Mobile SCTP Stream Control Transmission Protocol IETF RFC 2960
A new IP transport protocol, existing at an equivalent level with UDP and TCP. IETF的SIGTRAN(Signaling Transport)工作團隊所制定。 銜接網際網路電信系統與傳統的SS7網路。

Mobile SCTP 修正在 IP上使用 TCP傳送電信訊號時所遇到的許多缺點而制定的通訊協定,目的就是為了能夠更有效率的在 IP上傳送電信系統所需要的控制訊號。 提供了可靠的傳輸服務,運作於完整的IP網路環境中,並可適用於IPv4與IPv6。 提供了流量控制、重送機制,以提供上層的M3UA一個穩定可靠的傳輸介面。

SIP Mobility Goal: Use SIP for supporting terminal, personal and service mobility in a mobile wireless Internet, i.e., devise a comprehensive SIP-centric mobility management scheme, propose necessary (if any) extensions or modifications to the SIP protocol.

SIP Mobility Several issues: SIP has already supported mobility
SIP mobility support with mobil IP Architecture Handoff Delay End-to-end delay,etc.

Mobile IP 組成原件 : Mobile Node (MN) Home Agent (HA) Foreign Agent (FA)
Correspondent Node (CN)
8
Mobile IP 運作過程 : Agent Discovery Registration Tunneling MN尋找HA與FA階段
HA建立與外地之MN間通道階段
