[0134] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. Those skilled in the art can know that the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems as the system architecture evolves and new business scenarios appear.

[0135] The following embodiments of the present disclosure can be applied to Figure 1A the communication system 100 shown or part of the communication system 100, but are not limited thereto. Figure 1A Each of the subjects shown is an example, and the communication system 100 can include Figure 2 all or part of the subjects in Figure 2 , or other subjects other than . The number and form of each subject are arbitrary, each subject can be physical or virtual, the connection relationship between each subject is an example, each subject can not be connected or can be connected, and the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0136] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0137] In some cases, mobile media type services, XR services such as online AR / VR, online games, video-based machine or drone remote control, etc. are expected to contribute to an increasingly high traffic for the communication network. XR services involve multi-modal data flows. Multi-modal data is data input from the same device or different devices (including sensors) that describe the same service / application, which can be output to one or more destination device terminals. Each data flow in multi-modal data often has certain or even strong correlation, such as synchronization of audio and video streams, synchronization of haptics and vision, etc. There are some common characteristics in the data flow of such media services, between the data flows, and the requirements of these service data flows for network transmission. Effective identification and utilization of these characteristics will be more helpful for network and service transmission, control, and also for service guarantee and user experience.

[0138] In further cases, XRM services and interactive media type services (eXtended Reality and interactive media services) require the communication system to comprehensively consider the QoS characteristics of service data flows. The QoS characteristics include, for example, at least one of the following: whether delay-sensitive guaranteed bit rate (GBR) data flows, guaranteed flow bit rate (GFBR), packet delay budget (PDB), default maximum data burst volume (MDBV), etc. can be simultaneously satisfied and consistently coordinated. The consistency of QoS authorization and execution of each other for multiple XRM data flows involving one terminal and XRM data flows involving multiple terminals is guaranteed.

[0139] In some embodiments, the service data flow (SDF) of XRM can support PDU set-based processing, thereby enhancing QoS awareness and guarantee of SDF and enhancing the quality of experience (QoE) of users.

[0140] In some embodiments, in a system such as 4G, 5G, 6G, V2X, the AF can provide PDU set QoS parameters and protocol description. In some embodiments, the PDU set QoS parameters can include at least one of: PDU set delay budget (PSDB), PDU set error rate (PSER), PDU Set Integrated Handling Information (PSIHI). Then, the SMF and UPF can extend the packet header of the PDU in the PDU set of the SDF in combination with the protocol description and protocol header extension provided by the AF to carry PDU set information. The carried PDU information can be used for the access network to perform PDU set based QoS control.

[0141] In some embodiments, the above-mentioned PDU set information can include at least one of: PDU set sequence number, starting PDU or ending PDU of the PDU set, PDU sequence number within the PDU set, PDU number within the PDU set, PDU set importance, PDU set size. Here, the PDU set importance is used to represent the importance of a PDU set relative to other PDU sets in the same QoS flow.

[0142] It can be understood that the UPF performs SDF to QoS flow mapping based on the PDR, and maps (also can be called encapsulates) the mutually associated PDUs into a PDU set. In addition, the UPF can apply the same QoS policy to all PDU sets in the QoS flow. For example, the UPF can apply the same PDU set QoS parameters to all PDU sets in the QoS flow. In an example, the UPF can map the application flow to the QoS flow based on the packet detection information in the PDR. Some PDUs in the QoS flow can be associated with media components (e.g., intra-coded frames and predicted frames), and the UPF classifies these PDUs as belonging to a PDU set and performs corresponding control. In some embodiments, the RAN can implement PDU set based processing according to the PDU set specific QoS characteristics and protocol description provided by the 5GC and AF, and the enhanced header identified and marked by the UPF.

[0143] In some embodiments, traffic characteristics of a service data flow (SDF) on a user plane can dynamically change. For example, the SDF can experience data burst. In response to the dynamic change of the traffic characteristics of the SDF, data boost handling can be considered. In the case of applying data boost handling, a packet filter set can be enhanced to detect an expedited transfer indication in a packet on the user plane.

[0144] In some embodiments, two policy and charging control (PCC) rules can be authorized for one SDF. The two PCC rules have different identification information and different QoS authorization. The two PCC rules can be respectively bound to different QoS flows and correspond to different QoS flow identifiers (QFIs). In some embodiments, the QoS flow bound by one PCC rule can have a higher priority and / or better QoS characteristics, and can be used to implement data boost handling of the SDF; the QoS flow bound by the other PCC rule can have a lower priority and / or normal QoS characteristics, and can be used to implement normal handling (or non-data boost handling) of the SDF. In some embodiments, in the case of performing data boost handling, the packets of the SDF can be switched from the QoS flow with the higher priority and / or better QoS characteristics to the QoS flow with the lower priority and / or normal QoS characteristics, which can be referred to as QoS promotion. In some embodiments, in the case of ending data boost handling, the packets of the SDF can be switched from the QoS flow with the lower priority and / or normal QoS characteristics to the QoS flow with the higher priority and / or better QoS characteristics, which can be referred to as QoS fallback. It can be understood that the above-mentioned QoS promotion and QoS fallback can be collectively referred to as QoS switching related to data boost handling.

[0145] In some embodiments, the SDF can have different QoS requirements according to different actual situations. Therefore, how to implement corresponding data boost handling according to the specific requirements of the SDF is a technical problem to be solved.

[0146] Figure 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. The communication method related by the embodiment of the present disclosure can be applied to the communication system 100. As shown in Figure 3A , the communication method of the embodiment of the present disclosure includes steps S201 to S210.

[0147] In step S201, the fourth network element 1034 sends first indication information to the first network element 1031.

[0153] In some embodiments, the first SDF can include a plurality of sub-flows. For example, the first SDF can be a composite data stream composed of a plurality of data streams, each of which is a sub-flow of the composite data stream. In some embodiments, a sub-flow in the first SDF can have its own QoS requirement. This means that the QoS requirement of the sub-flow can be different from the first SDF, or different from other sub-flows in the first SDF.

[0154] In some embodiments, the first indication information can be used to indicate to perform data acceleration processing on a first sub-flow of the first SDF. In some embodiments, the first indication information can be used to determine a QoS policy related to the data acceleration processing of the first sub-flow of the first SDF.

[0155] In some embodiments, the name of the first indication information is not limited, which can be, for example, an acceleration transfer indication, an acceleration processing indication, a QoS improvement indication, etc.

[0157] In some embodiments, the fourth network element 1034 can be an AF, and the first network element 1031 can be a PCF. In an example, the AF can send the first indication information directly to the PCF. In an example, the AF can send the first indication information to the NEF, and the NEF can send the first indication information to the PCF.

[0158] In some embodiments, the fourth network element 1034 can further send QoS requirements to the first network element 1031. In an example, the QoS requirements can be related to the first SDF, or can be related to the first sub-flow. In some embodiments, the QoS requirements can include requirements related to QoS characteristics of the first SDF or the first sub-flow of the first service, including transmission rate, latency, uplink and downlink direction, etc. The QoS requirements can be used to determine QoS-related policies and / or rules for the first SDF or the first sub-flow.

[0159] In some embodiments, the first indication information and / or the QoS requirements can be used by the first network element 1031 to implement authorization and identification of data acceleration processing.

[0160] In some embodiments, the fourth network element 1034 can further send at least one of the following to the first network element 1031: an identifier of the first service, an address and / or an identifier of the terminal 101, an identifier of the first network element 1031, an application identifier of the first service, a flow description, a data network name (DNN), single network slice selection assistance information (S-NSSAI), and a QoS parameter.

[0161] In step S202, the first network element 1031 performs policy decision.

[0162] In some embodiments, the first network element 1031 can perform policy decision to determine rules related to data acceleration processing for the first SDF.

[0163] In some embodiments, the performance of policy decision by the first network element 1031 can take into account the first indication information. In some embodiments, the policy decision by the first network element 1031 can be implemented according to at least the first indication information. In some embodiments, upon receiving the first indication information, the first network element 1031 can determine rules related to data acceleration processing for the first SDF, taking into account the first indication information.

[0164] In some embodiments, the rules related to the data acceleration processing can comprise a first rule and a second rule. In some embodiments, the data acceleration processing can be for a first SDF. In an example, both the first rule and the second rule can be rules authorized by the first network element 1031 for the first SDF. In some embodiments, the data acceleration processing can be for a first sub-flow of the first SDF. In an example, both the first rule and the second rule can be rules authorized by the first network element 1031 for the first sub-flow.

[0165] In some embodiments, each of the first rule and the second rule determined by the first network element 1031 can be a PCC rule. It can be appreciated that the first rule and the second rule can also be other rules, which are not limited in the embodiments of the present disclosure.

[0166] In some embodiments, the first rule can correspond to an acceleration processing of the first SDF or the first sub-flow. In some embodiments, the QoS characteristics corresponding to the first rule can be applied to the first SDF or the first sub-flow in the process of performing the data acceleration processing for the first SDF.

[0167] In some embodiments, the second rule can correspond to a normal processing of the first SDF or the first sub-flow. In some embodiments, the QoS characteristics corresponding to the second rule can be applied to the first SDF or the first sub-flow in the process of not performing the data acceleration processing for the first SDF.

[0168] In some embodiments, the first rule and the second rule can be bound to different QoS flows. The different QoS flows can have different QoS characteristics. The QoS flow bound by the first rule can be used for the data acceleration processing of the first SDF or the first sub-flow. The QoS flow bound by the second rule can be used for the normal processing (or basic processing) of the first SDF or the first sub-flow.

[0169] In some embodiments, the QoS flow bound by the first rule can have a higher priority and / or higher QoS characteristics compared to the QoS flow bound by the second rule.

[0170] In some embodiments, the first rule and the second rule related to the data acceleration processing can be associated. In other words, the first rule and the second rule can constitute a rule pair related to the data acceleration processing. In this rule pair, the first rule and the second rule can be considered as two peer rules for the first SDF. For example, the first rule can be a peer rule of the second rule. For example, the second rule can be a peer rule of the first rule.

In some embodiments, the first network element 1031 can send the first rule and the second rule to the second network element 1032. The first rule and / or the second rule can comprise the second information. It can be understood that the second information can also be independent of the first rule and the second rule, and be sent by the first network element 1031 separately, or together with the first rule and the second rule.

[0184] In step S204, the second network element 1032 determines the QoS related rules.

In some embodiments, the second network element 1032 can perform the QoS flow binding and the determination of the QoS related rules with consideration of the second information.

[0195] In some embodiments, the first information is used for QoS mapping of the first SDF or the first sub-flow.

[0196] It can be understood that the QoS mapping refers to carrying data bearers in a data flow in a QoS flow. For example, the QoS mapping for the first SDF can be carrying data bearers of the first SDF in a corresponding QoS flow.

[0210] In some embodiments, the second identification information can be used to identify an association between the first rule and the second rule. The second identification information can be used to determine that the first rule and the second rule are two associated rules for the first SDF or the first sub-flow.

[0211] In some embodiments, the second indication information can be used to trigger a reflective QoS mechanism for a first SDF or the first sub-flow in the QoS flow mapped to the first rule binding. In some embodiments, the second indication information can be used to indicate adding a reflective QoS indication (RQI) for a data packet in the first SDF or the first sub-flow using data acceleration processing. In some embodiments, the second indication information can be used to indicate data acceleration processing for uplink of the first SDF or the first sub-flow. In some embodiments, the second indication information can be used to implement data acceleration processing for uplink data packets in the first SDF or the first sub-flow.

[0212] In some embodiments, the reflective QoS mechanism (or referred to as reflective QoS) enables the terminal 101 to map uplink user plane traffic to a QoS flow in the case that the second network element 1032 does not provide a QoS rule. In some embodiments, in the reflective QoS mechanism, the terminal 101 can determine a QoS rule for uplink traffic based on received downlink traffic. Then, the terminal 101 can use the determined QoS rule to determine the mapping of the uplink traffic to the QoS flow. In an example, the third network element 1033 can set an RQI in the header of a downlink data packet in the first SDF or the first sub-flow, and then the terminal 101 can determine a QoS rule corresponding to the downlink data packet according to the RQI in the received downlink data packet, and implement uplink QoS mapping.

[0226] In some embodiments, the data packet can include a data packet in a first SDF of a first service.

[0227] In some embodiments, the data packet can include a data packet in a first subflow of the first SDF of the first service.

[0228] In some embodiments, the data packet can be transmitted on a user plane through an N6 interface.

[0229] In some embodiments, the header of the data packet can carry the first indication information.

[0230] In step S208, the third network element 1033 performs QoS mapping.

[0231] In some embodiments, the third network element 1033 can perform detection and mapping processing on the received downlink data packet of the first SDF.

[0232] In some embodiments, the third network element 1033 can identify the first indication information in the packet header of the downlink data packet of the first SDF by detection.

[0233] In some embodiments, the step S208 can include that the third network element 1033 performs data acceleration processing related to the first SDF or the first sub-flow. In some embodiments, the data acceleration processing can include QoS promotion of the first SDF, QoS fallback of the first SDF, QoS promotion of the first sub-flow, or QoS fallback of the first sub-flow.

[0234] In some embodiments, the third network element 1033 can determine, according to the first information, that the data acceleration processing is applied to the first SDF or the first sub-flow. In an example, the first information includes at least one of the first identification information and the first description information, and the data acceleration processing is applied to the first sub-flow. In an example, the first information does not include the first identification information and the first description information, and the data acceleration processing is applied to the first SDF.

[0235] In some embodiments, the direction of the data acceleration processing of the first SDF can include uplink and / or downlink.

[0236] In some embodiments, in the case that the first indication information is detected in the packet header of the downlink data packet of the first SDF, the third network element 1033 can determine to perform the data acceleration processing on the first SDF. In some embodiments, in the case that the first indication information is detected in the packet header of the downlink data packet of the first SDF, the third network element 1033 can determine to perform the data acceleration processing on the downlink data packet of the first SDF.

[0237] In some embodiments, in the case that the first indication information is detected in the packet header of the downlink data packet of the first sub-flow, the third network element 1033 can determine to perform the data acceleration processing on the first sub-flow. In some embodiments, in the case that the first indication information is detected in the packet header of the downlink data packet of the first sub-flow, the third network element 1033 can determine to perform the data acceleration processing on the downlink data packet of the first sub-flow.

[0238] In some embodiments, the first sub-flow can be non-encrypted.

[0239] In some embodiments, the first sub-flow can be encrypted. At this time, according to the first identification information and / or the first description information in the first information, the third network element 1033 can detect the downlink data packet of the first sub-flow. In an example, the first identification information and / or the first description information can be carried in the packet header of the downlink data packet of the first sub-flow, and the third network element 1033 can detect the downlink data packet of the first sub-flow according to the first identification information and / or the first description information in the first information.

[0240] In some embodiments, to implement the data acceleration processing, the third network element 1033 can switch the first SDF or the first sub-flow from the second QoS flow to the first QoS flow. In some embodiments, the third network element 1033 can switch the data packet of the first SDF or the first sub-flow from the second QoS flow to the first QoS flow. In an example, the third network element 1033 can switch the QFI corresponding to the data packet of the first SDF or the first sub-flow from the second QFI to the first QFI.

[0241] In some embodiments, the first QFI corresponds to the first QoS flow. The first QFI can indicate the QoS characteristics of the first QoS flow.

[0242] In some embodiments, the second QFI corresponds to the second QoS flow. The second QFI can indicate the QoS characteristics of the second QoS flow.

[0243] In some embodiments, the first rule-bound QoS can have a higher priority and / or better QoS characteristics than the second rule-bound QoS flow. In some embodiments, the first QoS can have a higher priority and / or better QoS characteristics than the second QoS flow.

[0244] In some embodiments, the third network element 1033 can determine, according to the second identification information, that the first QoS flow and the second QoS flow are associated. Then, in a case where it is determined to perform the data acceleration processing on the first SDF or the first sub-flow in a downlink direction, the third network element 1033 can determine to switch the first SDF or the first sub-flow from the second QoS flow to the first QoS flow.

[0245] In some embodiments, in a case where it is determined to perform the data acceleration processing on the first SDF or the first sub-flow in an uplink direction, the third network element 1033 can mark the RQI in the downlink data packet of the first SDF or the first sub-flow. At this time, the first SDF or the first sub-flow is mapped to the first QoS flow. In some embodiments, in a case where it is determined to perform the data acceleration processing on the uplink data packet of the first SDF or the first sub-flow according to the second indication information, the third network element 1033 can mark the RQI in the downlink data packet of the first SDF or the first sub-flow. In an example, in a case where the second indication information is received, the third network element 1033 can mark the RQI in the downlink data packet of the first SDF or the first sub-flow mapped to the first QoS flow.

[0246] In some embodiments, the third network element 1033 can determine that the data acceleration processing for the first SDF or the first sub-flow is no longer performed. In an example, the data acceleration processing for the first SDF or the first sub-flow can end. In some embodiments, the first indication information can no longer be carried in the packet header of the downlink data packet of the first SDF or the first sub-flow, and the third network element 1033 can determine that the data acceleration processing for the first SDF or the first sub-flow is no longer performed. In some embodiments, a timer for the data acceleration processing expires, and the third network element 1033 can determine that the data acceleration processing for the first SDF or the first sub-flow is no longer performed.

[0247] In some embodiments, after the data acceleration processing ends, the third network element 1033 can switch the first SDF or the first sub-flow from the first QoS flow to the second QoS flow. In some embodiments, the third network element 1033 can switch the data packet of the first SDF or the first sub-flow from the first QoS flow to the second QoS flow. In an example, the third network element 1033 can switch the QFI corresponding to the data packet of the first SDF or the first sub-flow from the first QFI to the second QFI.

[0248] In some embodiments, the third network element 1033 can determine that the first QoS flow and the second QoS flow are associated according to the second identification information. Then, in a case where it is determined that the data acceleration processing for the downlink of the first SDF or the first sub-flow ends, the third network element 1033 can determine that the first SDF or the first sub-flow is switched from the first QoS flow to the second QoS flow.

[0249] In some embodiments, the first indication information can be used to implement the QoS optimization processing of the first sub-flow. In some embodiments, the first indication information can be used to indicate that the first sub-flow has a higher QoS requirement. In some embodiments, the QoS optimization processing of the first sub-flow can include QoS classification matching for the first sub-flow. In some embodiments, in a case where the first SDF includes multiple sub-flows, multiple sets of QoS characteristics (corresponding to multiple QoS flows) can be used to implement the classification processing of the multiple sub-flows. Different sub-flows can be different in terms of QoS requirements, QoS parameters, flow characteristics, service characteristics, etc. Then, different sub-flows can be matched to different QoS characteristics or QoS flows. In this case, the first indication information can be used to implement the QoS matching of the first sub-flow. The QoS matching can refer to the matching between the QoS requirement and the QoS characteristic or the QoS flow. For example, the first indication information can be used to match the first sub-flow to a higher QoS characteristic. This means that the first sub-flow is mapped to a QoS flow with a higher priority and / or a higher QoS characteristic.

[0250] In step S209, the third network element 1033 sends the data packet to the terminal 101.

[0251] In some embodiments, the third network element 1033 can send the data packet. In some embodiments, the data packet can be sent by the third network element 1033, but is not limited thereto, and can also be sent by other subjects.

[0252] In some embodiments, the terminal 101 can receive the data packet. In some embodiments, the data packet can be received by the terminal 101, but is not limited thereto, and can also be received by other subjects.

[0253] In some embodiments, in the case that the first SDF or the first subflow adopts data acceleration processing in the downlink, the third network element 1033 can map the data packet to the first QoS flow and send.

[0254] In some embodiments, in the case that the first SDF or the first subflow adopts data acceleration processing in the uplink, the third network element 1033 can mark the RQI in the data packet and send through the first QoS flow.

[0255] In some embodiments, in the case that the data acceleration processing of the first SDF or the first subflow ends, the third network element 1033 can map the data packet to the second QoS flow and send.

[0256] In some embodiments, the third network element 1033 can send the data packet to the terminal 101 via the access network device 102.

[0257] In step S210, the terminal 101 sends the data packet to the fifth network element 1035.

[0258] In some embodiments, the terminal 101 can send the data packet. In some embodiments, the data packet can be sent by the terminal 101, but is not limited thereto, and can also be sent by other subjects.

[0259] In some embodiments, the fifth network element 1035 can receive the data packet. In some embodiments, the data packet can be received by the fifth network element 1035, but is not limited thereto, and can also be received by other subjects.

[0260] In some embodiments, the terminal 101 can send the data packet to the fifth network element 1035 through the third network element 1033.

[0261] In some embodiments, the terminal 101 can perform data acceleration processing related to the first SDF or the first subflow.

[0262] In some embodiments, the data acceleration processing can include: QoS promotion of the first SDF, QoS fallback of the first SDF, QoS promotion of the first subflow, and QoS fallback of the first subflow.

[0263] In some embodiments, terminal 101 can determine whether data acceleration processing is applied to a first SDF or a first substream based on first information. In one example, if the first information includes at least one of first identification information and first description information, then the data acceleration processing is applied to the first substream. In another example, if the first information does not include first identification information and first description information, then the data acceleration processing is applied to the first SDF.

[0264] In some embodiments, the direction of the first SDF's data acceleration processing is uplink.

[0265] In some embodiments, to accelerate data processing, terminal 101 can switch the first SDF or the first sub-stream from the second QoS stream to the first QoS stream. In some embodiments, terminal 101 can switch the data packets of the first SDF or the first sub-stream from the second QoS stream to the first QoS stream. In one example, terminal 101 can switch the QFI corresponding to the data packets of the first SDF or the first sub-stream from the second QFI to the first QFI.

[0266] In some embodiments, the QoS bound by the first rule may have a higher priority and / or better QoS characteristics than the QoS flow bound by the second rule.

[0267] In some embodiments, terminal 101 can determine that the first QoS stream and the second QoS stream are associated based on the second identification information. Then, if it is determined that uplink data acceleration processing is to be performed on the first SDF or the first sub-stream, terminal 101 can determine that the first SDF or the first sub-stream switches from the second QoS stream to the first QoS stream.

[0268] In some embodiments, terminal 101 may determine that it will no longer perform data acceleration processing on the first SDF or the first substream. In one example, data acceleration processing on the first SDF or the first substream may end. In some embodiments, if a timer for data acceleration processing in terminal 101 times out, terminal 101 may determine that it will no longer perform uplink data acceleration processing on the first SDF or the first substream.

[0269] In some embodiments, after the data acceleration processing is completed, terminal 101 can switch the first SDF or the first sub-stream from the first QoS stream to the second QoS stream. In some embodiments, terminal 101 can switch the data packets of the first SDF or the first sub-stream from the first QoS stream to the second QoS stream. In one example, terminal 101 can switch the QFI corresponding to the data packets of the first SDF or the first sub-stream from the first QFI to the second QFI.

[0270] In some embodiments, the terminal 101 can determine, according to the second identification information, that the first QoS flow and the second QoS flow are associated. Then, in a case where it is determined that the data acceleration processing for the downlink of the first SDF or the first sub-flow ends, the terminal 101 can determine that the first SDF or the first sub-flow is switched from the first QoS flow to the second QoS flow.

[0271] In some embodiments, the data packet sent by the terminal 101 can include the uplink data packet of the first SDF or the first sub-flow.

[0272] In some embodiments, the RQI can be carried in the header of the downlink data packet received by the terminal 101 from the third network element 1033. At this time, the terminal 101 can implement the sending of the uplink data packet by using the QoS characteristics corresponding to the QoS characteristics of the downlink data packet.

[0273] In some embodiments, the downlink data packet of the first SDF or the first sub-flow received by the terminal 101 can be in the first QoS flow, and the RQI can be carried in the header of the downlink data packet. At this time, the terminal 101 can map the uplink data packet of the first SDF or the first sub-flow to the first QoS flow. It can be understood that the first QoS flow to which the uplink data packet is mapped and the first QoS flow to which the downlink data packet is mapped can be the same QoS flow, or can be two QoS flows with the same or related QoS characteristics.

[0274] In some embodiments, multiple data acceleration processes can be performed for the first SDF. In some embodiments, in the implementation process of the first service, the first SDF can undergo multiple QoS promotions (i.e., switching to the first QoS flow) and multiple QoS backfalls (i.e., switching back to the second QoS flow). In some embodiments, after the data acceleration processing for the first SDF ends, the data acceleration processing for the first SDF can be performed again.

[0275] In some embodiments, after the data acceleration processing of the first SDF ends through the above steps S201 to S210, the third network element 1033 can switch the first SDF from the first QoS flow to the second QoS flow. After that, the third network element 1033 can detect whether the downlink data packet of the first SDF received subsequently carries the first indication information, to determine whether to perform data acceleration processing on the first SDF again. In some embodiments, after the data acceleration processing of the first SDF ends and the first SDF is switched to the second QoS flow, the third network element 1033 can detect the first indication information in the downlink data packet of the first SDF subsequently. At this time, the third network element 1033 can perform data acceleration processing on the first SDF again. The first SDF can be switched from the second QoS flow to the first QoS flow. The process of the data acceleration processing of the first SDF performed by the third network element 1033 again can refer to the description of the above steps S201 to S210, which will not be described here.

[0312] In the following, the embodiments of the disclosure are exemplarily explained through specific embodiments.

[0313]

[0314] ​​In some embodiments, the present disclosure implements enhanced packet filter settings (i.e., first information) to support data acceleration processing. The enhanced packet filter settings include an acceleration transfer indication.

[0315] In some embodiments, the enhanced packet filter with the acceleration transfer indication can be used in QoS rules (implementing uplink flow detection and QoS flow mapping for a UE) and PDRs (implementing downlink flow detection and QoS flow mapping for a UPF) to identify one or more packet flows.

[0316] In some embodiments, in data acceleration processing, QoS promotion for uplink non-GBR (non-GBR) flows can be implemented by reflective QoS.

[0317] In some embodiments, for data acceleration functions for one or more subflows in a composite data flow, subflow identification or media flow description information can be included in the enhanced packet filter settings along with the acceleration transfer indication. In some embodiments, data acceleration processing for subflows can support encrypted and non-encrypted scenarios.

[0318] In some embodiments, for IP PDU session types, packet filter settings support for packet filters can be based on at least one of the following: source / destination IP address or IPv6 prefix; source / destination port number; protocol identification of IP / next header type protocol; type of service (ToS) (IPv4) / traffic class (IPv6) and mask; flow label (IPv6); security parameter index; packet filter direction; acceleration transfer indication (i.e., first indication information); subflow identification (i.e., first identification information) or media flow description information (i.e., first description information).

[0319] In some embodiments, the acceleration transfer indication can indicate data acceleration and higher QoS requirements. Then, in the case of detecting the acceleration transfer indication, a higher QoS flow bound to a PCC rule with a higher QoS authorization can be applied; in the case of not detecting the acceleration transfer indication, a lower QoS flow bound to a PCC rule with a lower QoS authorization can be applied.

[0320] In some embodiments, the subflow identification or media flow description information can indicate a composite data flow with multiple QoS requirements and / or multiple QoS authorizations.

[0321] In some embodiments, the subflow identification or media flow description information can be included in the packet filter settings along with the acceleration transfer indication to support data acceleration traffic for one or more subflows in a composite data flow.

[0322] In some embodiments, the subflow identification can be a track identification in the MoQ protocol, a flow identification in the QUIC protocol, etc.

[0323] In some embodiments, the media stream description information can be a protocol type, or a feature field in the protocol type, e.g., an RTP SSRC, an RTP payload type, to indicate different QoS requirements.

[0324] Figure 5 is an interaction schematic diagram of an exemplary implementation of a communication method according to embodiments of the present disclosure. In some embodiment sets, the communication method can involve a process in which an AS requests a 5GS to upgrade QoS by using a reflective QoS feature, or a process in which an AS supports a communication system to perform a QoS-specific optimization process, e.g., a QoS classification matching process, by using multiple sets of QoS features.

[0325] As shown in Figure 5 , the communication method includes steps S401 to S406.

[0326] In step S401, a PDU session establishment process and an AF session request process for a QoS requirement of an SDF are performed.

[0327] In some embodiments, an AF (i.e., a fourth network element) provides an expedited transfer indication (i.e., first indication information) and a QoS requirement to a PCF (i.e., a first network element) (directly or through a NEF) to assist in authorization and identification of data acceleration (e.g., determining two PCC rules for data acceleration of an SDF or data acceleration of a subflow of a composite SDF). An IP packet filter can have the expedited transfer indication and can include a subflow identification or media stream description information, and can also include an associated identification of a PCC rule (i.e., second identification information), and use these information to help a UPF identify downlink PDUs and map to corresponding QoS flows.

[0328] In some embodiments, the PCF can include the expedited transfer indication in one or two authorized PCC rules (i.e., a first rule and / or a second rule) to a SMF (i.e., a second network element) to request identification and switching of traffic enabled for data acceleration.

[0329] In some embodiments, a PCC rule can be enhanced to support the expedited transfer indication, and can also support a subflow identification or media stream description information, and can also support an associated identification of a PCC rule. These information can be used to help a UPF identify downlink PDUs and map to corresponding QoS flows, and can be sent by the PCF to the SMF.

[0330] In some embodiments, based on the acceleration transfer indication in the PCC rule, and / or local configuration, the SMF performs the binding of two PCC rules to two QoS flows, and generates the QoS rules, QoS profile and N4 rules. The acceleration transfer indication, (optionally) support of sub-flow identification or media flow description information, (optionally) associated identification of PCC rules can be provided in the QoS rules and / or N4 rules for SDF detection when data acceleration or sub-flow detection of composite SDF when data acceleration.

[0331] In some embodiments, with the consideration of the acceleration transfer indication, (optionally) support of sub-flow identification or media flow description information, (optionally) associated identification of PCC rules, the SMF instructs the UPF to identify and enable data acceleration, e.g. perform QoS flow mapping for downlink direction.

[0332] In some embodiments, for the traffic triggering and identified for data acceleration, a second non-GBR 5QI is configured with a higher priority value and better QoS compared to the normal 5QI of the first PCC rule with non-data acceleration authorization.

[0333] In some embodiments, according to the instruction of the SMF, for downlink direction, the IP packet filter settings with acceleration transfer indication, (optionally) support of sub-flow identification or media flow description information, (optionally) associated identification of PCC rules can be used by the UPF (i.e. third network element) for SDF detection when data acceleration or sub-flow detection of composite SDF when data acceleration and mapping to QoS flow.

[0334] In step S402 (including step S402a and step S402b), after the PCC and QoS authorization, the binding of PCC rules to QoS flows, the UE (i.e. terminal) sends uplink data to the AS (i.e. fifth network element) or receives downlink data from the AS. The UE can use the authenticated QoS flow or the default QoS flow.

[0335] In step S403 (including step S403a and step S403b), based on the application requirement in the AS, the AS instructs the UE to send data files (e.g. video, picture) with higher resolution. Because the AS finds that the data volume from the UE will be larger and the timely reception of this information is critical for the application, the AS can include this request in the metadata to accelerate the data transfer to the 5GS.

[0336] In some embodiments, the AS can provide the acceleration transfer indication to the UPF. The acceleration transfer indication is carried in the N6 PDU header of the downlink SDF.

[0337] In step S404, for the downlink direction, the IP packet filter settings with the accelerated transfer indication, (optionally) supporting subflow identification or media flow description information, (optionally) the associated identification of PCC rules are used by the UPF for the detection of SDFs or subflows of composite SDFs at data acceleration time and mapping to QoS flows when data acceleration.

[0338] In some embodiments, the UPF switches the SDF from the first QFI to a second QFI with a higher priority value and higher authorized QoS, and applies reflective QoS, in consideration of the enhanced IP packet filter settings. For example, the UPF switches the SDF from the first QFI to a second QFI with a higher priority value and higher authorized QoS to apply RQI marking to downlink PDUs of the SDF.

[0339] In some embodiments, the UPF switches the SDF from the higher QFI to the base QFI after the data acceleration processing ends, in consideration of the enhanced IP packet filter settings.

[0340] In some embodiments, the UPF can perform subsequent transfer of uplink and / or downlink by selecting the QoS flow with a higher quality 5QI (e.g., 5QI-6) established (in step S401).

[0341] In steps S405 and S406 (including steps S406a and S406b), for the uplink direction, the IP packet filter settings with the accelerated transfer indication, (optionally) supporting subflow identification or media flow description information, (optionally) the associated identification of PCC rules are used by the UE for the detection of SDFs or subflows of composite SDFs at data acceleration time and mapping to QoS flows.

[0342] In some embodiments, the UE switches the associated uplink SDF from the default QoS flow to the QoS flow of the second QFI with the RQI for transfer, in case of receiving a downlink data packet with the RQI.

[0343] In some embodiments, the UE can switch the associated uplink SDF from the QoS flow of the higher QFI to the default QoS flow for transfer, in case of the timer of reflective QoS expiring and / or no RQI marked in the downlink data packet.

[0344] In some embodiments, the IP packet filter settings with the expedited transfer indication, optionally supporting sub-flow identification or media flow description information, optionally the associated identification of PCC rules can be provided to the UPF by the PCF and the SMF. In some embodiments, the IP packet filter settings with the expedited transfer indication, optionally supporting sub-flow identification or media flow description information, optionally the associated identification of PCC rules can be provided to the UE by the PCF, the SMF, the AMF and the NG-RAN.
