Abstract :
There will be a great of Heterogeneous networks in Next Generation Network. Mobile Satellite system (MSS), great supplement of terrestrial network, provide large scale network coverage and is able to support IP multimedia services. We propose a SIP-based soft handoff scheme for integrated architecture of MSS and UMTS, as well as add satellite access gateway (SAG) in satellite station and terrestrial access gateway (TAG) in GPRS network as SIP proxy of Mobile Host (MH) to realize SIP soft handoff. This scheme could reduce the delay obviously and make the packet loss rate to zero.
