SOLUTION: A first radio mobile terminal alternately repeats, before starting data communication with a second radio mobile terminal, a connection waiting signal transmission period during which power down for stopping radio communication and connection waiting signal transmission are repeated and a connection waiting receiving period for receiving a connection waiting signal or a connection request signal from a second radio mobile terminal.
