Description

Data collection methods, devices, communication equipment, storage media, and software products

[0001] This application claims priority to Chinese Patent Application No. 2025103840907, filed on March 28, 2025, entitled “Data Collection Method, Apparatus, Communication Equipment, Storage Medium and Program Product”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of mobile communication technology, and in particular to a data collection method, apparatus, communication device, storage medium, and program product. Background Technology

[0003] With the development of AI (Artificial Intelligence) / ML (Machine Learning) technologies, scenarios have emerged where AI / ML models are deployed on the network side, and beam management is implemented based on these models. Training the AI / ML functions / models on the network side requires data collection from the terminal. The measurement data reported by the terminal mainly includes: - The terminal receiving measurement configurations sent from the network side; - The terminal performing measurements according to the network side's measurement configurations and recording the measurement results in a buffer; - The terminal reporting measurement reports according to the network side's measurement configurations.

[0004] In related technologies, when the Radio Resource Control (RRC) state changes, such as switching from the RRC-Connected state to the RRC-Inactive state or the RRC-Idle state, the data previously measured and / or recorded by the terminal will no longer be able to be reported to the network side.

[0005] However, the terminal consumes resources (such as memory and power) when collecting this data, and it would be a waste of resources if the terminal discards this data when the radio resource control state changes. Summary of the Invention

[0100] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0101] The data collection method provided in this application includes a terminal and a network-side device. In this application, the terminal is also referred to as UE-side (User Equipment-side) and the network-side device is also referred to as NW-side (Network-side).

[0102] The terminal can be a wireless terminal, which can be a device that provides voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a Radio Access Network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the RAN. The wireless terminal can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, access terminal, user terminal, user agent, user device, or user equipment, without limitation herein.

[0103] Among them, the network-side equipment can be a base station (BTS) in Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA), a base station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB or eNodeB) in LTE, a relay station or access point, or a base station in a 5G network, etc., and is not limited here.

[0104] In related technologies, when the terminal's Radio Resource Control (RRC) state changes, such as switching from RRC-Connected to RRC-Inactive or RRC-Idle, previously measured and / or recorded data can no longer be reported to the network. Considering the resources consumed by the terminal when collecting this data (such as memory and power), discarding this data when the RRC state changes is a waste of resources for the terminal. If the terminal wants to report its measured and / or recorded data to the base station, there are two possible scenarios: 1) Reporting the data to the network before the RRC state transition; 2) When transitioning from RRC-Connected to RRC-Inactive / RRC-Idle, the network side controls the terminal to retain the measured and / or recorded data. When the terminal re-establishes a connection with the base station (i.e., transitioning from RRC-Inactive / RRC-Idle to RRC-Connected), the terminal reports the retained measured and / or recorded data to the base station. Scenario 1) is relatively simple, while Scenario 2) involves terminal mobility. Specifically, the base station (target base station) where the terminal re-establishes a connection may not be the same as the initial base station (source base station). Considering that the source base station's measurement configuration is designed based on its network conditions and may not be applicable to the target base station, and the terminal is unaware of whether the target base station supports certain AI / ML functions / models, the data measured by the terminal within the source base station's coverage area may not be applicable to the target base station. Therefore, in mobile scenarios, whether the terminal needs to retain the measured and / or recorded data, and how to process it after retention, requires further discussion.

[0105] In summary, this application proposes a data reporting scheme for terminals in the two scenarios mentioned above. It innovatively proposes a data collection method for the network-side model across radio resource control (RRC) states. This method allows the terminal to control whether to report measured and / or recorded data before entering the RRC_Inactive / Idle state, based on network-side information, during the transition between RRC states. If it is determined that no reporting will occur before entering the RRC_Inactive / Idle state, the already measured and / or recorded data can be retained or released, and the reporting of the retained measured and / or recorded data in subsequent connected states can be controlled, thereby avoiding or reducing the waste of terminal resources.

[0106] It should be noted that the beneficial effects or technical problems solved by the embodiments of this application are not limited to this one, but may also be other implicit or related problems. For details, please refer to the description of the embodiments below.

[0107] Before introducing the specific embodiments of this application, the technical terms involved in this application will be explained:

[0108] Radio Resource Control (RRC) is a key protocol layer in the wireless communication protocol stack. RRC plays a crucial role in mobile communication systems, serving as the core protocol of the control plane between the UE (User Equipment, such as a mobile phone) and the network (such as a base station, eNB / gNB). Through RRC, the network can efficiently manage the UE's connectivity, mobility, and quality of service.

[0109] The RRC protocol defines two main states for the UE, used to manage the UE's power consumption and resource usage:

[0110] (1) RRC-Connected, Radio Resource Control connected state / mode; In this state, the UE has established an RRC connection and can transmit data with the network. The network allocates dedicated resources to the UE and manages its mobility (such as handover). The UE has higher power consumption and is suitable for active users.

[0111] (2) RRC-Inactive, Radio Resource Control inactive state / mode (also known as RRC-Idle in some scenarios). In this state, the UE does not establish an RRC connection, but the UE can perform cell selection, cell reselection, and receive system information broadcasts. The UE has low power consumption and is suitable for inactive users.

[0112] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0113] In one embodiment, as shown in Figure 1, a data collection method is provided for a terminal transitioning from a Radio Resource Control (RRC) idle state or an RRC inactive state to a RRC connected state. The method is illustrated using a terminal as an example and includes the following steps:

[0114] S101, the terminal enters the radio resource control connected state from the radio resource control idle state or the radio resource control inactive state, and the terminal sends the first message to the network side device.

[0115] The first message includes first indication information, which is used to indicate to the network-side device whether the terminal measurement and / or recorded data is available. The terminal measurement and / or recorded data may be data used for AI / ML models deployed on the network side. The terminal measurement and / or recorded data includes three scenarios: terminal measurement data, terminal recorded data, and a combination of both.

[0116] In this context, the network-side device can be understood as an access network device, such as a base station. The terminal sending a first message to the network-side device can be a message sent from the terminal to the base station; this application embodiment does not limit the type of this message. Furthermore, this application does not limit the position and symbol of the first indication information in this first message, as long as the network-side device receives the first message sent by the terminal and can parse the first indication information therein to determine whether the measurement and / or recording data of the terminal sending the first message is available. As an example, if the indication indicates that the terminal's measurement and / or recording data is available, the first indication information can be represented as 1; if the indication indicates that the terminal's measurement and / or recording data is not available, the first indication information can be represented as 0.

[0117] S102, in response to a message from the network-side device, processes the terminal's measurement and / or recording data.

[0118] Among them, the messages from the network-side equipment can be messages sent by the base station to the terminal. This application embodiment does not limit the type of the message, which can be an RRC message, a request message, or a response message sent by the base station to the terminal.

[0119] Based on the above embodiments, when a terminal switches from the RRC_Inactive / Idle state to the RRC-Connected state, the terminal can report an indication to the currently connected network-side device to indicate whether the data measured and / or recorded by the terminal is available. Then, based on the message sent by the network-side device, the terminal can perform processes such as reporting, retaining, deleting, or releasing its measured and / or recorded data. Thus, during the transition of the radio resource control state, the terminal can indicate to the network side whether its measured and / or recorded data is available, and then process the measured and / or recorded data based on the message from the network-side device, thereby reducing the waste of terminal resources.

[0120] In this embodiment, the terminal sends a first message to the network-side device, and processes the terminal's measurement and / or recording data in response to the message from the network-side device; the two are related as AND and OR. For example, when the terminal enters the connected state from the Radio Resource Control (RRC) state or the RRC inactive state, it can receive and respond to the message from the network-side device and process the terminal's measurement and / or recording data, without necessarily sending the first message to the network-side device first. As another example, when the terminal enters the connected state from the RRC state or the RRC inactive state, it can send the first message to the network-side device and receive the message from the network side, but does not immediately perform processing on the terminal's measurement and / or recording data.

[0121] In one embodiment, the aforementioned processing of measurement and / or recorded data in response to a message from the network-side device may specifically include: in response to a second message from the network-side device, retaining or not retaining the measurement and / or recorded data.

[0122] Not retaining terminal measurement and / or recording data is the opposite of retaining terminal measurement and / or recording data. It can be understood as deleting terminal measurement and / or recording data, or releasing terminal measurement and / or recording data, and may also include releasing measurement configuration information related to the data.

[0123] Specifically, after sending the first message to the network-side device, the terminal may include: receiving an information request sent by the network-side device, and reporting measurement and / or recorded data to the network-side device. When reporting measurement and / or recorded data, the terminal may also report one or more of the following: the time of measurement and / or recording, the terminal's location information at the time of measurement and / or recording, the AI / ML function information applicable to the measurement and / or recording data, and the AI / ML model information applicable to the measurement and / or recording data. Based on these one or more relevant information items, the network-side device can appropriately use the measurement and / or recorded data after receiving it from the terminal.

[0124] In other cases, after the terminal sends the first message to the network-side device, the message may further include: the terminal responding to a second message sent by the network-side device by retaining the measurement and / or recording data, or the terminal not retaining the measurement and / or recording data; wherein the second message contains second indication information, which is used to instruct the terminal to retain or not retain the measurement and / or recording data.

[0125] In some specific implementations, the terminal can perform different data processing based on different second messages sent by the network-side device. For example, the terminal can report the measured and / or recorded data to the network-side device based on the information request sent by the network-side device; or, based on the indication information carried in the message sent by the network-side device to indicate that the data should be retained, the terminal can retain the measured and / or recorded data; or, based on the indication information carried in the message sent by the network-side device to indicate that the data should not be retained, the terminal can release or delete the measured and / or recorded data.

[0126] This application embodiment does not limit the type of the second message sent by the network-side device to the terminal, nor does it limit the position and representation of the second indication information in the second message. As long as the terminal receives the second message, it can know whether the network-side device wants the terminal to retain the data or not.

[0127] When a terminal is in a mobile state, during the transition of radio resource control state, it may switch network-side devices, that is, switch from connecting to a first network-side device to connecting to a second network-side device. In order to distinguish between the different situations where network-side device switching occurs, in the following embodiments of this application, the first network-side device and the second network-side device are used to represent the network-side devices before and after the switch, respectively.

[0128] Correspondingly, in some embodiments, the data collection method of this application further includes: when a terminal switch occurs, the terminal switches from a first network-side device to a second network-side device.

[0129] When a terminal switches from a first network-side device to a second network-side device, the aforementioned sending of the first message to the network-side device includes: the terminal entering a radio resource control (RRC) connection state with the second network-side device from a RRC idle state or a RRC inactive state, and the terminal sending the first message to the second network-side device; wherein, the first message includes the first indication information, and if the first indication information indicates that the terminal's measurement and / or recording data is available, the first message also includes information associated with the terminal's measurement and / or recording data, so that the second network-side device can determine whether it needs to obtain the terminal's measurement and / or recording data.

[0130] In other embodiments, the information associated with the terminal measurement and / or recording data can also be sent to the second network-side device through other messages besides the first message. That is, the information associated with the terminal measurement and / or recording data can be included in the first message and sent together with the first indication information, or it can be sent through other messages independent of the first message.

[0131] In some exemplary embodiments, the information associated with the measurement and / or recording data sent by the terminal to the second network-side device may include at least one of the following: the time of measurement and / or recording data; the latency information of the measurement and / or recording data reporting; the location information of the terminal when measuring and / or recording data; the measurement configuration information of the first network-side device when measuring and / or recording data; the AI / ML function information applicable to the measurement and / or recording data; and the AI / ML model information (e.g., model ID) applicable to the measurement and / or recording data.

[0132] Based on the information associated with the measurement and / or recording data reported by the terminal, the second network-side device can effectively determine whether the terminal's measurement and / or recording data is applicable to its own network configuration or model configuration, and thus determine whether it is necessary to obtain the terminal's measurement and / or recording data, avoiding the waste of resources caused by obtaining data that is not applicable to itself.

[0133] In some embodiments, after the terminal sends the first message to the second network-side device, it further includes: receiving an information request sent by the second network-side device and reporting measurement and / or recording data to the second network-side device.

[0134] In this embodiment, the type of information request sent by the second network-side device is not limited. As long as the terminal receives the information request, it can trigger the process of reporting data to the second network-side device. Similarly, the form in which the terminal reports measurement and / or recorded data is not limited, as long as the terminal can send the measurement and / or recorded data to the second network-side device.

[0135] Further, after the terminal sends the first message to the second network-side device, the method further includes: in response to a second message sent by the second network-side device, the terminal chooses to retain the measurement and / or recording data, or not retain the measurement and / or recording data. The second message contains second indication information, which is used to indicate to the terminal that the measurement and / or recording data is not applicable to the second network-side device, or to indicate to the terminal whether to retain or not retain the measurement and / or recording data.

[0136] Based on the information associated with the measurement and / or recorded data reported by the terminal, if the second network-side device determines that the terminal's measurement and / or recorded data is suitable for its own network configuration or model configuration, it can send an information request to the terminal to request the acquisition of the terminal's measurement and / or recorded data. Conversely, if the second network-side device determines that the terminal's measurement and / or recorded data is not suitable for its own network configuration or model configuration, it can send a corresponding message to the terminal instructing it not to need the data and allowing the terminal to decide whether to retain it; alternatively, the second network-side device can also instruct the terminal to retain or not retain the data.

[0137] In one embodiment, as shown in Figure 2, for situations where the terminal needs to transition from the Radio Resource Control (RRC) connected state to the RRC idle state or the RRC inactive state, another data collection method is provided. The method is still applied to a terminal as an example for illustration, and includes the following steps:

[0138] S201, before the terminal enters the radio resource control idle state or the radio resource control inactive state from the radio resource control connected state, it sends a first message to the network-side device.

[0139] The first message includes a first indication information, which is used to indicate to the network-side device whether the terminal's measurement and / or recording data is available.

[0140] The first message and the first indication information in this embodiment may be the same as those in the previous embodiments, or they may differ from those in the previous embodiments. In one embodiment, before the terminal enters the Radio Resource Control (RRC) idle state or the RRC inactive state from the RRC connected state, the first message sent to the network-side device may be a response message to other messages from the network-side device. For example, if the network-side device determines that the terminal needs to enter the RRC idle state or the RRC inactive state later, the network-side device first sends a message to the terminal to indicate the current decision of the network-side device. Based on this message, the terminal returns a response message to the network-side device as the first message, and the first indication information may be carried in the response message.

[0141] S202, receive the message from the network-side device and process the measurement and / or recording data.

[0142] In one feasible implementation, step S202 specifically includes, before the terminal enters the radio resource control idle state or the radio resource control inactive state from the radio resource control connected state, receiving a message from the network-side device and responding to the message from the network-side device to process the measurement and / or recording data, including reporting the measurement and / or recording data, retaining the measurement and / or recording data, or deleting or releasing the measurement and / or recording data.

[0143] Specifically, for example: before the terminal transitions from a connected state to a disconnected state or an inactive state, it reports measurement and / or recording data to the network-side device in response to an information request sent by the network-side device. Alternatively, for example: before the terminal transitions from a connected state to a disconnected state or an inactive state, it responds to a second message from the network-side device to retain or not retain the measurement and / or recording data; the second message contains second indication information, which instructs the terminal to retain or not retain the measurement and / or recording data.

[0144] In another feasible implementation, step S202 specifically includes: before the terminal enters the Radio Resource Control (RRC) idle state or the RRC inactive state from the RRC connected state, it receives a message from the network-side device. If the message is an information request, the terminal promptly reports measurement and / or recording data before entering the RRC idle state or the RRC inactive state. If the received message from the network-side device is not an information request, the terminal can save the message and, after entering the RRC idle state or the RRC inactive state from the RRC connected state, respond to the message from the network-side device to process the measurement and / or recording data, including retaining the measurement and / or recording data, or deleting or releasing the measurement and / or recording data.

[0145] Specifically, for example: before the terminal transitions from the Radio Resource Control (RRC) connected state to the RRC idle state or the RRC inactive state, it receives an information request sent by the network-side device and reports measurement and / or recording data to the network-side device. Alternatively, for example: before the terminal transitions from the RRC connected state to the RRC idle state or the RRC inactive state, it receives a second message from the network-side device. This second message contains second indication information, which instructs the terminal to retain or not retain the measurement and / or recording data. Then, when the terminal transitions from the RRC connected state to the RRC idle state or the RRC inactive state, the process of retaining or not retaining the measurement and / or recording data is executed.

[0146] Based on the two feasible implementation methods described above, when a terminal needs to transition from the Radio Resource Control (RRC) connected state to the RRC idle state or the RRC inactive state, it can perform corresponding data processing (reporting data, retaining or not retaining data) based on the information request or second message from the network-side device before entering the RRC idle state or the RRC inactive state; alternatively, it can report data before entering the RRC idle state or the RRC inactive state, and retain the measurement and / or recording data, or not retain the measurement and / or recording data, when entering the RRC idle state or the RRC inactive state.

[0147] In this embodiment, the terminal sends a first message to the network-side device and receives a message from the network-side device to process the terminal's measured and / or recorded data; the two are related as AND and OR. For example, before the terminal enters the Radio Resource Control (RRC) idle state or the RRC inactive state from the RRC connected state, it can receive and respond to a message from the network-side device to process the terminal's measured and / or recorded data, without necessarily sending a first message to the network-side device first.

[0148] In some embodiments, sending the first message to the network-side device by the terminal includes: the terminal receiving a third message sent by the network-side device; the third message includes third indication information, which is used to indicate to the terminal that the network-side device has determined that the terminal needs to enter the radio resource control inactive / idle state.

[0149] After receiving the third message, the terminal determines whether the measurement and / or recording data is available and sends the first message to the network-side device.

[0150] The methods for determining whether the data that the terminal has measured and / or recorded is available may include:

[0151] The terminal's battery level is not less than a preset battery threshold.

[0152] The storage status of the terminal is not less than a preset storage threshold;

[0153] The wireless access layer cache state of the terminal is not less than a preset cache threshold.

[0154] The amount of data measured and / or recorded is not less than a preset data amount threshold;

[0155] If one or more of the above conditions are met (the conditions to be met can be configured based on the specific scenario), it is determined that the data that the terminal has measured and / or recorded is available; otherwise, it is determined that the data that the terminal has measured and / or recorded is not available.

[0156] In one embodiment, a data collection method is also provided, applied to a terminal, the data collection method comprising: the terminal entering a Radio Resource Control (RRC) idle state or a RRC inactive state from a RRC connected state, and retaining or not retaining measurement and / or recording data based on a message from a network-side device; wherein the message from the network-side device includes indication information, the indication information being used to instruct the terminal to retain or not retain the measurement and / or recording data.

[0157] It is understood that the message from the network-side device may be the same as or different from the second message in the aforementioned embodiments. The indication information contained in the message from the network-side device may be the same as or different from the second indication information in the aforementioned embodiments, and it needs to be used to instruct the terminal to retain or not retain its measurement and / or recording data.

[0158] In some embodiments, before the terminal transitions from the Radio Resource Control (RRC) connected state to the RRC idle state or the RRC inactive state, the terminal may also report its measurement and / or recording data to the network side. The implementation methods for the terminal to report its measurement and / or recording data are the same as those described in the foregoing embodiments and will not be repeated here.

[0159] Through the above embodiments, when the terminal enters the radio resource control idle state or the radio resource control inactive state from the radio resource control connected state, it can retain or not retain the measurement and / or recorded data based on the network side messages, so as to avoid the terminal deleting or releasing data without authorization, which would cause waste of terminal resources.

[0160] In one embodiment, Figure 3 provides a signaling interaction flowchart between the terminal and the base station when the terminal reports measured and / or recorded data to the base station before entering the RRC_Inactive state. This scenario, in which the terminal reports measured and / or recorded data to the network-side device before entering the RRC_Inactive state, is referred to as Scenario 1 in subsequent embodiments. Furthermore, the RRC_Inactive state in Scenario 1 can also be replaced by the RRC_Idle state.

[0161] Referring to Figure 3, the main process steps of Scenario 1 are described as follows:

[0162] Step 1: The base station determines that the terminal needs to enter the RRC_Inactive state.

[0163] Step 2: The base station sends an indication message to the terminal, indicating that the base station has determined that the terminal needs to enter the RRC_Inactive state.

[0164] The base station can send this indication information to the terminal through the aforementioned third message to inform the terminal that the base station has determined that it needs to enter the RRC_Inactive state.

[0165] Step 3: The terminal determines whether the measured and / or recorded data is available based on its internal conditions (such as battery status, storage status, cache status) and / or the size of the collected data.

[0166] As an example, when the terminal's battery level is not less than a set threshold (i.e., when the terminal's battery level is sufficient to support the completion of data measurement and / or recording and reporting), the data measured and / or recorded by the terminal is considered to be available; otherwise, it is considered to be unavailable.

[0167] As another example, when the terminal storage state is not less than a set threshold, the wireless access layer cache state is not less than another set threshold, or the amount of collected data is not less than yet another set threshold (i.e., the amount of measured and / or recorded data is large enough to be retained), the terminal measurement and / or recording data is considered to be available; otherwise, it is considered to be unavailable.

[0168] Furthermore, the two examples mentioned above can be combined. That is, if the terminal's battery status meets the aforementioned threshold conditions, and at the same time, the terminal's storage status, the wireless access layer cache status, and the amount of data collected all meet the aforementioned conditions, it can be determined that the data measured and / or recorded by the terminal is available. If any condition is not met, it is considered unavailable, thereby improving the reliability of the determination of whether the data is available.

[0169] Step 4: The terminal sends an indication message to the base station, which indicates whether the data measured and / or recorded by the terminal is available.

[0170] The terminal can send a first message, as described in the previous embodiment, to the base station. The first message carries first indication information to indicate whether the data measured and / or recorded by the terminal is available.

[0171] Step 5: The base station sends an information request to the terminal, which is used to request the data measured and / or recorded by the terminal.

[0172] For example, the information request can be a request message or other types of messages, with the information request carried within other types of messages.

[0173] Step 6: The terminal sends an information response to the base station. Specifically, the terminal can report the data it measures and / or records to the base station.

[0174] Step 7: The base station determines that the terminal needs to enter the RRC_Inactive state.

[0175] After receiving the data reported by the terminal, the base station determines that the terminal can currently enter the RRC_Inactive state. This step can be omitted in some cases.

[0176] Step 8: The base station sends an RRCRelease message to the terminal. The RRCRelease message instructs the terminal to release the connection.

[0177] Step 9: The terminal enters the RRC_Inactive state.

[0178] After receiving the RRCRelease message from the base station, the terminal releases the connection and enters the RRC_Inactive state.

[0179] Based on the embodiment of Scenario 1 above, before entering the idle or inactive state, the terminal reports an indication to the base station, indicating whether the data it has acquired is available. Upon receiving this indication, the base station knows that the terminal's measurement and / or recording data is available. It can then initiate an information request to the terminal to acquire the terminal's data before it enters the idle or inactive state. Alternatively, it can send an indication to the terminal, instructing it to retain or not retain its measurement and / or recording data when entering the idle or inactive state, or to retain or not retain its measurement and / or recording data before entering the idle or inactive state. This achieves reasonable collection and retention of terminal data, reducing waste of terminal resources.

[0180] In one embodiment, Figure 4 shows a signaling interaction flowchart between the terminal and the base station when a terminal enters the RRC_Inactive state and retains the measured and / or recorded data, and then re-enters the RRC_Connected state (the re-connected base station is the same as the previously connected base station). The scenario involves the terminal reporting the retained measured and / or recorded data. This scenario, in subsequent embodiments of this application, is also referred to as Scenario 2. In Scenario 2, the RRC_Inactive state can also be replaced by the RRC_Idle state.

[0181] Referring to Figure 4, the main process steps of scenario 2 (the reconnected base station is the same as the previously connected base station) are described as follows:

[0182] Step 1: The base station determines that the terminal needs to enter the RRC_Inactive state.

[0183] Step 2: The base station sends an indication message to the terminal, indicating that the base station has determined that the terminal needs to enter the RRC_Inactive state.

[0184] Step 3: The terminal determines whether the measurement and / or recording data is available based on its internal conditions and / or the size of the collected data.

[0185] Step 4: The terminal sends an indication message to the base station. This indication message indicates whether the measured and / or recorded data is available. If the data is available, the terminal can also send data acquisition delay information to the base station. The data acquisition delay information can be determined based on the amount of measured and / or recorded data.

[0186] The implementation of steps 1 to 4 is similar to steps 1 to 4 in the aforementioned scenario 1, and will not be repeated here.

[0187] Step 5: The base station determines whether to acquire the data measured and / or recorded by the terminal before RRCRelease based on the indication information reported by the terminal (or the indication information and data acquisition delay).

[0188] Step 6a: If the base station determines that it will acquire the terminal measurement and / or recorded data before RRCRelease, execute steps 5 to 9 of scenario 1. The specific steps are not described in detail.

[0189] Step 6b: If the base station determines that it will not acquire the terminal's measured and / or recorded data before RRCRelease, it sends RRCRelease information to the terminal, including indication information, to instruct the terminal to retain the terminal's measured and / or recorded data, or to instruct the terminal not to retain the terminal's measured and / or recorded data.

[0190] Step 7b: If the base station instructs the terminal to retain the data measured and / or recorded by the terminal, the terminal retains the measured and / or recorded data and then enters the RRC_Inactive state; if the base station instructs the terminal not to retain the data measured and / or recorded by the terminal, the terminal deletes or releases the measured and / or recorded data and then enters the RRC_Inactive state; or deletes or releases the measured and / or recorded data when entering the RRC_Inactive state.

[0191] Step 8b: When the terminal re-enters the RRC_Connected state (the re-connected base station is the same as the previously connected base station), it sends an indication message to the base station to indicate that the terminal has retained the measured and / or recorded data, or to indicate that the measured and / or recorded data is available.

[0192] The terminal can send a first message to the base station, carrying the indication information in the first message, instructing the terminal to retain the measured and / or recorded data.

[0193] Step 9b: The base station sends an information request to the terminal to request the data measured and / or recorded by the terminal.

[0194] Step 10b: The terminal sends an information response to the base station, reporting the data measured and / or recorded by the terminal.

[0195] Based on the embodiment of Scenario 2 above, after the terminal enters the RRC_Inactive state, it retains the measured and / or recorded data. When it re-enters the RRC_Connected state (the re-connected base station is the same as the previously connected base station), it can report indication information to the base station, indicating that it has retained the previously obtained data or that the previously obtained data is available. After receiving this indication information, the base station can initiate an information request to the terminal to obtain the data obtained by the terminal in the previous connected state. This allows the data obtained by the terminal to be reported again when it re-enters the connected state, reducing the probability of the terminal repeatedly obtaining data and reducing the waste of terminal resources.

[0196] In one embodiment, Figure 5 provides a signaling interaction flowchart between the terminal and the base station when the terminal enters the RRC_Inactive state, retains the measured and / or recorded data, and then re-enters the RRC_Connected state (the re-connected base station is different from the previously connected base station). For the scenario where the terminal re-enters the RRC_Connected state and the re-connected base station is different from the previously connected base station, this is also referred to as Scenario 3 in subsequent embodiments of this application, and the previously connected base station is referred to as the first base station, and the currently re-connected base station is referred to as the second base station. The RRC_Inactive state in Scenario 3 can also be replaced by the RRC_Idle state.

[0197] Referring to Figure 5, the main process steps of scenario 3 (the second base station to be reconnected is different from the first base station to be connected previously) are described as follows:

[0198] Steps 1 to 7: Steps 1 to 7 are the interaction process between the terminal and the first base station. This interaction process is the same as the interaction process between the terminal and the base station in Steps 1 to 7 of Scenario 2, and will not be described again.

[0199] Step 8a: When the terminal re-enters the RRC_Connected state from the RRC_Inactive state, it sends an indication message to the second base station, which indicates that the terminal has retained the measured and / or recorded data.

[0200] In addition, the terminal can also report the time information of measurement and / or recording data, and the measurement configuration / network side information of the first base station (such as the AI / ML function / model ID, cell ID, etc. that the measurement and / or recording data is targeted at) to the second base station, so that the second base station can determine whether the data retained by the terminal is suitable for its own network configuration or AI / ML configuration.

[0201] Step 9a: The second base station determines whether the measurement and / or recording data retained by the terminal is applicable to the second base station based on the time information of the measurement and / or recording data reported by the terminal and the measurement configuration / network side information of the first base station.

[0202] Step 10a: If the measurement and / or recording data retained by the terminal is applicable to the second base station, the second base station may send an information request to the terminal to request the acquisition of the measurement and / or recording data retained by the terminal.

[0203] Step 11a: The terminal receives the information request sent by the second base station, sends an information response to the second base station, and reports the measurement and / or recorded data retained by the terminal.

[0204] The following describes another embodiment of Scenario 3, in which the information related to the data reported by the terminal to the second base station is different from that in the previous embodiment.

[0205] Step 8b: When the terminal re-enters the RRC_Connected state from the RRC_Idle state, it sends an indication message to the second base station. This indication message indicates that the terminal has retained the measured and / or recorded data. In addition, the terminal also reports to the second base station the time information, location information, and the AI / ML function / model ID to which the measured and / or recorded data is applicable. The location information includes, for example, the cell ID where the terminal was measuring and / or recording the data.

[0206] Step 9b: The second base station determines whether the measurement and / or recording data retained by the terminal is applicable to the second base station based on the time information, location information, and function / model ID to which the measurement and / or recording data is applicable, etc., of the measurement and / or recording data reported by the terminal.

[0207] Step 10b: If the measurement and / or recording data retained by the terminal is applicable to the second base station, the second base station sends an information request to the terminal to request the acquisition of the measurement and / or recording data retained by the terminal.

[0208] Step 11b: The terminal receives the information request sent by the second base station, sends an information response to the second base station, and reports the measurement and / or recorded data retained by the terminal.

[0209] Based on the embodiment of scenario 3 above, after the terminal enters the RRC_Inactive state, it retains the measured and / or recorded data. When it re-enters the RRC_Connected state (the second base station it reconnects to is different from the first base station it previously connected to), it can report indication information to the second base station, indicating that it has retained the previously obtained data, or indicating that the previously obtained data is available. Simultaneously, the terminal can also report the time information, location information, AI / ML function / model information, etc., associated with the retained data to the second base station, facilitating the second base station's determination of whether the retained data is necessary. After receiving the indication information and data association information reported by the terminal, the second base station determines, based on the data association information, that the data is suitable for its own network configuration or AI / ML function / model. It can then initiate an information request to the terminal to obtain the data obtained by the terminal when it previously connected to the first base station. This ensures that, in the event of a network switch, the data obtained by the terminal can be obtained by the switched base station, reducing the resource waste of the terminal repeatedly acquiring data.

[0210] Based on the above embodiments, this application also provides some embodiments of network-side devices, which are described below.

[0211] Referring to FIG6, in one embodiment, taking an application to a network-side device as an example, a data collection method includes the following steps:

[0212] S601, the terminal enters the radio resource control (RRC) connected state from the RRC idle state or the RRC inactive state, and the network-side device receives a first message sent by the terminal; the first message contains first indication information, which is used to indicate to the network-side device whether the terminal's measurement and / or recording data is available.

[0213] S602a, the network-side device sends an information request to the terminal, or S602b, the network-side device sends a second message to the terminal; the second message contains second indication information, which is used to instruct the terminal to retain or not retain the measurement and / or recording data.

[0214] Step S602a or S602b can be executed if the terminal measurement and / or recording data is available, or it can be executed without the terminal measurement and / or recording data being available. That is, step S602a or S602b can be executed after step S601, or it can be executed independently of step S601. Even if step S601 is not executed, step S602a or S602b can still be executed.

[0215] In a further embodiment, when the terminal's measurement and / or recording data is available, after the network-side device sends an information request to the terminal, the method further includes: the network-side device receiving the measurement and / or recording data reported by the terminal.

[0216] In another embodiment, referring to FIG7, and still taking an application to a network-side device as an example, a data collection method includes the following steps:

[0217] S701, the network-side device sends a third message to the terminal; the third message includes third indication information, which is used to indicate to the terminal that the network-side device has determined that the terminal needs to enter the radio resource control inactive / idle state.

[0218] S702, Receive a first message sent by the terminal. The first message contains first indication information, which is used to indicate to the network-side device whether the terminal's measurement and / or recording data is available.

[0219] S703a, before the terminal enters the Radio Resource Control (RRC) idle state or the RRC inactive state from the RRC connected state, the network-side device sends an information request to the terminal; or, S703b, the network-side device sends a second message to the terminal; the second message contains second indication information, which is used to instruct the terminal to retain or not retain the measurement and / or recording data.

[0220] Step S702 can be executed when the terminal receives a third message, or it can be executed without the terminal receiving a third message as a prerequisite. That is, step S702 can be executed after step S701, or it can be executed independently of step S701. Even if step S701 is not executed, step S702 can still be executed.

[0221] Specifically, step S703a or S703b can be executed if the terminal measurement and / or recording data is available, or it can be executed without the terminal measurement and / or recording data being available. That is, step S703a or S703b can be executed after step S702, or it can be executed independently of step S702. Even if step S702 is not executed, step S703a or S703b can still be executed.

[0222] Referring again to Figure 7, in a further embodiment, if the terminal's measurement and / or recording data is available, after the network-side device sends an information request to the terminal, it further includes:

[0223] S704, before the terminal enters the Radio Resource Control (RRC) idle state or the RRC inactive state from the RRC connected state, the network-side device receives the measurement and / or recording data reported by the terminal.

[0224] S705, after receiving the reported measurement and / or recording data, the network-side device sends a connection release message to the terminal, instructing the terminal to enter the Radio Resource Control (RRC) idle state or the RRC inactive state from the RRC connected state.

[0225] This application also provides a scenario where the terminal switches networks, specifically when switching from a first network-side device to another network-side device. Taking an application to a second network-side device as an example, the data collection method follows these steps.

[0226] When a terminal enters a connected state from a radio resource control (RRC) idle state or a RRC inactive state, the second network-side device receives a first message sent by the terminal. The first message contains first indication information, which is used to indicate to the second network-side device whether the terminal's measurement and / or recording data is available.

[0227] When the terminal's measurement and / or recording data is available, the second network-side device sends an information request to the terminal, or the second network-side device sends a second message to the terminal; the second message contains second indication information, which is used to indicate to the terminal that its measurement and / or recording data is not applicable to the second network-side device, or to indicate to the terminal whether to retain or not retain the measurement and / or recording data.

[0228] In a further embodiment, when the terminal's measurement and / or recording data is available, after the second network-side device sends an information request to the terminal, the method further includes: the second network-side device receiving the measurement and / or recording data reported by the terminal.

[0229] In a further embodiment, when the first indication information indicates that the terminal's measurement and / or recording data is available, the second network-side device further receives information associated with the measurement and / or recording data sent by the terminal. This information associated with the terminal's measurement and / or recording data may include at least one of the following: the time of the measurement and / or recording data; the latency information for reporting the measurement and / or recording data; the location information of the terminal when measuring and / or recording the data; the measurement configuration information of the first network-side device when measuring and / or recording the data; the AI / ML function information applicable to the measurement and / or recording data; and the AI / ML model information applicable to the measurement and / or recording data.

[0230] When a terminal switches from a first network-side device to a second network-side device, the second network-side device can determine whether the terminal's measurement and / or recording data is applicable to the second network-side device based on the information associated with the measurement and / or recording data sent by the terminal, thus avoiding collecting data from the terminal that is not applicable to itself.
