| 摘 要： | 因多协议标记交换(MPLS)技术将扩展用于未来移动网络的无线接入子网,于是提出将MPLS和移动IP微移动技术结合。在分析已有微移动方案的基础上,提出一种基于MPLS的微移动管理新架构。通过在域内增设一个存储漫游主机信息的本地移动管理服务器(LMMS)和若干寻呼服务器(PS),提供寻呼功能,消除网络瓶颈,并支持服务质量(QoS)保证。最后详细描述了注册、切换等信令流程,总结了新方案的技术优势。

| Abstract: | MPLS technology will be extended to be used in wireless access subnet of the future mobile networks.The idea is emerged of applying the technology of IP micro-mobility to MPLS-based wireless access subnet.Following an analysis of existing micro-mobility management approaches,a new MPLSbased architecture for micro-mobility management is proposed,where a Local Mobility Management Server(LMMS) storing the information of roaming hosts and some Paging Servers(PSs) are included.In addition to the paging functionality,the problem of network bottleneck is eliminated and QoS support is provided.The signaling procedure of registration and handoff is detailed and the technical superiority of the proposed scheme is summarized. |
