Mobility-aware P/I-CSCF: A solution for achieving seamless handover in IMS

Julien Arnaud, Daniel Negru
2012 2012 IEEE Symposium on Computers and Communications (ISCC)  
This paper is focusing on IMS session continuity of a Mobile Node (MN) roaming from different access technologies. Comparison between different mobility solutions used in NGNs are addressed. Vertical mobility using End-User context information and SIP signaling are foreseen to efficiently comply to 3GPP standards and to provide enhanced end-user satisfaction. The usage of SIP mobility within our solution does not introduce any change in the signaling functionalities nor the architecture. Only

This paper also introduces a new algorithm in the MN to handle incoming media from different network interfaces. A proof-ofconcept involving wlan to 3G mobility validates our analysis and provide interesting results.
