The method for determining the candidate member provided by the embodiment of the application is described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.
Federal learning includes both horizontal federal learning and vertical federal learning, wherein the nature of horizontal federal learning is a combination of samples that is applicable to scenarios where the inter-participant performance is the same but the touching customers are different, i.e., there is a large overlap in features, and there is a small overlap in samples, such as Core Network (CN) domain and radio access network (Radio Access Network, RAN) domain within a communication network serving the same service (e.g., mobility management (mobility management, MM), session management (session management, SM) service, a certain service) of different users (e.g., each terminal, i.e., sample is different). By combining the same data characteristics of different samples of the participants, the transverse federation increases the number of training samples, thereby yielding a better model.
The essence of longitudinal federal learning is feature combination, which is suitable for the scene that the sample overlap is more and the feature overlap is less, such as different services (e.g. MM, SM service, i.e. features are different) of the same user (e.g. terminal, i.e. sample is the same) served by the CN domain and the RAN domain in the communication network. By combining different data features of the common sample of the participants, the longitudinal federation increases the feature dimension of the training sample and results in a better model.
In the federal learning system, the system comprises a manager (server) and a plurality of participants, wherein the manager is used for sending a model to each participant, updating the model according to the feedback result of each participant, and sending the updated model to each participant again for the next model training. Each participant has respective data, and in order not to send local data to other people, each participant uses a model sent by a manager to train locally and returns the model to the manager for model updating.
By way of example, the process of model training may include the steps of:
step 1: the participants each download the latest model from the manager (server);
step 2: each participant trains a model by using local data, encrypts gradients and uploads the gradients to a manager (server), and the manager (server) aggregates gradient update model parameters of each participant;
step 3: the manager (server) returns the updated model to each participant;
step 4: each participant updates its own model.
And (3) performing multiple iterations/model updating in the steps 2 to 4, and completing model training under certain conditions (for example, after the number of iterations for a certain number of times is completed or the calculated value of the loss function of the model is lower than a preset value).
A network data analysis function network element (network data analytic function, NWDAF) is introduced in 5 GS. The NWDAF may collect data from each network element, network management system, etc. of the core network to perform big data statistics, analysis, or intelligent data analysis, to obtain analysis or prediction data at the network side, so as to assist each network element to more effectively control terminal access according to the data analysis result.
In the method for determining the candidate members, the data of other network elements can be collected through the NWDAF and analyzed, so that the participated members suitable for federal learning are screened out according to screening information and data analysis results, and the federal learning efficiency is improved.
In the present application, "determination of candidate members" may be understood as "determination of candidate members that can participate in federal learning".
Fig. 2 is a flow chart of a method for determining candidate members provided by the present application, and the method for determining candidate members provided by the embodiment of the present application is described below with reference to fig. 2. As shown in fig. 2, the method includes:
step 201: the first network element receives the request message sent by the second network element.
The execution main body of the candidate member determination method provided by the embodiment of the application is a first network element, and the first network element can be implemented in various forms. For example, the first network element described in the embodiment of the present application may include NWDAF, and of course, may be other network elements capable of collecting data from each network element, network management system, etc. of the core network to perform big data statistics, analysis, or intelligent data analysis. The second network element may comprise a task consumer network element, which may be, for example, an application function network element (application function, AF), a base station, a terminal, etc., or a device, which may also be a third party server.
Wherein, the request message includes screening information, and the screening information includes at least one of the following: time period, algorithm type, accuracy threshold, wireless access system, signal quality requirement, flow range, member type information, quantity information, region information and federal learning type information. Based on screening information of different dimensions, more proper participating members can be screened, so that the efficiency of federal learning is improved.
The time period is used for indicating an optional time period for performing the federal learning, and the time period may be a certain time period in the past or may be a future time period, and it is understood that if the time period is a future time period, the first network element predicts the networking state of each member in the future time period according to the acquired historical data. The networking state includes a state of a connected network and a state of an unconnected network. It should be appreciated that the time period is typically flexibly set according to the time period during which federal learning is actually performed.
The algorithm type is used for indicating the algorithm type of model training required to be supported by the federal learning, and comprises the algorithm type supported by each member and relevant to the artificial intelligence (artificial intelligence, AI) data analysis task such as 'deep learning algorithm', 'linear regression algorithm', and the like. It should be appreciated that members supporting the type of algorithm matching the function will typically be selected as participating members for federal learning based on the function of the model.
The precision threshold is used for indicating the precision requirement of model training to be met in the federal learning, and comprises precision values which can be achieved by models generated by each member after training, such as the accuracy of the models, and can be understood as the percentage of model prediction or judgment accuracy. It should be appreciated that in order to ensure accuracy of federal learning, some members with higher accuracy are typically selected as participating members of federal learning.
The wireless access system is used for indicating the wireless access system to be selected for federal learning, and comprises modes of connecting or accessing each member to a communication network, such as a WLAN (similar to WiFi) connected with non-3GPP, 5g and 4g networks connected with 3GPP, and the like. It will be appreciated that in order to ensure stability of federal learning, and to reduce traffic consumption, some members connected to WLAN or WiFi are typically selected as participating members of federal learning.
And the signal quality requirement is used for indicating the wireless signal quality requirement when the federal learning is performed. The signal quality requirements may include a threshold of network signal strength and/or a threshold of stability when the respective member connects to the communication network, etc. The signal quality requirements include WLAN network signal quality requirements, may also include 5G NR network signal quality requirements, and may also include 4G long term evolution (Long Term Evolution, LTE) network signal quality requirements. The signal quality requirement is also understood to be a minimum requirement for the proportion of time that keeps the signal strength above a certain value, e.g. the signal strength can reach the threshold requirement for at least 90% of the time. It should be appreciated that in order to ensure stability of federal learning, members with higher signal quality (e.g., stronger network signal strength and better stability) are typically selected as participating members of federal learning.
Where WLAN is connected, the signal quality may be represented by the mean, variance, etc. of the received signal strength indication (Received Signal Strength Indication, RSSI) or the round-trip time (RTT) of the signal.
The traffic range is used for indicating the traffic usage range requirement of the candidate member, and is information such as the traffic value requirement consumed by each member in a preset time period, the number of the uploaded and downloaded traffic, and the like, and can be accumulated usage of the UE. It should be appreciated that in order to alleviate the stress of individual participating members in federal learning, some members are typically selected to have a stable network state and a low traffic consumption as participants in federal learning.
The member type information is used for indicating the type requirement of the candidate member participating in the federal learning, and the member type information can be understood as the type of the candidate member participating in the federal learning at this time, for example, a terminal, a core network element (such as NWDAF), a base station, or the like.
An area of interest (AOI) for indicating the area in which the candidate member is located, the AOI may be the area in which the candidate member participating in federal learning is located, or an area of interest, or an area range of interest, which may be latitude and longitude, or one or more cells/Tracking Areas (TAs), etc.
And the quantity information is used for indicating the quantity requirement of the candidate members, and can be understood as the quantity of the members participating in federal learning, namely the quantity of the candidate members required to be determined by the first network element. The first network element may determine the number of candidate network elements. The number information may be the minimum number of required candidate members, i.e. the determined number of candidate members cannot be smaller than the minimum number of required candidate members. The number information may also be the maximum number of required candidate members, i.e. the number of determined candidate members cannot be greater than the maximum number of required candidate members.
And the type information of the federal study is used for indicating that the federal study belongs to the longitudinal federation or the transverse federation. Optionally, the request message may further include indication information, where the indication information is used to indicate that a determination task of a candidate member participating in federal learning is performed, that is, the task is selected by a member for federal learning or federal learning, and after the first network element receives the request message, based on the request message or based on the indication information in the request message, the first network element may learn that the determination task of the candidate member participating in federal learning needs to be performed.
Step 202: the first network element determines one or more first devices as candidate members that can participate in federal learning based on the screening information.
In this step, after receiving the request message, the first network element performs screening from a plurality of second devices according to screening information in the request message, so as to determine one or more first devices that meet the screening information, and determine the first devices as candidate members that can participate in federal learning.

In addition, when the device type is included in the filtering information, the first device is a first device of the device type, and when the region information is included in the filtering information, the first device is a first device in the region information.
It should be understood that in the case where at least two items of screening information are included, the first device is a device that satisfies the respective at least two items of screening information. For example, in the case where the time period and the supported algorithm type are included in the filtering information, the first device is a first device that is in a networking state for the time period and supports the algorithm type. The case that the filtering information includes at least two other information is similar to the case that the filtering information includes a time period and a supported algorithm type, and will not be described herein.
In the above embodiment, the first device satisfying the screening information may be screened from the at least one second device by the screening information as a candidate network element, so that a member suitable for participating in federal learning may be selected, which is helpful for improving efficiency of federal learning training.
Optionally, when determining the candidate member, the first network element may determine a data type corresponding to the screening information, acquire attribute information corresponding to each of the at least one device from the at least one third network element based on the data type, and determine the candidate member according to the attribute information and the screening information.
Optionally, the data types include at least one of the following networking information, a corresponding time period, an algorithm type, a wireless access system, a signal quality, and a traffic.
Specifically, in the case that the screening information includes a time period, the data type corresponding to the screening information is networking information and the time period corresponding to the networking state, in the case that the screening information includes a supported algorithm type, the data type corresponding to the screening information is algorithm type, in the case that the screening information includes an accuracy threshold, the data type corresponding to the screening information is accuracy information, in the case that the screening information includes a wireless access system, the data type corresponding to the screening information is wireless access system, in the case that the screening information includes a signal quality threshold, the data type corresponding to the screening information is signal quality, in the case that the screening information includes a traffic range, the data type corresponding to the screening information is traffic, and in the case that the screening information includes a member type, the data type corresponding to the screening information is a device type. In the case where the filtering information includes area information, the data type corresponding to the filtering information is location information.
It will be appreciated that in the case where the member type is included in the screening information, the member type is different, that is, the screening information included in the request message is different, that is, the screening information is related to the member type. For example, if the member type includes a terminal, the screening information may include at least one of a time period, a supported algorithm type, an accuracy threshold, a radio access scheme and signal quality threshold, a traffic range, and area information. If the member type includes a network-side device, such as a base station or a core network device, the screening information may include at least one of a supported algorithm type, an accuracy threshold.
After determining the data type, the first network element acquires attribute information corresponding to each of at least one second device from at least one third network element based on the data type. Wherein the third network element comprises a plurality of different network elements, it is understood that the attribute information to be acquired is different, and the first network element acquires the attribute information from the different third network elements. For example: the first network element obtains information such as the time when the terminal is connected to the WLAN, whether the terminal is connected to the WLAN, etc. from the third network element session management function (session management function, SMF). The first network element obtains information such as signal quality of the WLAN connection from a third network element, which may be a network management device, for example, operation management and maintenance (operation administration and maintenance, OAM), obtains algorithms and accuracy supported by each candidate network element from a third network element unified data management function (unified data management, UDM) or from a third network element data collection application function (data collection-application function, DC-AF), obtains traffic information of the terminal from a third network element user plane function (the user plane function, UPF), or the like, or the first network element obtains UE accumulated usage information from an SMF or a charging function (Charging Function, CHF).
It is understood that in the case where the data type includes networking information and corresponding time periods, the attribute information is a current networking state corresponding to each of the at least one device, and a time in the networking state, such as whether to connect to the network, in which time period the networking state is in, and the like. In the case that the data type includes an algorithm type, the attribute information is an algorithm that can be currently supported by at least one device corresponding to the data type, such as whether a deep learning algorithm is supported, whether a linear regression algorithm is supported, and the like. In the case that the data type includes precision information, the attribute information is the currently supported precision corresponding to at least one device, such as the precision that can be achieved by the model after the model is trained by each device. In the case that the data type includes a wireless access system, the attribute information is a network system type to which at least one device is currently connected, such as WLAN, 5G network, etc. that is currently connected. In case the data type comprises signal quality, the attribute information is the signal quality of the network currently accessed by the at least one second device or the signal quality of the network accessed within a preset time period. And when the data type comprises the traffic information, the attribute information is the traffic consumed in a preset time period corresponding to each of the at least one second device. In case the data type comprises a device type, the attribute information is a type to which at least one second device corresponds, such as a terminal, a base station or a core network device, respectively. In case the data type comprises location information, the attribute information is the location where the at least one second device is located, such as the geographical location where it is currently located, or the cell or TA where it is located, etc.
After the attribute information is acquired, matching the attribute information and the screening information corresponding to each of the at least one second device, so as to determine candidate members according to the screening information, for example, the first device meeting the screening information can be determined as the candidate member.
For example, assume that the filtering information includes a device type of a terminal, an area of a cell, an a period, and a wireless access system of WiFi connected to non-3 GPP. The first network element obtains the corresponding attribute information according to the screening information, and selects the terminal which is in the cell A, is in the networking state in the time period A and is connected with the WiFi of the non-3GPP as a candidate member according to the obtained attribute information.
In this embodiment, the first network element obtains the data type corresponding to the screening information, and obtains the attribute information of each second device from at least one third network element, so that candidate members are determined based on the attribute information and the screening information, and candidate members suitable for participating in federal learning can be determined from at least one second device through preset screening information, so that the efficiency of federal learning can be improved.
In one possible implementation, the first network element may directly determine the device that satisfies the screening information as a candidate member, and default that all candidate network elements that satisfy the screening information may participate in federal learning, and the first network element may send the identification of all candidate members that satisfy the screening information to the second network element.
In another possible implementation manner, in order to screen out more suitable participants, the first network element may also screen based on willingness information of each second device when determining candidate members according to the attribute information and the screening information. The first network element may obtain first indication information from the third network element, and determine, from the second device, one or more first devices as candidate members according to the screening information and the first indication information, where the first indication information is used to indicate willingness information of each device to participate in federal learning, and the willingness information indicates whether each device is willing to participate in federal learning.
The first device is a device which satisfies screening information and is willing to participate in federal learning.
For example, each device corresponds to its own first indication information, and for a certain device, the corresponding first indication information is 0, which indicates that the device is willing to participate in federal learning, and for a case that the first indication information is 1, the device is not willing to participate in federal learning, or may indicate that the device is willing to participate in federal learning, and for a case that the first indication information is 1, the device is not willing to participate in federal learning. Of course, the first indication information may also use other values to represent willingness information of each device to participate in federal learning.
After the first network element acquires the first indication information, the attribute information of each device is matched with the screening information, and the device which satisfies the screening information and indicates the willingness to participate in federal learning by the first indication information is determined as a candidate member.
In this embodiment, the first network element screens, according to the screening information and the first indication information, the device that satisfies the screening information and is willing to participate in federal learning as a candidate member, thereby helping to improve the efficiency of federal learning in the following.
Optionally, when the first network element determines the candidate member from the second devices according to the screening information and the first indication information, the first network element may further acquire capability information of each second device participating in federal learning from the third network element, so as to determine the candidate member according to the screening information, the first indication information and the capability information.

Optionally, the first network element may further obtain capability information of each device for participating in federal learning from the third network element, so as to match attribute information of each device with screening information, and determine that the first indication information indicates a device willing to participate in federal learning and the capability information participating in federal learning meets the screening information, which is a candidate member, thereby improving efficiency of performing federal learning subsequently.

For example, if the filtering information includes a supported algorithm type, and the supported algorithm type is a deep learning algorithm, the first network element screens out 80 devices that are originally involved in federal learning based on the first indication information, and the first network element may further screen out, based on the algorithm information that is acquired from the third network element and that can be supported by the 80 devices involved in federal learning, if 50 devices can support both the deep learning algorithm and the linear regression algorithm when participating in federal learning, and 30 devices can support only the deep learning algorithm when participating in federal learning, the first network element may further screen out, as candidate network elements, the first device that can support both the deep learning algorithm and the linear regression algorithm based on the algorithm type that can be supported when participating in federal learning.
It should be appreciated that where the capability information includes other information, the implementation is similar to the implementation where the capability information includes the types of algorithms that can be supported by participating in federal learning, and will not be described in detail herein.
The first network element can acquire willingness information and capability information of each device to participate in federal learning from the third network elements, wherein the UDM/DCAF/NRF is the network element with the capability of storing energy.
Optionally, the request message sent by the second network element further includes second indication information, where the second indication information is used to indicate a service type corresponding to federal learning. When determining the candidate member, the first network element may determine one or more first devices as the candidate member from a plurality of second devices according to the screening information and the second indication information, where the first devices are devices that can support a service corresponding to the service type.
Specifically, the second indication information may be an analytical ID, which is used to indicate a service type corresponding to federal learning. Among the data analysis tasks (i.e., other tasks for which NWDAF is responsible), the analytical ID may be: "UE mobility" is used to indicate that this task is an analysis task related to UE mobility, "NF load" is used to indicate that this task is an analysis task related to network element load.
In general, in the case that the service types corresponding to federal learning are different, the selected candidate members may be different, so when the first network element selects the candidate member, the first device capable of supporting the service corresponding to the service type from the plurality of second devices may also be selected as the candidate member according to the screening information and the service type indicated by the analytical ID. Such as: the second indication information is used for indicating that the service type corresponding to federal learning is an analysis task related to the mobility of the terminal, and the selected first device is a device capable of supporting the analysis task related to the mobility of the terminal.
In this embodiment, candidate members are further screened according to the service types corresponding to federal learning, so that the accuracy of the selected candidate members can be improved, and the training efficiency of federal learning and the accuracy of the trained model are improved.

and the first network element determines candidate members which can participate in federal learning from the first equipment according to the network state information corresponding to the first equipment and the screening information, and the network state information corresponding to the candidate members is matched with the screening information.
It should be noted that, the first network element may obtain the network state information corresponding to the first device from a third device, where the third device may be AMF, UDM, NRF, PCF, RAN or an operation, administration and maintenance device (OAM Operation Administration and Maintenance, OAM).

Specifically, when the request message includes ordering indication information, the first network element performs ascending or descending order ordering on the determined candidate members according to the second information in the ordering indication information after determining the candidate members. For example, the ranking may be performed in ascending or descending order according to the signal quality of the candidate members, or may be performed in ascending or descending order according to the accuracy information of the candidate members, or may be performed in ascending or descending order according to the traffic information of the candidate members.
When the first network element sends the response message to the second network element, the identification sequence of the candidate members in the response message is the sequence obtained after the second information is ordered.
In this embodiment, the first network element ranks the determined candidate members according to the second information, so that after receiving the identification information of the candidate members sent by the first network element, the second network element further screens the candidate members more meeting the requirements of itself according to the ranking information to participate in subsequent federal learning, thereby improving the efficiency of federal learning.

Specifically, in the case that the request message includes grouping indication information, after determining the candidate member, the first network element groups the determined candidate member according to third information in the grouping indication information. For example, the candidate members may be grouped by the region in which they are located, such as grouping candidate members in the same region into a group, or the like. The grouping may be performed according to a time period in which the candidate members are in a networking state, for example, the grouping may be performed according to an algorithm type supported by the candidate members in the same time period, for example, the grouping may be performed according to a network element supporting the same algorithm type, or the grouping may be performed according to accuracy information of the candidate members, for example, the grouping may be performed according to a radio access system of the candidate members, for example, the grouping may be performed according to a signal quality of the candidate members, or the grouping may be performed according to traffic information of the candidate members, or the grouping may be performed according to a time period in which the candidate members can perform federal learning, for example, the grouping may be performed according to the same time period in which the candidate members can perform federal learning, for example, all 10 points to 12 points in the daytime, and so on.
When the first network element sends a response message to the second network element, the identification of the candidate member in the response message is the identification obtained after grouping according to the third information.
In this embodiment, the first network element groups the determined candidate members according to the third information, so that after receiving the identification information of the candidate members sent by the first network element, the second network element further screens the candidate members more meeting the requirements of the second network element according to the grouping information to participate in subsequent federal learning, thereby improving the efficiency of federal learning.
Step 203: the first network element sends a response message to the second network element, the response message including the identification of the candidate member.
In this step, after determining candidate members that can participate in federal learning, the first network element may send the identifiers of the candidate members to the second network element with the identifiers in a response message. The candidate member identification may include a user permanent identifier (Subscriber Permanent Identifier, SUPI) or a network protocol (Internet Protocol, IP) of the candidate member, which may also be a universal public subscription identity (Generic Public Subscription Identifier, GPSI), an international mobile subscriber identity (International Mobile Subscriber Identity, IMSI), an AF-specific UE identity (AF specific UE ID), or a UE IP address.

The area where the candidate member is located may include a location where the candidate member is located, such as longitude and latitude, or a cell.
The time period for the candidate member to perform federal learning is a prediction result analyzed by the first network element according to the willingness information and the capability information of each device.
The signal quality of the candidate member, in the case of a connected WLAN, may be expressed as the mean, variance or RTT of the RSSI.

Optionally, the above response message may further include quantity information, where the quantity information may be understood as the number of members participating in federal learning, i.e. the number of candidate members that needs to be determined by the first network element.
Further, after receiving the response message sent by the first network element, the second network element selects a target member actually participating in federal learning according to the situation of actually performing federal learning training.
For example, the second network element may determine the member to perform federal learning according to the signal quality of the candidate member in the response message, and may select the first 100 members with the best signal quality to perform federal learning. Of course, the manner of determining the target member according to other information in the response message is similar to the manner of determining the target member according to the signal quality, and will not be described herein.
Optionally, if the response message returned by the first network element includes the target number of candidate members under the condition that the request message sent by the second network element to the first network element includes the number information, the second network element may directly use the target number of candidate members as the target members. For example, if the request message includes 50 members requiring federal learning, and the response message returned by the first network element includes 50 candidate members, the second network element may directly select the 50 members as target members.
Further, the second network element connects the target members according to the identification information of the target members after determining the target members so as to perform federal learning.
In this embodiment, the second network element may further screen the target member actually participating in federal learning according to the candidate member returned by the first network element, so that the screened target member is more suitable for participating in federal learning, and efficiency of federal learning is improved.
