[0120] In order to better understand the embodiments of the present application, the system architecture involved in the embodiments of the present application is first introduced below:

[0121] The embodiments of the present application will present various aspects, embodiments or features around a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all devices, components, modules, etc. discussed in conjunction with the figures. In addition, combinations of these schemes may also be used.

[0122] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as wireless fidelity (Wi-Fi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, 4th generation (4G) mobile communication systems, such as long term evolution (LTE) systems, worldwide interoperability for microwave access (WiMAX) communication systems, 5th generation (5G) mobile communication systems, such as new radio (NR) systems, and future communication systems, such as 6th generation (6G) mobile communication systems, etc.

[0123] The following is a description of the related technologies involved in the embodiments of the present application.

[0124] 1. EVEX data collection architecture

[0125] The EVEX data collection architecture is an architecture for collecting UE application (APP) layer data or non-access layer data, such as some media stream data and its quality of experience (QoE) indicators. Figure 1 As shown, the EVEX data collection architecture mainly includes UE, DCAF and application service provider (ASP), wherein the UE includes a DDCC module and an application layer module, the DDCC module communicates with the application layer module through the R7 interface, and the DDCC module communicates with the DCAF through the R2 interface.

[0126] ASP includes a provisioning application function (PAF) module, an IDCC module and an event consumer AF (ECAF) module. The PAF module communicates with the DCAF through the R1 interface, the IDCC module communicates with the DCAF through the R3 interface, and the ECAF module communicates with the DCAF through the R6 interface.

[0127] The PAF module sends data collection / processing and event exposure configuration to the DCAF through the R1 interface. The DACF can send data collection and reporting configuration to the corresponding entity. The corresponding entity reports the collected data according to the configuration, such as sending data collection and reporting configuration to the DDCC module through the R2 interface, and then configuring the UE's application layer module to report the collected application layer data. The application layer data collected by the UE's application layer module can be sent to the DCAF in a direct manner (such as through R7-R2), or can be sent to the DCAF in an indirect manner (such as through R8-R3). The DCAF processes the collected data according to the event identification (ID) requirements, and exposes the collected data to subscribers according to the event ID, such as the ASP or the network data analytics function (NWDAF). The DCAF indicates to the DCAF the event ID corresponding to the data to be collected, and the DCAF sends the corresponding collected data to the ASP or NWDAF according to the event ID, wherein the NWDAF and the DCAF communicate through the R5 interface.

[0128] 2. Artificial intelligence (AI)

[0129] AI can be applied to NR to improve network performance and user experience by intelligently collecting and analyzing data. Figure 2 As shown, the AI ​​application framework in NR can include the following modules:

[0130] The data collection module is used to collect and store data from the next generation Node-B (gNB), gNB-central unit (CU), gNB-distributed unit (DU), UE or other management entities as a database for AI model training and data analysis and reasoning; the model training module analyzes the training data provided by the data collection module to provide the optimal AI model. The model inference module uses the AI ​​model to provide reasonable AI-based predictions for network operation based on the inference data provided by the data collection module, or guides the network to make policy adjustments. The decision / actor module executes the relevant policy adjustments output by the model inference module, and feeds back the specific performance of the network after the relevant policy is applied (such as various performance parameters) to the data collection module for storage.

[0131] Figure 3 This is another schematic diagram of AI application communication. Figure 2 The difference is that Figure 3 The AI ​​application communication framework shown in the figure includes, in addition to the data collection module, the model training module, and the model reasoning module, a model management module and a model storage module, which are used to manage and store AI models, respectively. Figure 3 Under the AI ​​application communication framework shown, the data collected by the data collection module can be used in the module training module, the model reasoning module and the model management module.

[0132] Currently, RAN1 is mainly researching the following three use cases for AI technology:

[0133] 1) Channel state information (CSI) feedback enhancement

[0134] 2) Beam management (BM)

[0135] 3) Positioning accuracy enhancements

[0136] In addition, the lifecycle management (LCM) of the AI ​​model is the management of the entire process of the AI ​​model from the beginning to the end. For example, in a communication system, the overall signaling process of the AI ​​model LCM between UE, RAN and core network (CN) or operation, administration and maintenance (OAM) (can be called network management) is as follows: Figure 4 As shown, it includes: AI-related capability interaction, data collection for AI model training, AI model training, AI model operation, data collection for AI model reasoning, AI model reasoning, AI model performance feedback / monitoring, AI model switching / update / deactivation / fallback and other processing processes.

[0137] For the above AI application scenarios, the input data of the AI ​​model are all AS data. For example, the input of the model in the CSI compression scenario is the channel state information reference signal (CSI-RS) measurement result, which involves access layer CSI reporting. If the UE's AS data is to be collected based on the EVEX data collection architecture, the ASP needs to send the configuration information for AS data collection based on the UE's AS capabilities. However, UE capabilities such as AS data collection capabilities are usually only reported to the RAN or access and mobility management function (AMF), and the ASP cannot perceive the UE AS data collection capabilities. Therefore, how to use the EVEX data collection architecture to realize the collection of UE's AS data has become an urgent problem to be solved.

[0138] In order to better understand the embodiments of the present application, the following explanations are made before introducing the embodiments of the present application.

[0139] First, in the embodiments of the present application, "used for indication" may include being used for direct indication and being used for indirect indication. When describing that a certain "indication information" is used to indicate A, it may include that the indication information directly indicates A or indirectly indicates A, but it does not mean that the indication information must carry A.

[0140] The information indicated by the indication information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each piece of information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each piece of information can also be identified and indicated uniformly to reduce the indication overhead caused by indicating the same information separately.

[0141] In addition, the specific indication method may also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of the various indication methods can refer to the prior art and will not be repeated herein. As can be seen from the above, for example, when it is necessary to indicate multiple information of the same type, different indication methods may be used for different information. In the specific implementation process, the desired indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood to cover various methods that can enable the party to be indicated to obtain the information to be indicated.

[0142] The information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or can be configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can include, for example, but not limited to, one or a combination of at least two of radio resource control (RRC) signaling, medium access control (MAC) layer signaling and physical layer signaling. Among them, MAC layer signaling, for example, includes MAC-control element (CE); physical (PHY) layer signaling, for example, includes DCI.

[0143] Second, in the embodiments of the present application, the first, second and various digital numbers are only used for the convenience of description and are not used to limit the scope of the embodiments of the present application. For example, to distinguish different indication information. For another example, the first indication information and the second indication information are only used to distinguish different areas, and their order is not limited. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not necessarily limit them to be different.

[0144] Third, in the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that under certain objective circumstances, the device (such as a terminal device or a network device) will make corresponding processing, which does not limit the time, and does not require the device (such as a terminal device or a network device) to have a judgment action when implementing it, nor does it mean that there are other limitations.

[0145] Meanwhile, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

[0153] Among them, CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH). It can be understood that the access network device can be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, CU can be divided into a network device in the access network RAN, and CU can also be divided into a network device in the CN, which is not limited here.

[0154] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open RAN (open-RAN, O-RAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU.

Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0155] In the embodiments of the present application, the form of the access network device is not limited. The device for realizing the function of the access network device may be the access network device; or it may be a device capable of supporting the access network device to realize the function, such as a chip system. The device may be installed in the access network device or used in conjunction with the access network device.

[0156] 3. Core network equipment

[0157] A core network device is a device deployed in a core network to provide services to terminal devices. In systems using different wireless access technologies, the names of core network devices with similar wireless communication functions may be different. In an embodiment of the present application, the core network device may be an access and mobility management network element. For example, when the method of an embodiment of the present application is applied to a 5G system, the access and mobility management network element may be an AMF. When the method of an embodiment of the present application is applied to an LTE system, the access and mobility management network element may be a mobility management entity (mobility management entity, MME). For the convenience of description only, in an embodiment of the present application, the above-mentioned devices that can provide services to terminal devices are collectively referred to as core network devices.

[0162] In the embodiment of the present application, an AI module may also be deployed on a terminal device, a network device or an application providing entity. The AI ​​module is a module with machine learning computing capabilities. When the AI ​​module is deployed on a communication device or a communication apparatus, the communication device or the communication apparatus may perform the above-mentioned Figure 2 or Figure 3 When the method of the embodiment of the present application is applied to a 5G system, such as Figure 6As shown, the AI ​​module is located in the OAM, or in the RAN device (the separation architecture is located in the CU / DU), in some terminal devices, or as a separate network element entity RAN intelligent controller (RIC) module. The main function of the AI ​​module in the wireless communication system is to perform a series of AI calculations such as model building, training approximation, and reinforcement learning based on input data (in the wireless communication system, the input data generally refers to the network operation data provided by the RAN side or monitored by the OAM, such as network load, channel quality, etc.). The trained model provided by the AI ​​module has the function of predicting network changes on the RAN side, and can usually be used for load prediction, UE trajectory 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 ​​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.

[0163] Furthermore, Figure 7 This is a schematic diagram of the architecture of a 5G system applicable to the above communication system provided in an embodiment of the present application. Figure 7 As shown, the 5G system includes: terminal equipment, access network (AN) and CN.

[0164] The above AN is used to implement access-related functions, can provide network access functions for authorized users in a specific area, and can determine transmission links of different qualities to transmit user data according to the user level, business requirements, etc. AN forwards control signals and user data between terminal devices and CN. AN can include: access network equipment, also known as RAN equipment.

[0165] The above CN is mainly responsible for maintaining the subscription data of the mobile network and providing functions such as session management, mobility management, policy management and security authentication for terminal devices.

[0167] It should be understood that the names of nodes, modules, devices or network elements in different scenarios, architectures or systems, as well as the names of communication interfaces between nodes, modules, devices or network elements are given by way of example in the embodiments of the present application, and the possibility of name changes in future communication systems, scenarios or architectures is not excluded.

[0168] The following will be combined Figure 8-Figure 11 The communication method provided in the embodiment of the present application is described in detail.

[0169] For example, Figure 8 A flow chart of a communication method provided in an embodiment of the present application. The communication method can be used for communication between a terminal device and a network device.

[0170] In an embodiment of the present application, the terminal device that executes the method embodiment may be the terminal device itself, or a component of the terminal device, such as a processor, chip, or chip system of the terminal device, or a logic module or software implementation that implements all or part of the functions related to the terminal device. The following method embodiment is described by taking the execution of the terminal device as an example. In an embodiment of the present application, the network device that executes the method embodiment may be the network device itself, or a component of the network device, such as a processor, chip, or chip system of the network device, or a logic module or software implementation that implements all or part of the functions related to the network device. The following method embodiment is described by taking the execution of the network device as an example. Figure 8 As shown, the communication method includes the following steps:

[0171] S801: A terminal device sends first capability information to a network device. Correspondingly, the network device receives the first capability information from the terminal device.

[0172] Among them, the first capability information is used to indicate the data collection capability supported by the AS of the terminal device (which may be referred to as AS data collection capability). In the embodiment of the present application, the first capability information reported by the terminal device may include all data collection capabilities possessed or supported by the AS of the terminal device, and may also include some data collection capabilities possessed or supported by the AS of the terminal device. Which data collection capabilities are specifically reported is related to the application scenario, the object of obtaining the data collection capability, etc.

[0173] The AS data collection capability includes: whether it supports sending AS data to the application layer of the terminal device. In other words, whether the AS of the terminal device supports sending AS data to the application layer (APP layer) of the terminal device. Normally, the AS and APP of the terminal device can confirm through negotiation that the AS of the terminal device can send data to the APP of the terminal device, or it is assumed that the AS of the terminal device can transmit AS data to the APP of the terminal device.

[0174] On this basis, the AS data collection capability may also include at least one of the following: the type of AS data supported to be sent to the application layer of the terminal device, the format of the AS data supported, or the object supported to obtain AS data. Among them, the type of AS data supported to be sent to the application layer of the terminal device may refer to: the AS of the terminal device supports sending AS data in one or more application scenarios (such as AI application scenarios such as CSI feedback enhancement, beam management, or positioning accuracy enhancement) to the application layer of the terminal device, or the AS of the terminal device supports sending which types of AS data to the application layer of the terminal device, etc. The object supported to obtain AS data may refer to: the object supported to open AS data, or the object supported to receive AS data, such as the direct data collection module that supports the terminal device (such as Figure 1DDCC in the module receives and sends AS data, supports indirect data collection modules provided by applications (such as Figure 1 IDCC in the receiving and sending AS data, supporting data collection application entity or application providing entity to obtain AS data, etc. It should be understood that the above exemplary data collection capabilities supported by the AS of several terminal devices are given, and the embodiments of the present application do not limit this.

[0175] In an embodiment of the present application, AS data may include but is not limited to the following: channel measurement data, layer (L) 1-reference signal receiving power (reference signal receiving power, RSRP), positioning reference signal (positioning reference signal, PRS) measurement data, sounding reference signal (sounding reference signal, SRS) measurement data, channel impulse response (channel impulse response, CIR) / channel frequency domain response (channel frequency response, CFR) data, channel power delay profile (power delay profile, PDP), model performance monitoring index data, or label data. Exemplarily, the channel measurement data includes at least one of some channel measurement raw data or processed data, such as the original channel matrix based on CSI-RS measurement, or the eigenvector data after decomposing the original channel matrix. Exemplarily, the model performance monitoring index data includes one or more of the channel prediction accuracy, Top-k beam prediction accuracy, positioning accuracy, and line of sight (line of sight, LOS) / non-line of sight (nonline of sight, NLOS) recognition accuracy. Exemplarily, the tag data includes one or more of a channel truth value, an optimal beam truth value, a terminal device position truth value, and a LOS / NOLS status truth value.

[0176] In a possible design, the network device may be an access network device or an access and mobility management network element. Figure 7 The RAN equipment in the access and mobility management network element can be the above Figure 7 In the case where the network device is an access and mobility management network element, the terminal device may send the first capability information to the access and mobility management network element through the access network device, or may directly send the first capability information to the access and mobility management network element, and there is no limitation on this.

[0177] In a possible design solution, the network device may be a data collection application entity. For example, the data collection application entity is the above Figure 1 In this design, the first capability information is based on the access network device or the access and mobility management network element authentication. That is to say, when the terminal device sends the data collection capability information to the data collection application entity, the access network device or the access and mobility management network element can manage and control the data collection capability information that the terminal device opens or exposes to the data collection application entity, such as whether the AS data collection capability of the terminal device can be opened to the data collection application entity, and which AS data collection capabilities can be opened to the data collection application entity, etc.

[0178] In one possible implementation, the access network device or the access and mobility management network element may determine the data collection capabilities supported by the AS of the terminal device that can be sent to the data collection application entity or the application providing entity. For example, when the access network device or the access and mobility management network element forwards the AS data collection capabilities reported by the terminal device to the data collection application entity, the AS data collection capabilities are filtered based on a preconfigured policy before being sent to the data collection application entity. In this case, the first capability information received by the data collection application entity is the first capability information after screening and processing by the access network device or the access and mobility management network element, that is, the received first capability information may be different from the first capability information sent by the terminal device. Alternatively, the access network device or the access and mobility management network element may negotiate with the terminal device to determine which AS data collection capabilities can be opened to the data collection application entity, and there is no limitation on this.

[0179] S802: The application providing entity sends a first configuration to the network device. Correspondingly, the network device receives the first configuration from the application providing entity.

[0180] Among them, the first configuration is used for the terminal device to collect the AS data expected by the application providing entity. In an embodiment of the present application, the application providing entity configures the terminal device to collect the AS data expected by the application providing entity by issuing the first configuration. In a possible design scheme, the first configuration may include an event (event) associated with the expected AS data, an event identifier (eventID), the type of expected AS data, etc. Among them, the event associated with the expected AS data is used to indicate the use or purpose of the expected AS data, such as for CSI feedback enhancement and beam management; the event identifier is used to identify the event associated with the expected AS data. The above examples give several parameters configured in the first configuration. In addition, other parameters related to AS data collection can also be configured in the first configuration, such as the data processing method of the expected AS data, the objects to which the expected AS data can be opened / exposed, the period for collecting AS data, etc., which are not limited.

[0181] Exemplarily, the format of the first configuration is as follows:

[0182] Event: xxx, such as event 1

[0183] Event ID: xxx, such as ID1

[0184] External / Internal Application Identification: xxx

[0185] Data access configuration files:

[0186] >Data processing instructions: xxx, such as instructions for performing singular value decomposition (SVD) processing on the original channel matrix measured based on CSI-RS, etc.

[0187] >Data openness restrictions: xxx, such as AS data can only be opened to application providers

[0188] Parameters to be collected (AS data expected to be collected): xx, such as the eigenvector after decomposition of the original channel matrix, L1-RSRP, reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR)

[0189] …

[0190] Among them, the data access configuration file includes data processing instructions and data opening restrictions. The data processing instructions are used to indicate what kind of processing the expected AS data is based on. For example, the expected AS data includes the eigenvectors after decomposition of the original channel matrix. The eigenvectors after decomposition of the original channel matrix are configured through the data processing instructions to be obtained based on singular value decomposition (SVD). The data opening restrictions are used to configure the objects to which the collected expected AS data can be opened. For example, the expected AS data collected by the terminal device can only be opened to the application providing entity.

[0191] When the network device is an access network device or an access and mobility management network element, the network device may receive the first configuration from the application providing entity through the data collection application entity. That is, the first configuration sent by the application providing entity is forwarded to the network device by the data collection application entity.

[0192] It should be understood that the embodiment of the present application does not limit the execution order of S801 and S802. S801 and S802 can be executed simultaneously, or S801 can be executed first or S802 can be executed first. There is no limitation on this.

[0193] S803: The network device determines, from the first configuration according to the first capability information, a configuration for AS data collection supported by the terminal device.

[0194] In an embodiment of the present application, after obtaining the first capability information and the first configuration, the network device screens or filters the first configuration according to the first capability information to determine which of the first configurations are configurations for AS data collection that the terminal device can support / execute / accept.

[0195] Exemplarily, the AS data collection capability of the terminal device includes: supporting the sending of RSRP, SINR, PRS / SRS measurement data to the application layer of the terminal device, and supporting the provision of entities and network analysis network elements to the application (such as the above Figure 7 NWDAF) opens AS data, the first configuration refers to the example in S802 above, the network device can determine according to the first capability information that the terminal device does not support the collection of eigenvectors and RSRQ after the original channel matrix is ​​decomposed, but supports the collection of L1-RSRP and SINR.

[0196] In the case where the network device is an access network device or an access and mobility management network element, after determining the configuration for AS data collection supported by the terminal device in the first configuration, the network device can send first feedback information to the data collection application entity, and accordingly, the data collection application entity receives the first feedback information from the network device. The first feedback information is used to feedback the configuration supported by the terminal device in the first configuration, such as which configurations in the first configuration the terminal device supports execution and which configurations the terminal device does not support execution.

[0197] In one possible scenario, the first feedback information is used to indicate some or all of the configurations supported by the terminal device in the first configuration. That is, the network device can use the first feedback information to feedback whether the terminal device supports all of the configurations in the first configuration or supports some of the configurations in the first configuration. For example, the first feedback information is indicated by 1 bit, and when the bit value is 1, it indicates that the terminal device supports all of the configurations in the first configuration, and when the bit value is 0, it indicates that the terminal device supports some of the configurations in the first configuration.

[0198] In another possible scenario, the network device can feed back to the data collection application entity through the first feedback information which specific configurations in the first configuration are supported by the terminal device and which configurations are not supported by the terminal device. The first feedback information may include at least one of the following: the configuration for AS data collection supported by the terminal device, the configuration for AS data collection not supported by the terminal device, or the reason why the terminal device does not support the configuration for AS data. Continuing with the above example, the first feedback information may include that the terminal device does not support the collection of eigenvectors and RSRQ after the decomposition of the original channel matrix, wherein the reason for not supporting the collection of eigenvectors after the decomposition of the original channel matrix is ​​that the AI ​​model on the terminal device side only accepts the original channel data as the input data for model training / inference, and does not support the eigenvectors after SVD decomposition as the input data for model training / inference, and does not support the collection of RSRQ because the terminal device does not have the ability to measure RSRQ, and supports the collection of L1-RSRP and SINR.

[0199] Therefore, the data collection application entity can determine the configuration supported by the terminal device in the first configuration according to the received first feedback information, and thus update the first configuration according to the first feedback information, such as deleting the configuration not supported by the terminal device in the first configuration, or adding the configuration supported by the terminal device, to obtain the second configuration. Among them, all configurations in the second configuration are supported by the terminal device. Furthermore, the data collection application entity sends the second configuration to the terminal device, and correspondingly, the terminal device receives the second configuration from the data collection application entity, so that the terminal device can complete the collection of corresponding AS data according to the second configuration. Exemplarily, the second configuration includes the following configurations, wherein the terminal device is configured to obtain the collected L1-RSRP and SINR based on the measurement of CSI-RS, and the terminal device is configured to collect L1-RSRP and SINR with a period of 100 milliseconds (millisecond, ms):

[0200] Event: Event 1

[0201] Event ID: ID1

[0202] External / Internal Application Identification: xxx

[0203] Parameters to be collected (AS data expected to be collected): L1-RSRP, SINR

[0204] Reference signal: CSI-RS

[0205] Collection cycle: 100ms

[0206] …

[0207] In this case, in a possible design, after the data collection application entity receives the first feedback information, the data collection application entity may further send the first feedback information to the application providing entity. Accordingly, the application providing entity receives the first feedback information from the data collection application entity so that the application providing entity determines which configurations issued by it can be executed by the terminal device. Specifically, the data collection application entity may send the first feedback information directly to the event usage module (such as Figure 1 At this time, the network device forwards the first feedback information to the application providing entity through the data collection application entity.

[0208] In a possible scenario, the network device may also directly send the first feedback information to the application providing entity. Specifically, the network device directly sends the first feedback information to the event using module of the application providing entity.

[0209] In the case where the network device is a data collection application entity, the network device directly updates the first configuration according to the configuration for AS data collection supported by the terminal device in the first configuration, obtains the second configuration, and sends the second configuration to the terminal device. It can also be understood that the network device updates the first configuration according to the data collection capability supported by the AS of the terminal device, and obtains the configuration matching the capability of the terminal device (i.e., the second configuration).

[0210] Based on the above solution, it can be known that the update of the first configuration is performed by the data collection application entity, and the data collection application entity sends the second configuration (the updated first configuration) to the terminal device.

[0211] In one possible design scheme, the data collection application entity may directly send the second configuration to the terminal device, and accordingly, the terminal device receives the second configuration from the data collection application entity. Specifically, the data collection application entity sends the second configuration to the direct data collection module of the terminal device, and after receiving the second configuration, the direct data collection module sends the second configuration to the application layer of the terminal device, and then the application layer of the terminal device sends the second configuration to the AS of the terminal device, so that the AS of the terminal device collects the AS data expected by the application providing entity according to the second configuration. Accordingly, after collecting the AS data expected by the application providing entity, the AS of the terminal device can send the AS data to the data collection application entity through the application layer and the direct data collection module of the terminal device, and then the data collection application entity opens the collected AS data to the application providing entity or other entities (such as network analysis network elements).

[0212] In another possible design scheme, the data collection application entity may send the second configuration to the terminal device through the application providing entity. In other words, the second configuration may be forwarded to the terminal device through the application providing entity. Specifically, the data collection application entity sends the second configuration to the indirect data collection module of the application providing entity, and the indirect data collection module then sends the second configuration to the AS of the terminal device, so that the AS of the terminal device collects the AS data expected by the application providing entity according to the second configuration. Accordingly, after the AS of the terminal device sends the collected AS data to the application layer, it may send the AS data to the data collection application entity or other entities through the indirect data collection module of the application providing entity. The specific implementation process can be found in the following Fig. 9 The method embodiments shown are not described in detail here.

[0213] In an embodiment of the present application, after the data collection application entity obtains the AS data reported by the terminal device, the data collection application entity opens the collected AS data to other entities based on the event open subscription process, such as a network analysis network element or an application provider entity initiating an event open subscription request to the data collection application entity, and the event open subscription request carries an event identifier associated with the AS data to be obtained. After the data collection application entity obtains the AS data associated with the corresponding event, it sends the AS data associated with the event to the network analysis network element or the application provider entity.

[0214] based on Figure 8 In the communication method shown, the network device senses the data collection capability supported by the AS of the terminal device, screens and processes the AS data collection configuration (such as the first configuration) sent to the terminal device by the application provider entity, and filters out the data collection configuration that the terminal device cannot support in the first configuration, so that the data collection capability supported by the AS of the terminal device is adapted to the sent configuration, thereby enhancing the network device's control over the collected AS data and related configurations, thereby realizing the collection of AS data, and then the collected AS data can be opened to the application provider entity or other network entities, so that the application provider entity or other network entities can complete related event processing based on the open AS data, thereby realizing the effective use of AS data.

[0215] It should be understood that in the embodiments of the present application, the terminal device collecting AS data may include measuring AS data and performing related processing on the measured AS data, and there is no limitation on this.

[0216] For ease of understanding, the following Figure 1 The EVEX architecture is shown as well Figure 7 The 5G system shown Figure 8The specific implementation process of the communication method shown is described in detail. For example, taking the terminal device as UE, the network device as RAN device, the application providing entity as ASP, and the data collection application entity as DCAF as an example, the communication method provided in the embodiment of the present application is described in detail. Fig. 9 As shown, the communication method includes the following steps:

[0217] S900 and APP negotiate with AS for AS data collection.

[0218] Exemplarily, the APP in the UE and the AS confirm through negotiation that the AS can send data to the APP, and the APP confirms that the data collected by the AS can be packaged and sent to the DCAF using the EVEX framework.

[0219] S901: The AS sends first capability information to a RAN device. Correspondingly, the RAN device receives the first capability information from the AS.

[0220] The specific description of the first capability information may refer to the relevant description in the above S801, which will not be repeated here. Exemplarily, the first capability information includes that the AS supports sending AS data to the APP, and the types of AS data supported include L1-RSRP and SINR.

[0221] Before executing S902, in the embodiment of the present application, processes such as application function registration (AF registration) and DCAF discovery (discover DCAF) may also be executed. Application function registration mainly involves the interaction between network elements or functions or modules such as NRF, DCAF, and NWDAF, and DCAF discovery mainly involves the interaction between network elements or functions or modules such as NRF and PAF. The specific implementation process can refer to the relevant description in the existing implementation method, which will not be described in detail. Among them, the application function registration, DCAF discovery and other processes can be executed before or after S901 or simultaneously with S901, without limitation.

[0222] S902: PAF sends a first configuration to DCAF. Correspondingly, DCAF receives the first configuration from PAF.

[0223] Among them, the first configuration is used for UE to collect AS data expected by ASP. The first configuration can be carried in the data reporting configuration (Ndcad_DataReportingProvisioning) message and sent to DCAF through the R1 interface. For the specific description of the first configuration, please refer to the relevant description in S802 above, which will not be repeated here. Exemplarily, the first configuration includes that ASP expects UE to collect L1-RSRP and RSRQ, the event associated with L1-RSRP and RSRQ is event 1, and the event identifier of event 1 is ID1, etc.

[0224] It should be understood that PAF can send configuration to DCAF through R1 interface to assume that DCAF / ASP is in the trust domain. If DCAF / ASP is outside the trust domain, authentication and authorization need to be performed through NEF.

[0225] S903: The DCAF sends a first configuration to the RAN device. Correspondingly, the RAN device receives the first configuration from the DCAF.

[0226] S904: The RAN device determines, from the first configuration, a configuration for AS data collection supported by the UE according to the first capability information.

[0227] Exemplarily, the RAN device can determine, based on the first capability information, that the AS supports sending AS data to the APP, and the types of supported AS data include L1-RSRP and SINR, while in the first configuration, the ASP expects the UE to collect L1-RSRP and RSRQ. Therefore, the RAN device can determine that the UE does not support the collection of RSRQ, and thus can determine that the configuration for AS data collection supported by the UE in the first configuration includes support for collecting L1-RSRP.

[0228] S905: The RAN device sends first feedback information to the DCAF. Correspondingly, the DCAF receives the first feedback information from the RAN device.

[0229] Exemplarily, after executing S904, the RAN device feeds back, through first feedback information, which configurations in the first configuration are executable by the UE and which configurations are not executable by the UE, such as the first feedback information includes a configuration in which the UE supports collecting L1-RSRP but does not support collecting RSRQ.

[0230] S906: The DCAF sends the second configuration to the DDCC. Correspondingly, the DDCC receives the second configuration from the DACF.

[0231] The second configuration is updated according to the first feedback information. Exemplarily, after receiving the first feedback information, the DCAF updates the first configuration according to the first feedback information, such as deleting the configuration of AS data not supported by the UE in the first configuration, and obtaining the second configuration, which is a configuration for AS data collection supported by the UE, such as the second configuration includes that the ASP expects the UE to collect L1-RSRP, the event associated with L1-RSRP is event 1, and the event identifier of event 1 is ID1, etc.

[0232] S907: DDCC sends the second configuration to APP. Correspondingly, APP receives the second configuration from DDCC.

[0233] S908: The APP sends the second configuration to the AS. Correspondingly, the AS receives the second configuration from the APP.

[0234] Based on the above S907 to S908, the AS in the UE obtains the second configuration from the DCAF through DDCC and APP, and collects AS data (such as L1-RSRP) according to the second configuration. Further, after collecting the AS data, the AS can send the collected AS data to the DCAF through APP and DDCC.

[0235] In a possible design, DDCC can also send the collected AS data to RAN equipment by calling data reporting service (Ndcaf_DataReporting service), and then the RAN equipment sends it to DCAF. Alternatively, after receiving the AS data sent by AS, APP sends it to IDCC in ASP through R8 interface, and then IDCC sends the AS data to DCAF through R3 interface.

[0236] Therefore, DCAF can obtain the AS data associated with different events based on the above process, and can expose the collected AS data of different events to other entities, functions or modules, such as ECAF, NEF, NWDAF, etc. in ASP, based on the event exposure subscription process. For example, ECAF subscribes to the AS data related to event 1 from DCAF, and DCAF sends the AS data related to event 1 to ECAF according to the identifier of event 1, so that ECAF completes event 1 based on the AS data related to event 1.

[0237] based on Fig. 9 In the communication method shown, the RAN device senses the AS data collection capability of the UE, and based on the AS data collection capability of the UE, screens the AS data collection configuration sent by the ASP, and provides the UE with a suitable configuration to implement AS data reporting.

[0238] In addition, the embodiment of the present application also provides a communication method, in which the network device does not filter the AS data collection configuration sent by the application providing entity, but matches the AS data collection configuration sent by the application providing entity based on the AS data collection capabilities of different terminal devices, and sends the AS data collection configuration suitable for each terminal device to the terminal device to perform AS data collection. For example, Fig.10 As shown, taking the network device as an access network device (such as a RAN device) or an access and mobility management network element (such as an AMF) as an example, the communication method includes the following steps:

[0239] S1001: A first terminal device sends first capability information to a network device. Correspondingly, the network device receives the first capability information from the first terminal device.

[0240] Among them, the first capability information is used to indicate the data collection capability supported by the AS of the first terminal device. For the relevant description of the first capability information, please refer to the relevant description in the above S801, which will not be repeated here. For example, the first capability information of the first terminal device indicates that the AS of the first terminal device only supports the collection of L1-RSRP. The first capability information corresponding to different terminal devices is different. For example, the first capability information of the second terminal device indicates that the AS of the second terminal device only supports the collection of channel impulse responses.

[0241] S1002: The application providing entity sends one or more configuration groups to the network device. Correspondingly, the network device receives one or more configuration groups from the application providing entity.

[0242] Among them, each group of configurations in one or more groups of configurations can be used by the terminal device to collect the AS data expected by the application providing entity, and the AS data expected to be collected configured in one or more groups of configurations are different. For example, the application providing entity sends three groups of configurations to the network device, configuration 1 is used to configure the terminal device to collect L1-RSRP, configuration 2 is used to configure the terminal device to collect channel impulse response, and configuration 3 is used to configure the terminal device to collect LOS / NLOS tag data. In an embodiment of the present application, in addition to the AS data expected to be collected, each group of configurations may also include event information associated with the AS data expected to be collected. For a specific description, please refer to the relevant description of the first configuration in S802 above, which will not be repeated here. Exemplarily, the application providing entity is the above Figure 1 In the ASP, one or more groups of configurations can be issued by the PAF in the ASP.

[0243] It should be understood that among the multiple groups of configurations, there may be at least two groups of configurations that include partially identical configurations, such as configuration 1 is used to configure the terminal device to collect L1-RSRP and RSRQ, and configuration 2 is used to configure the terminal device to collect L1-RSRP and SINR, and the configurations for collecting L1-RSRP in configuration 1 and configuration 2 are the same.

[0244] In a possible design, the application providing entity sends one or more configurations to the network device through the data collection application entity. That is, the configuration sent by the application providing entity is forwarded to the network device through the data collection application entity. For example, the data collection application entity is the above Figure 1 DCAF in.

[0245] S1003: The network device determines a second configuration from one or more groups of configurations according to the first capability information.

[0246] The second configuration is a configuration for AS data collection supported by the first terminal device. Exemplarily, the network device determines that the first terminal device only supports the collection of L1-RSRP based on the first capability information. Referring to the example in S1002 above, it can be determined that configuration 1 matches the AS data collection capability of the first terminal device, thereby determining configuration 1 as the second configuration. It should be understood that the AS data collection capability of the first terminal device may match one or more groups of configurations.

[0247] S1004: The network device sends a second configuration to the first terminal device. Correspondingly, the first terminal device receives the second configuration from the network device.

[0248] In one possible design scheme, the network device sends the second configuration to the first terminal device through the data collection application entity.

[0249] In an embodiment of the present application, after receiving the second configuration, the first terminal device collects AS data according to the second configuration, and sends the collected AS data to the data collection application entity. For example, after the first terminal device collects L1-RSRP, it reports L1-RSRP to the data collection application entity. The AS data reporting process of the first terminal device and the process of how the data collection application entity opens the AS data to other entities after obtaining it can be found in the relevant description in S803 or S908 above, which will not be repeated here.

[0250] Furthermore, the communication method provided in the embodiment of the present application may also include the following steps:

[0251] S1005: The network device sends second feedback information to the data collection application entity. Correspondingly, the data collection application entity receives the second feedback information from the network device.

[0252] The second feedback information is used to indicate the AS data collection status corresponding to the configuration executed by the terminal device in one or more configuration groups. That is, the network device uses the second feedback information to feedback which configurations in one or more configuration groups are executed by the terminal device, that is, which AS data collection is completed based on which configurations by the terminal device.

[0253] In an embodiment of the present application, the second feedback information may include at least one of the following: AS data that has been collected, AS data that has not been collected, or the reason for the incomplete collection of AS data. Exemplarily, in the three groups of configurations (configurations 1 to 3) issued by the application providing entity, the first terminal device completes the collection of L1-RSRP based on configuration 1, the second terminal device completes the collection of channel impulse response based on configuration 2, and configuration 3 is not matched to a terminal device with the capability to execute. Therefore, the network device can determine that the AS data that has been collected includes L1-RSRP and channel impulse response, and the AS data that has not been collected includes LOS / NLOS tag data. The reason for the incomplete collection of LOS / NLOS tag data is that there is no terminal device that supports LOS / NLOS tag data collection among the terminal devices that report the AS data collection capability, so as to inform the data collection application entity through the second feedback information.

[0254] S1006: The data collection application entity sends second feedback information to the application providing entity. Correspondingly, the application providing entity receives the second feedback information from the data collection application entity.

[0255] Specifically, the data collection application entity informs the application providing entity of the execution status of the AS data collection configuration issued by it through the second feedback information.

[0256] based on Fig.10 In the communication method shown, the network device matches the configuration that can be executed based on the capabilities of the terminal device from one or more groups of configurations issued by the application providing entity according to the AS data collection capability reported by the terminal device, and sends it to the terminal device to complete the collection of AS data.

[0257] Above Figure 8 to Figure 10 In the communication method shown, the access network device (such as RAN device) or the access and mobility management network element (such as AMF) or the data collection application entity (such as DCAF) can sense the AS data collection capability of the terminal device, match or filter the appropriate AS data collection configuration for the terminal device, and thus realize the collection of AS data. In addition, the application providing entity can also sense or obtain the AS data collection capability of the terminal device, and directly send the matching configuration to the terminal device based on the AS data collection capability of the terminal device, so as to realize the collection of AS data.

[0258] For example, Fig.11 A flow chart of another communication method provided in an embodiment of the present application. Fig.11 As shown, the communication method includes the following steps:

[0259] S1101: A terminal device sends first capability information to an application providing entity. Correspondingly, the application providing entity receives the first capability information from the terminal device.

[0260] The first capability information is used to indicate the data collection capability supported by the AS of the terminal device. At this time, the data collection capability supported by the AS reported by the terminal device may be all or part of the data collection capability supported by the AS of the terminal device.

[0261] In a possible design, before executing S1101, the AS data collection capability reported by the terminal device needs to be authenticated by the network device (such as the access network device or the access and mobility management network element). In other words, the network device can control the data collection capability information of the terminal device that is open or exposed to the application providing entity, such as whether the AS data collection capability of the terminal device can be opened to the application providing entity, and which AS data collection capabilities can be opened to the application providing entity, etc.

[0262] In a possible implementation, the network device can negotiate with the terminal device to determine which AS data collection capabilities can be opened to the application providing entity, and the first capability information reported by the terminal device is authenticated. Alternatively, in the process of forwarding the first capability information to the application providing entity, the network device filters the AS data collection capabilities based on the preconfigured policy before sending it to the application providing entity. In this case, the first capability information received by the application providing entity is the first capability information after screening and processing by the network device, that is, the received first capability information may be different from the first capability information sent by the terminal device.

[0263] In a possible design scheme, the terminal device may send the first capability information to the application providing entity via the network device and the data collection application entity in sequence.

[0264] Optionally, the terminal device may also send its application layer related capability information to the application providing entity, such as the capability of supporting application layer encapsulation of data collected by the AS.

[0265] S1102: The application providing entity determines a second configuration according to the first capability information.

[0266] Among them, the second configuration is a configuration for AS data collection supported by the terminal device. Exemplarily, after receiving the first capability information, the application providing entity can directly customize the configuration information for it according to the AS data collection capability supported by the terminal device, that is, the second configuration, so that the issued configuration matches the data collection capability of the terminal device. For example, the terminal device supports the collection of L1-RSRP and RSRQ, but does not support the collection of channel impulse response. The second configuration can configure the terminal device to collect L1-RSRP and / or RSRQ. Exemplarily, the application providing entity is the above Figure 1 In the ASP, the second configuration can be configured and issued by the PAF in the ASP.

[0267] S1103: The application providing entity sends a second configuration to the terminal device. Correspondingly, the terminal device receives the second configuration from the application providing entity.

[0268] Exemplarily, the application providing entity may forward the second configuration to the terminal device through the data collection application entity. Thus, the terminal device may complete the collection of corresponding AS data according to the second configuration. The sending process of the second configuration and the reporting process of the AS data may refer to the relevant description in S803 or S906 to S908 above, which will not be repeated here.

[0269] based on Fig.11 In the communication method shown, the application providing entity can directly configure a suitable AS data collection configuration for the terminal device by sensing the AS data collection capability of the terminal device, thereby realizing the collection of AS data.

[0270] It can be understood that in each of the above embodiments, the methods and / or steps implemented by the network device can also be implemented by components that can be used for the network device (such as processors, chips, chip systems, circuits, logic modules, or software); the methods and / or steps implemented by the data collection application entity can also be implemented by components that can be used for the data collection application entity (such as processors, chips, chip systems, circuits, logic modules, or software); the methods and / or steps implemented by the application providing entity can also be implemented by components that can be used for the application providing entity (such as processors, chips, chip systems, circuits, logic modules, or software); the methods and / or steps implemented by the terminal device can also be implemented by components that can be used for the terminal device (such as processors, chips, chip systems, circuits, logic modules, or software).
