協定，來處理行動裝置連線狀態改變的問題。藉由符合端對端的原則，則無須中介的代理處理牽涉其中，如此，既可達到較好的效率並同時達到在異質網路間無縫交遞的目的。

When we are moving to the next generation All-IP environment, the issue of integrating WWAN and WLAN appears. In heterogeneous network integration, handover will be used. What is called having the ability of handover between WWAN and WLAN means a mobile device can move freely between different type of network and still satisfy the QoS (quality of service) requirement of various applications. In order to achieve the goal of seamless handover and connection continuity, this paper proposes an adaptive network protocol to handle the changes in the connection status of mobile devices in an End-to-End manner. By complying with End-to-End principle, no intermediate agents or gateways are involved, but still achieve the purpose of seamless handover between WLAN and WWAN.
