摘要
在R15中,5G的移动性采用传统的切换机制,切换性能难以满足时延敏感业务的要求,且因5G频率较高,其切换失败率也会较高,针对这些问题,在R16中对5G移动性技术进行了增强。首先介绍R16三种移动性增强技术的基本原理和信令流程,然后对三种增强技术的性能进行详细分析,最后根据每种增强技术的特性提出应用建议,为未来5G增强技术应用提供技术参考。
In R15,the handover performance of the traditional handover mechanism adopted for G mobility is difficult to meet the requirements of time delay sensitive service,and the high frequency of 5G leads to the high rate of handover failure.To solve these problems,5G mobility technology is enhanced in R16.This paper first introduces the basic principle and signaling process of three mobility enhancement technologies of R16,and then analyzes the performance of three mobility enhancement technologies in detail.Finally,some application suggestions of each mobility enhancement technology are provided according to its characteristics,which provides a reference for 5G enhancement technology application in the future.
