Description

Technical Field

[0002] Quality of experience (QoE) may refer to the subjective feeling of the terminal user on the service performance provided by the mobile network. The terminal device may obtain a QoE measurement report through QoE measurement, and report the QoE measurement report to the network device to reflect the terminal user's recognition of the service performance provided by the mobile network. At present, the implementation process of the network device obtaining the QoE measurement report may be: the terminal device performs QoE measurement based on the QoE measurement configuration, and when the QoE measurement report is generated, requests the network device to transmit the signaling radio bearer (SRB) of the QoE measurement report, so that the terminal device can report the QoE measurement report to the network device through the SRB.

[0003] However, the above method requests the network device to configure SRB for the terminal device after the terminal device generates the QoE measurement report, which may cause the terminal device to be unable to report the QoE measurement report to the network device in time, thereby making it difficult for the network device to obtain the QoE measurement report of the terminal device in time.

[0046] The following explains the terms involved in the embodiments of the present application to facilitate the reader's understanding.

[0047] 1. QoE Measurement

[0048] QoE measurement refers to measuring the user's comprehensive subjective experience of the quality and performance of the service (including effectiveness and availability), that is, measuring the user's experience of using service applications, so that operators can comprehensively evaluate the service quality and performance through QoE measurement results, so that operators can learn about the problems of the service based on the above-mentioned users' comprehensive evaluation results of the service, and make adaptive adjustments to the communication network based on the above-mentioned problems.

[0049] It should be noted that QoE measurement includes: 1.1, signaling-based QoE measurement, and 1.2, management-based QoE measurement. The following describes each in detail:

[0050] 1.1. Signaling-based QoE measurement

[0051] Signaling-based QoE measurement refers to QoE measurement performed on terminal devices with QoE measurement capabilities, and signaling-based QoE measurement can be performed in real time.

[0052] like Figure 1 As shown, the signaling-based QoE measurement process includes the following S101-S108.

[0053] S101. The access stratum (AS) layer of the terminal device sends capability information to the next generation radio access network (NG-RAN) in the fifth generation mobile communication technology (5G) network. Correspondingly, the NG-RAN receives the capability information from the AS layer of the terminal device.

[0054] The capability information is used to indicate that the terminal device has the capability of QoE measurement.

[0055] In a possible implementation manner, the above-mentioned capability information may be capability information (Capability Information) sent by the terminal device to the NG-RAN.

[0056] S102: The operation administration and maintenance (OAM) device sends configuration QoE measurement information to the core network (CN) device. Correspondingly, the CN device receives the configuration QoE measurement information from the OAM device.

[0057] The configured QoE measurement information is used to trigger the CN device to perform QoE measurement configuration.

[0058] In a possible implementation manner, the configured QoE measurement information may be configured QoE measurement (Configure QoE Measurement) information sent by the OAM device to the CN device.

[0059] It should be noted that the above-mentioned configuration QoE measurement information may include a configuration range of QoE measurement and QoE measurement configuration parameters.

[0060] It should be noted that if NG-RAN determines that the terminal device does not have the ability to measure QoE based on the capability information, the OAM device will also send the configuration QoE measurement information to the CN device. In other words, if NG-RAN determines that the terminal device does not have the ability to measure QoE based on the capability information, S102-S103 will continue to be executed, but S104-S108 will no longer be executed.

[0061] S103, the CN device sends activation QoE measurement information to the NG-RAN. Correspondingly, the NG-RAN receives the activation QoE measurement information from the CN device.

[0062] The activated QoE measurement information includes QoE measurement configuration parameters.

[0063] In a possible implementation manner, the activation QoE measurement information may be activation QoE measurement (Activate QoE Measurement) information sent by the CN device to the NG-RAN.

[0064] It should be noted that after receiving the configuration QoE measurement information from the OAM device, the core network device generates activation QoE measurement information according to the configuration QoE measurement information.

[0065] S104, NG-RAN sends radio resource control information 1 to the AS layer of the terminal device. Correspondingly, the AS layer of the terminal device receives the radio resource control information 1 from NG-RAN.

[0066] The radio resource control information 1 includes QoE measurement configuration parameters.

[0067] It should be noted that the radio resource control information 1 is sent from the NG-RAN to the terminal device in the form of radio resource control signaling.

[0068] In a possible implementation, the radio resource control information 1 may be a radio resource control (RRC) message 1 sent by the NG-RAN to the access layer of the terminal device.

[0069] Optionally, NG-RAN can generate wireless resource control information to be sent to the AS layer of the terminal device based on the QoE measurement configuration parameters included in the activated QoE measurement information and the QoE measurement parameters required by itself, so that the terminal device can perform measurements based on the above two QoE measurement parameters. In this way, the QoE measurement report generated by the terminal device can be used for both OAM optimization and NG-RAN optimization.

[0070] S105, the AS layer of the terminal device sends the mobile terminal command 1 to the application (APP) layer of the terminal device. Correspondingly, the APP layer of the terminal device receives the mobile terminal command 1 from the AS layer of the terminal device.

[0071] Among them, the mobile terminal command 1 includes QoE measurement configuration parameters.

[0072] In a possible implementation manner, the mobile terminal command 1 may be an access termination command (Access Terminate command) 1.

[0073] S106, the terminal device APP layer sends the mobile terminal command 2 to the terminal device AS layer. Correspondingly, the terminal device AS layer receives the mobile terminal command 2 from the terminal device APP layer.

[0074] Among them, the mobile terminal command 2 includes a QoE measurement report.

[0075] S107, the AS layer of the terminal device sends the radio resource control information 2 to the NG-RAN. Correspondingly, the NG-RAN receives the radio resource control information 2 from the AS layer of the terminal device.

[0076] The radio resource control information 2 includes a QoE measurement report.

[0077] In a possible implementation, the radio resource control information 2 may be RRC Message 2 sent by the AS layer of the terminal device to the NG-RAN.

[0078] S108. NG-RAN sends a QoE measurement report to a terminal control element (TCE) / media access control element (MCE). Correspondingly, TCE / MCE receives the QoE measurement report from NG-RAN.

[0079] In a possible implementation, the QoE measurement report may be a QoE measurement report (QoE Report) sent by NG-RAN to TCE / MCE.

[0080] The above describes in detail the process of QoE measurement based on signaling. The following describes in detail the process of QoE measurement based on management.

[0081] 1.2 Management-based QoE Measurement

[0082] Management-based QoE measurement refers to the QoE measurement performed on all terminal devices connected to a specific NG-RAN, and management-based QoE measurement is mostly used in the post-processing stage (i.e., the next stage after the pre-processing stage is completed). Among them, the specific NG-RAN is the access network device connected to the terminal device with QoE measurement capability.

[0083] In a possible implementation manner, the preprocessing stage may be a stage in which the terminal device performs signaling-based QoE measurement.

[0084] like Figure 2 As shown, the management-based QoE measurement process includes the following S201-S207.

[0085] S201. The AS layer of the terminal device sends capability information to the NG-RAN. Correspondingly, the NG-RAN receives the sending capability information from the AS layer of the terminal device.

[0086] It should be noted that S201 is similar to the above-mentioned S101 and can be understood by referring to the above-mentioned S101, which will not be repeated here.

[0087] S202: The OAM device sends activation QoE measurement information to the NG-RAN. Correspondingly, the NG-RAN receives the activation QoE measurement information from the OAM device.

[0088] The activated QoE measurement information carries QoE measurement configuration parameters.

[0089] In a possible implementation manner, the activation QoE measurement information may be activation QoE measurement (Activate QoE Measurement) information sent by the OAM device to the NG-RAN.

[0090] It should be noted that the difference between S202 and the above S102 is that: S202 can directly send activation QoE measurement information from the OAM device to the NG-RAN; while S102 requires the OAM device to first send configuration QoE measurement information to the core network device, and then the core network device generates activation QoE measurement information based on the configuration QoE measurement information, and sends the activation QoE measurement information to the NG-RAN. Since management-based QoE measurement does not require the core network device to relay information, the activation QoE measurement information can be sent directly from the OAM device to the NG-RAN.

[0091] S203, NG-RAN sends radio resource control information 1 to the AS layer of the terminal device. Correspondingly, the AS layer of the terminal device receives the radio resource control information 1 from NG-RAN.

[0092] It should be noted that S203 is similar to the above S104 and can be understood by referring to the above S104, which will not be described in detail here.

[0093] S204, the AS layer of the terminal device sends the mobile terminal command 1 to the APP layer of the terminal device. Correspondingly, the APP layer of the terminal device receives the mobile terminal command 1 from the AS layer of the terminal device.

[0094] It should be noted that S204 is similar to the above-mentioned S105, and can be understood by referring to the above-mentioned S105, which will not be repeated here.

[0095] S205, the terminal device APP layer sends the mobile terminal command 2 to the terminal device AS layer. Correspondingly, the terminal device AS layer receives the mobile terminal command 2 from the terminal device APP layer.

[0096] It should be noted that S205 is similar to the above-mentioned S106, and can be understood by referring to the above-mentioned S106, which will not be repeated here.

[0097] S206. The AS layer of the terminal device sends the radio resource control information 2 to the NG-RAN. Correspondingly, the NG-RAN receives the radio resource control information 2 from the AS layer of the terminal device.

[0098] It should be noted that S206 is similar to the above S107 and can be understood by referring to the above S107, which will not be repeated here.

[0099] S207, NG-RAN sends a QoE measurement report to TCE / MCE. Correspondingly, TCE / MCE receives the QoE measurement report from NG-RAN.

[0100] It should be noted that S207 is similar to the above-mentioned S108, and can be understood by referring to the above-mentioned S108, which will not be repeated here.

[0101] 2. Reporting Process of QoE Measurement Report

[0102] In the RRC reconfiguration process, the network device may send QoE configuration information to the terminal device so that the terminal device performs QoE measurement. After the terminal device performs QoE measurement, it may send a QoE measurement report to the network device when in a connected state.

[0103] like Figure 3 As shown, the process of the terminal device reporting the QoE measurement report includes the following S301-S302.

[0104] S301. Establish RRC reconfiguration between the terminal device and the network device.

[0105] In a possible implementation, the RRC reconfiguration established between the terminal device and the network may be established through RRC reconfiguration information between the terminal device and the network device.

[0106] S302: The terminal device sends a QoE measurement report to the network device. Correspondingly, the network device receives the QoE measurement report from the terminal device.

[0107] In a possible implementation, the QoE measurement report may be an application layer measurement report (Measurement Report App Layer) sent by the terminal device to the network device.

[0108] It should be noted that the RRC state transition mechanism of the terminal device in NG-RAN is: when an RRC connection is established between the terminal device and the network device, the terminal device is in the RRC connected state (also referred to as the connected state) or the RRC inactive state (also referred to as the inactive state). When an RRC connection is not established between the terminal device and the network device, the terminal device is in the RRC idle state (also referred to as the idle state).

[0109] like Figure 4 As shown, Figure 4 The figure shows the RRC state transition process of the terminal device in NG-RAN. The terminal device can be released from the connected state to the inactive state with suspension (Release with Suspend), and then released from the inactive state to the idle state, or directly released from the connected state to the idle state. Alternatively, the terminal device can resume (Resume) from the inactive state to the connected state, or re-establish (Establish) the RRC connection from the idle state and convert to the connected state.

[0110] In a possible implementation, the above-mentioned connected state can be represented by NR RRC_CONNECTED, the above-mentioned inactive state can be represented by NR RRC_INACTIVE, and the above-mentioned idle state can be represented by NR RRC_IDLE.

[0111] 3. RRC connection establishment process of terminal equipment

[0112] like Figure 5 As shown, the implementation process of the terminal device re-establishing a new RRC connection from the idle state to the connected state, or the terminal device recovering from the inactive state to the connected state can be: the terminal device sends an RRC establishment request message to the network device. Correspondingly, the network device receives the RRC establishment request message from the terminal device and establishes an RRC connection for the terminal device. The terminal device sends an RRC establishment completion message to the network device.

[0113] In a possible implementation, the RRC setup request information may be an RRC setup request (RRC Setup Request) sent by the terminal device to the network device. The RRC setup completion information may be an RRC setup completion (RRC Setup Complete) sent by the terminal device to the network device.

[0114] IV. RRC connection release process of terminal equipment

[0115] like Figure 6 As shown, the terminal device initiates the RRC connection release process through the network device, so that the network device instructs the terminal device to switch from the connected state to the idle state or the inactive state.

[0116] In a possible implementation, the implementation process of the RRC connection release of the terminal device is as follows: the network device sends RRC release information to the terminal device. Correspondingly, the terminal device receives the RRC release information from the network device.

[0117] In a possible implementation, the above-mentioned RRC release information may be an RRC release (RRC Release) sent by the network device to the terminal device.

[0118] 5. RRC connection recovery process of terminal equipment

[0119] The RRC connection recovery process of the terminal device is used to restore the suspended RRC connection, that is, to restore the terminal device in the idle state or inactive state to the connected state.

[0120] like Figure 7 As shown, the RRC connection recovery process of the terminal device includes the following S701 to S703.

[0121] S701, the terminal device sends RRC recovery request information to the network device. Correspondingly, the network device receives the RRC recovery request information from the terminal device.

[0122] In a possible implementation, the RRC resume request information may be an RRC Resume Request sent by the terminal device to the network device. The RRC resume request information may also be an RRC Resume Request1 sent by the terminal device to the network device.

[0123] S702: The network device sends RRC recovery information to the terminal device. Correspondingly, the terminal device receives the RRC recovery information from the network device.

[0124] In a possible implementation, the above-mentioned RRC recovery information may be RRCResume sent by the network device to the terminal device.

[0125] S703: The terminal device sends recovery response information to the network. Correspondingly, the network receives the recovery response information from the terminal device.

[0126] Among them, the recovery response information is used to confirm that the terminal device has restored the RRC connection.

[0127] In a possible implementation, the above-mentioned recovery response information may be an RRC recovery completion (RRC Resume Complete) sent by the terminal device to the network device.

[0128] 6. Process of reporting UE Assistance Information (UAI) by terminal equipment

[0129] like Figure 8 As shown, after the RRC reconfiguration is completed, the terminal device can send UAI to the network. Correspondingly, the network receives the UAI from the terminal device.

[0130] In one possible implementation, the terminal device reports UAI to the network device, which allows the network device to determine the state of the terminal device, and then the network device can schedule resources for the terminal device to better match the state of the terminal device, thereby saving power of the terminal device.

[0131] 7. QoE measurement process under multicast and broadcast service (MBS)

[0132] MBS supports QoE measurement in a connected state (CONNECTED state), an inactive state (INACTIVE state), and an idle state (IDLE state). The implementation process of the QoE measurement in the MBS may include the following steps 1 to 5.

[0133] Step 1: When the terminal device is in a connected state, the network device sends the QoE configuration information related to the MBS broadcast service to the terminal device. Correspondingly, the terminal device receives the QoE configuration information from the network device.

[0134] Step 2: When the terminal device switches from the connected state to the idle state or the inactive state, the terminal device performs QoE measurement related to the MBS broadcast service based on the QoE configuration information and generates a QoE measurement report. The terminal device stores the QoE measurement report.

[0135] Step 3: When the terminal device recovers from the idle state or the inactive state to the connected state, the terminal device sends indication information to the network device. Correspondingly, the network device receives the indication information from the terminal device.

[0136] The indication information is used to indicate that the terminal device has generated a QoE measurement report in an idle state or an inactive state.

[0137] In one possible implementation, the indication information sent by the terminal device to the network device may be carried in the RRC Resume Complete or RRC Setup Complete sent by the terminal device to the network device.

[0138] Step 4: The network device configures SRB for the terminal device.

[0139] Exemplarily, the SRB may include SRB4 or SRB5. Different SRBs may carry different data.

[0140] Step 5: The terminal device sends a QoE measurement report to the network device via a radio bearer. Correspondingly, the network device receives a QoE measurement report generated by the terminal device in an idle state or an inactive state via a radio bearer.

[0141] 8. Radio Bearer

[0142] A radio bearer is a channel used to carry data or signaling transmission. The above radio bearers can be divided into SRBs and data radio bearers (DRBs). Among them, SRBs are used to carry signaling transmission, and DRBs are used to carry data transmission.

[0143] In an optional example, the SRBs may include: SRB1, SRB3, SRB4, and SRB5. Different SRBs carry different data, so the different SRBs are described below respectively.

[0144] Among them, SRB1 can be used to transmit data between the terminal device and the master node (MN) (recorded as data #1). Generally, the above data may include new air interface radio resource control measurement report (NR RRC measurement report), radio resource control reconfiguration complete (RRC reconfiguration complete) information, user equipment assistance information (UE assistance information), failure information (failure information), etc. The above data #1 has a higher priority.

[0145] SRB3 can be used to transmit data (recorded as data #2) between the terminal device and the secondary node (SN). Generally, the above data may include failure information of the new radio interface master cell group (NR MCG failure information), etc. The above data #2 has a higher priority.

[0146] Both SRB4 and SRB5 can be used to transmit QoE measurement reports.

[0149] 4.5.1 Activation of measurement collection job and reporting of collected information in NR

[0150] Management Based Activation enables collection of application layermeasurements from the UEs in the specified area for specified end userservice type.

[0151] The parameters for the network request session are sent from the MnS Consumer via the management system to the gNBs that host the cells that are included in the QoE MeasurementCollection job request in the Create MOIQMC operation

[15] . A QMC Job is activated by creating a QMCJob object instance in the MnS producer.

[0154] Figure 4.6.1.2-1 and the text below describe the activation of QoEmeasurement collection before UEregistration procedure to the network.

[0155] The AMF receives and stores QoE measurement collection job which includes as part of API: Numd_SDM.Then the same procedure for activation of measurement collection job is applied asafter completion of UE registration procedure,except that instead of UEContext Modification Request the message Initial Context Setup Request issent,see 4.6.1.1.

[0156] It should be noted that the description of the above 4.5.1-1, 4.6.1.2-1, and activation of QoE measurement collection can be understood by referring to the description of the 3GPP protocol, which will not be repeated here.

[0157] The above is a brief introduction to some concepts involved in the embodiments of this application.

[0158] QoE can refer to the subjective feeling of the terminal user on the service performance provided by the mobile network. The terminal device can obtain a QoE measurement report (also called an application layer measurement report) through QoE measurement (also called application layer measurement), and report the QoE measurement report to the network device to reflect the terminal user's recognition of the service performance provided by the mobile network, and further reflect the gap between the actual network performance and the network performance expected by the user. The terminal device can report the above QoE measurement report to the network device so that the operator can optimize the mobile network according to the QoE measurement report.

[0159] At present, the implementation process of a network device obtaining a QoE measurement report can be as follows: the terminal device receives the QoE configuration information from the network device when it is in a connected state, and performs QoE measurement when it is in an idle state or an inactive state to obtain a QoE measurement report. When the terminal device returns to a connected state, the terminal device sends an indication message that a QoE measurement report has been generated to the network device, so that the network device configures SRB for the terminal device. The terminal device can report the QoE measurement report to the network device through SRB.

[0160] However, if the terminal device is in an idle or inactive state, and QoE measurement is performed but a QoE measurement report has not been generated, then when the terminal device returns to a connected state, the terminal device cannot instruct the network device to configure SRB for the terminal device. In this way, when the terminal device generates a QoE measurement report, it is necessary to re-instruct the network device to configure SRB for the terminal device, resulting in the terminal device being unable to report the QoE measurement report to the network device in a timely manner, and further resulting in the network device being unable to obtain the QoE measurement report of the terminal device in a timely manner.

[0161] In view of this, an embodiment of the present application provides an information transmission method, wherein a first network device obtains first indication information and sends second indication information to a terminal device. That is to say, when the terminal device has triggered QoE measurement, the first network device configures a wireless bearer for the terminal device, so that after the subsequent terminal device completes the QoE measurement, the QoE measurement report obtained by the QoE measurement can be promptly reported to the first network device through the wireless bearer, so that the first network device can obtain the QoE measurement report in a timely manner.

[0162] The technical solution provided in the embodiments of the present application can be applied to various communication systems, for example, a new radio (NR) communication system using 5G, a future evolution system, or a multi-communication fusion system.

[0163] For example, Fig. 9 As shown, Fig. 9 The structure diagram of a communication system provided in an embodiment of the present application is shown. The communication system 90 includes: a first network device 901 and a terminal device 902. Fig. 9 The following description is given by taking an example where a communication system includes a first network device 901 and a terminal device 902 .

[0164] The first network device 901 is used to obtain first indication information and send second indication information to the terminal device 902.

[0165] The terminal device 902 is used to receive the second indication information from the first network device 901.

[0166] The first indication information is used to indicate that the terminal device has triggered the QoE measurement. The second indication information is used to indicate the radio bearer. The radio bearer is used to transmit the QoE measurement report.

[0167] In one example, the first network device 901 is a device located at the access network side of the above-mentioned communication system 90 and having a wireless transceiver function or a chip or chip system that can be set in the device. The first network device 901 includes, but is not limited to: an access point (AP) in a WiFi system, such as a home gateway, a router, a server, a switch, a bridge, etc., an evolved NodeB (eNB), a radio network controller (RNC), a NodeB (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved NodeB, or home NodeB, HNB), a base band unit (BBU), a wireless relay node, a wireless backhaul node, a transmission point (TRP or TP), etc., and can also be a 5G base station, such as a gNB in ​​an NR system, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (DU), a road side unit (road side DU) with a base station function. The first network device 901 also includes base stations in different networking modes, such as a master evolved NodeB (MeNB), a secondary eNB (SeNB, or a secondary gNB (SgNB). The first network device 901 also includes different types, such as ground base stations, air base stations, and satellite base stations.

The terminal device 902 is also called user equipment (UE), mobile station (MS), mobile terminal (MT), and terminal, etc., and is a device that provides voice and / or data connectivity to users. For example, the terminal device 902 includes a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, the terminal device 902 can be: a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), a vehicle-mounted device (such as a car, a bicycle, an electric car, an airplane, a ship, a train, a high-speed train, etc.), a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a smart home device (such as a refrigerator, a TV, an air conditioner, an electric meter, etc.), an intelligent robot, a workshop device, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, a flying device (such as an intelligent robot, a hot air balloon, a drone, an airplane), etc. In one possible application scenario of the present application, the terminal device is a terminal device that often works on the ground, such as a vehicle-mounted device.

[0169] Optionally, the terminal device 902 may be an embedded communication device or a user's handheld communication device, including a mobile phone, a tablet computer, etc.

[0170] As an example, in an embodiment of the present application, the terminal device 902 may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include devices that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0171] In a possible implementation, the communication system 90 may further include a core network device. Exemplarily, the core network device may be a CN or a 5G core network (5G Core, 5GC).

[0189] In order to solve the problems existing in the above-mentioned prior art, the embodiment of the present application proposes an information transmission method, which can obtain the QoE measurement report in time. Fig.11 As shown, the method includes:

[0190] S1101. A first network device obtains first indication information.

[0191] The first indication information is used to indicate that the terminal device has triggered QoE measurement.

[0192] In some possible implementations, the implementation process of S1101 may be: the first network device may obtain the first indication information from the core network device side.

[0193] It should be noted that the core network device stores the QoE measurement information of the terminal device. Therefore, when the terminal device has received the QoE measurement configuration or the terminal device has generated a QoE measurement report, the core network device can determine whether the terminal device has received the QoE measurement configuration or whether the terminal device has generated a QoE measurement report, and then determine whether the terminal device has a configuration or a report. The core network device can send fourth indication information to the first network device to indicate that the terminal device has a configuration or a report, so that the first network device can obtain the first indication information, and then the first network device can configure a wireless bearer for the terminal device.

[0194] In some other possible implementations, the implementation process of S1101 may be: the terminal device sends the first indication information to the first network device. Correspondingly, the first network device receives the first indication information from the terminal device.

[0195] In a possible embodiment, the first indication information is carried in an RRC resume complete message (RRC ResumeComplete message), or the first indication information is carried in an RRC setup complete message (RRC Setup Complete message), or the first indication information is carried in UAI.

[0196] In a possible implementation, the first network device receives fifth indication information from the terminal device, and sends sixth indication information to the terminal device. The terminal device receives the sixth indication information from the first network device, and sends an RRC Resume Complete message, or an RRC SetupComplete message, or a UAI carrying the first indication information to the network device. The fifth indication information is used to request the first network device to establish an RRC connection with the terminal device. The sixth indication information is used to instruct the first network device to establish an RRC connection with the terminal device.

[0197] It should be noted that the above-mentioned RRC Resume Complete message can be triggered when the terminal device recovers from an inactive state to a connected state (that is, triggered in the RRC connection recovery process of the terminal device). The RRC SetupComplete message can be triggered when the terminal device re-establishes a connected state from an idle state (that is, triggered in the RRC connection establishment process of the terminal device). UAI can be triggered when the terminal device completes the RRC connection with the first network device (triggered in the process of the terminal device reporting UAI).

[0198] In one possible implementation, since the terminal device performs QoE measurement and obtains a QoE measurement report in an idle state or an inactive state, when the terminal device recovers from an inactive state to a connected state or re-establishes a connected state from an idle state or the terminal device completes RRC reconfiguration, the first indication information sent to the first network device can be carried in the above-mentioned RRC Resume Complete message, RRC Setup Complete message, or UAI, that is, the first network device can determine whether the terminal device has received the QoE measurement configuration to perform QoE measurement or whether the terminal device has generated a QoE measurement report, so that the first network device can configure a wireless bearer for the terminal device when the terminal device performs QoE measurement or generates a QoE measurement report.

[0199] In a possible implementation, after the RRC connection is completed between the terminal device and the first network device, the terminal device may send the above UAI to the first network device. The first network device receives the above UAI and determines the capabilities of the terminal device at a specific time, so that the first network device can better configure resources for the terminal device, and then better match the capabilities of the terminal device at the characteristic time, so as to achieve the purpose of saving power resources of the terminal device.

[0200] In the embodiment of the present application, the terminal device has triggered QoE measurement, which can be understood as: the terminal device has received the QoE measurement configuration and has not performed QoE measurement, the terminal device is currently performing QoE measurement and has not generated a QoE measurement report, and the terminal device has generated a QoE measurement report; the QoE measurement configuration is used to trigger the terminal device to perform QoE measurement.

[0201] It can be understood that, compared with the general technology of requesting the network device to configure a wireless bearer for the terminal device after the terminal device generates a QoE measurement report, the first network device can configure a wireless bearer for the terminal device when the terminal device has received the QoE measurement configuration and has not performed QoE measurement, or the terminal device is currently performing QoE measurement and has not generated a QoE measurement report, or the terminal device has generated a QoE measurement report. This can avoid the situation where the terminal device is unable to report the QoE measurement report to the first network device in a timely manner.

[0202] Specifically, when the terminal device has been triggered to perform QoE measurement and the terminal device has not generated a QoE measurement report, the terminal device has the ability to perform QoE measurement. Therefore, the terminal device can perform QoE measurement and generate a QoE measurement report. Then, the terminal device can request the first network device to establish a wireless bearer for the terminal device, so that after the terminal device generates the QoE measurement report, it can directly report the QoE measurement report to the first network device through the wireless bearer.

[0203] In the case where the terminal device has received the QoE measurement configuration and has not performed QoE measurement, the terminal device has the ability to perform QoE measurement, so the terminal device can perform QoE measurement and generate a QoE measurement report, and then the terminal device can request the first network device to establish a wireless bearer for the terminal device, so that after the terminal device generates the QoE measurement report, it can directly report the QoE measurement report to the first network device through the wireless bearer. In the case where the terminal device has generated a QoE measurement report, the terminal device has completed the QoE measurement, so the terminal device can request the first network device to establish a wireless bearer for the terminal device, so that the terminal device can report the QoE measurement report to the first network device through the wireless bearer.

[0204] In a possible implementation, before the first network device obtains the first indication information, the second network device may send a QoE measurement configuration to the terminal device. Accordingly, the terminal device receives the QoE measurement configuration from the second network device, so that the terminal device performs QoE measurement based on the QoE measurement configuration.

[0205] Exemplarily, the QoE measurement configuration may include at least one of the following: an access point for sending a QoE measurement report, a format for sending a QoE measurement report, or an interval for sending a QoE measurement report. The QoE measurement configuration may also include other information (e.g., the description in Section 10.5 of 3GPP protocol 26.247), and this application does not impose any limitation on this.

[0206] In a possible implementation, the QoE measurement configuration may be configured in an extensible markup language (XML) format.

[0207] As an example, the first indication information may also include at least one of the following: 1-bit information QoE configuration information indication (TRUE or FALSE), QoE configuration ID (RRC ID or Reference) of the terminal device, session start or end (Session start / stop) indication, service type indication (for example, VR / streaming / MTSI / MBS), IDLE / INACTIVE QoE configuration indication, master communication equipment (MCE) network protocol (internet protocol, IP) indication, or area scope indication. The above is only an exemplary description of the first indication information. The first indication information may also include other information (for example, other information that may indicate that the terminal device has received the QoE measurement configuration), and this application does not impose any restrictions on this.

[0208] In a possible embodiment, the QoE measurement configuration is configured by the second network device for the terminal device.

[0209] It should be noted that the second network device may be the same network device as the first network device, or may be a network device different from the first network device.

[0210] S1102: The first network device sends second indication information to the terminal device. Correspondingly, the terminal device receives the second indication information from the first network device.

[0211] The second indication information is used to indicate a radio bearer, and the radio bearer is used to transmit a QoE measurement report.

[0212] As a possible implementation manner, the implementation process of the first network device receiving the QoE measurement report from the terminal device through the wireless bearer can be: when the terminal device has generated the QoE measurement report, the terminal device can send the QoE measurement report to the first network device through the wireless bearer. Correspondingly, the first network device receives the QoE measurement report from the terminal device through the wireless bearer.

[0213] As a possible implementation method, the implementation process of the first network device obtaining the configuration or report through the wireless bearer can be: the first network device can determine through the wireless bearer whether the terminal device has received the QoE measurement configuration, whether the terminal device has performed the QoE measurement, and whether the terminal device has generated a QoE measurement report, and determine the configuration or report of the terminal device.

[0214] As an example, the above-mentioned radio bearer may be a signaling radio bearer, i.e., SRB. Since SRB4 or SRB5 may be used to transmit QoE-related data (e.g., configuration or report and QoE measurement report), the first network device may configure SRB4 or SRB5 for the terminal device so that the first network device may obtain the configuration or report and QoE measurement report through SRB4 or SRB5.

[0215] It should be noted that, since the above-mentioned wireless bearer is used to transmit the QoE measurement report, if the first network device does not configure the wireless bearer for the terminal device, the terminal device cannot report the QoE measurement report to the first network device, that is, if the first network device does not configure the wireless bearer for the terminal device performing the QoE measurement, the terminal device cannot report the above-mentioned QoE measurement report to the first network device in a timely manner after obtaining the QoE measurement report, thereby making it impossible for the first network device to obtain the QoE measurement report of the terminal device in a timely manner. Based on this, the first network device configures a wireless bearer for the terminal device performing the QoE measurement (i.e., the terminal device that has received the QoE measurement configuration), so that the terminal device can report the above-mentioned QoE measurement report to the first network device in a timely manner after obtaining the QoE measurement report.

[0216] In the information transmission method provided in the embodiment of the present application, the first network device obtains first indication information and sends second indication information to the terminal device. That is to say, when the terminal device has triggered the QoE measurement, the first network device configures a wireless bearer for the terminal device, so that after the subsequent terminal device completes the QoE measurement, it can report the QoE measurement report obtained by the QoE measurement to the first network device in a timely manner through the wireless bearer, so that the first network device can obtain the QoE measurement report in a timely manner.

[0217] The following describes in detail the RRC Resume Complete message, RRC Setup Complete message, UAI, and 3GPP protocol update in the above embodiment.

[0218] As an example, the RRC Resume Complete message may be:

[0225] Specifically, appLayerMeasConfigAvailable can be an available configuration for the application layer, that is, appLayerMeasConfigAvailable can be used to indicate that the terminal device has received the QoE measurement configuration, indicating that the terminal device has been triggered to perform QoE measurement. The other IEs field descriptions of the RRC Resume Complete message can be understood by referring to the following Table 1 and the relevant explanations of the 3GPP protocol, which will not be repeated here.
