　　今日,在市面上有越來越多的無線產品，譬如膝上型輕便電腦或掌上型個人數位助理。當這些行動使用者從一個網域移動到另一個網域，他們依然還想要持續傳送資料。此時，換手機制必須馬上被啟動。行動式網際網路通訊協定的註冊程序和會議初始協定的重新邀請機制能夠協助正在線上的通話重新建立連線。行動式網際網路通訊協定利用行動使用者的永久位址和轉交位址去完成註冊的程序；然而，會議初始協定必需藉由動態主機設定協定分配的新位址去完成重新邀請機制。由於行動式網際網路通訊協定和會議初始協定有數個問題存在，一些專家提出一套整合的架構以提高執行的效率。我們也提出一個新的方法去與行動式網際網路通訊協定和會議初始協定整合架構合併在一起並且在換手的期間利用這個多階層的行動方式來重新建立正在通話的連線。以多種架構進行模擬的結果，我們提出來的方法不但擁有比行動式網際網路通訊協定和會議初始協定較好的執行效率而且還超越兩協定的整合模式。它可以徹底地落實無間斷的行動通訊。

　Nowadays, there are more and more wireless products in the market conditions, like the laptop and PDA. When these mobile devices move from one domain to another, users expect that they can still send/receive data continuously. At this present moment, the handoff mechanism must be triggered right away. Mobile IP registration and SIP Re-INVITE method can help the online call to re-establish its session. Mobile IP uses the home address and the care-of address of the mobile user to accomplish the registration scheme; however, SIP depends on a new IP address from DHCP mechanism to complete the Re-INVITE procedure. Because there are several problems for these two approaches, some experts have proposed an integrated model using Mobile IP and SIP so as to enhance the performance. We also offer a new solution to combine the integrated architecture of Mobile IP and SIP, and employ this multi-layered mobility solutions to rebuild the calling session during handoff. Due to all performance evaluations for any model, our proposed approach not only owns better performance than Mobile IP and SIP but also surpasses the combined model of Mobile IP and SIP. So, it can be entirely practicable to the seamless mobility.
