According to the tenth aspect, the access management network element directly obtains the first location privacy setting data from the data management network element, and performs a corresponding location service operation based on the first location privacy setting data, to prevent location information of the user terminal from being illegally obtained, thereby effectively protecting the location information of the user terminal.
With reference to the tenth aspect, in a possible implementation, performing, by the access management network element, a location service operation based on the first location privacy setting data further includes the following.
If the first location privacy setting data is allowing positioning but requiring to notify a user, the access management network element sends a notification message to the user terminal by using an access network, and requests to obtain location information of the user terminal.
If the first location privacy setting data is allowing positioning but not requiring to notify a user, the access management network element requests to obtain location information of the user terminal.
If the first location privacy setting data is requiring to notify a user and being authorized by the user to determine whether to allow positioning, the access management network element sends a notification message to the user terminal by using an access network, and when receiving a location permission message from the user terminal, requests to obtain location information of the user terminal.
