HandoverPacketHolderEnb¶

//
// 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.
