Abstract
本申请提供了一种IAB节点双连接建立的方法和通信装置，该方法包括：第一IAB节点与该第一IAB节点的主宿主节点建立第一F1接口；第一IAB节点获取其连接到辅宿主节点下的互联网协议IP地址，和/或，其连接到该辅宿主节点下的服务小区的配置信息；第一IAB节点向该辅宿主节点发送用于建立与辅宿主节点之间的第二F1接口的请求，该请求中包括该第一IAB节点连接到该辅宿主节点下的服务小区的配置信息。本申请提供的方法，一个IAB节点同时与主宿主节点和辅宿主节点建立F1接口。降低了IAB节点切换至辅宿主节点后建立F1接口的时延，避免了IAB节点切换宿主节点时延导致业务中断的问题，保障了通信质量，提高通信效率。
