Abstract  Abstract

Technology for reducing packet transmissions is disclosed. A master evolved node B (MeNB) configured for dual connectivity can receive one or more acknowledgements (ACKs) from a user equipment (UE) indicating packets that were successfully received at the UE from a secondary evolved node B (SeNB). The MeNB can receive from the SeNB packet delivery information for the SeNB. The MeNB can receive an indication from the SeNB of an air-interface connection loss between the SeNB and the UE. The MeNB can identify remaining packets that were not sent from the SeNB to the UE based in part on the ACKs received from the UE and the packet delivery information received from the SeNB wherein the remaining packets are not sent to the UE due to the connection loss between the SeNB and the UE. The MeNB can send the remaining packets from the MeNB to the UE.
