A radio communication system enabling a plurality of radio communication systems to perform voice communication with each other via a transceiving channel, comprising:

• a memory for storing a channel number specifying said transceiving channel, one of a plurality of group codes allocated to each transceiving channel, an ID code which is unique to said radio communication system, and names of the other radio communication systems;
• and
• a control unit for controlling said voice communication,
• wherein, on condition that a channel number set in a specific radio communication system having a name that is selected by a user from among said names stored in said memory is identical to said channel number stored in said memory, and that a group code set in said specific radio communication system is identical to said group code stored in said memory, said control unit performs one-to-one communication with said specific radio communication system.
