[0101] The network device may be a device in a wireless network, and in this application, may also be referred to as an operator device. For example, the network device may be a device deployed in a wireless network to provide wireless communication functions for terminal devices. For example, the network device may be a radio access network (RAN) node that connects the terminal device to the wireless network. Among them, the RAN may be connected to a core network (for example, a core network of long term evolution (LTE), a core network of 5G, etc.).

[0102] The network device in the embodiment of the present application may be an access network device, including but not limited to: various base stations, such as the next generation Node B (gNodeB, gNB), evolved Node B (evolved Node B, eNB) or base station equipment in the future evolved communication system, or a server, a wearable device, a vehicle-mounted device, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., or one or a group of antenna panels (including multiple antenna panels) of a base station, or a network node constituting a base station, such as a baseband unit (BBU), or a distributed unit (DU), etc. Among them, the base station may be a macro base station, a micro base station, a micro-micro base station, a small station, a relay station or a balloon station, etc.

[0103] The network device in the embodiment of the present application may also be a core network device, including but not limited to: an access and mobility management function (AMF) network element, a session management function (SMF) network element, a user plane function (UPF) network element, a policy control function (PCF) network element, or a unified data management function (UDM) network element, etc.

[0104] Application layer network elements refer to network devices in computer networks that are responsible for processing application layer protocols, including but not limited to: data collection application function (DCAF) network elements, provisioning application function (PAF) network elements, event consumer application function (ECAF) network elements, etc.

[0105] It can be understood that all or part of the functions of the network device or terminal device in the present application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0106] Figure 2 Schematic diagram of the architecture of an access network device provided in an embodiment of the present application. Figure 2 As shown, the network device involved in the embodiment of the present application can be a centralized unit (CU) and a distributed unit (DU) separation architecture. CU and DU can be understood as the division of network devices from the perspective of logical functions. CU and DU can be physically separated or deployed together. Multiple DUs can share one CU. One DU can also be connected to multiple CUs ( Figure 2 CU and DU may be connected via an interface, such as an F1 interface. CU and DU may be divided according to the protocol layer of the wireless network. One possible division method is that CU is used to perform the functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and the packet data convergence protocol (PDCP) layer, and DU is used to perform the functions of the radio link control (RLC) layer, the media access control (MAC) layer, the physical layer, etc.

[0107] It is understandable that the division of the processing functions of the CU and DU according to the protocol layer is only an example, and the CU and DU may also be divided in other ways. For example, the CU or DU may be divided into functions of more protocol layers than the above division method. For example, the CU or DU may also be divided into part of the processing functions of the protocol layer of the above division method.

[0108] In one design, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU.

[0109] In another design, the functions of CU or DU can be divided according to service type or other system requirements, for example, by latency, where functions whose processing time meets the latency requirement are implemented in DU, and functions that do not meet the latency requirement are implemented in CU.

[0110] In another design, the CU may also have one or more functions of the core network. One or more CUs may be centrally set or separately set. For example, the CU may be set on the network side for centralized management. The DU may have multiple radio frequency functions or the radio frequency functions may be remotely set.

[0111] The functions of CU can be implemented by one entity or by different entities. For example, the functions of CU can be further divided, for example, the control plane (CP) and the user plane (UP) are separated, that is, the control plane (CU-CP) of CU and the user plane (CU-UP) of CU. The control plane CU-CP of CU also includes a further divided architecture, that is, the CU-CP is further divided into CU-CP1 and CU-CP2. Among them, CU-CP1 includes various radio resource management functions, and CU-CP2 only includes RRC functions and PDCP-C functions (that is, the basic functions of control plane signaling at the PDCP layer).

[0112] In different systems, CU (including CU-CP or CU-UP) or DU may have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (O-RAN) system, CU may also be referred to as O-CU (open CU), DU may also be referred to as O-DU, CU-CP may also be referred to as O-CU-CP, and CU-UP may also be referred to as O-CU-UP. This application does not limit this.

[0113] The AI ​​module is a module with machine learning computing capabilities. Figure 2As shown, in a wireless communication system, the AI ​​module can be located in operations, administration and maintenance (OAM), in a gNB (for example, if the gNB is a separated architecture, it can be located in the CU / DU), in a terminal device, or as a separate network element entity RAN Intelligent Control Module (RAN Intelligent Controller, RIC). The main function of the AI ​​module in the wireless communication system is to perform a series of AI calculations such as model establishment, training approximation, and reinforcement learning based on input data (in a wireless communication system, input data generally refers to network operation data provided by access network equipment or monitored by OAM, such as network load, channel quality, etc., or user plane data transmission provided by the core network). The trained model provided by the AI ​​module has the function of predicting changes in the RAN side network, and can be used for load prediction, terminal device path prediction, CSI prediction, optimal beam prediction, positioning prediction, etc. In addition, the AI ​​module can also perform policy reasoning from the perspectives of network energy saving and mobility optimization based on the prediction results of the trained model on the RAN network performance, so as to obtain reasonable and efficient energy saving strategies, mobility optimization strategies, etc. When the AI ​​model is located in the CU and the CP and UP of the CU are separated, the CP can be responsible for receiving the AI ​​model and the subsequent AI reasoning and policy generation functions. When the CU-CP is further divided into CU-CP1 and CU-CP2, CU-CP1 can be responsible for receiving the AI ​​model and the subsequent AI model reasoning functions, and generating specific interactive signaling, which will be sent by CU-CP2. When the AI ​​module is located in OAM, its communication with the gNB on the RAN side can reuse the current northbound interface. When the AI ​​module is located in the gNB or CU, the current F1, Xn, Uu and other interfaces can be reused; when the AI ​​module becomes an independent network entity, it is necessary to re-establish the communication link to the OAM and RAN side, such as based on a wired link or a wireless link.

[0114] Figure 3 Schematic diagram of an AI application framework provided in an embodiment of the present application. Figure 3 As shown, the AI ​​application framework includes a data acquisition module, a model training module, a model reasoning module and an execution entity (Actor).

[0115] Among them, the model training module and the model reasoning module are examples of AI modules. For example, Figure 1 The network devices and terminal devices shown in the figure are Figure 2The CU, DU or other management entities of the gNB shown can input data into the data acquisition module, and the data acquisition module can be used as a database for AI model training and data analysis and reasoning. The model training module analyzes the training data output by the data acquisition module, and gives an available AI model, and deploys the obtained AI model to the model reasoning module. Based on the reasoning data output by the data acquisition module, the model reasoning module gives a reasonable prediction of the network operation based on the AI ​​model (trained by the model training module), and feeds back the performance data of the AI ​​model to the model training module. The subsequent model training module continues to train the model according to the feedback performance data, and informs the model reasoning module of the updated AI model; or, the model reasoning module guides the network to make policy adjustments based on the reasoning data and AI model output by the data acquisition module. The relevant policy adjustments are uniformly planned by the execution entity and sent to multiple network entities for operation. At the same time, the specific performance of the network after the application of the relevant policies will be fed back to the data acquisition module for storage.

[0116] Figure 4 Schematic diagram of another AI application framework provided in the embodiment of the present application. Figure 4 As shown, the framework includes a data acquisition module, a model training module, a model management module, a model reasoning module and a model storage module.

[0117] Among them, the model management module interacts with and manages the remaining modules, and the model storage module is used to store and manage AI models.

[0118] Figure 5 It is a schematic flowchart of an AI model lifecycle management (LCM) provided in an embodiment of the present application.

[0119] For different use cases, there may be different LCM overall signaling processes. Figure 5 The process shown is only an example, and this application does not limit the specific LCM process.

[0120] The 3rd Generation Partnership Project (3GPP) has introduced multiple AI application scenarios on the RAN side. The applications of AI on the RAN side include but are not limited to the following application scenarios: energy saving, load balancing, mobility optimization, channel state information-reference signal (CSI-RS) feedback enhancement, beam management enhancement (BME), and positioning enhancement. These application scenarios can also be called AI use cases.

[0121] For example, AI can be used for CSI feedback enhancement. CSI is the channel attribute of the communication link. The UE reports the downlink channel quality information to the gNB so that the base station can select a more appropriate modulation and coding scheme (MCS) for the UE. According to the latest progress of the RAN1 meeting, two sub-use cases based on AI, CSI compression and CSI prediction (low priority), were adopted. CSI compression is based on a bilateral model (there is an encoder (and quantizer) on the UE side for compressing CSI, and a decoder (and dequantizer) on the gNB side for decompression; AI-based codecs can be implemented through AI models such as Convolutional Neural Network (CNN) and AI models (Transformer) that use attention mechanisms to increase the speed of model training).

[0122] For example, AI can also be used for beam management (BM), which is mainly used to find the strongest transmit / receive beam pair. The goal of AI / ML-based sparse beam prediction is to improve the accuracy of optimal beam prediction. During the training phase, the network scans all possible beams, and then the network needs to tell the UE the transmit beam pattern. When the model training is completed, the network only needs to scan a small number of beams, and then the UE feeds back the inferred top-K (such as the K beams with the best receiving power) narrow beams to the network.

[0123] Exemplarily, AI can also be used for positioning accuracy enhancements. LOS / NLOS indication reporting is already supported in R17, with the aim of improving positioning accuracy. For AI / ML-based LOS / NLOS recognition, it can improve positioning accuracy with a smaller number of transmission reception point (TRP) antennas. For indoor scenarios (heavy NLOS scenarios), there may not be a sufficient number of line-of-sight paths, and traditional means cannot work well. Therefore, AI-based positioning can improve positioning accuracy in indoor scenarios.

[0124] The input of the AI ​​model in the above AI application scenarios is all access layer data. For example, the input of the model in the CSI compression scenario is the CSI-RS measurement result, which involves access layer CSI reporting. How to collect the UE's AS data and report it to the application layer is an urgent problem to be solved.

[0125] The present application provides a variety of AS data collection methods, which can collect the AS data of the UE when the AS layer and APP layer of the UE collect data independently.

[0126] It should be understood that the description of the specific scenarios in the embodiments of the present application is only an example. In addition to being applicable to the application scenarios described above, the methods provided in the embodiments of the present application are also applicable to application scenarios with similar problems.

[0127] In the description of the embodiments of the present application, unless otherwise specified, "multiple" or "multiple" means two or more. In addition, "at least one" can be replaced by "one or more".

[0128] The ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the size, content, order, timing, priority or importance of multiple objects. For example, the first indication information and the second indication information can be the same information or different information, and such a name does not indicate the difference in the content, size, application scenario, sender / receiver, priority or importance of the two messages. In addition, the numbering of the steps in the various embodiments introduced in the present application is only for distinguishing different steps, and is not used to limit the order of the steps.

[0129] In the present application, the terms "comprises" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0130] The technical solution provided in the embodiment of the present application can be applied to wireless communication between communication devices. Wireless communication between communication devices may include: wireless communication between network devices and terminals, wireless communication between network devices and network devices, and wireless communication between terminals. In the embodiment of the present application, the term "wireless communication" may also be referred to as "communication", and the term "communication" may also be described as "data transmission", "information transmission" or "transmission".

[0131] It should be understood that the names of all nodes and messages in this application are merely names set for the convenience of description in this application. The names in the actual network may be different. This application should not be understood to limit the names of various nodes and messages. On the contrary, any name that has the same or similar function as the node or message used in this application is regarded as the method of this application or an equivalent replacement, and is within the scope of protection of this application, and will not be repeated below.

[0132] The various methods provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0133] It should be understood that the step numbers in the embodiments of the present application are only used for illustration and do not limit the order in which the steps occur.

[0134] Figure 6 A data collection method 600 provided by the present application is shown, through which the AS data of the UE is collected. Figure 6 The method includes at least part of the following contents.

[0135] S610, the PAF sends measurement and reporting configuration information of access layer data to the DCAF.

[0136] S620, the event user application function network element (ECAF) sends a subscription request message (ie, an example of the first request message) to the DCAF.

[0137] S630, DCAF sends first information to the network device, where the first information is used to request a first access layer data set of the UE.

[0138] S640: The network device sends third information to the DCAF, where the third information is used to indicate which data in the first access layer data set is accepted by the network device and / or which data is not accepted by the network device.

[0139] S650, DCAF sends third information to the event user application function network element.

[0140] S660, the network device sends first indication information to the AS layer of the UE, where the first indication information is used to instruct the AS layer of the UE to measure a second access layer data set.

[0141] S670: The AS layer of the UE performs measurement.

[0142] S680, the AS layer of the UE sends second information to the network device, where the second information is used to indicate a second access layer data set.

[0143] S690: The network device sends second information to the DCAF.

[0144] S691, DCAF stores the second access layer data set.

[0145] S692, DCAF sends the second information to the event user application function network element.

[0146] Through the above scheme, ECAF can send the AS layer data collection requirements required for its training model as subscription information to DCAF, and then send it to the network device through DCAF. The AS data is collected and forwarded to DCAF through the network device. Finally, ECAF obtains the subscribed AS layer data collection results from DCAF, thus completing the process of ECAF collecting AS layer measurement results.

[0147] The following is a detailed introduction to S610 to S692.

[0148] In S610, the PAF sends measurement and reporting configuration information of access layer data (ie, an example of the fourth information) to the DCAF.

[0149] It should be understood that the PAF can send measurement and reporting configuration information of UE-related data to the DCAF, including measurement and reporting configuration information of the UE's access layer data.

[0150] In one implementation, the PAF may indicate to the DCAF (for example, by sending indication information, or carrying the indication information in the measurement and reporting configuration information of the UE-related data) which of the UE-related data is access layer-related data.

[0151] It should be understood that the measurement and reporting configuration information of the access layer data includes the measurement and reporting configuration information of the first access layer data set.

[0152] Specifically, the measurement and reporting configuration information may include: what data needs to be collected, the configuration of data collection (such as the sampling frequency of collection, geographical restrictions, etc.), the reporting frequency and format of the collected data, how DCAF processes this data and how it sends it to the corresponding subscribers (or event users).

[0153] In one implementation, the collected data information may include one or more of the following: artificial intelligence AI function information indicating access layer data corresponding to the access layer data (the AI ​​function may indicate one or more functions including but not limited to CSI compression, CSI prediction, BM, and positioning), target frequency information measured by the UE, reference signal type information measured by the UE (for example, indicating SSB and / or CSI), channel quality type information measured by the UE (for example, RSRP / RSRQ / SINR, etc.), indication information collected and reported via the UE's physical layer L1 and / or network layer L3, scenario information requiring collection of access layer data (for example, a specific region, cell, cell configuration, etc., and information on the maximum number of beams reported (for example, indicating measurement results of 4 / 6 / several Beams).

[0154] In S620, ECAF sends a subscription request message to DCAF.

[0155] It should be understood that the ECAF may refer to one or more ECAFs. ECAF sends subscription request information to DCAF, which can also be understood as one or more ECAFs sending subscription request information to DCAF respectively.

[0156] It should be understood that the subscription request information is used to request a first access layer data set, wherein the first access layer data set includes at least one sub-access layer data.

[0157] In one implementation, the subscription request information includes the target UE information corresponding to the measurement (such as UE ID, UE IP address, or UE cluster ID, and any identification information that can point to a specific UE), measurement event ID (which can be one or a group of event IDs), and measurement result reporting configuration (event / periodic reporting, reporting duration, maximum number of reports, etc.).

[0158] It should be understood that in this subscription request information, ECAF may further send subscription information related to the model to DCAF to request the measurement results required for the ECAF local training model. For example, ECAF may indicate that there is a model to be trained locally, and include the functional information corresponding to the training model (e.g., measurement information corresponding to the CSI compression function).

[0159] In S630, the DCAF sends first information to the network device, where the first information is used to request a first access layer data set of the UE, or in other words, the first information is used to indicate a measurement requirement for the first access layer data set.

[0160] It should be understood that the first access layer data set is a set of access layer data requested by at least one ECAF through subscription request information. The first access layer data set includes at least one access layer data group, wherein each access layer data group includes at least one sub-access layer data.

[0161] In one implementation, the DCAF obtains the measurement and reporting configuration information of the UE-related data according to step S610, identifies the measurement and reporting configuration related to the AS data collection, and sends it to the network device.

[0162] In another implementation, the DCAF may determine which of the UE-related data is access layer-related data through the indication information sent by the PAF, and send its measurement and reporting configuration to the network device.

[0163] This solution does not restrict the sending format of the first information.

[0164] In one implementation, the first information includes measurement and reporting configuration information of the first access layer data set.

[0165] In one implementation, the first information needs to include one or more of the following information: artificial intelligence AI function information indicating the access layer data corresponding to the access layer data (the AI ​​function may indicate one or more functions including but not limited to CSI compression, CSI prediction, BM, positioning), target frequency information measured by the UE, reference signal type information measured by the UE (for example, indicating SSB and / or CSI), channel quality type information measured by the UE (for example, RSRP / RSRQ / SINR, etc.), indication information collected and reported via the UE's physical layer L1 and / or network layer L3, scenario information where access layer data needs to be collected (for example, a specific region, cell, cell configuration, etc., and information on the maximum number of beams reported (for example, indicating measurement results of 4 / 6 / several Beams).

[0166] In addition, as shown in Table 1, in the first information, each event ID having AS data collection requirements may be indicated separately, or an event ID group having all or part of the same AS data collection requirements may be indicated.

[0167] Table 1

[0168]

[0169] In one implementation, the first information also includes first identification ID information and / or second ID information. The first ID information is used to indicate the ID of the event or event group corresponding to each access layer data group. The second ID information can also be understood as the source ECAF indication information of the data collection requirement, which is used to indicate the ID of the ECAF corresponding to each access layer data group.

[0170] In addition, the first information may further include corresponding AS data for ECAF to perform model training, and one or more functional information corresponding to the training model.

[0171] In S640, the network device sends third information to the DCAF, where the third information is used to indicate which data in the first access layer data set is accepted by the network device and which data is not accepted by the network device.

[0172] The network device feeds back to the DCAF (ie sends the third information) according to the AS measurement requirement received in step S630.

[0173] In one implementation, the third information is also used to indicate the ID of the event or event group accepted or not accepted by the network device, or the third information is used to indicate the ID of the sub-access layer data accepted or not accepted by the network device.

[0174] In one implementation, the third information is also used to indicate the reason why the network device accepts or does not accept specific access layer data (for example, based on considerations such as authority and insufficient measurement resources).

[0175] It should be understood that, through the third information, DCAF can learn that what the network device receives is the second access layer data set.

[0176] In S650, the DCAF sends the third information to the ECAF.

[0177] Based on the feedback result received in S640 , the DCAF may further feedback the acceptance result of the network device to the AS data measurement request to the ECAF that has subscribed to the corresponding event (group).

[0178] In S660, the network device sends first indication information to the AS layer of the UE, where the first indication information is used to instruct the AS layer of the UE to measure the second access layer data set.

[0179] It should be understood that the second access layer data set includes all or part of the access layer data in the first access layer data set, or in other words, the second access layer data set is a subset of the first access layer data set.

[0180] In one implementation, the second access layer data set includes access layer data in the first access layer data set that is accepted by the network device.

[0181] In one implementation, the first indication information includes measurement and reporting configuration information of the second access layer data set.

[0182] In one implementation, through the first indication information, the network device can indicate to the UE which measurement requirements in the second access layer data set are from the AS data collection request of the DCAF.

[0183] In one implementation, the first indication information also includes at least one of the following information: first ID information, second ID information, and function indication information of AI model training. That is, through the first indication information, the network device can further indicate the ECAF, event ID, and model training functions corresponding to these AS data collection requests.

[0184] In S670, the AS layer of the UE performs measurement. In S680, the AS layer of the UE sends second information to the network device, where the second information is used to indicate the second access layer data set. In S690, the network device sends the second information to the DCAF.

[0185] It should be understood that the AS layer of the UE can measure the access layer data according to the measurement requirements indicated by the first indication information, and send the measurement results to the network device through the second information, and the network device then sends the measurement results to the DCAF. This application does not limit the reporting method of the second information, which can be reported in a one-to-one correspondence between events and AS measurement results, or all AS measurement results can be directly reported, and the DCAF will make the relationship correspondence.

[0186] In S691, the DCAF stores the second access layer data set.

[0187] After obtaining the measurement results and the correspondence between the measurement results and the event IDs, the DCAF stores the measurement results and the correspondence locally in the DCAF.

[0188] In S692, DCAF sends the second information to ECAF.

[0189] According to the subscription request information received by the DCAF in S610, the DCAF selects the measurement result corresponding to the corresponding event ID (ie, the second access layer data set), and sends it to the corresponding ECAF.

[0190] Figure 7 A communication method 700 provided by the present application is shown, through which the AS data of the UE is collected. Figure 7 The method includes at least part of the following contents.

[0191] S710, the PAF sends measurement and reporting configuration information of access layer data to the DCAF.

[0192] S720, ECAF (Event Consumer) sends a subscription request message to DCAF.

[0193] S730, DCAF sends first information to the non-AS layer of the UE, where the first information is used to request a first access layer data set of the UE, and the first information includes measurement and reporting configuration information of the first access layer data set.

[0194] S740, the AS layer of the UE performs measurement.

[0195] S750, the non-AS layer of the UE sends first request information to the AS layer of the UE, where the first request information is used to request a first access layer data set.

[0196] S760, the AS layer of the UE sends second information to the non-AS layer of the UE, where the second information is used to indicate a second access layer data set.

[0197] S770, the non-AS layer of the UE sends second information to the DCAF.

[0198] S780, DCAF stores the second access layer data set.

[0199] S790, DCAF sends the second information to ECAF.

[0200] Through the above scheme, ECAF can send the AS layer data collection requirements required for its training model as subscription information to DCAF, and send it to the non-AS layer of the UE via DCAF, collect AS measurement data from the UE's AS layer through the UE's non-AS layer, and forward it to DCAF. Finally, ECAF obtains the subscribed AS layer data collection results from DCAF, thereby completing the process of ECAF collecting AS layer measurement results.

[0201] The following is a detailed introduction to S710 to S790.

[0202] Steps S710 to S720 may refer to steps S610 and S620 .

[0203] In S730, the DCAF sends first information to the non-AS layer of the UE, where the first information is used to request a first access layer data set of the UE, or in other words, the first information is used to indicate a measurement requirement for the first access layer data set.

[0204] In an embodiment of the present application, the non-AS layer of the UE includes but is not limited to the application APP layer of the UE, the direct data collection client (Direct Data Collection Client, DDCC) of the UE, and the indirect data collection client (Indirect Data Collection Client, IDCC) of the UE.

[0205] It should be understood that the first access layer data set is a set of access layer data requested by at least one ECAF through subscription request information. The first access layer data set includes at least one access layer data group, wherein each access layer data group includes at least one sub-access layer data.

[0206] The DCAF identifies the measurement and reporting configurations related to AS data collection according to the measurement and reporting configurations acquired in step S710, and sends the measurement and reporting configurations to the network device. This solution does not limit the sending format of the first information.

[0207] In one implementation, the first information includes measurement and reporting configuration information of the first access layer data set.

[0208] In one implementation, the first information needs to include one or more of the following information: artificial intelligence AI function information indicating the access layer data corresponding to the access layer data (the AI ​​function may indicate one or more functions including but not limited to CSI compression, CSI prediction, BM, positioning), target frequency information measured by the UE, reference signal type information measured by the UE (for example, indicating SSB and / or CSI), channel quality type information measured by the UE (for example, RSRP / RSRQ / SINR, etc.), indication information collected and reported via the UE's physical layer L1 and / or network layer L3, scenario information where access layer data needs to be collected (for example, a specific region, cell, cell configuration, etc., and information on the maximum number of beams reported (for example, indicating measurement results of 4 / 6 / several Beams).

[0209] In addition, similar to Table 1, in the first information, each event (event) ID having AS data collection requirements may be indicated separately, or the event ID group having all or part of the same AS data collection requirements may be indicated.

[0210] In one implementation, the first information also includes first identification ID information and / or second ID information. The first ID information is used to indicate the ID of the event or event group corresponding to each access layer data group. The second ID information can also be understood as the source ECAF indication information of the data collection requirement, which is used to indicate the ID of the ECAF corresponding to each access layer data group.

[0211] In addition, the first information may further include corresponding AS data for ECAF to perform model training, and one or more functional information corresponding to the training model.

[0212] In S740 , the AS layer of the UE performs measurement.

[0213] In this step, the AS layer of the UE performs measurements according to the configuration obtained from the network side. It should be noted that the measurements performed by the UE here have no strict order relationship with the remaining steps, that is, the measurements performed by the UE are performed independently and are not affected by the data collection requests received by the UE non-AS layer.

[0214] In S750, the non-AS layer of the UE sends first request information to the AS layer of the UE, where the first request information is used to request a first access layer data set.

[0215] In one implementation, the first request information includes measurement and reporting configuration information of the second access layer data set.

[0216] In one implementation, the first request information also includes at least one of the following information: first ID information, second ID information, and function indication information of AI model training. That is, through the first request information, the network device can further indicate the ECAF, event ID, and model training functions corresponding to these AS data collection requests.

[0217] In S760, the AS layer of the UE sends second information to the non-AS layer of the UE, where the second information is used to indicate a second access layer data set.

[0218] According to the AS data collection requirement received through the first request information in step S750, the AS layer of the UE can select the corresponding AS measurement result to be sent directly to the non-AS layer, or can further judge and filter the corresponding AS measurement result and send it to the non-AS layer. In other words, the AS layer of the UE can determine that part of the access layer data in the first access layer data set is the second access layer data set, and send it to the non-AS layer of the UE through the second information.

[0219] In one implementation, if the AS layer cannot send the corresponding measurement result to the non-AS layer as required, the AS layer may send a cause indication information to the non-AS layer, such as no corresponding measurement result (the AS layer of the UE is not configured with the corresponding measurement result or the corresponding measurement result has been deleted), or the AS layer does not agree to send the corresponding measurement result to the non-AS layer based on considerations such as authority. The granularity of the cause indication information may be indicated by each measurement result that is not fed back, or may be indicated by a model training function, Event ID, or Event Consumer ID, such as the UE does not feed back the corresponding AS measurement result to the CSI compression function, Event xx, or Event Consumer yy.

[0220] It should be understood that the AS layer of the UE may separately feed back the AS measurement result, or separately feed back the reason indication information of not sending the AS measurement result, or feed back both the AS measurement result that can be provided and the reason indication information of the AS measurement result that cannot be sent.

[0221] In S770, the non-AS layer of the UE sends the second information to the DCAF.

[0222] Specifically, the UE can complete the sending of the second information from the non-AS layer to the DCAF in any of the following ways.

[0223] Method 1

[0224] In step S760, the AS layer of the UE sends the second information to the APP layer in the non-AS layer of the UE, and the APP layer sends the second information to the DDCC.

[0225] In step S770, the DDCC sends the second information to the DCAF.

[0226] Method 2

[0227] In step S760, the AS layer of the UE sends the second information to the APP layer in the non-AS layer of the UE, and the APP layer sends the second information to the indirect data collection client IDCC.

[0228] In step S770, the IDCC sends the second information to the DCAF.

[0229] Method 3

[0230] In step S760, the AS layer of the UE sends the second information to the DDCC in the non-AS layer of the UE.

[0231] In step S770, the DDCC sends the second information to the DCAF.

[0232] Method 4

[0233] In step S760, the AS layer of the UE sends the second information to the IDCC in the non-AS layer of the UE.

[0234] In step S770, the IDCC sends the second information to the DCAF.

[0235] S780 to S790 may refer to steps S691 to S692.

[0236] Figure 8 A data collection method 800 provided by the present application is shown, through which the AS data of the UE is collected. Figure 8 The method includes at least part of the following contents.

[0237] S810, PAF sends measurement and reporting configuration information of access layer data to DCAF.

[0238] S820, ECAF (Event Consumer) sends a subscription request message to DCAF.

[0239] S830, DCAF sends first information to the network device, where the first information is used to request a first access layer data set of the UE.

[0240] S840, the network device sends second indication information to the AS layer of the UE, where the second indication information is used to indicate the measurement and reporting configuration of the first access layer data set.

[0241] S850, the network device sends third information to the DCAF, where the third information is used to indicate which data in the first access layer data set is accepted by the network device and which data is not accepted by the network device.

[0242] S860, DCAF sends a second request message to the non-AS layer of the UE, where the second request message is used to request a third access layer data set of the UE, where the third access layer data set is data accepted by the network device.

[0243] S870, the non-AS layer of the UE sends second request information to the AS layer of the UE.

[0244] S880: The AS layer of the UE performs measurement.

[0245] S890, the AS layer of the UE sends second information to the non-AS layer of the UE, where the second information is used to indicate a second access layer data set.

[0246] S891, the non-AS layer of the UE sends second information to the DCAF.

[0247] S892, DCAF stores the second access layer data set.

[0248] S893, DCAF sends the second information to ECAF.

[0249] Through the above solution, Event Consumer can send the AS layer data collection requirements required for its training model as subscription information to DCAF, and then send it to the operator equipment through DCAF, and then the operator equipment sends it to the AS layer of the UE and additionally instructs the UE AS layer to retain the corresponding measurement results after reporting them, thereby expanding the amount of AS measurement results that can be obtained by the non-AS layer of the UE.

[0250] The following is a detailed introduction to S810 to S893.

[0251] Steps S810 to S830 may refer to steps S610 to S630 .

[0252] In S840, the network device sends second indication information to the AS layer of the UE, where the second indication information is used to indicate the measurement and reporting configuration of the first access layer data set.

[0253] Optionally, since the network device only receives part of the data in the first access layer data set (ie, the third access layer data set), the network device may also only send the measurement and reporting configuration of the third access layer data set to the AS layer of the UE.

[0254] The network device may send additional AS measurement configuration to the AS layer of the UE via the second indication information to meet the AS data collection requirements obtained from the DCAF in step S830.

[0255] On the other hand, under the prior art, after reporting the measurement result, the AS layer of the UE will delete the corresponding measurement result from the local storage of the UE. In order to enable the non-AS layer of the UE to obtain sufficient data collection results, the network device may choose to further indicate in the second indication information which measurement items the UE needs to retain locally even after reporting, so that these measurement results can be subsequently delivered to the non-AS layer of the UE.

[0256] In addition, the network device may also instruct the UE to locally retain relevant configurations of the measurement results in the second indication information.

[0257] For example, the network device may instruct the UE on the length of time to retain certain measurement results.

[0258] For another example, the network device may instruct the UE to retain measurement results of certain measurement items in one or more time periods.

[0259] For another example, the network device may instruct the UE to retain measurement results under a specific configuration, such as measurement results under a specific target frequency point, a specific reference signal type, a specific channel quality type, etc. measured by the UE.

[0260] Step S850 may refer to step S640. It should be understood that, through the third information, the DCAF may learn that the network device receives the third access layer data set, and the third access layer data set includes all or part of the data in the first access layer data set.

[0261] In S860, the DCAF sends a second request message to the non-AS layer of the UE, where the second request message is used to request a third access layer data set of the UE, where the third access layer data set is data accepted by the network device.

[0262] In one implementation, the second request information includes measurement and reporting configuration information of the third access layer data set.

[0263] In one implementation, the second request information also includes at least one of the following information: first ID information, second ID information, and function indication information of AI model training. That is, through the second request information, the network device can further indicate the ECAF, event ID, and model training functions corresponding to these AS data collection requests.

[0265] Step S880 may refer to step S740.
