Abstract
Official abstract text for this publication.
A mobile station that includes a receiving means for receiving first PDCP (Packet Data Convergence Protocol) PDU (Protocol Data Unit) to which a first sequence number is added from a source base station; a receiving means for receiving second PDCP PDU from a target base station that applies a second sequence number transferred from the source base station as a sequence number of PDCP (Packet Data Convergence Protocol) SDU (Service Data Unit) received from a host station and creates the second PDCP PDU and a storage means for storing PDCP SDU corresponding to the first PDCP PDU and PDCP SDU corresponding to the second PDCP PDU and means for performing in order delivery of the stored PDCP SDUs based on the sequence numbers corresponding to the PDCP SDUs.
First claim
Opening claim text (preview).
What is claimed is: 1. A mobile station comprising: a receiver configured to receive a first PDCP (Packet Data Convergence Protocol) PDU (Protocol Data Unit) to which a first sequence number is added from a source base station and a second PDCP PDU from a target base station that applies a second sequence number transferred from the source base station as a sequence number of a PDCP (Packet Data Convergence Protocol) SDU (Service Data Unit) received from a host station and creat…
