PURPOSE:To simplify extremely the redial operation by operating a redial switchwhile eliminating the need for the redialing by a series of normal calling operation which has been required for a conventional radiotelephony. CONSTITUTION:When a redial switch 14 is depressed before on-hook in a mobile station 1 after talking, the depression of the redial switch 14 is detected by a control section 13. When the control section 13 confirms the start of the redial switch 14, a signal generating section 12 is started and generates the redial signal. The redial signal from the signal generating section 12 is modulated by a transmission section 11 and sent from a transmission antenna 4. The redial signal received by a reception antenna 5 of a base station 2 is demodulated by a reception section 21 and inputted to a signal detection section 22. When the redial signal is detected by the signal detection section 22, the redial signal is inputted to a control section 23, the control section 23 uses the redial signal to disconnect once a line relay 25, then applies the connecting state again. |
