Each block of 11 to 16 constitutes the first slave unit 17 of the wireless telephone device. The second slave unit 20 has the same configuration as the first slave unit 17, and both the first slave unit 17 and the second slave unit 20 are slave units registered in the master unit 19.

The operation of the radio telephone apparatus configured as described above will be described below with reference to the flowcharts of FIGS.

First, the initial setting will be described with reference to the flowchart of FIG.

When the user of the wireless telephone device receives an individual incoming call to each slave unit registered in the master unit using the master unit key operation unit 4 of the master unit 19, and the slave unit cannot respond. Input is made as to whether or not the incoming call is to be transmitted to the other registered slaves, and if the incoming call is to be transmitted, which slave is to be notified or simultaneous incoming call is to be made (step 1). This input information is transmitted to the incoming call management unit 8 via the master unit control unit 18. The incoming call management unit 8 stores this input information (step 2).

Next, the operation when receiving a call will be described with reference to the flowchart of FIG. First, when an individual incoming call for the first slave unit 17 registered in the master unit 19 is transmitted from the telephone line to the dial unit 1, the dial unit 1 transmits the signal to the master unit control unit 18 (step 3). Receiving this, the master unit control unit 18 sets the extension number of the first slave unit 17 in the incoming call signal. This incoming call signal is converted into a radio signal by the base unit radio section 5 and output as a radio wave through the base unit antenna 6 (step 4). After that, it is confirmed whether there is an incoming call response signal from the child device (step 5) (step 7).
When the incoming call response signal is received for a certain period of time, a call between the child device and the telephone line is established (step 6). When the incoming call response signal is not received, the parent device control unit 18 informs the incoming call management unit 8. And sends a signal indicating that there is no individual incoming call response to the first slave unit 16. Upon receipt of this signal, the incoming call management unit 8 retrieves the stored information of another specific slave unit that conveys the incoming call when there is no individual incoming call response to the first slave unit 17 (step 8). If the information that the second child device 20 is another specific child device is entered (step 9), this information is transmitted to the parent device control unit 18. The base unit controller 18 creates an incoming call signal based on this information (step 10). That is, the extension number of the second handset 20 is set here. The incoming call signal is converted into a radio signal by the base unit radio unit 5 and output as a radio wave via the base unit antenna 6. Here, when the power of the second handset 20 is ON and within the range in which the second handset 20 can communicate with the base unit, the second handset 20 receives the wireless signal and transmits an incoming call response signal to the base unit. To do. In this way, the base unit 10-
A wireless communication path is established between the second cordless handsets 20 (step 1
1), it becomes possible to call the second cordless handset 20 (step 12). Further, if it is assumed that the information of the handset, which is stored in the incoming call management unit 8 and conveys the incoming call when there is no individual incoming call response to the first handset 17, includes information for switching to the simultaneous incoming call (step 9), The information is transmitted to the base unit control unit 18, and the base unit control unit 18 having received this information creates an incoming call signal for simultaneous incoming call (step 13). This incoming call signal is converted into a radio signal by the base unit radio unit 5 and output as a radio wave via the base unit antenna 6. In this way, the incoming call can be transmitted to all the slave units that are within the communication range with the master unit and whose power is ON (step 14).

As described above, according to the present embodiment, by providing the incoming call management unit in the base unit, it is impossible to notify the incoming call because the power is off or the call is out of the range where the call with the base unit is possible. An individual incoming call for a slave unit is registered in the master unit, and it can be notified to another slave unit that is within the range in which communication with the master unit is possible and whose power is ON, or can be switched to simultaneous incoming call.
