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).
Claims28
A method for performing Traffic Flow Template (TFT) filtering according to Internet Protocol (IP) versions in a mobile communication system capable of supporting 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, the method comprising the steps of:
- extracting IP version-based information from a source IP address;
- and
- generating TFT information containing the extracted information and transmitting the generated TFT information to a Gateway GPRS (General Packet Radio Service) Support Node (GGSN).
A method for performing Traffic Flow Template (TFT) filtering according to Internet Protocol (IP) versions in a mobile communication system capable of supporting 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, the method comprising the steps of:
- when TFT information is received and the received TFT information corresponds to the second IP version address into which the first IP version address is inserted, extracting the first bits of the first IP version address from the second IP version address;
- generating new TFT information from the extracted first bits of the first IP version address;
- when an IP address of received packet data corresponds to the second IP version and the IP address is the second IP version address into which the first IP version address is inserted, extracting the first bits representing the first IP version address from the second IP version address;
- and
- performing the TFT packet filtering using the first bits extracted from the received packet data.
A method for performing Traffic Flow Template (TFT) filtering according to Internet Protocol versions in a mobile communication system capable of supporting 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, the method comprising the steps of:
- when a source IP address is the second IP address into which the first IP version address is inserted, allowing User Equipment (UE) to extract the first bits of the first IP version address from the second IP version address;
- allowing the UE to generate packet filter contents from the extracted first bits of the first IP version address, to generate TFT information containing the packet filter contents, and to transmit the generated TFT information to a Gateway GPRS (General Packet Radio Service) Support Node (GGSN);
- allowing the GGSN to store the TFT information received from the UE and to extract the first bits representing the first IP version address from the second IP version address when an IP address of received packet data corresponds to the second IP version and the IP address is the second IP version address into which the first IP version address is inserted;
- and
- allowing the GGSN to perform the TFT packet filtering using the first bits extracted from the received packet data.
