摘要

对无线和移动服务日益增长的需求已经将最近的研究重点放在下一代IPv6网络的移动支持和QoS配置上。为了为此类网络提供无缝通信，提出了快速移动IPv6 (FMIPv6)和分层移动IPv6 (HMIPv6)。此外，3GPP还引入了IP多媒体子系统(IMS)作为下一代基于IP的多媒体业务融合基础设施。为了改善移动IMS-IPv6切换延迟和QoS提供，本文提出了两种上下文传输方案:预测式和被动式，在切换过程中协商QoS参数和预留资源。提出的方案提高了服务质量。通过分析对所提机制的性能进行了评价。

Using context transfer mechanisms to Improve Mobile IMS-IPv6 Handover Latency and QoS provisioning

The growing demand for wireless and mobile services has set the recent research sights on mobility support and QoS provisioning for next generation IPv6 networks. To provide seamless communications for such networks, fast mobile IPv6 (FMIPv6) and hierarchical mobile IPv6 (HMIPv6) has been proposed. Moreover, 3GPP has introduced IP multimedia subsystem (IMS) as the next generation IP based infrastructure for multimedia services convergence. In this paper, to Improve mobile IMS-IPv6 handover latency and QoS provisioning we present two context transfer scheme, predictive and reactive, to negotiate QoS parameters and reserve resources along the handover. The proposed schemes improve the service quality. The performances of the proposed mechanisms are evaluated by analysis.
