Abstract
The IMS (IP Multimedia Subsystem) 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 SIP-based multimedia service session handoff method named MS <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> HM. To reduce the handoff delay between heterogeneous wireless networks, the MS <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> HM uses the methods of advance registration and old-new address temporary matching. We modeled the node processing delay and network transmission delay, and analyze the total delay and the packet loss rate of the MS <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> HM. The MS <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> HM 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.
