[0182] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0183] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0184] 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).

[0185] Mobile media services, cloud-based augmented reality (AR) or virtual reality (VR) services, cloud gaming, and video-based remote control of machines or drones are expected to contribute increasingly high traffic volumes to fifth-generation mobile communication technology (5G) 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.

[0186] XRM and interactive media services require the 5GS system to comprehensively consider the QoS characteristics of the relevant data flows. For example, parameters such as delay-critical guaranteed bit rate (GBR) data flows, guaranteed flow bit rate (GFBR), packet delay budget (PDB), and default maximum data burst volume (MDBV) must be met and aligned simultaneously. This also involves ensuring the consistency of QoS authorization and execution for multiple XRM data flows within a single terminal, and for XRM data flows across multiple terminals.

[0187] For example, in one embodiment of the present disclosure, a 5G system may support the application function AF to enhance the processing of XRM service data flow per PDU set. This supports the AF to enhance the QoS awareness and guarantee of XRM service data flow, as well as the user's QoE. This includes the AF providing PDU set specific QoS characteristics and protocol descriptions:

[0188] PDU sets specific QoS characteristics

[0189] PDU Set Delay Budget (PSDB).

[0190] PDU Set Error Rate (PSER).

[0191] PDU Set Integrated Handling Information (PSIHI)

[0192] The SMF and User Plane Function (UPF) can combine the protocol description and protocol header extension provided by the AF to perform the GTP-U header extension of the corresponding PDU in the corresponding SDF PDU set, carrying PDU Set information. The PDU set information is used by the NG-RAN for QoS processing based on the PDU set. The PDU set information includes:

[0193] PDU set sequence number.

[0194] Indication of the end PDU of a PDU set.

[0195] PDU sequence number in the PDU set.

[0196] PDU set size in bytes.

[0197] PDU set importance, which identifies the relative importance of a PDU set compared to other PDU sets in the QoS flow.

[0198] Compared to other ultra-low-latency services, XRM services require both ultra-low latency and ultra-high bandwidth QoS assurance. Currently, 5G systems support per-PDU set processing for XRM service data flows and congestion mechanisms such as L4S. These enhancements support enhanced QoS awareness and assurance for XRM service data flows, improving user Quality of Experience (QoE).

[0199] Optionally, in one embodiment of the present disclosure, the wireless resources on the RAN side of the radio access network are still the bottleneck of end-to-end QoS guarantee. For example, when the QoS allocation of the GBR guaranteed bandwidth of the PDU set or the non-GBR non-guaranteed bandwidth cannot be met, how to more effectively guarantee the end-to-end QoS requirements, better adapt the resource requirements and allocation, and coordinate the end-to-end (E2E) QoS resources may be a problem that the 5G system needs to support and solve. Therefore, how to effectively guarantee the end-to-end QoS requirements, better adapt the resource requirements and allocation, and coordinate the E2E QoS resources for the dynamic conditions of the wireless air interface resources, such as when the QoS allocation of the GBR guaranteed bandwidth of the PDU set or the non-GBR non-guaranteed bandwidth cannot be met.

[0200] The following describes in detail a document updating method, apparatus, device, and storage medium provided by embodiments of the present disclosure with reference to the accompanying drawings.

[0201] FIG2A is an interactive diagram of a document updating method provided by an embodiment of the present disclosure. As shown in FIG2A , the method may include the following steps:

[0202] Step S2101: The access network device updates the packet data unit (PDU) quality of service (QoS) document of the terminal's service information.

[0203] In one embodiment of the present disclosure, the access network device may be, for example, a radio access network (RAN). In some embodiments, the terms "radio," "wireless," "radio access network (RAN)," "access network (AN)," and "RAN-based" may be used interchangeably.

For example, when a parameter in the PDU set QoS profile changes, the PDU set QoS profile may also change accordingly.

[0212] In one embodiment of the present disclosure, different QoS profiles in the PDU set may correspond to different QoS levels.

[0213] Furthermore, in one embodiment of the present disclosure, updating the PDU set QoS document of the service information of the terminal includes:

[0215] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0216] The alternative PDU set QoS set (Alternative PDU set QoS Sets) may, for example, be a set including at least one PDU set QoS document. The PDU set QoS set does not specifically refer to a fixed set. For example, when the number of documents corresponding to the alternative PDU set QoS set changes, the PDU set QoS set may also change accordingly.

[0225] For example, in one embodiment of the present disclosure, a new PDU set QoS document is selected from the standby PDU set QoS set by means of resource status triggering.

[0226] For example, in one embodiment of the present disclosure, a new PDU set QoS document is selected from the standby PDU set QoS set in a manner triggered by the network congestion status.

[0227] For example, in one embodiment of the present disclosure, a new PDU set QoS document is selected from the standby PDU set QoS set by configuring a triggering manner.

[0228] For example, in one embodiment of the present disclosure, a new PDU set QoS document is selected from the standby PDU set QoS set through operator policy triggering.

[0229] For example, in one embodiment of the present disclosure, when radio resources become limited or when available radio resources are more needed, a new PDU set QoS document may be selected from the spare PDU set QoS set.

[0398] FIG6A is a flow chart of a document updating method according to an embodiment of the present disclosure. As shown in FIG6A , the embodiment of the present disclosure relates to a document updating method, which includes:

[0399] Step S6101: The radio access network (RAN) updates the Quality of Service (QoS) document of the service session / service data flow packet data unit (PDU) set of the corresponding terminal;

[0400] For example, a new PDU set QoS document in the standby PDU set QoS set may be selected.

[0401] In step S6101, the RAN sends the updated PDU set QoS document to the terminal, the 5G core network (5G Core, 5GC), and the application function (AF).

[0402] The (R)AN may select a new PDU set QoS document or an alternative PDU set parameter set based on at least one of the following:

[0403] Event triggering of QoS based on PDU set, and / or resource status, and / or network congestion status, and / or configuration and / or operator policy (e.g., when radio resources become limited, or more needed radio resources are available).

[0404] For example, in one embodiment of the present disclosure, when a new QoS profile is implemented at the RAN, the RAN may report the QoS profile of the PDU set to the terminal and the 5GC (e.g., via an initiated PDU session modification). (When a new PDU QoS profile is implemented at the RAN, the RAN reports the QoS profile of the PDU set to the Session Management Function (SMF).

[0405] For example, in one embodiment of the present disclosure, if the AF or Application server has ever subscribed to the 5GC of the current PDU est QoS document, the 5GC can report to the AF or Application server.

[0406] For example, in one embodiment of the present disclosure, through an initiated notification control, if a notification control related to a PDU set is configured for a Guaranteed Bit Rate (GBR) QoS flow, when the (R)AN decides that the PDU set QoS target of the QoS flow cannot be achieved or can be achieved again, the (R)AN can send an N2 message (PDU session ID, N2SM information) to the SMF.

[0407] For example, in one embodiment of the present disclosure, the N2SM information may include a QoS Flow Identity (QFI) and an indication that the PDU set QoS target of the QoS flow cannot be achieved or can be achieved again.

[0408] For example, in one embodiment of the present disclosure, when the PDU set QoS target cannot be achieved, the N2SM information indicates a reference to an alternative PDU set QoS profile that matches the PDU set QoS parameter value currently being implemented by the next generation radio access network NG-RAN. The Access and Mobility Management Function (AMF) can call Nsmf_PDU Session Session_UpdateSMContext (SM context ID, N2SM information). If the Policy Control Function (PCF) has subscribed to this event, the SMF reports the corresponding notification of each Policy Control and Charging (PCC) rule configuration to the PCF.

[0409] FIG7A is an interactive diagram of a document updating method according to an embodiment of the present disclosure. As shown in FIG7A , the embodiment of the present disclosure relates to a document updating method, which includes:

[0410] Step 1a, PDU session modification request;

[0426] Step 4, N2 message;

[0427] Step 5: A specific transmission resource modification (including PDU session modification command / confirmation);

[0428] Step 6, N2 message;

[0429] Step 7a, NSMF_PDU session_SM context update request;

[0430] Step 7b, NSMF_PDU Session_SM Context Update Response;

[0431] Step 8a, N4 session modification request;

[0432] Step 8b, N4 session modification response;

[0433] Step 9: PDU session modification command / confirmation;

[0434] Step 10: N2NAS uplink transmission;

[0435] Step 11a: NSMF_PDU Session_SM Context Update Request;

[0436] Step 11b: NSMF_PDU Session_SM Context Update Response;

[0437] Step 12a, N4 session modification request;

[0438] Step 12b, N4 session modification response;

[0439] Step 13: SMF starts SM policy association modification.

[0440] Wherein, step 1e includes:

[0441] (An initiated notification control) If a PDU set related notification control is configured for a GBR QoS flow, the (R)AN may send an N2 message (PDU Session ID, N2SM information) to the SMF when the (R)AN decides that the PDU set QoS target for the QoS flow cannot be achieved or can be achieved again, respectively.

[0442] In one embodiment of the present disclosure, the N2SM information includes an indication of whether the QoS target set by the QFI and PDU for the QoS flow cannot be achieved or can be achieved again.

[0443] In one embodiment of the present disclosure, when the PDU set QoS target cannot be achieved, the N2SM information indicates a reference to an alternative PDU set QoS file that matches the value of the PDU set QoS parameter currently being implemented by the next generation radio access network NG-RAN.

[0444] In one embodiment of the present disclosure, the AMF calls Nsmf_PDUSession_UpdateSMContext (SM context ID, N2SM information). If the PCF has subscribed to the event, the SMF reports the event to the PCF for each PCC rule for which notification control is set.

[0445] Wherein, step 2 includes:

[0446] The SMF may need to report some subscription events to the PCF by executing the SMF-initiated SM Policy Association Modification procedure defined in clause 4.16.5.1. If dynamic PCC is not deployed, the SMF may apply local policy to decide whether to change the QoS profile. (The SMF reports to the PCF).

[0447] Wherein, step 2a includes:

[0448] The SMF may update the UPF with the N4 rules associated with new or modified QoS flows.

[0449] Wherein, step 2b includes:

[0450] The UPF responds to the SMF.

[0451] Wherein, step 3a includes:

[0452] For a termination or an initiated modification, the SMF responds to the AMF with the Nsmf_PDUSession_UpdateSMContext response ([N2SM Information (PDU Session ID, QFI, QoS Profile, [Alternative QoS Profile], [Alternative PDU Set QoS Profile)] (it can be part of the Alternative QoS Profile or as a separate parameter), [Session AMBR], [CN Tunnel Info]), N1SM Container (PDU Session Modify Command (PDU Session ID, QoS Rule, QoS Rule Action, Required QoS Flow Document QoS Parameters for the QoS Flow associated with the QoS Rule, Session AMBR, [Always Granted on PDU Session], [Port Management Information Container]))).

[0453] In one embodiment of the present disclosure, the alternative PDU set QoS profile is valid for an initiated modification.

[0454] In one embodiment of the present disclosure, the N2SM message carries information that the AMF should provide to the (R)AN. It may include a QoS profile and a corresponding QFI to notify the (R)AN that one or more QoS flows have been added or modified, and may include the corresponding terminal status.

[0455] In one embodiment of the present disclosure, the N1SM container carries a PDU session modification command that the AMF should provide to the terminal. It may include QoS rules, QoS flow document QoS parameters required by the QoS flow associated with the QoS rule, and corresponding QoS rule operations and QoS flow document QoS parameter operations to notify the UE that one or more QoS rules have been added, deleted, or modified.

[0456] In one embodiment of the present disclosure, the SMF may need to transparently send a PDU Session Modification command over the NG-RAN to notify the UE of a change in the PDU aggregate QoS parameters currently being implemented by the NG-RAN after the SMF receives the QoS Notification Control. When the SMF transparently sends the PDU Session Modification command over the NG-RAN, the N2SM information is not included as part of the Namf_Communication_N1N2MessageTransfer.

[0457] Wherein, step 4 includes:

[0458] AMF can send N2 ([SM information received by N2 from SMF], NAS message (PDU session ID, N1SM container (PDU session modification command)) message to (R)AN.

[0459] Wherein, step 5 includes:

[0460] The (R)AN may initiate unique (R)AN-specific signaling to handle the information exchange between the terminal and the SMF. For example, in the case of NG-RAN, an RRC connection reconfiguration may be performed if the terminal modifies the necessary (R)AN resources related to the PDU session, or if only the N1SM container is received from the AMF in step 4, the RAN only transmits the N1SM container to the terminal.

[0461] In one embodiment of the present disclosure, the (R)AN may consider the updated CN-assisted RAN parameter tuning to reconfigure the AS parameters.

[0462] In one embodiment of the present disclosure, as a part thereof, an N1SM container is provided to the terminal.
