[0125] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0126] To ensure a high-quality user experience for key 5G services such as mainstream live streaming and cloud gaming, current 5G networks utilize the Network Data Analytics Function (NWDAF) to establish a complete closed-loop mechanism. This loop begins with "experience assessment of services," accurately assessing user experience for specific services. It then optimizes service quality (QoS) based on the assessment results, making targeted adjustments. Finally, it verifies the effectiveness of these optimizations through "experience perception evaluation," ensuring a superior user experience. This cycle repeats continuously, providing users with stable and smooth 5G services for key services. (See also...) Figure 1The business processes implemented based on NWDAF include:

[0127] 1. Service Subscription: NWDAF completes the configuration of service subscription information locally. During this process, the system records the relevant details of the services subscribed by the user, providing basic data for subsequent processes.

[0128] 2. Data Collection: Based on the configured business subscription information, NWDAF will automatically trigger requests to the User Plane Function (UPF) to subscribe to data collection. The UPF will then determine the types and scope of data to be collected based on these requests.

[0129] 3. Data Reporting and Experience Statistics: When a user uses the service, the UPF (User-Generated Function) begins operation. It matches the actual collected data (such as latency, bandwidth, packet loss, and other key metrics) with the previously set data collection requirements. If a match is successful, the UPF analyzes this data to determine the current service experience and reports the analysis results to the NWDAF (User-Generated User Experience AF). Subsequently, the NWDAF compiles and summarizes this user experience data from the UPF, providing data support for subsequent strategy development.

[0130] 4. Service Experience Strategy Recommendations: When evaluating service experience, NWDAF comprehensively considers factors such as Guaranteed Bit Rate (GBR) resource information and user guarantee quotas. Based on these considerations, NWDAF generates corresponding guarantee strategy recommendations and sends them to the Policy Control Function (PCF).

[0131] 5. Dedicated Bearer Establishment: After receiving the protection policy recommendations from NWDAF, PCF performs decision analysis and generates dynamic GBR rules. Once generated, these rules trigger the dedicated bearer establishment process, thereby providing users with higher-quality and more stable network bearer services for their specific businesses and ensuring a better user experience.

[0132] However, with the development of XR immersive communication services such as Virtual Reality (VR) videos and Augmented Reality (AR) glasses, users' demands for network bandwidth and latency have further increased, and the network is facing a particular problem of bandwidth resource shortage. Therefore, the 3rd Generation Partnership Project (3GPP) began to introduce XR frame guarantee technology, which flexibly identifies XR service frames through the 5G network and performs frame-level transmission scheduling, thereby increasing the number of terminal accesses by saving air interface resources and optimizing the smoothness and clarity of XR services, such as stuttering, screen tearing, and black borders.

[0133] See Figure 2 One of the key technologies in 3GPP Release 18's research on Extended Reality Management (XRM) is frame-granular QoS assurance. Its basic principle is the definition of a "frame (a set of one or more Protocol Data Units (PDUs))", meaning a frame (such as voice frames, I / P / B, or other types of video frames) is composed of several related PDU messages. Furthermore, 3GPP has correspondingly extended the frame-granular QoS mechanism, including the following advancements:

[0134] (1) The Session Management Function (SMF) sends PDU Set QoS parameters to the Radio Access Network (RAN), which mainly include:

[0135] –PDU Set Delay Budget (PSDB);

[0136] –PDU Set Error Rate (PSER);

[0137] –PDU Set Handling Indication (PSIHI).

[0138] (2) The Session Management Function (SMF) sends a PDU Set Marking Indication (PDUSM) to the UPF, instructing the UPF to enable frame recognition and marking.

[0139] (3) UPF can flexibly identify service frames such as voice and video through methods such as Deep Packet Inspection (DPI) and parse them to obtain PDU Set information, which mainly includes:

[0140] - Packet Sequence Number (PSSN);

[0141] –End of PDU in Frame (EPDU);

[0142] - Packet Sequence Number (PSI).

[0143] (4) The UPF transmits the frame information to the RAN through the General Packet Radio Service Tunneling Protocol-User Plane (GTP-U) extended packet header. The RAN then performs frame-level scheduling based on the PDU Set QoS parameters issued by the SMF, achieving two aspects of frame protection:

[0144] First, frame integrity is guaranteed: by identifying information such as the PDU Set sequence number and the PDU Set end marker, the base station determines whether to discard the frame;

[0145] Second, frame differentiation guarantee: By identifying the importance sequence number of PDU Set, the base station determines whether to prioritize the transmission of more important frames (such as video I-frames) and discard less important frames (such as video P / B frames) when resources such as bandwidth are limited.

[0146] In summary, for video businesses such as influencer live streaming, Figure 1 The technologies involved assume sufficient bandwidth resources, thus increasing the relative priority of services. Furthermore, considering that XR services such as VR and AR can easily lead to bandwidth shortages, Figure 2 The technology involved prioritizes the transmission of key frames to ensure a better user experience.

[0147] However, in related technologies, at the 5G core network (5GC) policy control level, there is a lack of flexible combination guarantee mechanisms at the stream level (e.g., whether to enable dedicated transport channels) and frame level (e.g., whether to enable frame function guarantees), which prevents XR services from providing a good presentation effect. Based on the above issues:

[0148] This application provides a service assurance method applied to a first node device. See also... Figure 3 , Figure 3 This is a flowchart of the service assurance method provided in the embodiments of this application, such as... Figure 1 As shown, it includes the following steps:

[0149] Step 301: Receive first information sent by the second node device. The first information includes at least one of the service bandwidth data of the target service and the congestion data of the base station corresponding to the target service. The target service includes extended reality (XR) service. The service bandwidth data includes the service bandwidth ratio of the target service and the frame bandwidth ratio of the target service. The service bandwidth ratio is used to indicate the proportion of communication bandwidth occupied by the target service in the total communication bandwidth. The frame bandwidth ratio is used to indicate the proportion of communication bandwidth occupied by each type of frame image data of the target service in the total communication bandwidth. The bandwidth ratio threshold includes a service bandwidth ratio threshold and a frame bandwidth ratio threshold.

[0150] In this step, the target service can include both XR and non-XR services. The service bandwidth data for the target service includes its service bandwidth, bandwidth percentage, frame type, frame bandwidth, and frame bandwidth percentage. The service bandwidth percentage is the proportion of communication bandwidth occupied by the target service within the total communication bandwidth. The data granularity of the service bandwidth percentage can be at the flow, session, user equipment (UE) level, or cell level. Frame types can include voice frames, video I-frames, video P-frames, and video B-frames, etc. Frame bandwidth is the bandwidth required to transmit each type of frame data. The frame bandwidth percentage indicates the proportion of communication bandwidth occupied by each type of frame image data of the target service within the total communication bandwidth. The total communication bandwidth is the communication bandwidth of the user where the target service is located, the communication bandwidth of the cell where it is located, the communication bandwidth of the base station where it is located, or the communication bandwidth of the network where it is located.

[0151] The congestion data of the base station corresponding to the target service includes the number of users accessing the cell and the physical resource block occupancy rate.

[0152] In addition, the second node device can also send other parameters, such as frame latency and frame packet loss.

[0153] The first node device can be understood as a service analysis node device, and the second node device can be understood as a service reporting node device. If the NWDAF is a service analysis node device, then the NWDAF can subscribe to reporting to the service reporting node device UPF or RAN as a subscriber; if the UPF is a service analysis node device, then the UPF can subscribe to reporting to the service reporting node device RAN as a subscriber.

[0154] Step 302: Based on the first information, determine the service assurance strategy for the target service. The service assurance strategy includes at least one of establishing a communication resource allocation channel for the target service and providing frame-level quality of service (QoS) assurance for the target service.

[0155] In this step, the degree of network congestion can be determined based on the congestion data of the base station corresponding to the target service; the impact of the target service on the overall network bandwidth can be determined based on the service bandwidth ratio of the target service in the service bandwidth data; and the bandwidth ratio of the target service in the frame bandwidth data can be determined based on the bandwidth ratio of the various types of frames transmitted by the target service.

[0156] If the congestion level is low, it indicates sufficient bandwidth resources. To ensure the priority of the target service (such as XR service), a communication resource allocation channel, such as a dedicated load channel, can be established for the target service. If the congestion level is moderate, with a low proportion of service bandwidth but a high proportion of frame bandwidth, it indicates that the target service has little overall impact on network bandwidth, but a large proportion of unimportant frames. To ensure the priority of the target service while saving bandwidth resources, a communication resource allocation channel, such as a dedicated load channel, can be established for the target service, and frame-level QoS guarantees can be provided for the target service. If the congestion level is high, it indicates that bandwidth resources are tight. On the basis of ensuring fairness among multiple services, the target service can be optimized, and a communication resource allocation channel, such as a default load channel, can be established for the target service, while saving bandwidth usage and providing frame-level QoS guarantees for the target service.

[0157] Step 303: Send the service assurance policy of the target service to the third node device.

[0158] In this step, the third node device can be understood as a service processing node device. If the first node device is an NWDAF (Network Window AF), the third node device can be a PCF (Processing Center AF); if the first node device is a UPF (User Window AF), the third node device can be a RAN (Radio Array AF). Service assurance policies can be sent through a QoS profile and PDU Set QoS parameters. The QoS profile includes policies on whether to establish communication resource allocation channels for the target service, and the PDU Set QoS parameters include policies on whether to provide frame-level QoS guarantees for the target service.

[0159] In one embodiment, the system receives first information sent by a second node device. The first information includes at least one of service bandwidth data for a target service and congestion data for a base station corresponding to the target service. The target service includes Extended Reality (XR) service. The service bandwidth data includes the service bandwidth percentage of the target service and the frame bandwidth percentage of the target service. The service bandwidth percentage indicates the proportion of communication bandwidth occupied by the target service in the total communication bandwidth. The frame bandwidth percentage indicates the proportion of communication bandwidth occupied by each type of frame image data of the target service in the total communication bandwidth. The bandwidth percentage threshold includes a service bandwidth percentage threshold and a frame bandwidth percentage threshold. Based on the first information, the system determines a service assurance strategy for the target service. The service assurance strategy includes at least one of establishing a communication resource allocation channel for the target service and providing frame-level Quality of Service (QoS) assurance for the target service. The system then sends the service assurance strategy for the target service to a third node device.

[0160] In this implementation, the service bandwidth ratio and frame bandwidth ratio in the service bandwidth data of the target service are defined, and flexible service assurance strategies at the flow level (whether to establish a communication resource allocation channel for the target service) and frame level (whether to enable frame function protection for the target service) are formulated based on the service bandwidth data of the target service and the congestion data of the base station corresponding to the target service. This balances the use of network resources and the quality assurance of the target service, which is conducive to enabling the target service to provide a better presentation effect.

[0161] Optionally, determining the service assurance strategy for the target service based on the first information includes:

[0162] Based on the pre-set congestion threshold data and the congestion data, the congestion level of the base station where the target service is located is determined;

[0163] Based on the pre-set bandwidth percentage threshold data, the service bandwidth data, and the congestion level, the service assurance strategy for the target service is determined.

[0164] In one implementation, the first node device can pre-set bandwidth occupancy threshold data and congestion threshold data. The bandwidth occupancy threshold data is used to measure the service bandwidth data of the target service; the congestion threshold data is used to measure the congestion data of the base station corresponding to the target service, and the congestion threshold data can be determined based on the number of PRBs in the cell, the maximum number of access users, and the bandwidth utilization rate, etc.

[0165] Based on pre-set congestion threshold data and real-time monitored congestion data of the base station corresponding to the target service, the congestion level of the base station where the target service is located can be determined. For example, the pre-set congestion threshold data is a cell PRB occupancy rate of 70%. If the cell PRB occupancy rate of the base station corresponding to the target service reaches 70%, it indicates that the base station corresponding to the target service is congested.

[0166] Furthermore, the service bandwidth data includes service bandwidth percentage data and frame bandwidth percentage data, and the bandwidth percentage threshold data can include service bandwidth percentage threshold data and frame bandwidth percentage threshold data. Comparing the service bandwidth percentage data with the service bandwidth percentage threshold data can determine the service bandwidth percentage of the target service; comparing the frame bandwidth percentage data with the frame bandwidth percentage threshold data can determine the frame bandwidth percentage of the target service.

[0167] Then, based on the proportion of service bandwidth of the target service, the proportion of frame bandwidth of the target service, and the congestion level of the base station corresponding to the target service, the service guarantee strategy for the target service can be determined (whether to establish a communication resource allocation channel for the target service and whether to enable frame function guarantee for the target service).

[0168] In this implementation, the accuracy of the business assurance strategy formulation for the target business can be improved by using pre-set congestion threshold data and bandwidth ratio threshold data, as well as real-time acquired service bandwidth data and congestion data.

[0169] Optionally, the congestion threshold data includes a first congestion threshold;

[0170] The step of determining the service assurance strategy for the target service based on pre-set bandwidth proportion threshold data, the service bandwidth data, and the congestion level includes:

[0171] If the congestion data is greater than the first congestion threshold, based on the bandwidth proportion threshold data and the service bandwidth data, it is determined whether to establish a communication resource allocation channel for the target service and whether to provide frame-level QoS guarantee for the target service.

[0172] In one implementation, the first congestion threshold is a pre-set, relatively low congestion threshold. If the congestion data of the base station corresponding to the target service exceeds the first congestion threshold, it can be determined that the service volume carried by the base station corresponding to the target service exceeds its carrying capacity. Further, by comparing the actual bandwidth ratio of the target service with a preset bandwidth ratio threshold, it is determined whether to take the following measures: Establish a communication resource allocation channel (e.g., dedicated load): isolate dedicated network resources for this service to prevent interference from other traffic. Provide frame-level QoS guarantees: set priority marking or retransmission mechanisms for key frames (such as I-frames in video, control commands, etc.).

[0173] In this implementation, when the base station corresponding to the target service is overloaded, a protection strategy for the target service is activated. This ensures the quality of the target service while minimizing the impact on other services.

[0174] Optionally, the congestion threshold data includes multiple congestion thresholds, and the first congestion threshold is the smallest congestion threshold among the multiple congestion thresholds;

[0175] When the congestion data exceeds the first congestion threshold, the process of determining whether to establish a communication resource allocation channel for the target service and whether to provide frame-level QoS guarantees for the target service, based on the bandwidth proportion threshold data and the service bandwidth data, includes:

[0176] If the congestion data is greater than the first congestion threshold, multiple congestion intervals corresponding to different congestion levels are determined based on the multiple congestion thresholds.

[0177] Based on the congestion interval where the congestion data is located, the congestion level of the base station where the target service is located is determined;

[0178] Based on the congestion level of the base station where the target service is located, the bandwidth ratio threshold data, and the service bandwidth data, it is determined whether to establish a communication resource allocation channel for the target service and whether to provide frame-level QoS guarantee for the target service.

[0179] In one implementation, when the congestion data exceeds a first congestion threshold, it indicates that the network is already in a congested state. At this point, the congestion situation is further subdivided based on multiple congestion thresholds, dividing the network into multiple congestion intervals corresponding to different levels of congestion. For example, there may be mild congestion intervals, moderate congestion intervals, and severe congestion intervals, each with its specific threshold range.

[0180] By determining which congestion range the congested data falls within, the degree of congestion faced by the target service can be clearly identified. This allows for a more precise understanding of the impact on the target service under the current network environment.

[0181] The decision to establish a communication resource allocation channel and provide frame-level QoS guarantees is made by comprehensively considering the congestion level of the base station where the target service is located, the bandwidth ratio threshold data, and the service bandwidth data. For example, if the target service is moderately congested and its bandwidth ratio does not exceed the threshold, it may be considered to establish a communication resource allocation channel, such as a dedicated load channel, for it.

[0182] In this implementation, the target service includes XR services. Since XR services typically require the real-time transmission of large amounts of high-definition images, videos, and interactive data, they place stringent demands on network bandwidth and low latency. By precisely determining the congestion level of XR services based on congestion intervals, and combining bandwidth allocation thresholds and service bandwidth data to determine resource allocation and QoS guarantees, necessary communication resources can be prioritized for XR services during network congestion. This provides frame-level QoS guarantees, ensuring smooth operation and reducing issues such as screen stuttering, latency, and dropped frames, thereby providing users with an immersive and high-quality experience.

[0183] Optionally, the plurality of congestion thresholds includes a second congestion threshold and a third congestion threshold, wherein the second congestion threshold is greater than the first congestion threshold, and the third congestion threshold is greater than the second congestion threshold;

[0184] Determining the congestion level of the base station where the target service is located based on the congestion interval where the congestion data is located includes:

[0185] If the congestion data is greater than the first congestion threshold and less than or equal to the second congestion threshold, the congestion level of the base station where the target service is located is determined to be the first congestion level.

[0186] If the congestion data is greater than the second congestion threshold and less than or equal to the third congestion threshold, the congestion level of the base station where the target service is located is determined to be the second congestion level.

[0187] If the congestion data is greater than the third congestion threshold, the congestion level of the base station where the target service is located is determined to be the third congestion level.

[0188] The third level of congestion is greater than the second level of congestion, and the second level of congestion is greater than the first level of congestion.

[0189] In one implementation, for example, the congestion threshold is determined based on the cell PRB occupancy rate. A first congestion threshold is set at a cell PRB occupancy rate of 70%, a second congestion threshold is set at a cell PRB occupancy rate of 80%, and a third congestion threshold is set at a cell PRB occupancy rate of 90%.

[0190] If the cell PRB occupancy rate of the base station corresponding to the target service is greater than 70% and less than or equal to 80%, the congestion level of the base station where the target service is located is determined to be the first level of congestion, which can be understood as mild congestion.

[0191] If the cell PRB occupancy rate of the base station corresponding to the target service is greater than 80% and less than or equal to 90%, the congestion level of the base station where the target service is located is determined to be the second level of congestion, which can be understood as moderate congestion.

[0192] If the cell PRB occupancy rate of the base station corresponding to the target service is greater than 90%, the congestion level of the base station where the target service is located is determined to be the third level of congestion, which can be understood as severe congestion.

[0193] In this implementation, by dividing the network into multiple congestion intervals to determine the congestion level of the base station where the target service is located, the network status can be grasped more precisely, avoiding the crude judgment of simply attributing network congestion to "yes" or "no". This provides a more accurate basis for resource allocation and QoS assurance, and enables more refined network management.

[0194] Optionally, the communication resource allocation channel includes a dedicated transport channel;

[0195] The step of determining whether to establish a communication resource allocation channel for the target service and whether to provide frame-level QoS guarantees for the target service based on the congestion level of the base station where the target service is located, the bandwidth proportion threshold data, and the service bandwidth data includes:

[0196] If the congestion level of the base station where the target service is located is the first congestion level, then the dedicated traffic channel is determined to be established for the target service.

[0197] In one implementation, the bandwidth proportion threshold may include a service bandwidth proportion threshold and a frame bandwidth proportion threshold, and the service bandwidth data includes service bandwidth proportion data and frame bandwidth proportion data. When the congestion level of the base station where the target service is located is at the first congestion level (i.e., mild congestion), regardless of whether the service bandwidth proportion data is greater than or less than the service bandwidth proportion threshold, and regardless of whether the frame bandwidth proportion data is greater than or less than the frame bandwidth proportion threshold, a dedicated bearer channel can be established for the target service.

[0198] In this implementation, if the congestion level of the base station where the target service is located is the first congestion level, it indicates that the network bandwidth resources are sufficient, and establishing a dedicated channel for the target service is beneficial to ensuring the priority of the target service.

[0199] Optionally, the communication resource allocation channel includes a dedicated transport channel;

[0200] The service bandwidth data includes the service bandwidth ratio of the target service and the frame bandwidth ratio of the target service. The service bandwidth ratio is used to indicate the proportion of communication bandwidth occupied by the target service in the total communication bandwidth. The frame bandwidth ratio is used to indicate the proportion of communication bandwidth occupied by each type of frame image data of the target service in the total communication bandwidth. The bandwidth ratio threshold includes the service bandwidth ratio threshold and the frame bandwidth ratio threshold.

[0201] The step of determining whether to establish a communication resource allocation channel for the target service and whether to provide frame-level QoS guarantees for the target service based on the congestion level of the base station where the target service is located, the bandwidth proportion threshold data, and the service bandwidth data includes:

[0202] If the congestion level of the base station where the target service is located is the second congestion level, the service bandwidth ratio is less than the service bandwidth ratio threshold, and the frame bandwidth ratio is less than the frame bandwidth ratio threshold, then it is determined that a dedicated load channel will be established for the target service.

[0203] If the congestion level of the base station where the target service is located is the second congestion level, the service bandwidth ratio is less than the service bandwidth ratio threshold, and the frame bandwidth ratio is greater than or equal to the frame bandwidth ratio threshold, then it is determined that the dedicated load channel is established for the target service, and frame-level QoS guarantee is provided for the target service.

[0204] In one implementation, the bandwidth proportion threshold may include a service bandwidth proportion threshold and a frame bandwidth proportion threshold, and the service bandwidth data includes service bandwidth proportion data and frame bandwidth proportion data.

[0205] When the congestion level of the base station where the target service is located is at the second level of congestion (i.e., moderate congestion), the service bandwidth data is further measured based on the bandwidth proportion threshold:

[0206] If the service bandwidth ratio is less than the service bandwidth ratio threshold and the frame bandwidth ratio is less than the frame bandwidth ratio threshold, it means that the target service and its various frames have little impact on network bandwidth. The priority of the target service can be guaranteed by establishing a dedicated load channel for the target service.

[0207] If the service bandwidth ratio is less than the service bandwidth ratio threshold, and the frame bandwidth ratio is greater than or equal to the frame bandwidth ratio threshold, it indicates that the target service has little overall impact on network bandwidth, but the proportion of unimportant frames is relatively large. In order to ensure the priority of the target service and save bandwidth resources for transmitting other services, a dedicated load channel can be established for the target service, and frame-level QoS guarantees can be provided for the target service.

[0208] In this implementation, the hierarchical strategy accurately matches network status with service requirements, which can both ensure the service priority of the target service and save network resources, thus achieving a balance between quality and network resource utilization.

[0209] Optionally, the communication resource allocation channel includes a default channel:

[0210] The step of determining whether to establish a communication resource allocation channel for the target service and whether to provide frame-level QoS guarantees for the target service based on the congestion level of the base station where the target service is located, the bandwidth proportion threshold data, and the service bandwidth data includes:

[0211] If the congestion level of the base station where the target service is located is the third congestion level, then the default carrier channel is established for the target service, and frame-level QoS guarantee is provided for the target service.

[0212] In one implementation, the bandwidth proportion threshold may include a service bandwidth proportion threshold and a frame bandwidth proportion threshold, and the service bandwidth data includes service bandwidth proportion data and frame bandwidth proportion data.

[0213] When the congestion level of the base station where the target service is located is the third level of congestion (i.e., severe congestion), regardless of whether the service bandwidth ratio data is greater than or less than the service bandwidth ratio threshold, and regardless of whether the frame bandwidth ratio data is greater than or less than the frame bandwidth ratio threshold, it can be determined that a default load channel will be established for the target service, and frame-level QoS guarantees will be provided for the target service.

[0214] Default bearer channel refers to allocating a default bearer channel and corresponding resources for a target service in network resource allocation. Unlike dedicated bearer channels, which provide a completely independent and dedicated bearer for the target service, this allocation method allocates a relatively reasonable share of resources to the target service based on factors such as the overall network resource status and service priority, while ensuring fairness among multiple services.

[0215] In this implementation, when the congestion level of the base station where the target service is located is the third level, it is determined to establish the default load channel for the target service and provide frame-level QoS guarantee for the target service. This is beneficial to optimize the target service on the basis of ensuring fairness among multiple services, while saving network bandwidth usage.

[0216] Optionally, before receiving the first information sent by the second node device, the method further includes:

[0217] A subscription request is sent to the second node device. The subscription request includes data reporting content and data reporting conditions. The data reporting content includes the service bandwidth data of the target service, and the data reporting conditions include at least one of the following:

[0218] When the service bandwidth data reaches a preset threshold, the second node device reports the service bandwidth data to the first node device;

[0219] When a preset reporting period is reached, the second node device reports the service bandwidth data to the first node device, wherein the reported service bandwidth data is the average value of multiple first service bandwidth data within the preset reporting period or the maximum value of the multiple first service bandwidth data.

[0220] In one implementation, the first node device can actively subscribe to certain data of the target service and request the second node device to trigger reporting when specific conditions are met, specifically:

[0221] The data content subscribed to by the first node device may include the service bandwidth data of the target service, and the service bandwidth data may include the service bandwidth ratio and the frame bandwidth ratio of the target service.

[0222] Data reporting conditions may include at least one of the following:

[0223] When the service bandwidth data reaches a preset threshold, the second node device reports the service bandwidth data to the first node device. For example, when the service bandwidth ratio reaches 60%, the second node device reports the service bandwidth ratio to the first node device; when the frame bandwidth ratio reaches 70%, the second node device reports the frame bandwidth ratio to the first node device.

[0224] When a preset reporting period is reached, the second node device reports service bandwidth data to the first node device. The reported service bandwidth data is the average value or the maximum value of multiple first service bandwidth data within the preset reporting period. For example, every 10 minutes, the second node device is required to actively report the service bandwidth ratio and frame bandwidth ratio to the first node device. During these 10 minutes, the second node device collects multiple first service bandwidth ratios and multiple first frame bandwidth ratios. The finally reported service bandwidth ratio is the average value or the maximum value of these multiple first service bandwidth ratios, and the reported frame bandwidth ratio is the average value or the maximum value of these multiple first frame bandwidth ratios.

[0225] In this implementation, the first node device can proactively subscribe to data for specific services based on business needs or network status, thereby ensuring that the latest required data can be quickly obtained in critical scenarios.

[0226] Optionally, when the second node device is a User Plane Function (UPF) and the first node device is a Network Data Analysis Function (NWDAF), the third node device is a Policy Control Function (PCF).

[0227] The first information received from the second node device includes any one of the following:

[0228] Receive the service bandwidth data of the target service and the congestion data of the base station corresponding to the target service sent by the UPF;

[0229] Receive the service bandwidth data of the target service and the congestion data of the base station corresponding to the target service sent by the UPF through the PCF.

[0230] In one implementation, when the second node device is a UPF and the first node device is an NWDAF, the UPF can report service bandwidth data and congestion data to the NWDAF in any of the following ways:

[0231] (1) The UPF directly reports service bandwidth data and congestion data to the NWDAF, enabling the NWDAF to analyze the service bandwidth data and congestion data.

[0232] (2) The UPF reports service bandwidth data and congestion data to the SMF and PCF through the N4 interface, and then the PCF further transmits the service bandwidth data and congestion data to the NWDAF.

[0233] When the first node device is NWDAF and the third node device is PCF, the NWDAF sends the service assurance policy to the PCF.

[0234] In this implementation, the UPF focuses on collecting raw user plane data, the NWDAF is responsible for analysis and decision-making, and the PCF coordinates the distribution of strategies. This conforms to the "modular" design principle of the 3GPP service architecture, improving scalability and maintainability.

[0235] Optionally, the second node device is RAN, and if the first node device is NWDAF, the third node device is PCF;

[0236] The first information received from the second node device includes any one of the following:

[0240] Receive the service bandwidth data of the target service and the congestion data of the base station corresponding to the target service sent by the RAN through the PCF.

[0241] In one implementation, when the second node device is RAN and the first node device is NWDAF, the RAN can report service bandwidth data and congestion data to the NWDAF in any of the following ways:

[0242] (1) The RAN directly reports service bandwidth data and congestion data to the NWDAF;

[0243] (2) The RAN reports service bandwidth data and congestion data to the NWDAF through the Wireless Operation and Maintenance Center (OMC);

[0244] (3) The RAN sends service bandwidth data and congestion data to the UPF based on the uplink accompanying GTP-U extension header, and then the UPF reports the service bandwidth data and congestion data to the NWDAF;

[0245] (4) The RAN reports service bandwidth data and congestion data to the SMF and PCF through the N2 interface, and then the PCF provides the service bandwidth data and congestion data to the NWDAF for further analysis.

[0246] When the first node device is NWDAF and the third node device is PCF, the NWDAF sends the service assurance policy to the PCF.

[0247] In this implementation, the multi-path design takes into account the requirements of real-time performance, analysis depth, and policy closed-loop. While ensuring the QoS of high-reliability services such as XR, it can improve the intelligent management and control capabilities and standardized expansion capabilities of 5G networks.

[0248] Optionally, if the first node device is a UPF, the third node device is a Radio Access Network (RAN).

[0249] The service assurance strategy for sending the target service to the third node device includes any one of the following:

[0250] The Service Assurance Policy for the Target Service is sent to the RAN via the Session Management Function (SMF).

[0251] The service assurance policy for the target service is sent to the RAN via the downlink-as-a-path General Packet Radio Service Tunneling Protocol-User Plane GTP-U extension header.

[0252] In one implementation, when the first node device is a UPF and the third node device is a RAN, the UPF can send the service guarantee policy of the target service to the RAN in any of the following ways:

[0253] (1) The UPF sends the service assurance policy to the SMF and PCF, and then the SMF further sends the service assurance policy to the RAN;

[0254] (2) The UPF sends the service guarantee policy of the target service to the RAN based on the downlink GTP-U extension header to instruct the RAN to update the QoS parameters.

[0255] In this implementation, the strategy transmission method takes into account the requirements of real-time performance, standardization, and hierarchical control, while ensuring the QoS of services such as XR and maximizing the efficiency of 5G network resource scheduling and architectural scalability.

[0256] Optionally, when the second node device is a RAN, receiving the first information sent by the second node device includes:

[0257] The downlink GTP-U extension head receives the service bandwidth data of the target service and the congestion data of the base station corresponding to the target service sent by the RAN.

[0258] In one implementation, when the second node device is a RAN, the first node device can be an NWDAF or a UPF. The first node device can receive service bandwidth data and congestion data sent by the RAN through the downlink accompanying GTP-U extension head.

[0259] In this implementation, the strategy transmission method takes into account the requirements of real-time performance, standardization, and hierarchical control, while ensuring the QoS of services such as XR and maximizing the efficiency of 5G network resource scheduling and architectural scalability.

[0260] This application provides a service assurance method applied to a second node device. See also... Figure 4 , Figure 4 This is a flowchart of the service assurance method provided in the embodiments of this application, such as... Figure 4 As shown, it includes the following steps:

[0261] Step 401: Send first information to the first node device. The first information includes at least one of the service bandwidth data of the target service and the congestion data of the base station corresponding to the target service. The target service includes extended reality (XR) service. The service bandwidth data includes the service bandwidth ratio of the target service and the frame bandwidth ratio of the target service. The service bandwidth ratio is used to indicate the proportion of communication bandwidth occupied by the target service in the total communication bandwidth. The frame bandwidth ratio is used to indicate the proportion of communication bandwidth occupied by each type of frame image data of the target service in the total communication bandwidth.

[0262] Optionally, before sending the first information to the first node device, the method further includes:

[0263] The system receives a subscription request sent by a first node device. The subscription request includes data reporting content and data reporting conditions. The data reporting content includes the service bandwidth data of the target service, and the data reporting conditions include at least one of the following:

[0264] When the service bandwidth data reaches a preset threshold, the second node device reports the service bandwidth data to the first node device;

[0265] When a preset reporting period is reached, the second node device reports the service bandwidth data to the first node device, wherein the reported service bandwidth data is the average value of multiple first service bandwidth data within the preset reporting period or the maximum value of the multiple first service bandwidth data.

[0266] Sending the first information to the first node device includes:

[0267] Based on the subscription request, the first information is sent to the first node device.

[0268] In one implementation, the second node device can trigger data reporting based on the subscription request of the first node device, specifically:

[0269] The data content subscribed to by the first node device may include the service bandwidth data of the target service, and the service bandwidth data may include the service bandwidth ratio and the frame bandwidth ratio of the target service.

[0270] Data reporting conditions may include at least one of the following:

[0271] When the service bandwidth data reaches a preset threshold, the second node device reports the service bandwidth data to the first node device. For example, when the service bandwidth ratio reaches 60%, the second node device reports the service bandwidth ratio to the first node device; when the frame bandwidth ratio reaches 70%, the second node device reports the frame bandwidth ratio to the first node device.

[0272] When a preset reporting period is reached, the second node device reports service bandwidth data to the first node device. The reported service bandwidth data is the average value or the maximum value of multiple first service bandwidth data within the preset reporting period. For example, every 10 minutes, the second node device is required to actively report the service bandwidth ratio and frame bandwidth ratio to the first node device. During these 10 minutes, the second node device collects multiple first service bandwidth ratios and multiple first frame bandwidth ratios. The finally reported service bandwidth ratio is the average value or the maximum value of these multiple first service bandwidth ratios, and the reported frame bandwidth ratio is the average value or the maximum value of these multiple first frame bandwidth ratios.

[0273] In this implementation, the first node device can proactively subscribe to data for specific services based on business needs or network status, thereby ensuring that the latest required data can be quickly obtained in critical scenarios.

[0274] Optionally, sending the first information to the first node device includes:

[0277] When a preset reporting period is reached, the second node device reports the service bandwidth data to the first node device, wherein the reported service bandwidth data is the average value of multiple first service bandwidth data within the preset reporting period or the maximum value of the multiple first service bandwidth data.

[0278] In one implementation, the second node device can also trigger data reporting based on internally configured preset conditions, specifically:

[0279] The data reporting content configured in the preset conditions can include the service bandwidth data of the target service, and the service bandwidth data can include the service bandwidth ratio and the frame bandwidth ratio of the target service.

[0280] The data reporting conditions configured in the preset conditions may include at least one of the following:

[0281] When the service bandwidth data reaches a preset threshold, the second node device reports the service bandwidth data to the first node device. For example, when the service bandwidth ratio reaches 60%, the second node device reports the service bandwidth ratio to the first node device; when the frame bandwidth ratio reaches 70%, the second node device reports the frame bandwidth ratio to the first node device.

[0282] When a preset reporting period is reached, the second node device reports service bandwidth data to the first node device. The reported service bandwidth data is the average value or the maximum value of multiple first service bandwidth data within the preset reporting period. For example, every 10 minutes, the second node device is required to actively report the service bandwidth ratio and frame bandwidth ratio to the first node device. During these 10 minutes, the second node device collects multiple first service bandwidth ratios and multiple first frame bandwidth ratios. The finally reported service bandwidth ratio is the average value or the maximum value of these multiple first service bandwidth ratios, and the reported frame bandwidth ratio is the average value or the maximum value of these multiple first frame bandwidth ratios.

[0283] In this implementation, the second node device actively reports data based on locally configured preset conditions, without relying on external commands, which can reduce latency and improve response speed.
