摘要(中)

本論文基於WiMAX end-to-end network systems architecture Stage 2與Stage 3 ，整合應用層之SIP Terminal Mobility ，並藉由整合Stage 2與 Stage 3 所定義的ASN Anchored Mobility 來達成無縫換手的目標；另外，本論文透過ASN Anchored Mobility 與 SIP Mobility 的交互運用，企圖讓後端網路達到負載平衡。
論文內容簡單解說SIP Terminal Mobility 和 Mobile IPv4 與Mobile IPv6 ，以及IEEE 802.16e 換手階段的網路運作和 Stage 2、Stage 3 中進入網路與行動管理的部份，並說明如何整合ASN Anchored Mobility 與SIP Terminal Mobility。
最後，透過軟體模擬，比較本論文所提出的換手方式，分析各種換手方式的換手失敗率以及核心網路負載平衡狀況。

摘要(英)

This paper is a research of Application layer mobility management scheme , which base on WiMAX end-to-end network systems architecture Stage 2 and Stage 3. By combining the ASN Anchored Mobility and SIP Terminal Mobility, this scheme can shorten the handoff delay time caused by traditional SIP Terminal Mobility.
In the following part of this paper, we simply describe how 802.16e HO works, and we explain the procedure of Mobile IPv4、Mobile IPv6、SIP Terminal Mobility and WiMAX end-to-end network systems architecture Stage 2 and Stage 3. By analyzing the procedure of signal flow, we can combine SIP Terminal Mobility with WiMAX ASN Anchored Mobility. Also, we study how to use B2BUA to reduce HO delay and increase HO stability. In another part of our study , we try to use ASN Anchored Mobility and SIP Terminal Mobility to balance core network load.
Finally, in the software simulation, we compare the original WiMAX mobility management scheme and the proposed application layer mobility management scheme. The results of the simulation show that this application layer mobility management scheme can efficiency balance the core network load.
