In the following description, the terms “terminal device,” “communication device,” “terminal,” “user equipment,” and “UE” may be used synonymously.

[0030] QoE is typically defined for a particular application / service as a parameter used to describe Quality of Service (QoS). QoE measurement reports are essential to ensure good network service. However, in practice, QoE measurement reports may need to be handled under RAN overload.

[0031] From the perspective of RAN overload situations, the Pause / Resume mechanism is standardized for the NR Standalone scenario in Rel-17. To mitigate RAN overload during ongoing QoE sessions, QoE reporting must be able to be temporarily paused and resumed under the control of the gNB. The mechanism in Rel-17 enables QoE measurement collection control in Standalone deployments (MN only). In this way, the UE must buffer QoE report data while waiting for the system overload condition to recover, and the UE does not know how long it will be able to receive a resume command. The NR-enhanced QoE WI in Rel-18 aims to extend QoE measurement capabilities to the NR-Dual Connectivity (DC) scenario. In one valid use case of the NR-DC scenario, one leg (MN leg) may be interrupted by a network node, and another leg (SN leg originating from the DC) may be used to send QoE measurement report data so as to maintain reporting continuity.

[0032] While the NR-DC architecture mitigates reporting issues under certain RAN overload conditions, under other RAN overload conditions where reporting cannot be achieved—for example, when both legs (MN leg and SN leg) in the NR-DC scenario cannot be used to send QoE measurement reporting data—a timely and effective QoE measurement reporting mechanism is still desirable for reporting continuity.

[0033] Embodiments of this disclosure provide a solution for improved QoE measurement reporting. A terminal device receives a message from a first network device indicating that it is suspending QoE reporting to the first network device. The terminal device then sends a message to the first network device requesting an SRB configuration with a second network device. The terminal device then sends the QoE measurement results to the second network device based on the received SRB configuration. As such, a timely and effective QoE measurement reporting mechanism is provided.

[0034] The principles and embodiments of this disclosure are described in detail below with reference to the accompanying drawings. However, it should be noted that these embodiments are provided as examples and are not intended to limit the scope of this application in any way.

[0035] First, reference is made to Figure 1, which shows an exemplary communication system 100 in which embodiments of the present disclosure may be implemented. As shown in Figure 1, the system 100 includes two network devices, such as network device 111 (which may be considered a first network device in this specification) and network device 112 (which may be considered a second network device or further network device in this specification). It should be understood that network device 111 and network device 112 may be used synonymously. In other words, network device 111 may be considered a second network device or further network device, and network device 112 may be considered a first network device. Network devices 111 and 112 may each have one group of antenna ports. Network devices 111 and 112 may each operate using different frequency bands in both DL and UL. In the communication system, "UL" refers to a communication link in the direction from a terminal device to a network device, and "DL" refers to a communication link in the direction from a network device to a terminal device.

[0036] System 100 also includes one or more terminal devices, such as terminal device 120. Terminal device 120 can connect to and communicate with either or both of network devices 111 and 112, in UL and DL, for example wirelessly, depending on the terminal device's location within the cell of network devices 111 and 112. Terminal device 120 may be configured to communicate with the network via one or more TRPs, for example, two TRPs. The two TRPs may be located in the same cell (intra-cell TRP) or in different cells (inter-cell TRP).

[0037] In Figure 1, the number of network devices and terminal devices is for illustrative purposes only and does not imply any limitation. System 100 may include any suitable number of network devices and terminal devices configured to carry out embodiments of the present disclosure. For example, System 100 may include network device 113 (which may be considered a third network device in this specification).

[0038] Communications within the communication system 100 may be conducted in accordance with any suitable communication protocol, including, but not limited to, third-generation (3G), fourth-generation (4G), and fifth-generation (5G) or later cellular communication protocols, wireless local network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11 and similar, and / or any other protocols currently known or planned to be developed in the future. Furthermore, communications may utilize any suitable wireless communication technology, including, but not limited to, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiple (OFDM), Discrete Fourier Transform spread OFDM (DFT-s-OFDM), and / or any other technologies currently known or planned to be developed in the future.

[0039] Hereafter, reference will be made to Figure 2 illustrating the process 200 for QoE measurement reporting continuity according to various embodiments of the present disclosure. For the purposes of discussion, the process 200 will be described with reference to Figure 1. The process 200 may involve terminal devices 120 and network devices 111, 112 as illustrated in Figure 1. It should be understood that any graphic elements, numbers, and captions in these figures are for illustrative purposes only and do not imply any limitation.

[0040] In process 200, after receiving an interruption indication for QoE measurement reporting, terminal device 120 sends an AS measurement report 203 to network device 111 in the wireless access network based on an AS measurement configuration that enables QoE measurement reporting continuity (202), or sends an AS measurement configuration request 203 (202).

[0041] In some embodiments, a request for an AS measurement configuration may be transmitted via an uplink Radio Resource Control (RRC) message. On the network side, network device 111 may transmit an AS measurement configuration to terminal device 120 that enables QoE measurement reporting continuity. Thus, terminal device 120 may receive an AS measurement configuration from network device 111 that enables QoE measurement reporting continuity. In the example, the AS measurement configuration is received via an RRC reconfiguration message. The AS measurement configuration includes an indication that the AS measurement configuration is configured to support QoE measurement reporting continuity.

[0042] For example, terminal device 120 may receive AS measurement configuration from network device 112. In another example, terminal device 120 may receive AS measurement configuration from network devices 111 and 112.

[0043] In some embodiments, an AS measurement configuration enabling QoE measurement reporting continuity may include a measurement event having a threshold configured to trigger an AS measurement report within a time period for the execution of a measurement event determined based on the requirements for QoE measurement reporting continuity, periodic measurements within a time period for the execution of periodic measurements determined based on the requirements for QoE measurement reporting continuity, or a timer causing a terminal device to report available measurement results based on the timer's termination, even if the measurement results do not reach a configured threshold, or any combination thereof.

[0044] In some embodiments, on the network side, network device 111 may send interruption indications for QoE measurement reporting to terminal device 120. Therefore, based on receiving the interruption indications for QoE measurement reporting, terminal device 120 performs measurements based on the AS measurement configuration and generates an AS measurement report. Alternatively, the interruption indications may be received from network device 112.

[0045] In some embodiments, terminal device 120 is in dual connection mode, network device 111 is the master node (MN), and network device 112 is the secondary node (SN). Interruption indications may be received from both network device 111 and network device 112. Alternatively, network device 111 is the SN and network device 112 is the MN.

[0046] In some embodiments, in a scenario where terminal device 120 is in a dual-connection mode with connections to network devices 111 and 112, if one network device interrupts QoE measurement reporting for terminal device 120, it needs to notify the other network device to avoid interruption in the other leg for the sake of QoE reporting continuity. Network device 111 may send an indication to network device 112 that QoE measurement reporting through network device 111 has been interrupted. Alternatively, network device 112 may send an indication to network device 111 that QoE measurement reporting through network device 112 has been interrupted.

[0047] In some embodiments, the terminal device 120 may transmit an AS measurement report or request by determining whether the terminal device 120 is configured with an AS measurement configuration that enables QoE measurement reporting continuity based on receiving an interruption indication for QoE measurement reporting, transmitting an AS measurement report based on the determination that the terminal device 120 is configured with an AS measurement configuration, and transmitting a request for an AS measurement configuration based on the determination that the terminal device 120 is not configured with a measurement configuration.

[0048] Alternatively, terminal device 120 may send an AS measurement report or request based on determining that the amount of buffered data for QoE measurement reporting is greater than or equal to a threshold. On the network side, network device 111 may configure a threshold for causing terminal device 120 to send an AS measurement report based on determining that the amount of buffered data for QoE measurement reporting at terminal device 120 is greater than or equal to a threshold.

[0049] Continuing with the reference to Figure 2, on the network side, network device 111 receives an AS measurement report associated with terminal device 120 (204), or receives a request for an AS measurement configuration to enable QoE measurement reporting continuity for terminal device 120 (204).

[0050] In some embodiments, in a scenario where terminal device 120 is in a dual-connection mode, with network device 111 being the MN and network device 112 being the SN of terminal device 120, network device 111 may transmit information about its overload condition to network device 112 in order to request network device 112 to adjust the continuity of QoE measurement reporting. Alternatively, network device 112 may transmit information about its overload condition to network device 111 in order to request network device 111 to interrupt QoE measurement reporting through network device 112.

[0051] In some embodiments, network device 111 may select network device 112 as the target network device from a plurality of candidate network devices based on the received AS measurement report. For example, network device 111 may select the target network device based on determining that terminal device 120 is in standalone mode. Network device 111 may initiate a dual connection setup procedure with network device 112, and thus network device 112 may be MN and network device 112 may be SN. In another example, in a scenario where terminal device 120 is in dual connection mode, having connections with both network device 111 and network device 112, network device 111 may select the target secondary PSCell for network device 112 and initiate a secondary PSCell change procedure directed to network device 112.

[0052] Continuing with the reference to Figure 2, based on receiving an AS measurement report or request from terminal device 120, network device 111 sends a request 207 to network device 112 to establish an SRB between terminal device 120 and network device 112 (206). In this example, network device 111 may send a request to establish an SRB by sending network device 112 an SN append or SN modification message containing an indication requesting network device 112 to establish an SRB. Thus, network device 112 may receive a request to establish an SRB by receiving an SN append or SN modification message from network device 111.

[0053] For example, when the UE is in standalone mode, network device 111 may initiate a dual connection setup procedure with network device 112 by sending an SN Add message to network 112 to establish an SRB. As another example, in a scenario where terminal device 120 is in dual connection mode, having connections with both network device 111 and network device 112, network device 111 may initiate a secondary PSCell modification procedure toward network device 112 by sending an SN Modification message to establish an SRB.

[0054] Therefore, network device 112 receives a request from network device 111 to establish an SRB for QoE measurement reporting between terminal device 120 and network device 112 (208). Network device 112 sends an SRB configuration 211 for establishing the SRB to network device 111 or terminal device 120 (210). For example, the SRB includes at least one of the existing SRB3, split SRB4, or new SRB5.

[0055] Therefore, network device 111 receives an SRB configuration from network device 112 for establishing an SRB (212). Through transmission (206) and reception (212), network device 111 obtains an SRB configuration for establishing an SRB for QoE measurement reporting for terminal device 120 (205). Network device 111 then transmits the SRB configuration 211 for establishing an SRB to terminal device 120 (214).

[0056] Alternatively, the SRB for QoE measurement reporting is between terminal device 120 and network device 111. Network device 111 may obtain an SRB configuration by determining the SRB configuration for establishing an SRB between network device 111 and terminal device based on receiving an AS measurement report or a request to establish an SRB from network device 112.

[0057] Continuing with the reference to Figure 2, terminal device 120 receives an SRB configuration to establish an SRB for QoE measurement reporting between terminal device 120 and network device 112 (216). In this example, the SRB configuration is received via an RRC reconfiguration message. The terminal device may receive the SRB configuration from network device 111 or network device 112.

[0058] Next, terminal device 120 sends a QoE measurement report to network device 112 via the established SRB (218). On the network side, network device 112 receives the QoE measurement report from terminal device 120 via the established SRB (220).

[0059] Alternatively, terminal device 120 may receive an SRB configuration to establish an SRB for QoE measurement reporting between terminal device 120 and network device 111. Terminal device 120 may then send a QoE measurement report to network device 111 via the established SRB. On the network side, network device 111 may receive a QoE measurement report from terminal device 120 via the established SRB.

[0060] The above process provides a timely and effective QoE measurement reporting mechanism for reporting continuity under various RAN overload conditions. This enhanced QoE measurement reporting continuity can further improve the user experience.

[0061] In some embodiments, in a scenario where terminal device 120 is in a dual-connection mode, with network device 111 being the MN and network device 113 in the wireless access network (as shown in Figure 1) being the SN of terminal device 120, terminal device 120 may receive an interruption indication by receiving one of the interruption indications from network device 111 and another from network device 113 after the other has been received first. Alternatively, terminal device 120 may receive an interruption indication by receiving an interruption indication from one of network device 111 and network device 113 indicating that the QoE measurement report is interrupted through both network device 111 and network device 113.

[0062] In some embodiments, based on the determination that the interruption indication from network device 111 is received after the interruption indication from network device 113 has been received, terminal device 120 may further send an AS measurement configuration request to network device 111.

[0063] In some embodiments, based on the interruption indication from network device 113 determining that the interruption indication was received after it was received from network device 111, terminal device 120 may further send an AS measurement configuration request to network device 113.

[0064] In some embodiments, based on receiving an interruption indication that QoE measurement reporting is interrupted through both network device 111 and network device 113, terminal device 120 may further send an AS measurement configuration request to either network device 111 or network device 113.

[0065] In some embodiments, on the network side, network device 111 may select a target network device based on determining that terminal device 120 is in dual connection mode, and network devices 111 and 113 connect to terminal device 120, interrupting QoE measurement reporting through both network devices 111 and 113.

[0066] In some embodiments, network device 111 may select another network device, for example, network device 112, as the target network device and send a request to network device 112 to establish an SRB. Thus, network device 112 may receive the request to establish an SRB and send an SRB configuration for establishing the SRB to network device 111.

[0067] In some embodiments, in a scenario where terminal device 120 is in a dual-connection mode, and the UE has connections to both network device 111 and network device 112, network device 112 may receive a request from terminal device 120 for an AS measurement configuration that enables QoE measurement reporting continuity. Network device 112 may then send a request for an AS measurement configuration to network device 111.

[0068] The solutions described herein will be explained in detail below with reference to Figures 3, 4, and 5 for the purpose of a clearer understanding.

[0069] Figure 3 shows an example of process 300 for QoE measurement reporting continuity according to some exemplary embodiments of the present disclosure. For clarity, the UE having QoE configuration and reporting capabilities in Figure 3 may be considered as terminal device 120 in Figure 1, MN in Figure 3 may be considered as network device 111 in Figure 1, and SN in Figure 3 may be considered as network device 112 in Figure 1. Process 300 may be implemented in a scenario where terminal device 120 in Figure 1 is in standalone mode, for example, in a scenario where terminal device 120 has a connection only to network device 111 to send QoE measurement reporting data to the network.

[0070] In Figure 3, the UE may be in a standalone state and may have configured QoE measurements. In process 300, the MN (serving gNB) may configure special Event or periodic measurements for the UE dedicated to reporting continuity. More specifically, as shown in Figure 3, for the AS measurement configuration, the MN sends an RRCReconfiguration message to the UE with a special indication added to measConfig (or appLayerMeasConfig) to indicate that it is a special measurement configuration for QoE reporting continuity.

[0071] Furthermore, with the intention of quickly triggering measurement reports, measConfig may include events A1 / A3 / A5 / B1 / B2 with lower thresholds for AS measurement reports. In other words, one lower threshold may be set in Event Ax / Bx measurements dedicated to QoE reporting. It should be understood that instead of a lower threshold, a higher threshold may be used for AS measurement reports depending on the specific scenario. Alternatively, one shorter period may be set in periodic measurements compared to a normal measurement configuration. With respect to Event measurement configurations, the serving gNB may also configure one surplus timer in measConfig for the UE, thereby instructing the UE to report any available measurement results before the timer expires, even if the measurement results do not reach the configured threshold.

[0072] Next, as an example, special measurement reports are enabled only after a pause command has been received. As shown in Figure 3, when a MeasurementReportAppLayler message containing a QoE report container is received from the UE, the MN sends an RRCReconfiguration message containing QoE report Pause to the UE. Then, a special measurement on the UE side is triggered in response to the acquired Pause command, and the UE may send a Measurement Report message containing an AS measurement report (e.g., Event A3 measurement result). Furthermore, as mentioned above, even if the Event measurement result cannot be sent because it does not meet the configured threshold constraint, a Measurement Report message with any available measurement results will be sent to the MN before the configured QoE report timer expires. Alternatively, the UE may send Measurement Report messages periodically according to the periodic measurement configuration.

[0073] As another example, for better network control, special measurement reporting may be enabled when the QoE reporting data size buffered within the UE AS layer is greater than the threshold configured in the network.

[0074] Next, based on the measurement results, the serving gNB sends an Xn / SN Addition Request message to the SN node selected for DC establishment, adding a new indication to the Xn message to request the SN to establish a split SRB4 or a new SRB5 (used directly for QoE reporting to the SN). Specifically, the MN sends an SN Addition Request message to the SN with a request to establish a split SRB4 or a new SRB5.

[0075] In accordance with the received SN Addition Request, the SN node configures either a split SRB4 or a new SRB5 for the UE accordingly. Specifically, the SN sends an SN Addition Request ACK message to the MN containing the split SRB4 or new SRB5 configuration. The MN then forwards the split SRB4 or new SRB5 configuration to the UE via an RRCReconfiguration message, which includes the SN Addition configuration and the split SRB4 or new SRB5 configuration.

[0076] After receiving the relevant SRB configuration, the UE sends an RRCReconfigurationComplete message to the MN. Thus, RACH access between the UE and SN can be achieved, and the UE can send QoE measurement reports to the network via the newly established SN leg for QoE measurement report continuity.

[0077] Process 300 allows the UE's QoE reporting continuity to be implemented by transitioning from a Standalone state to a dual-connected (e.g., NR-DC) state. In this case, Process 300 uses the UE connection to the SN at the DC for QoE measurement reporting, directly transferring application-layer based measurements to the SN. Such an SN addition may be triggered when a UE in a QoE measurement interruption state maintains QoE reporting continuity. This novel mechanism requires RRC and Xn signaling to support standardization.

[0078] Figure 4 shows an example of process 400 for QoE measurement reporting continuity according to some exemplary embodiments of the present disclosure. For the sake of clarity, the UE having QoE configuration and reporting capabilities in Figure 4 may be considered as terminal device 120 in Figure 1, MN in Figure 4 may be considered as network device 111 in Figure 1, T-SN in Figure 4 may be considered as network device 112 in Figure 1, and S-SN in Figure 4 may be considered as network device 113 in Figure 2. Process 400 may be implemented in a scenario in which terminal device 120 in Figure 1 is in dual connection mode, for example, in a scenario in which terminal device 120 has connections to both network device 111 and network device 112 in order to send QoE measurement reporting data to the network. For the sake of brevity, only the differences between process 400 and process 300 are described here, and the same or similar details may be referenced to one another without repetition.

[0079] As shown in Figure 4, the MN may send an RRCReconfiguration message with appLayerMeasConfig for QoE measurement reporting to the UE. The UE may send a MeasurementReportAppLayler message with a QoE reporting container to at least one of the MN and S-SN. In response to the MeasurementReportAppLayler message, the MN may send an RRCReconfiguration message with MN QoE Report Pause to the UE, and the S-SN may send an RRCReconfiguration message with SN QoE Report Pause to the UE. If the UE decides that both legs (the MN leg and the S-SN leg) will be interrupted and no special measurements will be configured, the UE may send an RRCReconfigurationComplete message to the S-SN with a request for special measurements for QoE reporting continuity. Upon receiving the RRCReconfigurationComplete message, the S-SN forwards the request to configure the special measurements to the MN. Subsequently, another connection between the UE and another SN (T-SN leg) may be established for QoE reporting continuity, as illustrated in Figure 3. In addition, the MN may send an S-SN Release Request message to the S-SN, and the S-SN may send an S-SN Release Request ACK message to the MN to optimize the use of network resources.

[0080] In process 400, due to an SN change trigger, the UE is in a DC state, but both legs cannot support QoE reporting. If the UE receives interruption commands from both MN and SN, the special measurement mechanism proposed above may be applied to trigger the SN change procedure for QoE reporting continuity in order to maintain QoE reporting continuity.

[0081] Process 400 allows for the continuity of UE QoE reporting through SN changes. In this case, even if both legs are interrupted at DC, QoE measurement reporting can continue with a newly established leg. This new mechanism also requires RRC and Xn signaling to support standardization.

[0082] It should be understood that when a DC-capable UE receives a QoE Pause command from the network, if the UE already has a measurement configuration for QoE reporting continuity, the UE will enable special measurements and report the measurement results for DC establishment or modification. If the UE does not have a special measurement configuration, a new indication will be added to the uplink RRC message, for example, the RRCReconfigureComplete message, to request the serving gNB to configure special measurements for DC establishment or modification.

[0083] Figure 5 shows an example of process 500 for QoE measurement reporting continuity according to some exemplary embodiments of the present disclosure. For the sake of clarity, the UE having QoE configuration and reporting capabilities in Figure 5 may be considered as terminal device 120 in Figure 1, MN in Figure 5 may be considered as network device 111 in Figure 1, and SN in Figure 5 may be considered as network device 112 in Figure 1. Process 500 can be implemented in a scenario where terminal device 120 in Figure 1 is in dual connection mode, for example, in a scenario where terminal device 120 has connections to both network device 111 and network device 112, but only the connection to network device 111 has an SRB used to send QoE measurement reporting data to the network. For the sake of brevity, only the differences between process 500 and processes 300, 400 are described here, and the same or similar details may be referenced to one another without repetition.

[0084] In process 500, for SN modification, the UE is in a dual-connection state and has configured QoE measurements, but only one connection to the MN or SN has an SRB for sending QoE measurement reports. Both the MN and SN, as serving gNBs, may configure special Event or periodic measurements for the UE dedicated to QoE reporting continuity. A new indication is added to measConfig to indicate that it is a special measurement configuration for QoE reporting continuity (the same conditions may apply with respect to SN additions). The indication may indicate to the UE that it is permitted to report QoE measurement results directly to the SN after receiving an interrupt command from the MN which has an SRB for sending QoE measurement reports, or directly to the MN after receiving an interrupt command from the SN which has an SRB for sending QoE measurement reports. For example, the MN sends an Xn / SN modification message to the SN for modification by a new indication added to the Xn message to request the SN to establish a split SRB4 (used for QoE reporting to the MN through the SN leg) or a new SRB5 (used for QoE reporting directly to the SN). Alternatively, the UE may be allowed to report QoE measurement reports to the SN via the existing SRB3. For this reason, RRC message (MeasurementReportAppLayer) transfer is enabled via SRB3. For example, the SN sends an Xn / SN message to the MN for modification with a new indication added to the Xn message to request the MN to establish SRB4 (used for QoE reporting to the MN). Upon receiving the new indication and the Pause command (to temporarily suspend QoE reporting), the UE sends the QoE report to the network via the newly established SRB (SRB3, split SRB4, or new SRB5 for the SN, or SRB4 for the MN) and the corresponding leg.

[0085] As shown in Figure 5, when the MN receives a MeasurementReportAppLayler message with a QoE reporting container, the MN may send an RRCReconfiguration message to the UE with MN QoE reporting Pause if the UE is in an overloaded state. If the MN leg is interrupted and the UE is operating on DC, the UE may send an RRCReconfigurationComplete message to the MN with a special measurement request for QoE reporting continuity. The MN may then send an SN Modification Request message to the S-SN with a request to establish an SRB for QoE reporting. In response to the received SN modification request, the SN may send an SN Modification Request ACK message to the MN with an SRB3, split SRB4, or new SRB5 configuration. The MN may then send an RRCReconfiguration message to the UE with a special indication for QMC continuity only. In addition, the MN may send an RRCReconfiguration message to the UE with a configuration for QoE reporting and an SRB3, split SRB4, or new SRB5 configuration. If the MN leg is interrupted on the terminal device side and reporting to the SN leg is permitted, the UE sends an RRCReconfigurationComplete message to the MN. Thus, the connection between the UE and the SN is used for QoE measurement reporting continuity, and a MeasurementReportAppLayler message containing the QoE reporting container can be sent from the UE to the SN via the SRB.

[0086] Process 500 allows for the continuity of QoE reporting for a UE to be achieved through SN modification or SN change. In this case, even when the UE is in a DC state, and the MN leg is interrupted and the SN leg cannot be used for QoE measurement reporting, the QoE measurement reporting can continue with a new established SRB having one new SN due to the SN change. This new mechanism also requires RRC and Xn signaling to support standardization.

[0087] In some embodiments, the SN has an SRB for the UE for QoE reporting, but the MN does not. Option 1: The SN configures a special AS measurement configuration for the UE via SRB3 and sends a Pause to the UE. Option 2: The SN sends a Pause to the UE and notifies the MN of the Pause state that the UE QoE reporting was stopped on the SN side. In Option 2, the SN does not configure an AS measurement configuration for the UE. In Option 1: The SN may receive an AS measurement report from the UE via SRB3 and forward it to the MN via Xn, and the MN may establish an SRB4 between the MN and the UE, or, based on the SN's AS measurement report, the MN may select a new SN for QoE continuity between the new SN and the UE (SN change). In Option 2: The SN notifies the MN of the pause state via Xn, and the MN may establish an SRB4 between the MN and the UE, or the MN configures a special AS measurement reconfiguration for the UE, and based on the MN's AS measurement report, the MN selects one new SN for QoE continuity between the new SN and the UE (SN change).

[0088] In some embodiments, Rel-18 provides several options for the interruption mechanism of QoE measurement reports applicable to dual-connection scenarios in the case of QoE in a dual-connection scenario. Option 1 may be that only the MN can send interruption indications related to QoE measurement reports to the terminal device, and the QoE measurement report may be interrupted by a single interruption indication for both connections between the terminal device and both network nodes (MN and SN), or for the connection between the terminal device and the MN, or for the connection between the terminal device and the SN. In Option 1, several interactions may exist between the MN and the SN. Option 2 may be that the MN and the SN can independently send interruption indications related to QoE measurement reports. In Option 2, several interactions may exist between the MN and the SN.

[0089] More specifically, in Option 1, only the MN can interrupt the UE reporting QoE measurements via interruption indications. Through the Xn interface, the MN can notify the SN of its overload condition to request adjustment of the continuity of QoE measurement reporting. Through the Xn interface, the SN can notify the MN of its overload condition to request interruption of QoE measurement reporting through the connection between the SN and the terminal device. Through the Uu interface between the terminal device and the MN, interruption indications associated with QoE measurement reporting may require extensions that may add new indications to show which leg of QoE measurement reporting is interrupted—for MN only, SN only, or both.

[0090] In Option 2, the MN and SN can independently send interruption indicators related to QoE measurement reports. Through the Uu interface, SRB3 can be established via the RRC Configuration procedure to support sending interruption indicators from the SN. Through the Xn interface, if one node has interrupted a QoE measurement report, it can notify other nodes to avoid interruptions in other legs for the sake of QoE reporting continuity. The UE can indicate to the network that it is requesting recovery when interruption indicators have been received from both the MN and SN.
