MEC辅助的Inactive状态用户动态位置管理方案
Dynamic location management scheme based on MEC for Inactive UEs
摘要
Abstract
As an emerging technology of 5 G era, mobile edge computing (MEC) is able to support the system requirement of throughput, latency and intellectualization. Meanwhile, a new UE RRC state called UE RRC Inactive is introduced as a general state in 5 G systems. In this paper, based on the characteristics of Inactive state, we propose a packet data buffer and dynamic location management scheme based on MEC. The scheme caches data packets and updates the RNA (RAN notification area) of Inactive UEs by MEC which is located close to the g NB. Compared with the traditional schemes, it can effectively solve the capacity problem of the anchor g NB and realize the effective position management of UEs. In this paper, we make a comprehensive overview of Inactive state at first. Furthermore, we summarize the present paging and location tracking schemes and point out the problems. Then we introduce the characteristics, network architecture, device structure of MEC. Finally, we make a detailed description of the proposed dynamic location management scheme based on MEC for Inactive UEs.关键词
