ABSTRACT:
A wireless-phone system makes it possible to simplify a radio section of the base station for relaying the predetermined data sent from a mobile wireless terminal by means of a first frequency, and for transmitting/receiving the control data to mobile wireless terminals which are in a reception waiting state by means of a second frequency. A first data sent from a first mobile wireless terminal, out of the bi-directional communications between the first and second mobile wireless terminals, is relayed at a base station to transmit it to the second mobile wireless terminal, and a second data sent from the second mobile wireless terminal is directly transmitted to the first mobile wireless terminal. Thereby, the base station is able to ensure a free period which is allocated to switching of the oscillation frequency of the frequency-selecting oscillators, and to transmission and reception of the control data by the use of the second frequency.
