The radio terminal comprises a base station communication unit (110) capable of direct communication with a specific wide-area communication network provided by a specific operator, an ad-hoc communication unit (120) capable of forming a first ad-hoc communication network (AH1) with a plurality of other mobile terminals (MS1 to 3), and an operator determination unit (133) for determining whether or not a first connected operator which provides a first connected wide-area communication network (WAN1) connected via the other mobile terminals (MS1 to 3) is the same as the specific operator. The operator determination unit (133) performs the determination on the basis of operator identification information included in a control signal. If the first connected operator is judged to be the same as the specific operator, the ad-hoc communication unit (120) forms the first ad-hoc communication network (AH1) with the other mobile terminals (MS1 to 3).
