Abstract
Official abstract text for this publication.
Provided is a radio base station and a mobile station capable of reducing a handover delay while avoiding an increase of a load on the C-Plane even in a case where the kind of the PDCP-SN used within a cell after the handover is changed. A radio base station eNB according to the present invention includes a transmission unit configured to notify a mobile station UE that the length of the PDCP-SN used in communication within the first cell (or the second cell) is changed in a case where the mobile station UE performs a handover from the second cell to the first cell (or in a case where the mobile station UE performs a handover from the first cell to the second cell).
First claim
Opening claim text (preview).
The invention claimed is: 1. A radio base station that manages a first cell or a second cell in a mobile communication system, wherein: in the mobile communication system, the first cell using a first sequence number as a sequence number in a PDCP (Packet Data Convergence Protocol) layer and the second cell using a second sequence number that has a length longer than the length of the first sequence number as a sequence number in the PDCP layer are provided, the radio base stati…
