Session Initiation Protocol(SIP)被廣泛地被應用於網際網路電信領域中，同時也被採用為VoIP與3GPP的信號通訊協定，因此SIP的發展成為網際網路電信領域中備受矚目的研究議題。SIP的研究可分為四大方向，分別是terminal mobility、personal mobility、service mobility與session mobility。本論文將針對session mobility這個議題提出如何利用SIP讓使用者能在進行通話的過程中，自由的變換通話設備或將視訊串流隨意分流或取回的使用機制。我們將SIP所定義的User Agent(UA)擴充為Session Manager、Session User與Free Node三種不同的角色。依據這些角色所提供的能力，提出一套完整的機制，以解決收回整合的問題。最後我們採用具有開放原始碼的軟體電話來進行實做，並驗證這套機制的可行性。
