背景技术
随着网络的不断演进，新的网络架构设计将迎来新的发展周期，未来的网络架构将全面实现开放化和通用化的结构设计。
在如图1所示的相关技术的第五代移动通信(the 5th generation mobile communication,5G)网络架构中，用户设备(user equipment,UE)通过无线接口接入到下一代基站(Next Generation Node Base，gNB)，然后由gNB进行控制面无线资源控制(Radio Resource Control,RRC)信令连接的建立，以及用户面无线资源的分配等工作，伴随着UE的移动，UE的信令连接会在不同gNB间(小区)进行切换操作(即删除/重建)，同时，也会变换UE与网络的业务数据传输链路。按照传统的网络架构模型，移动性相关的控制处理等特性完全集中在单个物理实体上，存在集中化、不通用化的缺陷，限制了通信网络的开放化和通用化。相应地，这样的架构也无法适应未来的网络演进和发展。
