摘要

本文首先证明了移动IP协议是为可移动性而不是为会话连续性而设计的。相反,mSCTP(移动流控制传输协议)在会话连续性支持方面似乎是最好的协议,但它不支持位置管理机制,因此很难适应上下文感知的QoS以及其他基于位置知识的机制。另一方面,3GPP最初引入的标准化IP多媒体子系统(IMS)解决方案采用基于策略的QoS模型,将用户的订阅映射到预定义的QoS级别,应用基于服务的收费,防止盗窃服务。在本文中,我们提出了一种将mSCTP集成到IMS网络中的新方法,以促进会话连续性并提供服务控制机制。它是由一个基于mSCTP(移动流控制传输协议)的代理实现的,该代理作为具有多个物理接口(例如WLAN/UMTS)的移动节点的软垂直切换的锚点。基于msctp的代理还支持在异构无线环境中移动时为移动节点提供QoS配置和自适应。结果表明,该方法的切换信令成本比传统方法低23倍。

Multimedia session continuity with context-aware capability in IMS-based network
In this paper we firstly proved that Mobile IP protocols are designed for mobility but not for session continuity. In contradiction, mSCTP (mobile Stream Control Transmission Protocol) appears to be the best protocol with regard to session continuity support, however it does not support location management mechanisms, thus context-aware QoS as well as other mechanisms based on knowledge of location are hardly accommodated. On the other hand, the standardized IP Multimedia Subsystem (IMS) solution initially introduced by 3GPP adopts the policy-based QoS model to map user's subscription to a pre-defined QoS level, to apply service-based charging and to prevent Theft-of-Service. In this article we propose a new approach that integrates mSCTP into IMS networks to facilitate session continuity and to provide mechanisms for service control. It is realized by a proxy based on mSCTP (mobile Stream Control Transmission Protocol) that acts as an anchor point for soft vertical handover of mobile nodes, which have multiple physical interfaces (e.g., WLAN/UMTS). The mSCTP-based proxy also supports QoS provisioning and adaptation for the mobile nodes when moving in a heterogeneous wireless environment. Results show that the signaling cost for handover in our approach can be up to 23 times smaller than that in the conventional approach.
