[0354] In some embodiments, the AMF receives a trigger condition that triggers the initiation of a positioning process initiated by the network side for data collection. The trigger may come from the AMF itself. Or the trigger may come from other entities in the network, such as the Network Data Analytics Function (NWDAF), or Operation Administration and Maintenance (OAM), or the next generation Node B (gNB), or other nodes in the core network. When the trigger comes from other nodes in the network, the node may further instruct the AMF on the content of the positioning data collection, such as the type of measurement information collected, whether to collect positioning coordinates, whether to collect quality indicators corresponding to positioning coordinates, whether to collect timestamps corresponding to data samples, the number of data samples, and the quality of service (QoS) of data collection samples. Specifically, the following data collection methods may be included:

[0355] Method 1: The terminal performs Positioning Reference Signal (PRS) measurements. The terminal measures the PRS, obtains measurement values, and simultaneously obtains the terminal's coordinates (e.g., via Bluetooth, Wi-Fi, etc.). The terminal reports the measurement values ​​and corresponding coordinates. It can also request the reporting of quality indicators or timestamps corresponding to the measurement values ​​and coordinates.

[0356] Method 2: The terminal performs PRS measurement and obtains the measured value. The terminal reports the measured value, and the LMF calculates the terminal's coordinates using a positioning algorithm. The LMF can also request the measurement value and the corresponding quality indicators or timestamp.

[0357] Method 3: Configure the corresponding channel sounding reference signal (SRS) transmission, the terminal side sends the SRS, the corresponding TRP is measured, and the measurement results are obtained. The corresponding TRP reports the measurement results. The terminal reports the coordinates of the terminal. At the same time, it can also request to report the measurement quantity and the quality index corresponding to the coordinates or the timestamp, etc.

[0358] Method 4: Configure the corresponding SRS transmission, the terminal sends SRS, the corresponding TRP performs measurement, and obtains the measurement results. The corresponding TRP reports the measurement results. The LMF calculates the coordinates of the terminal based on the measurement results. At the same time, it can also request to report the measurement quantity and the quality index corresponding to the coordinates or the timestamp, etc.

[0359] In some embodiments, QoS requirements for data collection may also be included, such as latency requirements. For example, latency requirements may include real-time, (near) real-time, or no latency requirements. The PRS configuration information for data collection may also include information about how many TRPs are used to send the information and the PRS mode used.

[0360] In some embodiments, in response to a trigger to initiate a positioning process for data collection, the AMF initiates a positioning request to the LMF. The positioning request may further include specific data collection requirements (please refer to the above embodiments for specific details) and QoS requirements, such as latency requirements. For example, latency requirements may include real-time, (near) real-time, no latency requirements, the number of samples for data collection, etc. The PRS configuration information for data collection, such as the number of TRPs sending information and the PRS mode used, may also be included.

[0361] In some embodiments, the LMF initiates a positioning process for a specific terminal based on the data collection requirements and collects the corresponding data. The specific process and collection process refer to the data collection method in the above embodiments.

[0362] In some embodiments, when the positioning data that meets the requirements is collected, LMF returns the collected positioning data to AMF

[0363] In some embodiments, when the positioning data that meets the requirements is not collected, the LMF returns the reason why the positioning data that meets the requirements is not collected to the AMF and stops collecting data.

[0364] In some embodiments, when the LMF collects data samples that meet the requirements, the LMF returns the collected data samples to the AMF. If the LMF does not collect samples that meet the requirements, the LMF feedbacks the cause of the error. For example, it is a terminal problem, or the PRS transmission does not meet the requirements, etc.

[0365] In some embodiments, the AMF sends the collected data samples to the requesting node of the data collection

[0366] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods.
