A method performed by a source long term evolution (LTE) base station includes buffering downlink user data packets for transmission to a mobile communication device in a buffer, sending the downlink user data packets to the mobile communication device, receiving uplink user data packets from the mobile communication device, receiving a handover response indicating a handover of the mobile communication device to a target base station, and selectively forwarding the downlink user data packets from said buffer to the target base station depending upon an RLC status report or hybrid automatic repeat request (HARQ) feedback information. In response to the receiving the handover response, the source LTE base station stops the sending the downlink user data packets to the mobile communication device and transmits a handover command to the mobile communication device.
