Abstract: A mechanism for enhancing service continuity for a serving node is described. The mechanism comprising, for each user equipment being served by the serving node, sending a report comprising measurements of neighbouring cells of the user equipment to the serving node. Upon receiving each report, said serving node is configured to determine at least one target cell for the user equipment, wherein said target cell is indicated by two different target cell identities. Said serving node is further configured to receive a notification from a control unit, notifying the serving node to be switched off; send a request to a control node linked to the serving node, wherein said request comprising, for each user equipment being served by the serving node, at least one target cell identity associated with the user equipment, an identity of the user equipment and its UE contexts; and send a message to each user equipment being served by the serving node, wherein said message comprising at least one another target cell identity associated with respective user equipment.
