[0050] To facilitate a better understanding of the embodiments of this application, the related technologies are described.

[0051] (1) Vertical Federated Learning (VFL).

[0052] The essence of VFL is feature federation, which is suitable for scenarios with high user overlap and low feature overlap, such as different services (e.g., MM and SM services, i.e., different data features) serving the same user (e.g., UE, i.e., the same sample) in the CN and RAN domains of a communication network. As shown in Figure 2, by combining the different data features of the common samples of the participating parties, vertical federation increases the feature dimension of the training samples and obtains a better model.

[0053] (2) Artificial Intelligence (AI) / Machine Learning (ML).

[0054] AI has been widely applied in various fields. Integrating artificial intelligence into wireless communication networks to significantly improve technical indicators such as throughput, latency, and user capacity is an important task for future wireless communication networks. AI modules can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. This application uses neural networks as an example for illustration, but it does not limit the specific type of AI module.

[0055] Figure 3 is an example of a neural network structure provided according to an embodiment of this application.

[0056] As shown in Figure 3, X1~X n Let Y be the input value and Y be the output. Each circle represents a neuron, the place where calculations are performed. The results of these calculations are then passed to the next layer. These numerous neurons forming the input layer, hidden layer, and output layer constitute a neural network. The number of hidden layers and the number of neurons in each layer define the "network structure" of the neural network. It should be understood that this application uses a neural network as an example for illustration, but it does not limit the specific type of AI module.

[0057] Figure 4 is an example of the structure of a neuron provided according to an embodiment of this application.

[0058] As shown in Figure 4, the neural network consists of neurons. The output of a neuron is z, where z = a1w1 + ... + a k w k +…+a K w K +b. Where a1~a K For input, w1~w K σ is the weight (multiplicative coefficient), b is the bias (additive coefficient), σ(.) is the activation function, and z is the output value. Activation functions include the sigmoid function, tanh function, rectified linear unit (ReLU) (also known as the linear rectified function), etc. The parameters of each neuron, combined with the algorithm used, constitute the "parameter information" of the entire network, which is a very important part of the AI ​​model file.

[0059] In practical use, an AI model refers to a file containing elements such as network structure and parameter information. The trained AI model can be directly reused by its framework platform without repeated construction or learning, and can directly perform intelligent functions such as judgment and recognition.

[0060] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0061] Figure 5 is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application.

[0062] As shown in Figure 5, the wireless communication method 200 may include at least some of the following:

[0063] S201, the first device receives first information from the second device; wherein the first information includes at least one of the following: the intention information of the second device, and the status information of the second device.

[0064] For example, the willingness information can be used to indicate the willingness of the second device to participate in or not participate in the VFL task.

[0065] For example, the status information may be information related to the load status or service status of the second device.

[0066] S202, the first device determines, based on the first information, whether the second device participates in the target VFL task or not.

[0067] For example, the target VFL task can be a VFL task specific to a target device. A VFL task refers to a task within a longitudinal federated learning framework where multiple participants share their respective data features without directly exposing the raw data, and jointly perform inference based on a machine learning model. For example, VFL tasks include, but are not limited to, VFL-based localization tasks and VFL-based user experience evaluation tasks. It should be noted that "task" can also refer to an event, analytics, data analysis, or data analysis task, etc., all conveying the same meaning: a VFL task can be a VFL-related event, VFL-related data analysis, etc.

[0068] In this context, the target device refers to the device to which the VFL task is directed. The first device and the second device are devices that perform inference for the target VFL task. For example, the second device can perform inference based on the data corresponding to the target VFL task to obtain the intermediate result of the target VFL task; the first device can perform inference on the target VFL task based on the intermediate result obtained by the second device to obtain the inference result of the target VFL task. In one scenario, a consumer device (also known as a consumer device) initiates a target VFL task for the target device, or in other words, the consumer device sends an inference request for the target VFL task to the first device; after receiving the inference request, the first device requests the second device to infer the intermediate result of the target VFL task, obtains the intermediate result of the target VFL task from the second device, and performs inference on the target VFL task based on the intermediate result to obtain the inference result of the target VFL task.

[0069] For example, the first device determining whether the second device participates in the target VFL task or not based on the first information can be understood as: the first device determining whether to select the second device to participate in the target VFL task or not based on the first information, or it can be understood as: the first device determining whether to select the second device to participate in the target VFL task or not based on the first information. This application does not specifically limit this.

[0070] For example, when the first device determines that the second device is participating in the target VFL task, the first device sends an inference request to the second device. This inference request requests the second device to perform inference on the target VFL task. Upon receiving the inference request, the second device performs inference based on the data corresponding to the target VFL task to obtain an intermediate result. In one implementation, this intermediate result may be data features corresponding to the data of the target VFL task in the second device, such as data features extracted using mathematical methods like models. After obtaining the intermediate result of the target VFL task, the second device sends the intermediate result of the target VFL task to the first device. Upon receiving the intermediate result of the target VFL task, the first device performs inference on the target VFL task based on the intermediate result to obtain the inference result of the target VFL task. For example, the first device performs inference on the target VFL task based on intermediate results from multiple second devices to obtain the inference result of the target VFL task. It should be noted that the inference request sent by the first device to the second device may be a VFL inference request. It should also be noted that the VFL task may be VFL inference, VFL inference task, etc.

[0071] In this embodiment of the application, the first device receives first information from the second device and determines, based on the first information, whether the second device participates in the target VFL task or not, which can improve the inference efficiency of the VFL task.

[0072] Specifically, in some scenarios, the second device may be unable to obtain the task data of the target VFL task, meaning it may be unable to obtain the data of the target device associated with the target VFL task. For example, the target device may be connected to the core network but not connected to the second device or generating services on the second device. In this case, even if the second device participates in training for a VFL task of the same type as the target VFL task, the inference efficiency of the target VFL task may be reduced due to the second device's inability to obtain task data. Furthermore, if the second device is overloaded, it may be unable to participate in the inference of the target VFL task, thus reducing the inference efficiency of the VFL task. In this embodiment, the first device receives first information from the second device and, based on this first information, determines whether the second device participates in or does not participate in the target VFL task, thereby improving the inference efficiency of the VFL task.

[0073] It should be noted that this application does not specifically limit the type of the first device or the second device. The first device or the second device can be any type of device with VFL capabilities, such as a terminal, network-side device, or server. For example, devices with VFL capabilities include, but are not limited to, devices that have installed or run VFL models. For example, the first device represents a communication device with VFL capabilities, such as a communication device with VFL server capabilities, such as intelligent network elements in the network, such as NWDAF, Model Training logical function (MTLF), Analytics logical function (AnLF), or Application function (AF); the second device represents a communication device with VFL capabilities, such as a communication device with VFL client capabilities, such as intelligent network elements in the network, such as NWDAF, MTLF, AnLF, or AF. Here, AF can represent a communication device outside the core network, such as a third-party server. In one embodiment, the first communication device can be called a VFL server, and the second communication device can be called a VFL client.

[0074] In some embodiments, the intention information includes at least one of the following:

[0075] The first indication information is used to instruct the second device to participate in the target VFL task, or to instruct the second device not to participate in the target VFL task;

[0076] First-time information is used to indicate the time when the second device participates in the target VFL task;

[0077] The second time information is used to indicate the time during which the second device does not participate in the target VFL task;

[0078] First scope information is used to indicate the scope of the VFL tasks in which the second device participates;

[0079] The second range information is used to indicate the range of VFL tasks in which the second device does not participate.

[0080] For example, the first indication information is used to instruct the second device to participate in the target VFL task. This can be understood as indicating that the first indication information indicates the second device's desire to participate in the target VFL task or its willingness to participate. The first indication information is also used to instruct the second device not to participate in the target VFL task, which can be understood as indicating that the second device's desire not to participate in the target VFL task or its lack of willingness to participate. When the first indication information is used to instruct the second device to participate in the target VFL task, in one implementation, the first indication information may include the identification information of the target VFL task and an indication to instruct the second device to participate in the VFL task; in another implementation, the first indication information may specifically be used to instruct the second device to participate in any VFL task, or to instruct the second device to participate in a VFL-related process, or to instruct the second device to join a VFL. When the first indication information is used to instruct the second device not to participate in the target VFL task, in one implementation, the first indication information may include the identification information of the target VFL task and an indication to instruct the second device not to participate in the VFL task; in another implementation, the first indication information may specifically be used to instruct the second device not to participate in any VFL task, or the first indication information may specifically be used to instruct the second device not to participate in VFL-related processes, or the first indication information may specifically be used to instruct the second device to exit VFL. The VFL-related processes include, but are not limited to, VFL inference, VFL training, and VFL retraining.

[0081] For example, the first indication information is used to instruct the second device to participate in the target VFL task, which can also be understood as: the first indication information is used to instruct the second device to participate in the target VFL task. The first indication information is also used to instruct the second device not to participate in the target VFL task, which can also be understood as: the first indication information is used to instruct the second device not to participate in the target VFL task. For example, the second device can determine whether to participate in the target VFL task based on its pre-configuration. For example, a specific time period may be designated as energy-saving time, during which VFL tasks are not participated in.

[0082] For example, the time when the second device participates in the target VFL task can be understood as the time when the second device can participate in the VFL task. For example, the time of participation in the target VFL task could be 7-9 AM. The time when the second device participates in the target VFL task includes the time period or time range during which the second device participates in the target VFL task. The time when the second device does not participate in the target VFL task can be understood as the time when the second device cannot participate in the target VFL task. For example, the time when the second device does not participate in the target VFL task could be 7-9 PM. The time when the second device does not participate in the target VFL task can include the time period or time range during which the second device does not participate in the target VFL task.

[0083] For example, the scope of VFL tasks in which the second device participates includes the scope of VFL tasks that the second device expects to participate in or is willing to participate in. Optionally, the scope of VFL tasks may include one or more VFL task types. The VFL task types include, but are not limited to, VFL-based location tasks, VFL-based information evaluation tasks, etc. For example, the first scope information may be used to indicate one or more VFL task types that the second device expects to participate in or is willing to participate in. Alternatively, the first scope information may be used to indicate a whitelist of VFL task types in which the second device participates.

[0084] For example, the scope of VFL tasks that the second device does not participate in includes the scope of VFL tasks that the second device expects not to participate in or has no intention of participating in. Optionally, the VFL task scope may include one or more VFL task types. The VFL task types include, but are not limited to, VFL-based location tasks, VFL-based information assessment tasks, etc. For example, the second scope information may be used to indicate one or more VFL task types that the second device expects not to participate in or has no intention of participating in. Alternatively, the second scope information may be used to indicate a blacklist of VFL task types that the second device participates in.

[0085] For example, the first device can directly determine whether the second device participates in or does not participate in the target VFL task based on the first indication information. Alternatively, if the time range indicated by the first time range includes the time associated with the target VFL task, the first device determines that the second device participates in the target VFL task; if the time range indicated by the second time range does not include the time associated with the target VFL task, the first device determines that the second device does not participate in the target VFL task. Alternatively, if the VFL task range indicated by the first range information includes the target VFL task, the first device determines that the second device participates in the target VFL task; if the VFL task range indicated by the first range information does not include the target VFL task, the first device determines that the second device does not participate in the target VFL task.

[0086] In this embodiment, by introducing the intention information, it is helpful for the second device to control or balance the load of the second device; by refining the intention information, the flexibility of the second device in responding to the intention information can be improved.

[0087] In some embodiments, the status information includes at least one of the following:

[0088] Load information, including load parameters of the second device, or indications that the second device is overloaded;

[0089] Business information, including business parameters of the second device, or indications of excessive business of the second device;

[0090] First area information, used to indicate the geographical area where the second device is located;

[0091] Second area information is used to indicate the geographical area served by the second device.

[0092] For example, the load information refers to information related to the load status of the second device. In one implementation, the load information may include load parameters, which are parameters related to the load status of the second device, or parameters determined based on parameters related to the load status of the second device. For example, the load parameters include a load level related to the load status of the second device, and the load level may include three or more levels: high, medium, and low. The load information may include one or more load parameters. When the load parameters indicate that the load of the second device is too high, it means that the second device cannot participate in the VFL task. In another implementation, the load information may include load-related indication information, such as an indication of excessive load, for example, when the second device determines that its load is too high based on internal logic. The first device may determine whether to select the device to participate in the VFL task based on the indication of excessive load.

[0093] For example, the business information refers to information related to the business status of the second device. In one implementation, the business information includes business parameters, which are parameters related to the business status of the second device and are determined based on these parameters. For example, the business parameters include the number of services being executed, the number of services to be executed, and the types of services that the second device can execute. The service types include, but are not limited to, event services, analytics services, and VFL task services. The business information may include one or more business parameters. In another implementation, the business information may include business-related indication information, such as an indication of excessive business activity, for example, when the second device determines, based on internal logic, that its business activity is too high. The first device can determine whether to select the device to participate in the VFL task based on this indication of excessive business activity.

[0094] For example, the geographical area where the second device is located can be the geographical area covered by the second device. The geographical area served by the second device is used to indicate that the second device participates in VFL tasks associated with the geographical area served by the second device, or the geographical area served by the second device is used to indicate that the second device can collect data within the geographical area served by the second device and participate in VFL tasks based on the collected data. It is understood that when the geographical area where the second device is located or the geographical area served by the second device changes, the VFL tasks it can participate in and its scope may also change, or it may be unable to participate in related VFL operations, etc. It should be noted that the first area information and the second area information can be the same, that is, the geographical area where the second device is located is the same as the geographical area served by the second device.

[0095] In this embodiment, by refining the status information, the capability requirements of the first device on the second device can be reduced, that is, the complexity of the second device can be reduced.

[0096] In some embodiments, S202 includes:

[0097] Based on the first information, the first device determines that the second device participates in the target VFL task if at least one of the following conditions is met:

[0098] The load parameter is less than or equal to the first threshold value;

[0099] The business parameter is less than or equal to the second threshold value;

[0100] The geographical region indicated by the first area information matches the target VFL task;

[0101] The geographic region indicated by the second region information matches the target VFL task.

[0102] For example, the matching of the geographic region indicated by the first region information and the target VFL task includes at least one of the following: the geographic region indicated by the first region information includes the geographic location associated with the target VFL task, and the target device associated with the target VFL task is located within the geographic region indicated by the first region information.

[0103] For example, the geographic region indicated by the second region information and the target VFL task are matched in at least one of the following ways: the geographic region indicated by the second region information includes the geographic location associated with the target VFL task, or the target device associated with the target VFL task is located within the geographic region indicated by the second region information.

[0104] In this embodiment, by refining the status information, the first device can determine that the second device is participating in the target VFL task based on different information, which reduces the difficulty for the first device to determine that the second device is participating in the target VFL task.

[0105] In some embodiments, S202 includes:

[0106] Based on the first information, the first device determines that the second device will not participate in the target VFL task if at least one of the following conditions is met:

[0107] The load information includes an indication of excessive load.

[0108] The load information includes indications of excessive service.

[0109] The load parameter is greater than or equal to the first threshold value;

[0110] The business parameter is greater than or equal to the second threshold value;

[0111] The geographical region indicated by the first area information does not match the target VFL task;

[0112] The geographic region indicated by the second region information does not match the target VFL task.

[0113] For example, the geographical area indicated by the first area information and the target VFL task do not match, including at least one of the following: the geographical area indicated by the first area information does not include the geographical location associated with the target VFL task, or the target device associated with the target VFL task is not located within the geographical area indicated by the first area information.

[0114] For example, the geographical area indicated by the second area information and the target VFL task do not match, including at least one of the following: the geographical area indicated by the second area information does not include the geographical location associated with the target VFL task, or the target device associated with the target VFL task is not located within the geographical area indicated by the second area information.

[0115] In this embodiment, by refining the state information, the first device can determine that the second device does not participate in the target VFL task based on different information, which reduces the difficulty for the first device to determine that the second device does not participate in the target VFL task.

[0116] In some embodiments, the first information further includes at least one of the following:

[0117] The second indication information is used to indicate that the second device has the ability to participate in the target VFL task, or to indicate that the second device does not have the ability to participate in the target VFL task;

[0118] The first reason information indicates the reason why the second device cannot participate in the target VFL task;

[0119] A first threshold value is used to indicate that the first device determines that the second device participates in the target VFL task when the load parameter of the second device is less than or equal to the first threshold value, or to indicate that the first device determines that the second device does not participate in the target VFL task when the load parameter of the second device is greater than or equal to the first threshold value.

[0120] The second threshold value is used to indicate that the first device determines that the second device participates in the target VFL task when the service parameters of the second device are less than or equal to the second threshold value, or to indicate that the first device determines that the second device does not participate in the target VFL task when the service parameters of the second device are greater than or equal to the second threshold value.

[0121] For example, the second indication information is used to indicate that the second device has the capability to participate in the target VFL task, which can be understood as: the second indication information is used to indicate that the second device can or is able to participate in the target VFL task. The second indication information is also used to indicate that the second device cannot participate in the target VFL task, which can be understood as: the second indication information is used to indicate that the second device cannot participate in the target VFL task.

[0122] For example, the first threshold value can be used to indicate that, when the load parameter of the second device is less than or equal to the first threshold value, the first device determines that the second device expects or intends to participate in the target VFL task; or it can be used to indicate that, when the load parameter of the second device is greater than or equal to the first threshold value, the first device determines that the second device does not expect or does not intend to participate in the target VFL task. The second threshold value can be used to indicate that, when the service parameter of the second device is less than or equal to the second threshold value, the first device determines that the second device expects or intends to participate in the target VFL task; or it can be used to indicate that, when the service parameter of the second device is greater than or equal to the second threshold value, the first device determines that the second device does not expect or does not intend to participate in the target VFL task.

[0123] It is understood that the first threshold is used by the first device to determine whether the second device expects or intends to participate in the target VFL task when the load parameter of the second device is less than or equal to the first threshold, or by the first device to determine whether the second device does not expect or intends to participate in the target VFL task when the load parameter of the second device is greater than or equal to the first threshold. The second threshold can be used by the first device to determine whether the second device expects or intends to participate in the target VFL task when the service parameter of the second device is less than or equal to the second threshold, or by the first device to determine whether the second device does not expect or intends to participate in the target VFL task when the service parameter of the second device is greater than or equal to the second threshold.

[0124] For example, the reasons why the second device cannot participate in the target VFL task include at least one of the following: inability to obtain relevant data from the target device, inability to reach the target device, privacy settings of the target device, the target device being outside the geographical area where the second device is located, or the target device being outside the geographical area served by the second device. It should be noted that the relevant data from the target device refers to the data used for inference of the intermediate results of the target VFL, that is, the input data required by the second device when inferring the intermediate results of the target VFL. Privacy settings of the target device may include user consent settings, etc.

[0125] For example, the first information may also include the identification information of the target VFL task.

[0126] In this embodiment, by enriching the first information, the inference efficiency of the VFL task can be improved.

[0127] In some embodiments, prior to S201, the method 200 further includes:

[0128] The first device sends a first request to the second device;

[0129] Wherein, the first request is used to request to obtain the first information, or the first request is used to request the second device to prepare to participate in the target VFL task, or the first request is used to request the second device to participate in the target VFL task.

[0130] For example, if the first request is used to request the acquisition of the first information or to request the second device to prepare to participate in the target VFL task, after receiving the first request, the second device sends the first information to the first device; after receiving the first information, the first device determines whether to participate in the target VFL task or not based on the first information. It should be noted that the VFL task can also be VFL inference, VFL inference task, etc. It is understood that the first request can also be used to request the second device to prepare to participate in VFL inference, etc., or the first request message can be a VFL inference preparation request, etc.

[0131] For example, if the first request is used to request the second device to participate in the target VFL task, after receiving the first request, the second device determines whether it participates in the target VFL task. If it is determined that the second device participates in the target VFL task, the second device infers the intermediate results of the target VFL task to obtain the intermediate results of the target VFL task and sends the intermediate results of the target VFL task to the first device. If it is determined that the second device does not participate in the target VFL task, the second device sends the first information to the first device.

[0132] In this embodiment, by introducing the first request, the first device is able to obtain the first information, thereby ensuring the inference efficiency of the VFL task.

[0133] In some embodiments, the first request includes at least one of the following:

[0134] The third instruction information is used to instruct the second device to prepare to participate in the target VFL task;

[0135] The fourth instruction information is used to instruct the second device to provide feedback on at least one of the following: the intention information, the status information.

[0136] For example, if the first request is used to request the acquisition of the first information or the first request is used to request the second device to prepare to participate in the target VFL task, the first request includes at least one of the following: the third indication information and the fourth indication information.

[0137] For example, the first request may also include at least one of the following:

[0138] The target VFL task belongs to the task type.

[0139] The identification information of the target VFL task, such as the VFL correlation ID, is used to indicate the target VFL task. The second device can use this identification information to determine the model and / or data to be used.

[0140] The time or region information corresponding to the target VFL task.

[0141] The identification information of the target device corresponding to the target VFL task.

[0142] The identification information of the model corresponding to the target VFL task.

[0143] In this embodiment, by refining the information in the first request, the second device can be guided to promptly provide the first information after receiving the first request, enabling the first device to obtain the first information in a timely manner, thereby ensuring the inference efficiency of the VFL task.

[0144] The solution provided in this application will be described below with reference to specific embodiments.

[0145] Example 1:

[0146] In this embodiment, the second device sends first information to the first device, and the first device determines, based on the first information, whether the second device participates in the target VFL task or not.

[0147] In this embodiment, the first or second device can be any type of device with VFL capabilities, such as a terminal, network-side device, or server. For example, devices with VFL capabilities include, but are not limited to, devices with VFL models installed or running. For instance, the first device represents a communication device with VFL capabilities, such as a communication device with VFL server capabilities, or an intelligent network element in the network, such as NWDAF, Model Training logical function (MTLF), Analytics logical function (AnLF), or Application function (AF). The second device represents a communication device with VFL capabilities, such as a communication device with VFL client capabilities, or an intelligent network element in the network, such as NWDAF, MTLF, AnLF, or AF. Here, AF can represent a communication device outside the core network, such as a third-party server. In one implementation, the first communication device can be called a VFL server, and the second communication device can be called a VFL client.

[0148] Figure 6 is a schematic flowchart of a wireless communication method 310 according to an embodiment of this application.

[0149] As shown in Figure 6, the wireless communication method 310 may include:

[0150] S311, the first and second devices complete VFL training.

[0151] The first and second devices interact to complete VFL training, which refers to the training of the VFL model. Specifically, before completing VFL training, the first device can find and select the second device to participate in the VFL training through a device search process. The first and second devices interact, such as sample alignment, to confirm the training data to be used. The first and second devices then perform VFL training based on the aligned samples.

[0152] S312a, the second device sends the first information to the first device.

[0153] S312b, the second device sends the first information to the first device via NEF.

[0154] The second device sends a first message to the first device. For example, the second device may determine whether it can participate in the subsequent VFL inference process based on its internal logic or pre-configuration, and send the first message to the first device to notify it of its eligibility. For instance, if the second device determines that it cannot participate in the subsequent VFL inference process due to its load or excessive subsequent task schedule, it sends the first message to inform the first device that it cannot participate. It should be noted that when the second device is a non-core network device / element, such as when the second device is an untrusted AF, the second device sends the first message to the first device via NEF.

[0155] The first information includes at least one of the following: the second device's willingness information and the second device's status information. The willingness information can be used to indicate whether the second device intends to participate in or not participate in a VFL task. The status information can be information related to the second device's load status or service status.

[0156] Optionally, the intention information includes at least one of the following:

[0157] 1. A first indication message, used to indicate that the second device participates in the target VFL task, or to indicate that the second device does not participate in the target VFL task.

[0158] The first indication information is used to instruct the second device not to participate in the target VFL task, which can also be understood as: the first indication information is used to instruct the second device not to participate in the target VFL task. When the first indication information is used to instruct the second device not to participate in the target VFL task, the first indication information can specifically be used to instruct the second device not to participate in any VFL task, or the first indication information can specifically be used to instruct the second device not to participate in VFL-related processes, or the first indication information can specifically be used to instruct the second device to exit VFL. VFL-related processes include, but are not limited to, VFL inference, VFL training, and VFL retraining.

[0159] The first device can determine, based on the first indication information, whether the second device participates in the target VFL task or not.

[0160] 2. First time information, used to indicate the time when the second device participates in the target VFL task.

[0161] The time during which the second device participates in the target VFL task can be understood as the time during which the second device can participate in the VFL task. For example, it can participate in the VFL task between 7 and 9 a.m. The time during which the second device participates in the target VFL task includes the time period or range during which the second device participates in the target VFL task.

[0162] 3. Second time information, used to indicate the time during which the second device does not participate in the target VFL task.

[0163] The time during which the second device does not participate in the target VFL task can be understood as the time during which the second device is unable to participate in the target VFL task. For example, not participating in a VFL task between 7 PM and 9 PM. The time during which the second device does not participate in the target VFL task can include the time period or range during which the second device does not participate in the target VFL task.

[0164] 4. First scope information, used to indicate the scope of the VFL task in which the second device participates.

[0165] The scope of VFL tasks in which the second device participates includes the scope of VFL tasks that the second device expects to participate in or is willing to participate in. Optionally, the scope of VFL tasks may include one or more VFL task types. The VFL task types include, but are not limited to, VFL-based location tasks and VFL-based information evaluation tasks. For example, the first scope information may be used to indicate one or more VFL task types that the second device expects to participate in or is willing to participate in. Alternatively, the first scope information may be used to indicate a whitelist of VFL task types in which the second device participates.

[0166] 5. Second range information, used to indicate the range of VFL tasks in which the second device does not participate.

[0167] The scope of VFL tasks that the second device does not participate in includes the scope of VFL tasks that the second device expects not to participate in or has no intention of participating in. Optionally, the VFL task scope may include one or more VFL task types. The VFL task types include, but are not limited to, VFL-based location tasks and VFL-based information assessment tasks. For example, the second scope information may be used to indicate one or more VFL task types that the second device expects not to participate in or has no intention of participating in. Alternatively, the second scope information may be used to indicate a blacklist of VFL task types that the second device participates in.

[0168] Optionally, the status information includes at least one of the following:

[0169] 1. Load information, including load parameters of the second device, or indications that the second device is overloaded;

[0170] The load information refers to information related to the load status of the second device. In one implementation, the load information may include load parameters, which are parameters related to the load status of the second device, or parameters determined based on parameters related to the load status of the second device. For example, the load parameters may include a load level related to the load status of the second device, and the load level may include three or more levels: high, medium, and low. The load information may include one or more load parameters. When the load parameters indicate that the load of the second device is too high, it means that the second device cannot participate in the VFL task. In another implementation, the load information may include load-related indication information, such as an indication of excessive load, for example, when the second device determines that its load is too high based on internal logic. The first device can determine whether to select the device to participate in the VFL task based on this excessive load indication information.

[0171] 2. Service information, including service parameters of the second device, or indications of excessive service on the second device;

[0172] The business information refers to information related to the business status of the second device. In one implementation, the business information includes business parameters, which are parameters related to the business status of the second device and are determined based on these parameters. For example, the business parameters include the number of services currently being executed, the number of services to be executed, and the types of services that the second device can execute. The service types include, but are not limited to, event services, analytics services, and VFL task services. The business information may include one or more business parameters. In another implementation, the business information may include business-related indication information, such as an indication of excessive business activity, for example, when the second device determines, based on internal logic, that its business activity is too high. The first device can then determine whether to select this device to participate in the VFL task based on this excessive business activity indication information.

[0173] 3. First area information, used to indicate the geographical area where the second device is located.

[0174] The geographical area where the second device is located can be the geographical area covered by the second device.

[0175] 4. Second area information, used to indicate the geographical area served by the second device.

[0176] The geographic area served by the second device is used to indicate that the second device participates in VFL tasks associated with the geographic area served by the second device.

[0177] It is understandable that when the geographical area where the second device is located or the geographical area served by the second device changes, the VFL tasks and scope that it can participate in may also change, or it may be unable to participate in related VFL operations.

[0178] It should be noted that the first information may also include other information, such as the identification information of the target VFL task. This embodiment does not specifically limit this.

[0179] S313, the first device receives an inference request from another device.

[0180] The first device can receive inference requests from other devices, requesting to perform inference on a target VFL task for the target device, or requesting to obtain the inference result of the target VFL task for the target device. The other devices can be consumer devices, and the target device can be a target UE or a target network element, etc. It is understood that the inference result of the target VFL task is related to the target device; for example, the inference result of the target VFL task may be a prediction result of relevant data of the target device. Specifically, it may include at least one of the following:

[0181] 1. The task type to which the target VFL task belongs.

[0182] The task types mentioned include data analysis types, etc.

[0183] 2. Identification information of the target VFL task.

[0184] For example, the identification information includes a VFL correlation ID, which indicates the target VFL task. The second device can use this identification information to determine the model and / or data to be used.

[0185] 3. The time information or region information corresponding to the target VFL task.

[0186] The time information corresponding to the target VFL task can be used to indicate the time limit of the target VFL task. The region information corresponding to the target VFL task can be used to indicate the region limit of the target VFL task.

[0187] 4. Identification information of the target device corresponding to the target VFL task.

[0188] 5. Identification information of the model corresponding to the target VFL task.

[0189] S314, The first device determines to execute the target VFL task.

[0190] After receiving an inference request from another device, the first device determines to perform VFL inference based on the information in the inference request.

[0191] S315, the first device determines, based on the first information, whether the second device will participate in the target VFL task or not.

[0192] In one implementation, the first device determines whether the second device will participate in or not participate in the target VFL task based on the intention information sent by the second device.

[0193] For example, the first device can directly determine whether the second device participates in or does not participate in the target VFL task based on the first indication information. Alternatively, if the time range indicated by the first time range includes the time associated with the target VFL task, the first device determines that the second device participates in the target VFL task; if the time range indicated by the second time range does not include the time associated with the target VFL task, the first device determines that the second device does not participate in the target VFL task. Alternatively, if the VFL task range indicated by the first range information includes the target VFL task, the first device determines that the second device participates in the target VFL task; if the VFL task range indicated by the first range information does not include the target VFL task, the first device determines that the second device does not participate in the target VFL task.

[0194] In one implementation, the first device determines whether the second device participates in the target VFL task or not, based on the status information sent by the second device.

[0195] For example, based on the first information, the first device determines that the second device is involved in the target VFL task if at least one of the following conditions is met:

[0196] The load parameter is less than or equal to the first threshold value;

[0197] The business parameter is less than or equal to the second threshold value;

[0198] The geographical region indicated by the first area information matches the target VFL task;

[0199] The geographic region indicated by the second region information matches the target VFL task.

[0200] Wherein, the matching of the geographic region indicated by the first region information and the target VFL task includes at least one of the following: the geographic region indicated by the first region information includes the geographic location associated with the target VFL task, and the target device associated with the target VFL task is located within the geographic region indicated by the first region information. The matching of the geographic region indicated by the second region information and the target VFL task includes at least one of the following: the geographic region indicated by the second region information includes the geographic location associated with the target VFL task, and the target device associated with the target VFL task is located within the geographic region indicated by the second region information.

[0201] For example, based on the first information, the first device determines that the second device will not participate in the target VFL task if at least one of the following conditions is met:

[0202] The load information includes an indication of excessive load.

[0203] The load information includes indications of excessive service.

[0204] The load parameter is greater than or equal to the first threshold value;

[0205] The business parameter is greater than or equal to the second threshold value;

[0206] The geographical region indicated by the first area information does not match the target VFL task;

[0207] The geographic region indicated by the second region information does not match the target VFL task.

[0208] The mismatch between the geographical region indicated by the first regional information and the target VFL task includes at least one of the following: the geographical region indicated by the first regional information does not include the geographical location associated with the target VFL task; or the target device associated with the target VFL task is not located within the geographical region indicated by the first regional information. The mismatch between the geographical region indicated by the second regional information and the target VFL task includes at least one of the following: the geographical region indicated by the second regional information does not include the geographical location associated with the target VFL task; or the target device associated with the target VFL task is not located within the geographical region indicated by the second regional information.

[0209] It should be noted that the first device determines whether the second device participates in the target VFL task based on the first information. This can also be understood as the first device determining which second device will participate in the target VFL task based on the first information sent by multiple second devices. For example, the first device selects the second device to participate in the target VFL task from among the second devices participating in VFL training.

[0210] For example, if the first information sent by a second device includes a first indication, and the first indication is used to indicate that the second device will not participate in the target VFL task; or if the load information in the first information includes a load level, and the load level indicates that the load level is high; or if the load information in the first information includes an indication that the load is too high; or if the service information in the first information includes an indication that there are too many services, the first device can remove this second device from the selection of second devices to participate in the target VFL task, that is, not select this second device to participate in the target VFL task.

[0211] For example, when a second device sends a first message including a first indication message, and the first indication message is used to indicate that the second device participates in the target VFL task, or when the load information in the first message includes a load level, and the load level indicates that the load level is low, the first device can select this second device to participate in the target VFL task.

[0212] It should be noted that if the second device does not send the first information, the first device can choose to select the second device or not select the second device to participate in the target VFL task.

[0213] S316, The first device and the second device participating in the target VFL task execute the target VFL task.

[0214] The first device interacts with the second device, which is determined to participate in the target VFL task, to complete the VFL inference process and generate the final inference result. Specifically, the first device sends an inference request to the second device participating in the target VFL task, requesting the second device to infer the intermediate results of the target VFL task. After receiving the inference request, the second device infers the intermediate results of the target VFL task to obtain the intermediate result of the target VFL task and sends the intermediate result of the target VFL task to the first device. After receiving the intermediate result of the target VFL task, the first device infers the target VFL task based on the intermediate result of the target VFL task to obtain the inference result of the target VFL task. For example, the first device infers the target VFL task based on the intermediate results from multiple second devices participating in the target VFL task to obtain the inference result of the target VFL task.

[0215] It should be noted that when generating the final inference result, the first device can assign different weights to different second devices, thus aggregating the final inference result (e.g., aggregating intermediate results from multiple second devices) based on these weights. For example, if the first device cannot select a satisfactory second device (e.g., some second devices may not be able to participate in the target VFL task), the first device can perform inference based on the intermediate results fed back by other second devices. However, the priority / weight of the intermediate results fed back by different second devices may be inconsistent. It should also be noted that the first device can decide to retrain before or after executing the target VFL task, for example, if too many second devices are unable to participate in the target VFL task or the inference results are too poor.

[0216] Example 2:

[0217] In this embodiment, Embodiment 2 is similar to Embodiment 1, except that in Embodiment 2, the first device first sends a first request to the second device so that the second device can determine whether it can participate in the target VFL task or whether it can perform VFL inference for the target VFL task.

[0218] Figure 7 is a schematic flowchart of a wireless communication method 320 according to an embodiment of this application.

[0219] As shown in Figure 7, the wireless communication method 320 may include:

[0220] S321, the first and second devices complete VFL training.

[0221] The first and second devices interact to complete VFL training, which refers to the training of the VFL model. Specifically, before completing VFL training, the first device can find and select the second device to participate in the VFL training through a device search process. The first and second devices interact, such as sample alignment, to confirm the training data to be used. The first and second devices then perform VFL training based on the aligned samples.

[0222] S322, the first device receives an inference request from another device.

[0223] The first device can receive inference requests from other devices, requesting to perform inference on a target VFL task for the target device, or requesting to obtain the inference result of the target VFL task for the target device. The other devices can be consumer devices, and the target device can be a target UE or a target network element, etc. It is understood that the inference result of the target VFL task is related to the target device; for example, the inference result of the target VFL task may be a prediction result of relevant data of the target device. Specifically, it may include at least one of the following:

[0224] 1. The task type to which the target VFL task belongs.

[0225] The task types mentioned include data analysis types, etc.
