技术领域
本公开涉及通信技术领域，尤其涉及一种辅小区组维护方法、终端设备及网络节点。
背景技术
第五代(5Generation，5G)移动通信系统中，终端设备例如用户设备(User Equipment，UE)可采用双重连接(Dual Connectivity，DC)架构，包括两个小区组，分别为主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG)，该MCG对应于网络侧的主节点(Master Node，MN)，该SCG对应于网络侧的辅节点(secondary node，SN)。具体地，该MCG包括主小区(Primary Cell，PCell)和辅小区(Secondary Cell，SCell)，该SCG包括主辅小区(Primary Secondary Cell，PSCell)和SCell，而该PCell和PSCell又可统称为特殊小区(Special Cell，SpCell)。
当前，UE条件切换的主要过程为：源节点向一个或多个目标节点发送切换请求信息；目标节点向源节点反馈切换确认信息；源节点向UE发送条件切换的配置信息；UE评估候选小区是否满足切换的条件，满足后选择一个目标小区进行切换；UE在选择的目标小区发起随机接入过程；UE向目标节点发送切换完成信息；源节点向其他目标节点发送取消条件切换命令；其他目标节点向源节点发送条件切换取消确认命令。
在DC架构下，通信系统常需要部署大量的小小区和小基站，此时若采用相关技术中的基于条件的SCG维护过程，即对SCG进行改变，则需进行大量的配置信令操作，从而造成信令损耗，并可能无法即时有效的改变SCG小区，导致发生SCG失败，导致SCG的数据传输中断。
