[0002] This application claims priority to Chinese Patent Application No. 202510065013.5, filed on January 15, 2025, entitled "Transmission Method, Apparatus, Communication Equipment and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to a transmission method, apparatus, communication equipment, and storage medium. Background Technology

[0004] Artificial intelligence (AI) has been widely applied in various fields. For certain AI models, network-side devices can collect data for training these models. For example, network-side devices can be configured to collect data from terminals and then use that data to train the model.

[0005] Currently, network-side devices can configure terminals to perform data acquisition and reporting through the Radio Resource Control (RRC) measurement process. In the RRC measurement process, the configuration for data acquisition and reporting is sent to the terminal by the network-side device currently serving the terminal, and reports can only be sent to the network-side device currently serving the terminal. This ensures that the data collected by the terminal can only be reported to the network-side device currently serving the terminal.

[0006] When a terminal collects and stores data configured by a network-side device, if the network-side device used to configure the terminal to collect data is changed before being reported to the network-side device that configured the terminal to collect data, the terminal may delete the stored data. As a result, the network-side device that originally configured the terminal to collect data will not be able to obtain the data collected by the terminal, which leads to a decrease in data collection efficiency and wastes the terminal's storage resources.

[0051] In this embodiment, when the measurement result of the terminal's reference signal meets a first condition, the terminal sends first indication information to a first network-side device, the first network-side device being the network-side device serving the terminal, and the first indication information is used to indicate that first data is available; and / or, after the network-side device serving the terminal is changed to a second network-side device, the terminal sends the first data and the identification information of the first network-side device to the second network-side device; wherein, the first data includes data collected by the terminal as instructed by the first network-side device.

[0076] To facilitate understanding of the transmission method in the embodiments of this application, the following related content will be introduced first:

[0077] I. Introduction to CSI Compression Based on Artificial Intelligence (AI) / Machine Learning (ML)

[0078] Artificial intelligence is currently widely used in various fields. Among them, AI units can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers.

[0079] The term "AI model" can also be referred to as an AI unit, ML model, ML unit, AI structure, AI function, AI characteristic, machine learning model, neural network, neural network function, neural network functionality, etc. Alternatively, the AI ​​unit / AI model can refer to a processing unit capable of implementing specific algorithms, formulas, characteristics, processing flows, capabilities, etc., related to AI.

This application does not impose specific limitations in this regard. Optionally, the specific dataset includes the input and / or output of the AI ​​unit / AI model.

[0080] II. Minimization of Drive Tests (MDT)

[0081] To ensure network quality, operators need to use drive tests. Traditional drive testing involves operators deploying dedicated personnel and specialized equipment to test signal quality at various locations within the actual network to check for coverage issues. However, this method is not only resource-intensive, but also ineffective because drive test personnel cannot easily access all locations to test network signal quality.

[0082] To address the aforementioned issues, the Third Generation Partnership Projects (3GPP) proposed the MDT (Multi-User Test) technology. This technology directly uses user equipment (UEs) within the network to measure and report network coverage. The advantage of this approach is that it allows users to directly test network coverage, avoiding significant manpower and material costs for operators. Furthermore, it can cover any location within the network that users can actually reach, making it more effective than traditional drive testing methods in terms of coverage range.

[0083] MDT (Multi-Drive Testing) technology boasts advantages such as low overhead and short optimization cycles, significantly reducing the cost of network optimization and maintenance for telecommunications operators and improving the efficiency of network optimization. Simultaneously, MDT technology can collect network information from locations inaccessible by traditional drive testing (such as indoors and narrow roads). Therefore, MDT technology can provide stronger support for evaluating network performance and improving network quality, ultimately leading to higher user satisfaction.

[0084] From the perspective of MDT measurement methods, MDT can be divided into immediate MDT and logged MDT:

[0085] The characteristics of Immediate MDT are as follows: the UE performs measurements in RRC connected state, using the existing Radio Resource Management (RRM) measurements in the multiplexing protocol. If the configured reporting conditions are met, the UE will report the MDT measurement results to the base station. When the UE switches to another cell, the target cell can release the MDT configuration based on the trace configuration (e.g., the trace configuration indicates that immediate MDT is no longer needed, or the target cell has not received the trace configuration). When the UE enters RRC idle state, its Immediate MDT configuration is also released.

[0086] The characteristics of Logged MDT are: the base station configures Logged MDT measurements for the UE when the UE is in RRC connected state. The UE can only perform measurements and record the results in RRC idle / inactive state. The UE can only report the results to the base station after returning to RRC connected state. Logged MDT measurements continue after being configured until the configured duration is reached.

[0087] In addition, from the perspective of the objects collected by MDT, MDT can be divided into management-based MDT and signaling-based MDT:

[0088] Management-based MDT: This involves collecting MDT data of UEs within a specific area (such as a tracking area or cell). MDT requests and configurations are sent directly from Operation Administration and Maintenance (OAM) to the base station.

[0089] Signaling-based MDT: This involves collecting MDT data for a specific UE, which can be specified by the user identifier / device identifier.

[0090] III. AI / ML Architecture

[0091] The main process of an AI / ML architecture for air interface AI can be shown in Figure 2.

[0092] Data collection: used to provide input data for model training, management, and inference;

[0093] Model Training: Used to perform AI / ML model training, validation, and testing; also responsible for data preparation, i.e., data preprocessing, converting data into specific formats, etc.

[0094] Management: Used for model selection / activation / deactivation / switching / rollback, etc.

[0095] Inference: Used to apply model input to AI / ML models or AI / ML functions to obtain the corresponding model output;

[0096] Model Storage: Used to save trained / updated models;

[0097] Model Transfer / Delivery: Used to deliver AI / ML models to inference function nodes.

[0098] IV. Data Collection

[0099] For base station (gNB) side models, there are two methods for collecting network-side data for model training:

[0100] Option 1: Data acquisition on the gNB side (i.e., based on Layer 3 signaling), that is, the gNB configures the terminal to collect data and obtain the collected data; then, the gNB uses the collected data to train the model.

[0101] Option 2: OAM-side data acquisition (i.e., based on Minimum Drive Test MDT), where OAM collects data through the gNB-configured terminal and sends the collected data to OAM; then, OAM trains a model based on the collected data and sends the model to gNB.

[0102] For both of the above schemes, the interaction process between the UE and gNB will be designed to be as unified as possible. OAM-side data collection will be enhanced based on the existing Immediate MDT, meaning it will support data storage on the terminal and indicate to the network that data is available, after which the network will request data as needed.

[0103] The transmission method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0104] Referring to Figure 3, an embodiment of this application provides a transmission method, which may include the following steps 301 and / or 302:

[0105] Step 301: If the measurement result of the terminal's reference signal meets the first condition, the terminal sends the first indication information to the first network-side device.

[0106] Wherein, the first network-side device is a network-side device serving the terminal; the first indication information is used to indicate that the first data is available; here, the first data includes data collected by the terminal at the instruction of the first network-side device. It can be seen that, in some embodiments of this application, if the measurement result of the terminal's reference signal meets a first condition, the terminal can report the availability of the first data to the first network-side device.

[0107] It should be noted that the first indication information can be understood as a data availability indication; the data collected by the terminal by the first network-side device can be understood as: at least part of the data collected by the terminal by the first network-side device; the first network-side device is the network-side device of the current serving terminal, or it can also be understood as the network-side device corresponding to the source cell before the terminal performs cell handover.

[0108] In some embodiments, the first condition is used to indicate the condition that the measurement result of the reference signal is satisfied when the terminal is at the cell edge. Thus, the measurement result of the terminal's reference signal satisfying the first condition can be understood as the terminal being at the cell edge. In this case, the terminal sends a first indication message to the first network-side device to inform the first network-side device that the first data is available, so as to assist the first network-side device in requesting the first data. In this way, the first network-side device can obtain the first data before the terminal performs cell handover, thereby avoiding the situation where the network-side device corresponding to the source cell (i.e., the first network-side device) cannot obtain the data it instructed the terminal to collect after the terminal performs cell handover.

[0109] Alternatively, in some embodiments, the first condition can be understood as a more lenient condition than the cell handover condition, so that the terminal can trigger the reporting of the first indication information before triggering the measurement report for handover.

[0110] Step 302: After the network-side device serving the terminal is changed to the second network-side device, the terminal sends the first data and the identification information of the first network-side device to the second network-side device.

[0111] The first data includes data collected by the terminal at the instruction of the first network-side device. Therefore, in some embodiments of this application, after the network-side device of the serving terminal is changed to a second network-side device, the terminal can report to the second network-side device the data collected by the terminal at the instruction of the first network-side device and the identification information of the first network-side device. It can be understood that the data collected by the terminal at the instruction of the first network-side device can also be interpreted as at least a portion of the data collected by the terminal at the instruction of the first network-side device.

[0112] In addition, after the terminal sends the first data and the identification information of the first network-side device to the second network-side device, the second network-side device can forward the first data to the first network-side device.

[0113] In addition, it should be noted that the second network-side device can be understood as the network-side device corresponding to the target cell after the terminal performs cell handover.

[0114] Optionally, the first data and the identification information of the first network-side device can be sent independently; or they can be sent together, for example, when the terminal sends the first data to the second network-side device, the identification information of the first network-side device is carried in the first data.

[0115] As can be seen from steps 301 to 302 above, when the network-side device of the serving terminal is the first network-side device (e.g., before the network-side device of the serving terminal is changed, or when the network-side device of the serving terminal is not changed), if the measurement result of the terminal's reference signal meets the first condition, that is, when there is a possibility that the first network-side device is changed, then the terminal can report first indication information to the first network-side device to inform the first network-side device that it indicates the first data collected by the terminal is available. Therefore, in the embodiments of this application, when the network-side device of the serving terminal is the first network-side device, the condition that the terminal reports the availability of data to the first network-side device currently serving it is added to assist the first network-side device in requesting the first data collected by the terminal.

[0116] And / or, after the network-side device of the service terminal is changed to the second network-side device, the terminal may also report the first data collected by the terminal at the instruction of the first network-side device and the identification information of the first network-side device to the second network-side device. In this way, after the second network-side device receives the first data, it can know the network-side device that instructed the collection of the first data, so as to assist the second network-side device in providing the first data to the first network-side device.

[0117] As can be seen from the above, in this embodiment of the application, when the network-side device of the service terminal is the first network-side device, by adding the condition that the terminal can report data, and / or after the network-side device of the service terminal is changed to the second network-side device, the terminal reports the first data and the identification information of the first network-side device to the second network-side device, the first network-side device can be assisted in obtaining the first data. In this way, even if the network-side device of the service terminal is changed, the first network-side device that originally instructed the terminal to collect data can still obtain the first data collected by the terminal, which improves the overall efficiency of the first network-side device in obtaining the collected data, thereby enabling the first network-side device to train the corresponding AI model based on the first data.

[0118] Optionally, the measurement results of the reference signal include the measurement results of the serving cell of the terminal and / or the measurement results of the neighboring cells of the terminal;

[0119] The first condition includes at least one of the following A-1 to A-3:

[0120] Item A-1: ​​First event, used to indicate that the measurement result of the serving cell is less than or equal to a first threshold;

[0121] Item A-2: A second event, used to indicate that the difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to a second threshold; wherein the second threshold can be a positive or negative value.

[0122] It should be noted that the difference between A and B in this article is AB.

[0123] Item A-3: Third event, used to indicate that the measurement result of the neighboring cell is greater than or equal to a third threshold.

[0124] It should be noted that when the first condition includes at least one of the first event, the second event, and the third event, the terminal satisfies the first condition, which can be understood as the terminal satisfying at least one of the first event, the second event, and the third event. That is, in some embodiments, when the terminal satisfies at least one of the first event, the second event, and the third event, the terminal sends the aforementioned first indication information to the first network-side device.

[0125] In some embodiments, by determining whether the terminal satisfies at least one of the first event, the second event, and the third event, it can be determined whether the terminal is at the cell edge; or, in some embodiments, by determining whether the terminal satisfies at least one of the first event, the second event, and the third event, it can be determined whether the terminal is about to perform a cell handover.

[0126] Optionally, the method further includes:

[0127] The terminal determines whether the measurement result of the terminal's reference signal meets the first condition based on the first information.

[0128] The first information includes at least one of the following A-4 to A-12:

[0129] Item A-4: The measurement trigger threshold for the first event;

[0130] Item A-5: Hysteresis parameter of the first event; Optionally, the hysteresis parameter of the first event can be configured to 0 (i.e., the hysteresis parameter of the first event can be left unconfigured);

[0131] Item A-6: Duration threshold of the first event; Optionally, the duration threshold of the first event can be configured to 0 (i.e., the duration threshold of the first event can be left unconfigured).

[0132] Specifically, based on at least one of A-4 to A-6, it can be determined whether the terminal satisfies the first event (i.e., whether the measurement result of the terminal's serving cell is less than or equal to the first threshold).

[0133] Optionally, the first event is satisfied under at least one of the following conditions:

[0134] The measurement result of the serving cell is less than or equal to the measurement trigger threshold of the first event;

[0135] The measurement result of the serving cell is less than or equal to the sum of the measurement trigger threshold of the first event and the hysteresis parameter of the first event;

[0136] Alternatively, the first event is satisfied under one of the following conditions:

[0137] The measurement result of the serving cell is less than or equal to the measurement trigger threshold of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event.

[0138] The measurement result of the serving cell is less than or equal to the sum of the measurement trigger threshold of the first event and the hysteresis parameter of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event.

[0139] The measurement result of the serving cell is less than or equal to the measurement trigger threshold of the first event, and the measurement result of the serving cell is less than or equal to the sum of the measurement trigger threshold of the first event and the hysteresis parameter of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event.

[0140] Item A-7: The measurement trigger threshold for the second event;

[0141] Item A-8: Hysteresis parameter of the second event; Optionally, the hysteresis parameter of the second event can be configured to 0 (i.e., the hysteresis parameter of the second event can be left unconfigured);

[0142] Item A-9: Duration threshold of the second event; optionally, the duration threshold of the second event can be configured to 0 (i.e., the duration threshold of the second event can be left unconfigured).

[0143] Specifically, based on at least one of A-7 to A-9, it can be determined whether the terminal satisfies the second event (i.e., whether the difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the second threshold).

[0144] Optionally, the second event is satisfied under at least one of the following conditions:

[0145] The difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the measurement trigger threshold of the second event;

[0146] The difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the sum of the measurement trigger threshold of the second event and the hysteresis parameter of the second event;

[0147] Alternatively, the second event is satisfied under one of the following conditions:

[0148] The difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the measurement trigger threshold of the second event, and the duration of the second event is greater than or equal to the duration threshold of the second event.

[0149] The difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the sum of the measurement trigger threshold of the second event and the hysteresis parameter of the second event, and the duration of the second event is greater than or equal to the duration threshold of the second event.

[0150] The difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the measurement trigger threshold of the second event, and the difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the sum of the measurement trigger threshold of the second event and the hysteresis parameter of the second event, and the duration of the second event is greater than or equal to the duration threshold of the second event.

[0151] Item A-10: The measurement trigger threshold for the third event;

[0152] Item A-11: The hysteresis parameter of the third event; optionally, the hysteresis parameter of the third event can be configured to 0 (i.e., the hysteresis parameter of the third event can be left unconfigured);

[0153] Item A-12: The duration threshold of the third event; optionally, the duration threshold of the third event can be configured to 0 (i.e., the duration threshold of the third event can be not configured).

[0154] Among them, based on at least one of A-10 to A-12, it can be determined whether the terminal satisfies the third event (i.e., whether the measurement result of the terminal's neighboring cell is greater than or equal to the third threshold).

[0155] Optionally, the third event is satisfied under at least one of the following conditions:

[0156] The measurement result of the neighboring cell is greater than or equal to the measurement trigger threshold of the third event;

[0157] The measurement result of the neighboring cell is greater than or equal to the sum of the measurement trigger threshold of the third event and the hysteresis parameter of the third event;

[0158] Alternatively, the third event is satisfied under one of the following conditions:

[0159] The measurement result of the neighboring cell is greater than or equal to the measurement trigger threshold of the third event, and the duration of the third event is greater than or equal to the duration threshold of the third event;

[0160] The measurement result of the neighboring cell is greater than or equal to the sum of the measurement trigger threshold of the third event and the hysteresis parameter of the third event, and the duration of the third event is greater than or equal to the duration threshold of the third event.

[0161] The measurement result of the neighboring cell is greater than or equal to the measurement trigger threshold of the third event, and the measurement result of the neighboring cell is greater than or equal to the sum of the measurement trigger threshold of the third event and the hysteresis parameter of the third event, and the duration of the third event is greater than or equal to the duration threshold of the third event.

[0162] Optionally, when the measurement result of the terminal's reference signal meets the first condition, the terminal sends first indication information to the first network-side device, including:

[0163] If the terminal has available data and the measurement result of the terminal's reference signal meets the first condition, the terminal sends the first indication information to the first network-side device.

[0164] or,

[0165] When the terminal determines that it needs to report the first indication information, and the measurement result of the terminal's reference signal meets the first condition, the terminal sends the first indication information to the first network-side device.

[0166] Therefore, when the terminal has available data or determines that it needs to report the first indication information, the terminal can determine whether the measurement result of its reference signal meets the first condition. If the first condition is met, the terminal will report the first indication information to the first network-side device. That is, the terminal only determines whether the measurement result of its reference signal meets the first condition when needed, thereby saving the terminal's power consumption.

[0167] Optionally, if the amount of the first data already stored in the terminal is greater than or equal to the fourth threshold, the terminal determines that it needs to report the first indication information.

[0168] As can be seen, in some embodiments, when the amount of the first data stored by the terminal is greater than or equal to the fourth threshold, and the measurement result of the terminal's reference signal meets the first condition, the terminal sends the first indication information to the first network-side device.

[0169] Optionally, the method further includes:

[0170] The terminal receives indication information of the first condition and first information sent by the first network-side device; wherein, the first information is used to determine whether the measurement result of the terminal's reference signal satisfies the first condition.

[0171] Therefore, it can be seen that the indication information of the first condition and the first information can be configured by the first network-side device.

[0172] In some embodiments, the configuration information reported by the first network-side device to the terminal includes indication information of the first condition and first information. The format of the configuration information can be an establishment or release format.

[0173] Optionally, the first condition is associated with a Radio Resource Management (RRM) measurement reporting configuration identifier (ReportConfigId). In this case, it can be understood that the RRM measurement reporting configuration includes at least one of the first, second, and third events mentioned above. Therefore, in some embodiments of this application, the terminal can use at least one of the first, second, and third events in the RRM measurement reporting configuration as a condition for determining whether to report the first indication information. In this way, the first network-side device can omit the step of separately configuring the first condition, thereby reducing signaling interaction.

[0174] Optionally, the first indication information sent by the terminal to the first network-side device is carried in at least one of the following:

[0175] The terminal's UE Assistance Information and Measurement Report.

[0176] In some embodiments, if the measurement result of the terminal's reference signal meets the first condition described above, the terminal sends first indication information to the first network-side device through at least one of UEAssistanceInformation and MeasurementReport.

[0177] Optionally, the method further includes:

[0178] The terminal sends a second indication message to the first network-side device, wherein the second indication message is used to indicate that the terminal supports sending the first indication message when the measurement result of the terminal's reference signal meets the first condition.

[0179] Therefore, it can be seen that the terminal can interact with the first network-side device to inform the first network-side device that it supports sending first indication information when the measurement results of the terminal meet the first condition, so that the first network-side device can configure the indication information and / or first information of the first condition for the terminal, thereby enabling the terminal to report the first indication information to the first network-side device when the first condition is met.

[0180] Optionally, the method further includes:

[0181] The terminal receives a first data request sent by the second network-side device, wherein the first data request is used to request the first data.

[0182] In some embodiments, the terminal receives a first data request sent by the second network-side device, and then the terminal sends the first data and the identification information of the first network-side device to the second network-side device.

[0183] Optionally, the first data request may include the identification information of the first network-side device.

[0184] The first data request carries the identification information of the first network-side device, which can indicate that the first data request requests data collected by the terminal at the instruction of the first network-side device.

[0185] Additionally, it should be noted that the identification information of network-side devices in this article can be the NR Cell Global Identifier (NCGI).

[0186] Optionally, the method further includes:

[0187] After the network-side device serving the terminal is changed to the second network-side device, the terminal sends the first indication information to the second network-side device.

[0188] Therefore, when the network-side device of the service terminal is changed to the second network-side device (for example, after the terminal performs cell handover), the terminal can report the first indication information to the second network-side device to inform the second network-side device that the first network-side device indicates that the data it collects is available.

[0189] In some embodiments, after the network-side device of the serving terminal is changed to the second network-side device, the terminal sends first indication information to the second network-side device; then, the terminal receives a first data request sent by the second network-side device, thereby causing the terminal to send first data and the identification information of the first network-side device to the second network-side device; subsequently, the second network-side device forwards the first data to the first network-side device. Thus, even if the network-side device of the serving terminal is changed to the second network-side device, the first network-side device can still obtain the data that the terminal was instructed to collect by the first network-side device.

[0190] Optionally, the first indication information sent by the terminal to the second network-side device is carried in a Radio Resource Control Reconfiguration Complete message (RRCReconfigurationComplete).

[0191] Optionally, the first indication information is associated with the identification information of the first network-side device.

[0192] In some embodiments, the association between the first indication information and the identification information of the first network-side device can be as follows: when the terminal reports the first indication information, it also reports the identification information of the first network-side device, wherein the first indication information and the identification information of the first network-side device are independent of each other; or, the first indication information includes the identification information of the first network-side device.

[0193] Optionally, the method further includes:

[0194] The terminal receives the collection configuration information sent by the first network-side device;

[0195] The terminal collects the first data according to the collection configuration information and stores the first data.

[0196] Therefore, it can be seen that the first network-side device can configure the terminal with collection configuration information, so that the terminal can collect data based on the collection configuration information, obtain the first data, and save it.

[0197] It is understandable that after the network-side device of the serving terminal is changed to the second network-side device, the second network-side device can also configure the collection configuration information for the terminal. However, after the network-side device of the serving terminal is changed to the second network-side device, if the second network-side device receives the first indication information sent by the terminal, it means that the data (i.e., the first data) collected by the terminal indicated by the first network-side device is available. In this case, the second network-side device can request the first data from the terminal and then configure the collection configuration information for it, so as to prevent the data collected by the terminal according to the collection configuration information configured by the second network-side device from overwriting the first data.

[0198] Optionally, the collection configuration information is used to indicate at least one of the following B-1 to B-3:

[0199] Item B-1: Data collection range; the data collection range can be indicated by the serving cell or a cell list;

[0200] Item B-2: Data Acquisition Type; Optionally, the data acquisition type includes at least one of the following: gNB-triggered data acquisition, OAM-triggered data acquisition. In some embodiments, the data acquisition type can be indicated implicitly, for example, by determining whether the data acquisition type is gNB-triggered data acquisition based on whether OAM-related information (e.g., OAM ID, IP address) exists in the acquisition configuration information; for example, if OAM-related information exists in the acquisition configuration information, the data acquisition type indicated by the acquisition configuration information is: OAM-triggered data acquisition; if OAM-related information does not exist in the acquisition configuration information, the data acquisition type indicated by the acquisition configuration information is: gNB-triggered data acquisition.

[0201] Item B-3: Whether to record the identification information of the first network-side device that sent the collection configuration information. For example, if item B-3 is a first value (e.g., true), it means that the identification information of the first network-side device that sent the collection configuration information needs to be recorded; or, if item B-3 is a second value (e.g., false), it means that the identification information of the first network-side device that sent the collection configuration information does not need to be recorded.

[0202] Optionally, the method further includes:

[0203] The terminal records the identification information of the first network-side device under at least one of the following conditions:

[0204] The cell corresponding to the data collection range indicated by the collection configuration information includes the cell corresponding to the first network-side device;

[0205] The first network-side device is a base station, and the data collection type indicated by the collection configuration information includes base station-triggered data collection;

[0206] The collection configuration information indicates the recording of the identification information of the first network-side device that sent the collection configuration information.

[0207] If the cell corresponding to the data collection range includes the cell corresponding to the first network-side device, it means that the first network-side device instructs the terminal to collect data. In this case, the identification information of the first network-side device can be recorded so as to record which data is collected by the terminal instructing the first network-side device.

[0208] If the data collection type includes base station-triggered data collection, it means that the terminal needs to execute a base station-triggered data collection process. In this case, the terminal can record the identification information of the first network-side device to record which data was instructed by the first network-side device to be collected by the terminal.

[0209] If the data collection configuration information configured by the first network-side device indicates that the terminal needs to record the identification information of the first network-side device, then the terminal needs to record the identification information of the first network-side device in order to record which data was collected by the terminal at the instruction of the first network-side device.

[0210] Referring to Figure 4, an embodiment of this application also provides a transmission method, which may include the following step 401:

[0211] Step 401: The first network-side device receives the first indication information sent by the terminal when the measurement result of the reference signal of the terminal meets the first condition.

[0212] Wherein, the first network-side device is a network-side device serving the terminal; the first indication information is used to indicate that the first data is available; here, the first data includes data collected by the terminal at the instruction of the first network-side device. It can be seen that, in some embodiments of this application, if the measurement result of the terminal's reference signal meets a first condition, the terminal can report the availability of the first data to the first network-side device.

[0213] It should be noted that the first indication information can be understood as a data availability indication; the data collected by the terminal by the first network-side device can be understood as: at least part of the data collected by the terminal by the first network-side device; the first network-side device is the network-side device of the current serving terminal, or it can also be understood as the network-side device corresponding to the source cell before the terminal performs cell handover.

[0214] In some embodiments, the first condition is used to indicate the condition that the measurement result of the reference signal is satisfied when the terminal is at the cell edge. Thus, the measurement result of the terminal's reference signal satisfying the first condition can be understood as the terminal being at the cell edge. In this case, the terminal sends a first indication message to the first network-side device to inform the first network-side device that the first data is available, so as to assist the first network-side device in requesting the first data. In this way, the first network-side device can obtain the first data before the terminal performs cell handover, thereby avoiding the situation where the network-side device corresponding to the source cell (i.e., the first network-side device) cannot obtain the data it instructed the terminal to collect after the terminal performs cell handover.

[0215] Alternatively, in some embodiments, the first condition can be understood as a more lenient condition than the cell handover condition, so that the terminal can trigger the reporting of the first indication information before triggering the measurement report for handover.

[0216] As can be seen from step 401 above, when the network-side device of the serving terminal is the first network-side device (e.g., before the network-side device of the serving terminal is changed, or when the network-side device of the serving terminal is not changed), if the measurement result of the terminal's reference signal meets the first condition, then the terminal can report first indication information to the first network-side device to inform the first network-side device that the first data collected by the terminal is available. Therefore, in the embodiments of this application, when the network-side device of the serving terminal is the first network-side device, a condition is added for the terminal to report the availability of data to the first network-side device currently serving it, to assist the first network-side device in requesting the first data collected by the terminal, so that the first network-side device can train the corresponding AI model based on the first data.

[0217] Optionally, the measurement results of the reference signal include the measurement results of the serving cell of the terminal and / or the measurement results of the neighboring cells of the terminal;

[0218] The first condition includes at least one of the following A-1 to A-3:

[0219] Item A-1: ​​First event, used to indicate that the measurement result of the serving cell of the terminal is less than or equal to a first threshold;

[0220] Item A-2: Second event, used to indicate that the difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to a second threshold;

[0221] Item A-3: Third event, used to indicate that the measurement result of the neighboring cell is greater than or equal to a third threshold.

[0222] It should be noted that the relevant explanations for items A-1 to A-3 here can be found in the previous text, and will not be repeated here.

[0223] Optionally, the method further includes:

[0224] The first network-side device sends the indication information of the first condition and the first information to the terminal;

[0225] The first information is used to determine whether the measurement result of the reference signal of the terminal meets the first condition.

[0226] Therefore, it can be seen that the indication information of the first condition and the first information can be configured by the first network-side device.

[0227] In some embodiments, the configuration information reported by the first network-side device to the terminal includes indication information of the first condition and first information. The format of the configuration information can be an establishment or release format.

[0228] Optionally, the first condition is associated with a Radio Resource Management (RRM) measurement reporting configuration identifier (ReportConfigId). In this case, it can be understood that the RRM measurement reporting configuration includes at least one of the aforementioned first event, second event, and third event. Therefore, in some embodiments of this application, the terminal can use at least one of the first event, second event, and third event in the RRM measurement reporting configuration as a condition for determining whether to report the first indication information. This way, the first network-side device can omit the step of separately configuring the first condition, thereby reducing signaling interaction. Optionally, the first information includes at least one of the following A-4 to A-12:

[0229] Item A-4: The measurement trigger threshold for the first event;

[0230] Item A-5: Hysteresis parameters of the first event;

[0231] Item A-6: Duration threshold of the first event;

[0232] Item A-7: The measurement trigger threshold for the second event;

[0233] Item A-8: Hysteresis parameters of the second event;

[0234] Item A-9: The duration threshold of the second event;

[0235] Item A-10: The measurement trigger threshold for the third event;

[0236] Item A-11: The hysteresis parameter of the third event;

[0237] Item A-12: The duration threshold of the third event.

[0238] It should be noted that the relevant explanations for items A-4 to A-12 here can be found in the previous text, and will not be repeated here.

[0239] Furthermore, the relevant explanations regarding satisfying the first event, the second event, and the third event can be found in the preceding text, and will not be repeated here.

[0240] Optionally, the first indication information is carried in at least one of the following:

[0241] The terminal's UE Assistance Information and Measurement Report.

[0242] In some embodiments, if the measurement result of the terminal's reference signal meets the first condition described above, the terminal sends first indication information to the first network-side device through at least one of UEAssistanceInformation and MeasurementReport.

[0243] Optionally, the method further includes:

[0244] The first network-side device receives a second indication message sent by the terminal, wherein the second indication message is used to indicate that the terminal supports sending the first indication message if the measurement result of the terminal's reference signal meets the first condition.

[0245] Therefore, it can be seen that the terminal can interact with the first network-side device to inform the first network-side device that it supports sending first indication information when the measurement results of the terminal meet the first condition, so that the first network-side device can configure the indication information and / or first information of the first condition for the terminal, thereby enabling the terminal to report the first indication information to the first network-side device when the first condition is met.

[0246] Optionally, the method further includes:

[0247] The first network-side device receives the first data sent by the second network-side device.

[0248] The first data sent from the second network-side device to the first network-side device is sent from the terminal to the second network-side device.

[0249] Therefore, the terminal can send the first data to the second network-side device, which then forwards it to the first network-side device. Thus, after the network-side device serving the terminal is changed to the second network-side device, the original first network-side device serving the terminal can also obtain the data (i.e., the first data) that it instructed the terminal to collect.

[0250] Optionally, the first indication information is associated with the identification information of the first network-side device.

[0251] In some embodiments, the association between the first indication information and the identification information of the first network-side device can be as follows: when the terminal reports the first indication information, it also reports the identification information of the first network-side device, wherein the first indication information and the identification information of the first network-side device are independent of each other; or, the first indication information includes the identification information of the first network-side device.

[0252] Optionally, the method further includes:

[0253] The first network-side device sends data collection configuration information to the terminal, which instructs the terminal to perform data collection.

[0254] Therefore, it can be seen that the first network-side device can configure the terminal with collection configuration information, so that the terminal can collect data based on the collection configuration information, obtain the first data, and save it.

[0255] Optionally, the collection configuration information is used to indicate at least one of the following B-1 to B-3:

[0256] Item B-1: Data Collection Scope;

[0257] Item B-2: Data Collection Type;

[0258] Item B-3: Whether to record the identification information of the first network-side device that sent the collection configuration information.

[0259] It should be noted that the relevant explanations for items B-1 to B-3 here can be found in the previous text, and will not be repeated here.

[0260] Referring to Figure 5, an embodiment of this application also provides a transmission method, which may include the following step 501:

[0261] Step 501: After the network-side device of the service terminal is changed to the second network-side device, the second network-side device receives the first data sent by the terminal and the identification information of the first network-side device.

[0262] The first data includes data collected by the terminal at the instruction of the first network-side device.

[0263] In some embodiments of this application, after the network-side device of the serving terminal is changed to a second network-side device, the terminal can report to the second network-side device the data collected by the terminal as instructed by the first network-side device and the identification information of the first network-side device. It can be understood that the data collected by the terminal as instructed by the first network-side device can also be interpreted as at least a portion of the data collected by the terminal as instructed by the first network-side device.

[0264] In addition, after the terminal sends the first data and the identification information of the first network-side device to the second network-side device, the second network-side device can forward the first data to the first network-side device.

[0265] In addition, it should be noted that the second network-side device can be understood as the network-side device corresponding to the target cell after the terminal performs cell handover.

[0266] Optionally, the first data and the identification information of the first network-side device can be sent independently or together. For example, when the terminal sends the first data to the second network-side device, the identification information of the first network-side device is carried in the first data.

[0267] As can be seen from step 501 above, in this embodiment, the second network-side device can receive first data sent by the terminal and the identification information of the first network-side device. The first data includes data collected by the terminal at the instruction of the first network-side device. Therefore, in this embodiment, after the network-side device of the serving terminal is changed to the second network-side device, the terminal can report the first data collected by the terminal at the instruction of the first network-side device and the identification information of the first network-side device to the second network-side device. Thus, after receiving the first data, the second network-side device can identify the network-side device that instructed the collection of the first data, thereby assisting the second network-side device in providing the first data to the first network-side device. This allows the first network-side device to train the corresponding AI model based on the first data.

[0268] Optionally, the method further includes:

[0269] The second network-side device sends a first data request to the terminal, wherein the first data request is used to request the first data.

[0270] In some embodiments, the terminal receives a first data request sent by the second network-side device, and then the terminal sends the first data and the identification information of the first network-side device to the second network-side device.

[0271] Optionally, the first data request may include the identification information of the first network-side device.

[0272] The first data request carries the identification information of the first network-side device, which can indicate that the first data request requests data collected by the terminal at the instruction of the first network-side device.

[0273] Optionally, the method further includes:

[0274] The second network-side device receives a second data request sent by the first network-side device, wherein the second data request is used to request the first data.

[0275] It should be noted that although both the first data request and the second data request are used to indicate a request for the first data, the first data request is sent from the second network-side device to the terminal, while the second data request is sent from the first network-side device to the second network-side device, and their formats or forms may be different.

[0276] Therefore, the first network-side device can request the first data from the second network-side device, so that the second network-side device can request the first data from the terminal, and then the second network-side device can forward the first data sent by the terminal to the first network-side device.

[0277] Optionally, the method further includes:

[0278] After the network-side device serving the terminal is changed to the second network-side device, the second network-side device receives the first indication information sent by the terminal;

[0279] The first indication information is used to indicate that the first data is available.

[0280] Therefore, when the network-side device of the service terminal is changed to the second network-side device (for example, after the terminal performs cell handover), the terminal can report the first indication information to the second network-side device to inform the second network-side device that the first network-side device indicates that the data it collects is available.

[0281] In some embodiments, after the network-side device of the serving terminal is changed to the second network-side device, the terminal sends first instruction information to the second network-side device. The first network-side device can send the aforementioned second data request to the second network-side device, thereby causing the second network-side device to send the first data request to the terminal, which in turn causes the terminal to send first data and the identification information of the first network-side device to the second network-side device. This then causes the second network-side device to forward the first data to the first network-side device. Thus, even if the network-side device of the serving terminal is changed to the second network-side device, the first network-side device can still obtain the data that the terminal was instructed to collect by the first network-side device.

[0282] Optionally, the first indication information is carried in a radio resource control reconfiguration completion message.

[0283] Optionally, the first indication information is associated with the identification information of the first network-side device.

[0284] In some embodiments, the association between the first indication information and the identification information of the first network-side device can be as follows: when the terminal reports the first indication information, it also reports the identification information of the first network-side device, wherein the first indication information and the identification information of the first network-side device are independent of each other; or, the first indication information includes the identification information of the first network-side device.

[0285] Optionally, the method further includes:

[0286] The second network-side device sends the first data to the first network-side device based on the identification information of the first network-side device.

[0287] Therefore, after receiving the first data and the identification information of the first network side device, the second network side device can send the first data to the first network side device according to the identification information of the first network side device, so that the first network side device can train the corresponding AI model based on the first data.

[0288] To facilitate understanding of the transmission method of the embodiments of this application, the following two specific implementations of the transmission method of the embodiments of this application will now be introduced.

[0289] Implementation Method 1: As shown in Figure 6, it includes the following steps 1 to 3:

[0290] Step 1: Capability interaction, i.e., the terminal reports to the first network-side device: the terminal supports the function of reporting data availability indication based on the first condition;

[0291] Step 2: If the first network-side device has a data collection requirement, it sends a data collection request to the terminal and sends the data availability indication reporting configuration information.

[0292] The reported configuration information can be in the format of creation or release;

[0293] In addition, the reported configuration information includes indication information of the first condition for reporting data availability indication and measurement results of the reference signal of the terminal to determine whether the first condition is met; the measurement results of the reference signal include the measurement results of the serving cell of the terminal and / or the measurement results of the neighboring cells of the terminal;

[0294] The first condition includes at least one of the following:

[0295] The first event is used to indicate that the measurement result of the serving cell of the terminal is less than or equal to a first threshold.

[0296] The second event is used to indicate that the difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the second threshold.

[0313] The measurement result of the serving cell is less than or equal to the sum of the measurement trigger threshold of the first event and the hysteresis parameter of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event.

[0314] The measurement result of the serving cell is less than or equal to the measurement trigger threshold of the first event, and the measurement result of the serving cell is less than or equal to the sum of the measurement trigger threshold of the first event and the hysteresis parameter of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event.

[0315] Optionally, the second event is satisfied if at least one of the following conditions is met:

[0316] The difference between the measurement results of the neighboring cell and the measurement results of the serving cell is greater than or equal to the measurement trigger threshold of the second event;

[0317] The difference between the measurement results of the neighboring cell and the measurement results of the serving cell is greater than or equal to the sum of the measurement trigger threshold of the second event and the hysteresis parameter of the second event;

[0318] Alternatively, the second event is satisfied under one of the following conditions:

[0319] The difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the measurement trigger threshold of the second event, and the duration of the second event is greater than or equal to the duration threshold of the second event.

[0320] The difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the sum of the measurement trigger threshold of the second event and the hysteresis parameter of the second event, and the duration of the second event is greater than or equal to the duration threshold of the second event.

[0321] The difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the measurement trigger threshold of the second event, and the difference between the measurement result of the neighboring cell and the measurement result of the serving cell is greater than or equal to the sum of the measurement trigger threshold of the second event and the hysteresis parameter of the second event, and the duration of the second event is greater than or equal to the duration threshold of the second event.

[0322] Optionally, the third event is satisfied if at least one of the following conditions is met:

[0323] The measurement result of the neighboring cell is greater than or equal to the measurement trigger threshold of the third event;

[0324] The measurement result of the neighboring cell is greater than or equal to the sum of the measurement trigger threshold of the third event and the hysteresis parameter of the third event;

[0325] Alternatively, the third event is satisfied under one of the following conditions:

[0326] The measurement result of the neighboring cell is greater than or equal to the measurement trigger threshold of the third event, and the duration of the third event is greater than or equal to the duration threshold of the third event;

[0327] The measurement result of the neighboring cell is greater than or equal to the sum of the measurement trigger threshold of the third event and the hysteresis parameter of the third event, and the duration of the third event is greater than or equal to the duration threshold of the third event.

[0328] The measurement result of the neighboring cell is greater than or equal to the measurement trigger threshold of the third event, and the measurement result of the neighboring cell is greater than or equal to the sum of the measurement trigger threshold of the third event and the hysteresis parameter of the third event, and the duration of the third event is greater than or equal to the duration threshold of the third event.

[0329] Step 3: If there is available data on the terminal, or if it is determined that a data availability indication needs to be reported, determine whether the first condition above is met. If it is met, report the data availability indication.

[0330] Optionally, the terminal needs to report a data availability indication, which is determined based on a specific threshold, such as the amount of data collected by the terminal being greater than or equal to a fourth threshold, as indicated by the first network-side device.

[0331] Optionally, the first condition mentioned above can be directly associated with an RRM measurement reporting configuration ID, namely ReportConfigId.

[0332] Optionally, the data availability indication can be sent via UE Assistance Information; or via Measurement Report.

[0333] In addition, after receiving the data availability indication, the first network-side device can consider the data availability indication in the data collection configuration and data acquisition. It can request the terminal to report the data collected by the terminal as instructed by the first network-side device. If the request can be a UE Information Request, the terminal will report the data it collected through the UE Information Response.

[0334] It should be noted that in Implementation Method 1, when the terminal moves to the cell edge, a data availability indication can be triggered to assist the network in requesting data recording, that is, the terminal can report the data recording before handover.

[0335] Implementation Method Two: As shown in Figure 7, it includes the following steps 1 to 8:

[0336] Step 1: The first network-side device has a data collection requirement and sends the collection configuration information to the terminal;

[0337] The configuration information collected is used to indicate at least one of the following:

[0338] Data collection range; the data collection range can be indicated by the serving cell or a cell list;

[0339] Data acquisition type; optionally, the data acquisition type includes at least one of the following: gNB-triggered data acquisition, OAM-triggered data acquisition; in some embodiments, the data acquisition type indication can be an implicit indication, for example, determining whether the data acquisition type is gNB-triggered data acquisition based on whether OAM-related information (such as OAM ID, IP address) exists in the acquisition configuration information; for example, if OAM-related information exists in the acquisition configuration information, the data acquisition type indicated by the acquisition configuration information is: OAM-triggered data acquisition; if OAM-related information does not exist in the acquisition configuration information, the data acquisition type indicated by the acquisition configuration information is: gNB-triggered data acquisition;

[0340] Whether to record the identification information of the first network-side device that sends the collection configuration information; for example, when the information field of the collection configuration information is used to indicate whether to record the identification information of the first network-side device that sends the collection configuration information, if it is a first value (e.g., true), it means that the identification information of the first network-side device that sends the collection configuration information needs to be recorded; if the information field is a second value (e.g., false), it means that the identification information of the first network-side device that sends the collection configuration information does not need to be recorded.

[0341] Step 2: The terminal records the identification information (e.g., NCGI) of the first network-side device that sent the collection configuration information under at least one of the following conditions:

[0342] The cell corresponding to the data collection range indicated by the collection configuration information includes the cell corresponding to the first network-side device;

[0343] The first network-side device is a base station, and the data collection type indicated by the collection configuration information includes base station-triggered data collection;

[0344] The collection configuration information indicates the recording of the identification information of the first network-side device that sent the collection configuration information.

[0345] Step 3: The terminal collects data according to the data collection configuration information and records the first data collected;

[0346] Step 4: Change the network-side device of the service terminal to a second network-side device;

[0347] Step 5: The terminal sends a data availability indication to the second network-side device. This data can be used to indicate that the data (i.e., the first data) collected by the terminal is available, as indicated by the first network-side device.

[0348] Optionally, the data may be used to indicate the identification information of the associated first network-side device;

[0349] Optionally, the data availability indication can be sent to the second network-side device via an RRCReconfigurationComplete message.

[0350] It should be noted that if the terminal can only save the record data of one cell, that is, it cannot save the list, then the data availability indicator in step 5 can be used as a reference for the second network-side device to avoid sending new collection configuration information and overwriting the original record data.

[0351] In other words, after the network-side device of the serving terminal is changed to the second network-side device, the second network-side device can also configure new collection configuration information for the terminal. However, after the network-side device of the serving terminal is changed to the second network-side device, if the second network-side device receives a data availability indication sent by the terminal, it means that the data (i.e., the first data) collected by the terminal indicated by the first network-side device is available. In this case, the second network-side device can request the first data from the terminal and then configure new collection configuration information for it, so as to prevent the data collected by the terminal according to the collection configuration information configured by the second network-side device from overwriting the first data.

[0352] Step 6: The second network-side device sends a first data request to the terminal;

[0353] Optionally, the first data request includes the identification information of the first network-side device, used to request the first network-side device to instruct the terminal to collect data (i.e., the first data) (or it can also be understood as: the data collected by the terminal when the network-side device of the service terminal is the first network-side device).

[0354] Optionally, before step 6, the second network-side device receives a second data request sent by the first network-side device to trigger the second network-side device to send a first data request to the terminal.

[0355] Step 7: The terminal sends the first data and the identification information of the first network-side device to the second network-side device;

[0356] Step 8: Data relay, that is, the second network-side device forwards the first data to the first network-side device according to the identification information of the first network-side device.

[0357] It should be noted that the above-described implementation method one aims to ensure that the terminal can report the collected data to the network-side device that instructed it to perform the data collection. However, it is still possible that the network-side device of the serving terminal may be changed before the terminal completes the data reporting. To solve this problem, in implementation method two: the terminal records the node that configures the data collection information, and when reporting the collected data, it associates the information of this node. If the network-side device of the serving terminal is changed, the modified second network-side device can forward the reported data to this node based on the node information.

[0358] As can be seen, in this embodiment, on the one hand, the terminal can promptly report a data availability indication before switching, enabling the first network-side device of the current serving terminal to request and obtain data as quickly as possible; on the other hand, after the network-side device of the serving terminal is changed to the second network-side device, it is not necessary to discard the data collected by the terminal at the instruction of the first network-side device and report the data to the first network-side device. Therefore, the embodiments of this application can improve the overall efficiency of network-side data collection.

[0359] The transmission method provided in this application can be executed by a transmission device. This application uses an example of a transmission device executing the transmission method to illustrate the transmission device provided in this application.

[0360] This application provides a transmission device. As an example, the transmission device may be a communication device or a component within a communication device, such as a chip. The communication device may be a terminal, a network-side device, or a server, etc. Exemplarily, the terminal may include, but is not limited to, the type of terminal 11 listed above, and the network-side device may include, but is not limited to, the type of network-side device 12 listed above. This application does not impose specific limitations.

[0361] The transmission device includes a receiving module, a transmitting module, and a processing module. These modules can be implemented in software or hardware. When implemented in hardware, the processing module can be implemented by a processor. For example, the processor can include general-purpose processors, special-purpose processors, etc., such as central processing units (CPUs), microprocessors, digital signal processors (DSPs), artificial intelligence (AI) processors, graphics processing units (GPUs), application-specific integrated circuits (ASICs), network processors (NPs), field-programmable gate arrays (FPGAs), or other programmable logic devices, gate circuits, transistors, discrete hardware components, etc. The receiving and transmitting modules can be implemented by a communication interface, which can include one or more of the following: transceivers, pins, circuits, buses, radio frequency units, etc.
