[0040] Figure 1 An example communication network 100 in which embodiments of the present disclosure may be implemented is shown. Figure 1As shown, the communication network 100 may include a terminal device 110 (hereinafter also referred to as UE 110 or first device 110). The communication network 100 may also include a network device 120 (hereinafter also referred to as gNB 120 or second device 120). The network device 120 can manage cell 102. The terminal device 110 and the network device 120 can communicate with each other within the coverage area of ​​cell 102.

[0041] It should be understood that Figure 1 The number of network devices and terminal devices shown is given for illustrative purposes and does not imply any limitation. Communication network 100 may include any suitable number of network devices and terminal devices.

[0042] As mentioned above, the QoE process in NR can refer to both signaling-based and management-based processes.

[0043] During signaling-based processes, the core network (CN) can initiate the activation of QoE measurements configured by the operations and maintenance (OAM) entity and send the QoE measurement configuration to the gNB. The gNB can also forward the QoE measurement configuration to a specific UE via RRC signaling. The UE access layer (AS) should then send the QoE measurement configuration to the UE application layer.

[0044] During the management-based process, the OAM entity can send QoE measurement configurations to the gNB. The gNB can identify multiple qualified UEs or a single specific UE that meet the criteria (e.g., area range, application layer capabilities, service type, etc.). The gNB can also send the QoE measurement configurations to a specific UE or the AS layer of each qualified UE. The UE AS layer should then send the QoE measurement configurations to the UE application layer.

[0045] In NR, it can still be assumed that the QoE measurement configuration is transmitted from the gNB to the UE AS layer within the AS container. This configuration will be passed in the DL RRC message "RRCReconfiguration," where the QoE measurement trigger is included in the AS container, and the QoE measurement trigger is transparent to both the gNB and the UE AS layer. Multiple measurements can be configured for the UE simultaneously.

[0046] In cases of gNB overload, to alleviate overload on the air interface, the gNB can stop new QoE measurement configurations, release existing QoE measurement configurations, and / or temporarily suspend QoE measurement reporting. The applicability of QoE configurations to different RRC states introduces additional complexity when handling unexpected application layer reports to the UE AS layer. In the worst-case scenario, the UE's RRC connection is released, and the UE's application layer can generate a report storm with reporting intervals, unable to transmit reports to the gNB due to the lack of active RRC connections or suspended RRC reports. Currently, neither the UE AS nor the gNB can control incoming unexpected application layer reports.

[0047] Furthermore, it has been agreed that a UE can be configured to perform multiple simultaneous QoE measurements and report the corresponding results, which also means that multiple QoE measurements will be configured within a single cell. However, the gNB may be unsure how to abort / resume QoE measurement reporting in the context of multiple simultaneous configurations. RRC or SRB4 versions can represent a hard stop for any QoE measurement reporting, although the concept of temporary abort has not yet been defined.

[0048] Therefore, it is expected that some configured QoE measurement reports can be maintained under conditions such as moderate overload, since these QoE measurements are more important than others. It is also expected that the gNB has the ability to control configured QoE measurement reports one by one within a cell. For example, an RRC connection with a low-priority QoE measurement can be released first. When the gNB recovers from the overload condition, it can resume the QoE measurement report with the high-priority configuration first.

[0049] This disclosure provides a solution for prioritizing QoE measurements. In this solution, the UE can receive from the gNB an indication associated with reporting at least one QoE measurement to be performed at a first device, the indication being generated by the gNB based on the corresponding priority of the at least one QoE measurement. Based on this indication, the UE can determine the reporting of the at least one QoE measurement. In this way, the gNB has the ability to control the configuration of QoE measurement reporting by the UE under overload conditions, and under low and medium overload conditions, the QoE reporting of the UE with high priority can be maintained without interruption.

[0050] The following is combined Figures 2-4 The principles and implementation of this disclosure will be explained in detail. Figures 2-4 A schematic procedure for setting priorities for QoE is shown. For discussion purposes, references will be made to... Figure 1 Describe process 200-400. Process 200-400 may involve, for example: Figure 1 The UE 110 and gNB 120 are shown.

[0051] The gNB 120 can obtain information about the corresponding priorities of at least one QoE measurement to be performed by the UE 110 from the CN node or OAM entity. Optionally, the gNB 120 can obtain information about the corresponding priorities of at least one QoE measurement, as well as configuration parameters configured for the at least one QoE measurement, from the CN node or OAM entity. It should be understood that information about the corresponding priorities of at least one QoE measurement can be transmitted to the gNB 120 from the CN node or OAM entity via a separate message. Alternatively, the gNB 120 can also request information about the corresponding priorities of at least one QoE measurement from the CN node or OAM entity. For example, the gNB 120 can send a request for the corresponding priorities of at least one QoE measurement to the CN node or OAM entity.

[0052] like Figure 2 As shown, gNB 120 can generate 202 an indication for UE 110 to report at least one QoE measurement based on obtained information regarding the corresponding priorities of at least one QoE measurement. gNB 120 can then transmit 204 this indication to UE 110. This indication can be transmitted to UE 110 when gNB 120 forwards configuration parameters configured for the at least one QoE measurement to UE 110. Alternatively, gNB 120 can also transmit this indication independently.

[0053] Based on this instruction, UE 110 can obtain information about the corresponding priority of at least one QoE measurement. UE 110 can store the corresponding priority of at least one QoE measurement.

[0054] Under normal circumstances, UE 110 can perform at least one QoE measurement based on the configured measurement parameters and report at least one QoE measurement to gNB 120.

[0055] When gNB 120 determines that the air interface between gNB 120 and UE 110 is overloaded, gNB 120 can determine a first overload level and transmit an indication of the first overload level to UE 110.

[0056] Based on the overload level, UE 110 can determine a first threshold priority for the first overload level. The association between the overload level and multiple threshold priorities can be pre-configured for UE 110. Alternatively, this association can also be transmitted to UE 110 from gNB 120 along with priority information for at least one QoE measurement. It should be understood that this association can be transmitted to UE 110 from gNB 120 via a separate message. For example, this message could be a SIB or RRC-specific message.

[0057] If UE 110 determines that the priority of the first group of QoE measurements in at least one QoE measurement is lower than the determined first threshold priority, UE 110 may stop, suspend, or pause reporting the first group of QoE measurements. In the following text, "suspend QoE measurement reporting" can be understood as the ability to temporarily stop or suspend reporting QoE measurements. UE 110 may report 210 other QoE measurements in at least one QoE measurement besides the first group of QoE measurements.

[0058] If gNB 120 determines that the overload situation has not recovered, gNB 120 may transmit an indication of a second overload level to UE 110. UE 110 may determine a second threshold priority for the second overload level, which may be higher than the first threshold priority.

[0059] Then, UE 110 can stop, abort, or suspend 214 reporting of a second group of QoE measurements out of at least one QoE measurement. The corresponding priority of the second group of QoE measurements can be higher than the first threshold priority and lower than the second threshold priority.

[0060] If gNB 120 determines that the overload situation has recovered, gNB 120 can update the overload level. For example, gNB 120 can transmit an indication of the first overload level to UE 110. Then, UE 110 can resume reporting QoE measurements with a priority higher than the first threshold priority. For example, UE 110 can resume a second set of QoE measurements.

[0061] In some example implementations, for QoE measurements that have been stopped or suspended from reporting, UE 110 may determine whether the results of these QoE measurements should be recorded or discarded based on the corresponding priority of the stopped or suspended QoE measurements.

[0062] For example, as described above, the first group of QoE measurements and the second group of QoE measurements have stopped, aborted, or suspended reporting. UE110 can record the results of the second group of QoE measurements and discard the results of the first group of QoE measurements because the corresponding priority of the second group of QoE measurements is higher than that of the first group of QoE measurements.

[0063] In some example embodiments, if UE 110 determines that the overload condition of gNB 120 has changed, for example, if UE 110 determines that the reporting of the second set of QoE measurements can be resumed, then UE 110 can determine whether the historical results of the second set of QoE measurements have been recorded at UE 110. If UE 110 determines that there are recorded historical results of the second set of QoE measurements, then UE 110 can report the recorded historical results to gNB 120.

[0064] It should be understood that if the corresponding historical results of more than one QoE measurement have been recorded, the UE 110 can report them one after another in priority order of the corresponding priority of the more than one QoE measurement.

[0065] In some example embodiments, indications of multiple overload levels may be transmitted from gNB 120 to UE 110 via RRC signaling. Alternatively, the indication may also be transmitted from gNB 120 to UE 110 via System Information Block (SIB) broadcast. It should be understood that any other suitable signaling may also carry the transmission of this indication.

[0066] Figure 3 Another illustrative procedure for prioritizing QoE is shown. (Compared to...) Figure 2 Similar to the process shown, gNB 120 can generate 302 an indication for UE 110 to report at least one QoE measurement based on the obtained information about the corresponding priority of at least one QoE measurement, and transmit 304 the indication to UE 110.

[0067] In this scenario, gNB 120 can transmit an indication of timer 306, which is used by the UE to detect the overload state of gNB 120. The timer can indicate a time interval within which the UE 110 can determine whether it has received an indication of the overload state of gNB 120 from gNB 120.

[0068] In some example embodiments, the timer indication may be transmitted from gNB 120 to UE 110 via RRC signaling. Alternatively, the indication may also be transmitted from gNB 120 to UE 110 via SIB broadcast. It should be understood that any other suitable signaling may also carry the transmission of this indication.

[0069] UE 110 can detect whether it receives an indication of an overload state from gNB 120 by starting a timer. If UE 110 determines that an overload state is detected before the timer expires, UE 110 can stop or suspend reporting at least one set of QoE measurements in 308. The corresponding priority of the first set of QoE measurements can be lower than the first threshold priority corresponding to the overload state.

[0070] The detection of the overload state of gNB 120 can be performed periodically based on a timer. In some example embodiments, UE 110 can also detect whether it has received an indication of the overload state of gNB 120 from gNB 120 by restarting the timer. If UE 110 fails to detect the overload state before the timer expires, UE 110 can resume the first set of QoE measurements that 310 has stopped or suspended reporting.

[0071] Alternatively, if UE 110 continues to receive indication of an overload state from gNB 120 312 before the timer expires, indicating that the overload state of gNB 120 has not improved after stopping or pausing the reporting of the first group of QoE measurements, then UE 110 may stop or pause the reporting of a second group of QoE measurements in at least one QoE measurement 314. The corresponding priority of the second group of QoE measurements may be higher than the first threshold priority and lower than the second threshold priority.

[0072] Similarly, for QoE measurements that have been stopped or suspended from reporting, UE 110 can determine whether the results of these QoE measurements should be recorded or discarded based on the corresponding priority of the stopped or suspended QoE measurements.

[0073] For example, as described above, the reporting of the first group of QoE measurements and the second group of QoE measurements has stopped or been suspended. UE 110 can record the results of the second group of QoE measurements and discard the results of the first group of QoE measurements because the corresponding priority of the second group of QoE measurements is higher than that of the first group of QoE measurements.

[0074] In some example embodiments, if UE 110 determines that the overload state of gNB 120 has been removed, for example, if UE 110 determines that reporting of the second set of QoE measurements can be resumed, then UE 110 can determine whether the historical results of the second set of QoE measurements have been recorded at UE 110. If UE 110 determines that there are recorded historical results of the second set of QoE measurements, then UE 110 can report the recorded historical results to gNB 120.

[0075] It should be understood that if the corresponding historical results of more than one QoE measurement have been recorded, the UE 110 can report them one after another in priority order of the corresponding priority of the more than one QoE measurement.

[0076] In some example embodiments, an overload status indication may be transmitted from gNB 120 to UE 110 via RRC signaling. Alternatively, the indication may also be transmitted from gNB 120 to UE 110 via System Information Block (SIB) broadcast. It should be understood that any other suitable signaling may also carry the transmission of this indication.

[0077] Now for reference Figure 4 , Figure 4 This illustrates another illustrative process for setting priority for QoE.

[0078] In this case, gNB 120 can be configured with the appropriate priority for at least one QoE measurement to be performed by UE 110.

[0079] When gNB 120 determines that the air interface between gNB 120 and UE 110 is overloaded, gNB 120 can determine the configuration for UE 110 to report at least one QoE measurement based on the corresponding configured priority.

[0080] For example, gNB 120 can determine a first group of QoE measurements that do not need to be reported and / or a second group of QoE measurements that are allowed to be reported, based on the corresponding priority of at least one QoE measurement.

[0081] In some example embodiments, gNB 120 can determine the identifiers of the first set of QoE measurements and the second set of QoE measurements, and generate a configuration based on the identifiers.

[0082] Alternatively, the gNB 120 can also determine the service type of the first set of QoE measurements and the second set of QoE measurements, and generate a configuration based on the service type.

[0083] gNB 120 can transmit configuration 404 to UE 110. After receiving the configuration, UE 110 can stop or pause reporting the first set of QoE measurements 406 and continue reporting the second set of QoE measurements 408.

[0084] When gNB 120 determines that the overload situation has been resolved, gNB 120 can update the configuration for UE 110 to report at least one QoE measurement based on the corresponding priority configured. For example, gNB 120 can determine the first set of QoE measurements that have been stopped or suspended and update the configuration based on that decision.

[0085] After UE 110 receives 410 to the updated configuration, UE 110 can resume 420 to report the first set of QoE measurements.

[0086] Similarly, for QoE measurements that have been stopped or suspended from reporting, UE 110 can determine whether the results of these QoE measurements should be recorded or discarded based on the corresponding priority of the stopped or suspended QoE measurements.

[0087] Furthermore, when UE 110 determines that the overload condition of gNB 120 has changed, for example, when UE 110 determines that the reporting of the first set of QoE measurements can be resumed, UE 110 can determine whether the historical results of the first set of QoE measurements have been recorded at UE 110. If UE 110 determines that there are recorded historical results of the first set of QoE measurements, then UE 110 can report the recorded historical results to gNB 120.

[0088] In this way, the gNB has the ability to control the configuration of the UE's QoE measurement reports, and the QoE reports of high-priority UEs can be maintained without interruption under low and medium overload conditions.

[0089] Figure 5 A flowchart of an example method 500 for setting priority for QoE according to some example embodiments of the present disclosure is shown. Method 500 can be implemented as follows: Figure 1 The first device 110 shown is implemented therein. For the purposes of discussion, reference will be made to... Figure 1 Let's describe method 500.

[0090] At 510, the first device receives from the second device an indication associated with reporting at least one Quality of Experience (QoE) measurement to be performed at the first device, the indication being generated by the second device based on the corresponding priority of the at least one QoE measurement.

[0091] In some example embodiments, the first device may receive information about the corresponding priority of at least one QoE measurement from the second device.

[0092] In some example embodiments, the first device may receive a configuration for reporting at least one QoE measurement, determined by the second device based on a corresponding priority. This configuration includes an identifier associated with a first group of QoE measurements that do not need to be reported to the second device; or a service type associated with the first group of QoE measurements that do not need to be reported to the second device.

[0093] At 520, the first device determines a report of at least one QoE measurement based on the instruction.

[0094] In some example embodiments, the first device may receive information from the second device regarding the overload level of the channel between the first and second devices, and determine a threshold priority based on the overload level. If the first device determines that the corresponding priority of a first group of QoE measurements in at least one QoE measurement is lower than the threshold priority, the first device may stop or suspend reporting the first group of QoE measurements.

[0095] In some example embodiments, if the first device determines an additional overload level of the channel received from the second device, the first device may determine an additional threshold priority based on the additional overload level.
