Abstract
This application provides a communication method. In the method, a first node receives a first radio resource control (RRC) reconfiguration message from a first donor node through a second node. After the first node receives the first RRC reconfiguration message from the second node, the first node receives first indication information from the second node. When the first node determines, based on the first indication information, that the first RRC reconfiguration message becomes effective, the first node establishes an RRC connection to a second donor node based on the first RRC reconfiguration message. In the method, the first node and the second node are nodes in a group that performs group handover, the group handover is a cross-donor node group handover, the second node is a head node or the second node is connected to a head node, and the second node is a parent node of the first node.
