PURPOSE:To reduce the power consumption of a radio telephone set and to simplify the processing of a radio line controller by providing a dedicated operation switch for registering a current radio zone wherein a radio telephone set is present and also providing a function for storing the radio zone number. CONSTITUTION:The radio telephone set 3 is provided with a means which sends out a position registration request signal when the operation switch is operated, and a radio connection device 12 is provided with a means which sends out the position registration request signal and identification number from the radio telephone set 13 and the reception level of a received signal; and a radio line controller 11 is provided with a means which compares the level of the received signal from the radio connection device, and a means which stores the radio zone of the radio connection device 12 with maximum level and the radio telephone set 13 in corresponding relation, and a position registering means is made independent of a calling procedure. Then the position of the radio telephone set is registered in the radio line controller through the switch operation of the radio telephone set for a position registration request. Consequently, a radio telephone system of simple circuit constitution is realized and the power consumption of the radio telephone set can be reduced. |
