摘要

IMS (IP多媒体子系统)能够在异构无线网络之间提供多媒体业务。但是服务会话切换的效率会给用户体验带来很大的影响。针对异构无线网络的集成问题，提出了一种基于sip协议的多媒体业务会话切换方法MS2HM。为了减少异构无线网络之间的切换延迟，MS2HM采用了提前注册和新旧地址临时匹配的方法。建立了节点处理时延和网络传输时延模型，分析了MS2HM的总时延和丢包率。MS2HM能够满足异构无线网络间IMS业务会话切换的低时延、低丢包率要求，保证IMS业务的QoS。

MS2HM: A Multimedia Service Session Handoff Method between Heterogeneous Wireless Networks

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 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 modeled the node processing delay and network transmission delay, and analyze the total delay and the packet loss rate of the MS2HM. 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.
