<p>In a radio communication system including a base station and a radio terminal constituting a radio network for business use, a reception side radio terminal for communication via a base station adjusts the voice level according to the communication signal level of the voice data transmitted from a transmission side radio terminal, accumulates the adjustment value data on the voice level adjusted and the connection number of the transmission side radio terminal, and returns the measurement value data to the transmission side radio terminal. The transmission side radio terminal adjusts the microphone level according to the adjustment value data on the voice level returned and transmits voice data which has been level-adjusted. Moreover, at the next communication start, the connection number is correlated and the adjustment value data accumulated is automatically transmitted. Furthermore, in an area where communication is enabled without using any base station, direct communication is performed between radio terminals. Thus, it is possible to provide a radio communication system and a radio terminal thereof in which voice level is accurately adjusted to compensate the change of a person and a use environment.</p> |
