Abstract
A method performed by a central unit (CU) in a first radio access network (RAN) node comprises: establishing a dual connectivity (DC) of the first RAN node and a second RAN node for a wireless device; providing a service to the wireless device in the DC based on a distributed unit (DU) of the first and second RAN nodes; receiving, from a CU of the second RAN node in the DC, handover information for a handover of the wireless device from the second RAN node to the first RAN node; performing a packet data convergence protocol (PDCP) anchor change from the CU of the second RAN node to the CU of the first RAN node based on the handover information; and transmitting, to the DU of the first RAN node, a message comprising information instructing not to release the DU of the first RAN node after the PDCP anchor change.
