Description

Quality of Experience (QoE) configuration method, device, and storage medium

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on August 4, 2023, with application number CN202310981551.X and application name “Quality of Experience (QoE) configuration method, device and storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a method, device, and storage medium for configuring quality of experience (QoE). Background Art

[0003] QoE measurement involves measuring the performance parameters of a carrier network using user equipment (UE) and sending the results to the carrier's equipment. After receiving the results, the carrier's equipment can optimize the network based on the measurements provided by the UE. This allows the carrier network to provide a better user experience for the UE.

[0004] In the related art, when performing QoE measurement, the source access network device sends QoE measurement configuration information to the terminal device, and the corresponding terminal device receives the QoE measurement configuration information. The terminal device saves the QoE measurement configuration information and performs QoE measurement based on the QoE measurement configuration information. However, when the terminal device is in an idle state, the source access network device deletes the QoE measurement configuration information corresponding to the terminal device. After the terminal device reconnects to the target access network device, the target access network device does not save the QoE measurement configuration information corresponding to the terminal device. In this way, when the idle terminal device switches cells, the target access network device to which the switched cell belongs will not be able to configure QoE measurement configuration information for the terminal device, resulting in the terminal device being unable to perform QoE measurement after switching cells. Therefore, how to solve the problem that idle terminal devices are unable to perform QoE measurement after cell switching is a technical problem that still needs to be solved.

[0070] Before explaining the embodiments of the present invention in detail, some related technologies involved in the embodiments of the present invention are first introduced.

[0071] The following explains the terms involved in the embodiments of the present application to facilitate readers' understanding.

[0072] 1. QoE Measurement

[0073] QoE measurement refers to measuring users' comprehensive subjective experience of service quality and performance (including effectiveness and availability). This refers to measuring users' experience with service applications. This allows operators to comprehensively evaluate service quality and performance based on QoE measurement results. Operators can identify service issues based on these comprehensive user evaluations and make adaptive adjustments to their communication networks accordingly.

[0074] It should be noted that QoE measurement includes: 1.1, signaling-based QoE measurement, and 1.2, management-based QoE measurement. The following details each of these:

[0075] 1.1 Signaling-based QoE Measurement

[0076] Signaling-based QoE measurement refers to QoE measurement performed on a specific terminal device, and signaling-based QoE measurement can be performed in real time.

[0077] As shown in FIG1 , the signaling-based QoE measurement process includes the following S101 - S108 .

[0078] S101. The access stratum (AS) layer of a terminal device sends capability information to a next generation radio access network (NG-RAN) in a fifth generation mobile communication technology (5G) network. In response, the NG-RAN receives the capability information sent from the AS layer of the terminal device.

[0079] The capability information is used to indicate that the terminal device has the capability of QoE measurement.

[0080] In a possible implementation, the capability information may be capability information sent by the terminal device to the NG-RAN.

[0081] In an optional implementation, the above S101 can be executed after S103, that is, after the NG-RAN receives the activation QoE measurement information from the core network device, the terminal device sends the capability information to the NG-RAN through signaling.

[0082] S102: Operations and maintenance (OAM) equipment sends configuration QoE measurement information to the core network equipment. Correspondingly, the core network equipment receives the configuration QoE measurement information from the OAM equipment.

[0083] The configured QoE measurement information is used to trigger the core network device to configure QoE measurement, and carries QoE measurement configuration parameters.

[0084] 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 core network device.

[0085] It should be noted that the above-mentioned configured QoE measurement information may include a configuration range of QoE measurement and required QoE measurement configuration parameters.

[0086] It should be noted that if the NG-RAN determines based on the capability information that the terminal device does not have the QoE measurement capability, the OAM device will also send the QoE measurement configuration information to the core network device. In other words, if the NG-RAN determines based on the capability information that the terminal device does not have the QoE measurement capability, S102-S103 will continue to execute, but S104-S108 will not continue to execute.

[0087] It should be noted that OAM equipment refers to functional network elements that operate, manage, and maintain communications networks based on the actual needs of operators' network operations. Operation primarily refers to the analysis, forecasting, planning, and configuration of communications networks and services within them. Management primarily refers to the management and monitoring of data within the communications network. Maintenance primarily involves testing and fault management of the communications network and its services.

[0088] S103: The core network device sends activation QoE measurement information to the NG-RAN. Correspondingly, the NG-RAN receives the activation QoE measurement information from the core network device.

[0089] The activated QoE measurement information includes QoE measurement configuration parameters.

[0090] In a possible implementation, the activation QoE measurement information may be Activate QoE Measurement information sent by the core network device to the NG-RAN.

[0091] 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.

[0092] The above-mentioned core network equipment may include at least one of the following network element function entities: access and mobility management function (AMF), session management function (SMF), UPF, authentication service function (AUSF), network slice selection function (NSSF), network exposure function (NEF), policy control function (PCF), and unified data management function (UDM).

[0093] Among them, the specific functions of the above-mentioned network element functional entities are as follows: AMF is responsible for user access and mobility management; SMF is responsible for user session management; AUSF is responsible for authenticating users' 3GPP and non-3GPP access; UPF is responsible for user plane processing; NSSF is responsible for selecting network slices used by user services; NEF is responsible for opening the capabilities of the 5G network to external systems; PCF is responsible for user policy control, including session policy, mobility policy, etc.; UDM is responsible for user contract data management.

[0094] S104: NG-RAN sends radio resource control information to the AS layer of the terminal device. Correspondingly, the AS layer of the terminal device receives the radio resource control information from NG-RAN.

[0095] The radio resource control information includes QoE measurement configuration parameters.

[0096] It should be noted that radio resource control information is sent from the NG-RAN to the terminal device in the form of radio resource control signaling. Radio resource control information can also be sent from the NG-RAN to the terminal device via the physical downlink control channel (PDCCH). Radio resource control information can also be sent from the NG-RAN to the terminal device via radio resource control signaling pre-configuration information. Radio resource control information can also be sent from the NG-RAN to the terminal device via PDCCH activation information.

[0097] In a possible implementation, the radio resource control information may be a radio resource control (RRC) message sent by the NG-RAN to the access layer of the terminal device.

[0098] Optionally, NG-RAN can generate radio resource control information and send it 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.

[0099] S105: The AS layer of the terminal device sends a mobile terminal command to the application (APP) layer of the terminal device. Correspondingly, the APP layer of the terminal device receives the mobile terminal command from the AS layer of the terminal device.

[0100] The mobile terminal command includes QoE measurement configuration parameters.

[0101] In a possible implementation manner, the mobile terminal command may be an access termination command.

[0102] S106: The APP layer of the terminal device sends a mobile terminal command to the AS layer of the terminal device. Correspondingly, the AS layer of the terminal device receives the mobile terminal command from the APP layer of the terminal device.

[0103] Among them, the mobile terminal command is used to instruct the APP layer of the terminal device to report the QoE measurement report to the AS layer of the terminal.

[0104] In a possible implementation manner, the mobile terminal command may be an access termination command.

[0105] It should be noted that after the APP layer of the terminal device receives the mobile terminal command including the QoE measurement configuration parameters sent from the AS layer of the terminal device, the terminal device performs QoE measurement according to the QoE measurement configuration parameters and generates a QoE measurement report.

[0106] S107: The AS layer of the terminal device sends radio resource control information to the NG-RAN. Correspondingly, the NG-RAN receives the radio resource control information from the AS layer of the terminal device.

[0107] The radio resource control information includes a QoE measurement report.

[0108] In one possible implementation, the radio resource control information may be an RRC Message sent by the AS layer of the terminal device to the NG-RAN.

[0109] S108. The NG-RAN sends a QoE measurement report to the terminal control element (TCE) / media access control element (MCE). Correspondingly, the TCE / MCE receives the QoE measurement report from the NG-RAN.

[0110] In one possible implementation, the QoE measurement report may be a QoE measurement report QoE Report sent by NG-RAN to TCE / MCE.

[0111] The above describes the signaling-based QoE measurement process in detail. The following describes the management-based QoE measurement process in detail.

[0112] 1.2 Management-based QoE Measurement

[0113] 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 (that is, the next stage after the pre-processing stage is completed).

[0114] As shown in FIG2 , the management-based QoE measurement process includes the following S201 - S207 .

[0115] 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.

[0116] It should be noted that S201 is similar to the above-mentioned S101 and can be understood with reference to the above-mentioned S101, which will not be repeated here.

[0117] 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.

[0118] The activated QoE measurement information carries QoE measurement configuration parameters.

[0119] In a possible implementation, the activation QoE measurement information may be activation QoE measurement (Activate QoE Measurement) information sent by the OAM device to the NG-RAN.

[0120] It should be noted that S202 differs from S102 described above in that: In S202, the OAM device can directly send the activation QoE measurement information to the NG-RAN; whereas in S102, the OAM device must first send the configuration QoE measurement information to the core network device. The core network device then generates the activation QoE measurement information based on the configuration QoE measurement information and sends it to the NG-RAN. Because management-based QoE measurement does not require core network devices to relay information, the activation QoE measurement information can be sent directly from the OAM device to the NG-RAN.

[0121] S203: NG-RAN sends radio resource control information to the AS layer of the terminal device. Correspondingly, the AS layer of the terminal device receives the radio resource control information from NG-RAN.

[0122] It should be noted that S203 is similar to the above-mentioned S104 and can be understood with reference to the above-mentioned S104, which will not be repeated here.

[0123] S204: The AS layer of the terminal device sends a mobile terminal command to the APP layer of the terminal device. Correspondingly, the APP layer of the terminal device receives the mobile terminal command from the AS layer of the terminal device.

[0124] It should be noted that S204 is similar to the above-mentioned S105 and can be understood with reference to the above-mentioned S105, which will not be repeated here.

[0125] S205: The APP layer of the terminal device sends a mobile terminal command to the AS layer of the terminal device. Correspondingly, the AS layer of the terminal device receives the mobile terminal command from the APP layer of the terminal device.

[0126] It should be noted that S205 is similar to the above-mentioned S106 and can be understood with reference to the above-mentioned S106, which will not be repeated here.

[0127] S206: The AS layer of the terminal device sends radio resource control information to the NG-RAN. Correspondingly, the NG-RAN receives the radio resource control information from the AS layer of the terminal device.

[0128] It should be noted that S206 is similar to the above-mentioned S107 and can be understood with reference to the above-mentioned S107, which will not be repeated here.

[0129] S207: NG-RAN sends a QoE measurement report to the TCE / MCE. Correspondingly, the TCE / MCE receives the QoE measurement report from the NG-RAN.

[0130] It should be noted that S207 is similar to the above-mentioned S108 and can be understood with reference to the above-mentioned S108, which will not be repeated here.

[0131] 2. Configuration of Broadcast Services

[0132] As shown in FIG3 , the specific process of the broadcast service configuration flow may include the following S301 - S318 .

[0133] S301: The target network element allocates a temporary mobile group identity (TMGI) and creates a multicast and broadcast service (MBS) session.

[0134] The target network elements include: application function (AF), network element function (NEF) / multicast broadcast service function (MBSF), packet control function (PCF), multicast broadcast user plane function (MB-UPF), and multicast broadcast session management function (MB-SMF).

[0135] It should be noted that the specific implementation process of the above-mentioned TMGI allocation MBS session creation can refer to the existing technology, and this application will not elaborate on it.

[0136] S302: MB-SMF sends a broadcast context creation request to AMF. Correspondingly, AMF receives the broadcast context creation request from MB-SMF.

[0137] The broadcast context creation request may include: TMGI, synchronization status message (SSM), 5G authorized service quality profile (5G authorized Qos profile), and MBS service area (MBS service area).

[0138] It should be noted that the above is only an example of a broadcast context creation request. The broadcast context creation request may also include other information, and this application does not impose any limitation on this.

[0139] In a possible implementation, the broadcast context creation request may be a Namf_MBSB roadcast Context Create Request sent by MB-SMF to AMF.

[0140] S303. The AMF sends an N2 information request to the NG-RAN-central unit--user plane (NG-RAN-CU-UP) unit in the 5G network. Accordingly, the NG-RAN-CU-CP receives the N2 information request from the AMF.

[0141] The N2 information request may include: TMGI, SSM, 5G authorized service quality profile (5G authorized Qos profile), and MBS service area.

[0142] In one possible implementation, the N2 information request may be an N2message Request sent by the AMF to the NG-RAN-CU-UP unit.

[0251] QoE measurement involves a terminal device measuring the performance parameters of a carrier network and sending the results to the carrier's equipment. After receiving the results, the carrier's equipment can optimize the network based on the measurements provided by the terminal device. This allows the carrier network to provide a better user experience for the terminal device.

[0252] In related technologies, when performing QoE measurements, the source access network device sends QoE measurement configuration information to the terminal device, and the corresponding terminal device receives the QoE measurement configuration information. The terminal device saves the QoE measurement configuration information and performs QoE measurements based on the QoE measurement configuration information. When the terminal device is in an inactive state, the connecting NG-RAN sends a Retrieve UE Context Request message to the last serving NG-RAN. Simultaneously, the last serving NG-RAN sends a Retrieve UE Context Response message to the connecting NG-RAN. In this way, the connecting NG-RAN obtains the QoE parameter set of the terminal device in the last serving NG-RAN based on the Retrieve UE Context Response, and the connecting NG-RAN then performs QoE measurement configuration for the terminal device based on the QoE parameter set of the terminal device.

[0253] However, when a terminal device is in an idle state, the source access network device deletes the QoE measurement configuration information corresponding to the terminal device. After the terminal device reconnects to the target access network device, the target access network device does not save the QoE measurement configuration information corresponding to the terminal device. As a result, when an idle terminal device switches cells, the target access network device to which the switched cell belongs will be unable to configure the QoE measurement configuration information for the terminal device, resulting in the terminal device being unable to perform QoE measurements after switching cells. Therefore, how to solve the problem of idle terminal devices being unable to perform QoE measurements after a cell switch is a technical problem that remains to be solved.

[0254] In order to solve the technical problems existing in the related art, in the present application, after the terminal device in the idle state re-establishes the connection with the target access network device, the terminal device sends a QoE parameter set to the target access network device, and accordingly, the target access network device receives the QoE parameter set from the terminal device. In this way, the target access network device can obtain the QoE parameters of the terminal device. Based on this, the target access network device can generate the QoE parameters of the terminal device based on the QoE parameter set, send the QoE parameters to the terminal device, and then enable the terminal device to perform QoE measurement according to the QoE parameters. The problem in the prior art that the idle terminal device cannot perform QoE measurement after cell switching due to the lack of the QoE parameters of the terminal device in the target access network device (that is, the access network device to which the terminal device in the idle state establishes a connection after cell reselection) is solved.

[0255] The following describes in detail the QoE configuration method provided in the embodiment of the present application with reference to FIG8 . As shown in FIG8 , the QoE configuration method includes:

[0256] S801. The terminal device obtains a QoE parameter set.

[0257] The QoE parameter set is a QoE parameter set visible to the access network device.

[0258] Optionally, the QoE parameter set visible to the access network device indicates a set of all or some parameters that can be used for optimization and that are configured by the OAM device for the multiple access network devices. Optionally, each of the all or some parameters is an unencapsulated parameter, so that the multiple access network devices can directly obtain the QoE parameters in the QoE parameter set without decapsulation.

[0259] S802: After the terminal device reselects a cell in an idle state, the terminal device sends first information to the target access network device it is currently connected to. Correspondingly, the target access network device receives the first information from the terminal device.

[0260] The first information includes a QoE parameter set.

[0261] Optionally, the first information further includes a target QoE reference identifier, where the target QoE reference identifier is used to mark the QoE measurement to be measured in the terminal device.

[0262] It should be noted that the terminal device includes at least one QoE reference identifier.

[0263] Optionally, the QoE measurement may be a QoE measurement of an application to be measured in the terminal device. Accordingly, the QoE reference identifier is an identifier of the application to be measured.

[0264] Exemplarily, the identifiers of the target QoE reference identifier include: an identifier of terminal application 1 , an identifier of terminal application 2 , an identifier of terminal application 3 , and an identifier of terminal application 4 .

[0265] In one possible implementation, since the first information includes a target QoE reference identifier, after receiving the first information, the target access network device can determine, from a QoE parameter set, the target QoE measurement corresponding to the target QoE reference identifier and the second QoE measurement configuration parameters for the target QoE measurement based on the target QoE reference identifier in the first information. Thereafter, the target access network device generates second QoE measurement configuration information based on the second QoE measurement configuration parameters and sends the second QoE measurement configuration information to the terminal device based on the identifier of the terminal device. Based on this, the target access network device can configure appropriate second QoE measurement configuration parameters for the terminal device based on the needs of the terminal device.

[0266] In another possible implementation, the OAM device configures a QoE reference identifier corresponding to each QoE measurement in multiple QoE measurements, and sends the QoE reference identifier corresponding to each QoE measurement configuration in the multiple QoE measurements to the source access network device. The source access network device constructs a QoE reference list based on the QoE reference identifier, the QoE measurement corresponding to the QoE reference identifier, and the QoE measurement configuration parameter corresponding to the QoE reference identifier, and sends the QoE reference list to the terminal device. After the target access network device obtains the QoE reference list from the terminal device, the target access network device can determine a second QoE measurement configuration parameter from at least one QoE measurement configuration parameter in the QoE parameter set based on the target QoE reference identifier and the QoE reference list in the first information.

[0267] Optionally, after the terminal device reselects a cell in an idle state, when the reselected cell and the cell before reselection may belong to the same access network device, the target access network device is the source access network device, and the source access network device is the access network device with which the terminal device established a connection before reselecting the cell.

[0268] Optionally, the carrying method of the first information sent by the terminal device to the target access network device includes the following method 1 and method 2, namely: method 1, the first information is carried in the connection establishment completion message; method 2, the first information is carried in the first QoE measurement report.

[0269] The following is a detailed description of Method 1 and Method 2:

[0270] Method 1: The first information is carried in a connection establishment completion message.

[0271] Optionally, the first information is carried in a connection establishment completion message sent by the terminal device to the target access network device.

[0272] Optionally, the connection establishment completion message is an RRC establishment completion message, that is, RRCSetupComplete-v1610-IEs.

[0273] As in Example 1, the specific message content of the connection establishment completion message carrying the first information may include:

[0274] In this case, the first information may specifically be:

[0275] Optionally, the terminal device may send a connection establishment completion message to the target access network device in the form of radio resource control signaling; or, the terminal device may also send a connection establishment completion message to the target access network device through a physical uplink control channel (PUCCH); or, the terminal device may send a connection establishment completion message to the target access network device through radio resource control signaling pre-configuration information; or, the terminal device may also send a connection establishment completion message to the target access network device through PUCCH activation information.

[0276] It is understandable that since the first information is carried in the connection establishment completion message sent by the terminal device to the target access network device, when the terminal device switches to the target access network device, the terminal device can promptly send a QoE parameter set to the target access network device after the connection with the target access network device is established. This allows the target access network device to generate a second QoE measurement configuration parameter based on the QoE parameter set and perform QoE measurement configuration for the terminal device. This improves the efficiency of QoE measurement after a cell handover occurs in an idle terminal device.

[0277] In addition, since the first information in this application is carried in the connection establishment completion message sent by the terminal device to the target access network device, rather than the terminal device sending the first information to the target access network device separately, the amount of information sent by the terminal device can be reduced, thus avoiding waste of resources.

[0278] Method 2: The first information is carried in the first QoE measurement report.

[0279] Optionally, the first information is carried in a first QoE measurement report sent by the terminal device to the target access network device.

[0280] Among them, the first QoE measurement report is a report generated by the terminal device based on the first QoE measurement configuration parameter information sent by the source access network device for QoE measurement. The source access network device is the access network device that establishes a connection before the terminal device performs cell reselection, and the first QoE measurement configuration parameter information is generated based on the QoE parameter set.

[0281] Optionally, the first QoE measurement configuration parameter information is information generated by the source access network device according to the QoE parameter set.

[0282] In a possible implementation, the terminal device generates first wireless resource control information according to the first QoE measurement report; the AS layer of the terminal device sends the first wireless resource control information to the target access network device.

[0283] Optionally, the first wireless resource control information may be an RRC Message sent by the AS layer of the terminal device to the target access network device.

[0284] As in Example 2, the specific message content of the first QoE measurement report carrying the first information may include:

[0285] In this case, the first information may specifically be:

[0286] QoE Reference

[0287] Available RAN Visible QoE Metrics.

[0288] It is understandable that when the terminal device switches from the source access network device to the target access network device, the terminal device still has some first QoE measurement reports that have not been reported to the source access network device. At this time, the terminal device has already switched to the target access network device, and the terminal device can report the first QoE measurement report to the target access network device.

[0289] Since the first information in this application is carried in the first QoE measurement report sent by the terminal device to the target access network device, based on this, when the terminal device reports the first QoE measurement report to the target access network device, a QoE parameter set can be sent to the target access network device. In this way, the terminal device can send a QoE parameter set to the target access network device in a timely manner after the connection with the target access network device is established. So that the target access network device can generate a second QoE measurement configuration parameter based on the QoE parameter set and perform QoE measurement configuration for the terminal device. The efficiency of QoE measurement after the cell switching of the idle terminal device is improved.

[0290] In addition, since the first information in this application is carried in the first QoE measurement report sent by the terminal device to the target access network device, rather than the terminal device sending the first information to the target access network device separately, the amount of information sent by the terminal device can be reduced, thus avoiding waste of resources.

[0291] The above technical solution brings at least the following beneficial effects: In the present application, after the terminal device in the idle state re-establishes a connection with the target access network device, the terminal device sends a QoE parameter set to the target access network device, and correspondingly, the target access network device receives the QoE parameter set from the terminal device. In this way, the target access network device can obtain the QoE parameters of the terminal device. Based on this, the target access network device can generate the QoE parameters of the terminal device based on the QoE parameter set, send the QoE parameters to the terminal device, and then enable the terminal device to perform QoE measurement according to the QoE parameters. This solves the problem in the prior art that the idle terminal device cannot perform QoE measurement after cell switching due to the lack of the QoE parameters of the terminal device in the target access network device (that is, the access network device to which the terminal device in the idle state establishes a connection after cell reselection).

[0292] In one possible implementation, as shown in FIG9 in conjunction with FIG8 , in the above S801 , obtaining the QoE parameter set can be performed by the terminal device from the source access network device. The process of the terminal device obtaining the QoE parameter set from the source access network device can be specifically implemented through the following S901 - S902 .

[0293] S901. A source access network device obtains a QoE parameter set.

[0294] In a possible implementation, the source access network device receives activation QoE measurement information sent by the core network device, wherein the activation QoE measurement information includes a QoE parameter set.

[0295] It should be noted that the OAM device can determine the QoE measurement to be configured and a set of all or part of the parameters that can be used for access network device optimization (i.e., a QoE parameter set), determine activation configuration information based on the identifier of the QoE measurement to be configured and the QoE parameter set, and send the activation configuration information to the source access network device. Correspondingly, the source access network device receives the activation configuration information from the OAM device and generates second information based on the activation configuration information.

[0296] S902: The source access network device sends second information to the terminal device. Correspondingly, the terminal device receives the second information from the source access network device.

[0297] The source access network device is the access network device that establishes a connection before the terminal device reselects a cell; and the second information includes a QoE parameter set.

[0298] Optionally, the second information further includes a target QoE reference identifier, where the target QoE reference identifier is used to mark the QoE to be measured in the terminal device.

[0299] It should be noted that the second information also includes a target QoE reference identifier. The terminal device can obtain the target QoE reference identifier from the second information and send the target QoE reference identifier to the target access network device. Thereafter, the target access network device generates second QoE measurement configuration information based on the second QoE measurement configuration parameters and sends the second QoE measurement configuration information to the terminal device based on the identifier of the terminal device. Based on this, the target access network device can configure appropriate second QoE measurement configuration parameters for the terminal device according to the needs of the terminal device.

[0300] Optionally, the carrying method of the second information sent by the source access network device to the terminal device includes the following method three and method four, namely: method three, the second information is carried in the first QoE measurement configuration parameter information; method four, the second information is carried in the connection release information.

[0301] The following is a detailed description of Method 3 and Method 4:

[0302] Method three: the second information is carried in the first QoE measurement configuration parameter information.

[0303] Optionally, the second information is carried in the first QoE measurement configuration parameter information sent by the source access network device to the terminal device.

[0304] In a possible implementation, the source access network device generates second radio resource control information according to the first QoE measurement configuration parameter, and sends the second radio resource control information to the AS layer of the terminal device.

[0305] Optionally, the source access network device may send the second wireless resource control information to the terminal device in the form of wireless resource control signaling; or, the source access network device may also send the second wireless resource control information to the terminal device via PDCCH; or, the source access network device may send the second wireless resource control information to the terminal device via wireless resource control signaling pre-configuration information; or, the source access network device may also send the second wireless resource control information to the terminal device via PDCCH activation information.

[0306] As in Example 3, the specific message content of the first QoE measurement configuration parameter information carrying the second information may include:

[0307] In this case, the second information may specifically be:

[0308] It should be noted that when the terminal device accesses the source access network device, it can receive the information sent by the source access network device. Since the second information is carried in the first QoE measurement configuration parameter information sent by the source access network device to the terminal device, before the terminal device switches to the target access network device, the terminal device receives the second information containing the QoE parameter set and stores the QoE parameter set. When the terminal device switches to the target access network device, the terminal device can send the QoE parameter set to the target access network device. This allows the target access network device to generate the second QoE measurement configuration parameter based on the QoE parameter set, perform QoE measurement configuration for the terminal device, and improve the efficiency of QoE measurement after the idle terminal device switches to a cell.

[0309] In addition, since the second information in this application is carried in the first QoE measurement configuration parameter information sent by the source access network device to the terminal device, rather than the source access network device sending the second information separately to the terminal device, the amount of information sent by the source access network device can be reduced, avoiding waste of resources.

[0310] Method 4: The second information is carried in the connection release information.

[0311] Optionally, the second information is carried in the connection release information sent by the source access network device to the terminal device.

[0312] Optionally, the connection release information is an RRC release message, that is, UE Context Release.

[0313] As in Example 4, the specific message content of the connection release information carrying the second information may include:

[0314] In this case, the second information may specifically be:

[0315] It should be noted that when a cell handover occurs, the terminal device sends a cell handover request to the source access network device. In response, the source access network device sends a connection release message to the terminal device. Upon receiving the connection release message, the terminal device disconnects from the source access network device and establishes a communication connection with the target access network device.

[0316] Because the second information is carried in the connection release information sent by the source access network device to the terminal device, the terminal device can receive the second information containing the QoE parameter set from the source access network device before establishing a communication connection with the target access network device. Based on this, the terminal device can promptly send the QoE parameter set to the target access network device after the connection with the target access network device is established. This allows the target access network device to generate the second QoE measurement configuration parameters based on the QoE parameter set, thereby performing QoE measurement configuration for the terminal device and improving the efficiency of QoE measurement for idle terminal devices after cell switching.

[0317] In addition, since the second information in this application is carried in the connection release information sent by the source access network device to the terminal device, rather than the source access network device sending the second information to the terminal device separately, this application can reduce the amount of information sent by the source access network device and avoid wasting resources.

[0318] It should be noted that the terminal device can also obtain the QoE parameter set from other places. For example, the terminal device can obtain the QoE parameter set from the AMF.

[0319] In a possible implementation, after receiving the second information from the source access network device, the terminal device saves the second information; and obtains the QoE parameter set from the second information.

[0320] Optionally, the terminal device saves the second information before obtaining the QoE parameter set.

[0321] In a possible implementation, the terminal device stores the second information in its own storage module.

[0322] The above technical solution brings at least the following beneficial effects: In this application, the source access network device sends the second information including the QoE parameter set to the terminal device, so that the terminal device can save the QoE parameter set. After the terminal device switches to the target access network device, conditions are created for the terminal device to send the QoE parameter set to the target access network device.

[0323] In addition, in the present application, the source access network device sends the second information containing the QoE parameter set to the terminal device in two ways. Since the second information can be carried in the first QoE measurement configuration parameter information sent by the source access network device to the terminal device, the second information can also be carried in the connection release information sent by the source access network device to the terminal device. Based on this, the time it takes for the terminal device to receive the second information from the source access network device is shortened, avoiding the waste of resources caused by the source access network device sending the second information to the terminal device alone, and improving the efficiency of QoE measurement after the idle terminal device undergoes cell switching.

[0324] In a possible implementation, as shown in FIG10 in conjunction with FIG9 , after the terminal device stores the second information in S902 , the terminal device manages the second information. The process of the terminal device managing the second information can be specifically implemented through the following S1001 .

[0325] S1001. If the difference between the time when the terminal device receives the second information and the current time is greater than the effective duration, the terminal device deletes the second information.

[0326] Optionally, the second information also includes a validity period.

[0327] In one possible implementation, after receiving the second information sent by the source access network device, the terminal device records the time when the terminal device receives the second information. The terminal device obtains the validity period in the second information in real time. When the difference between the time when the terminal device receives the second information and the current time is greater than the validity period, the terminal device deletes the second information.

[0328] Exemplarily, after the terminal device receives the second information sent by the source access network device, it records the time when the terminal device receives the second information as 14:30 on October 22, 2022. The valid duration in the second message is 72 hours. If the current time is 12:30 on October 24, 2022, the difference between the time when the terminal device receives the second information and the current time is 46 hours. Since the difference between the time when the terminal device receives the second information and the current time, 46 hours, is less than the valid duration of 72 hours, the terminal device does not delete the second information; if the current time is 12:30 on October 27, 2022, the difference between the time when the terminal device receives the second information and the current time is 118 hours. Since the difference between the time when the terminal device receives the second information and the current time, 118 hours, is greater than the valid duration of 72 hours, the terminal device deletes the second information.

[0329] In another possible implementation, after receiving the second information sent by the source access network device, the terminal device records the time at which the terminal device received the second information. The terminal device obtains the validity period of the second information and determines a target time based on the validity period of the second information and the time at which the terminal device received the second information. If the current time is greater than the target time, the terminal device deletes the second information.

[0330] Exemplarily, after receiving the second message sent by the source access network device, the terminal device records the time at which the terminal device received the second message as 2:30 PM on October 22, 2022. If the validity period in the second message is 72 hours, the preset time is 2:30 PM on October 25, 2022. If the current time is 12:20 PM on October 24, 2022, the current time is less than the preset time, and the terminal device does not delete the second message. If the current time is 12:20 PM on October 27, 2022, the current time is greater than the preset time, and the terminal device deletes the second message.

[0331] The above technical solution provides at least the following beneficial effects: In this embodiment of the present application, if the difference between the time the terminal device receives the second information and the current time is less than or equal to the valid duration, the terminal device does not delete the second information; if the difference between the time the terminal device receives the second information and the current time is greater than the valid duration, the terminal device deletes the second information. This allows the terminal device to delete second information that has been occupying storage space for a long time, alleviating pressure on the terminal device's storage module and enabling the terminal device to accurately manage stored second information.

[0332] In one possible implementation, as shown in FIG11 in conjunction with FIG8 , after the terminal device sends the first information to the currently connected target access network device in S802 , the terminal device performs QoE measurement according to the second QoE measurement configuration parameter. The process of the terminal device performing QoE measurement according to the second QoE measurement configuration parameter can be specifically implemented through the following S1101-S1102.

[0333] S1101. The target access network device sends second QoE measurement configuration parameter information to the terminal device.

[0334] The second QoE measurement configuration parameter information is obtained according to the QoE parameter set.

[0335] Optionally, the second QoE measurement configuration parameter information includes a second QoE measurement configuration parameter, where the second QoE measurement configuration parameter is a QoE measurement configuration parameter corresponding to the target QoE reference identifier in at least one QoE measurement configuration parameter in the QoE parameter set.

[0336] S1102. The terminal device performs QoE measurement according to the second QoE measurement configuration parameter.

[0337] Optionally, after receiving the second QoE measurement configuration parameter from the target access network device, the terminal device may perform QoE measurement based on the second target QoE measurement configuration parameter and generate a second QoE measurement report. The second QoE measurement report may include: the measurement result of the above-mentioned second QoE measurement parameter and the identifier of the second QoE measurement. The terminal device may send the second QoE measurement report to the target access network device. Accordingly, the target access network device receives the second QoE measurement report from the terminal device. After the target access network device receives the QoE measurement report from the terminal device, the target access network device may optimize its own network based on the above-mentioned second QoE measurement report.

[0338] The above technical solution brings at least the following beneficial effects: In an embodiment of the present application, the target access network device determines the second QoE measurement configuration parameter of the terminal device based on the QoE parameter set, and sends the second QoE measurement configuration parameter to the terminal device, thereby solving the problem in the prior art that the idle terminal device cannot perform QoE measurement after cell switching due to the lack of the QoE parameters of the terminal device in the target access network device (that is, the access network device that establishes a connection after the terminal device in the idle state reselects a cell).

[0339] In a possible implementation, as shown in FIG12 in combination with FIG11 , in the above-mentioned S1102 , the process of the terminal device performing QoE measurement according to the second QoE measurement configuration parameter can be specifically implemented through the following S1201 - S1203 .

[0340] S1201: The target access network device determines a second QoE measurement configuration parameter from at least one QoE measurement configuration parameter in a QoE parameter set according to a target QoE reference identifier.

[0341] The second QoE measurement configuration parameter is carried in the second QoE measurement configuration parameter information.

[0342] Optionally, the first information further includes a target QoE reference identifier, where the target QoE reference identifier is used to mark the QoE to be measured in the terminal device.

[0343] Optionally, the target access network device is the access network device to which the terminal device is currently accessed.

[0344] In one possible implementation, the target access network device parses the first information to obtain a target QoE reference identifier; and determines a second QoE measurement configuration parameter from at least one QoE measurement configuration parameter in a QoE parameter set according to the target QoE reference identifier.

[0345] As an optional implementation, the specific implementation process of S1201 may be: the target access network device obtains all or part of the performance parameters of the target access network device from the network management device, and determines a poorer performance parameter from the performance parameters. The target access network device determines, from the QoE parameter set, a parameter that is the same as the poorer performance parameter as the second QoE measurement parameter.

[0346] Optionally, the target access network device may also refer to the service type of the QoE measurement when determining the second QoE measurement parameter. For example, when the service type of the QoE measurement is a video service, the target access network device may select parameters related to the video service (e.g., the number of freezes) from the QoE parameter set, so that the QoE measurement can better adapt to the service requirements.

[0347] In one example, the second QoE measurement parameter may include at least one of the following: packet loss rate, call drop rate, and access success rate. The above is only an exemplary description of the second QoE measurement parameter. The second QoE measurement parameter may also include other parameters (e.g., latency), and this application does not impose any limitation on this.

[0348] It should be noted that the second QoE measurement configuration parameter is determined by the target access network device based on the QoE parameter set; the first QoE measurement configuration parameter is determined by the source access network device based on the QoE parameter set. The second QoE measurement configuration parameter can be the same as or different from the first QoE measurement configuration parameter, and we do not impose any restrictions on this.

[0349] Optionally, the target access network device generates second QoE measurement configuration parameter information according to the second QoE measurement configuration parameter. The second QoE measurement configuration parameter information includes the second QoE measurement configuration parameter.

[0350] Optionally, the target access network device is the access network device to which the terminal device is currently accessed.

[0351] S1202. The target access network device sends second QoE measurement configuration parameter information to the terminal device.

[0352] Correspondingly, the terminal device receives the second QoE measurement configuration parameter information from the target access network device.

[0353] In a possible implementation, the target access network device sends third radio resource control information to the AS layer of the terminal device, where the third radio resource control information includes the second QoE measurement configuration parameter.

[0354] Optionally, the target access network device may send the third wireless resource control information to the terminal device in the form of wireless resource control signaling; or, the target access network device may also send the third wireless resource control information to the terminal device via PDCCH; or, the target access network device may send the third wireless resource control information to the terminal device via wireless resource control signaling pre-configuration information; or, the target access network device may also send the third wireless resource control information to the terminal device via PDCCH activation information.

[0355] In a possible implementation, the third radio resource control information may be an RRC information Message sent by the target access network device to the access layer of the terminal device.

[0356] S1203: The terminal device performs QoE measurement according to the second QoE measurement configuration parameter.

[0357] The above technical solution brings at least the following beneficial effects: In the embodiment of the present application, when a terminal device in an idle state switches a cell, a first message containing a target QoE measurement identifier is sent to a target access network device. The target access network device determines the second QoE measurement configuration parameter of the terminal device from the QoE parameter set based on the target QoE reference identifier. The accuracy of the target access network device configuring the QoE measurement configuration parameter to the terminal device is improved. Furthermore, the target access network device sends the second QoE measurement configuration parameter to the terminal device, which solves the problem in the prior art that the idle terminal device cannot perform QoE measurement after a cell switch occurs because the target access network device (that is, the access network device that establishes a connection after the terminal device in the idle state reselects a cell) does not have the QoE parameters of the terminal device.

[0358] In one possible implementation, as shown in FIG13 in conjunction with FIG9 , before the source access network device sends the second information to the terminal device in S901 , the source access network device obtains a QoE parameter set. The process of the source access network device determining to obtain the QoE parameter set can be specifically implemented through the following S1301 - S1307 .

[0359] S1301. A source access network device receives activation QoE measurement information sent by a core network device.

[0360] The QoE measurement information includes a QoE parameter set.

[0361] S1302: The source access network device obtains a QoE parameter set.

[0362] The specific implementation of S1301 may refer to the above-mentioned S901 and will not be repeated here.

[0363] S1303: The source access network device sends second information to the terminal device. Correspondingly, the terminal device receives the second information from the source access network device.

[0364] The specific implementation of S1302 may refer to the above S902 and will not be repeated here.

[0365] S1304. After the terminal device reselects a cell in an idle state, the terminal device sends first information to the target access network device currently accessed.

[0366] The specific implementation of S1304 may refer to the above S802 and will not be repeated here.

[0367] S1305: The target access network device determines second QoE measurement configuration parameter information from at least one QoE measurement configuration parameter in the QoE parameter set according to the target QoE reference identifier.

[0368] The specific implementation of S1305 may refer to the above S1201 and will not be repeated here.

[0369] S1306. The target access network device sends second QoE measurement configuration parameter information to the terminal device.

[0370] The specific implementation of S1306 may refer to the above S1202 and will not be repeated here.

[0371] S1307. The terminal device performs QoE measurement according to the second QoE measurement configuration parameter.

[0372] The specific implementation of S1307 may refer to the above S1203 and will not be repeated here.

[0373] The above technical solution brings at least the following beneficial effects: In the present application, after the terminal device in the idle state re-establishes a connection with the target access network device, the terminal device sends a QoE parameter set to the target access network device, and correspondingly, the target access network device receives the QoE parameter set from the terminal device. In this way, the target access network device can obtain the QoE parameters of the terminal device. Based on this, the target access network device can generate the QoE parameters of the terminal device based on the QoE parameter set, send the QoE parameters to the terminal device, and then enable the terminal device to perform QoE measurement according to the QoE parameters. This solves the problem in the prior art that the idle terminal device cannot perform QoE measurement after cell switching due to the lack of the QoE parameters of the terminal device in the target access network device (that is, the access network device to which the terminal device in the idle state establishes a connection after cell reselection).

[0374] It can be seen that the above mainly introduces the technical solutions provided by the embodiments of the present application from the perspective of methods. In order to realize the above functions, it includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily appreciate that, in combination with the modules and algorithm steps of each example described in the embodiments disclosed herein, the embodiments of the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in a hardware or computer software driven hardware manner depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present invention.

[0375] In the embodiments of the present application, the QoE configuration device can be divided into functional modules according to the above method examples. For example, each functional module can be divided according to each function, or two or more functions can be integrated into a single processing module. The above integrated modules can be implemented in the form of hardware or software functional modules. Optionally, the module division in the embodiments of the present application is illustrative and is only a logical functional division. In actual implementation, other division methods may be used.

[0376] As shown in FIG14 , it is a schematic diagram of the structure of a QoE configuration device 140 provided in an embodiment of the present application. The QoE configuration device 140 includes: a processing unit 1401 and a communication unit 1402 .

[0377] Processing unit 1401 is used to obtain a QoE parameter set; processing unit 1401 is also used to instruct communication unit 1402 to send first information to the currently accessed target access network device after the terminal device reselects a cell in an idle state, and the first information includes a QoE parameter set.

[0378] Optionally, the first information is carried in a connection establishment completion message.

[0379] Optionally, the first information is carried in a first QoE measurement report; the first QoE measurement report is a report generated by the terminal device for QoE measurement based on the first QoE measurement configuration parameter information sent by the source access network device. The source access network device is an access network device that establishes a connection before the terminal device performs cell reselection, and the first QoE measurement configuration parameter information is generated based on the QoE parameter set.

[0380] Optionally, the communication unit 1402 is further configured to receive second information from a source access network device; the source access network device is an access network device that establishes a connection before the terminal device performs cell reselection; the second information includes a QoE parameter set.
