[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 5, 2023, with application number 202311661758.5 ​​and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communications, and in particular to a communication method and device. Background Art

[0004] The International Telecommunication Union (ITU) defines quality of experience (QoE) as the user's subjective perception of the quality and performance of devices, networks, systems, applications, or services. The Third Generation Partnership Project (3GPP) has standardized QoE-related protocols, including QoE measurement for different services, QoE activation and deactivation processes, and RAN-side QoE measurement interaction protocols.

[0005] Traditionally, for different services (such as voice, video, and images), uniform specifications are typically set for technical indicators (such as latency and packet loss rate). Terminal devices (or network devices) measure the QoE of the service based on these uniform specifications, thereby obtaining QoE measurement information. The QoE server then determines the QoE based on this QoE measurement information. This approach cannot distinguish between different users and determines QoE solely based on objective information related to the service. Consequently, the QoE determined in this way only reflects the objective parameters of the service and cannot reflect the user's actual subjective satisfaction with the service.

[0068] The method provided in the embodiment of the present application can be executed by a network device, or by a component of the network device (such as a processor, a chip, or a chip system, etc.).

[0069] The technical solutions provided in the embodiments of the present application can be applied to various communication systems, such as: fourth generation (4G) systems, fifth generation (5G) systems or new radio (NR) systems or future 3GPP systems.

[0070] For example, the communication system in the embodiment of the present application may be a communication system based on a next-generation (NG) radio access network (RAN) as shown in FIG1 . The network elements / modules involved in the communication system mainly include three parts: an NG RAN, a terminal device (represented by a UE in the figure), and a core network.

[0085] In order to improve the accuracy of QoE and enhance user satisfaction, an embodiment of the present application provides a communication method.

The communication method provided in the embodiment of the present application will be described below in conjunction with the accompanying drawings.

[0086] FIG4 is a communication method provided in an embodiment of the present application, which may include the following steps:

[0087] S401: A network device receives satisfaction information of a first service, wherein the satisfaction information is used to indicate a first user's subjective satisfaction with the first service, and the satisfaction information is determined based on an electroencephalogram (EEG) signal of the first user acquired by a terminal device.

[0088] Exemplarily, the satisfaction information of the first service may be carried in an attention (AT) command; or, the satisfaction information of the first service may be carried in a radio resource control (RRC) layer message.

[0089] Optionally, the network device is a QoE center device, a base station, or a core network device.

[0090] Optionally, the first service may be an audio service, a video service, an image service, etc., and the first service may also be a service provided by any application installed in the terminal device.

[0091] Optionally, the network device may receive the satisfaction information of the first service in the following two ways:

[0092] Method 1:

[0093] Step 1-1: The terminal device obtains the EEG signal of the first user. For example, in the embodiment of the present application, the terminal device may be a head-mounted cellular terminal integrated with a BCI function. The terminal device may obtain the EEG signal of the first user through the BCI.

[0094] Step 1-2: The terminal device determines satisfaction information of the first service based on the EEG signal.

[0095] Steps 1-3: The terminal device sends satisfaction information to a network device (e.g., a QoE center device, a base station, a core network device, etc.); in return, the network device receives the satisfaction information from the terminal device. For example, the terminal device may send an RRC message to the base station, and the RRC message may carry the satisfaction information.

[0096] Method 2:

[0097] Step 2-1: The terminal device obtains the EEG signal of the first user.

[0098] Step 2-2: The terminal device sends an EEG signal to the core network device; in response, the core network device receives the EEG signal from the first user of the terminal device. For example, the terminal device can send the EEG signal to the base station, and the base station forwards the EEG signal to the core network device.

[0099] Step 2-3: The core network device determines satisfaction information of the first service based on the EEG signal.

[0100] Step 2-4: The core network device sends satisfaction information to network devices (e.g., QoE center devices, base stations, other core network devices, etc.); in return, the network device receives the satisfaction information from the core network device. For example, the core network device may send the satisfaction information to the base station, which then forwards the satisfaction information to the network device.

[0101] S402: The network device obtains QoE measurement information of the first service.

[0102] Optionally, the network device may obtain the QoE measurement information of the first service through detection; or, the network device may send the QoE measurement configuration information of the first service to another device and receive the QoE measurement information of the first service from the device.

[0103] It should be understood that the execution order of step S401 and step S402 can be adjusted and is not limited in this application. For example, step S401 and step S402 can be executed at the same time.

[0104] S403: The network device determines a first QoE of the first user for the first service according to the QoE measurement information and the satisfaction information.

[0105] In actual applications, different manufacturers set private implementations of QoE algorithms, and there is currently no unified calculation method; therefore, this application does not limit the method for network devices to determine the first QoE.

[0106] In one possible design, the QoE measurement information includes at least one sub-measurement information, and the process of determining the first QoE may include the following steps:

[0107] Step 3-1: The network device normalizes at least one sub-measurement information.

[0108] Step 3-2: The network device normalizes the satisfaction information.

[0109] Step 3-3: The network device determines a first QoE according to the normalized at least one sub-measurement information and the normalized satisfaction information.

[0110] Optionally, if there are multiple (greater than or equal to two) sub-measurement information, the network device can take the average of the normalized results corresponding to the multiple sub-measurement information to obtain a first reference QoE (or objective QoE); the network device can use the result of the above-mentioned normalization processing of the satisfaction information as the second reference QoE (or subjective QoE); the network device determines the first QoE based on the first reference QoE and the second reference QoE.

[0111] For example, in a video streaming service, the network device performs normalization processing on N QoE measurement information such as data rate, transmission delay, and frame drop rate, that is, maps them to a value between (0, 1) respectively; the network device takes the average of the N normalization results to obtain QoE (1), and the value of QoE (1) is between (0, 1); the network device can normalize the satisfaction information to obtain QoE (2), and the value of QoE (2) is between (0, 1); the network device calculates the first QoE = (QoE (1) + QoE (2)) / 2.

[0112] In one possible design, when the first QoE is less than a QoE threshold, the network device may adjust the QoS of the first service. QoS adjustment methods vary in different application scenarios. The network device may adjust the QoS of the first service in accordance with conventional methods and is not limited in this application. For example, the network device may increase the number of communication interfaces, reduce link packet transmission latency, and so on.

[0113] The network device may pre-set the QoE threshold, or the network device may determine the QoE threshold based on protocol provisions, or the terminal device may determine the threshold based on the service type of the first service, which is not limited in this application. For example, the network device may set the QoE threshold to 0.5.

[0114] By adopting the method and design shown in the aforementioned steps S401 to S403, the network device can determine the first QoE by combining the first user's subjective satisfaction with the first service and the QoE measurement information, thereby improving the accuracy of QoE and thus improving user satisfaction.

[0115] In one possible design, the network device is a QoE center device. The QoE center device may be a TCE or an MCE. Based on the method shown in FIG4 of the embodiment of the present application, in this design, the process of the method can be referred to as shown in FIG5a:

[0116] Step 5a-1: The QoE center device receives satisfaction information of the first service. Step 5a-1 can refer to the aforementioned step S401 and will not be described in detail here.

[0117] The process of obtaining the QoE measurement information of the first service in the aforementioned step S402 includes but is not limited to the following two implementation methods:

[0118] Method A1:

[0119] Step 5a-2: The QoE center device sends first QoE measurement configuration information to the terminal device; accordingly, the terminal device receives the first QoE measurement configuration information from the QoE center device; the first QoE measurement configuration information is used to instruct the terminal device to determine QoE measurement information.

[0120] Step 5a-3: The terminal device sends QoE measurement information to the QoE center device; correspondingly, the QoE center device receives the QoE measurement information from the terminal device.

[0121] Optionally, when the QoE center device in step 5a-1 receives the satisfaction information of the first service using the aforementioned method 1, the satisfaction information in step 5a-1 and the QoE measurement information in step 5a-3 can be carried in the same information (eg, the same measurement report).

[0122] Method A2:

[0123] Step 5a-4: The QoE center device sends second QoE measurement configuration information to the base station to which the terminal device accesses. Correspondingly, the base station receives the QoE measurement configuration information from the QoE center device. The second QoE measurement configuration information is used to instruct the base station to determine QoE measurement information.

[0124] Step 5a-5: The base station sends QoE measurement information to the QoE center device; accordingly, the QoE center device receives the QoE measurement information from the base station; the QoE measurement information is used by the QoE center device to determine the first QoE of the first user.

[0125] It should be understood that either the aforementioned method A1 or the method A2 can be executed alone without having to be executed repeatedly.

[0126] Steps 5a-6: The QoE center device determines the first QoE of the first user for the first service based on the QoE measurement information and the satisfaction information. Steps 5a-6 can refer to the aforementioned step S403 and are not described again here.

[0127] Based on the above design, the QoE center device may further perform the following two processing methods for the first QoE of the first user for the first service obtained:

[0128] Method B1:

[0129] Step 5a-7: The QoE center device sends a first QoE to the ISP device; in response, the ISP device receives the first QoE of the first user for the first service from the QoE center device, wherein the first QoE is used to adjust the QoS of the first service.

[0130] Optionally, after receiving the first QoE, the ISP device may further perform the following steps:

[0131] Steps 5a-8: When the first QoE is less than the threshold, the ISP device adjusts the QoS of the first service. The ISP device is used to adjust the signal source, and the operation is generally complex. The following uses the first service as a video stream as an example to illustrate the operation of the ISP device.

[0132] Optionally, when the first service includes transmission of at least one video stream, adjusting the QoS of the first service in the aforementioned steps 5a-8 includes: the ISP device performing at least one of the following operations: reducing the resolution of the video stream; reducing the frame rate of the video stream.

[0133] Conversely, when the QoE is greater than or equal to the threshold, the ISP retains the current video resolution and source data rate unchanged.

[0134] Method B2:

[0135] Step 5a-9: The QoE center device sends a first QoE to the OAM device; correspondingly, the OAM device receives the first QoE of the first user for the first service from the QoE center device, wherein the first QoE is used to adjust the QoS of the first service.

[0136] Optionally, after receiving the first QoE, the OAM device may further perform the following steps:

[0137] Step 5a-10: When the first QoE is less than the threshold, the OAM device adjusts the QoS of the first service. The OAM device is used to adjust the configuration of the communication network, and its operation is generally complex. The operation of the OAM device is described below as an example.

[0138] Optionally, adjusting the QoS of the first service in steps 5a-10 includes: the OAM device performing at least one of the following operations: increasing the number of gateway routes; increasing the amount of bandwidth enabled for the base station; or instructing the base station to increase the amount of air interface resources allocated to the terminal device. This can increase the transmission rate from the network device to the terminal device and reduce transmission latency.

[0139] On the contrary, when the QoE is greater than or equal to the threshold, the OAM device keeps the current network configuration unchanged.

[0140] In another possible design, the network device is a base station or a core network device. Figure 5b shows another communication method provided in an embodiment of the present application. For ease of description, the term "network device" will be used to refer to a base station or a core network device in the following text.

[0141] Step 5b-1: The network device receives satisfaction information of the first service. Step 5b-1 can refer to the aforementioned step S401 and will not be described in detail here.

[0142] The process of obtaining the QoE measurement information of the first service in the aforementioned step S402 includes but is not limited to the following two implementation methods:

[0143] Method C1:

[0144] Step 5b-2: The network device sends third QoE measurement configuration information to the terminal device; accordingly, the terminal device receives the third QoE measurement configuration information from the network device; wherein the third QoE measurement configuration information is used to instruct the terminal device to determine QoE measurement information.

[0145] Step 5b-3: The terminal device sends the QoE measurement information to the network device; correspondingly, the network device receives the QoE measurement information from the terminal device.

[0146] Method C2:

[0147] Step 5b-4: The network device obtains QoE measurement information through measurement.

[0148] It should be understood that only one of the above-mentioned methods C1 and C2 can be executed without repeated execution.

[0149] Step 5b-5: The network device determines the first QoE of the first user for the first service based on the QoE measurement information and the satisfaction information. Step 5b-5 can refer to the aforementioned step S403 and will not be described in detail here.

[0150] Figure 6a is an example diagram of a communication method provided in an embodiment of the present application. The communication method is applicable to any of the communication systems in Figures 1 to 3 above; wherein the UE includes a UE assessment system (AS) (hereinafter referred to as UE AS) and a UE application (APP) program (hereinafter referred to as UE APP); the core network device can be the core network device in Figure 1, or it can be a device composed of an AMF network element and / or a LMF network element in Figure 3. The communication method includes the following steps:

[0151] Step 6a-1: The UE AS sends the UE capability information to the NG RAN.

[0152] Step 6a-2: The core network device (hereinafter referred to as CN) sends a QoE measurement activation request to the NG RAN. The QoE measurement activation request may include QoE measurement configuration information. The QoE measurement configuration information may refer to the QoE measurement configuration information of the first service in step S402.

[0153] Step 6a-3: The NG RAN (eg, any base station) may send the aforementioned QoE measurement configuration information to the UE AS via an RRC message.

[0154] Step 6a-4: The UE AS sends the aforementioned QoE measurement configuration information to the UE APP via an AT command.

[0155] Step 6a-5: The UE APP obtains the user's EEG signal through the BCI, and determines the user's brain satisfaction (brain acceptance) of the service (eg, the first service in the aforementioned steps S401 to S403).

[0156] Optionally, considering that the brain's reaction time is in seconds, the reporting period of the brain satisfaction and the reporting period of the QoE measurement configuration information can be different. For ease of description, the subsequent steps are described exemplarily based on the same reporting period.

[0157] Step 6a-6: The UE APP sends a QoE report to the UE AS through an AT command. The QoE report may include brain satisfaction and QoE measurement configuration information.

[0158] Steps 6a-7: The UE AS sends a QoE report to the NG RAN via an RRC message. The QoE report may include brain satisfaction and QoE measurement configuration information. The execution process of steps 6a-5 to 6a-7 can refer to the method 1 in the aforementioned step S401 and will not be repeated here.

[0159] Steps 6a-8: NG RAN forwards the QoE report to TCE (or MCE, base station).

[0160] Optionally, after the TCE (or MCE, base station) obtains the aforementioned QoE report, the following steps may be further performed:

[0161] Steps 6a-9: The TCE (or MCE, or base station) completes the QoE calculation (refer to the first QoE calculation process described above). The TCE (or MCE, or base station) sends the QoE to the ISP (or OAM). The QoE calculation process can be referred to in step S403 above and will not be repeated here.

[0162] In this way, brain satisfaction, that is, the user's subjective satisfaction with the service, is added to the QoE calculation process, which can achieve a more accurate QoE evaluation.

[0163] Figure 6b is an example diagram of a communication method provided in an embodiment of the present application. The communication method is applicable to any of the communication systems in Figures 1 to 3 above; wherein the UE includes a UE AS and a UE APP. The communication method includes the following steps:

[0164] Step 6b-1: The NG RAN sends a QoE configuration container to the UE AS via an RRC message. The QoE configuration container includes a measurement indication and QoE measurement configuration information. The measurement indication is used to instruct the acquisition of RAN-visible brain satisfaction information, and the first indication can also be used to instruct the acquisition of QoE measurement information. For example, the QoE measurement configuration information can be sent to the UE AS together with other QoE measurement configuration information from the OAM. The NG RAN can send the RRC message to the CN, which forwards the RRC information to the UE AS.

[0165] It should be understood that based on the aforementioned measurement indication, the obtained QoE measurement information and brain satisfaction are both information visible to the RAN. The aforementioned measurement indication can be a single value, or the aforementioned measurement indication can be a combination of values ​​reflecting QoE metrics useful to the RAN (e.g., buffer level).

[0166] Step 6b-2: The UE AS sends the aforementioned measurement instruction and / or QoE measurement configuration information to the UE APP via an AT command.

[0167] Step 6b-3: The UE APP obtains the user's EEG signal through the BCI and determines the user's brain satisfaction (brain acceptance) of the service (eg, the first service).

[0168] Step 6b-4: The UE APP sends a QoE report to the UE AS through an AT command. The QoE report may include brain satisfaction and QoE measurement information.

[0169] Step 6b-5: The UE AS sends a QoE report to the NG RAN via an RRC message. This QoE report may include brain satisfaction and QoE measurement information. It should be understood that the NG RAN can directly obtain the brain satisfaction and QoE measurement information in the QoE report. The execution process of steps 6b-3 to 6b-5 can refer to the method 1 described in step S401 above and will not be repeated here.

[0170] Optionally, the aforementioned QoE report is included in an independent event (IE) message of a measurement report application layer (meas report App layer), but the QoE report can be a separate IE message.

[0171] In this way, the RAN side can see the brain satisfaction, so that the RAN side can accurately adjust the QoS based on the brain satisfaction, thereby improving user satisfaction.

[0172] Figure 6c is an example diagram of a communication method provided in an embodiment of the present application. Compared to Figures 6a and 6b above, a brain signal processing unit (e.g., BrainF) is added to the core network device to perform feature extraction, recognition and classification of brain signals, and electroencephalogram (EEG) processing of brain signals. The method includes the following steps:

[0173] A consensus is reached between multiple devices (such as TCE, MCE, BrainF, NG RAN and UE) on QoE measurement configuration information and UE capability information. The specific implementation method can refer to traditional technologies in the field and is not limited in this application.

[0174] Step 6c-1: The UE sends QoE measurement information to the NG RAN. The execution process of step 6c-1 can refer to the above-mentioned method C1 and will not be repeated here.

[0175] Step 6c-2: The UE sends the QoE measurement information to the TCE (or MCE). The execution process of step 6c-2 can refer to the above-mentioned method A1 and will not be repeated here.

[0176] It should be understood that only one of step 6c-1 and step 6c-2 needs to be executed, and there is no need to repeat them.

[0177] Step 6c-3: The UE obtains the user's brain electrical signals (eg, EEG) through the BCI.

[0178] Step 6c-4: UE sends the EEG signal to Brain F. Furthermore, Brain F may determine brain satisfaction based on the EEG signal.

[0179] Step 6c-5: BrainF sends the brain satisfaction score to NG RAN. The execution process of step 6c-5 can refer to the second method in the above step S401 and will not be repeated here.

[0180] Step 6c-6: BrainF sends the brain satisfaction to TCE (or MCE). The execution process of step 6c-6 can refer to the second method in the above step S401, and will not be repeated here.

[0181] It should be understood that either step 6c-5 or step 6c-6 can be performed, and there is no need to perform them repeatedly. Generally speaking, when step 6c-1 is being performed, step 6c-5 is performed; when step 6c-2 is being performed, step 6c-6 is performed.

[0182] In this way, the UE sends the EEG signal to the brain signal processing unit (i.e. BrainF) added in the core network. BrainF can complete the feature extraction, recognition and classification of EEG signals, etc., thereby outputting the user's brain satisfaction with the service.
