Abstract: Explicit signaling of End of Handover (EoH) advantageously indicates when user equipment (UE) has stopped using Packet Data Convergence Protocol (PDCP) handover mode. Radio Link Control (RLC) Acknowledge Mode (AM) delivers in order ensuring that all reordered packets have been received with no risk of delivering a gap packet when no longer in handover mode that would otherwise cause Hyper Frame Number (HFN) to be out of synchronization. Substantially at a time evolved Base Node (eNB) determines a gap will not be filled, eNB can convey an EoH indication to a served UE and can then deliver the PDCP Service Data Units (SDUs) with gaps to upper layers without delay.
