Because FIG. 7A and FIG. 7B are a subsequent step of FIG. 5A and FIG. 5B, FIG. 5C and FIG. 5D, or FIG. 6A and FIG. 6B, the location privacy setting data, of the UE, stored in the UDM is the first location privacy setting data.

Step S305: The V-GMLC sends the location service request to the AMF. Correspondingly, the AMF receives the location service request from the V-GMLC. The location service request may be, for example, a Namf_Location_Provide_positioningInfo_request.

Optionally, the location service request includes action indication information, to be specific, includes action indication information obtained by converting the first location privacy setting data by the GMLC, and the action indication information is used to indicate the AMF to perform a corresponding location service operation. For example, if the first location privacy setting data is allowing positioning but requiring to notify a user, the action indication information is used to indicate the AMF to notify the user, and request to obtain the location information of the UE.

Step S306: The AMF sends the location privacy setting data obtaining request to the UDM. Correspondingly, the UDM receives the location privacy setting data obtaining request from the AMF.
