Abstract

A wireless device receives, from an SMF, a message for a PDU session establishment, wherein the message comprises a configuration information for determining whether one or more packets are associated with a plurality of packets of a data unit (DU) based on a timestamp field of the one or more packets. The wireless device determines, based on the configuration information, that a first packet, comprising a first timestamp field, is one of a first plurality of packets of a first DU, and a second packet, comprising a second timestamp field, is one of the first plurality of packets of the first DU. The wireless device sends, to a base station, the first packet and the second packet.

Claims (35)

1. A method comprising:

receiving, by a wireless device from a session management function (SMF), a message for a protocol data unit (PDU) session establishment, wherein the message comprises a configuration information for determining one or more packets that are of a plurality of packets of a data unit (DU), wherein the configuration information comprises a field indicating that the determining is based on a timestamp field of the one or more packets;

determining, by the wireless device and based on the configuration information, that:

a first packet, comprising a first timestamp field, is one of a first plurality of packets of a first DU; and

a second packet, comprising a second timestamp field, is one of the first plurality of packets of the first DU; and

sending, by the wireless device to a base station, the first packet and the second packet.

2. The method of claim 1 , wherein the configuration information indicates one or more protocols used for determining the plurality of packets.

3. The method of claim 1 , wherein the wireless device sends, to the base station, a packet data convergence protocol (PDCP) PDU comprising the first packet and a first number identifying the first plurality of packets.

4. The method of claim 3 , wherein the wireless device determines the first number based on the configuration information.

5. The method of claim 1 , wherein the first packet comprises a real-time transport protocol (RTP) packet.

6. The method of claim 1 , wherein the first packet comprises at least a portion of the first DU.

7. The method of claim 1 , further comprising determining by the wireless device and based on the configuration information, that a third packet, comprising a third timestamp field, is one of a second plurality of packets, of a second DU.

8. A wireless device comprising one or more processors and memory storing instructions that, when executed by the wireless device, cause the wireless device to:

receive, from a session management function (SMF), a message for a protocol data unit (PDU) session establishment, wherein the message comprises a configuration information for determining one or more packets that are of a plurality of packets of a data unit (DU), wherein the configuration information comprises a field indicating that the determining is based on a timestamp field of the one or more packets;

determine, based on the configuration information, that:

a first packet, comprising a first timestamp field, is one of a first plurality of packets of a first DU; and

a second packet, comprising a second timestamp field, is one of the first plurality of packets of the first DU; and

send, to a base station, the first packet and the second packet.

9. The wireless device of claim 8 , wherein the configuration information indicates one or more protocols used for determining the plurality of packets.

10. The wireless device of claim 8 , wherein the wireless device sends, to the base station, a packet data convergence protocol (PDCP) PDU comprising the first packet and a first number identifying the first plurality of packets.

11. The wireless device of claim 10 , wherein the wireless device determines the first number based on the configuration information.

12. The wireless device of claim 8 , wherein the first packet comprises a real-time transport protocol (RTP) packet.

13. The wireless device of claim 8 , wherein the first packet comprises at least a portion of the first DU.

14. The wireless device of claim 8 , further comprising determining by the wireless device and based on the configuration information, that a third packet, comprising a third timestamp field, is one of a second plurality of packets, of a second DU.

15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause a wireless device to:

receive, from a session management function (SMF), a message for a protocol data unit (PDU) session establishment, wherein the message comprises a configuration information for determining one or more packets that are of a plurality of packets of a data unit (DU), wherein the configuration information comprises a field indicating that the determining is based on a timestamp field of the one or more packets;

determine, based on the configuration information, that:

a first packet, comprising a first timestamp field, is one of a first plurality of packets of a first DU; and

a second packet, comprising a second timestamp field, is one of the first plurality of packets of the first DU; and

send, to a base station, the first packet and the second packet.

16. The non-transitory computer-readable medium of claim 15 , wherein the configuration information indicates one or more protocols used for determining the plurality of packets.

17. The non-transitory computer-readable medium of claim 15 , wherein the wireless device sends, to the base station, a packet data convergence protocol (PDCP) PDU comprising the first packet and a first number identifying the first plurality of packets.

18. The non-transitory computer-readable medium of claim 17 , wherein the wireless device determines the first number based on the configuration information.

19. The non-transitory computer-readable medium of claim 15 , wherein the first packet comprises a real-time transport protocol (RTP) packet.

20. The non-transitory computer-readable medium of claim 15 , wherein the first packet comprises at least a portion of the first DU.
