The operation of the wireless telephone device configured as described above will be described below. As described above, this wireless telephone device has two modes of the personal mode and the common mode when receiving a call. The personal mode is a conventional method of responding to an incoming call, and is a mode in which a call is sounded only to the wireless handset 31 corresponding to the telephone number dialed by the caller, the incoming call can be answered, and the call can be connected. The common mode is
In this mode, even if the sender is a wireless slave device 31 other than the wireless slave device 31 of the party corresponding to the telephone number that he / she has been willing to respond to, the incoming call can be answered if the location is registered in the same wireless zone. The setting of the common mode is executed by one wireless slave device 31 in the wireless zone performing a common mode setting operation.

FIG. 2 is a flow chart showing the operation when the common mode is executed in this radio telephone device.
The mode operation unit 53 on the wireless slave device 31 is operated to set the common mode (# 1). The first control unit 38 sends the mode information to the mode setting unit 54, and the inter-connector wireless interface 3
5 to send to the connection device 41 (#)
2). The mode information is transmitted from the antenna unit 37 to the antenna unit 42 of the connection device 41 (# 3). The inter-slave unit wireless interface 43 of the connection device 41 receives the mode signal (# 4). The second control unit 45 checks whether the control channel of the line is idle (# 5), and if the channel is not available, checks whether the timer of the second control unit 45 has reached the specified time (# 14). . If it does not time out, check the free status further. If it is timed out, the free state is checked after a predetermined time (# 1).
5). If the reconfirmation is completed, the second control unit 45 sends a mode setting refusal notification to the first control unit 38 of the wireless slave device 31 (# 16). The first control unit 38 uses the confirmation tone generation unit 55.
An error sound is created and a notification is generated from the handset 33 (# 17). When the control channel is idle, the second control unit 45 sends a mode information signal to the control channel, and instructs the connection device ID storage unit 52 to send the ID of the connection device (# 6). The communication unit 44 transmits the mode information signal and the connection device ID data signal to the communication unit 47 of the control device 46 on the control channel (# 7). Communication unit 47
Then, it is determined whether or not there is an error in the data (# 8), and if there is an error, the communication section 44 retransmits the data (# 18). If there is no error, the third control unit 51 extracts the mode information and the connection device ID data from the control channel, and the mode management unit 57.
To (# 9). The mode management unit 57 creates and manages a table that associates the ID of the connection device 41 that has sent the mode information with the mode information (# 10). The third control unit 51 sends a mode setting completion notification to the first control unit 38 of the wireless slave device 31 through the reverse route of transmitting the mode information from the inorganic slave device 31 to the control device 46 (# 11). The first control unit 38 instructs the receiver confirmation tone generation unit 55 to generate a mode setting confirmation tone (# 12), and causes the confirmation display creation unit 56 to display the mode display on the display unit 39. Instruct (# 13). A confirmation tone flows from the handset 33, and the setting mode is displayed on the display unit 39.

FIG. 3 is a flow chart showing the operation when there is an incoming call in this wireless telephone device. Controller 4
The third control unit 51 of 6 determines whether the wireless slave device 31 is in the on-hook state or the off-hook state (# 19), and if it is an on-hook invitation, it determines the incoming call detection to the wireless slave device (# 20). . If the station line interface 49 has not detected an incoming call, the third control unit 51 sends a ringing tone stop request to the first control unit 38 of the wireless slave device (# 21). By the way, the transmission of the ringing tone stop request is sent to stop the ringing tone when the ringing tone is already in the ringing state, and is not always sent to the wireless handset when there is no incoming call. On the other hand, when an incoming call is detected, the third control unit 51
Searches the location registration management table of the location registration management unit 50 for the wireless zone in which the target slave unit is registered, and obtains the connection device ID (# 22). The connection device ID is collated with the mode management table of the mode management unit 57 to determine whether the destination wireless zone is the common mode (# 23).
In the common mode, the third control unit 51 transmits a ring tone generation request to all the wireless slave devices whose positions are registered in the same wireless zone via the connection device 41 (# 24). If at least one of the wireless slaves is in an off-hook state and the third control unit 51 receives the off-hook data, a ringing tone stop request for stopping the ringing tone is transmitted to the wireless slave. Yes (# 26). Then, the off-hook wireless cordless handset is connected to the station line (# 27). On the other hand, if the third control unit 51 does not receive the off-hook data,
After the ringing tone is still generated, it is determined again whether the wireless slave device is in the on-hook state (# 19), and then the incoming call detection is determined (# 20). At that time, if the caller disconnects the call, the incoming call is not detected and the ring tone needs to be stopped, and the third control unit 51 transmits a ring tone stop request to the wireless handset (#
21).

In addition, the mode of the destination is determined # 23.
If the destination mode is the personal mode, the ring tone generation request is transmitted only to the wireless slave device corresponding to the telephone number dialed by the caller (# 19). When the wireless slave unit enters the off-hook state and the off-hook data is received by the third control unit 51, a ring tone stop request is transmitted to the wireless slave unit (# 30), and the wireless slave unit is connected to the station line. Yes (# 3
1). If the wireless slave unit is not in the off-hook state, the same process as in the case of the common mode is performed.

When it is determined that the current state of the wireless slave device is the off-hook state (# 19), the process shifts to the determination of whether the off-hook state transits to the on-hook state (# 32). The transition to the on-hook state means that the wireless handset disconnected the call, so the station line is released (# 3
6). On the other hand, it is determined whether or not the call termination signal is detected by the central line interface 49 even in the off-hook state (# 33). If the call termination signal is detected, the caller disconnects the call. Therefore, the station line is released (# 3
6). When the control unit 51 of the subject 3 receives the dial data in the off-hook state, the DTMF signal is transmitted from the station line interface 49 (# 35).

According to this embodiment, the control device 46 can recognize whether or not the wireless zone in which the wireless handset 31 of the destination is registered is in the common mode. Hereinafter, the second aspect of the present invention
