摘要:

分析了当前移动性面临的难题以及可行的解决思路,同时研究了 3GPP 网络侧现有的业务连续性能力和关键特性,包括会话和服务连续模式、超高可靠与低时延通信、流量引导等。提出了一种基于网络侧和应用侧协同机制,满足低时延业务在边缘快速移动涉及跨MEC切换场景下的业务连续性要求。并探讨了移动性管理后续研究的总体思路和分阶段实施路径。

关键词: 会话和服务连续模式, 多接入边缘计算, 无状态设计, uRLLC

Abstract:

The current mobility problems and feasible solutions were analyzed,and the existing service continuity capabilities and key features on the network-side which were defined by 3GPP were studied,including SSC mode,uRLLC,traffic routing and so on.A network-side and application-side collaboration mechanism was proposed to satisfy the low latency services involving cross-MEC handover for fast mobility at the edge scenarios.The general idea of the follow-up study on mobility management and the path of phased implementation were also proposed.

Key words: SSC mode, multi-access edge computing, stateless design, uRLLC
