Abstract:	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.
