摘要： Each mobile terminal apparatus measures receiving power or receiving quality of a signal received from a radio communication apparatus. If a plurality of mobile terminal apparatuses in which the receiving power or the receiving quality is lower than or equal to a determined threshold are detected, then a communication control apparatus selects a mobile terminal apparatus made to function as a relay station from the plurality of mobile terminal apparatuses detected on the basis of a result of measuring the receiving power or the receiving quality. The mobile terminal apparatus selected relays communication between the radio communication apparatus and a mobile terminal apparatus which does not function as a relay station.
