Exemplary embodiments will be described in detail herein, with examples shown in the accompanying drawings.

[0042] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0043] First, the relevant technologies involved in the embodiments of this application are introduced:

[0044] Federated Learning (FL):

[0045] As the performance of cameras and sensors on mobile devices continues to improve, more and more devices are able to collect valuable training data, which is essential for training artificial intelligence (AI) or machine learning (ML) models. For many AI / ML tasks, small sample data collected by mobile devices is crucial for training global models.

[0046] In the federated learning architecture diagram shown in Figure 1, the federated learning server completes global model training by aggregating local training results reported by each federated node. Federated nodes can also be called federated terminal devices, or simply terminal devices. In each training iteration, the terminal device can use local training data to train the global model downloaded from the federated learning server, and then report intermediate training results, such as the gradient of the deep neural network (DNN), to the federated learning server via the uplink channel. The federated learning server then aggregates the collected gradients and updates the global model. The federated learning server distributes the updated global model to each terminal device via the downlink channel, and the terminal device performs the next iterative training based on this updated model.

[0047] A group of federated nodes and a server exchange data over the network. Since the federated server must aggregate the training results from all federated nodes before completing global model training, the slowest training result received by the federated server is the terminal device that slows down overall training efficiency. When network resources are limited for federated learning, fewer communication resources can be allocated to terminal devices that produce training results quickly (i.e., those with strong local computing power). This allows these devices to report training results more slowly, while more communication resources can be allocated to terminal devices that produce training results slowly (i.e., those with weak local computing power). This allows these devices to report training results more quickly. This allows training results from all federated nodes to arrive at the federated server simultaneously or nearly simultaneously, even when network resources are limited, effectively improving the overall efficiency of federated learning.

[0048] Network architecture:

[0049] A communication system in related technologies may include at least one of the following: user equipment (UE), radio access network (RAN), core network (CN), and data network (DN). The UE, RAN, and core network can be logically divided into two parts: the user plane and the control plane. The control plane is responsible for mobile network management, while the user plane is responsible for service data transmission.

[0050] One of the key features of such communication systems is a service-oriented architecture, whereby core network elements (i.e., service providers) provide specific services and make them available to other network elements (i.e., consumers) through defined application programming interfaces (APIs). Core network elements are also referred to as core network functions (NFs).

[0051] The core network elements in the related technology include at least one of the following: Access and Mobility Management Function (AMF) is mainly responsible for mobility management in mobile networks, such as user location update, user registration network, user switching, etc.; Session Management Function (SMF) is mainly responsible for session management in mobile networks, such as session establishment, modification, and release; Policy Control Function (PCF) mainly supports providing a unified policy framework to control network behavior, provides policy rules to the control layer network function, and is responsible for obtaining user contract information related to policy decisions; Authentication Server Function (AUSF) is used to perform security authentication of terminal devices; Network Exposure Function (NEF) is mainly used to support the opening of capabilities and events; Network Repository Function (NRF) is used to provide other network elements with storage and selection functions for network function entity information; Unified Data Management (UDM) is used to store user data, such as contract data, authentication / authorization data, etc.; Application Function (AUSF) is used to store user data, such as contract data, authentication / authorization data, etc. The User Plane Function (UPF) is used to provide application layer services, such as application layer data routing, access network capability exposure, interaction with the policy framework to provide policy control, and interaction with the IP Multimedia Core Network Subsystem (IMS). The User Plane Function (UPF) is responsible for forwarding and receiving user data. The Network Slice Selection Function (NSSF) is mainly used for the selection of network slices. The Network Slice Specific Authentication and Authorization Function (NSSAAF) mainly supports the authentication and authorization of network slices. The Service Communication Proxy (SCP) is mainly used for flexible routing, message forwarding, proxy service discovery and other functions.

[0052] In the architectural diagram of the communication system shown in Figure 2, the UE accesses the mobile network. Taking the access network device as a base station as an example, the UE establishes an access stratum (AS) connection with the base station, exchanges AS messages and performs wireless data transmission. The UE establishes a non-access stratum (NAS) connection with the AMF, and exchanges NAS messages. The AMF is responsible for managing the UE's mobility, and the SMF is responsible for managing the UE's session. In addition to managing the UE's mobility, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. The PCF is responsible for formulating policies related to the UE's mobility management, session management, and billing. The UPF is connected to the base station and the external data network and performs data transmission.

[0053] Network Data Analytics Function (NWDAF):

[0054] In related technologies, a new NWDAF network element has been added to the core network, which can collect data from other core network elements, network management systems, etc., and perform big data statistics, analysis or intelligent data analysis to obtain analysis results or predicted data on the network side, thereby assisting each core network element to more effectively control UE access based on data analysis results or predicted data.

[0055] Simply put, the NWDAF network element can collect data from other core network elements and use it for big data analysis. To this end, the relevant technology defines the interface between the NWDAF network element and other NFs, as shown in Figure 3. For example, when any other NF requests an analysis result (identified by an Analytics ID) from the NWDAF network element, it is implemented through the Nnwdaf interface. Similarly, when the NWDAF network element sends an analysis result to any other NF, it is implemented through the Nnf interface. The Analytics ID is the analysis identity (ID) used to identify the content that any other NF requests the NWDAF network element to analyze.

[0056] Table 1 shows some of the analysis results that the NWDAF network element can provide.

[0057] Table 1 Some analysis results that can be provided by NWDAF network elements

[0058] When the application server wants to perform an AI application operation with the UE, such as model delivery and model aggregation in federated learning, or other AI operations such as model segmentation, the application server wants to know in advance the communication performance of the UE that may participate in the AI ​​operation. In other words, the application server expects to obtain the predicted results of the transmission performance of the UE that may participate in the AI ​​operation, such as the transmission time required to complete a model transmission between the UE and the server, the time required for the UE to complete a model transmission, the transmission time required from the UE to the server, etc. The application server can select a suitable UE for the AI ​​operation based on the prediction result. In addition, the prediction result can also be used to support other network elements of the core network to select a suitable UE to perform the AI ​​operation, or to support other network elements of the core network to recommend a suitable UE to the application server to perform the AI ​​operation, or to support other network elements of the core network to recommend a suitable operation time window to the application server to perform the AI ​​operation. Therefore, such prediction is of great significance.

[0059] However, there is no solution for how the core network generates predictions of UE communication performance, such as the prediction of UE transmission completion time.

[0060] Therefore, the present application provides a method for analyzing transmission information, which implements statistics, analysis, and prediction of UE transmission information, such as prediction of UE transmission time, by newly defining the analysis supported by the NWDAF network element.

[0061] Figure 4 shows a schematic diagram of the architecture of a communication system 400 provided in some exemplary embodiments of the present application. As shown in Figure 4, the communication system 400 may include at least one of the following: a terminal device 401, an access network 403, a core network 405, and a data network 407. The terminal device 401, access network 403, and core network 405 can be logically divided into two parts: a user plane and a control plane. The control plane is responsible for mobile network management, and the user plane is responsible for transmitting service data.

[0062] Terminal device 401 is the gateway for mobile users to interact with the network. It provides basic computing and storage capabilities, displays service windows to users, and accepts user input. Terminal device 401 uses certain air interface technologies to establish signal and data connections with access network 403, thereby transmitting control signals and service data to the mobile network. The terminal device 401 can be deployed on land, on water, and in the air, and includes but is not limited to: handheld devices, wearable devices, vehicle-mounted devices, and Internet of Things devices, such as: mobile phones, tablet computers, e-book readers, laptop computers, desktop computers, televisions, game consoles, mobile Internet devices (MID), virtual reality (VR) devices, augmented reality (AR) devices, mixed reality (MR) devices, extended reality (XR) devices, baffle reality (BR) devices, cinematic reality (CR) devices, deceived reality (DR) devices, wearable devices, handles, electronic tags, controllers, wireless terminals in industrial control (Industrial Control), wireless terminals in self-driving (Self Driving), wireless terminals in remote medical (Remote Medical), wireless terminals in smart grid (Smart Grid), wireless terminals in transportation safety (Transportation Safety), and wireless terminals in smart city (Smart City). City), wireless terminals in smart homes, wireless terminals in remote medical surgery, cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), TV set-top boxes (STBs), and customer premises equipment (CPEs).

[0063] Access network 403 is used to implement access-related functions. It can provide network access for authorized users within the cell's coverage area and can transmit user data using transmission tunnels of varying quality based on user level and service requirements. Access network 403 can manage its own resources, utilize them rationally, provide access services to terminal device 401 on demand, and forward control signals and user data between terminal device 401 and core network 405. Access network 403 may include access network equipment, which can be equipment that provides access for terminal device 401 and can include radio access network (RAN) equipment and AN equipment. RAN equipment is primarily wireless network equipment in 3GPP networks, while AN equipment can be access network equipment not defined by 3GPP. In systems using different radio access technologies, the names of devices with base station functions may vary. For example, in 5th Generation Mobile Communication Technology (5G) systems, they are called RAN or Next Generation Node Basestation (gNB); in Long Term Evolution (LTE) systems, they are called evolved NodeBs (eNBs or eNodeBs).

[0064] Core network 405 is responsible for maintaining mobile network subscription data, managing mobile network elements, and providing functions such as session management, mobility management, policy management, and security authentication for terminal device 401. For example, when terminal device 401 is attached, core network 405 provides network access authentication for terminal device 401; when terminal device 401 has a service request, core network 405 allocates network resources for terminal device 401; when terminal device 401 moves, core network 405 updates network resources for terminal device 401; when terminal device 401 is idle, core network 405 provides a fast recovery mechanism for terminal device 401; when terminal device 401 detaches, core network 405 releases network resources for terminal device 401; and when terminal device 401 has service data, core network 405 provides data routing functions for terminal device 401, such as forwarding uplink data to data network 407; or receiving downlink data from data network 407 for terminal device 401 and forwarding it to access network 403, thereby sending the downlink data to terminal device 401. The core network 405 is deployed in a private network or a public network.

[0065] Data network 407 is used to provide business services to users. Data network 407 can be a private network, such as a local area network (LAN); an external network not controlled by the operator, such as the Internet; or a proprietary network jointly deployed by operators, such as the IP Multimedia Core Network Subsystem (IMS). Terminal device 401 can access data network 407 through an established Protocol Data Unit (PDU) session.

[0066] In some embodiments, the access network 403 and / or the core network 405 and / or the data network 407 may be considered as network devices.

[0067] For example, there are two communication scenarios in communication system 400: uplink communication and downlink communication. Uplink communication refers to sending signals in the direction of terminal device 401, access network 403, core network 405, and data network 407; downlink communication refers to sending signals in the direction of data network 407, core network 405, access network 403, and terminal device 401.

[0068] It should be understood that in some embodiments of the present application, "5G" may also be referred to as "5G New Radio (NR)" or "NR", and the terminal device may also be referred to as user equipment (UE), or access terminal, or user unit, or user station, or mobile station, or mobile station, or remote station, or remote terminal, or mobile device, or user terminal, or terminal, or wireless communication device, or user agent, or user device.

[0069] The technical solutions described in some embodiments of the present application may be applicable to 5G systems, LTE systems, and systems evolved from 5G systems and LTE systems, as well as to Beyond Fifth Generation (B5G) systems, 6G systems, and subsequent evolutionary systems. The 5G system may include non-standalone (NSA) and / or standalone (SA) networking.

[0070] Figure 5 shows a detailed architecture based on Figure 4, including all or a portion of the network elements shown in Figure 5. The functions corresponding to the network elements shown in Figure 2 have been previously mentioned and will not be repeated here. The network elements not shown in Figure 2 are as follows: NWDAF, as described above, is primarily used for network data analysis; Operation Administration and Maintenance (OAM), is primarily used for network and service operations, maintenance, and management.

[0071] NWDAF collects data from other NFs, UEs, external application servers (Application Servers) or AFs.

[0072] In the architecture shown in Figure 5, the N1 interface is the reference point between the UE and the AMF; the N2 interface is the reference point between the RAN and the AMF, used for sending NAS messages, etc.; the N3 interface is the reference point between the RAN and the UPF, used for transmitting user plane data, etc.; the N4 interface is the reference point between the SMF and the UPF, used to transmit information such as tunnel identification information of the N3 connection, data cache indication information, and downlink data notification messages; the N6 interface is the reference point between the UPF and the DN, used for transmitting user plane data, etc. The N9 interface is the user plane interface between the UPFs, used to transmit uplink and downlink user data flows between the UPFs. The Nsmf interface is the service-based interface provided by the SMF. Similarly, the service-based interfaces corresponding to other network elements are shown in the figure and will not be repeated here. The NG interface (not shown in the figure) is the interface between the RAN and the core network.

[0073] It should be noted that the interface name between the various network elements in Figures 4 and 5 is only an example. The name of the interface in the specific implementation may be other names, and the embodiments of the present application do not specifically limit this. The names of the various network elements (such as SMF, AF, UPF, etc.) included in Figures 4 and 5 are also only examples and do not constitute any limitation on the functions of the network elements themselves. In the networks in the relevant technology and other future networks, the above-mentioned network elements may also have other names, and the embodiments of the present application do not specifically limit this. For example, in a 6G network, some or all of the above-mentioned network elements may use the terminology in 5G, or may use other names, etc., which are uniformly explained here and will not be repeated below. In addition, it should be understood that the name of the message (or signaling) transmitted between the above-mentioned network elements is also only an example and does not constitute any limitation on the function of the message itself.

[0074] FIG6 is a flow chart showing a method for analyzing transmission information provided by some exemplary embodiments of the present application. The method is illustrated by taking the NWDAF shown in FIG4 as an example. The method includes at least some of the following steps:

[0075] Step 620: Receive an analysis request sent by the first network element;

[0076] The analysis request is used to request analysis of UE transmission information, and / or to request analysis of UE transmission information related to a single transmission, and / or to request analysis of UE transmission information related to transmission of a first amount of data.

[0078] The analysis result includes UE transmission information, and / or UE transmission information related to a single transmission, and / or UE transmission information related to transmission of the first data volume.

[0079] The analysis request is also called a statistical request or a prediction request. The analysis result is also called a statistical result or a prediction result. After receiving such a request from the first network element, the NWDAF will feedback the statistical result / analysis result / prediction result related to the UE transmission information to the first network element.

[0080] UE transmission information can also be understood as UE transmission capability information, or as UE transmission performance information, or as UE communication capability information, or as UE communication performance information.

[0081] In summary, the method provided in this application is that the NWDAF receives the analysis request and sends the analysis result to realize the analysis of the UE transmission information.

[0333] FIG10 is a flow chart showing a method for analyzing transmission information provided by some exemplary embodiments of the present application. The method includes at least some of the following steps:

[0334] Step 901: NF sends an analysis request to NWDAF;

[0335] The NF sends an Nnwdaf_AnalyticsInfo_Request to the NWDAF. The parameters include: the analytics ID (UE transmission completion time); candidate terminal devices (a list of UE IDs); the region of interest (ROI) (cell B); the network slice (NS1); the DNN (local area network 2); and the preferred time window (6:10 PM to 6:20 PM). The analytics ID represents the analysis content, the candidate terminal devices represent the analysis targets, and the region of interest, network slice, DNN, and preferred time window represent analysis filtering information.

[0336] NF is, for example, NEF and / or PCF.

[0337] Step 902: NWDAF receives input parameters sent by OAM and / or AMF and / or AF;

[0338] The NWDAF collects QoS information related to the terminal device corresponding to the UE ID in the analysis request from the OAM, such as the bit rate, transmission rate, packet delay, etc. This information enables the NWDAF to calculate and predict the time required for the UE to transmit a certain amount of data at a certain time in the future (for example, from 18:10 to 18:20).

[0339] NWDAF also collects information about the amount of data required to be transmitted from AF, that is, the amount of data required to transmit a certain service (such as services related to network slice NS1 and / or LAN 2).

[0340] NWDAF also collects the geographical distribution information of UEs from AMF and / or OAM, so as to know which UEs in the terminal devices corresponding to the UE ID are located in the cell B corresponding to the area of ​​interest parameter.

[0341] Step 903: NWDAF determines the analysis result based on the received input parameters;

[0342] Based on the information collected in step 902, NWDAF counts or predicts the transmission completion time of the UE at a certain time in the future (for example, from 18:10 to 18:20). The analysis results generated are described in the previous step 760 and will not be repeated here.

[0343] Step 904: NWDAF sends the analysis result to NF;

[0344] The NWDAF sends Nnwdaf_AnalyticsInfo_Request Response to the NF, and the corresponding analysis identifier is the UE transmission completion time.

[0345] Steps 901 to 904 can be considered as steps for a one-time report (One-Time Report) of analysis results.

[0346] Step 905: NF sends a persistence analysis request to NWDAF;

[0347] The NF sends Nnwdaf_AnalyticsSubscription_Subscribe to the NWDAF. In addition to the parameters described in step 901, the parameters included also include an indication of continuous reporting. For example, the frequency of NWDAF sending analysis results is expected to be continuous reporting, that is, if the threshold value of a certain parameter is reached, the NWDAF needs to notify the NF or send updated analysis results to the NF.

[0348] Step 906: The NWDAF receives input parameters sent by the OAM and / or AMF and / or AF and / or UPF.

[0349] The NWDAF collects QoS information related to the terminal device corresponding to the UE ID in the analysis request from the OAM, such as the bit rate, transmission rate, packet delay, etc. This information enables the NWDAF to calculate and predict the time required for the UE to transmit a certain amount of data at a certain time in the future (for example, from 18:10 to 18:20).

[0350] NWDAF also collects information about the amount of data required to be transmitted from AF, that is, the amount of data required to transmit a certain service (such as services related to network slice NS1 and / or LAN 2).

[0351] NWDAF also collects the geographical distribution information of UEs from AMF and / or OAM, so as to know which UEs in the terminal devices corresponding to the UE ID are located in the cell B corresponding to the area of ​​interest parameter.

[0352] NWDAF also collects information such as the UE's real-time bit rate and packet delay from the UPF, thereby analyzing the UE's transmission completion time in real time or predicting the UE's transmission time completion performance in real time.

[0353] Step 907: NWDAF determines the analysis result based on the received input parameters;

[0354] Step 908: NWDAF sends the analysis result to NF;

[0355] NWDAF sends Nnwdaf_AnalyticsSubscription_Notify to NF, and the corresponding analysis identifier is the UE transmission completion time.

[0356] Step 909a: If the NWDAF sets the first threshold to the OAM in step 906, when the OAM detects that the UE's QoS information or geographical distribution information reaches the first threshold, the OAM notifies the NWDA of the updated information.

[0357] Step 909b: If the NWDAF sets the second threshold to the AMF in step 906, when the AMF detects that the UE enters or leaves the area of ​​interest of the NF (such as cell B), the AMF notifies the NWDAF of the updated information.

[0358] Step 909c: If the NWDAF sets the third threshold to the AF in step 906, then when the AF detects that the amount of transmitted data reaches the third threshold or changes, the AF notifies the NWDAF of the updated information.

[0359] Step 909d: If in step 906, NWDAF sets the fourth threshold to UPF, then when UPF detects that the real-time bit rate or packet delay of the UE reaches the fourth threshold, or the real-time bit rate or packet delay of the UE changes, UPF notifies NWDAF of the updated information, that is, obtains data from UPF.

[0360] Step 910: The NWDAF determines an updated analysis result based on the received updated information;
