摘要(中)

在新一代的無線網路將預期提供一個無遠弗屆的傳輸架構，在這種架構下使用者將能享受穩定、高品質及多樣化的服務。然而在這樣的環境中使用者可以依時地的不同，再任何時間任合地點選擇最合適的傳輸方式。而為了要使這樣的無遠弗屆的傳輸環境能在以IP網路中被建構與實現，必須有一套具有提供無縫式的漫遊與快速的行動管理機制。然而為了提供高品質及多樣化的服務在資源的規劃上必須做妥善的動態管理。
因此在本論文中我們將分別針對行動管理、漫遊服務及資源規劃等問題提出相關的方法，關於無縫式的漫遊本本架構中藉由”Intelligent Location Server”來達成跨系統與網域的漫遊服務，而在資源規劃方面我們提出了一套”適用於多服務型態的動態的資源分配機制(ARASFM)” 來滿足各種不同服務類型的服務品質保證，對於及時性的連線，我藉由此方法將能減少斷線機率並增加系統的使用率。而關於非及時性的封包，此方法將能有效的降低封包遺失率與傳輸的平均延遲。而關於在IP網路中提供行動管理方面，本論文提出一套”System Independent Vertical Handover Scheme”。當使用者在完全獨立的系統下移動，藉由此方法將可以提供連續不中斷的連線品質。

摘要(英)

New generation wireless network is expected to provide seamless, high quality, and multi-media supported services via ubiquitous communication systems that allow users to determine the most suitable wireless access technology anytime, anywhere. In order to build a continuous and ubiquitous communication system over IP based network, the well-defined seamless roaming scheme and IP mobility support scheme must be offered for personal location management. The dynamic and smart resource allocation scheme is required to provide seamless, high quality and multi-media support services.
Therefore, this thesis proposes a novel scheme to realize the seamless roaming via an intelligent location server. For resource allocation, we propose an “Adaptive Resource Allocation Scheme for Multi-traffic Wireless Network” (ARASFM) to guarantee QoS, according to traffic type, user priority and user mobility. The proposed scheme is based on resource re-negotiation to lower the handover-dropping probability and increase the overall system utilization. In IP mobility support, we propose a “System Independent Vertical Handover Scheme” for IP based network that is maintaining continuous end-to-end connection while mobile node is performing handover via different wireless access technologies, which could belong to different operators.
