A dual connection re-establishment method, a non-transitory computer-readable storage medium, and a node are disclosed. The dual connection re-establishment method may include: sending a configuration information request to a target secondary node (SN) in response to a RRC connection re-establishment completion instruction sent by a UE (S1); receiving first configuration information fed back by the target SN (S2); and sending the first configuration information, and second configuration information corresponding to the MN to the UE for the UE to complete the RRC connection reconfiguration with the MN and the target SN according to the first configuration information and the second configuration information (S3).
