Abstract

In order to achieve seamless handover for real-time applications in the IP Multimedia Subsystem (IMS) of the next-generation network, a multi-protocol combined handover mechanism is proposed. In this work, we combine SIP (Session Initiation Protocol), FMIP (Fast Mobile IPv6 Protocol) and MIH (Media Independent Handover) protocols by cross-layer design and optimize these protocols´ signaling flows to improve vertical handover performance. Theoretical analysis and simulation result illustrate that our proposed mechanism is ¹better than the original SIP and MIH combination handover mechanism in service interrupt time and packets loss aspects.
