Abstract: An apparatus and method for reordering traffic flow templates (TFTs) in a mobile communication system. The apparatus and method include a primary GPRS tunneling protocol (GTP) tunnel for transmitting and receiving packet data to and from a mobile station and one or more secondary GTP tunnels having the same mobile station address as the primary GTP tunnel and each being divided into different TFTs. The TFTs each include different packet filter contents so that the secondary GTP tunnels are separated through TFT packet filtering. A controller is adapted to sequentially perform TFT packet filtering on input packet data for the TFTs, manage statistical data of packet data successfully TFT packet filtered according to the TFTs, and reorder an order of the TFTs by comparing the statistical data of the packet data successfully TFT packet filtered for the TFTs if a preset period expires.
