Description

Information processing method and device thereof Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an information processing method and device thereof. Background Art

[0002] Mobile media services, cloud AR (Augmented Reality) / VR (Virtual Reality) and other extended reality (XR) services, cloud gaming, and video-based remote control of machines and drones are expected to contribute increasingly high traffic volumes to 5G networks. Multimodal data describes the input of a single service / application from the same device or different devices (including sensors), which 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 data streams, 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.

[0003] Extended Reality Media (XRM) and interactive media services require the 5GS system to comprehensively consider the QoS (Quality of Service) characteristics of the relevant data flows. For example, multiple XRM data flows involving a terminal, and XRM data flows across multiple terminals, must ensure consistent QoS authorization and execution.

[0004] In related technologies, 5G systems support enhanced functionality for application functions (AF) to process XRM service data streams at the per-PDU granularity. AF also supports enhanced QoS awareness and assurance for XRM service data streams, as well as enhanced user Quality of Experience (QoE). However, given the dynamic state of wireless resources, how to more effectively guarantee end-to-end QoS requirements and better adapt to resource demand and allocation has become a pressing issue.

[0179] The 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 (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 utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0180] It's important to note that mobile media services, cloud AR (Augmented Reality) / VR (Virtual Reality) and other extended reality (XR) services, cloud gaming, and video-based remote control of machines or drones are expected to contribute increasingly high traffic to 5G networks. Multimodal data describes the input of a single service / application from the same device or different devices (including sensors), which may be output to one or more destination devices. The data streams in multimodal data often have some, or even strong, correlation, such as synchronization between audio and video streams, or tactile and visual synchronization. These media services share common characteristics within their data streams, between data streams, 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.

[0181] Extended Reality Media (XRM) and interactive media services require the 5GS system to comprehensively consider the QoS (Quality of Service) characteristics of the relevant data flows. For example, multiple XRM data flows within a single UE, and XRM data flows across multiple UEs, must ensure consistent QoS authorization and execution.

[0182] In some embodiments, the application function (AF) is supported to enhance the function of processing XRM service data streams at the protocol data unit set granularity (Per PDU set). The AF is supported to enhance the QoS perception and guarantee of XRM service data streams, as well as the user's quality of experience (QoE). Including AF providing PDU set specific QoS characteristics and protocol description (PDU Set specific QoS characteristics and Protocol Description). Among them, the PDU set specific QoS characteristics (PDU Set specific QoS characteristics) include at least one of the following: PDU Set Delay Budget (PSDB); PDU Set Error Rate (PSER); PDU Set Integrated Handling Information (PSIHI).

[0183] In some embodiments, the SMF and UPF (User Plane Function) may perform GTP-U (GPRS Tunnelling Protocol for the user plane) header extension of the corresponding PDU in the corresponding SDF (Service Data Flow) PDU (Protocol Data Unit) set in combination with the protocol description and protocol header extension provided by the AF, carrying protocol data unit set information (PDU Set Information). This PDU set information is used by the NG-RAN (access network equipment) for PDU set-based QoS processing. The PDU set information includes at least one of the following: PDU Set Sequence Number; Indication of End PDU of the PDU Set; PDU Sequence Number within a PDU Set; PDU Set Size in bytes; PDU Set Importance, which identifies the relative importance of a PDU Set compared to other PDU Sets within a QoS Flow.

[0184] Compared to other ultra-low-latency services, XRM services require both ultra-low latency and ultra-high bandwidth QoS assurance. 5G systems support per-PDU set processing for XRM service data flows and congestion mechanisms such as L4S (Low Latency, Low Loss, and Scalable Throughput). These enhancements support enhanced QoS awareness and assurance for XRM service data flows, as well as user QoE.

[0185] However, RAN-side radio resources remain a bottleneck for end-to-end QoS assurance. For example, when the allocated QoS cannot meet requirements such as PDU set latency, bandwidth, or bit error rate, the dynamic state of radio resources requires more effective end-to-end (E2E) QoS assurance, better adapting resource demand and allocation, and coordinating E2E QoS resources. These are issues that 5G systems need to address.

[0186] To this end, the embodiments of the present disclosure provide an information processing method and device thereof, which can enable the network to better adapt to resource requirements and allocation based on enhanced alternative service requirements and QoS subscription of alternative PDU sets. For the dynamic conditions of wireless resources, such as when the allocated QoS cannot be met for PDU set delay, bandwidth, or bit error rate, QoS subscription and notification based on enhanced alternative service requirements and alternative PDU sets can be used, and the QoS parameters of the alternative PDU sets can be used to better adapt to resource requirements and allocation, thereby effectively guaranteeing end-to-end QoS requirements, coordinating end-to-end QoS resources, better matching business scenarios, and ensuring QoS of business data transmission.

[0187] Figure 2 is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in Figure 2, the information processing method according to the embodiment of the present disclosure can be applied to a communication system 100, and the method includes but is not limited to the following steps.

[0188] Step S2101: The first network element 101 sends first information.

[0189] In some embodiments, the first information may be sent by the first network element 101 to the second network element 102. The second network element 102 receives the first information. For example, the first network element 101 sends the first information to the second network element 102, and the second network element 102 may receive the first information sent by the first network element 101.

[0190] In one possible implementation, the first network element 101 may send the first information to the second network element 102 via a fourth network element. The fourth network element may be, for example, a Network Exposure Function (NEF). For example, the first network element 101 may be an AF, and the second network element 102 may be a PCF. If the AF is an untrusted AF, the AF may need to send the first information to the PCF via the NEF.

[0191] In another possible implementation, the first network element 101 may send the first information to the second network element 102 via a TSCTSF (Time Sensitive Communication and Time Synchronization Function). For example, the first network element 101 is, for example, an AF, and the second network element 102 is, for example, a PCF. If the AF is a trusted AF, the AF may send the first information to the PCF via the TSCTSF.

[0192] In some embodiments, the first information may include enhanced alternative service requirements and an alternative PDU set QoS subscription. The enhanced alternative service requirements are used by the second network element 102 to generate policy and charging control (PCC) rules; and the alternative PDU set QoS subscription is used to enable PDU set QoS notification control. In some embodiments, "alternative PDU set QoS subscription" may also be referred to as "subscribing to an alternative PDU set QoS notification," or "alternative PDU set QoS subscription."

[0193] In some embodiments, the first information may be Nnef_AFsessionWithQoS_Create request (create AF session with specific QoS) request information. In some embodiments, the first information may be included in Nnef_AFsessionWithQoS_Create request information.

[0194] Exemplarily, the AF sends an AF session resource request, such as a CreateAF request (also called a QoS-specific AF session request) message via the Nnef_AFsessionWithQoS_Create request. The AF includes in the request enhanced alternative service requirements and the QoS subscription for the alternative PDU set. The enhanced alternative service requirements can be understood as QoS requirements for XRM and interactive media service data flows.

[0195] In some embodiments, the above-mentioned enhanced alternative service requirements may include but are not limited to at least one of the following: one or more PDU set QoS reference parameters; one or more priorities of the PDU set QoS reference parameters; one or more alternative PDU set QoS parameter sets; one or more priorities of the alternative PDU set QoS parameter sets. Among them, the PDU set QoS reference parameters may be the PDU set QoS parameters pre-agreed between the first network element and the network, and the first network element and the network side pre-agreed on the first network element and the network side and their corresponding parameter values. In this way, when the first network element requests QoS resources from the network, it can provide the PDU set QoS reference parameters to the network through the enhanced alternative service requirements, and the network side determines the parameter values ​​corresponding to the PDU set QoS reference parameters based on the PDU set QoS reference parameters provided by the first network element.

[0196] Among them, the first network element provides the priority of the PDU set QoS reference parameter to the network side, so that the network side can allocate corresponding QoS resources according to the priority. For example, the enhanced alternative service requirement includes two PDU set QoS reference parameters, such as PDU set QoS reference parameter 1 and PDU set QoS reference parameter 2. The priority of PDU set QoS reference parameter 1 is higher than the priority of PDU set QoS reference parameter 2. The network side can first allocate QoS resources to the first network element based on PDU set QoS reference parameter 1. When PDU set QoS reference parameter 1 cannot meet the PDU set QoS target (such as the current network cannot meet the parameter value corresponding to the PDU set QoS reference parameter 1), the network side can allocate QoS resources to the first network element based on PDU set QoS reference parameter 2.

[0197] Among them, the above-mentioned alternative PDU set QoS parameter set can be the alternative PDU set QoS parameter set required by the first network element (which can also be understood as requested, needed, or required). Exemplarily, the first network element can determine the required QoS parameter value to suit the current scenario based on factors such as the business scenario, and the first network element can provide the required QoS parameter value to the network in the form of an alternative PDU set QoS parameter set, so that the network side can allocate QoS resources to the first network element based on the alternative PDU set QoS parameter set required by the first network element. Thus, the first network element provides the PDU set QoS reference parameters and / or the alternative PDU set QoS parameter set required by the first network element to the network side through the enhanced alternative service requirements, so that the network side can adapt the QoS resources based on the PDU set QoS reference parameters in the enhanced alternative service requirements and / or the alternative PDU set QoS parameter set required by the first network element. During the whole process, the first network element only needs to initiate a request session, avoiding the first network element from initiating multiple request sessions and avoiding unnecessary multiple interactions between the first network element and the network side.

[0198] Exemplarily, taking the first network element as AF as an example, in addition to the PDU set QoS reference parameters and / or the separate PDU set QoS parameters, the AF can also provide the enhanced alternative service requirements in priority order (wherein the priority order can indicate the preference of the PDU set QoS requirements). That is, the AF can provide enhanced alternative service requirements, which can include, in addition to the PDU set QoS reference parameters and / or the separate PDU set QoS parameters (such as the alternative PDU set QoS parameter set), the priority of the PDU set QoS reference parameters and / or the priority of the separate PDU set QoS parameters (such as the alternative PDU set QoS parameter set), wherein the PDU set QoS reference parameters and / or the separate PDU set QoS parameters (such as the alternative PDU set QoS parameter set) can be sorted in priority order (such as from high to low, or from low to high).

[0199] Exemplarily, when AF requests the network to provide a PDU set QoS reference to the PDU set QoS, the enhanced alternative service requirement may include: one or more PDU set QoS reference parameters, wherein the one or more PDU set QoS reference parameters may be arranged by priority. For example, taking the enhanced alternative service requirement as including PDU set QoS reference parameter 1 and PDU set QoS reference parameter 2, and the priority of PDU set QoS reference parameter 2 is higher than the priority of PDU set QoS reference parameter 1, assuming that it is agreed that the PDU set QoS reference parameter with a higher priority is arranged in front, the order of the PDU set QoS reference parameters in the enhanced alternative service requirement should be: PDU set QoS reference parameter 2, PDU set QoS reference parameter 1.

[0200] Exemplarily, when the AF requests the network to provide a separate PDU set QoS parameter for the PDU set QoS, the enhanced alternative service requirement may also include: one or more alternative PDU set QoS parameter sets, wherein the one or more alternative PDU set QoS parameter sets may be arranged in priority. For example, taking the example that the enhanced alternative service requirement also includes alternative PDU set QoS parameter set 1 and alternative PDU set QoS parameter set 2, and the priority of alternative PDU set QoS parameter set 2 is higher than the priority of alternative PDU set QoS parameter set 1, assuming that the alternative PDU set QoS parameter set with a higher priority is arranged in front, the order of the alternative PDU set QoS parameter sets in the enhanced alternative service requirement should be: alternative PDU set QoS parameter set 2, alternative PDU set QoS parameter set 1.

[0201] In some embodiments, the parameters in each candidate PDU set QoS parameter set include at least one of the following: packet set delay budget (PSDB); packet set error rate (PSER); PDU set integrated processing information (PSIHI); uplink (UL) guaranteed bit rate; downlink (DL) guaranteed bit rate; averaging window; and maximum data burst size. In this embodiment, each candidate PDU set QoS parameter set may include: PSDB; in this embodiment, each candidate PDU set QoS parameter set may include: PSER; in this embodiment, each candidate PDU set QoS parameter set may include: PSIHI; in this embodiment, each candidate PDU set QoS parameter set may include: UL guaranteed bit rate; in this embodiment, each candidate PDU set QoS parameter set may include: DL guaranteed bit rate; in this embodiment, each candidate PDU set QoS parameter set may include: averaging window; in this embodiment, each candidate PDU set QoS parameter set may include: maximum data burst size. Optionally, the parameters in each candidate PDU set QoS parameter set may be the same or different. It should be noted that the above embodiments are not exhaustive and are only illustrations of some embodiments. The above embodiments can be implemented individually or in combination. The above embodiments are only for illustration and are not intended to be a specific limitation on the scope of protection of the embodiments of the present disclosure.

[0202] For example, taking multiple alternative PDU set QoS parameter sets including alternative PDU set QoS parameter set 1, alternative PDU set QoS parameter set 2 and alternative PDU set QoS parameter set 3 as an example, alternative PDU set QoS parameter set 1 may include PSDB parameters; alternative PDU set QoS parameter set 2 may include PSER parameters; alternative PDU set QoS parameter set 3 may include UL guaranteed bit rate parameters.

[0203] In some embodiments, the QoS subscription of the above-mentioned alternative PDU set may include but is not limited to at least one of the following: subscription to QoS change notification of the alternative PDU set; subscription to notification that at least one alternative PDU set cannot meet QoS; subscription to QoS parameter set that the lowest priority alternative PDU set cannot meet. In this embodiment, the QoS subscription of the above-mentioned alternative PDU set may include subscription to QoS change notification of the alternative PDU set; in this embodiment, the QoS subscription of the above-mentioned alternative PDU set may include subscription to notification that at least one alternative PDU set (such as all alternative PDU sets) cannot meet QoS; in this embodiment, the QoS subscription of the above-mentioned alternative PDU set may include subscription to QoS parameter set that the lowest priority alternative PDU set cannot meet. It should be noted that the above-mentioned embodiments are not exhaustive, but are only illustrative of some embodiments, and the above-mentioned embodiments may be implemented individually or in combination. The above-mentioned embodiments are only for illustration and are not for specific limitation on the scope of protection of the embodiments of the present disclosure.

[0204] Optionally, in some embodiments, the above-mentioned first information may further include at least one of the following: XRM service information; identification information of the XRM service data flow or data flow group; terminal address (UE address) and / or terminal identification (UE Identifier) ​​information; first network element 101 application identification information (AF Identifier Application ID); XRM service data flow description (Flow description(s)) information; data network name (Data Network Name, DNN); single network slice selection assistance information (S-NSSAI); QoS parameters (QoS parameters) of the XRM service data flow. Exemplarily, the identification information of the XRM service data flow or data flow group may be a multi-modal service ID (multi-modal service identifier), which can be used to identify all data flows (flows) in the XRM service group (XRM service group).

[0205] Step S2102: The second network element 102 obtains first information and generates a PCC rule based on the first information.

[0206] In some embodiments, the second network element 102 can obtain the first information sent by the first network element 101 from the NEF. Exemplarily, the first network element 101 is, for example, an AF, and the second network element 102 is, for example, a PCF. If the AF is an untrusted AF, the AF needs to provide the first information to the PCF via the NEF. Exemplarily, the AF can provide the first information to the NEF via the Nnef_AFsessionWithQoS_Create request. Optionally, the NEF performs relevant mappings, including mapping the XRM service (AF-Service-Identifier) ​​to the DNN and S-NSSAI, mapping external applications to CN (Core Network) application identifiers; and based on UDM (Unified Data Management) subscription information, mapping external UE identifiers to CN internal UE identifiers (such as User Permanent Identifier SUPI), and performing external to internal XRM service group identifier mapping based on the UDM subscription information. After the NEF performs the relevant mappings, the NEF authorizes the AF request and directly provides the first information to the PCF. Exemplarily, the NEF triggers Npcf_PolicyAuthorization_Create request (create policy authorization request) and sends the first information to the PCF. The PCF receives the first information sent by the AF from the NEF, so that the PCF can execute the policy decision.

[0207] In some embodiments, the second network element 102 may obtain the first information sent by the first network element 101 from the TSCTSF. For example, the first network element 101 is, for example, an AF, and the second network element 102 is, for example, a PCF. If the AF is a trusted AF, the AF may send the first information to the PCF via the TSCTSF. For example, the AF may provide the first information to the NEF via the Nnef_AFsessionWithQoS_Create request. The NEF authorizes the AF request and determines to call the TSCTSF based on the parameters provided by the AF to establish the AF session through the required QoS process. The PCF receives the first information sent by the AF from the TSCTSF for PCF policy decision-making.

[0208] In some embodiments, the second network element 102 is, for example, a PCF, which can be used to make policy decisions. The PCF can determine that updated or new policy information needs to be sent to the third network element 103 (such as an SMF). The policy information can be represented by a PCC rule. That is, after the second network element 102 obtains the above-mentioned first information, the second network element 102 can make a policy decision based on the first information and generate corresponding PCC rules. In some embodiments, the second network element 102 can generate PCC rules based on the PDU set QoS reference parameters and / or the alternative PDU set QoS parameter set in the enhanced alternative service requirements in the first information. Optionally, the PCC rule includes an alternative PDU set QoS parameter set.

[0209] Step S2103 , the second network element 102 enables PDU set QoS notification control.

[0210] In some embodiments, the second network element 102 may enable PDU set QoS notification control. Optionally, in some embodiments, when the QoS of the alternative PDU set needs to be changed, the second network element 102 may send a second message to the first network element 101, the second message being used to notify that the PDU set QoS target can no longer be met. When the alternative PDU set cannot meet the QoS, the second network element 102 may send a second message to the first network element 101, being used to notify that the PDU set QoS target can no longer be met. When the lowest priority alternative PDU set cannot meet the QoS parameter set, the second network element 102 may send a second message to the first network element 101, being used to notify that the PDU set QoS target can no longer be met.

[0211] For example, taking the second network element 102 as PCF and the first network element 101 as AF, when the PCF notifies the AF that the PDU set QoS target can no longer be met, the PCF can send second information, which may include but is not limited to at least one of the following: PDU set QoS reference parameters; a requested alternative PDU set QoS parameter set corresponding to the alternative PDU set QoS parameter set referenced by the SMF; an indication of the lowest priority PDU set QoS reference or the lowest priority set of alternative PDU set QoS parameters that cannot meet the enhanced alternative service requirements.

[0212] In step S2104 , the second network element 102 sends the generated PCC rule to the third network element 103 .

[0213] Optionally, the second network element 102 may send a PCC rule including an alternative PDU set QoS parameter set to the third network element 103. Exemplarily, the alternative PDU set QoS parameter sets included in the PCC rule sent by the second network element 102 may be sorted in the same priority order as indicated by the first network element 101 (e.g., AF).

[0214] Step S2105 : The third network element 103 determines QoS rules and QoS set parameters based on the PCC rules.

[0215] In some embodiments, the above-mentioned QoS rules and QoS set parameters are used to configure and / or activate PCC rules to a user plane function (UPF).

[0216] In some embodiments, the second network element 102 may initiate an SM policy association modification request (PCC rule) to the third network element 103. Upon receiving the PCC rule, the third network element 103 may determine a QoS rule and QoS set parameters to configure and / or activate the PCC rule for the UPF. For example, the third network element 103 may establish an N4 session with the UPF and configure and / or activate the PCC rule for the UPF via the N4 session.

[0217] In some embodiments, the third network element 103 obtains the QoS parameters of the QoS flow based on PCC rule information of the PCC rule bound to the QoS flow.

[0218] In step S2106, if the PCC rule includes an alternative PDU set QoS parameter set, the third network element 103 provides the PDU set QoS parameters of the QoS flow and provides the attributes of the alternative PDU set QoS parameter set as an alternative PDU set QoS profile in the same priority order.

[0219] That is, if the PCC rule includes an alternative PDU set QoS parameter set, the third network element 103 should provide its attributes as a QoS profile of the alternative PDU set in the same priority order in addition to providing the PDU set QoS parameters of the QoS flow.

[0220] Step S2107 : The PCC rule includes an alternative PDU set QoS parameter set, and the third network element 103 provides the access network device 104 with an alternative PDU set QoS profile and a priority list of the alternative QoS profiles.

[0221] That is, if the PCC rule includes an alternative PDU set QoS parameter set, in addition to the QoS profile, the third network element 103 should also provide a priority list of alternative QoS profiles to the access network device 104 (such as NG-RAN).

[0222] Step S2108 : The access network device 104 obtains a new priority list of candidate QoS profiles provided by the third network element 103 .

[0223] In some embodiments, the third network element 103 may provide the priority list of the alternative QoS profiles and the QoS profile to the access network device 104. If the third network element 103 provides the access network device 104 with a new priority list of the alternative QoS profiles (if the corresponding PCC rule information changes), the access network device 104 may obtain the new priority list of the alternative QoS profiles from the third network element 103.

[0224] In step S2109 , the access network device 104 updates the priority list of any previously stored candidate QoS profiles based on the new priority list.

[0225] That is, if the third network element 103 provides the access network device 104 with a new priority list of alternative QoS profiles (if the corresponding PCC rule information changes), the access network device 104 may replace any previously stored list with it.

[0226] In some embodiments, a candidate PDU set QoS profile represents a combination of PDU set QoS parameters to which the application service can adapt.

[0227] Optionally, taking the third network element 103 as an SMF, the SMF may need to report some subscribed events to the PCF by executing the SMF-initiated SM policy association modification process. If dynamic PCC is not deployed, the SMF can apply local policies to decide whether to change the QoS profile. (The SMF reports to the PCF).

[0228] In some embodiments, the access network device 104 does not meet the PDU set QoS profile and sends a first notification to the third network element 103; the first notification includes a reference to the alternative PDU set QoS profile to indicate the PDU set QoS currently met by the access network device. Exemplarily, when the access network device 104 sends the notification of not meeting the PDU set QoS profile to the SMF, the access network device 104 includes a reference to the alternative PDU set QoS profile to indicate the PDU set QoS currently met by the NG-RAN.

[0229] In some embodiments, the access network device 104 fails to meet the lowest priority alternative PDU set QoS profile and sends a second notification to the third network element 103; the second notification includes a PDU set QoS notification control indicating whether to request a notification from the access network when the PDU set QoS of the QoS flow can no longer or can be guaranteed again during the life cycle of the QoS flow. Exemplarily, when the access network device 104 cannot meet even the least preferred alternative PDU set QoS profile, the access network device 104 sends a notification to the SMF. The notification can be a PDU set QoS notification control indicating whether to request a notification from the access network when the PDU set QoS of the QoS flow can no longer (or can be) guaranteed during the life cycle of the QoS flow.

[0365] In some embodiments, the above method may include the method described in the above embodiments of the first network element side, the second network element side, the third network element side, the access network device side, etc., which will not be repeated here.

[0366] In response to the dynamic conditions of wireless resources, such as when the allocated QoS cannot be met for PDU set delay, bandwidth, or bit error rate, the present disclosure adds an alternative PDU set QoS subscription and notification. The AF provides the alternative PDU set QoS requirements and subscribes to the QoS change notification of the alternative PDU set, and / or the notification of all the Alternative PDU set QoS cannot be fulfilled (the lowest priority Alternative PDU set QoS parameter set cannot be fulfilled). This can more effectively guarantee end-to-end QoS requirements, better adapt to resource requirements and allocation, and coordinate end-to-end QoS resources. As shown in Figure 7, the alternative PDU set QoS subscription and notification process may include but is not limited to the following steps.

[0367] In step S1, the AF sends an AF session resource request, for example, via the Nnef_AFsessionWithQoS_Create request. The AF includes the enhanced alternative service requirements and the alternative PDU set QoS subscription in the request message. The enhanced alternative service requirements can be understood as the QoS requirements for XRM and interactive media service data flows.

[0368] In some embodiments, in addition to the PDU set QoS reference or separate PDU set QoS parameters, the AF may also provide enhanced alternative service requirements in priority order (indicating the preference of the PDU set QoS requirements), wherein the enhanced alternative service requirements include at least one of the following:

[0369] When the AF requests the network to provide PDU set QoS with a PDU set QoS Reference, one or more PDU set QoS Reference parameters in a prioritized order;

[0370] When the AF requests the network to provide PDU set QoS with individual PDU set QoS parameters, one or more Requested Alternative PDU set QoS Parameter Set(s) in a prioritized order. The parameters in each requested alternative PDU set QoS parameter set may include, but are not limited to, at least one of the following: packet set delay budget, packet set error rate, PSIHI, UL guaranteed bit rate, DL guaranteed bit rate, averaging window, and maximum data burst size.

[0371] Optionally, in some embodiments, the AF request may also carry XRM service information, identifying the XRM service data flow or data flow group (e.g., multi-modal service ID), terminal address (UE address) and / or terminal identification (UE Identifier) ​​information, AF Identifier Application ID (AF application identification information), Flow description(s) (flow description), DNN, S-NSSAI, QoS parameters (QoS parameters), and other corresponding information. Here, the multi-modal service ID can be used to identify all data flows in the XRM service group (XRM service group).

[0372] In step S2, the NEF authorizes the AF request. If the AF 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 identifier (AF-Service-Identifier) ​​to the DNN and S-NSSAI, mapping the external application to the CN application identifier; and mapping the external UE identifier to the CN internal UE identifier (such as SUPI) based on the UDM subscription information, as well as performing external to internal XRM service group identifier mapping based on the UDM subscription information.

[0373] In step S3, the NEF authorizes the AF request and, based on the parameters provided by the AF, determines whether to invoke the TSCTSF or contact the PCF directly. (These signaling steps are used to establish the AF session with the required QoS procedures.) The PCF receives the AF-provided attributes from the NEF or TSCTSF. The NEF triggers an Npcf_PolicyAuthorization_Create request, sending the AF request to the PCF with the QoS requirements for the PCF policy decision.

[0374] In step S4, the PCF makes a policy decision and may determine that updated or new policy information needs to be sent to the SMF.

[0375] In some embodiments, the PCF derives the alternative PDU set QoS parameter set for the PCC rule based on the PDU set QoS reference parameters in the enhanced alternative service requirements or the requested alternative PDU set QoS parameter set.

[0376] In some embodiments, the PCF enables PDU set QoS Notification Control and includes the derived Alternative PDU set QoS parameter sets (in the same prioritized order indicated by the AF) in the PCC rule sent to the SMF.

[0377] In some embodiments, when the PCF notifies the AF that the PDU set QoS targets can no longer be met, the PCF shall include an indication of the lowest priority PDU set QoS reference parameters or the requested alternative PDU set QoS parameter set corresponding to the alternative PDU set QoS parameter set referenced by the SMF, or the lowest priority PDU set QoS reference or the requested alternative PDU set QoS parameters that cannot meet the enhanced alternative service requirements.

[0378] Step S5: The PCF responds to the NEF with an Npcf_PolicyAuthorization_Create response.

[0379] Step S6: The NEF sends an Nnef_AFsessionWithQoS_Create response message to the AF, which may carry a result to inform whether the request is authorized.

[0380] Step S7: The PCF initiates an SM Policy Association Modification Request (PCC rule) to the SMF. The SM Policy Association Modification Request may be an Npcf_SMPolicyControl_UpdateNotify request.

[0381] In some embodiments, upon receiving the PCC rules, the SMF determines the QoS rules and QoS setting parameters to configure / activate the PCC rules to the UPF (e.g., via the N4 session).

[0382] In some embodiments, the SMF derives the QoS parameters of the QoS flow based on the PCC rule information of the PCC rule bound to the QoS flow. If the PCC rule contains an alternative PDU set QoS parameter set, the SMF shall provide its attributes as the QoS profile of the alternative PDU set in the same priority order in addition to the PDU set QoS parameters of the QoS flow.

[0383] In some embodiments, the SMF derives the QoS parameters of the QoS flow based on the PCC rule information of the PCC rule bound to the QoS flow. If the PCC rule contains an alternative PDU set QoS parameter set, the SMF shall provide a priority list of alternative QoS profiles to the NG-RAN in addition to the QoS profile.

[0384] Step S8: SMF replies to PCF with an SM policy association modification response.

[0385] In step S9, the SMF triggers the PDU session modification process and provides the QoS profile and a prioritized list of Alternative QoS Profile(s) to the NG-RAN.

[0386] In some embodiments, if the SMF provides the NG-RAN with a new prioritized list of alternative QoS profiles (if the corresponding PCC rule information changes), the NG-RAN will replace any previously stored list with it.

[0387] In some embodiments, the candidate PDU set QoS profile represents a combination of PDU set QoS parameters to which the application service can adapt.

[0388] Step S10, (AN initiated notification control) If notification control associated with a PDU set is configured for the QoS flow, the (R)AN sends an N2 message (PDU session ID, N2SM information) to the SMF when the (R)AN decides that the PDU set QoS target of the QoS flow cannot be achieved or can be achieved again.

[0389] In some embodiments, the N2SM information includes a QFI (QoS Flow Identity) and an indication that the PDU Set QoS targets for the QoS flow cannot be achieved or can be achieved again. When the PDU Set QoS targets cannot be met, the N2SM information indicates a reference to an alternative PDU Set QoS profile that matches the values ​​of the PDU Set QoS parameters currently being achieved by the NG-RAN.

[0390] In some embodiments, AMF calls Nsmf_PDUSession_UpdateSMContext (SM context ID, N2SM information). If PCF has subscribed to this event, SMF reports this event to PCF for each PCC rule for which notification control is set.

[0391] In step S11, the SMF may need to report some subscribed events to the PCF by executing the SMF-initiated SM policy association modification process. If dynamic PCC is not deployed, the SMF can apply local policies to decide whether to change the QoS profile. (The SMF reports to the PCF).

[0392] In some embodiments, when the NG-RAN sends a notification to the SMF that a PDU Set QoS profile is not met, the NG-RAN includes a reference to an alternative PDU Set QoS profile to indicate the PDU Set QoS currently met by the NG-RAN.

[0393] In some embodiments, when the NG-RAN node cannot satisfy even the least preferred alternative PDU Set QoS profile, the NG-RAN sends a notification to the SMF. In some embodiments, the notification may be a PDU Set QoS Notification Control, which indicates whether to request a notification from the access network when the PDU Set QoS for a QoS Flow can no longer (or can again) be guaranteed during the lifetime of the QoS Flow.

[0394] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods.
