[0135] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0136] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or some of the main components in the communication system 100, but are not limited thereto. The main components shown in FIG1A are illustrative. The communication system 100 may include all or some of the main components in FIG1A, or may include other main components other than those in FIG1A. The number and form of each main component are arbitrary. Each main component may be physical or virtual. The connection relationship between the main components is illustrative. The main components may not be connected or may be connected. The connection may be in any way, such as direct connection or indirect connection, wired connection or wireless connection.

[0137] The embodiments disclosed herein 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0138] In some cases, mobile media services, online AR / VR and other XR services, online games, and video-based remote control of machines or drones are expected to contribute increasingly higher traffic to communication networks. XR services involve multimodal data streams. Multimodal data describes data input from the same device or different devices (including sensors) for the same service / application, which may be output to one or more destination device terminals. The data streams in multimodal data often have a certain degree of correlation, or even a strong correlation, such as the synchronization of audio and video streams, or the synchronization of haptic and visual senses. The data streams of these media services themselves, the relationships between the data streams, and the network transmission requirements of these service data streams all share some common characteristics. Effective identification and utilization of these characteristics will be more conducive to network and service transmission and control, and will also contribute to service assurance and user experience.

[0139] In further scenarios, XRM services and eXtended Reality and interactive media services require communication systems to comprehensively consider the QoS characteristics of service data streams. These QoS characteristics include, for example, at least one of the following: whether parameters such as delay-sensitive guaranteed bit rate (GBR) data streams, guaranteed flow bit rate (GFBR), packet delay budget (PDB), and default maximum data burst volume (MDBV) can be simultaneously met and consistently maintained. This involves ensuring consistent QoS authorization and execution across multiple XRM data streams from a single terminal and across multiple terminals.

[0140] In some embodiments, the XRM service data flow (SDF) can be processed based on PDU sets, thereby enhancing QoS awareness and assurance of the SDF and improving the user's quality of experience (QoE).

[0141] In some embodiments, such as 4G, 5G, 6G, and V2X systems, the AF (Active Front-End) can provide PDU set QoS parameters and a protocol description. In some embodiments, the PDU set QoS parameters may include at least one of the following: PDU set delay budget (PSDB), PDU set error rate (PSER), and PDU set integrated handling information (PSIHI). Then, the SMF (Service Provider Framework) and UPF (User Provider Framework) can combine the protocol description and header extensions provided by the AF to extend the packet headers of the PDUs in the SDF's PDU set to carry PDU set information. The carried PDU information can be used by the access network for PDU set-based QoS control.

[0142] In some embodiments, the PDU set information may include at least one of the following: PDU set sequence number, the starting or ending PDU of the PDU set, the PDU sequence number within the PDU set, the number of PDUs within the PDU set, the importance of the PDU set, and the size of the PDU set. Here, the importance of the PDU set is used to characterize the importance of a PDU set relative to other PDU sets in the same QoS flow.

[0143] Understandably, the UPF performs SDF-to-QoS flow mapping based on the PDR and maps (or encapsulates) interrelated PDUs into a PDU set. Furthermore, the UPF can apply the same QoS policy to all PDU sets within the QoS flow. For example, the UPF can apply the same PDU set QoS parameters to all PDU sets within the QoS flow. In one example, the UPF can map the application flow to the QoS flow based on packet detection information in the PDR. Some PDUs in the QoS flow can be associated with media components (e.g., intra-coded frames and prediction frames), and the UPF classifies these PDUs as belonging to a PDU set and controls them accordingly. In some embodiments, the RAN can implement PDU set-based processing based on the PDU set-specific QoS features and protocol descriptions provided by 5GC and AF, as well as the enhanced headers identified and marked by the UPF.

[0144] In some embodiments, the traffic characteristics of the service data stream on the user plane may change dynamically. For example, the service data stream may experience data bursts. To address the dynamic changes in the traffic characteristics of the service data stream, data boosting handling can be considered. When applying data boosting handling, the packet filter set can be enhanced to detect expedited transfer indications in packets on the user plane.

[0145] In some embodiments, two policy and charging control (PCC) rules can be authorized for an SDF. These two PCC rules have different identification information and different QoS authorizations. These two PCC rules can be bound to different QoS flows and correspond to different QoS flow identifiers (QFIs). In some embodiments, the QoS flow bound to one PCC rule can have a higher priority and / or better QoS characteristics and can be used to implement data acceleration processing of the SDF; the QoS flow bound to the other PCC rule can have a lower priority and / or normal QoS characteristics and can be used to implement normal processing of the SDF (or non-data acceleration processing). In some embodiments, when performing data acceleration processing, SDF packets can switch from a QoS flow with higher priority and / or better QoS characteristics to a QoS flow with lower priority and / or normal QoS characteristics; this can be referred to as QoS enhancement. In some embodiments, when data acceleration processing ends, SDF packets can switch from a QoS flow with lower priority and / or normal QoS characteristics to a QoS flow with higher priority and / or better QoS characteristics; this can be referred to as QoS fallback. It is understandable that the aforementioned QoS upgrades and QoS fallbacks can be collectively referred to as QoS switching related to data acceleration processing.

[0146] In some embodiments, SDF may have different QoS requirements depending on the specific circumstances. Therefore, how to implement corresponding data acceleration processing for the specific needs of SDF is a technical problem that urgently needs to be solved.

[0147] Figure 2 is an interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in this embodiment can be applied to a communication system 100. As shown in Figure 2, the communication method of this embodiment includes steps S201 to S210.

[0148] In step S201, the fourth network element 1034 sends the first instruction information to the first network element 1031.

[0149] In some embodiments, the fourth network element 1034 may send first indication information. In some embodiments, the first indication information may be sent by the fourth network element 1034, but is not limited thereto, and may also be sent by other entities.

[0150] In some embodiments, the first network element 1031 may receive the first indication information. In some embodiments, the first indication information may be received by the first network element 1031, but is not limited thereto, and may also be received by other entities.

[0151] In some embodiments, the first indication information may be used to instruct the execution of data acceleration processing.

[0152] In some embodiments, the first indication information may be used to instruct data acceleration processing on the first SDF. In some embodiments, the first indication information may be used to determine a QoS policy related to the data acceleration processing of the first SDF.

[0153] In some embodiments, the first SDF may include the SDF of a first service. In some embodiments, the first service may include immersive communication services, extended reality multimedia (XRM) services, etc.

[0154] In some embodiments, the first SDF may include multiple sub-streams. For example, the first SDF may be a composite data stream consisting of multiple data streams, where each data stream is a sub-stream of the composite data stream. In some embodiments, the sub-streams in the first SDF may have their own QoS requirements. This means that the QoS requirements of a sub-stream may differ from those of the first SDF, or from those of other sub-streams in the first SDF.

[0155] In some embodiments, the first indication information may be used to instruct data acceleration processing to be performed on a first sub-stream of a first SDF. In some embodiments, the first indication information may be used to determine a QoS policy related to the data acceleration processing of the first sub-stream of the first SDF.

[0156] In some embodiments, the name of the first indication information is not limited, and it may be, for example, an accelerated transfer indication, an accelerated processing indication, a QoS improvement indication, etc.

[0157] In some embodiments, the fourth network element 1034 may directly or indirectly send the first instruction information to the first network element 1031.

[0158] In some embodiments, the fourth network element 1034 may be an AF (Automatic Field Array), and the first network element 1031 may be a PCF (Programmable Array Function). In one example, the AF may directly send the first indication information to the PCF. In another example, the AF may send the first indication information to the NEF (Neural Array Function), and the NEF may send the first indication information to the PCF.

[0159] In some embodiments, the fourth network element 1034 may also send QoS requirements to the first network element 1031. In one example, the QoS requirements may be related to the first SDF or the first sub-flow. In some embodiments, the QoS requirements may include requirements related to the QoS characteristics of the first SDF or the first sub-flow for the first service, including transmission rate, latency, uplink / 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.

[0160] In some embodiments, the first indication information and / or QoS requirements can be used by the first network element 1031 to authorize and identify data acceleration processing.

[0161] In some embodiments, the fourth network element 1034 may also send at least one of the following to the first network element 1031: the identifier of the first service, the address and / or identifier of the terminal 101, the identifier of the first network element 1031, the application identifier of the first service, the flow description, the data network name (DNN), the single network slice selection assistance information (S-NSSAI), and the QoS parameters.

[0162] In step S202, the first network element 1031 performs a strategy decision.

[0163] In some embodiments, the first network element 1031 may perform policy decisions to determine rules related to data acceleration processing for the first SDF.

[0164] In some embodiments, the execution of the policy decision of the first network element 1031 may take into account the first indication information. In some embodiments, the policy decision of the first network element 1031 may be implemented based on at least the first indication information. In some embodiments, upon receiving the first indication information, the first network element 1031 may determine rules related to data acceleration processing for the first SDF, taking into account the first indication information.

[0165] In some embodiments, the rules related to data acceleration processing may include a first rule and a second rule. In some embodiments, data acceleration processing may be targeted at a first SDF. In one example, both the first rule and the second rule may be rules authorized by the first network element 1031 for the first SDF. In some embodiments, data acceleration processing may be targeted at a first sub-flow of the first SDF. In one example, both the first rule and the second rule may be rules authorized by the first network element 1031 for the first sub-flow.

[0166] In some embodiments, each of the first rule and the second rule determined by the first network element 1031 may be a PCC rule. It is understood that the first rule and the second rule may also be other rules, and this disclosure does not specifically limit them.

[0167] In some embodiments, the first rule may correspond to accelerated processing of a first SDF or a first sub-stream. In some embodiments, during the process of performing data acceleration processing on the first SDF, the QoS characteristics corresponding to the first rule may be applied to the first SDF or the first sub-stream.

[0168] In some embodiments, the second rule may correspond to the normal processing of the first SDF or the first sub-stream. In some embodiments, when no data acceleration processing is performed on the first SDF, the QoS characteristics corresponding to the second rule may be applied to the first SDF or the first sub-stream.

[0169] In some embodiments, the first rule and the second rule can be bound to different QoS flows. These different QoS flows can have different QoS characteristics. The QoS flow bound to the first rule can be used for data acceleration processing of the first SDF or the first sub-flow. The QoS flow bound to the second rule can be used for normal processing (or basic processing) of the first SDF or the first sub-flow.

[0170] In some embodiments, the QoS bound by the first rule may have a higher priority and / or higher QoS characteristics compared to the QoS flow bound by the second rule.

[0171] In some embodiments, the first rule and the second rule related to data acceleration processing can be associated. In other words, the first rule and the second rule can constitute a rule pair related to 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.

[0172] In step S203, the first network element 1031 sends the second information to the second network element 1032.

[0173] In some embodiments, the first network element 1031 may send second information. In some embodiments, the second information may be sent by the first network element 1031, but is not limited thereto, and may also be sent by other entities.

[0174] In some embodiments, the second network element 1032 may receive the second information. In some embodiments, the second information may be received by the second network element 1032, but is not limited thereto, and may also be received by other entities.

[0175] In some embodiments, the second information may be used to indicate the first rule and the second rule. In some embodiments, the first information may be used to indicate the first rule and the second rule determined by the PCF for the first SDF or the first subflow.

[0176] In some embodiments, the name of the second information is not limited, and it may be, for example, rule instruction information, rule notification information, etc.

[0177] In some embodiments, the second information may include at least one of the following: first indication information, first identification information, first description information, and second identification information.

[0178] In some embodiments, the first identification information may be used to identify the first sub-stream.

[0179] In some embodiments, the first description information may be used to describe the QoS requirements of the first sub-stream.

[0180] In some embodiments, the second identification information can be used to identify the association between the first rule and the second rule.

[0181] In some embodiments, data acceleration processing may be targeted at a first SDF, and the second information may include first indication information and / or second identification information.

[0182] In some embodiments, the data acceleration processing may be targeted at the first subpath, and the second information may include first indication information and / or second identification information, as well as first identification information and / or first description information.

[0183] In some embodiments, the second identification information may include at least one of the following: identification information of the first rule and identification information of the second rule, identification information of the association between the first rule and the second rule, and indication information of the group to which the first rule and the second rule belong.

[0184] In some embodiments, the second information may be included in the first rule and / or the second rule. In some embodiments, the first network element 1031 may send the first rule and the second rule to the second network element 1032. The first rule and / or the second rule may include the second information. It is understood that the second information may also be independent of the first rule and the second rule, and may be sent by the first network element 1031 alone, or sent together with the first rule and the second rule.

[0185] In step S204, the second network element 1032 determines the QoS-related rules.

[0186] In some embodiments, the second network element 1032 may perform QoS flow binding and determine QoS-related rules based at least on the second information. In some embodiments, the second network element 1032 may perform QoS flow binding and determine QoS-related rules while taking the second information into consideration.

[0187] In some embodiments, the implementation of QoS flow binding and the determination of QoS-related rules can also be based on the local configuration of the second network element 1032. In one example, the local configuration of the second network element 1032 may include at least one of the following: protocol agreement, operator policy.

[0188] In some embodiments, QoS flow binding may include binding rules to QoS flows. In some embodiments, binding rules to QoS flows may include: a first rule being bound to a first QoS flow and a second rule being bound to a second QoS flow. In some embodiments, binding rules to QoS flows may be implemented based on at least one of second information, a first rule, a second rule, and local configuration.

[0189] In some embodiments, QoS-related rules may include at least one of the following: QoS rules, QoS profiles, and N4 rules.

[0190] In some embodiments, QoS rules can be used by terminal 101 to implement QoS processing.

[0191] In some embodiments, QoS configuration can be used by access network device 102 to implement QoS processing.

[0192] In some embodiments, the N4 rule can be used by the third network element 1033 to implement QoS processing.

[0193] In some embodiments, the N4 rule may include a PDR.

[0194] In some embodiments, the second network element 1032 may determine QoS rules, and / or QoS configuration, and / or N4 rules for the first SDF. In some embodiments, the second network element 1032 may determine QoS rules, and / or QoS configuration, and / or N4 rules for the first sub-flow.

[0195] In some embodiments, step S204 may include: determining first information.

[0196] In some embodiments, the first information is used to perform QoS mapping on the first SDF or the first sub-stream.

[0197] Understandably, QoS mapping refers to carrying data from a data stream within a QoS stream. For example, QoS mapping for a first SDF could mean carrying the data from the first SDF within the corresponding QoS stream. Similarly, QoS mapping for a first sub-stream could mean carrying the data from the first sub-stream within the corresponding QoS stream. In one example, QoS mapping can be implemented by marking the headers of data packets in the data stream. For instance, a QFI can be marked in the data packets of the first SDF or the data packets of the first sub-stream to map the data packets to the QoS stream corresponding to that QFI.

[0198] In some embodiments, the first information may be a packet filter set. In some embodiments, the first information may be included in the packet filter set. The packet filter set may be included in QoS-related rules. In one example, the packet filter set may be included in at least one of a QoS rule and a PDR.

[0199] In some embodiments, a packet filter rule may include one or more packet filters. Each packet filter may be applied to the uplink, downlink, or both uplink and downlink directions.

[0211] In some embodiments, the second identification information can be used to identify the association between the first rule and the second rule.

[0212] In some embodiments, the second indication information can be used to trigger a reflection QoS mechanism on the first SDF or the first sub-flow mapped to the QoS flow bound to the first rule. In some embodiments, the second indication information can be used to instruct the addition of a reflection QoS indication (RQI) to packets in the first SDF or the first sub-flow that undergo data acceleration processing. In some embodiments, the second indication information can be used to instruct uplink data acceleration processing for the first SDF or the first sub-flow.

[0213] In some embodiments, the reflected QoS mechanism (or reflected QoS) enables the terminal 101 to map uplink user plane traffic to a QoS flow even when the second network element 1032 does not provide QoS rules. In some embodiments, in the reflected QoS mechanism, the terminal 101 can determine the QoS rules for uplink traffic based on the received downlink traffic. Then, the terminal 101 can use the determined QoS rules to determine the mapping of uplink traffic to a QoS flow. In one example, the third network element 1033 can set RQI in the header of the downlink data packet in the first SDF or the first subflow. Then, the terminal 101 can determine the QoS rule corresponding to the downlink data packet based on the RQI in the received downlink data packet and implement uplink QoS mapping.

[0214] In step S205, the second network element 1032 sends the first information to the third network element 1033.

[0224] In some embodiments, the fifth network element 1035 can send data packets. In some embodiments, the data packets can be sent by the fifth network element 1035, but are not limited to this; they can also be sent by other entities.

[0225] In some embodiments, the third network element 1033 can receive data packets. In some embodiments, the data packets can be received by the third network element 1033, but are not limited to this; they can also be sent by other entities.

[0226] In some embodiments, the data packets sent by the fifth network element 1035 to the third network element 1033 may include downlink data packets.

[0227] In some embodiments, the data packet may include data packets in the first SDF of the first service.

[0228] In some embodiments, a data packet may include a data packet in a first substream of a first SDF of a first service.

[0229] In some embodiments, data packets can be transmitted on the user plane via the N6 interface.

[0230] In some embodiments, the header of the data packet may carry first indication information.

[0231] In step S208, the third network element 1033 performs QoS mapping.

[0232] In some embodiments, the third network element 1033 can detect and map the downlink data packets received from the first SDF.

[0233] In some embodiments, the third network element 1033 can detect and identify the first indication information in the header of the downlink data packet of the first SDF.

[0234] In some embodiments, step S208 may include: the third network element 1033 performing data acceleration processing related to the first SDF or the first sub-flow. In some embodiments, the data acceleration processing may include: performing QoS enhancement on the first SDF, performing QoS fallback on the first SDF, performing QoS enhancement on the first sub-flow, and performing QoS fallback on the first sub-flow.

[0235] In some embodiments, the third network element 1033 can determine whether the data acceleration processing is applied to the first SDF or the first sub-stream based on the first information. In one example, the first information includes at least one of first identification information and first description information, in which case the data acceleration processing is applied to the first sub-stream. In another example, the first information does not include the first identification information and the first description information, in which case the data acceleration processing is applied to the first SDF.

[0236] In some embodiments, the direction of data acceleration processing of the first SDF may include uplink and / or downlink.

[0237] In some embodiments, if a first indication information is detected in the header of a downlink data packet of the first SDF, the third network element 1033 may determine to perform data acceleration processing on the first SDF. In some embodiments, if a first indication information is detected in the header of a downlink data packet of the first SDF, the third network element 1033 may determine to perform data acceleration processing on the downlink data packet of the first SDF.

[0238] In some embodiments, if a first indication information is detected in the header of a downlink data packet of a first sub-stream, the third network element 1033 may determine to perform data acceleration processing on the first sub-stream. In some embodiments, if a first indication information is detected in the header of a downlink data packet of a first sub-stream, the third network element 1033 may determine to perform data acceleration processing on the downlink data packet of the first sub-stream.

[0239] In some embodiments, the first substream may be unencrypted.

[0240] In some embodiments, the first sub-stream may be encrypted. In this case, the third network element 1033 can detect the downlink data packets of the first sub-stream based on the first identification information and / or the first description information in the first information. In one example, the header of the downlink data packets of the first sub-stream may carry the first identification information and / or the first description information, then the third network element 1033 can detect the downlink data packets of the first sub-stream based on the first identification information and / or the first description information in the first information.

[0241] In some embodiments, to accelerate data 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 packets of the first SDF or the first sub-flow from the second QoS flow to the first QoS flow. In one example, the third network element 1033 can switch the QFI corresponding to the data packets of the first SDF or the first sub-flow from the second QFI to the first QFI.

[0242] In some embodiments, the first QFI corresponds to the first QoS stream. The first QFI may indicate the QoS characteristics of the first QoS stream.

[0243] In some embodiments, the second QFI corresponds to the second QoS stream. The second QFI may indicate the QoS characteristics of the second QoS stream.

[0244] 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. In some embodiments, the first QoS may have a higher priority and / or better QoS characteristics than the second QoS flow.

[0245] In some embodiments, the third network element 1033 can determine the association between the first QoS flow and the second QoS flow based on the second identification information. Therefore, if it is determined that downlink data acceleration processing should be performed on the first SDF or the first sub-flow, the third network element 1033 can determine that the first SDF or the first sub-flow switches from the second QoS flow to the first QoS flow.

[0246] In some embodiments, when it is determined that uplink data acceleration processing is to be performed on the first SDF or the first sub-stream, the third network element 1033 may mark RQI in the downlink data packets of the first SDF or the first sub-stream. At this time, the first SDF or the first sub-stream is mapped to the first QoS stream. In some embodiments, when it is determined that uplink data acceleration processing is to be performed on the first SDF or the first sub-stream based on second indication information, the third network element 1033 may mark RQI in the downlink data packets of the first SDF or the first sub-stream. In one example, upon receiving the second indication information, the third network element 1033 may mark RQI in the downlink data packets of the first SDF or the first sub-stream mapped to the first QoS stream.

[0247] In some embodiments, the third network element 1033 may determine that data acceleration processing will no longer be performed on the first SDF or the first sub-stream. In one example, data acceleration processing on the first SDF or the first sub-stream may terminate. In some embodiments, the header of the downlink data packet of the first SDF or the first sub-stream may no longer carry the first indication information, in which case the third network element 1033 may determine that data acceleration processing will no longer be performed on the first SDF or the first sub-stream. In some embodiments, the timer for data acceleration processing times out, in which case the third network element 1033 may determine that data acceleration processing will no longer be performed on the first SDF or the first sub-stream.

[0248] In some embodiments, after the data acceleration processing is completed, 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 packets of the first SDF or the first sub-flow from the first QoS flow to the second QoS flow. In one example, the third network element 1033 can switch the QFI corresponding to the data packets of the first SDF or the first sub-flow from the first QFI to the second QFI.

[0249] In some embodiments, the third network element 1033 can determine the association between the first QoS flow and the second QoS flow based on the second identification information. Then, upon determining that the downlink data acceleration processing for the first SDF or the first sub-flow has ended, the third network element 1033 can determine that the first SDF or the first sub-flow switches from the first QoS flow to the second QoS flow.

[0250] In some embodiments, the first indication information can be used to implement QoS optimization processing for a first sub-flow. In some embodiments, the first indication information can be used to indicate that the first sub-flow has higher QoS requirements. In some embodiments, the QoS optimization processing for the first sub-flow may include QoS classification matching for the first sub-flow. In some embodiments, when the first SDF includes multiple sub-flows, multiple sets of QoS features (corresponding to multiple QoS flows) can be used to implement classification processing for multiple sub-flows. Different sub-flows may differ in QoS requirements, QoS parameters, flow characteristics, service characteristics, etc. Therefore, different sub-flows can be matched with different QoS features or QoS flows. In this case, the first indication information can be used to implement QoS matching for the first sub-flow. QoS matching can refer to the matching between QoS requirements and QoS features or QoS flows. For example, the first indication information can be used to match the first sub-flow with higher QoS features. This means mapping the first sub-flow to a QoS flow with higher priority and / or higher QoS features.

[0251] In step S209, the third network element 1033 sends a data packet to the terminal 101.

[0252] In some embodiments, the third network element 1033 can send data packets. In some embodiments, the data packets can be sent by the third network element 1033, but are not limited to this; they can also be sent by other entities.

[0253] In some embodiments, terminal 101 may receive data packets. In some embodiments, data packets may be received by terminal 101, but are not limited thereto, and may also be sent by other entities.

[0254] In some embodiments, when the first SDF or the first sub-stream uses downlink data acceleration processing, the third network element 1033 can map data packets to the first QoS stream and send them.

[0255] In some embodiments, when the first SDF or the first sub-stream uses uplink data acceleration processing, the third network element 1033 can mark RQI in the data packet and send it through the first QoS stream.

[0256] In some embodiments, when the data acceleration processing of the first SDF or the first sub-stream ends, the third network element 1033 can map the data packet to the second QoS stream and send it.

[0257] In some embodiments, the third network element 1033 may send data packets to the terminal 101 via the access network device 102.

[0258] In step S210, terminal 101 sends a data packet to the fifth network element 1035.

[0259] In some embodiments, terminal 101 may send data packets. In some embodiments, data packets may be sent by terminal 101, but are not limited to this, and may also be sent by other entities.

[0260] In some embodiments, the fifth network element 1035 can receive data packets. In some embodiments, the data packets can be received by the fifth network element 1035, but are not limited thereto; they can also be received by other entities.

[0261] In some embodiments, terminal 101 can send data packets to fifth network element 1035 via third network element 1033.

[0262] In some embodiments, terminal 101 may perform data acceleration processing related to a first SDF or a first substream.

[0263] In some embodiments, data acceleration processing may include: performing QoS enhancement on a first SDF, performing QoS fallback on the first SDF, performing QoS enhancement on a first sub-stream, and performing QoS fallback on the first sub-stream.

[0264] 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 the first identification information and the first description information, then the data acceleration processing is applied to the first SDF.

[0265] In some embodiments, the direction of the first SDF's data acceleration processing is uplink.

[0266] 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.

[0267] 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. In some embodiments, the first QoS may have a higher priority and / or better QoS characteristics than the second QoS flow.

[0268] 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 should 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.

[0269] 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.

[0270] 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.

[0271] 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 the downlink data acceleration processing for the first SDF or the first sub-stream has ended, terminal 101 can determine that the first SDF or the first sub-stream switches from the first QoS stream to the second QoS stream.

[0272] In some embodiments, the data packets sent by terminal 101 may include uplink data packets of the first SDF or the first substream.

[0273] In some embodiments, the header of the downlink data packet received by terminal 101 from third network element 1033 may carry RQI. In this case, terminal 101 may use the QoS characteristics corresponding to the QoS characteristics of the downlink data packet to send the uplink data packet.

[0274] In some embodiments, the downlink data packets of the first SDF or the first sub-stream received by terminal 101 may be in the first QoS stream, and the header of the downlink data packets carries RQI. In this case, terminal 101 can map the uplink data packets of the first SDF or the first sub-stream to the first QoS stream. It is understood that the first QoS stream to which the uplink data packets are mapped and the first QoS stream to which the downlink data packets are mapped may be the same QoS stream, or they may be two QoS streams with the same or related QoS characteristics.

[0275] In some embodiments, multiple data acceleration processes can be performed on the first SDF. In some embodiments, during the implementation process of the first service, the first SDF can undergo multiple QoS upgrades (i.e., switching to the first QoS stream) and multiple QoS fallbacks (i.e., switching back to the second QoS stream). In some embodiments, after one data acceleration process on the first SDF is completed, the first SDF can be subjected to data acceleration processing again.

[0276] In some embodiments, after the data acceleration processing of the first SDF is completed through steps S201 to S210, the third network element 1033 can switch the first SDF from the first QoS stream to the second QoS stream. Afterward, the third network element 1033 can detect whether subsequently received downlink data packets of the first SDF carry 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 is completed and the first SDF is switched to the second QoS stream, the third network element 1033 can detect the first indication information in subsequent downlink data packets of the first SDF. At this time, the third network element 1033 can perform data acceleration processing on the first SDF again. The first SDF can switch from the second QoS stream to the first QoS stream. The process of the third network element 1033 performing data acceleration processing on the first SDF again can be found in the description of steps S201 to S210 above, and will not be repeated here.

[0314] In the following, specific embodiments of the present disclosure will be described by way of example.

[0315] In some embodiments, this disclosure employs enhanced packet filter settings (i.e., first information) to support accelerated data processing. The enhanced packet filter settings include an accelerated transfer indication.

[0316] In some embodiments, enhanced packet filters with accelerated transfer indications can be used in QoS rules (implementing uplink flow detection and QoS flow mapping for the UE) and PDRs (implementing downlink flow detection and QoS flow mapping for the UPF) to identify one or more packet flows.

[0317] In some embodiments, during data acceleration processing, QoS enhancement for uplink non-GBR streams can be achieved through reflection QoS.

[0318] In some embodiments, for data acceleration functionality of one or more sub-streams in a composite data stream, sub-stream identifiers or media stream description information can be added while including an acceleration transfer indication in the enhanced packet filter settings. In some embodiments, sub-stream data acceleration processing can support both encrypted and unencrypted scenarios.

[0319] In some embodiments, for IP PDU session types, packet filter settings support packet filtering based on at least one of the following: source / destination IP address or IPv6 prefix; source / destination port number; protocol identifier of the protocol for the IP / next header type; type of service (ToS) (IPv4) / traffic level (IPv6) and mask; flow label (IPv6); security parameter index; packet filter direction; accelerated transfer indication (i.e., first indication information); sub-flow identifier (i.e., first identification information) or media stream description information (i.e., first description information).

[0320] In some embodiments, an accelerated transfer indication can indicate data acceleration and higher QoS requirements. Then, if an accelerated transfer indication is detected, a higher QoS flow can be applied, bound to a PCC rule with higher QoS authorization; if an accelerated transfer indication is not detected, a lower QoS flow can be applied, bound to a PCC rule with lower QoS authorization.

[0321] In some embodiments, substream identifiers or media stream description information may indicate composite data streams with multiple QoS requirements and / or multiple QoS authorizations.

[0322] In some embodiments, substream identifiers or media stream description information may be included in packet filter settings along with acceleration transfer indications to support accelerated data traffic for one or more substreams in a composite data stream.

[0323] In some embodiments, the substream identifier may be a track identifier in the MoQ protocol, a stream identifier in the QUIC protocol, etc.

[0324] In some embodiments, media stream description information may be a protocol type or a feature field within the protocol type, such as RTP SSRC or RTP payload type, to indicate different QoS requirements.

[0325] Figure 4 is an interactive schematic diagram of an exemplary implementation of the communication method provided according to embodiments of the present disclosure. In some embodiments, the communication method may involve the AS requesting a 5GS QoS upgrade by using a reflection QoS feature, or the AS supporting the communication system to perform QoS-specific optimization processing, such as QoS classification matching processing, by using multiple sets of QoS features.

[0326] As shown in Figure 4, the communication method includes steps S401 to S406.

[0327] In step S401, the PDU session establishment process and the AF session request process under the QoS requirements of SDF are executed.

[0328] In some embodiments, the AF (i.e., the fourth network element) (directly or through the NEF) provides the PCF (i.e., the first network element) with an acceleration transfer indication (i.e., first indication information) and QoS requirements to assist in the authorization and identification of data acceleration (e.g., determining two PCC rules for data acceleration of SDF, or data acceleration of sub-streams of composite SDF). The IP packet filter may have an acceleration transfer indication and may include sub-stream identifiers or media stream description information, and may also include associated identifiers of PCC rules (i.e., second identifier information), and use this information to help the UPF identify downlink PDUs and map them to the corresponding QoS streams.

[0329] In some embodiments, the PCF may include an acceleration transfer indication in one or two authorized PCC rules (i.e., the first rule and / or the second rule) for the SMF (i.e., the second network element) to request the identification and switching of traffic that has enabled data acceleration.

[0330] In some embodiments, PCC rules can be enhanced to support accelerated transfer indications, substream identifiers or media stream description information, and associated identifiers of PCC rules. This information can be used to help the UPF identify downlink PDUs and map them to the corresponding QoS streams, and can be sent by the PCF to the SMF.

[0331] In some embodiments, based on the acceleration transfer indication in the PCC rules and / or local configuration, the SMF performs the binding of two PCC rules with two QoS flows and generates QoS rules, QoS configuration, and N4 rules. The acceleration transfer indication, (optionally) support for sub-stream identifiers or media stream description information, and (optionally) the associated identifier of the PCC rules can be provided in the QoS rules and / or N4 rules for use in SDF detection during data acceleration or sub-stream detection of composite SDF during data acceleration.

[0332] In some embodiments, taking into account accelerated transfer indication, (optionally) support for substream identifiers or media stream description information, and (optionally) associated identifiers of PCC rules, the SMF instructs the UPF to identify and enable data acceleration, for example, by performing QoS stream mapping for the downlink direction.

[0333] In some embodiments, for traffic that triggers and identifies data acceleration, a second non-GBR 5QI is configured with a higher priority value and better QoS compared to a normal 5QI with a first PCC rule that has no data acceleration authorization.

[0334] In some embodiments, according to the instructions of the SMF, for the downlink direction, an IP packet filter setting having an acceleration transfer indication, (optionally) support for sub-stream identifiers or media stream description information, and (optionally) associated identifiers of PCC rules can be used by the UPF (i.e., the third network element) for the detection of sub-streams of SDF or composite SDF during data acceleration and mapped to QoS streams.

[0335] In step S402 (including steps S402a and S402b), after PCC and QoS authorization and the binding of PCC rules with QoS flows, the UE (i.e., the terminal) sends uplink data to the AS (i.e., the fifth network element) or receives downlink data from the AS. The UE can use an authenticated QoS flow or a default QoS flow.

[0336] In step S403 (including steps S403a and S403b), based on application requirements in the AS, the AS instructs the UE to send data files with higher resolution (e.g., videos, pictures). Because the AS detects that the amount of data from the UE will increase, and the timely receipt of this information is crucial for the application, the AS can include this request in the metadata to accelerate the data transfer to 5GS.

[0337] In some embodiments, the AS may provide an accelerated transfer instruction to the UPF. This accelerated transfer instruction is carried in the N6 PDU header of the downlink SDF.

[0338] In step S404, for the downlink direction, IP packet filter settings with acceleration transfer indication, (optionally) support for sub-stream identifier or media stream description information, and (optionally) associated identifier of PCC rules are used by UPF for the detection and mapping of sub-streams of SDF or composite SDF during data acceleration to QoS streams.

[0339] In some embodiments, considering enhanced IP packet filter settings, the UPF switches the SDF from the first QFI to a second QFI with a higher priority value and higher licensed QoS, and applies reflection QoS. For example, the UPF switches the SDF from the first QFI to the second QFI with a higher priority value and higher licensed QoS to apply RQI marking to the downlink PDUs of the SDF.

[0340] In some embodiments, taking into account enhanced IP packet filter settings, the UPF switches the SDF from a higher QFI to a basic QFI after the data acceleration process has ended.

[0341] In some embodiments, the UPF can perform subsequent uplink and / or downlink transfers by selecting a QoS flow with a higher quality 5QI (e.g., 5QI-6) established in step S401.

[0342] In steps S405 and S406 (including steps S406a and S406b), for the uplink direction, IP packet filter settings with acceleration transfer indication, (optionally) support for sub-stream identifier or media stream description information, and (optionally) associated identifier of PCC rules are used by the UE for the detection of SDF or composite SDF during data acceleration and mapped to QoS stream.

[0343] In some embodiments, upon receiving a downlink data packet with RQI, the UE transfers the associated uplink SDF from the default QoS stream to a QoS stream using a second QFI with RQI.

[0344] In some embodiments, if the timer for reflected QoS times out and / or the RQI is not marked in the downlink packet, the UE can transfer the associated uplink SDF from the QoS stream with a higher QFI back to the default QoS stream.

[0345] In some embodiments, IP packet filter settings having an accelerated transfer indication, (optionally) support for sub-stream identifiers or media stream description information, and (optionally) association identifiers for PCC rules can be provided to the UPF via the PCF and SMF. In some embodiments, IP packet filter settings having an accelerated transfer indication, (optionally) support for sub-stream identifiers or media stream description information, and (optionally) association identifiers for PCC rules can be provided to the UE via the PCF, SMF, AMF, and NG-RAN.
