[0207] In step S2101a, the first network element sends a fourth message to the terminal device.

[0208] In some embodiments, the terminal device can receive the fourth message. For example, the terminal device can receive the fourth message sent by the first network element. For another example, the terminal device can also receive the fourth message sent by another entity.

[0209] In some embodiments, the first network element can be an LMF.

[0210] In some embodiments, the fourth message is used to request the terminal device to send a first condition.

[0211] In some embodiments, the fourth message can be a Location Positioning Protocol (LPP) message.

[0212] In step S2102a, the terminal device sends the first condition to the first network element.

[0222] In some embodiments, the first condition can be one or more association IDs (identifiers), which can be used to indicate additional conditions (i.e., UE-side additional conditions) on the terminal device side when collecting data. After the access network device obtains the first condition, it can compare the association ID corresponding to the training data used to train the first model and / or the first function with the association ID of the data used for model inference through the first model and / or the first function, to determine whether the first model and / or the first function can be used. For example, if the association ID corresponding to the training data used to train the first model and / or the first function is the same as the association ID of the data used for model inference through the first model and / or the first function, it is determined that the first model and / or the first function can be used; if the association ID corresponding to the training data used to train the first model and / or the first function is different from the association ID of the data used for model inference through the first model and / or the first function, it is determined that the first model and / or the first function cannot be used.
