<p>Provided are a wireless base station and mobile station with which it is possible to avoid an increase in C-Plane load, and reduce handover delay, even if there is a change in the type of PDCP-SN used in the cell after handover. The wireless base station (eNB#1) according to the present invention is equipped with a transmission unit (11) which is constituted in such a manner that if the mobile station UE performs a handover from cell #1 to cell #11 (or if performing a handover from cell #11 to cell #1), the mobile station UE is notified that the length of the PDCP-SN used in communications within the cell #11 (or cell #1) will change.</p> |
