Updating multiple packet filters in a single bearer context IE
A method is disclosed, comprising: in a general packet radio services (GPRS) tunneling protocol (GTP) message to update a GTP tunnel with a traffic flow template (TFT), sending a first opcode in a header of a TFT message; sending a second opcode in a packet filter field of the TFT message; interpreting the first opcode to initiate at least two of creation, deletion, and updating of traffic flow templates (TFTs); and interpreting the second opcode to identify an existing packet filter for adding, replacing, and deleting a packet filter.
1. A method, comprising:
in a general packet radio services (GPRS) tunneling protocol (GTP) message to update a GTP tunnel with a traffic flow template (TFT), sending a first opcode in a header of a TFT message, the first opcode comprising a TFT operation code at TFT IE level;
sending a second opcode in a packet filter field of the TFT message, the second opcode comprising a Packet Filter Operation Code at Packet Filter level;
interpreting the first opcode to initiate at least two of creation, deletion, and updating of traffic flow templates (TFTs);
interpreting the second opcode to identify an existing packet filter for adding, replacing, or deleting a packet filter; and
consolidating two GTP messages into a single GTP message including the first opcode and the second opcode.
2. The method of claim 1 , wherein the first opcode is an update existing TFT opcode.
3. The method of claim 1 , wherein the first opcode is an update existing TFT opcode and wherein the first opcode has bit values (1, 0, 0) from bit 8 to bit 6 of a third octet of the TFT message.
4. The method of claim 1 , wherein the second opcode is a four-bit packet filter identifier.
5. The method of claim 1 , wherein the second opcode is associated with an operation corresponding to the first opcode and with a packet filter associated with the packet filter field of the second opcode.
6. The method of claim 1 , wherein the GTP tunnel is a downlink tunnel and wherein the TFT is applied to the downlink tunnel and wherein the first and second opcodes are interpreted within an operator network.
7. The method of claim 1 , wherein the GTP tunnel is an uplink tunnel and wherein the first and second opcode are interpreted at a user equipment (UE).
8. A non-transitory computer-readable medium containing instructions which, when executed at a processor located at a network node, causes the network node to perform steps comprising:
in a general packet radio services (GPRS) tunneling protocol (GTP) message to update a GTP tunnel with a traffic flow template (TFT), sending a first opcode in a header of a TFT message, the first opcode comprising a TFT operation code at TFT IE level;
sending a second opcode in a packet filter field of the TFT message, the second opcode comprising a Packet Filter Operation Code at Packet Filter level;
interpreting the first opcode to initiate at least two of creation, deletion, and updating of traffic flow templates (TFTs);
interpreting the second opcode to identify an existing packet filter for adding, replacing, or deleting a packet filter; and
consolidating two GTP messages into a single GTP message including the first opcode and the second opcode.
9. The non-transitory computer-readable medium of claim 8 , wherein the first opcode is an update existing TFT opcode.
10. The non-transitory computer-readable medium of claim 8 , wherein the first opcode is an update existing TFT opcode and wherein the first opcode has bit values (1, 0, 0) from bit 8 to bit 6 of a third octet of the TFT message.
11. The non-transitory computer-readable medium of claim 8 , wherein the second opcode is a four-bit packet filter identifier.
12. The non-transitory computer-readable medium of claim 8 , wherein the second opcode is associated with an operation corresponding to the first opcode and with a packet filter associated with the packet filter field of the second opcode.
13. The non-transitory computer-readable medium of claim 8 , wherein the GTP tunnel is a downlink tunnel and wherein the ITT is applied to the downlink tunnel and wherein the first and second opcodes are interpreted within an operator network.
14. The non-transitory computer-readable medium of claim 8 , wherein the GTP tunnel is an uplink tunnel and wherein the first and second opcode are interpreted at a user equipment (UE).
