PURPOSE:To obtain a system with highly effective utility of frequency by devising the method such that a mobile radio set in communication with one radio base station executes diversity communication with other radio base station located in the vicinity. CONSTITUTION:The communication between each mobile radio set 100 and a radio base station 30-1 or 30-2 is subjected to exchange connection by a gate exchange 20 in the traveling object communication adopting the time division communication system using small zone constitution. Then each mobile radio set 100 is controlled in a way that the mobile radio set 100 uses one radio channel to communicate with one of the radio base stations 30-1, 30-2 and also uses one of radio channels including the radio channel used as above to communicate with the other of the radio base stations 30-1, 30-2. Thus, the system with highly efficient frequency utility is built up. |
