摘要

本篇論文提出ㄧ新的QoS 連線建立管理機制- RSVP 與802.16 運作整 合流程，可以在IEEE 802.16 與IEEE 802.11e 混合的異質網路架構下進行 運作，以及當行動節點從原本服務的SS 移動到新的SS 之後，如何將原本 SS 下所建立的QoS 路徑，轉移到新的SS 之下。並且提出一套動態頻寬管 理機制，使得在資源不足的情況下，讓即時性的服務在轉移時有較高的優 先權取得頻寬使用，降低轉移失敗的機率。 經由模擬結果得知，本論文所提出之動態頻寬管理機制，在適當的參 數設定下，的確可以使得即時性的服務在進行轉移時，降低轉移失敗的機 率。

This paper proposes a new mechanism of setting up QoS connection –
RSVP and 802.16 operating integrated procedure, it can work in the IEEE
802.16 and IEEE 802.11e hybrid network, and how to transfer QoS link from
the serving SS to target SS when the mobile node moved from serving SS to
the target SS. Furthermore, we propose a mechanism of dynamic bandwidth
management, it make the real-time services get high priority to acquire
bandwidth when the real-time services do the handoff procedure and reduce
handoff call blocking probability when the resource is insufficient.
Simulation results show the mechanism of dynamic bandwidth
management can meet the handoff call blocking probability is reduced when
the real-time services do the handoff procedure if the parameters are configured
appropriately.
