摘要：
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.
摘要（中）：
切换结束（EoH）的显式信令有利地指示用户设备（UE）何时停止使用分组数据汇聚协议（PDCP）切换模式。 无线电链路控制（RLC）确认模式（AM）提供以确保所有重新排序的分组已被接收，而不会在不再处于切换模式时递送间隔分组的风险，否则将导致超帧数（HFN）超出 同步。 基本上在演进的基站（eNB）确定间隙将不被填充的情况下，eNB可以向被服务的UE传达EoH指示，然后可以将具有间隙的PDCP服务数据单元（SDU）传送到上层，而不会延迟。
