Abstract

The IP Multimedia Subsystem (IMS) can provide multimedia services between heterogeneous wireless networks. But the efficiency of the service session handoff will bring a significant impact to user experience. For the integration of heterogeneous wireless networks, we propose a Session Initiation Protocol (SIP) based multimedia service session handoff method named MS²HM. To reduce the handoff delay between heterogeneous wireless networks, the MS²HM uses the methods of advance registration and old-new address temporary matching. We modelled the node processing delay and network transmission delay, and analyse the total delay and the packet loss rate of the MS²HM. Specially, this paper contrastively analyses the handoff delay under different frame error control in the 3G-WLAN integrated network, and the result shows that MS²HM has lower handoff delay than the method proposed by Wedlund and Schulzrinne. The MS²HM can meet the low delay and low packet loss rate requirements of IMS service session handoff between heterogeneous wireless networks, and ensure the QoS of the IMS services.
