[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on February 7, 2024, with application number 202410175383.X and invention name “Data processing method and device, information processing method and device, communication equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

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

[0004] At present, when the User Plane Function (UPF) uses the Packet Detection Rule (PDR) to perform packet detection on downlink data, if the UPF receives a data packet and the data packet does not belong to the PDU Set identified by the Protocol Data Unit Set (PDU Set) according to the Protocol Description (Protocol Description), the UPF will still map the data packet to the PDU Set and determine the PDU Set information. This will cause the PDU Set to transmit data packets that should not be transmitted. In this case, parameters such as the PDU Set size and the number of PDUs in the PDU Set may also be incorrect.

[0119] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0120] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects, for example, the first object can be one or more. In addition, "or" in this application represents at least one of the connected objects. For example, "A or B" covers three options, namely, Option 1: including A but not including B; Option 2: including B but not including A; Option 3: including both A and B. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0121] The term "indication" in this application can be either a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0122] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) or other systems. 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. thGeneration, 6G) communication system.

[0123] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0124] Downlink data may belong to a PDU set, or may not belong to any PDU Set (for example, an independent PDU). According to relevant technologies, when the UPF uses PDR to perform packet detection on the downlink data, if the UPF receives a Protocol Data Unit (PDU) and the PDU does not belong to the PDU Set identified by the Protocol Description (Protocol Description), the UPF (for example, it can be a PDU Session Anchor (PSA)) still maps it to the PDU Set and determines the PDU Set information. This type of PDU will be referred to as a specific PDU later. The disadvantage of this approach is that the length of the PDU Set delay budget (PSDB) is greater than the packet delay budget (PDB). Using PSDB to determine the delay budget of a specific PDU will exceed the PDB.

[0125] Some parameters, such as the PDU set size and the number of PDUs in the PDU set, require negotiation between the access stratum (AS) and the network. If the network-side UPF detects that a PDU does not belong to a PDU set (based on the Protocol Description in PDR), it will still map the data packet into a PDU set. This will cause the PDU set to transmit data packets that should not be transmitted. Parameters such as the PDU set size and the number of PDUs in the PDU set may also be incorrectly calculated.

Similarly, applying a second QER to the first data packet can be understood as performing a QoS execution operation corresponding to a second QER identifier (QER ID) on the first data packet, wherein the QoS operation is to map the first data packet to a second QoS flow, or the QoS operation is to, after the QoS operation is performed on the first data packet, the QoS (e.g., uplink and downlink rates, packet delay) of the data packet is the same as the QoS of the data packets in the second QoS flow (i.e., the QoS parameters of the first data packet and the data packets in the second QoS flow are the same).

[0180] In some embodiments, the first QoS enforcement rule (QER) and the second QER are both associated with a first packet detection rule (PDR).

[0181] In some embodiments, the first PDR includes the first QER and the second QER.

[0187] Exemplary purposes of the protocol description information or protocol description include: indicating the service data stream (e.g., Real-time Transport Protocol (RTP) or Secure Real-time Transport Protocol (SRTP)) and the transport protocol used by the information. Exemplary purposes of the protocol description include identifying PDUs in the data stream that belong to a PDU set.

[0195] Exemplarily, when the second condition is met, the first data packet may match all parameters in the packet detection information (PDI) except the protocol description information, but does not match the protocol description.

[0216] For example, the QoS parameters of a QoS flow can be understood as the parameters or indicators specified in the QoS parameters for packets in the QoS flow. For example, if the QoS parameters specify an uplink rate of 100 Mbps, then the packets in the QoS flow also have an uplink rate of 100 Mbps.

[0217] In some embodiments, the second QoS flow is a QoS flow that satisfies at least one of the following:

[0449] AF session QoS creation request (Nnef_AFsessionWithQoS_Create request);

[0450] In one implementation, two AFs respectively send two AF session QoS update requests or AF session QoS creation requests to the same PCF (for example, two AFs respectively send two AF session QoS update requests or AF session QoS creation requests to the NEF, and the NEF then sends two policy verification update requests or policy verification creation requests to the same PCF):

[0477] In one embodiment, when the data flow related information sent by the AF and received by the PCF includes two sets of QoS for a data flow, the PCF generates two PCC rules. The PCF generates PCC rule 1 based on the QoS parameters at the PDU set granularity and generates PCC rule 2 based on the QoS parameters at the PDU granularity. The service data flow detection, or service data flow template, in PCC rule 1 is the same as the service data flow detection, or service data flow template, in PCC rule 2.

[0478] In one embodiment, after the PCF receives requests sent by two AFs respectively, if the data flow related information in the two AF requests is the same, the PCF performs at least one of the following:

[0479] Generate a PCC rule, where the PCC rule includes at least one of the following: data flow detection information, protocol description information, information for requesting to perform the first operation, QoS parameters at a PDU aggregate granularity, and QoS parameters at a PDU granularity; the reason for generating the PCC rule is that the data flow detection information aggregated by the two AF requests is the same;
