Description

[0001] This application belongs to the field of communication technology, specifically relating to a QoE measurement method, apparatus, terminal, and network-side equipment. Background Technology

[0002] The main performance indicators of relevant mobile communication systems include peak data rate, latency, and reliability. Next-generation networks (such as 6G) should consider improved user experience quality in addition to these. Ideally, without considering emerging applications with higher performance requirements, the improved performance of next-generation networks (such as 6G) would reduce the probability of performance falling below the sensitivity threshold for user experience quality. However, considering practical factors such as frequency bands, coverage, network load, and environmental conditions (e.g., subways, elevators, high-speed rail, tunnels, underground parking lots, coastal areas), the probability of poor user experience quality is often not significantly reduced. Therefore, achieving better user experience quality requires data collection from actual commercial networks to identify problems, analyze causes, and optimize performance.

The term "base station" is not limited to specific technical terms. It should be noted that the embodiments of this application only use the base station in the NR system as an example for introduction, and do not limit the specific type of base station.

[0075] Core network equipment, also known as core network nodes, core network functions, or core network elements, includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), and Binding Support.

If the name of the core network equipment mentioned in the embodiments of this application changes in subsequent protocol versions (e.g., 6G), it is also within the scope of protection of this application.

[0076] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0077] The QoE process is used by the network to configure the UE to collect QoE data and report it to the network-side equipment. Below are some scenario examples to further illustrate the problems existing in the relevant QoE processes.

[0078] Taking streaming media services as an example, common application scenarios include video playback, music playback, and live streaming. Video playback: For example, watching movies, TV series, and variety shows on online video platforms allows users to start watching shortly after the video loads, unlike traditional download methods where the entire video file must be downloaded before playback. Music playback: Online music platforms allow users to listen to songs in real-time without downloading the entire music file to their device beforehand. Users can switch songs at any time and enjoy a continuous music playback experience. Live streaming: This includes live sports events, news broadcasts, live e-commerce, and game streaming. The broadcaster collects and uploads audio and video data in real-time, while the user receives and plays it in real-time, enabling real-time information transmission and interaction. Among these common application scenarios, the network performance requirements, from highest to lowest, are typically live streaming, video playback, and music playback. Therefore, if QoE is collected uniformly based on streaming services, it may lead to over-collection of QoE measurements for a certain sub-category (for example, music playback is usually smooth and does not require collection), or it may cause data on poor user experience quality in a certain sub-category to be submerged in the overall data of that type (for example, live streaming may experience stuttering due to the inability to pre-cache, and the proportion of poor QoE may be low when analyzing the overall data of streaming services, but if we break it down to the poor QoE quality of live streaming services, then the proportion of poor QoE may be higher).

[0079] Taking special deployment scenarios as an example, the probability of poor user experience quality may be higher in certain scenarios, such as subways, elevators, high-speed trains, tunnels, underground parking lots, and seaside areas. UEs also struggle to obtain real-time and accurate location information, making it difficult to distinguish the actual situation of poor user experience quality (e.g., inside or outside an elevator). For example, in a subway scenario, different UEs may be performing different types of services (e.g., MTSI, streaming service). Even if different UEs are performing the same type of service, the sub-category of that service (IMS voice, IMS video; or WeChat video, WeChat voice, video playback, live streaming) may differ. Some UEs may experience poor user experience quality inside the train car, while others may experience it on the platform outside the car. Therefore, enhanced data collection methods are needed to support network and / or UE problem detection, cause analysis, and optimization.

[0080] The current QoE process suffers from at least one of the following problems, resulting in poor flexibility:

[0081] (1) It supports few service types and does not consider new services under the next generation of networks;

[0082] (2) The service type granularity is relatively coarse. Coarse-grained QoE collection may lead to the collection of QoE of unnecessary sub-services under this service type, consuming more power, or affecting the user experience quality of the sub-services in progress.

[0083] (3) It only supports QoE collection and reporting of terminals, and the data collection is not comprehensive.

[0084] The QoE measurement method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0085] like Figure 2 As shown in the embodiment of this application, a method for measuring Quality of Experience (QoE) is provided, the method comprising:

[0086] Step 201: The terminal receives first information sent by the first network-side device; the first information is used to configure the terminal's QoE measurement.

[0087] Step 202: The terminal performs QoE measurement and sends a QoE report based on the first information.

[0088] In this embodiment, the first network-side device may be a wireless access network node (such as a base station), a core network function node (such as an AMF), or a new service function node, without specific limitations. Among these, the new service function node may potentially be a data plane function (DPF), a sensing function (SF), an artificial intelligence function (AIF), a computing function (CF), an AI control function (AICF), a computing control function (CCF), an external service AI function (NET for AIF), an internal service AI function (such as a network data analytics function (NWDAF)), an external service computing function (NET for Computing function (NETforCF), an internal service computing function (Computing for NET function (CforNETF), an internal service sensing function (Sensing for NET function), or an external service sensing function (NET for Sensing function), etc.

[0089] In at least one embodiment of this application, the first information includes at least one of the following:

[0090] Service type, used to indicate the service type of QoE measurement in network configuration; the service type includes at least one of the following: Extended Reality (XR) service, Sensing service, Artificial Intelligence (AI) service, Computing service, Streaming service, and Multimedia Telephony Service (MTSI) of Internet Protocol Multimedia Subsystem;

[0091] Subtypes of service types; optionally, depending on the services that different terminals or networks are interested in at different times, this subtype can be a type with a smaller range than the service type range;

[0092] QoE type, the QoE type includes at least one of the following: reporting immediately after collection, and storing first and then reporting;

[0093] Reporting type, which indicates the reporting method of QoE reports; the reporting type includes at least one of the following: event-triggered reporting, periodic reporting.

[0094] In one implementation, when the first information only includes a service type, the service type includes at least one of the following: XR service, perception service, AI service, and computing service.

[0095] In this embodiment, the terminal enhances the flexibility of the QoE measurement process by using the first information configured by the network-side device for QoE measurement. This expands the service types supported by QoE measurement, allowing for more accurate analysis of QoE issues related to the expanded service types through more flexible QoE measurement collection. This addresses the problem that related QoE measurements do not support new service types such as sensing or AI.

[0096] Optionally, current voice or video call services include those provided by operators through the IP Multimedia Subsystem (IMS) and those provided by over-the-top (OTT) service providers. Optionally, the aforementioned sensing services may include: sensing services provided by operators; the aforementioned AI services may include: AI services provided by operators; the aforementioned computing services may include: computing services provided by operators.

[0097] In another implementation, the first information is extended to include subtypes under each service type. This allows for more accurate analysis of QoE issues in the extended subtypes through more refined QoE measurement collection. It also avoids the problem that potential QoE issues in a particular service subtype are difficult to detect or analyze due to interference from other QoE measurements under that service type.

[0098] Optionally, the QoE type can be reported immediately after collection, such as ImmediateQoE; or it can be stored first and then reported, such as LoggedQoE.

[0099] For QoE types that store data before reporting, it's important to note that this differs from logged MDT (Logged Minimum Drive Test). Logged MDT primarily considers MDT measurements and reporting by terminals in idle mode. However, logged QoE is geared towards connected terminals. It addresses situations where poor QoE quality might occur due to poor uplink and / or downlink signal quality, or high cell load. In such cases, immediate reporting after data collection could degrade the terminal's experience or reduce spectral efficiency. This is because poor uplink or downlink signal quality may require more spectrum resources to complete QoE measurement and reporting. Alternatively, QoE measurement and reporting may consume resources, reducing the service's overall resources and thus lowering the terminal's experience.

[0100] In one implementation, for the data collection phase, a "store first, report later" approach can be adopted. Optionally, the first network-side device can also configure the maximum length of stored data, such as 128 bytes, through first information or other information. That is, after storing 128 bytes of data, the terminal reports the QoE measurement for this QoE measurement. Alternatively, the maximum length of stored data can be configured through first information or other information, such as 1024 bytes. That is, after storing 1024 bytes of data, the terminal stops storing the QoE measurement for this QoE measurement and reports the QoE measurement when the UE or network is under low load. In other words, "store first, report later" can mean reporting immediately after storing data reaches a certain threshold, or reporting only after storing data reaches a certain threshold and meeting specific conditions, such as when the UE or network is under low load. In another implementation, for the real-time QoE quality optimization phase, a "collect immediately, report later" approach can be adopted, allowing the network time to dynamically adjust its configuration based on the QoE measurement.

[0101] In this embodiment, the QoE type corresponding to the QoE measurement is expanded in the first information, thereby assisting the terminal in achieving more flexible QoE measurement reporting and solving the problem that the existing QoE acquisition process cannot meet the performance requirements of next-generation networks. It is understood that the first network-side device can configure the corresponding QoE type for the terminal according to different performance requirements.

[0102] Optionally, the first information may further include a reporting type, which indicates the reporting method of the QoE report.

[0103] Optionally, the QoE report can be submitted via event-triggered reporting or periodic reporting.

[0104] In this embodiment of the application, the reporting type corresponding to the QoE report of QoE measurement is expanded in the first information, so as to configure the QoE report in a more flexible way and solve the problem that the existing QoE acquisition process cannot meet the performance requirements of the next generation network.

[0105] Optionally, by configuring the QoE type and / or reporting type in the first information, QoE measurements can be filtered, reducing the amount of data in QoE reports and enabling QoE measurements in more granular situations, thereby better supporting QoE collection and experience optimization in scenarios of concern to operators or terminals.

[0106] In at least one embodiment of this application, the first information can be sent to a terminal, a terminal group in the cell, or broadcast to all terminals in the cell via an RRC message.

[0107] Optionally, the first network-side device or other network devices (such as operation and maintenance systems) that interact with the first network-side device can send the first information to a terminal group in the cell or broadcast it to all terminals in the cell according to the scene characteristics covered during cell deployment, thereby collecting experience quality reports reported by multiple terminals in the deployment scenario to meet the performance requirements of the next-generation network.

[0108] In one implementation, the trace collection entity (TCE), operation and maintenance (OAM) system, core network function, radio access network node, or network-side device can select a suitable terminal to send first information based on received requests (such as QoE measurement requests sent by terminals, OAM, core network, application functions, or base station-triggered QoE measurement requests) or its own needs, instructing the corresponding terminal to perform QoE measurement; or the first network-side device can select a suitable terminal to send first information based on terminal capability information (such as QoE measurement capability information reported by the terminal) or terminal authorization information (such as user consent), instructing the corresponding terminal to perform QoE measurement.

[0109] In some embodiments, the subtype of the perception service includes at least one of the following:

[0110] Object detection and tracking services, such as indoor intrusion detection, outdoor intrusion detection (e.g., detection of animals or people intruding into a yard), drone detection, and detection and tracking of people, drones, or animals.

[0111] Environmental monitoring services, such as rainfall monitoring, flood monitoring, and geomorphological change monitoring;

[0112] Motion monitoring services, such as respiratory monitoring and gesture recognition.

[0113] In some embodiments, the subtypes of AI services include at least one of the following:

[0114] AI model inference service;

[0115] AI model training services;

[0116] AI model distribution service, which includes sending complete AI models as well as updating some AI parameters based on previous models, is not specifically limited here;

[0117] Segmentation AI model inference services, including segmentation AI model inference between the terminal and the network, or segmentation AI model inference between the terminal and the application server; for example, segmentation AI image / video recognition, etc.

[0139] In some embodiments, the subtypes of XR services include at least one of the following: Augmented Reality (AR) services; Virtual Reality (VR) services.

[0140] In at least one embodiment of this application, the report type can typically be either periodically triggered or event-triggered. For a report type configured as event-triggered, the terminal is triggered to report measurement results via measurement report trigger configuration information. Specifically, the measurement report trigger configuration information is a measurement report event; the first information further indicates a measurement report event, which is used to trigger the terminal to report a QoE report.

[0141] In one implementation, the first information directly carries the measurement reporting event, or other information in the first information indirectly indicates the measurement reporting event. For example, the measurement reporting event can be indirectly indicated through the service type or subtype.

[0142] In some embodiments, the measurement reporting event includes at least one of the following:

[0143] (1) The QoE measurement value meets the first threshold; for example, the entry condition is that the Mean Opinion Score (MOS) value related to speech quality is less than 3 points, and the exit condition is that the MOS value is greater than 3; or the entry condition is that the initial playback delay is not greater than 1 second, and the exit condition is that the initial playback delay is less than 0.5 seconds; or the entry condition is that the average number of stutters per minute is greater than 1, and the exit condition is that the average number of stutters per minute is greater than 2; or the entry condition is that the perception performance index (such as position accuracy, speed accuracy) is less than the first threshold, and the exit condition is that the aforementioned perception performance index is greater than the first threshold; or the entry condition is that the perception performance index (distance resolution, speed resolution or perception latency) is greater than the first threshold, and the exit condition is that the aforementioned perception performance index is less than the first threshold; or the AI ​​performance index (such as inference accuracy) is not greater than the first threshold; or the computational performance index (such as computational latency) is not less than the first threshold, etc. If a QoE measurement configuration contains multiple service types or multiple service subtypes, the measurement reporting event can be represented in a list format as the threshold that the QoE measurement of each service type or subtype needs to meet, or it can be the average QoE measurement value of multiple service types or multiple service subtypes that meets the first threshold.

[0144] (2) The difference between QoE measurements satisfies the second threshold; optionally, the difference between QoE measurements can be the difference between the average values ​​of QoE measurements over two specified time intervals, or the difference between QoE measurements at two specific time points, or the difference between the maximum and minimum values ​​of QoE measurements within a certain time interval. It is understood that the difference between QoE measurements can reflect or indicate changes in QoE. For example, if the difference between the MOS value in time interval T1 and the MOS value in time interval T1+delta is greater than 2, it indicates a deterioration in speech quality; conversely, if the difference between the MOS value in time interval T1+delta and the MOS value in time interval T1 is greater than 2, it indicates an improvement in speech quality. Similarly, if the difference between the initial playback delay in time interval T1+delta and the initial playback delay in time interval T1 is greater than 1. For example, the difference between QoE measurements represents the change in QoE within delta T1 for the aforementioned perception performance indicators, AI performance indicators, or computing performance indicators. Specific examples such as position accuracy, inference accuracy, or computing latency will not be provided here. The difference between the aforementioned QoE measurements within delta T1 can reflect or indicate the change in QoE within delta T1.

[0145] (3) The fluctuations between QoE measurements meet the third threshold; the fluctuations are used to indicate the stability of QoE; for example, the variance or standard deviation of QoE measurements within the delta T2 time interval is not greater than the third threshold; for example, when the QoE measurements within a certain time interval are X1……Xn and the mean is X', the variance = 1 / n*(X1-X'). 2 +……+(Xn-X') 2 ;

[0146] (4) The time interval of QoE measurement meets the fourth threshold; optionally, the time interval can be obtained by the following parameters: QoE measurement start time and end time; or QoE measurement start time and measurement time length; or QoE measurement end time and measurement time length;

[0147] (5) The location or environment information of the terminal during QoE measurement meets the first condition; for example, the location or environment type of the terminal during measurement is indoor or outdoor, or the location or environment type of the terminal during measurement is inside a subway car or subway platform, or the location type of the terminal during measurement is inside or outside an elevator car, or the location type of the terminal during measurement is inside a high-speed rail car or high-speed rail platform or high-speed rail surrounding area, or the location type of the terminal during measurement is inside or outside an underground parking garage, or the location type of the terminal during measurement is inside or outside a tunnel, or the location type of the terminal during measurement is on a ship or beach or surrounding residential area, etc.

[0148] (6) Event A1 indicates that the service quality of the serving cell is higher than the fifth threshold; for example, Event A1, Serving becomes better than threshold;

[0149] (7) Event A2 indicates that the service quality of the serving cell is lower than the sixth threshold; for example, Event A2, Serving becomes worse than threshold;

[0150] (8) Event A3 indicates that the difference between the service quality of the neighboring cell and the service quality of the serving cell is greater than the seventh threshold; for example, Event A3, Neighbour becomes offset better than SpCell;

[0151] (9) Event A4 indicates that the service quality of the neighboring cell is higher than the eighth threshold; for example, Event A4, Neighbour becomes better than threshold.

[0152] (10) Event A5 indicates that the service quality of the serving cell is lower than the ninth threshold and the service quality of the neighboring cell is higher than the tenth threshold; for example, Event A5, SpCell becomes worse than threshold1 and neighbor becomes better than threshold2.

[0153] (11) Event A6 indicates that the service quality of the neighboring cell is higher than that of the secondary cell; for example, Event A6, Neighbour becomes offset better than SCell;

[0154] (12) Event B1 indicates that the service quality of the inter-system neighbor is greater than the eleventh threshold; for example, Event B1, InterRAT neighbor becomes better than threshold.

[0155] (13) Event B2 indicates that the service quality of the serving cell is lower than the twelfth threshold and the service quality of the inter-system neighboring cells is higher than the thirteenth threshold; for example, Event B2, PCell becomes worse than threshold1 and inter RATneighbour becomes better than threshold2.

[0156] (14) Event I1 indicates that the interference power is higher than the fourteenth threshold; for example, Event I1, Interference becomes higher than threshold.

[0157] (15) Event C1 indicates that the sidelink channel busy ratio is above a threshold; for example, Event C1, The sidelinkchannel busy ratio is above a threshold;

[0158] (16) Event C2 indicates that the sidelink channel busy ratio is below the sixteenth threshold; for example, Event C2, The sidelinkchannel busy ratio is below a threshold;

[0159] (17) Event D1 indicates that the distance between the terminal and the first reference location is greater than the seventeenth threshold; for example, Event D1, Distance between UE and referenceLocation1 is above threshold1 and distance between UE and referenceLocation2 is below threshold2;

[0160] (18) Event D2 indicates that the distance between the UE and the serving cell moving reference location is less than the eighteenth threshold; for example, Event D2, Distance between UE and the serving cell moving reference location is above threshold1 and distance between UE and a moving reference location is below threshold2.

[0161] It should be noted that the thresholds mentioned in the embodiments of this application, such as at least one of the first threshold to the eighteenth threshold, can be determined by network side configuration, terminal implementation, or pre-agreed by protocol, and are not specifically limited here.

[0162] Optionally, the entry conditions mentioned in the embodiments of this application can be understood as the conditions for starting to report QoE reports; the exit conditions can be understood as the conditions for stopping to report QoE reports.

[0163] In at least one embodiment of this application, the QoE report includes at least one of the following:

[0164] The QoE measurement information that satisfies the measurement reporting event;

[0165] The first indication information is used to indicate that the QoE measurement quantity satisfies the measurement reporting event.

[0166] It should be noted that the events mentioned in the embodiments of this application can also be understood as conditions; for example, a measurement reporting event can also be called a measurement reporting condition.

[0167] It should be noted that QoE measurement can also be understood as QoE measurement value, and no specific limitation is made here.

[0168] In one example, entry and exit conditions for an event are defined. For instance, the first event is that the QoE measurement value meets a first threshold. The entry condition is that QoE is less than A, and the exit condition is that QoE is greater than B, where A and B can be the same or different. When the QoE measurement value measured by the terminal is less than A, one possibility is that the terminal reports a QoE measurement value less than A; or the terminal reports a first indication message to indicate that the QoE measurement meets the first event, i.e., the QoE measurement value is cell A. Conversely, if the QoE measurement value measured by the terminal is greater than B, then the terminal neither reports the first indication message nor the QoE measurement value.

[0169] In some embodiments, the QoE measurement information includes at least one of the following:

[0170] A first identifier (such as measurement ID) is used to identify the QoE measurement;

[0171] Service type;

[0172] Subtypes of service types;

[0173] QoE measurements corresponding to the service type and / or the subtype;

[0174] A time stamp is used to identify the time of QoE measurement.

[0175] The downlink signal measurement value corresponding to the timestamp; such as RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), SINR (Signal to Interference plus Noise Ratio) or SNR (Signal to Noise Ratio), etc.

[0176] The acceleration of the terminal;

[0177] Terminal speed;

[0178] The terminal's sensing results; for example, the terminal can sense signals by sending and receiving them on its own, or by receiving sensing signals sent by a base station or other terminals. Sensing results can be obtained in enclosed spaces (such as elevators, high-speed train carriages, etc.) or open spaces larger than N meters (such as high-speed train platforms, subway platforms, etc.).

[0179] The direction of movement of the terminal.

[0180] The QoE measurement includes at least one of the following:

[0181] Average throughput, initial playback latency, or buffering level, etc.;

[0182] Mean opinion score (MOS) related to speech quality;

[0183] Video resolution, frame rate, packet loss rate, jitter, or latency, etc.

[0184] During a video call, the frame rate per second, the stuttering of audio and video, and whether the audio and video are synchronized are all important factors.

[0185] Position accuracy, velocity accuracy, distance resolution, velocity resolution, recognition accuracy, false alarm probability, false alarm rate, and sensing service latency or refresh rate.

[0186] AI model inference accuracy, AI model inference latency, AI model training latency, AI model training accuracy, AI service computing speed, and AI service computing intensity;

[0187] Calculate latency, calculation speed, calculation intensity, and calculation failure rate (or calculation success rate); for example, the calculation failure rate is calculated as the number of failed requests per unit time (e.g., per second, per 5 minutes, per day, etc.) divided by the total number of valid requests per unit time; as another example, the calculation success rate is calculated as the number of successful requests per unit time (e.g., per second, per 5 minutes, per day, etc.) divided by the total number of valid requests per unit time.

[0188] It should be noted that the service type or subtype in the first information is network configuration information, and the service type or subtype of the service type is optional when the terminal sends the QoE report. For example, if the network configures only one service type and / or subtype under a measurement ID using the first information, then the QoE measurement report does not need to include the service type or subtype of the service type. As another example, if the network configures QoE measurements for multiple service subtypes of a service using the first information, the terminal indicates the subtype of the service type corresponding to the QoE measurement by using the subtype of the service type when sending the QoE report.

[0189] In one implementation, the first network-side device receives QoE reports from terminals. By collecting QoE data for new service types or subtypes, the first network-side device (or, through interaction with other network functions) can better analyze whether QoE issues exist. Configuring the reporting of trigger events allows for more precise collection of QoE measurements for service types that meet the trigger event. Compared to reporting all QoE, this reduces the amount of data and provides more flexible support for QoE collection in special scenarios where operators or terminals may experience poor quality of life (such as location type or signal quality characteristics). For example, configuring the reporting of trigger events can collect QoE data in subway cars where the average number of video stutters is greater than 1 and the serving cell's RSRP is greater than a threshold.

[0190] In at least one embodiment of this application, the method further includes:

[0191] The terminal sends QoE measurement capability information to the first network-side device; the QoE measurement capability information includes at least one of the following:

[0192] QoE measurement indication is used to indicate whether the terminal supports QoE measurement;

[0193] The terminal supports the following service types for QoE measurement:

[0194] The terminal supports subtypes of the QoE measurement service types.

[0195] Since QoE involves the application processor (AP) on the terminal, it typically requires the cooperation of the terminal modem, operating system, and other components to perform QoE measurement and reporting. Therefore, terminal-reported QoE measurement capability information is more helpful for the network to select appropriate terminals for QoE collection.

[0196] In some embodiments of this application, the QoE measurement can be triggered by a first network-side device through first information, or it can be triggered by a terminal.

[0197] The terminal-triggered QoE measurement process helps the terminal trigger network-side devices to collect QoE measurements of that terminal. Optionally, the network-side devices can perform QoE quality analysis on the terminal and optimize its QoE quality through configuration. The advantage of this approach is that the terminal can initiate QoE measurements on demand based on the experience quality of a specific service type or subtype, rather than passively receiving QoE measurement configurations from the network-side devices. Terminal-triggered QoE measurement collection is more effective in identifying and addressing poor QoE quality issues at the terminal, enabling optimization tailored to that specific terminal. This embodiment can effectively identify and resolve issues caused by differences in the experience quality of various terminals.

[0198] In one implementation, the method further includes:

[0199] The terminal sends a first QoE measurement request to the first network-side device, the first QoE measurement request being used to request QoE measurement;

[0200] The terminal receives a first QoE measurement response sent by the first network-side device, the first QoE measurement response being used to indicate acceptance of the first QoE measurement request.

[0201] In another implementation, the method further includes:

[0202] The terminal sends a second QoE measurement request to the first network-side device, the second QoE measurement request being used to request a QoE measurement; correspondingly, step 201 includes:

[0203] The terminal receives a second QoE measurement response sent by the first network-side device. The second QoE measurement response is used to indicate acceptance of the second QoE measurement request, and the second QoE measurement response also carries the first information.

[0204] In this embodiment, the terminal sends a QoE measurement request to the first network device. Since different terminals use different services at different times with varying frequencies, and different users have different levels of concern regarding the QoE of different services, and different users have different QoE requirements for the same service (e.g., some users prioritize high definition, while others prioritize smoothness), the terminal determines which QoE measurement request to send based on its needs (a first QoE measurement request and / or a second QoE measurement request). This embodiment supports terminal-triggered QoE measurements, which facilitates QoE collection and optimization for a specific terminal.

[0205] As an optional embodiment, a first network-side device receives a QoE measurement request sent by a terminal. The first network-side device (or the first network-side device interacting with other network functions) determines whether to accept the QoE measurement request. For example, if the terminal's QoE measurement helps the network discover, analyze, or resolve problems, and the network can schedule appropriate resources to satisfy the QoE measurement request, then the QoE measurement request is accepted. The first network-side device sends a QoE measurement response to the terminal, the QoE measurement response including at least "accept" or "reject," indicating whether the corresponding QoE measurement request is accepted or rejected. Optionally, if the QoE request is accepted, the QoE measurement response may further include the aforementioned first information; or, the first information may be a new message independent of the QoE measurement response, for example, the first network-side device sends the first information to the terminal after sending the QoE measurement response or simultaneously with it. Optionally, if the QoE request is rejected, the QoE measurement response may further include a rejection reason, such as insufficient resources or lack of interest.

[0206] In some embodiments, the first QoE measurement request and / or the second QoE measurement request includes at least one of the following:

[0207] Service type indicates the type of QoE measurement requested by the terminal;

[0208] Subtype of service type, indicating the subtype of the above service type;

[0209] QoE type, indicating the type of QoE measurement requested by the terminal;

[0210] Reporting type indicates the reporting type of the QoE report requested by the terminal for the QoE measurement;

[0211] Measurement reporting event, indicating the measurement reporting event of the QoE measurement requested by the terminal.

[0212] It should be noted that the definitions of the above service types, subtypes, QoE types, reporting types, and measurement reporting events are consistent with those in the above embodiments, and will not be repeated here.

[0213] Optionally, after receiving the QoE measurement response from the first network-side device, if the first network-side device accepts the QoE measurement request, then the terminal performs QoE measurement based on the first information and sends a QoE report.

[0214] In some embodiments, after the first network-side device receives the QoE report sent by the terminal:

[0215] Optionally, the first network-side device (or the first network-side device interacting with other network functions) determines whether to continue collecting QoE based on the received QoE report. If it is necessary to continue collecting QoE, the first network-side device can select an appropriate terminal to continue collecting QoE by using the procedure of triggering QoE measurement by the network-side device.

[0216] Optionally, the first network-side device (or the first network-side device interacting with other network functions) discovers or analyzes the experience quality issues of the terminal that triggered QoE collection, and sends a configuration message to the terminal to optimize the experience quality. The configuration message may include switching configuration information, uplink resource configuration, downlink resource configuration, QoS parameter configuration, etc. For example, for terminals in a subway scenario, the ultimate goal is to enable terminals inside the carriage to access cells covering the track area, and terminals on the platform to access cells covering the platform area.

[0217] In summary, in this embodiment, the first information configured by the terminal for QoE measurement through the network-side device enhances the flexibility of the QoE measurement process. Specifically, it expands the service types supported by QoE measurement, or expands the subtypes under each service type, or expands the QoE type corresponding to QoE measurement, or expands the reporting type corresponding to the QoE report of QoE measurement. This allows for more flexible or refined QoE measurement collection, enabling more accurate analysis of QoE issues and addressing the problem that existing QoE collection processes cannot meet the performance requirements of next-generation networks.

[0218] like Figure 3 As shown in the embodiments of this application, a QoE measurement method is also provided, the method comprising:

[0219] Step 301: The first network-side device sends first information to the terminal; the first information is used to configure the terminal's QoE measurement.

[0220] Step 302: The first network-side device receives a QoE report sent by the terminal after performing QoE measurement based on the first information.

[0221] In this embodiment, the first network-side device may be a wireless access network node (such as a base station), a core network function node (such as an AMF), or a new service function node, without specific limitations. Among these, the new service function node may potentially be a data plane function (DPF), a sensing function (SF), an artificial intelligence function (AIF), a computing function (CF), an AI control function (AICF), a computing control function (CCF), an external service AI function (NET for AIF), an internal service AI function (such as a network data analytics function (NWDAF)), an external service computing function (NET for Computing function (NETforCF), an internal service computing function (Computing for NET function (CforNETF), an internal service sensing function (Sensing for NET function), or an external service sensing function (NET for Sensing function), etc.

[0222] In at least one embodiment of this application, the first information includes at least one of the following:

[0223] Service type, used to indicate the service type of QoE measurement in network configuration; the service type includes at least one of the following: Extended Reality (XR) service, Sensing service, Artificial Intelligence (AI) service, Computing service, Streaming service, and Multimedia Telephony Service (MTSI) of Internet Protocol Multimedia Subsystem;

[0224] Subtypes of service types; optionally, depending on the services that different terminals or networks are interested in, the subtype can be a type smaller than the service type range;

[0225] QoE type, the QoE type includes at least one of the following: reporting immediately after collection, and storing first and then reporting;

[0226] Reporting type, which indicates the reporting method of QoE reports; the reporting type includes at least one of the following: event-triggered reporting, periodic reporting.

[0227] In one implementation, the terminal enhances the flexibility of the QoE measurement process by using the first information configured for QoE measurement by the network-side device. This expands the service types supported by QoE measurement, allowing for more accurate analysis of QoE issues related to the expanded service types through more flexible QoE measurement collection. This addresses the current problem that QoE measurement does not support new service types such as sensing or AI.

[0228] In another implementation, the first information is extended to include subtypes under each service type. This allows for more accurate analysis of QoE issues in the extended subtypes through more refined QoE measurement collection. It also avoids the problem that potential QoE issues in a particular service subtype are difficult to detect or analyze due to interference from other QoE measurements under that service type.

[0229] Optionally, in this embodiment of the application, the QoE type corresponding to the QoE measurement is extended in the first information, thereby assisting the terminal to achieve more flexible QoE measurement reporting, which can solve the problem that the existing QoE acquisition process cannot meet the performance requirements of the next-generation network.

[0230] Optionally, in this embodiment of the application, the reporting type corresponding to the QoE report of the QoE measurement is expanded in the first information, so as to configure the QoE report in a more flexible manner and solve the problem that the existing QoE acquisition process cannot meet the performance requirements of the next generation network.

[0231] Optionally, the QoE type can be reported immediately after collection, such as ImmediateQoE; or it can be stored first and then reported, such as LoggedQoE.

[0232] Optionally, the first network-side device or other network devices (such as operation and maintenance systems) that interact with the first network-side device can send the first information to a terminal group in the cell or broadcast it to all terminals in the cell according to the scene characteristics covered during cell deployment, thereby collecting experience quality reports reported by multiple terminals in the deployment scenario to meet the performance requirements of the next-generation network.

[0233] In one implementation, the trace collection entity (TCE), operation and maintenance (OAM) system, core network function, or radio access network node can select a suitable terminal to send first information based on the received request or its own needs, instructing the corresponding terminal to perform QoE measurement; or the first network-side device can select a suitable terminal to send first information based on terminal capability information (such as QoE measurement capability information reported by the terminal) or terminal authorization information (such as user consent), instructing the corresponding terminal to perform QoE measurement.

[0234] In at least one embodiment of this application, the report type can typically be either periodically triggered or event-triggered. For a report type configured as event-triggered, the terminal is triggered to report measurement results via measurement report trigger configuration information. Specifically, the measurement report trigger configuration information is a measurement report event; the first information further indicates a measurement report event, which is used to trigger the terminal to report a QoE report.

[0235] In one implementation, the first information directly carries the measurement reporting event, or other information in the first information indirectly indicates the measurement reporting event. For example, the measurement reporting event can be indirectly indicated through the service type or subtype.

[0236] In some embodiments, the measurement reporting event includes at least one of the following:

[0237] (1) The QoE measurement value meets the first threshold;

[0238] (2) The difference between the QoE measurements satisfies the second threshold;

[0239] (3) The fluctuations between QoE measurements satisfy the third threshold;

[0245] (9) Event A4 indicates that the service quality of the neighboring cell is higher than the eighth threshold;

[0246] (10) A5 event indicates that the service quality of the serving cell is lower than the ninth threshold and the service quality of the neighboring cells is higher than the tenth threshold.

[0247] (11) Incident A6 indicates that the service quality of the neighboring cell is higher than that of the auxiliary cell;

[0248] (12) B1 event, indicating that the service quality of neighboring cells in different systems is greater than the eleventh threshold;

[0278] Calculate latency, calculation speed, calculation intensity, and calculation failure rate (or calculation success rate); for example, the calculation failure rate is calculated as the number of failed requests per unit time (e.g., per second, per 5 minutes, per day, etc.) divided by the total number of valid requests per unit time; as another example, the calculation success rate is calculated as the number of successful requests per unit time (e.g., per second, per 5 minutes, per day, etc.) divided by the total number of valid requests per unit time.

[0279] It should be noted that the service type or subtype in the first information is network configuration information, and is optional when reported by the terminal. For example, when the network configures multiple service subtypes for QoE measurement under a measurement ID, the terminal will include the service type subtype when reporting the QoE report.

[0280] In one implementation, the first network-side device receives QoE reports from terminals. By collecting QoE data for new service types or subtypes, the first network-side device (or, through interaction with other network functions) can better analyze whether QoE issues exist. Configuring the reporting of trigger events allows for more precise collection of QoE measurements for service types that meet the trigger event. Compared to reporting all QoE, this reduces the amount of data and provides more flexible support for QoE collection in special scenarios where operators or terminals may experience poor quality of life (such as location type or signal quality characteristics). For example, configuring the reporting of trigger events can collect QoE data in subway cars where the average number of video stutters is greater than 1 and the serving cell's RSRP is greater than a threshold.

[0281] In at least one embodiment of this application, the method further includes:

[0282] The first network-side device receives QoE measurement capability information sent by the terminal; the QoE measurement capability information includes at least one of the following:

[0283] QoE measurement indication is used to indicate whether the terminal supports QoE measurement;

[0284] The terminal supports the following service types for QoE measurement:

[0285] The terminal supports subtypes of the service types for QoE measurement;

[0286] The first network-side device determines the first information based on the obtained QoE measurement capability information.

[0287] Since QoE involves the application processor (AP) on the terminal, it typically requires the cooperation of the terminal modem, operating system, and other components to perform QoE measurement and reporting. Therefore, terminal-reported QoE measurement capability information is more helpful for the network to select appropriate terminals for QoE collection.

[0288] In some embodiments of this application, the QoE measurement can be triggered by a first network-side device through first information, or it can be triggered by a terminal.

[0289] The terminal-triggered QoE measurement process helps the terminal trigger the network to collect QoE measurements for that terminal. Optionally, the network can perform QoE quality analysis on the terminal and optimize its QoE quality through configuration. The advantage of this approach is that the terminal can initiate QoE measurements on demand based on the experience quality of a specific service type or subtype, rather than passively receiving QoE measurement configurations from the network. Terminal-triggered QoE measurement collection is more effective in identifying and addressing poor QoE quality issues and their causes, enabling optimization tailored to that terminal. This embodiment can effectively identify and resolve issues caused by differences in the experience quality of various terminals.

[0290] In one implementation, the method further includes:

[0291] The first network-side device receives a first QoE measurement request sent by the terminal, the first QoE measurement request being used to request QoE measurement;

[0292] The first network-side device sends a first QoE measurement response to the terminal based on the first QoE measurement request. The first QoE measurement response is used to indicate acceptance of the first QoE measurement request.

[0293] In another implementation, the method further includes:

[0294] The first network-side device receives a second QoE measurement request sent by the terminal, the second QoE measurement request being used to request QoE measurement; correspondingly, step 301 includes:

[0295] The first network-side device sends a second QoE measurement response to the terminal according to the second QoE measurement request. The second QoE measurement response is used to indicate acceptance of the second QoE measurement request, and the second QoE measurement response also carries the first information.

[0296] In this embodiment, the terminal sends a QoE measurement request to the first network device. Since different terminals use different services at different times with varying frequencies, different users have different levels of concern regarding the QoE of different services, and different users have different QoE requirements for the same service (e.g., some users prioritize high definition, while others prioritize smoothness). Therefore, the terminal determines which QoE measurement request to send based on its needs (a first QoE measurement request and / or a second QoE measurement request).

[0297] As an optional embodiment, a first network-side device receives a QoE measurement request sent by a terminal. The first network-side device (or the first network-side device interacting with other network functions) determines whether to accept the QoE measurement request. For example, if the terminal's QoE measurement helps the network discover, analyze, or resolve problems, and the network can schedule appropriate resources to satisfy the QoE measurement request, then the QoE measurement request is accepted. The first network-side device sends a QoE measurement response to the terminal, the QoE measurement response including at least an acceptance or rejection statement to indicate acceptance or rejection of the corresponding QoE measurement request. Optionally, if the QoE request is accepted, the QoE measurement response may further include the aforementioned first information; or, the first information may be a new message independent of the QoE measurement response, for example, the first network-side device sends the first information to the terminal after sending the QoE measurement response or simultaneously with it. Optionally, if the QoE request is rejected, the QoE measurement response may further include a rejection reason, such as insufficient resources or lack of interest.

[0298] In some embodiments, the first QoE measurement request and / or the second QoE measurement request includes at least one of the following:

[0299] Service type indicates the type of QoE measurement requested by the terminal;

[0300] Subtype of service type, indicating the subtype of the above service type;

[0301] QoE type, indicating the type of QoE measurement requested by the terminal;

[0302] Reporting type indicates the reporting type of the QoE report requested by the terminal for the QoE measurement;

[0303] Measurement reporting event, indicating the measurement reporting event of the QoE measurement requested by the terminal.

[0304] It should be noted that the definitions of the above service types, subtypes, QoE types, reporting types, and measurement reporting events are consistent with those in the above embodiments, and will not be repeated here.

[0305] Optionally, after the terminal receives the QoE measurement response from the first network-side device, if the first network-side device accepts the QoE measurement request, then the terminal performs a QoE measurement based on the first information and sends a QoE report. After the first network-side device receives the QoE report from the terminal:

[0306] Optionally, the first network-side device (or the first network-side device interacting with other network functions) determines whether to continue collecting QoE based on the received QoE report. If it is necessary to continue collecting QoE, the first network side can select a suitable terminal to continue collecting QoE using a network-triggered QoE measurement procedure.

[0307] Optionally, the first network-side device (or the first network-side device interacting with other network functions) discovers or analyzes the experience quality issues of the terminal that triggered QoE collection, and sends a configuration message to the terminal to optimize the experience quality. The configuration message may include switching configuration information, uplink resource configuration, downlink resource configuration, QoS parameter configuration, etc. For example, for terminals in a subway scenario, the ultimate goal is to enable terminals inside the carriage to access cells covering the track area, and terminals on the platform to access cells covering the platform area.

[0308] In summary, in this embodiment, the network-side device configures the terminal with first information for QoE measurement, enhancing the flexibility of the QoE measurement process. Specifically, it expands the service types supported by QoE measurement, or expands the subtypes under each service type, or expands the QoE type corresponding to QoE measurement, or expands the reporting type corresponding to the QoE report of QoE measurement. This allows for more flexible or refined QoE measurement collection, enabling more accurate analysis of QoE issues and addressing the problem that existing QoE collection processes cannot meet the performance requirements of next-generation networks.

[0309] like Figure 4 As shown in the embodiments of this application, a QoE measurement method is also provided, the method comprising:

[0310] Step 401: The second network-side device receives an auxiliary measurement request sent by the terminal. The auxiliary measurement request is used to request the second network-side device to measure the QoE of the terminal.

[0311] Step 402: The second network-side device measures the QoE of the terminal according to the auxiliary measurement request and obtains a QoE report.

[0312] In this embodiment, the second network-side device can be a wireless access network node (such as a base station), a core network function node (such as an AMF), or a new service function node, without specific limitations. Among these, the new service function node may potentially be a data plane function (DPF), a sensing function (SF), an artificial intelligence function (AIF), a computing function (CF), an AI control function (AICF), a computing control function (CCF), an external service AI function (NET for AIF), an internal service AI function (such as a network data analytics function (NWDAF)), an external service computing function (NET for Computing function (NETforCF), an internal service computing function (Computing for NET function (CforNETF), an internal service sensing function (Sensing for NET function), or an external service sensing function (NET for Sensing function), etc.

[0313] This application embodiment assumes that the network can obtain the terminal's QoE, and the terminal requests the network's assistance in collecting QoE measurements. As mentioned earlier, QoE measurement and reporting by the terminal typically requires the collaboration of the terminal's modem, operating system, and application functions. For services provided by operators, such as the aforementioned multimedia telephony service of the Internet Protocol Multimedia Subsystem, operator-provided sensing services, AI services, or computing services, the network can obtain the terminal's QoE. Simultaneously, some OTT application servers also cooperate with operators, so the network may also obtain the QoE of terminals providing these cooperative services. Furthermore, network-assisted QoE measurement and collection by the terminal helps the network monitor and optimize the user experience for that terminal and can save on the transmission overhead of QoE reports.

[0314] In some embodiments of this application, the auxiliary measurement request includes at least one of the following:

[0315] Service type, used to indicate the type of auxiliary measurement service requested by the terminal; the service type includes at least one of the following: extended reality XR service, sensing service, artificial intelligence AI service, computing service, streaming media service, and multimedia telephony service of Internet Protocol Multimedia Subsystem;

[0316] Subtypes of service types; optionally, depending on the services that different terminals or networks are interested in, the subtype can be a type smaller than the service type range;

[0317] QoE type, the QoE type includes at least one of the following: immediate transmission after acquisition, storage before transmission;

[0318] The sending type indicates the method of sending QoE reports; the sending type includes at least one of the following: no report, event-triggered sending, and periodic sending;

[0319] A measurement target list is used to indicate the cells for which the QoE measurement of the terminal is performed; the cells include the serving cell and / or neighboring cells; optionally, the cells for which the QoE measurement of the terminal is performed can be the terminal's serving cell by default;

[0320] Measure the sent event.

[0321] Optionally, carrying the service type and / or subtype in the auxiliary measurement request enables network-side devices to collect QoE for new services or more accurate service subtypes. This supports 6G sensing services, AI services, or computing services, and also solves the problem that the QoE of a service subtype is hidden in all the data of the service type to which the subtype belongs, making it difficult to discover the problem of poor experience quality and analyze the cause.

[0322] Optionally, QoE measurements can be filtered by configuring QoE type and / or transmission type, reducing the amount of data in QoE reports and enabling QoE measurements in more granular situations, thereby better supporting QoE collection and experience optimization in scenarios of concern to operators or terminals.

[0323] This application's embodiments support terminal-triggered QoE measurement, which helps in QoE collection and optimization for a specific terminal.

[0324] This application embodiment supports the terminal requesting the network-side device to measure the terminal's QoE. On the one hand, this allows the terminal to obtain QoE information from the network-side device. On the other hand, the network-side device can also perform network configuration based on the terminal's QoE measurement to achieve rapid QoE optimization and loop closure, saving the transmission resources of QoE reports.

[0325] Optionally, the QoE type can be sent immediately after acquisition, such as Immediate QoE; or it can be stored first and then sent, such as Logged QoE.

[0326] In one implementation, during the data collection phase, a "store first, then send" approach can be used. This reduces the number of times network-side devices send QoE reports, lowering communication overhead. In another implementation, during the real-time QoE quality optimization phase, data can be collected and sent immediately, ensuring the network sends QoE reports promptly.

[0327] Alternatively, voice or video call services are currently provided by both operators through the IP Multimedia Subsystem (IMS) and by over-the-top (OTT) service providers.

[0328] Optionally, the aforementioned sensing services may include: sensing services provided by the operator; the aforementioned AI services may include: AI services provided by the operator; and the aforementioned computing services may include: computing services provided by the operator.

[0329] Optionally, for transmission types configured as event-triggered, the measurement transmission trigger configuration triggers the second network-side device to report measurement results. For transmission types configured not to report, the measurement transmission trigger configuration can be called a QoE optimization trigger configuration, or a trigger configuration that instructs the terminal to request QoE optimization. Typically, the measurement transmission trigger configuration includes a measurement transmission event.

[0330] It should be noted that the definitions of the subtypes of the above service types are the same as those in the above embodiments, and will not be repeated here.

[0331] In some embodiments, the measurement transmission event includes at least one of the following:

[0332] (1) The QoE measurement value of the serving cell meets the nineteenth threshold; for example, the entry condition is that the MOS (Mean Opinion Score) value related to voice quality is less than 3 points, and the exit condition is that the MOS value is greater than 3; or the entry condition is that the initial playback delay is not greater than 1 second, and the exit condition is that the initial playback delay is less than 0.5 seconds; or the entry condition is that the average number of stutters per minute is greater than 1, and the exit condition is that the average number of stutters per minute is greater than 2; or the entry condition is that the perception performance index (such as position accuracy, speed accuracy) is less than the fifth threshold, and the exit condition is that the aforementioned perception performance index is greater than the fifth threshold; or the entry condition is that the perception performance index (distance resolution, speed resolution or perception latency) is greater than the fifth threshold, and the exit condition is that the aforementioned perception performance index is less than the fifth threshold; or the AI ​​performance index (such as inference accuracy) is not greater than the fifth threshold; or the computational performance index (such as computational latency) is not less than the fifth threshold, etc. If a QoE measurement configuration includes multiple service types or multiple service subtypes, the measurement sending event can be represented in a list format as the threshold that the QoE measurement of each service type or subtype needs to meet, or it can be the average QoE measurement value of multiple service types or multiple service subtypes that meets the fifth threshold.

[0333] (2) The difference between the QoE measurements of the serving cell meets the twentieth threshold; optionally, the difference between the QoE measurements can be the difference between the average values ​​of QoE measurements over two specified time intervals, or the difference between the QoE measurements at two specific time points, or the difference between the maximum and minimum QoE measurements within a certain time interval. It is understood that the difference between QoE measurements can reflect or indicate changes in QoE. For example, if the difference between the MOS value in time interval T1 and the MOS value in time interval T1+delta is greater than 2, it indicates a deterioration in voice quality. As another example, if the difference between the MOS value in time interval T1+delta and the MOS value in time interval T1 is greater than 2, it indicates an improvement in voice quality. As yet another example, if the difference between the initial playback delay in time interval T1+delta and the initial playback delay in time interval T1 is greater than 1. For example, the difference between QoE measurements represents the change in QoE within delta T1 for the aforementioned perception performance indicators, AI performance indicators, or computing performance indicators. Specific examples such as position accuracy, inference accuracy, or computing latency will not be provided here. The difference between the aforementioned QoE measurements within delta T1 can reflect or indicate the change in QoE within delta T1.

[0334] (3) The fluctuations between the QoE measurements of the serving cell meet the twenty-first threshold; the fluctuations are used to indicate the stability of QoE; the fluctuations are used to indicate the stability of QoE; for example, the variance or standard deviation of the QoE measurements within the time interval delta T2 is not greater than the third threshold; for example, when the QoE measurements within a certain time interval are X1……Xn, and the mean is X', the variance = 1 / n*(X1-X'). 2 +……+(Xn-X') 2 ;

[0335] (4) The predicted QoE value of the neighboring cell meets the twenty-second threshold. When the network has the QoE prediction capability, it can assist the terminal in predicting the QoE measurement of the neighboring cell.

[0336] (5) The QoE quality of the serving cell is less than the twenty-third threshold, and the predicted QoE value of the neighboring cell meets the twenty-fourth threshold.

[0337] (6) The difference between the predicted QoE value of the neighboring cell and the measured QoE value of the serving cell satisfies the 25th threshold, and the predicted QoE value of the neighboring cell is greater than the measured QoE value of the serving cell.

[0338] (7) The time interval of QoE measurement satisfies the twenty-sixth threshold; optionally, the time interval can be obtained by the following parameters: QoE measurement start time and end time; or QoE measurement start time and measurement duration; or QoE measurement end time and measurement duration.

[0339] (8) The location information or environmental information of the terminal during QoE measurement meets the first condition; for example, the location type or environmental type of the terminal during measurement is indoor or outdoor, or the location type or environmental type of the terminal during measurement is inside a subway car or subway platform, or the location type of the terminal during measurement is inside or outside an elevator car, or the location type of the terminal during measurement is inside a high-speed rail car or high-speed rail platform or high-speed rail surrounding area, or the location type of the terminal during measurement is inside or outside an underground parking garage, or the location type of the terminal during measurement is inside or outside a tunnel, or the location type of the terminal during measurement is on a ship or beach or surrounding residential area, etc.

[0340] (9) Event A1 indicates that the service quality of the serving cell is higher than the fifth threshold; for example, Event A1, Serving becomes better than threshold;

[0341] (10) Event A2 indicates that the service quality of the serving cell is lower than the sixth threshold; for example, Event A2, Serving becomes worse than threshold;

[0342] (11) Event A3 indicates that the difference between the service quality of the neighboring cell and the service quality of the serving cell is greater than the seventh threshold; for example, Event A3, Neighbour becomes offset better than SpCell;

[0343] (12) Event A4 indicates that the service quality of the neighboring cell is higher than the eighth threshold; e.g., Event A4, Neighbour becomes better than threshold);

[0344] (13) Event A5 indicates that the service quality of the serving cell is lower than the ninth threshold and the service quality of the neighboring cell is higher than the tenth threshold; for example, Event A5, SpCell becomes worse than threshold1 and neighbor becomes better than threshold2.

[0345] (14) Event A6 indicates that the service quality of the neighboring cell is higher than that of the secondary cell; for example, Event A6, Neighbour becomes offset better than SCell;

[0346] (15) Event B1 indicates that the service quality of the inter-system neighbor is greater than the eleventh threshold; for example, Event B1, InterRAT neighbor becomes better than threshold.

[0347] (16) Event B2 indicates that the service quality of the serving cell is lower than the twelfth threshold and the service quality of the inter-system neighboring cells is higher than the thirteenth threshold; for example, Event B2, PCell becomes worse than threshold1 and inter RATneighbour becomes better than threshold2.

[0348] (17) Event I1 indicates that the interference power is higher than the fourteenth threshold; for example, Event I1, Interference becomes higher than threshold.

[0349] (18) Event C1 indicates that the sidelink channel busy ratio is above the fifteenth threshold; for example, Event C1, The sidelinkchannel busy ratio is above a threshold;

[0350] (19) Event C2 indicates that the sidelink channel busy ratio is below the sixteenth threshold; for example, Event C2, The sidelinkchannel busy ratio is below a threshold;

[0351] (20) Event D1 indicates that the distance between the UE and referenceLocation1 is above threshold1 and the distance between the UE and referenceLocation2 is below threshold2.

[0352] (21) Event D2 indicates that the distance between the UE and the serving cell moving reference location is less than the eighteenth threshold; for example, Event D2, Distance between UE and the serving cell moving reference location is above threshold1 and distance between UE and a moving reference location is below threshold2.

[0353] Optionally, the aforementioned measurement transmission event may further include: QoE problem delimitation, also known as poor experience quality cause analysis. QoE problem delimitation refers to the ability of the network-side device to delimit the poor experience quality when it discovers a QoE problem after performing QoE measurements. An example of QoE problem delimitation includes at least one of the following: terminal, network-side device, application server, and environment, respectively indicating that the poor experience quality is caused by the terminal, network, application server, or environment. It is necessary to support situations where the service is provided by an operator's network, such as when the operator provides sensing services or AI services. If the problem is with the sensing function or AI node, then the QoE problem delimitation is the network. Alternatively, the network-side device can be further divided into two categories: network transmission and network service QoE problem delimitation. Another example includes the terminal, network-side device, or others. Since the terminal is more concerned with whether the problem is its own, the latter two can basically meet this requirement. Optionally, the aforementioned measurement transmission event may also include the confidence level of the QoE problem delimitation. Since the network side may also be analyzing based on the data collected at the moment, the delimitation of the QoE problem needs to be explained with confidence level.

[0354] In at least one embodiment of this application, the method further includes:

[0355] The second network-side device sends an auxiliary measurement response to the terminal, the auxiliary measurement response being used to indicate whether to accept or reject the auxiliary measurement request.

[0356] In some embodiments, the second network-side device receives a QoE measurement request from the terminal. The second network-side device (or interacts with other network functions) determines whether to accept the QoE measurement request. The second network-side device sends a QoE measurement response to the terminal, the QoE measurement response including at least an acceptance or rejection statement to indicate whether the QoE measurement request is accepted or rejected. Optionally, if the QoE request is rejected, the QoE measurement response may further include a reason for rejection, such as insufficient resources.

[0357] It should be noted that the auxiliary measurement request mentioned in the embodiments of this application can also be referred to as a network-assisted auxiliary measurement request, and the auxiliary measurement response can also be referred to as a network-assisted QoE measurement response.

[0358] In at least one embodiment of this application, the method further includes:

[0359] The second network-side device sends the QoE report to the terminal.

[0360] If the second network-side device accepts a network-assisted QoE measurement request, and the transmission type is periodic or event-triggered, then the terminal receives the QoE report sent by the second network-side device. The QoE report may contain QoE reports from multiple cells.

[0361] Optionally, the QoE report includes at least one of the following:

[0362] The QoE measurement information that satisfies the measurement transmission event;

[0363] The second indication information is used to indicate that the QoE measurement quantity satisfies the measurement transmission event.

[0364] In some embodiments, the QoE measurement information includes at least one of the following:

[0365] A first identifier (such as measurement ID) is used to identify the QoE measurement;

[0366] Service type;

[0367] Subtypes of service types;

[0368] QoE measurements corresponding to the service type and / or the subtype;

[0369] A time stamp is used to identify the time of a QoE measurement.

[0370] The uplink signal measurement value corresponding to the timestamp; such as RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), SINR (Signal to Interference plus Noise Ratio) or SNR (Signal to Noise Ratio), etc.

[0371] The sensing results acquired by the second network-side device; for example, if the second network-side device has sensing capabilities, then it can generate sensing results. Or, for example, if the second network-side device is an IMS (In-Service Management System), then it can acquire sensing results from the core network sensing function. The core network sensing function obtains sensing results based on the sensing measurements taken by the base station. The base station can perform sensing through self-transmitted and self-received sensing signals, or by receiving sensing signals sent by other base stations or terminals. Sensing results include whether there is a Line of Sight (LOS) path between the terminal and the serving cell, etc.

[0372] The target cell load information corresponding to the QoE measurement, such as uplink physical resource block (PRB) utilization, downlink PRB utilization, number of active users, uplink throughput, or downlink throughput. This information may be serving cell load information and / or neighboring cell load information;

[0373] Terminal-level performance information, such as average uplink RLC (Radio Link Control) throughput, average downlink RLC throughput, average packet delay (uplink, downlink, or round trip), and average packet loss rate (uplink / downlink average packet loss rate).

[0374] The QoE measurement includes at least one of the following:

[0380] AI model inference accuracy, AI model inference latency, AI model training latency, AI model training accuracy, AI service computing speed, and AI service computing intensity;

[0381] Calculate latency, calculation speed, calculation intensity, and calculation failure rate (or calculation success rate); for example, the calculation failure rate is calculated as the number of failed requests per unit time (e.g., per second, per 5 minutes, per day, etc.) divided by the total number of valid requests per unit time; as another example, the calculation success rate is calculated as the number of successful requests per unit time (e.g., per second, per 5 minutes, per day, etc.) divided by the total number of valid requests per unit time.

[0382] Optionally, the terminal can determine whether to perform cell handover based on the QoE prediction of neighboring cells.

[0383] In some embodiments, if the second network-side device accepts a QoE measurement request and the transmission type is "no report," then the terminal receives a configuration message sent by the second network-side device. The second network-side device (or the second network-side device interacting with other network functions) discovers or analyzes the terminal's quality of experience (QoS) issues and sends a configuration message to the terminal to optimize the QoS. The configuration message may include switching configuration information, uplink resource configuration, downlink resource configuration, and QoS parameter configuration. For example, for terminals in a subway scenario, the ultimate goal is to enable terminals inside the carriage to access cells covering the track area, and terminals on the platform to access cells covering the platform area.

[0384] In summary, in the QoE measurement method provided in this application embodiment, the terminal requests a second network-side device to measure its QoE via an auxiliary measurement request. This allows the second network-side device to measure the terminal's QoE based on the auxiliary measurement request and obtain a QoE report. This facilitates QoE monitoring and optimization for the terminal by the second network-side device and saves on QoE report transmission overhead. It is understood that this application embodiment also supports the terminal requesting the network to collect its QoE. This allows the terminal to obtain QoE information from the application server side, and the network can also perform network configuration based on the terminal's QoE collection to achieve a rapid QoE optimization loop, saving QoE report transmission resources.

[0385] like Figure 5As shown in the embodiments of this application, a QoE measurement method is also provided, the method comprising:

[0386] Step 501: The terminal sends an auxiliary measurement request to the second network-side device, the auxiliary measurement request being used to request the second network-side device to measure the QoE of the terminal;

[0387] Step 502: The terminal receives an auxiliary measurement response sent by the second network-side device, the auxiliary measurement response being used to indicate whether to accept or reject the auxiliary measurement request.

[0388] In some embodiments, the second network-side device receives a network-assisted QoE measurement request sent by the terminal. The second network-side device (or interacting with other network functions) determines whether to accept the network-assisted QoE measurement request. The second network-side device sends a network-assisted QoE measurement response to the terminal. The network-assisted QoE measurement response includes at least an acceptance or rejection option to indicate whether the QoE measurement request is accepted or rejected. Optionally, if the QoE request is rejected, the QoE measurement response may further include a rejection reason, such as insufficient resources.

[0389] In this embodiment, the second network-side device can be a wireless access network node (such as a base station), a core network function node (such as an AMF), or a new service function node, without specific limitations. Among these, the new service function node may potentially be a data plane function (DPF), a sensing function (SF), an artificial intelligence function (AIF), a computing function (CF), an AI control function (AICF), a computing control function (CCF), an external service AI function (NET for AIF), an internal service AI function (such as a network data analytics function (NWDAF)), an external service computing function (NET for Computing function (NETforCF), an internal service computing function (Computing for NET function (CforNETF), an internal service sensing function (Sensing for NET function), or an external service sensing function (NET for Sensing function), etc.

[0390] This application embodiment assumes that the network can obtain the terminal's QoE, and the terminal requests the network to assist in QoE measurement and collection. As mentioned above, terminal QoE measurement and reporting typically requires the collaboration of the terminal's modem, operating system, and application functions. For services provided by operators, such as the aforementioned multimedia telephony service of the Internet Protocol Multimedia Subsystem, operator-provided sensing services, AI services, or computing services, the network can obtain the terminal's QoE. Simultaneously, some OTT application servers also cooperate with operators, so the network may also obtain the QoE of terminals providing these cooperative services. Furthermore, network-assisted terminal QoE measurement and collection helps the network monitor and optimize the user experience for that terminal, and can save on QoE report transmission overhead.
