| Summary: | 碩士 === 國立中正大學 === 資訊工程研究所 === 99 === In order to provide a seamless handover in the Next-Generation Network (NGN), this paper proposes a cross-layer handover by combining the different layer protocols to provide the efficient handover of Session Initiation Protocol (SIP). We combine the Media Independent Handover (MIH), Redirect Tunneling in Media-independent Pre-Authentication (MPA-RT) and the SIP to provide the efficient handover. The terminal equipped (mobile node) can utilize the information provided by MIH to determine the best handover timing and target network. MPA-RT is used to reduce the handover time, packet loss and transmission delay. It is our previous work to prevent the packet loss in MPA. We use SIP to send the Binding update packet (BUP) to complete the handover procedure. Simulation results shows that the cross-layer handover can significantly reduce handover delay, jitter and the temporary packet buffer size, as compared with current alternatives.
