摘要:

移动性管理是移动通信中一个非常重要的关键技术。在充分研究现有移动性管理技术和SDN创新架构的基础上,提出了一个基于SDN 的移动性管理机制探讨方案,给出了架构示意图,详细分析了切换过程中的信令流程。本方案无需建立隧道,能有效解决现有移动性管理方案中GTP头开销大、信令增多、不支持无缝切换及路由效率低下等问题,符合未来网络架构发展的趋势。

关键词: 移动性管理, 软件定义网络, 无隧道

Abstract:

Mobility management is a key technology in the mobile communication network.On the basis of analyzing the current mobility management technologies and researching SDN,an SDN-based mobility management mechanism without tunnel was presented,which was applicable to solve the existing issues such as GTP overheads,increasing signa1,non-seamless handover,and low routing efficient,and was in line with the future network trend as well.The architecture of this proposal was depicted,and the signal procedure was minutely dissected.

Key words: mobility management, software-defined networking, non-tunneling
