Technical Field

[0003] The present application belongs to the field of wireless communication technology, and specifically relates to a processing method, a processing device, a communication device, and a readable storage medium. Background Art

[0004] With the development of wireless communication technology, some operations in communication systems consider processing data at the granularity of packet sets (such as Protocol Data Unit (PDU) Sets). This requires obtaining the packet set information corresponding to the packet. Therefore, the packet needs to be marked with the packet set information corresponding to the packet (such as PDU Set information). However, in communication networks, packets are not always marked with the packet set information corresponding to the packet. The network equipment that requires the packet set information corresponding to the packet (such as the Radio Access Network (RAN)) and the network equipment that performs the packet marking (such as the PDU Session Anchor (PSA) User Plane Function (UPF)) on the packet are different communication devices, and there is no communication mechanism between the two. As a result, there are scenarios where the RAN requires the packet set information corresponding to the packet, but the PSA UPF does not mark the packet with the packet, so the RAN cannot process data at the granularity of packet sets (such as PDU Sets). Therefore, the existing technology still has problems in triggering the operation of marking the packet with "packet set information (such as PDU Set information)" on the packet.

The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR systems, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0197] In communication services, such as Extended Reality (XR) services, video frames or slices are often composed of multiple data packets. Processing data packet sets is called PDU Set processing. Marking a data packet with PDU Set information refers to identifying the PDU Set to which the data packet belongs.

[0198] Currently, the PSA UPF will mark the PDU Set information in the General Packet Radio Service (GPRS) Tunneling Protocol (GTP)-U header of the data packet only if specific conditions are met (such as the RAN supports PDU Set processing and at least one of the delay budget (PSDB), PDU set error rate (PSER), and PDU Set integrated handling information (PSIHI) is accepted by the RAN). The RAN can then obtain the corresponding PDU Set information from the GTP-U header of the received data packet. However, even when the above specific conditions are not met (for example, the core network (CN) does not send at least one of the PSDB, PSER, and PSIHI to the RAN, or the RAN refuses to accept any of the PSDB, PSER, and PSIHI), there are still some scenarios where the RAN needs the PDU Set information corresponding to the data packet. For example, if the RAN is congested, the RAN wants to perform packet loss based on PDU Set Importance (PSI), such as discarding data packets in less important PDU Sets. Therefore, the following problems need to be solved:

[0199] Question 1: For data flows, if the core network equipment supports marking the PDU Set information on the packet header but does not mark it (for example, PSER, PSDB, and PSIHI are rejected by the RAN, and the core network equipment does not mark the PDU Set information on the packet header of the data packet in the QoS flow; for example, the application function (AF) does not request PDU Set QoS processing for the data flow, and the core network equipment does not mark the PDU Set information on the packet header of the data packet in the QoS flow), but the RAN needs the PDU Set information of the data packet (for example, in the event of congestion, the RAN wants to drop packets based on the PSI), the problem of how to activate the PDU Set information marking on the packet header needs to be solved.

[0200] Problem 2: Core network devices rely on protocol descriptors to mark packet headers with PDU Set information. If this protocol information is not present, the core network devices or QoS flows may not support this feature. In this scenario, if the RAN is unaware of this and requests the core network devices to activate this feature, it will always fail.

[0355] Alternatively, the allowing activation of the operation on the data packet mark PDU Set information indicates: allowing the operation on the activation data packet mark PDU Set information in the first object;

[0356] Or, PDU Set processing is allowed means: PDU Set processing of the first object is allowed;

[0357] Or, the data packet does not mark the PDU Set information, indicating that: the data packet in the first object does not mark the PDU Set information;

[0358] Or, the first communication device needs PDU Set information, which indicates that the first communication device needs PDU Set information of the first object;
