Data unit in wireless system
A user plane function UPF receives, from a SMF, a DU identification information for identifying a plurality of packets for one or more DUs of an application. The UPF receives a first plurality of packets, of the plurality of packets, of a first DU of the application; and a second plurality of packets, of the plurality of packets, of a second DU of the application. The UPF sends, to an access node and using the DU identification information a first GTP container comprising a first GTP header comprising a first number identifying the first plurality of packets, and a second GTP container comprising a second GTP header comprising a second number identifying the second plurality of packets.
1. A method comprising:
receiving, by a user plane function (UPF) from a session management function (SMF), a data unit (DU) identification information for identifying a plurality of packets for one or more DUs of an application;
receiving, by the UPF:
a first plurality of packets, of the plurality of packets, of a first DU of the application; and
a second plurality of packets, of the plurality of packets, of a second DU of the application; and
sending, by the UPF to an access node and using the DU identification information:
a first general packet radio service tunneling protocol (GTP) container comprising a first GTP header comprising a first number identifying the first plurality of packets; and
a second GTP container comprising a second GTP header comprising a second number identifying the second plurality of packets.
2. The method of claim 1 , wherein: the first GTP container further comprises a first packet of the first plurality of packets; and the second GTP container further comprises a second packet of the second plurality of packets.
3. The method of claim 2 , wherein the UPF determines the first number for the first packet and the second number of the second packet, based on the DU identification information.
4. The method of claim 1 , wherein the DU identification information indicates one or more header fields of one or more packets.
5. The method of claim 4 , wherein the one or more header fields comprises at least a real-time transport protocol (RTP) header.
6. The method of claim 1 , wherein the DU identification information indicates one or more protocols used for identifying the first number or the second number.
7. The method of claim 1 , wherein a packet forwarding control protocol (PFCP) message comprises the DU identification information.
8. A user plane function (UPF) comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the UPF to:
receive, from a session management function (SMF), a data unit (DU) identification information for identifying a plurality of packets for one or more DUs of an application;
receive:
a first plurality of packets, of the plurality of packets, of a first DU of the application; and
a second plurality of packets, of the plurality of packets, of a second DU of the application; and
send, to an access node and using the DU identification information:
a first general packet radio service tunneling protocol (GTP) container comprising a first GTP header comprising a first number identifying the first plurality of packets; and
a second GTP container comprising a second GTP header comprising a second number identifying the second plurality of packets.
9. The UPF of claim 8 , wherein: the first GTP container further comprises a first packet of the first plurality of packets; and the second GTP container further comprises a second packet of the second plurality of packets.
10. The UPF of claim 9 , wherein the UPF determines the first number for the first packet and the second number of the second packet, based on the DU identification information.
11. The UPF of claim 8 , wherein the DU identification information indicates one or more header fields of one or more packets.
12. The UPF of claim 11 , wherein the one or more header fields comprises at least a real-time transport protocol (RTP) header.
13. The UPF of claim 8 , wherein the DU identification information indicates one or more protocols used for identifying the first number or the second number.
14. The UPF of claim 8 , wherein a packet forwarding control protocol (PFCP) message comprises the DU identification information.
15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause a user plane function (UPF) to:
receive, from a session management function (SMF), a data unit (DU) identification information for identifying a plurality of packets for one or more DUs of an application;
receive:
a first plurality of packets, of the plurality of packets, of a first DU of the application; and
a second plurality of packets, of the plurality of packets, of a second DU of the application; and
send, to an access node and using the DU identification information:
a first general packet radio service tunneling protocol (GTP) container comprising a first GTP header comprising a first number identifying the first plurality of packets; and
a second GTP container comprising a second GTP header comprising a second number identifying the second plurality of packets.
16. The computer-readable medium of claim 15 , wherein: the first GTP container further comprises a first packet of the first plurality of packets; and the second GTP container further comprises a second packet of the second plurality of packets.
17. The computer-readable medium of claim 16 , wherein the UPF determines the first number for the first packet and the second number of the second packet, based on the DU identification information.
18. The computer-readable medium of claim 15 , wherein the DU identification information indicates one or more header fields of one or more packets.
19. The computer-readable medium of claim 18 , wherein the one or more header fields comprises at least a real-time transport protocol (RTP) header.
20. The computer-readable medium of claim 15 , wherein the DU identification information indicates one or more protocols used for identifying the first number or the second number.
