面向5G的移动性管理关键技术探讨

Discussion on Key Techniques of Mobility Management Oriented to 5G

为了应对5G业务多样性给移动性管理带来的挑战,首先对移动性管理的技术现状进行了分析,总结了现有移动性管理方案面临的问题,然后基于软件定义网络的思想,结合3GPP正在制定的5G标准文稿中对移动性管理的需求,提出了面向5G的按需移动性管理的划分级别,并探讨了IETF提出的分布式移动性管理技术面临的挑战及发展趋势,为5G按需移动性管理技术的标准制定提供参考。

In order to cope with the challenges of mobility management caused by the diversity of 5G services, the status of mobility management technique was analyzed and the problems in existing mobility management schemes were summarized firstly. Then, according to the idea of software defined network （SDN） and requirements of mobility management in the 5G standard drafts drawn by 3GPP, the division level of on-demand mobility management oriented to 5G was proposed. Finally, the challenge and developmental trend of distributed mobility management technique proposed by IETF were discussed to provide the reference to the standard establishment of 5G on-demand mobility management.
