Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0120] In order to facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical contents related to the embodiments of the present application are first introduced.

[0121] 1. QoE Measurement

[0122] The protocol defines two types of QoE measurements. One is signaling based, in which the operation administration and maintenance (OAM) sends QoE configuration to the core network (CN), the core network sends QoE configuration to the radio access network (RAN), and the RAN forwards the QoE configuration to the UE. In this case, the configuration is for a specific UE. The other is management based, in which the OAM directly sends QoE configuration to the RAN, and the RAN forwards the QoE configuration to the UE. In this case, the configuration is for multiple UEs. In the system framework of the two measurement configurations of signaling based and management based, the process of QoE configuration sent by the RAN to the UE is the same, and the configuration parameters are also the same, and are sent to the UE through radio resource control (RRC) signaling. Signaling based measurements are generally used for measurement collection of specified users, and management based measurements are generally used for measurement collection of specified areas.

[0123] The protocol defines the Quality of Experience (QoE) measurement management parameters, including the following parameters (the following parameters are exemplary and not all are listed):

[0124] a)QoE collection entity address

[0125] This parameter is used to define the Internet Protocol (IP) address to which the QoE Measurement Collection (QMC) records will be transmitted. Either Internet Protocol version 4 (IPv4) or Internet Protocol version 6 (IPv6) addresses can be used.

[0126] b)QoEreference

[0127] This parameter defines the identifier of the network requesting QoE measurement. QoEreference should be globally unique, so it consists of the following: Mobile Country Code (MCC) + Mobile Network Code (MNC) + QMC Identifier (ID), where MCC and MNC come from the management system and are used to define a Public Land Mobile Network (PLMN) included in the management system. The QMC ID is a 3-byte string.

[0128] c)QMC configuration file

[0129] This parameter defines the QoE profile defined by the application layer service.

[0130] d)Service Type

[0131] This parameter defines the service type for which QoE measurement is to be performed, including streaming media, Multimedia Telephony Service for IMS (IP Multimedia Subsystem), MTSI, and Virtual Reality (VR).

[0132] e) Area scope

[0133] In management-based QoE measurement, this parameter defines the scope for collecting QoE measurements.

[0134] After the UE's access stratum (AS) receives the QoE configuration through the RRC message, the AS layer will send the QoE configuration to the application layer through the command defined by the AT (Attention) instruction, including parameters such as service Type, QoEReference, and QMC configuration file. When the service of the service type corresponding to the configuration begins to occur, the application layer begins to measure according to the configuration file and generates a QoE measurement report according to the configuration conditions. Once the QoE measurement report is generated, the UE's application (APP) layer sends the QoE measurement report to the UE's AS layer through the AT command, and the UE's AS layer sends the QoE measurement report to the RAN through the RRC message. The RAN sends the QoE measurement report to the corresponding server corresponding to the IP address defined in the configuration file, thereby completing the QoE configuration and measurement report collection process.

[0135] The base station can also configure the base station visible QoE, that is, RVQoE (RANvisiable QoE), based on the QoE configured by the above OAM. Because the ordinary QoE measurement report is mainly used by OAM and encoded in the format defined by OAM, the base station does not decode the QoE measurement report in principle; if the base station also intends to improve and guarantee QoE, it can configure the UE to report RVQoE, so that the base station can directly receive and use RVQoE.

[0136] 2. QoE reporting

[0137] For the QoE measurement report in the connected state, the UE's APP layer generates the QoE measurement report and directly sends it to the UE's AS layer. The AS layer reports the QoE measurement report directly to the base station through the application layer measurement report (MeasReportAppLayer) message. When the base station side is overloaded, the base station sends a suspend reporting instruction to the UE, and the UE's AS layer temporarily stores the QoE measurement report from the APP layer, and waits for the network side to send a resume reporting instruction, and the UE resumes reporting the QoE measurement report. During the period when the RAN measurement is overloaded, the sending of the RV QoE measurement report is not affected.

[0138] In the QoE measurement of broadcast services, since the UE can continuously receive broadcast services in the connected state, inactive state and idle state, it is necessary to support the UE to perform QoE measurement in the inactive state and idle state. Since the UE cannot directly report the QoE measurement report in the non-connected state, the AS layer of the UE needs to temporarily store the QoE measurement report in the idle state and the inactive state. When the UE returns to the connected state, the QoE measurement report available indication is carried in the completion message (RRCSetupComplete or RRCResumeComplete). When the base station receives the indication information, the QoE measurement report can be obtained.

[0139] 3. NTN Network

[0140] The NTN network is introduced in 5G. UEs supporting the NTN network can connect to the New Radio (NR) network system through the NTN payload (on-board payload) and the NTN Gateway (ground gateway). The main application scenario is that UEs can connect to the NR network via satellite in locations where the NR network coverage is not good to obtain network services, or broadcast services over a large area through the NTN network.

[0141] In the NTN system, two entities, NTN payload and NTN Gateway, are mainly introduced. The link between UE and NTN payload is called service link, and the link between NTN payload and NTN Gateway is called feeder link. NTN payload is generally deployed on satellites or high-altitude aircraft to provide connection between service link and feeder link. NTN Gateway is generally deployed on the surface of the earth to provide feeder link connection with NTN payload. In the NTN system, due to the different operation conditions of satellites at different altitudes, service links are generally divided into three types according to whether the NTN cell is fixed:

[0142] 1) Earth-fixed: Provided by beams that continuously cover the same geographical area, such as geosynchronous orbit satellites (GSO).

[0143] 2) Quasi-Earth-fixed: The beam covers one geographical area for a limited time and another geographical area for another time. For example, non-geosynchronous satellites can generate steering beams.

[0144] 3) Earth-moving: Provided by a beam whose coverage area slides over the surface of the Earth, such as in the case of a non-geosynchronous satellite producing a fixed or non-steerable beam.

[0145] At present, the relevant technologies mainly discuss the scenarios of Quasi-Earth-fixed and Earth-moving. In the relevant technologies, the mobility of UE in idle state and connected state is mainly completed. In idle state, UE is supported to perform cell reselection based on time; in connected state, UE is supported to perform conditional switching based on time and location.

[0146] Unlike the terrestrial network (TN), in the NTN network, the UE needs to connect to the NR network via satellite, and the NTN payload transmits the signaling and data from the UE to the NTN Gateway through the service link, and vice versa. Therefore, this will introduce a relatively large delay compared to the TN network. In addition, in the NTN network, the coverage area of ​​the NTN cell is very large, and a large number of UEs may be included in one NTN cell. Different network types are also defined under the NTN network, such as NR (LEO, Low Earth Orbit), NR (MEO, Middle Earth Orbit), NR (GEO, Geosynchronous Orbit) and NR (OTHERSAT).

[0147] Currently, there is no clear solution for how to report the QoE measurement reports generated after the UE performs QoE measurement in the NTN network.

[0148] Figure 1 A flowchart of a method for reporting a QoE measurement report provided in an embodiment of the present application is provided. The method can be applied to a terminal, such as Figure 1 As shown, the method comprises the following steps:

[0149] Step 100: A terminal in a connected state or a non-connected state generates and stores a first QoE measurement report in a non-terrestrial network NTN network.

[0150] Specifically, the first QoE measurement report refers to a QoE measurement report generated after the terminal performs QoE measurement in the NTN network.

[0151] In an embodiment of the present application, the terminal may perform QoE measurement under the NTN network in a connected state to generate a first QoE measurement report; or, the terminal may perform QoE measurement under the NTN network in a non-connected state (such as an inactive state or an idle state) to generate a first QoE measurement report. For example, the terminal may perform QoE measurement for broadcast services under the NTN network in a non-connected state.

[0152] In some embodiments, the APP layer of the terminal may send the first QoE measurement report to the AS layer of the terminal after generating the first QoE measurement report, and the AS layer of the terminal temporarily stores the first QoE measurement report; or, the APP layer of the terminal may directly cache after generating the first QoE measurement report.

[0153] In some embodiments, when the APP layer of the terminal has a cached first QoE measurement report, the APP layer of the terminal may send a report available indication to the AS layer of the terminal.

[0154] Step 101: In an NTN network or a terrestrial network TN network, a terminal sends an available indication of a first QoE measurement report in a connected state.

[0155] Specifically, when the terminal stores the first QoE measurement report, it can send a QoE measurement report available indication to the network side (RAN side) in a connected state, for example: the terminal can send an available indication of the first QoE measurement report to the network side in a connected state, indicating that the terminal stores the first QoE measurement report. The available indication of the first QoE measurement report can be sent in the NTN network, or can be sent after the terminal reaches the TN network.

[0156] In some embodiments, the QoE measurement report available indication can distinguish between NTN networks and TN networks, that is, the QoE measurement report available indication can be of two types, one type is a QoE measurement report available indication dedicated to the NTN network, which is dedicated to indicating that the QoE measurement report under the NTN network is available; the other type is a QoE measurement report available indication dedicated to the TN network, which is dedicated to indicating that the QoE measurement report under the TN network is available. In this case, the type of the first QoE measurement report available indication is the QoE measurement report available indication dedicated to the NTN network.

[0157] In some embodiments, the QoE measurement report available indication does not distinguish between NTN networks and TN networks, that is, the QoE measurement report available indication is common to NTN networks and TN networks, and can be used to indicate that the QoE measurement report under the NTN network is available, and can also be used to indicate that the QoE measurement report under the TN network is available. In this case, the type of the available indication of the first QoE measurement report can be a general QoE measurement report available indication.

[0158] Step 102: In the NTN network or the TN network, the terminal reports a first QoE measurement report in a connected state.

[0159] Specifically, after the terminal sends an available indication of the first QoE measurement report to the network side, the network side can obtain the first QoE measurement report when needed based on the available indication of the first QoE measurement report, and the terminal can report the stored first QoE measurement report in a connected state under the NTN network or the TN network.

[0160] The QoE measurement report reporting method provided in the embodiment of the present application can send an available indication of the first QoE measurement report through the NTN network or the TN network in a connected state, and then report the stored first QoE measurement report. By providing a QoE measurement report reporting method under the NTN network, the QoE of each service under the NTN network can be effectively improved and guaranteed.

[0161] In some embodiments, sending an indication of availability of the first QoE measurement report includes:

[0162] The availability indication of the first QoE measurement report is sent through a radio resource control RRC message, where the RRC message includes: terminal assistance information, an RRC reconfiguration complete message, an RRC establishment complete message, or an RRC recovery complete message.

[0163] Specifically, the terminal may use an appropriate RRC message in the corresponding scenario to send an available indication of the first QoE measurement report in different scenarios, and this application does not specifically limit this. For example, these RRC messages may include: terminal assistance information (UEAssistanceInformation), RRC reconfiguration complete (RRCReconfigurationComplete) message, RRC setup complete (RRCSetupComplete) message or RRC recovery complete (RRCResumeComplete) message, etc.

[0164] In some embodiments, sending the availability indication of the first QoE measurement report through a radio resource control RRC message includes:

[0165] After the terminal in the connected state generates and stores the first QoE measurement report in the NTN network, it sends an indication of the availability of the first QoE measurement report through terminal auxiliary information in the NTN network; or,

[0166] After the terminal in the connected state generates and stores the first QoE measurement report in the NTN network, when switching from the NTN network to the TN network, the terminal sends an available indication of the first QoE measurement report through an RRC reconfiguration completion message; or,

[0167] After the terminal in the non-connected state generates and stores the first QoE measurement report in the NTN network, when entering the connected state from the non-connected state, the terminal sends an available indication of the first QoE measurement report through an RRC establishment completion message or an RRC recovery completion message.

[0168] For example, the terminal can send an available indication of the first QoE measurement report in the NTN network. If the terminal performs QoE measurement and generates a first QoE measurement report when the terminal is in a connected state in the NTN network, in this case the terminal can directly send an available indication of the first QoE measurement report through a UEAssistanceInformation message.

[0169] For example, the terminal needs to send an available indication of the first QoE measurement report in the TN network. If the terminal performs QoE measurement and generates a first QoE measurement report when it is in a connected state in the NTN network, in this case, the terminal can carry the available indication of the first QoE measurement report in the RRCReconfigurationComplete message when switching to the TN cell.

[0170] For example, when the terminal is in a non-connected state in the NTN network, it performs QoE measurement and generates a first QoE measurement report. In this case, when the terminal enters a connected state (which can be a connected state in the NTN network or a connected state in the TN network) from a non-connected state, it carries an available indication of the first QoE measurement report in an RRCSetupComplete message or an RRCResumeComplete message.

[0171] In some embodiments, sending an indication of availability of the first QoE measurement report includes:

[0172] If it is determined that the public land mobile network PLMN of the cell where the terminal is located is in the PLMN list configured on the network side, an available indication of the first QoE measurement report is sent.

[0173] Specifically, before sending the available indication of the first QoE measurement report, the terminal can check whether the public land mobile network (Public Land Mobile Network, PLMN) of the cell where the terminal is currently located is in the PLMN list configured on the network side. Only when the PLMN of the cell where the terminal is currently located is in the PLMN list configured on the network side, the terminal sends the available indication of the first QoE measurement report. Otherwise, the terminal does not send the available indication of the first QoE measurement report, thereby avoiding waste of network resources.

[0174] In some embodiments, when the terminal enters a connected state (which may be a connected state under an NTN network or a connected state under a TN network) from a non-connected state, the terminal first checks whether the PLMN to which the current cell belongs is in the PLMN list according to the PLMN list in the QoE configuration. If the PLMN to which the current cell belongs is in the configured PLMN list, the terminal may send an available indication of the first QoE measurement report through an RRCSetupComplete message or an RRCResumeComplete message.

[0175] In some embodiments, reporting the first QoE measurement report includes:

[0176] After the network device establishes a signaling radio bearer SRB 4 or SRB 5 for the terminal, an application layer measurement report message is sent to the network device, where the application layer measurement report message includes a first QoE measurement report; or,

[0177] Sending a terminal information response message to the network device according to the terminal information request message sent by the network device, where the terminal information response message includes a first QoE measurement report requested by the network device; or,

[0178] According to the report request message sent by the network device, an application layer measurement report message is sent to the network device, where the application layer measurement report message includes a first QoE measurement report requested by the network device.

[0179] Specifically, after receiving the available indication of the first QoE measurement report sent by the terminal, if the network device (eg, base station) wants to obtain the first QoE measurement report, there are many different ways.

[0180] For example, the network device can directly establish a signaling radio bearer (SRB) 4 or SRB 5 for the terminal (for example, in a dual connectivity (DC) scenario, a secondary cell group (SCG) can establish SRB5 to obtain a QoE measurement report), and the terminal reports the first QoE measurement report saved by the terminal through an application layer measurement report (MeasReportAppLayer) message.

[0181] For example, the network device can send a terminal information request (UEInformationRequest) message to the terminal, and the UEInformationRequest message includes a request indication of the first QoE measurement report. After receiving the UEInformationRequest message, the terminal sends a terminal information response (UEInformationResponse) message to the network device, and the UEInformationResponse message includes the first QoE measurement report requested by the network device.

[0182] For example, the network device may send a report request message to the terminal and establish SRB4 or SRB5 for the terminal. The report request message may be a newly defined report request message for requesting to obtain a QoE measurement report, and the report request message includes a request indication for a first QoE measurement report. After receiving the report request message, the terminal sends the first QoE measurement report requested by the network device to the network device through a MeasReportAppLayer message.

[0183] In some embodiments, the method further comprises:

[0184] After the terminal in the non-connected state generates the second QoE measurement report in the TN network, it enters the NTN network. The terminal continues to store the second QoE measurement report in the NTN network until the terminal reports the second QoE measurement report in the connected state in the TN network, or until the storage time of the second QoE measurement report exceeds the preset time.

[0185] Specifically, the second QoE measurement report refers to the QoE measurement report generated after the terminal performs QoE measurement in the TN network. For example, the network configures the QoE measurement of the broadcast service in the TN network, and the terminal performs the QoE measurement for the broadcast service in the non-connected state in the TN network, and generates a second QoE measurement report, which can be temporarily stored in the AS layer or APP layer of the terminal.

[0186] In this embodiment, after the terminal performs QoE measurement in a non-connected state under a TN network to generate a second QoE measurement report, if the terminal enters the NTN network next, regardless of whether the terminal continues to remain in a non-connected state or returns to a connected state under the NTN network, the terminal continues to save the second QoE measurement report until the terminal returns to a connected state under the TN network, and then reports the second QoE measurement report, or until the terminal stores the second QoE measurement report for more than a preset time (for example, 48 hours), the terminal deletes the stored second QoE measurement report.

[0187] In some embodiments, the first QoE measurement report is stored in a dedicated storage space in the access layer of the terminal for storing QoE measurement reports generated in the NTN network; and / or,

[0188] The first QoE measurement report is stored in a dedicated storage space in the application layer of the terminal for storing QoE measurement reports generated in the NTN network.

[0189] Specifically, considering that the terminal may be maintained in the NTN network for a long time, the first QoE measurement report generated may be relatively large, so memory space (i.e., dedicated storage space) can be reserved separately in the AS layer and / or APP layer for storing the QoE measurement report generated in the NTN network.

[0190] In some embodiments, the first QoE measurement report may be directly stored in a memory space separately reserved for the APP layer, or when the AS layer memory is full, the first QoE measurement report may be stored in a memory space separately reserved for the APP layer.

[0191] In some embodiments, the size of the memory space separately reserved in the AS layer and / or APP layer of the terminal for the QoE measurement report generated in the NTN network may be: 64kB, 128kB, 512kB, etc.

[0192] Figure 2 A schematic diagram of a process flow of a method for obtaining a QoE measurement report provided in an embodiment of the present application, which method can be applied to a first network device, such as Figure 2 As shown, the method comprises the following steps:

[0193] Step 200: Receive an indication of availability of a first QoE measurement report; the first QoE measurement report includes a QoE measurement report generated by a terminal in a connected state or a non-connected state in a non-terrestrial network NTN network.

[0194] Specifically, the first network device may be any network device (eg, a base station), which is not limited in the present embodiment. For example, the first network device may be a network device in an NTN network, or may be a network device in a TN network.

[0195] After generating and storing the first QoE measurement report in the NTN network, the terminal in the connected state or the non-connected state may send an available indication of the first QoE measurement report to the network side in the connected state, so as to report the first QoE measurement report to the network side.

[0196] In some embodiments, the first network device receives an indication of the availability of the first QoE measurement report, including:

[0197] A first network device in an NTN network or a terrestrial network TN network receives an available indication of a first QoE measurement report sent by a terminal in a connected state; or,

[0198] A first network device in a TN network receives a switching request message sent by a source network device, where the switching request message includes an available indication of a first QoE measurement report; the source network device is a network device in an NTN network.

[0199] For example, when the terminal stores the first QoE measurement report, the terminal may send an available indication of the first QoE measurement report to the first network device in a connected state, indicating that the terminal stores the first QoE measurement report. The available indication of the first QoE measurement report may be sent by the terminal in the NTN network, or may be sent after the terminal reaches the TN network.

[0200] For another example, when the terminal stores the first QoE measurement report, the terminal can send an available indication of the first QoE measurement report to the source network device in the NTN network in a connected state, and the source network device sends an available indication of the first QoE measurement report to the first network device in the TN network in a switching request message. When the terminal returns to the TN network connected state, the first network device obtains the first QoE measurement report again.

[0201] In some embodiments, receiving an available indication of a first QoE measurement report sent by a terminal in a connected state includes:

[0202] Receiving an available indication of a first QoE measurement report sent by a terminal in a connected state through a radio resource control RRC message;

[0203] The RRC message includes: terminal assistance information, RRC reconfiguration complete message, RRC establishment complete message or RRC recovery complete message.

[0204] Specifically, the terminal may use appropriate RRC messages in corresponding scenarios to send an available indication of the first QoE measurement report in different scenarios. These RRC messages may include: UEAssistanceInformation, RRCReconfigurationComplete message, RRCSetupComplete message or RRCResumeComplete message, etc.

[0205] For example, the terminal can send an available indication of the first QoE measurement report in the NTN network. If the terminal performs QoE measurement and generates a first QoE measurement report when the terminal is in a connected state in the NTN network, in this case the terminal can directly send an available indication of the first QoE measurement report through a UEAssistanceInformation message.

[0206] For example, the terminal needs to send an available indication of the first QoE measurement report in the TN network. If the terminal performs QoE measurement and generates a first QoE measurement report when it is in a connected state in the NTN network, in this case, the terminal can carry the available indication of the first QoE measurement report in the RRCReconfigurationComplete message when switching to the TN cell.

[0207] For example, when the terminal is in a non-connected state in the NTN network, it performs QoE measurement and generates a first QoE measurement report. In this case, when the terminal enters a connected state (which can be a connected state in the NTN network or a connected state in the TN network) from a non-connected state, it carries an available indication of the first QoE measurement report in an RRCSetupComplete message or an RRCResumeComplete message.

[0208] Step 201: Obtain a first QoE measurement report based on an available indication of a first QoE measurement report.

[0209] Specifically, after receiving the available indication of the first QoE measurement report, the first network device can obtain the first QoE measurement report when needed based on the available indication of the first QoE measurement report, and the terminal can report the stored first QoE measurement report in a connected state under the NTN network or the TN network.

[0210] In some embodiments, obtaining a first QoE measurement report includes:

[0211] Establishing a signaling radio bearer SRB 4 or SRB 5 for the terminal, and then receiving an application layer measurement report message sent by the terminal, where the application layer measurement report message includes a first QoE measurement report; or,

[0212] Sending a terminal information request message to the terminal, and then receiving a terminal information response message sent by the terminal, where the terminal information response message includes a first QoE measurement report requested by the first network device; or,

[0213] A report request message is sent to the terminal, and then an application layer measurement report message sent by the terminal is received, where the application layer measurement report message includes a first QoE measurement report requested by the first network device.

[0214] For example, the first network device can directly establish SRB 4 or SRB 5 for the terminal (for example, in a DC scenario, SCG can establish SRB5 to obtain a QoE measurement report), and the terminal reports the first QoE measurement report saved by the terminal through a MeasReportAppLayer message.

[0215] For example, the first network device can send a UEInformationRequest message to the terminal, and the UEInformationRequest message includes a request indication for the first QoE measurement report. After receiving the UEInformationRequest message, the terminal sends a UEInformationResponse message to the first network device, and the UEInformationResponse message includes the first QoE measurement report requested by the network device.

[0216] For example, the first network device may send a report request message to the terminal and establish SRB4 or SRB5 for the terminal. The report request message may be a newly defined report request message for requesting to obtain a QoE measurement report, and the report request message includes a request indication for the first QoE measurement report. After receiving the report request message, the terminal sends the first QoE measurement report requested by the first network device to the first network device through a MeasReportAppLayer message.

[0217] The method for obtaining a QoE measurement report provided in an embodiment of the present application is such that a first network device can receive an available indication of a first QoE measurement report sent by a terminal in a connected state through an NTN network or a TN network, and obtain the first QoE measurement report stored in the terminal when necessary. By providing a method for obtaining a QoE measurement report under an NTN network, the QoE of various services under the NTN network can be effectively improved and guaranteed.

[0218] The methods provided in the embodiments of the present application are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.

[0219] The following describes the methods provided in the above embodiments of the present application by using examples of specific application scenarios.

[0220] Example 1: Reporting of QoE measurement results in NTN network.

[0221] The network can configure the UE's QoE measurement in the NTN network. Since the QoE measurement report is not time-sensitive, the UE can report the QoE measurement report in the NTN network to the network in the NTN network, or report the QoE measurement report in the NTN network to the network when returning to the TN network.

[0222] Step 1: When the UE is in the connected state of the NTN network or the TN network, the base station sends the QoE measurement configuration for the NTN network in the connected state to the UE through the RRC Reconfiguration message or the RRC Resume message. The configuration information includes NTN network related indication information, PLMN list, service type, configuration container and other information.

[0223] Step 2: When the connected UE starts to perform QoE measurement in the NTN network, the APP layer of the UE sends the generated QoE measurement report (first QoE measurement report) under the NTN network to the AS layer of the UE, and the AS layer of the UE temporarily stores the QoE measurement report under the NTN network.

[0224] Alternatively, when a connected UE starts to perform QoE measurement in the NTN network, the UE's APP layer directly caches the QoE measurement report after generating it. When the UE's APP layer has a cached QoE measurement report in the NTN network, the UE's APP layer sends a report available indication to the UE's AS layer.

[0225] Step 3: If the AS layer or APP layer of the UE stores the QoE measurement report under the NTN network, and the UE has not sent a UEAssistanceInformation message or the sent UEAssistanceInformation does not include an indication that the QoE measurement report under the NTN network is available, the UE triggers the UEAssistanceInformation reporting process, and the UEAssistanceInformation message includes an indication that the QoE measurement report under the NTN network is available. After receiving the indication information, the network can directly obtain the QoE measurement result under the NTN network; or, when the UE returns to the TN network, the QoE measurement report is obtained. At this time, when the UE switches from the NTN cell to the TN cell, the indication that the QoE measurement report under the NTN network is available can be carried in the switching command (switching request message) of the interface.

[0226] Alternatively, if the AS layer or APP layer of the UE stores the QoE measurement report under the NTN network, only when the UE switches to the TN cell, the UE carries the available indication of the QoE measurement report under the NTN network in the RRCReconfigurationComplete message.

[0227] Alternatively, when the UE enters a non-connected state in the NTN network, the UE continues to save the stored QoE measurement report in the NTN network for up to 48 hours. When the UE returns to a connected state in the TN network or the NTN network, the UE checks whether the PLMN to which the current cell belongs is in the PLMN list according to the PLMN list in the QoE configuration. If the PLMN is in the configured PLMN list, the UE reports the available indication of the QoE measurement report in the NTN network in the completion message (RRCSetupComplete message, RRCResumeComplete message).

[0228] Step 4: After the base station receives the indication that the QoE measurement report under the NTN network is available, if the network wants to obtain the QoE measurement report under the NTN network, the base station can directly establish SRB4 or SRB5 for the UE, and the UE reports the QoE measurement report under the NTN network saved by the UE through the MeasReportAppLayer message.

[0229] Alternatively, the base station uses the existing UE information request reporting mechanism to obtain the QoE measurement report under the NTN network: the base station includes a QoE measurement report request indication under the NTN network in the UEInformationRequest message, and after the UE receives the request message, it includes the stored QoE measurement report under the NTN network in the UEInformationResponse message.

[0230] Alternatively, the base station defines a new report request message, in which the base station carries an indication of a request to obtain a QoE measurement report under the NTN network, and establishes SRB4 or SRB5. After the UE receives the report request message, the UE sends the stored QoE measurement report under the NTN network through a MeasReportAppLayer message.

[0231] Example 2: Reporting of QoE measurement results for broadcast services in NTN network.

[0232] Since the UE can receive broadcast services in various states (including: connected state, inactive state and idle state) in the NTN network, in order to collect the user experience of the UE receiving broadcast services in the NTN network, the network can configure the UE to measure the QoE of the broadcast services in the NTN network. The configuration and reporting of the QoE measurement of the broadcast services in the connected state can reuse the method in Example 1. Here, the QoE measurement of the broadcast services in the NTN network in the IDLE state and the INACTIVE state is mainly described.

[0233] Step 1: When the UE is in the connected state of the NTN network or the TN network, the base station sends the QoE measurement configuration for the broadcast service in the NTN network to the UE through the RRCReconfiguration message or the RRCResume message. The configuration information includes NTN related indications, MBS related indications (broadcast services), PLMN list and other QoE related configurations, such as servicetype, configuration container and other information.

[0234] Step 2: When the UE enters the IDLE state or the INACTIVE state, if the UE receives a broadcast service in the NTN network, the UE starts or continues to perform QoE measurement for the broadcast service in the NTN network, and the APP layer of the UE sends the QoE measurement report (the first QoE measurement report) to the AS layer of the UE, and the AS layer of the UE temporarily saves the QoE measurement report in the NTN network.

[0235] Alternatively, the APP layer of the UE directly temporarily stores the QoE measurement report of the broadcast service under the NTN network. When the APP layer of the UE has a cached QoE measurement report under the NTN network, the APP layer of the UE sends a report available indication to the AS layer of the UE.

[0236] Step 3: When the UE returns to the connected state in the TN network or NTN network, the UE checks whether the PLMN to which the current cell belongs is in the PLMN list according to the PLMN list in the QoE configuration. If the PLMN is in the configured PLMN list, the UE carries the available indication of the QoE measurement report of the broadcast service in the NTN network in the non-connected state in the completion message (RRCSetupComplete message, RRCResumeComplete message) and reports it to the network.

[0237] Step 4: After the base station receives the indication that the QoE measurement report of the broadcast service in the NTN network is available, if the network wants to obtain the QoE measurement report of the broadcast service in the non-connected NTN network, the base station can directly establish SRB4 or SRB5 for the UE, and the UE reports the QoE measurement report through the MeasReportAppLayer message.

[0238] Alternatively, the base station obtains the QoE measurement report using the existing UE information request reporting mechanism: the base station includes a QoE measurement report indication of the broadcast service under the NTN network in the UEInformationRequest message. After the UE receives the request message, it includes the stored QoE measurement report of the broadcast service under the non-connected NTN network in the UEInformationResponse message and reports it to the network.

[0239] Alternatively, the base station defines a new report request message. When the network wants to obtain the QoE measurement report of the broadcast service in the non-connected NTN network, the report request message carries an indication of obtaining the QoE measurement report of the broadcast service in the non-connected NTN network, or carries two indications, indicating obtaining the QoE measurement report in the NTN network and indicating obtaining other QoE measurement reports. And establish SRB4 or SRB5 for the UE, and the UE sends the stored QoE measurement report in the non-connected NTN network through the MeasReportAppLayer message.

[0240] Example 3: Processing of QoE measurement reports of broadcast services in TN network in NTN network.

[0241] Since the network is configured with QoE measurement of broadcast services in the TN network, when the UE enters the IDLE state or INACTIVE state, the UE will temporarily store the QoE measurement report (second QoE measurement report) in the AS layer. When the UE enters the NTN network from the TN network in the IDLE state or INACTIVE state, the UE continues to save the non-connected state QoE measurement report in the TN network regardless of whether the UE continues to remain in the non-connected state or returns to the connected state. Only when the UE returns to the connected state in the TN network, the UE informs the network in the completion message that the UE has stored the QoE measurement report of the broadcast service in the TN network.

[0242] Example 4: Memory space processing for storing QoE measurement reports in NTN networks.

[0243] In the related art, 64kB of memory space is reserved at the AS layer for the RAN overload scenario in the connected state. Considering that the UE may be maintained in the NTN network for a long time, the QoE measurement report generated in the NTN network will be relatively large. Therefore, a new memory space can be introduced separately at the AS layer to store the QoE measurement report in the NTN network; or, a new memory space can be introduced at the APP layer to store the QoE measurement report in the NTN network.

[0244] The QoE measurement report generated under the NTN network can be directly stored in the memory space of the APP layer, or when the AS layer memory is full, the QoE measurement report generated under the NTN network can be stored in the memory space of the APP layer.

[0245] The size of the memory space reserved for the QoE measurement report in the NTN network can be: 64kB, 128kB, 512kB, etc.

[0246] The methods and devices provided in the various embodiments of the present application are based on the same application concept. Since the methods and devices solve problems based on similar principles, the implementation of the devices and methods can refer to each other, and the repeated parts will not be repeated.

[0247] Figure 3 A schematic diagram of the structure of a terminal provided in an embodiment of the present application, such as Figure 3 As shown, the terminal includes a memory 320, a transceiver 310 and a processor 300; wherein the processor 300 and the memory 320 may also be arranged physically separately.

[0248] The memory 320 is used to store computer programs; the transceiver 310 is used to send and receive data under the control of the processor 300.

[0249] Specifically, the transceiver 310 is used to receive and send data under the control of the processor 300 .

[0250] Among them, Figure 3 In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically one or more processors represented by processor 300 and various circuits of memory represented by memory 320 are linked together. The bus architecture may also link together various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described in this application. The bus interface provides an interface. The transceiver 310 may be a plurality of components, namely, a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium, which transmission medium includes a wireless channel, a wired channel, an optical cable, and other transmission media. For different user devices, the user interface 330 may also be an interface capable of externally and internally connecting required devices, and the connected devices include but are not limited to a keypad, a display, a speaker, a microphone, a joystick, and the like.

[0251] The processor 300 is responsible for managing the bus architecture and general processing, and the memory 320 can store data used by the processor 300 when performing operations.

[0252] The processor 300 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or a complex programmable logic device (CPLD). The processor may also adopt a multi-core architecture.
