Name	Type	Description
HandoverPacketHolderEnb	simple module	Manages packet buffering and forwarding during handover procedures at the base station. When a user equipment begins handover, tunnels downlink packets to the target base station via the backhaul interface. At the target base station, buffers incoming packets from both the backhaul tunnel and the network layer. Upon handover completion, releases buffered packets to the protocol stack in the correct order.
