[0232] In some cases, services such as mobile media services, online AR / VR and other XR services, online gaming, and video-based remote control of machines or drones are expected to contribute increasingly high traffic volumes to communication networks. XR services involve multimodal data streams. Multimodal data is data describing the same service / application that is input from the same device or different devices (including sensors) and may be output to one or more destination devices. The data streams within multimodal data often have some, or even strong, correlation, such as synchronization between audio and video streams, or between touch and vision. These media services share common characteristics within their data streams, between the data streams themselves, and in terms of the network transmission requirements. Effectively identifying and leveraging these characteristics will facilitate network and service transmission and control, as well as enhance service assurance and user experience.

[0233] In further cases, XRM services and interactive media services require the communication system to comprehensively consider the QoS characteristics of service data flows. Such QoS characteristics may include, for example, at least one of the following: whether parameters such as delay-sensitive guaranteed bit rate (GBR) data flows, guaranteed flow bit rate (GFBR), packet delay budget (PDB), and default maximum data burst volume (MDBV) can be simultaneously met and coordinated. It involves multiple XRM data flows of a terminal, and XRM data flows of multiple terminals, and the consistency of QoS authorization and execution between each other.

[0234] In some embodiments, the SDF of the XRM may support PDU set-based processing, thereby enhancing QoS awareness and assurance of the SDF and improving the user's quality of experience (QoE).

[0235] In some embodiments, in systems such as 4G, 5G, 6G, and V2X, the AF may 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). The SMF and UPF may then extend the header of the PDU in the SDF's PDU set in combination with the protocol description and protocol header extension provided by the AF to carry the PDU set information.

[0237] It can be understood that the UPF performs the mapping of the SDF to the QoS flow based on the PDR, and maps (also referred to as encapsulating) the mutually related PDUs into the PDU set. In addition, the UPF can adopt the same QoS policy for 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 one 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 (for example, intra-frame coded frames and predicted frames), and the UPF classifies these PDUs as belonging to the PDU set and performs corresponding control.

[0238] In some embodiments, in order to enhance the control and management of data flows of XRM services, QoS parameters may be measured, monitored, and reported.

[0641] In the following, the technical solutions of the embodiments of the present disclosure are exemplarily described through specific implementation methods.

[0642] In some embodiments, QoS monitoring / measurement of PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) (i.e., first parameters) can be applied based on AF request and / or PCF policy control. The RAN / UPF is required to provide QoS monitoring results of the measurements of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate).

[0643] In some embodiments, the AF (i.e., the second network element) may request to reserve resources for the AF session via the Nnef_AFsessionWithQoS_Create request message. During the AF QoS request / update process, the AF may provide the NEF / PCF with QoS monitoring requirements including PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate).

[0644] In some embodiments, the first CP NF (ie, the first network element) may be, for example, a PCF.

[0645] In some embodiments, the PCF generates an authorized QoS monitoring policy (i.e., first policy information) for PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) for the service data flow based on the QoS monitoring request received from the AF.

[0646] In some embodiments, the PCF includes the authorized QoS monitoring policy for PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) in the PCC rules and provides it to the SMF.

[0647] In some embodiments, the second CP NF (ie, the third network element) may be, for example, an SMF.

[0648] In some embodiments, when the SMF receives an authorized QoS monitoring policy for PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate), the SMF configures the UPF and / or NG-RAN to measure the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate).

[0649] In some embodiments, for a QoS flow whose parameters are determined by the SMF based on the authorized QoS monitoring policy and / or local configuration received from the PCF, the SMF configures the UPF to report the QoS monitoring results (i.e., measurement results) of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate).

[0650] In some embodiments, after receiving the report from the UPF, the SMF forwards the report on the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) to the PCF to determine the PCC rules; and exposes it to the AF if the AF subscribes. In some embodiments, the UPF reports the measurement results of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) to the AS / AF (directly or through the NEF) as instructed.

[0651] In some embodiments, the first UP NF may be, for example, a UPF.

[0652] In some embodiments, the SMF configures the UPF to perform QoS monitoring of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) of the QoS flow and report the monitoring results:

[0653] - QoS parameters to be measured, used to indicate the subject of the QoS monitoring PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate);

[0654] -Reporting period, used to indicate the time interval for new measurement results and possible reporting;

[0655] -Report frequency, used to indicate whether the reporting type is "periodic" or "event-triggered";

[0656] - (Optional) Reporting target and direct event notification indication, used to indicate that the UPF should report to a different network function other than the SMF (e.g., local NEF or AF).

[0657] In some embodiments, the UPF performs QoS monitoring on PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate).

[0658] In some embodiments, the UPF reports the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) to the SMF and reaches the PCF, and / or reports to the local NEF, and / or reports to the AS / AF (directly or through the NEF).

[0659] In some embodiments, the consumer may be, for example, the RAN. In some embodiments, the consumer may refer to the object to which the service is provided. For example, in a service-based scenario, the service may be provided to the consumer. In some embodiments, the monitoring and / or reporting information and / or parameters for the first parameter provided by the AF and / or PCF may be provided to the RAN. In this case, the RAN may be considered the consumer. It is understood that the consumer may be independent of the device. The object of the service provision is the consumer.

[0660] In some embodiments, the RAN and / or UPF may perform monitoring, measurement, and reporting of PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate).

[0661] In some embodiments, the measurement method of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) can be performed by referring to the definition description of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate); for example, the delay of the PDU set includes not only the transmission delay between the UE and the RAN and / or the RAN and the UPF, but also the delay between the first data packet and the last data packet received in the PDU set; for example, whether the PDU set bit error rate / packet loss rate includes the packet loss rate of the RAN performing active packet loss per PDU set (Per Set) and whether it includes the packet loss rate of the active packet loss per PDU set identifier (Per PSI) can be based on the RAN implementation or operator policy or the definition description of the PDU set bit error rate / packet loss rate.

[0662] In some embodiments, the PDU set QoS parameter (e.g., PDU set delay, PDU set bit error rate / packet loss rate) measurement results are reported in the following ways: reporting to the PCF (through the SMF) via the CP (control plane) for the PCF to make PCC decisions, such as updating PCC rules or generating new PCC rules; or sending to the AS / AF (directly or through the NEF) via the UP (user plane) for the AS / AF to update QoS requirements or make AF session requests (e.g., update PDU set parameters).

[0663] In some embodiments, monitoring is performed and subscription reporting is performed on the following two types of PDU set parameters: PDU set bit error rate / packet loss rate, and PDU set delay.

[0664] In some embodiments, for the PDU set bit error rate / packet loss rate, the NG-RAN provides a measurement value of the PDU set bit error rate / packet loss rate.

[0665] In some embodiments, the reporting period, the frequency of periodic reporting, and the frequency of event-triggered reporting are applied to the monitoring and exposure of the bit error rate / packet loss rate of a PDU set.

[0666] In some embodiments, for event-triggered reporting, the RAN reports the measurement results when the measurement result meets a threshold (e.g., reaches the upper limit of the PDU set bit error rate / packet loss rate, or falls below the upper limit again, or reaches the upper limit of the PDU set bit error rate / packet loss rate for a period of time, or falls below the upper limit of the PDU set bit error rate / packet loss rate for a period of time). For event-triggered reporting, the maximum and minimum PDU set bit error rates / packet loss rates may also be reported.

[0667] In some embodiments, reporting may be directed by a local configuration of the SMF or UPF. In some embodiments, monitoring and reporting instructions may be directed by AF subscriptions, PCC rules from the PCF, or configuration from the SMF. If a reporting instruction is received, it may be used to replace the pre-configured value in the UPF.

[0668] In some embodiments, the NG-RAN and / or UPF provide PDU set bit error rate / packet loss rate measurements. The UPF reports the PDU set bit error rate / packet loss rate (measured by the UPF, or measured by the RAN, or calculated based on the UPF and RAN) to the AF via the NEF, or to the PCF via the SMF.

[0669] In some embodiments, when the RAN measures the PDU set packet loss rate, the RAN counts the discarded RAN sets. When the RAN measures the PDU set bit error rate, whether to count some or all of the discarded PDU sets into the PSER may be determined by operator policy.

[0670] In some embodiments, the NG-RAN and UPF may provide measurements of PDU set delay.

[0671] In some embodiments, the PCF triggers the QoS monitoring process, instructing one or more of the following PDU set delays to be monitored and reported to the SMF: UL PDU set delay, DL PDU set delay, UL RAN-PDU set delay, UL CN-PDU set delay, DL RAN-PDU set delay, DL CN-PDU set delay.

[0672] In some embodiments, the UPF obtains the indicated PDU set delay based on measurements of the UPF and / or the RAN.

[0673] In some embodiments, the UPF obtains the UL PDU set delay based on the UL RAN-PDU set delay and the UL CN-PDU set delay.

[0674] In some embodiments, the UPF obtains the DL PDU set delay based on the DL RAN-PDU set delay and the DL CN-PDU set delay.

[0675] In some embodiments, the UPF obtains the RT (round-trip) PDU set delay based on the RT RAN-PDU set delay and the RT CN-PDU set delay.

[0676] In some embodiments, the UPF reports the measured value of the PDU set delay to the AS / AF (directly or through the NEF).

[0677] In some embodiments, the reporting period, periodic reporting frequency, and event-triggered reporting frequency may be applied to the monitoring of PDU set delay.

[0678] In some embodiments, for event-triggered reporting, when the measurement result matches a threshold (eg, reaches an upper limit of the PDU set delay, or falls below a lower limit of the PDU set delay), the RAN reports the measurement result.

[0679] In some embodiments, for event-triggered reporting, a minimum PDU set delay report and a maximum PDU set delay report may also be reported to the PCF.

[0680] In some embodiments, reporting can be indicated by local configuration of the SMF or UPF. In some embodiments, reporting can be indicated by an AF subscription, by a PCC rule of the PCF, or by a configuration from the SMF. If an indication is received, it is used to replace the pre-configured value in the UPF.

[0681] Figure 9A is an interactive diagram of an exemplary implementation of a communication method according to an embodiment of the present disclosure. The method can be implemented through the following process.

[0682] In step 1, the AF sends an AF session resource creation or update request, such as an Nnef_AFsessionWithQoS_Create request, to create an AF session. In one example, the AF includes in the request the QoS requirements for the XRM service and interactive media service data flows. In another example, the AF sends a QoS monitoring subscription request to subscribe to monitoring results for the corresponding PDU set QoS parameters. Optionally, the request includes a priority reporting method, such as CP reporting or UP reporting.

[0683] In some embodiments, QoS monitoring / measurement for PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate) can be applied based on AF request and / or PCF policy control.

[0684] During the AF QoS request / update process, the AF may provide the QoS monitoring requirements including PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate) to the NEF / PCF.

[0685] In some embodiments, the XRM service information may be carried to identify the XRM service data flow or data flow group (e.g., multimodal service ID), UE address / UE identifier, AF identifier, application ID, flow description, DNN, S-NSSAI, QoS parameters, and other corresponding information. Here, the multimodal service ID can be used to identify all flows in the XRM service group.

[0686] In step 2, the NEF authorizes the AF request. If it is an untrusted AF, the AF request is sent to the PCF through the NEF. (Optionally, the NEF performs relevant mappings, including mapping the XRM service (AF service identifier) ​​to the DNN and S-NSSAI, mapping the external application to the core network application identifier; and mapping the external UE identifier to the UE identifier within the core network based on the UDM subscription information (such as SUPI), and performing external to internal XRM service group identifier mapping based on the UDM subscription information).

[0687] In step 3, the NEF authorizes the AF request and determines whether to trigger the TSCTSF or contact the PCF directly based on the parameters provided by the AF. These signaling steps can be found in the AF session with required QoS process. The PCF receives the attributes provided by the AF from the NEF or TSCTSF. The NEF triggers Npcf_PolicyAuthorization_Create and sends the AF request to the PCF, carrying QoS requirement information for the PCF to make policy decisions. Npcf_PolicyAuthorization_Create carries the QoS monitoring requirements of the corresponding SDF for the PDU set QoS parameters (for example, PDU set delay, PDU set bit error rate / packet loss rate).

[0688] In step 4, the PCF makes a policy decision. The PCF may determine that updated or new policy information needs to be sent to the SMF.

[0689] In some embodiments, the PCF generates an authorized QoS monitoring policy for PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate) for the service data flow based on the QoS monitoring request received from the AF.

[0690] In some embodiments, the PCF includes the authorized QoS monitoring policy for PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) in the PCC rules and sends it to the SMF.

[0691] In step 5, in response, the PCF sends an Npcf_Policy Authorization_Create response to the NEF.

[0692] In step 6, the NEF sends an Nnef_AFsessionWithQoS_Create response message to the AF, which carries the result to inform whether the request is authorized.

[0693] In step 7, the PCF initiates an SM policy association modification request (PCC rule) to the SMF.

[0694] After receiving the PCC rules, the SMF determines the QoS rules and QoS set parameters to configure / activate the rules to the UPF (e.g., via N4 session). The QoS monitoring policy takes into account the QoS monitoring information of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate).

[0695] In some embodiments, when the SMF receives an authorized QoS monitoring policy for PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate), the SMF configures the UPF and / or NG-RAN to measure the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate).

[0696] In some embodiments, for QoS flows whose parameters are determined by the SMF based on the authorized QoS monitoring policy and / or local configuration received from the PCF, the SMF configures the UPF to report QoS monitoring results of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate).

[0697] In some embodiments, after receiving the report from the UPF, the SMF forwards the report on the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) to the PCF to determine the PCC rules; and exposes it to the AF if the AF subscribes. In some embodiments, the UPF reports the measurement results of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) to the AS / AF (directly or through the NEF) as instructed.

[0698] In step 8, in reply, the SMF sends an SM policy association modification response to the PCF.

[0699] In step 9, the SMF initiates a PDU session modification request to the UPF (QoS monitoring policy for PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate)).

[0700] In step 10, the UPF responds to the SMF.

[0701] In some embodiments, the NG-RAN provides measurements of the bit error rate / packet loss rate of a PDU set.

[0702] In some embodiments, the reporting period, the frequency of periodic reporting, and the frequency of event-triggered reporting are applied to the monitoring and exposure of the bit error rate / packet loss rate of a PDU set.

[0703] In some embodiments, for event-triggered reporting, the RAN reports the measurement results when the measurement result meets a threshold (e.g., reaches the upper limit of the PDU set bit error rate / packet loss rate, or falls below the upper limit again, or reaches the upper limit of the PDU set bit error rate / packet loss rate for a period of time, or falls below the upper limit of the PDU set bit error rate / packet loss rate for a period of time). For event-triggered reporting, the maximum and minimum PDU set bit error rates / packet loss rates may also be reported.

[0704] In some embodiments, reporting may be directed by a local configuration of the SMF or UPF. In some embodiments, monitoring and reporting instructions may be directed by AF subscriptions, PCC rules from the PCF, or configuration from the SMF. If a reporting instruction is received, it may be used to replace the pre-configured value in the UPF.

[0705] In some embodiments, the NG-RAN and / or UPF provide PDU set bit error rate / packet loss rate measurements. The UPF reports the PDU set bit error rate / packet loss rate (measured by the UPF, or measured by the RAN, or calculated based on the UPF and RAN) to the AS via the NEF, or to the PCF via the SMF.

[0706] In some embodiments, when the RAN measures the PDU set packet loss rate, the RAN counts the discarded RAN sets. When the RAN measures the PDU set bit error rate, whether to count some or all of the discarded PDU sets into the PSER may be determined by operator policy.

[0707] In some embodiments, the NG-RAN and UPF may provide measurements of PDU set delay.

[0708] In some embodiments, the PCF triggers the QoS monitoring process, instructing one or more of the following PDU set delays to be monitored and reported to the SMF: UL PDU set delay, DL PDU set delay, UL RAN-PDU set delay, UL CN-PDU set delay, DL RAN-PDU set delay, DL CN-PDU set delay.

[0709] In some embodiments, the UPF obtains the indicated PDU set delay based on measurements of the UPF and / or the RAN.

[0710] In some embodiments, the UPF obtains the UL PDU set delay based on the UL RAN-PDU set delay and the UL CN-PDU set delay.

[0711] In some embodiments, the UPF obtains the DL PDU set delay based on the DL RAN-PDU set delay and the DL CN-PDU set delay.

[0712] In some embodiments, the UPF obtains the RT PDU set delay based on the RT RAN-PDU set delay and the RT CN-PDU set delay.

[0713] In some embodiments, the UPF reports the measured value of the PDU set delay to the AS / AF (directly or through the NEF).

[0714] In some embodiments, the reporting period, periodic reporting frequency, and event-triggered reporting frequency may be applied to the monitoring of PDU set delay.

[0715] In some embodiments, for event-triggered reporting, when the measurement result matches a threshold (eg, reaches an upper limit of the PDU set delay, or falls below a lower limit of the PDU set delay), the RAN reports the measurement result.

[0716] In some embodiments, for event-triggered reporting, a minimum PDU set delay report and a maximum PDU set delay report may also be reported to the PCF.

[0717] In some embodiments, reporting can be indicated by local configuration of the SMF or UPF. In some embodiments, reporting can be indicated by an AF subscription, by a PCC rule of the PCF, or by a configuration from the SMF. If an indication is received, it is used to replace the pre-configured value in the UPF.

[0718] In some embodiments, the RAN and / or UPF may perform monitoring, measurement, and reporting of PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate). In some embodiments, the measurement results of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) are reported via the CP to the PCF (via the SMF) for the PCF to make PCC decisions, such as updating PCC rules or generating new PCC rules; or sent via the UP to the AS / AF (directly or via the NEF) for the AS / AF to update QoS requirements or make AF session requests (e.g., update PDU set parameters).

[0719] In step 11, for the modification requested by the SMF, the SMF causes Namf_Communication_N1N2MessageTransfer(N2 SM information (PDU session ID, QFI, QoS configuration, N1 SM container)).

[0720] In step 12, the AMF (ie, the sixth network element) may send an N2 message (N2 SM information received from the SMF, NAS message (PDU session ID, N1 SM container (PDU session modification command))) to the RAN.

[0721] In step 14, the RAN may acknowledge the N2 PDU Session Request by sending an N2 PDU Session Ack message to the AMF.

[0722] In step 15, the AMF forwards the N2 SM information from the access network to the SMF through the Nsmf_PDUSession_UpdateSMContext service operation.

[0723] In step 16, the SMF replies with an Nsmf_PDUSession_UpdateSMContext response.

[0724] In steps 17 and 18, SMF can update the N4 session of UPF involved in the PDU session modification by sending an N4 Session Modification request to UPF.

[0725] In some embodiments, the SMF configures the UPF to perform QoS monitoring of the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) of the QoS flow and report the monitoring results:

[0726] - QoS parameters to be measured, used to indicate the subject of the QoS monitoring PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate);

[0727] -Reporting period, used to indicate the time interval for new measurement results and possible reporting;

[0728] -Report frequency, used to indicate whether the reporting type is "periodic" or "event-triggered";

[0729] - (Optional) Reporting target and direct event notification indication, used to indicate that the UPF should report to a different network function other than the SMF (e.g., local NEF or AF).

[0730] In some embodiments, the UPF performs QoS monitoring on PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate).

[0731] In some embodiments, the UPF reports the PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) to the SMF and reaches the PCF, and / or reports to the local NEF, and / or reports to the AS / AF (directly or through the NEF).

[0732] Figure 9B is an interactive diagram of an exemplary implementation of a communication method according to an embodiment of the present disclosure. The method can be implemented through the following process.

[0733] In step 1a, a PDU session establishment process is performed.

[0734] In step 1b, the AF can send information (QoS parameters for each PDU set in the QoS flow and frame identification parameters) to the PCF through the Nnef_AFsessionWithQoS_Create request. Before the PDU session is established, the AF can also provide this information to the 5GS.

[0735] In some embodiments, QoS monitoring / measurement for PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate) can be applied based on AF request and / or PCF policy control.

[0736] In some embodiments, during the AF QoS request / update process, the AF may provide QoS monitoring requirements including PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate) to the NEF / PCF.

[0737] In some embodiments, the AF may provide a protocol description and PDU set related auxiliary information. The PDU set related auxiliary information may include QoS parameters for each QoS set within the QoS flow. The QoS parameters include at least one of the following: a PDU set processing indication, whether the application layer requires all PDUs for use of the PDU set, a PDU set delay budget, and a PDU set bit error rate. In some embodiments, the PDU set processing indication may be used to indicate whether PDU set-based processing is activated for the flow. This indication may be implicitly indicated by other PDU set related information provided by the AF.

[0738] In step 2, the PCF generates appropriate PCC rules. The PCC rules may include PDU set-related QoS parameters. The PCF may send the PCC rules to the SMF.

[0739] In some embodiments, the PCF generates an authorized QoS monitoring policy for PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate) for the service data flow based on the QoS monitoring request received from the AF.

[0740] In some embodiments, the PCF includes the authorized QoS monitoring policy for PDU set QoS parameters (e.g., PDU set delay, PDU set bit error rate / packet loss rate) in the PCC rules and provides it to the SMF.

[0741] In some embodiments, the PDU set-related QoS parameters may be new QoS parameters for PDU set-based QoS processing in 5GS, and may include at least one of the following: whether the application layer requires all PDUs for use of the PDU set, the PDU set delay budget, the PDU set bit error rate, and whether to discard the PDU set if the PDU set delay budget is exceeded.

[0742] In some embodiments, this step can be completed through some steps in the PDU session establishment process and the PDU session modification process.

[0743] In some embodiments, this may be triggered by step 1b, then the PCF may consider the information provided by the AF to generate PCC rules.

[0744] In step 3, the SMF generates the QoS configuration and N4 rules based on the PCC rules from the PCF. The SMF sends the N4 rules to the UPF and sends the QoS configuration to the RAN through the AMF.

[0745] In some embodiments, the protocol description and PDU set related auxiliary information can be sent to the SMF as part of the PCC rules. The SMF can send the protocol description and PDU set related auxiliary information to the NG-RAN through the AMF as part of the QoS configuration.

[0746] In some embodiments, this step can be completed through some steps in the PDU session establishment process and the PDU session modification process.

[0747] In step 4, the remaining steps in the PDU session establishment process and the PDU session modification process are executed.

[0748] In step 5, based on the received N4 rule or local configuration, the UPF identifies relevant information and performs QoS processing based on the PDU set according to the N4 rule instructions.

[0749] In some embodiments, the RAN / UPF is required to provide QoS monitoring results for measurements of PDU set QoS parameters (eg, PDU set delay, PDU set bit error rate / packet loss rate).

[0750] In some embodiments, the UPF identifies the PDUs that belong to a PDU set, as well as the following information for each PDU set: PDU set sequence number, start PDU or end PDU of the PDU set, PDU sequence number within the PDU set, number of PDUs within the PDU set, PDU set importance, PDU set size, and end of data burst.

[0751] In some embodiments, the UPF can identify relevant information through at least one of the following methods and / or mechanisms: matching of RTP / SRTP header and payload; new RTP extension header; information contained in the N6 encapsulation header; detection of traffic characteristics; UPF implementation of non-standardized mechanisms.

[0752] In step 6, the UPF sends the PDU set information to the RAN. The UPF sends the PDU set related information to the RAN. The UPF may add the PDU set related information to the GTP-U header.

[0753] In step 7, based on the received PDU set related information, the RAN may perform PDU set-based QoS processing.

[0754] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
