  • Patent number: 7324498
    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.

  • Publication number: 20060187835
    Abstract: An apparatus and method adjust an adaptive service bandwidth in a mobile communication system in which differentiated services for guaranteeing QoS are provided. Services are provided by using a bandwidth greater than an accepted reference value when resources of the network have a margin, and by using a weighted value according to a class when the network is in an overload state to efficiently transmit a packet and provide a user with optimal services.

  • Publication number: 20040205247
    Abstract: An apparatus and method for performing Traffic Flow Template (TFT) filtering according to Internet Protocol (IP) versions in a mobile communication system. The mobile communication system supports an address of a first IP version including first bits and an address of a second IP version including second bits containing the first bits. IP version-based information is extracted from the source IP address. TFT information containing the extracted information is generated and the generated TFT information is transmitted to a Gateway GPRS (General Packet Radio Service) Support Node (GGSN).
