B3G異質網路整合分散型閘道器：HISN之實作

隨著無線網路與移動裝置的快速發展，人們越來越需要在任何時間、任何地點透過各式各樣的移動裝置來存取網際網路上的資訊與服務。因此，整合不同的異質網路並提供無縫式與連續性的服務成為在B3G（Beyond 3G）網路中的一個主要議題。而在異質網路整合中有幾項重要的考量。第一，由於異質網路擁有不同的網路通訊協定，並且不同移動裝置擁有不同的特性與能力，因此通訊協定與訊息的格式必須經過適當轉換才能被移動裝置所解讀與呈現。第二，議程移動性，當使用者在不同的網路中漫遊的時候，整合環境需要維持服務的連續性，確保使用者的服務不中斷。第三，個人化移動性，當使用者在不同的網路時，應該有共同的個人化的環境。第四，新的異質網路整合的架構不應該修改到既有的網路。最後，由於無線網路暴露在公共的區域時容易遭受攻擊，因此安全議題必須有所考量。在這篇論文中，我們設計並實作了一異質網路整合支援節點（HISN）用以整合異質網路，此外我們並提出了分散式的HISN網路架構。HISN則藉由議程管理機制替使用者維護了議程移動性、個人化移動性與終端裝置移動性。

With the rapid development for the technologies of mobile networks and mobile device, people are likely to access the information in Internet anytime and anywhere through different types of mobile devices. Integration of different kinds of networks to provide people a seamless and continuous network access service become a major issue in B3G network. There are several important issues for the integration of heterogeneous networks. First, due to the different network protocols and device capabilities, protocol and message format conversion need be done. Second, the “Session Mobility”, the maintenance for the service session continuity while users roam among different networks, should be considered. Third “Personal Mobility”, a personal environment, to users while residing in different kinds of network should be achieved. Fourth, the existing network protocols should not be notified for the new infrastructure introduced to integrate the heterogeneous networks. Finally, due to the exposure of communication media and information exchanges, security issue should be considered. In this thesis, we design and implement a Heterogeneous network Integration Support Node (HISN) for the integration of heterogeneous wireless networks integration. Then, we propose a distributed HISN network architecture. The HISN maintains the Session Mobility, Personal Mobility, and Terminal Mobility of mobile users through the Session Management mechanism.
