[0468] The data collection method provided by the present disclosure is described below in combination with an exemplary embodiment, and the data collection method can include the following steps:

[0469] 1. A core network device sends a first message, the first message being used for requesting a terminal device to perform data collection, wherein the collected data is used for managing an artificial intelligence (AI) positioning model and / or a machine learning (ML) positioning model.

[0470] The first message can be an LPP request location information message.

[0473] A range of data collection;

[0474] A trigger condition of data collection;

[0475] PRS required for data collection;

[0477] Exemplarily, different contents in the first message described above can be sent through different messages, for example, the range of data collection is sent through an LPP request location information message, and the PRS required for data collection is sent through an LPP provide assistance information message.

[0478] 2. A terminal device receives the first message.

[0479] Optionally, after receiving the first message, the terminal device collects data according to the first message.

[0480] Case I:

[0481] When the first message includes a range of data collection, the terminal device can measure PRS in the range of data collection to collect data, or when the first message includes the range of data collection, the terminal device can measure PRS to collect data when in the range of data collection. Wherein the range of data collection can be represented by one or more of PRS ID, PCI, CGI, TRP ID or geographical location.

[0482] When the first message includes at least one PRS ID, the terminal device measures PRS in the range of PRS corresponding to each PRS ID to collect data.

[0483] When the first message includes at least one PCI, the terminal device collects data when the serving cell belongs to any one of the physical cells corresponding to the PCI. That is, when the terminal device enters any one of the physical cells corresponding to the PCI, the terminal device starts to collect data, and when the terminal device enters other physical cells other than the physical cells corresponding to each PCI, the terminal device does not collect data or stops collecting data.

[0484] When the first message includes at least one CGI, the terminal device starts data collection when located in the global coverage range of the cell corresponding to the CGI, and does not collect data or stops collecting data when located outside the global coverage range of the cell corresponding to the CGI.

[0485] When the first message includes at least one TRP ID, the terminal device measures PRS in the range of PRS transmitted by the TRP corresponding to each TRP ID to collect data.

[0486] When the first message includes a geographical location, the terminal device starts to collect data when located in the geographical location, and does not collect data or stops collecting data when located outside the geographical location.

[0487] When the first message includes a combination of any of the above, the terminal device can collect data in the union or intersection range of the ranges corresponding to the multiple items.

[0488] Case II:

[0489] When the first message includes a trigger condition for data collection, the terminal device collects data according to the trigger condition for data collection.

[0490] The trigger condition of the data collection includes at least one of a first trigger condition based on a data collection range or a second trigger condition based on a measurement result of a PRS.

[0491] When the trigger condition of the data collection includes the first trigger condition based on the data collection range, the terminal device starts the data collection when the location meets the first trigger condition based on the data collection range, and stops or does not start the data collection when the location does not meet the first trigger condition based on the data collection range.

[0492] For example, the terminal device starts the data collection when located within the range of the data collection, and stops the data collection when located outside the range of the data collection.

[0493] When the trigger condition of the data collection includes the second trigger condition based on the measurement result of the PRS, the terminal device starts the data collection when the measurement result of the PRS meets the second trigger condition based on the measurement result of the PRS, and stops or does not start the data collection when the measurement result of the PRS does not meet the second trigger condition based on the measurement result of the PRS.

[0494] For example, the terminal device starts the data collection when detecting the PRS, and stops the data collection when not detecting the PRS.

[0495] For example, the terminal device starts the data collection when measuring the RSRP of the PRS less than or equal to a first signal quality threshold, and stops the data collection when measuring the RSRP of the PRS greater than the first signal quality threshold.

[0496] For example, the terminal device starts the data collection when measuring the RSRPP of the PRS less than or equal to a second signal quality threshold, and stops the data collection when measuring the RSRPP of the PRS greater than the second signal quality threshold.

[0497] Case three:

[0498] When the first message includes a PRS required to be measured for collecting the data, the terminal device can measure the PRS required to be measured for collecting the data. The PRS required to be measured can be indicated by one or more of a PRS ID, a PCI, a CGI, a TRP ID or a PRS configuration ID.

[0499] For example, when the first message includes at least one PRS ID, the terminal device measures a PRS corresponding to each PRS ID for collecting the data.

[0500] For example, in the case that the first message comprises at least one PCI, the terminal device measures PRS in a physical cell corresponding to each PCI for data collection.

[0501] For example, in the case that the first message comprises at least one CGI, the terminal device measures PRS in a cell global coverage corresponding to each CGI for data collection.

[0502] For example, in the case that the first message comprises at least one TRP ID, the terminal device measures PRS transmitted by a TRP corresponding to each TRP ID for data collection.

[0503] For example, in the case that the first message comprises at least one ID of PRS configuration, the terminal device measures PRS corresponding to each ID of PRS configuration for data collection.

[0504] Case four:

[0505] In the case that the first message comprises a data object for data collection, the terminal device can collect the data object for data collection. The data object for data collection comprises one or more of a measurement result of PRS, location information of the terminal device, or a positioning method for determining the location information of the terminal device. The measurement result of PRS comprises, but is not limited to, any one or more of RSTD, RSPP, RSRPP, or TOA.

[0506] For example, in the case that the first message comprises a measurement result of PRS, the terminal device needs to collect the measurement result of PRS when performing data collection.

[0507] For example, in the case that the first message comprises location information of the terminal device, the terminal device needs to collect the location information of the terminal device in the process of measuring PRS when performing data collection.

[0508] For example, in the case that the first message comprises a positioning method for determining the location information of the terminal device, the terminal device needs to collect the positioning method for determining the location information of the terminal device in the process of measuring PRS when performing data collection.

[0509] The terminal device collects data in an RRC non-connected state.

[0510] 3. The terminal device sends the collected data to the core network device.

[0511] In an optional implementation, after completing the data collection, the terminal device can save the collected data and send an LPP provide location information message to the core network device to send the collected data to the core network device through the LPP provide location information message.

[0512] In the above examples, the terminal device sends the collected data in the RRC connected state.

[0513] For example, the terminal device collects data in the RRC idle state or the RRC inactive state, and then sends the collected data in the RRC connected state.

[0514] 4. In the above examples, after sending the first message to the terminal device, the core network device also sends a first NRPPa message carrying an activation indication to the access network device, and then the access network device sends the activation indication to the terminal device to activate the terminal device to collect data.

[0515] In the above examples, after receiving the first message, the terminal device also receives the activation indication, and then collects data according to the activation indication.

[0516] On the other hand, the core network device also sends a second NRPPa message carrying a deactivation indication to the access network device, and then the access network device sends the deactivation indication to the terminal device to deactivate the terminal device to collect data.

[0517] After completing the data collection, the terminal device can send the collected data to the core network device.

[0518] FIG. 3 is a flowchart of a data collection method according to an embodiment of the present disclosure. As shown in FIG. 3, the method is performed by a core network device, and the method includes:
