Description

[0001] [Cross-reference to related applications]

[0002] This application claims priority to U.S. Provisional Application No. 63 / 229,514, filed August 5, 2021. The entire contents of the aforementioned patent application are incorporated herein by reference and constitute a part of this specification. Technical Field

[0003] This disclosure generally relates to the field of communication technology, and more specifically to a user equipment and a method related to report management. Background Technology

[0004] In new radio (NR) quality of experience (QoE), open-layer measurement collection is supported. This feature enables the collection of open-layer measurements from user equipment (UE). Open-layer measurement configurations can be received from operation, administration, and maintenance (OAM) entities or core network (CN) entities, and QoE measurements of the UE's open layer will be performed based on these configurations.

[0005] It should be noted that the radio access network (RAN) may experience overload. RAN overload can last for several hours (e.g., half a day). In the event of RAN overload, the RAN can stop new QoE measurement configurations, release existing QoE measurement configurations, and suspend QoE measurement reporting. However, the suspension operation may affect all QoE measurement configurations, and some high-priority QoE reports will also be suspended. High-priority QoE reports can specify particular performance characteristics. Without receiving high-priority QoE reports from the UE, network deployment or optimization may fail or produce adverse results. Summary of the Invention

[0006] Therefore, this disclosure relates to user equipment (UE) and methods related to report management.

[0007] In one of the exemplary embodiments, a method related to report management and applicable to a UE includes, but is not limited to, the following steps: receiving event triggering information for Quality of Experience (QoE) measurement configuration; receiving a pause indication; determining, based on the event triggering information, to send or pause one or more QoE reports. The QoE reports are associated with the QoE measurement configuration.

[0008] In one exemplary embodiment, a UE includes, but is not limited to, a transceiver and a processor. The processor is coupled to the transceiver. The processor is configured to perform the following steps: receiving event triggering information for QoE measurement configuration; receiving a pause indication; and determining, based on the event triggering information, to send or pause one or more QoE reports. The QoE reports are associated with the QoE measurement configuration.

[0009] However, it should be understood that the content of this invention may not include all aspects and embodiments disclosed herein, and is not intended to limit or constrain in any way, and those skilled in the art will understand and will appreciate that the invention disclosed herein encompasses obvious improvements and modifications to the invention.

[0050] Alternatively, a 5G system or 5G network may also be referred to as a New Radio (NR) system or NR network.

[0051] Figure 1A network device 120 and a UE 130 are shown. Optionally, the communication system 100 may include multiple network devices 120, and the coverage area of ​​each network device 120 may include an additional number of UEs 130, which is not limited in this embodiment.

[0052] Optionally, the communication system 100 may also include other network entities, such as network controllers, mobility management entities, etc., which are not limited in the embodiments of this disclosure.

[0053] It should be understood that, in embodiments of this disclosure, a device with communication capabilities in a network / system may be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include network equipment 120 and UE 130 with communication functions, and network equipment 120 and UE 130 may be the specific equipment mentioned above, which will not be described in detail here; the communication equipment may also include other equipment in the communication system 100, such as mobility management entity (MME), serving gateway (S-GW), public data network (PDN) gateway (P-GW), OAM entity, measurement collection entity, etc., which are not limited in the embodiments of this disclosure.

[0054] Before introducing the embodiments of this disclosure, some related technologies will be introduced first.

[0055] 1. QoE service types:

[0056] NR QoE supports application layer measurement collection. This feature enables the collection of application layer measurements from the UE. Supported service types include streaming service, multimedia telephony service for IP multimedia subsystem (MTSI) service, virtual reality (VR), multimedia broadcast / multicast service (MBMS), and extended reality (XR). However, additional service types are not excluded.

[0057] 2. QoE Measurement Process:

[0058] Figure 2 This is a signaling flowchart of a Quality of Experience (QoE) process according to an exemplary embodiment of this disclosure. (Refer to...) Figure 2The process is used to activate QoE measurements configured by OAM 111. OAM 111 sends the QoE measurement configuration to network device 120 (step S210). Network device 120 finds multiple qualified UEs 130 or a single specific UE 130 that meet the criteria (e.g., area range, application layer capabilities, service type, etc.). Network device 120 sends the QoE measurement configuration carried by an RRC message to the radio resource control (RRC) layer 131 of the specific UE 130 or each qualified UE 130 (step S220). The UE RRC layer 131 forwards the QoE measurement configuration to the UE application (APP) layer 133. When the session begins, the UE APP layer 133 checks the criteria of the QoE measurement configuration (e.g., cell list, service type, etc.), and if the criteria are met, QoE measurement and reporting begin.

[0059] UE APP layer 133 forwards the QoE report to UE RRC layer 131 (step S240). UE RRC layer 131 sends the QoE report to network device 120 in the NR via a separate signaling radio bearer (SRB) (separate from the current SRB) (step S250), because this report has lower priority than other SRB transmissions. Network device 120 then transmits the QoE report to the configured final destination (e.g., measurement collection entity (MCE) 113 or trace-collection entity (TCE)) (step S260).

[0060] 3. RAN overload:

[0061] In cases of RAN overload in standalone connectivity, the RAN can stop new QoE measurement configurations, release existing QoE measurement configurations, and suspend QoE measurement reporting. Network device 120 uses RRC signaling to instruct UE 130 to suspend or resume QoE reporting. Potential solutions for the suspension / resumption mechanism require detailed process specifications (e.g., suspension / resumption of all QoE reports or suspension / resumption of each QoE configuration), the time the UE can store reports, and limitations on the size of stored reports, etc.

[0062] 4. RAN-visible QoE information reported by the UE:

[0063] Because legacy QoE metrics are assembled by OAM, transmitted within a container, and intended to be processed by measurement collection entities within the network, the RAN (e.g., network device 120) may not understand or use legacy QoE metrics. If the RAN needs to use the QoE concept, it may require that QoE information be visible to the RAN. RAN-visible QoE information is simplified QoE information extracted by the UE from the QoE metrics, which the RAN can use for various types of optimization.

[0064] The NG-RAN node assembles the RAN-visible QoE configuration and sends it to the UE. The QoE configuration can be sent directly or via the CN along with a QoE measurement configuration container transmitted from the OAM.

[0065] The UE receives and applies the RAN-visible QoE configuration and / or QoE measurement configuration container. The RAN-visible QoE configuration allows the reported corresponding RAN-visible QoE information to be a unique value or a combination of values ​​reflecting QoE metrics useful to the RAN (e.g., buffer level). The RAN-visible report is provided from the UE's application layer to the UE's RRC layer via AT commands. The UE's RRC layer then includes the RAN-visible report along with the QoE report container (but as a separate IE) in a MeasReportAppLayer IE and sends it to the RAN.

[0066] One or more embodiments of this disclosure provide a method related to report management that selectively provides partial reports based on QoE measurement configuration and / or selectively based on RAN-visible QoE configuration during a pause in QoE reporting.

[0067] Figure 3 This is a flowchart of a method applicable to a user equipment (UE) 130 according to an exemplary embodiment of this disclosure. (Refer to...) Figure 3 UE 130 receives a pause instruction with report selection information (step S310). UE 130 sends one or more QoE reports based on the report selection information (step S330).

[0068] Specifically, a pause instruction is sent from network device 120. The pause instruction is an indication of an action that temporarily halts QoE measurement reporting. The pause instruction is a unicast or broadcast from network device 120. Optionally, the QoE measurement can be an application-layer measurement configured by OAM. Alternatively, the QoE measurement can be a radio-layer measurement. Alternatively, the QoE measurement can be related to RAN-visible QoE, which includes RAN-visible QoE metrics (e.g., downtime, round-trip time, or jitter duration) and RAN-visible QoE values.

[0069] In one embodiment, the pause indication is related to RAN overload. For example, network device 120 detects RAN overload, and UE 130 receives a pause indication from network device 120 in response to the RAN overload. In other embodiments, the pause indication may be triggered by other events, such as a fault or power problem.

[0070] On the other hand, recovery is the action of resuming previously suspended QoE measurement reports. In one embodiment, UE130 may receive a recovery instruction from network device 120. The recovery instruction is an indication of the recovery action.

[0071] For example, Figure 4 This is a signaling flowchart of a QoE process with a pause and resume mechanism according to an exemplary embodiment of this disclosure. (Refer to...) Figure 4 The network device 120 detects RAN overload (step S420). The network device 120 sends a pause instruction to the UE 130 (step S430). When the UE 130 receives the pause instruction, the state of the QoE measurement report changes from the normal state NS to the paused state PS of the QoE report. Furthermore, the RAN overload is released later (step S450). The network device 120 sends a recovery instruction to the UE 130 (step S460). When the UE 130 receives the recovery instruction, the state of the QoE measurement report changes from the paused state PS to the normal state NS of the QoE report.

[0072] It should be noted that the pause / resume mechanism can be applied to all QoE reports (e.g., RAN-visible reports or normal QoE reports), per QoE measurement configuration, or per RAN-visible QoE configuration.

[0073] In one embodiment, the report selection information is associated with avoiding report pauses for one or more QoE measurement configurations. One or more QoE reports (hereinafter referred to as first QoE reports) may be associated with a QoE measurement configuration that is related to a report pause indicated in the report selection information. During a pause state PS, the one or more first QoE reports associated with the QoE measurement configuration related to avoiding report pauses are sent.

[0074] In one embodiment, one or more second QoE reports, in addition to the one or more first QoE reports, are paused based on report selection information. The second QoE reports are not associated with QoE measurement configurations related to avoiding report pauses indicated in the report selection information. This means that the transmission of first QoE reports will not be paused during the paused state PS of QoE reports (e.g., ...). Figure 4(See step S440). However, the transmission of a second QoE report not associated with the QoE measurement configuration indicated by the report selection information will be paused during the QoE report pause state PS.

[0075] In one embodiment, UE 130 receives a group identifier (such as QoE measurement configuration) from network device 120. Figure 4 (See step S410). A group identifier (or category, attribute, or tag) represents a group that either does not include a QoE measurement configuration or includes at least one QoE measurement configuration. Alternatively, the group identifier represents either a QoE measurement configuration or a RAN-visible configuration. In one embodiment, the group identifier is an identifier of a QoE measurement configuration. In another embodiment, the group identifier is an identifier of a RAN-visible QoE configuration. In one embodiment, the group identifier is a service type and / or Radio Resource Control (RRC) level identification (ID) (e.g., a reference ID or simply ID). Service types may be, for example, MTSI, VR, MBMS, XR services, etc. Group identifiers may be numbers, symbols, letters, or text, and embodiments are not limited thereto.

[0076] In one embodiment, the group identifier of the QoE measurement configuration is associated with QoE priority. For example, the QoE priority of the QoE measurement configuration is lower than the QoE priority of the RAN-visible QoE configuration. Furthermore, the reported selection information is a priority threshold. Figure 4 In one embodiment of step S440, UE130 may further compare the QoE priority of the QoE measurement configuration with a priority threshold, and send the QoE measurement configuration based on the comparison result of the priority threshold. In other words, the first QoE report is selected based on the comparison result between the QoE priority and the priority threshold.

[0077] For example, Figure 5A This is a schematic diagram illustrating a portion of a report according to an exemplary embodiment of this disclosure. (Refer to...) Figure 5AThe report selects a priority threshold, which is set to 1. QoE measurement configuration QoE 1 has a QoE priority of 1, QoE measurement configuration QoE 2 has a QoE priority of 2, and QoE measurement configuration QoE 3 has a QoE priority of 3. It is assumed that a smaller QoE priority value indicates higher priority, and a larger QoE priority value indicates lower priority. The QoE priority values ​​of QoE measurement configurations QoE 2 and QoE 3 are greater than the priority threshold (i.e., in the comparison results), meaning that QoE measurement configurations QoE 2 and QoE 3 have lower QoE priorities. The QoE priority value of QoE measurement configuration QoE 1 is less than the priority threshold (i.e., in the comparison results), meaning that QoE measurement configuration QoE 1 has higher QoE priority. Therefore, in response to receiving the pause instruction, the reporting of QoE measurement configurations QoE 2 and QoE 3 is paused (i.e., the reporting of QoE measurement configurations QoE 2 and QoE 3 is the second QoE report), while the reporting of QoE measurement configuration QoE 1 remains unchanged (i.e., the reporting of QoE measurement configuration QoE 1 is the first QoE report and will be sent by UE RRC layer 131).

[0078] In one embodiment, the group identifier configured for QoE measurement is related to the reporting volume. A higher reporting volume and more QoE may increase the probability of RAN overload. Furthermore, the reporting selection information is a volume threshold. Figure 4 In one embodiment of step S440, the UE 130 may further compare the number of QoE reports with a quantity threshold, and send a QoE report based on the comparison result of the quantity threshold. In other words, a first QoE report is selected based on the comparison result between the number of reports and the quantity threshold. In some embodiments, the number of reports is related to the time during which the UE 130 can store QoE reports.

[0079] For example, Figure 5B This is a schematic diagram illustrating a portion of a report according to an exemplary embodiment of this disclosure. (Refer to...) Figure 5BThe report selection information is the quantity threshold, which is set to 0.7. The overload factor is related to the reporting quantity. It is assumed that the smaller the value, the higher the overload factor for the reporting quantity, and vice versa. The overload factor for QoE measurement configuration QoE 1 is 0.8, for QoE measurement configuration QoE 2 it is 0.5, and for QoE measurement configuration QoE 3 it is 0.2. The overload factor values ​​for QoE measurement configurations QoE 2 and QoE 3 are less than the quantity threshold (i.e., the comparison result), indicating that the reporting quantity for QoE measurement configurations QoE 2 and QoE 3 is larger. The overload factor value for QoE measurement configuration QoE 1 is greater than the quantity threshold (i.e., the comparison result), indicating that the reporting quantity for QoE measurement configuration QoE 1 is smaller. Therefore, in response to receiving the pause instruction, the reporting of QoE measurement configurations QoE 2 and QoE 3 is paused (i.e., the reporting of QoE measurement configurations QoE 2 and QoE 3 is the second QoE report), while the reporting of QoE measurement configuration QoE 1 remains unchanged (i.e., the reporting of QoE measurement configuration QoE 1 is the first QoE report and will be sent by UE RRC layer 131).

[0080] In one embodiment, the reporting selection information is a bitmap configuration. Each bit of the bitmap configuration corresponds to a group identifier for a QoE measurement configuration (i.e., one bit for each QoE measurement configuration). Optionally, the relationship between the bitmap configuration and the QoE measurement configuration can be ordered. Alternatively, the relationship between the bitmap configuration and the QoE measurement configuration can be a flexible one-to-many mapping. Figure 4 In one embodiment of step S440 shown, UE 130 may further compare the group identifier of the QoE measurement configuration with the bitmap configuration, and send a QoE report based on the comparison result of the bitmap configuration. In other words, a first QoE report is selected based on the comparison result of the group identifier and the bitmap configuration.

[0081] For example, Figure 6 This is a schematic diagram illustrating a portion of a report according to an exemplary embodiment of this disclosure. (Refer to...) Figure 6The relationship between the bitmap configuration and the QoE measurement configuration is ordered. The first bit represents QoE measurement configuration QoE 1, the second bit represents QoE measurement configuration QoE 2, and the third bit represents QoE measurement configuration QoE 3. If the bitmap configuration is "101", since the second bit of the bitmap configuration is "0", only the reporting of QoE measurement configuration QoE 2 is paused (i.e., the reporting of QoE measurement configuration QoE 2 is the second QoE report), and since the first and third bits of the bitmap configuration are "1", the reporting of QoE measurement configurations QoE 1 and QoE 3 remains unchanged (i.e., the reporting of QoE measurement configurations QoE 1 and QoE 3 is the first QoE report and will be sent by UE RRC layer 131).

[0082] In one embodiment, the group identifier is associated with a unique identifier in the QoE measurement configuration. Report selection information may include a list of unique identifiers. This means that one or more unique identifiers will be selected. Figure 4 In step S440, UE130 may further compare the group identifier configured for QoE measurement with the unique identifier in the list, and send a QoE report based on the comparison result of the unique identifier in the list. In other words, the first QoE report is selected based on the comparison result of the group identifier and the unique identifier in the list. The comparison result will be either the unique identifier being the same as or different from the group identifier configured for QoE measurement.

[0083] For example, Figure 7 This is a schematic diagram illustrating a portion of a report according to an exemplary embodiment of this disclosure. (Refer to...) Figure 7 The report selection information includes the RRC level ID of QoE measurement configuration QoE 2. Therefore, in response to receiving the pause instruction, the reporting of QoE measurement configurations QoE 1 and QoE 3 is paused (i.e., the reporting of QoE measurement configurations QoE 1 and QoE 3 is the second QoE report), while the reporting of QoE measurement configuration QoE 2 remains unchanged (i.e., the reporting of QoE measurement configuration QoE 2 is the first QoE report and will be sent by UE RRC layer 131).

[0084] In one embodiment, UE 130 receives a recovery indication and, in response to receiving the recovery indication, sends one or more second QoE reports based on the recovery indication. This recovers the second QoE reports that were suspended during the paused state PS. Figure 7 For example, in response to receiving a recovery instruction, the report will restore the QoE measurement configurations QoE 1 and QoE 3.

[0085] Figure 8 This is a flowchart of a method applicable to network device 120 according to an exemplary embodiment of this disclosure. (Refer to...) Figure 8Network device 120 sends a pause instruction with report selection information (step S810). Network device 120 receives one or more QoE reports based on the report selection information (step S830).

[0086] For detailed explanations of steps S810 to S830, please refer to [link / reference]. Figures 3 to 7 And it will be omitted.

[0087] In one embodiment, network device 120 sends a group identifier (e.g., QoE measurement configuration) to UE 130. Figure 4 (See step S410). A group identifier (or category, attribute, or label) represents one of the QoE measurement configurations. In one embodiment, the group identifier is an identifier of the QoE measurement configuration. In another embodiment, the group identifier is an identifier of the RAN-visible QoE configuration. In one embodiment, the group identifier is a service type and / or radio resource control (RRC) level identifier (ID) (e.g., a reference ID or simply ID).

[0088] In one embodiment, the group identifier of the QoE measurement configuration is associated with QoE priority. Report selection information is a priority threshold, and the first QoE report is selected based on a comparison between the QoE priority and the priority threshold.

[0089] In one embodiment, the group identifier is associated with the reporting volume. The report selection information is a volume threshold, and the first QoE report is selected based on a comparison between the reporting volume and the volume threshold.

[0090] In one embodiment, the report selection information is a bitmap configuration. One bit of the bitmap configuration corresponds to a group identifier, and the first QoE report is selected based on a comparison between the group identifier and the bitmap configuration.

[0091] In one embodiment, the group identifier is associated with a unique identifier in the QoE measurement configuration, and the report selection information may include a list of multiple unique identifiers and select a first QoE report based on the list of unique identifiers.

[0092] In one embodiment, network device 120 may receive one or more second QoE reports without being based on reporting selection information. The second QoE reports are not associated with QoE measurement configurations related to avoiding reporting suspension indicated in the reporting selection information.

[0093] In one embodiment, network device 120 sends a recovery instruction (such as...). Figure 4 As shown in step S460), and in response to sending a recovery indication, receiving one or more second QoE reports based on the recovery indication (such as...). Figures 5A to 7 (As shown). A second QoE report will be received after the recovery instruction is sent.

[0094] However, the first QoE report can be selected based on the triggering event rather than the report selection information.

[0095] Figure 9 This is a flowchart of a method applicable to UE 130 according to one of the exemplary embodiments of this disclosure. (Refer to...) Figure 9 UE 130 receives event triggering information for QoE measurement configuration (step S910). UE 130 receives a pause indication (step S930). UE 130 decides to send or pause one or more QoE reports based on the event triggering information (step S950).

[0096] Specifically, QoE reports are associated with QoE measurement configurations. In one embodiment, event triggering information is associated with an event that the measurement result corresponding to the QoE measurement configuration meets the criteria, and the UE decides to send or suspend the one or more QoE reports based on the event triggering information.

[0097] In one embodiment, the standard is associated with the measurement results corresponding to the QoE measurement configuration. In one embodiment, the measurement results corresponding to the QoE measurement configuration are included in the Radio Access Network (RAN) visible QoE information. For example, the measurement results are RAN visible QoE information (or RAN visible QoE values) reported by UE 130.

[0098] In one embodiment, the RAN-visible QoE information metric can be the corruption duration of the streaming service. If network device 120 is aware of the result of this metric, network device 120 can adjust the resource allocation of UE 130 to meet user experience requirements.

[0099] In another embodiment, the RAN-visible QoE information metric can be the buffer level of the flow service. If network device 120 is aware of the buffer level, it can adjust the resource allocation of UE 130 to ensure sufficient buffering for the flow, thereby improving scheduling efficiency.

[0100] In other embodiments, the RAN-visible QoE information metric may be the third-generation partner program (3GPP). rd Other metrics defined in Generation Partnership Project (3GPP) TR 38.890, etc. In yet another embodiment, measurement results can be derived from data of other QoE metrics via a model / function.

[0101] The pause instruction in this embodiment is different from the above embodiment (e.g.) Figures 3 to 8The difference between the pause instructions in the illustrated embodiment is that the pause instruction in this embodiment is received without the report selection information mentioned in the previous embodiments. However, one or more first QoE reports with measurement results corresponding to a QoE measurement configuration that meets the criteria are sent, and one or more second QoE reports with measurement results corresponding to a QoE measurement configuration that does not meet the criteria are paused. In other words, the first QoE report is selected based on a trigger event.

[0102] Figure 10 This is a signaling flowchart of a QoE process with a pause and resume mechanism according to an exemplary embodiment of this disclosure. (Refer to...) Figure 10 Network device 120 sends event triggering information for QoE measurement configuration to UE 130 (step S1010). RAN overload is detected by network device 120 (step S1020). Network device 120 sends a pause indication to UE 130 (step S1030). When UE 130 receives the pause indication, the state of the QoE measurement report changes from the normal state NS to the paused state PS of the QoE report. Furthermore, the RAN overload is released later (step S1050). Network device 120 sends a recovery indication to UE 130 (step S1060). When UE 130 receives the recovery indication, the state of the QoE measurement report changes from the paused state PS to the normal state NS of the QoE report.

[0103] The pause / resume mechanism can be applied to all QoE reports (e.g., RAN-visible reports or normal QoE reports), per QoE measurement configuration, or per RAN-visible QoE configuration.

[0104] exist Figure 9 The steps shown in S950 or Figure 10 In one embodiment of step S1040, the UE 130 compares the measurement result corresponding to the QoE measurement configuration with the measurement threshold, and decides to send or suspend one or more QoE reports based on the comparison result of the measurement threshold.

[0105] Taking the duration of damage as an example, UE 130 compares the value or measurement result corresponding to the duration of damage with a duration threshold (i.e., a measurement threshold). UE 130 may consider an entry condition in response to a first condition-met event and a departure condition in response to a second condition-met event.

[0106] For example, the first condition is:

[0107] Ms–Hys>Thresh…(1).

[0108] The second condition is:

[0109] Ms+Hys <Thresh…(2)

[0110] Ms is the measurement corresponding to the duration of damage as measured by the RAN visible QoE, without considering any bias. Hys is the hysteresis parameter for this event (i.e., the hysteresis defined within the reportConfigNR-QoE for this event), however, the hysteresis parameter can be omitted based on practical requirements. Thresh is the measurement threshold for this event (i.e., q1-Threshold defined within the reportConfigNR-QoE for this event). Ms is expressed in microseconds (ms). Hys is expressed in the same units as Ms. Thresh is expressed in the same units as Ms.

[0111] Figure 11 This is a schematic diagram illustrating a portion of a report according to an exemplary embodiment of this disclosure. (Refer to...) Figure 11 The measurement threshold corresponding to QoE measurement configuration QoE 1 is q1-Threshold-1, the measurement threshold corresponding to QoE measurement configuration QoE 2 is q1-Threshold-2, and the measurement threshold corresponding to QoE measurement configuration QoE 3 is q1-Threshold-3. An asterisk (*) indicates an event that meets its corresponding criterion, such as a measurement result greater than the measurement threshold q1-Threshold-1 corresponding to QoE measurement configuration QoE 1. This can be used in conjunction with the hysteresis parameter as a function (1) as needed. Therefore, the report of QoE measurement configuration QoE 1 will be considered the first QoE report for the event and will be sent. On the other hand, a square (*) indicates an event that does not meet its corresponding criterion, such as a measurement result less than the measurement threshold q1-Threshold-3 corresponding to QoE measurement configuration QoE 3. Therefore, the report of QoE measurement configuration QoE 3 will be considered the second QoE report for the event and will be suspended.

[0112] In one embodiment, the event triggering information is associated with an event that meets a criterion and a randomly selected random value corresponding to the QoE measurement configuration, and the UE decides to send or suspend the at least one QoE report based on the event triggering information. For example, the criterion may be a check factor for a report check. The report check may be randomly selected. Alternatively, the report check may be associated with checks on report volume, priority, importance, user needs, service requirements, etc., and the embodiments are not limited thereto. Optionally, the check factor may be a value or symbol representing the status or measurement result of the report check.

[0113] exist Figure 9 The steps shown in S950 or Figure 10In one embodiment of step S1040, the UE 130 compares a random value corresponding to the QoE measurement configuration with a threshold, and decides to send or suspend one or more QoE reports based on the comparison result of the threshold. In other words, one or more first QoE reports are selected based on the comparison result between the random value of the QoE measurement and the threshold.

[0114] In one embodiment, UE 130 randomly selects a value based on a random distribution to achieve random selection. The random distribution may be, for example, a uniform distribution, a Gaussian distribution, or other distributions.

[0115] For example, network device 120 configures UE 130 such that QoE measurement configuration QoE 1 has a check factor of 0.8, QoE measurement configuration QoE 2 has a check factor of 0.5, and QoE measurement configuration QoE 3 has a check factor of 0.2. The check factor is a threshold. UE 130 can plot a random number “rand” uniformly distributed within the range: 0 ≤ rand < 1. If the random number “rand” is lower than the value indicated by the corresponding check factor (i.e., the event meets the criteria), its QoE report will be considered the first QoE report triggering the event and will be sent to network device 120 during the PS state. On the other hand, if the random number “rand” is not lower than the value indicated by the corresponding check factor (i.e., the event does not meet the criteria), its QoE report will be considered the second QoE report and will be suspended (i.e., not sent).

[0116] In one embodiment, UE 130 may receive a recovery indication from network device 120, and if the one or more QoE reports are suspended, it may send the one or more QoE reports based on the recovery indication in response to receiving the recovery indication. The suspended QoE reports have measurement results corresponding to the QoE measurement configuration or random values ​​that do not meet the criteria.

[0117] Figure 12 This is a flowchart of a method applicable to network device 120 according to an exemplary embodiment of this disclosure. (Refer to...) Figure 12 Network device 120 sends event triggering information for QoE measurement configuration (step S1210). Network device 120 sends a pause indication (step S1230). In response to sending the pause indication, network device 120 receives one or more QoE reports based on the event triggering information (step S1250).

[0118] For detailed explanations of steps S1210 to S1250, please refer to [link / reference]. Figures 9 to 11And this will be omitted. One or more QoE reports are associated with a QoE measurement configuration. In one embodiment, event triggering information is associated with an event that the QoE measurement result corresponding to the QoE measurement configuration meets a criterion. Furthermore, network device 120 receives one or more first QoE reports with an event corresponding to a QoE measurement result that meets a criterion, and network device 120 does not receive one or more second QoE reports with a QoE measurement result corresponding to a QoE measurement configuration that does not meet a criterion.

[0119] In one embodiment, one or more QoE reports are sent or paused based on a comparison between the measurement result corresponding to the QoE measurement configuration and the measurement threshold.

[0120] In another embodiment, the event triggering information is associated with an event in which a randomly selected random value corresponding to the QoE measurement configuration meets a criterion. In one embodiment, sending or pausing one or more QoE reports is determined by the UE 130 based on a comparison between the random value corresponding to the QoE measurement configuration and a threshold.

[0121] In one embodiment, network device 120 sends a recovery instruction (such as...). Figure 10 As shown in step S1060), and if one or more QoE reports are paused, then in response to sending a recovery instruction, the one or more QoE reports are received based on the recovery instruction (e.g., ...). Figure 10 (As shown). A second QoE report will be received after the recovery instruction is sent.

[0122] However, the first QoE report can be sent based on both the report selection information and the triggering event, rather than either the report selection information or the triggering event.

[0123] Figure 13 This is a flowchart of a method applicable to UE 130 according to one of the exemplary embodiments of this disclosure. (Refer to...) Figure 13 UE 130 receives event trigger information (step S1310). UE 130 receives a pause instruction with report selection information (step S1330). Based on both the report selection information and the event trigger information, UE 130 decides to send or pause one or more QoE reports (step S1350).

[0124] For detailed explanations of steps S1310 to S1350, please refer to [link / reference]. Figures 3 to 11 And will be omitted. This embodiment differs from the above embodiments (e.g.) Figures 3 to 11 The difference between the embodiments shown is that, in this embodiment, both report selection information and event triggering information are considered. This means that one or more first QoE reports are indicated by report selection information and have an event (which meets the corresponding criteria).

[0125] Figure 14 This is a signaling flowchart of a QoE process with a pause and resume mechanism according to an exemplary embodiment of this disclosure. (Refer to...) Figure 14 Network device 120 sends event trigger information and the group identifier of QoE measurement configuration to UE 130, either separately or together (step S1410). Network device 120 detects RAN overload (step S1420). Network device 120 sends a pause indication with report selection information to UE 130 (step S1430). When UE 130 receives the pause indication, the state of QoE measurement report changes from normal state NS to paused state PS of QoE report. UE sends QoE report based on both report selection information and event trigger information (step S1440). In addition, RAN overload is released later (step S1450). Network device 120 sends a recovery indication to UE 130 (step S1460). When UE 130 receives the recovery indication, the state of QoE measurement report changes from paused state PS to normal state NS of QoE report.

[0126] The pause / resume mechanism can be applied to all QoE reports (e.g., RAN-visible reports or normal QoE reports), per QoE measurement configuration, or per RAN-visible QoE configuration.

[0127] For example, Figure 15 This is a schematic diagram illustrating a portion of a report according to an exemplary embodiment of this disclosure. (Refer to...) Figure 15Assuming the report selection information is a priority threshold, and the event criteria are related to RAN-visible QoE (e.g., duration of damage), network device 120 configures UE 130 as follows: QoE priority for QoE measurement configuration QoE 1 is 1, QoE priority for QoE measurement configuration QoE 2 is 2, and QoE priority for QoE measurement configuration QoE 3 is 3. Furthermore, network device 120 configures UE 130 as follows: the measurement threshold corresponding to QoE measurement configuration QoE 1 is q1-Threshold-1, the measurement threshold corresponding to QoE measurement configuration QoE 2 is q1-Threshold-2, and the measurement threshold corresponding to QoE measurement configuration QoE 3 is q1-Threshold-3. Network device 120 sends a pause indication with a priority threshold (e.g., 1). When the criteria for an event with a measurement threshold q1-Threshold-1 are met (shown as an asterisk in the diagram), UE 130 will send a QoE report corresponding to QoE measurement configuration QoE1 to network device 120, and suspend all QoE reports corresponding to QoE measurement configurations QoE2 and QoE3 due to their lower QoE priority. However, when the criteria for an event with a measurement threshold q1-Threshold-1 are not met (shown as a square in the diagram), QoE reports corresponding to QoE measurement configuration QoE1 can be suspended.

[0128] Figure 16 This is a flowchart of a method applicable to network device 120 according to an exemplary embodiment of this disclosure. (Refer to...) Figure 16 Network device 120 sends event trigger information (step S1610). Network device 120 sends a pause instruction with report selection information (step S1630). In response to sending the pause instruction, network device 120 receives one or more QoE reports based on both the report selection information and the event trigger information (step S1650).

[0129] For detailed explanations of steps S1610 to S1650, please refer to [link / reference]. Figure 13 Steps S1310 to S1350 shown will be omitted.
