Abstract
The invention relates to a method for efficiently performing a SeNB change for a UE in dual connectivity. When reconfiguring a data radio bearer going via the SeNB to another target base station, the UE may compile a PDCP status report comprising status information for all of the data radio bearer going via the SeNB, accompanied respectively by a radio bearer ID to identify the radio bearer to which the status report information pertains. Further, the PDCP status report is directly transmitted by the UE to the MeNB to avoid the backhaul delay between the SeNB and the MeNB; this may be done by using a signaling radio bearer (e.g. RRC message), or data radio bearer to the MeNB (e.g. PDCP control PDU), or by using a physical channel transmission to the MeNB (e.g. MAC CE).
