The communication control method includes acquiring, by the user equipment, position information indicating a position of the user equipment. The communication control method includes acquiring, by the user equipment, output result data from the position information by using the first divided trained model. The communication control method includes transmitting, by the user equipment, a second message including the output result data to the network node.
