Data processing system in which distance measurement is performed, control method therefor, and storage medium

A control method for a data processing system comprising a first image forming apparatus, a second image forming apparatus, and a mobile terminal, wherein

• the first image forming apparatus is configured to perform, with the mobile terminal, first wireless communication and second wireless communication for performing distance measurement with accuracy higher than accuracy in the first wireless communication,
• the second image forming apparatus is configured to perform, with the mobile terminal, the first wireless communication, and not to perform the second wireless communication, and
• the control method comprises the following steps to be performed in the mobile terminal:
• a distance calculation step of substituting received radio wave intensity of the second image forming apparatus in the first wireless communication between the mobile terminal and the second image forming apparatus, into a distance calculation equation which is based on the received radio wave intensity of the first image forming apparatus in the first wireless communication and on a result of distance measurement by the second wireless communication performed between the mobile terminal and the first image forming apparatus, thereby calculating a distance from the mobile terminal to the second image forming apparatus;
• and
• a derivation step of
• acquiring received radio wave intensity of the first image forming apparatus in the first wireless communication between the mobile terminal and the first image forming apparatus, and acquiring a result of distance measurement by the second wireless communication between the mobile terminal and the first image forming apparatus;
• and
• deriving the distance calculation equation for calculating a distance from the mobile terminal to the second image forming apparatus by using the acquired received radio wave intensity of the first wireless communication and the acquired result of distance measurement by the second wireless communication, while excluding the first image forming apparatus for which the result of distance measurement by the second wireless communication is equal to or greater than a threshold value.
