FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a mobile station and a communication system. The mobile station comprises: a receiving means for receiving a first packet data convergence protocol (PDCP) protocol data unit (PDU), to which a first sequence number is added, from a source base station; a receiving means for receiving a second PDCP PDU from a target base station which uses a second sequence number transferred from the source base station as a sequence number of a PDCP service data unit (SDU), and creates a second PDCP PDU; a storage means for storing PDCP SDU corresponding to the first PDCP PDU and the PDCP SDU corresponding to the second PDCP PDU; and a means for performing ordered delivery of the stored PDCP SDU based on the sequence numbers corresponding to said PDCP SDU.
