    摘要: A communication system and data transmission method thereof are provided. The method includes adding an end marker to the end of source data and transmitting the source data and the end marker for a Packet data network GateWay (PGW) to a source evolved Node B (eNB) if a handover is carried out from the source eNB to a target eNB while the PGW is transmitting the source data to the source eNB, forwarding the source data and the end marker from the source eNB to the target eNB, transmitting target data immediately following the source data from the PGW to the target eNB, and transmitting the source data and the target data, which is classified into the source data by the end marker and immediately follows the end of the source data, from the target eNB to user equipment.
