Abstract

PURPOSE: To send control signal in the form of an analog signal during a telephone call and then prevent a caller from having a singing in his or her ears by providing a means which sends an on-hook PB signal to a fixed equipment when an on-hook input is generated and a means which recognizes the on-hook recognition when the fixed equipment receives the on-hook PB signal from the mobile equipment. CONSTITUTION: The caller presses an on-hook button 124 to places the mobile equipment 112 in the on-hook state when the mobile equipment 112 and fixed equipment 101 are in the call state with each other. The mobile equipment 112 monitors the input of the on-hook button 124 during a telephone call, and sends the on-hook PB signal 'A' to the fixed equipment 101 once detecting its input. The PB signal is generated by a PB signal transmission part 121 and sent to the fixed equipment 101 through a speech processing circuit 118, a radio transmission and reception part 117, and an antenna 116. The fixed equipment 101 waits for the PB signal 'A' and sends a radio line disconnection request to the mobile equipment 112 once receiving the PB signal from the mobile equipment 112 to disconnect the radio line from the mobile equipment 112.

The operation of the third embodiment will be described below.

First, the dedicated mobile unit 1112 and the dedicated stationary unit 1
When the user of the dedicated mobile device 1112 tries to receive the service of the function A while 111 is in a call, the function A button 12
22a is pressed. The dedicated mobile device 1112 monitors the input of the button during a call (S1301), and when the input of the function A button 1222a is detected, the PB signal “B” for the function A is sent to the dedicated fixed device 1111. It is transmitted (S1302). The PB signal transmission is performed by the PB signal transmission unit 1
A PB signal is created at 217 and transmitted to the dedicated stationary device 1111 via the voice processing circuit 1214, the wireless transmission / reception unit 1213, and the antenna 1212.

The main unit 1101 waits for a PB signal from the dedicated mobile unit 1112 during a call (S1).
501), when the PB signal “B” for function A is received from the dedicated mobile device 1112 (S1502), the service of function A is executed (S1504). For example, when the function A is the registration of the absence setting, the dedicated mobile device 1112 that has received the PB signal “B” is set to the absence state.

Dedicated mobile unit 1112 and dedicated fixed unit 1111
If the user of the dedicated mobile device 1112 wants to end the call, the end button 1220 is pressed. The dedicated mobile device 1112 monitors the input of the button (S1301), and when the input of the call end button 1220 is detected, the PB signal “A” for the end call is transmitted to the dedicated fixed device 1111.

The main unit 1101 waits for a PB signal from the dedicated mobile unit 1112 during a call (S1).
501), when the PB signal “A” for ending the call is received from the dedicated mobile device 1112 (S1502), a wireless line disconnection request is transmitted to the dedicated fixed device 1111 (S150).
3).

In the fixed station 1111, during a call,
When waiting for a wireless line disconnection request from the main device 1101 (S1401) and receiving a wireless line disconnection request from the main device 1101, the dedicated mobile device 1 issues the wireless line disconnection request.
112 to the dedicated mobile device 1112 (S1402).
And disconnects the wireless line with (S1403).

To transmit the wireless line disconnection request information to the dedicated mobile unit 1112, the modem 1207 modulates the wireless line disconnection request signal into an analog signal, and the voice processing circuit 1
205, wireless transceiver 1206 and antenna 1208
To the dedicated mobile device 1112 via.

The dedicated mobile unit 1112 is always waiting for a wireless line disconnection request from the dedicated fixed unit 1111 (S
1301), when the wireless line disconnection request from the dedicated fixed device 1111 is received, the wireless line with the dedicated fixed device 1111 is disconnected.

By carrying out the third embodiment described above,
In the key telephone device, when a dedicated telephone is wirelessly connected, even if the user of the dedicated mobile device 1112 pushes the end button 1220 or the function button 1222 during a call, the pushing information is transmitted to the human ear. Since the PB signal which is not unpleasant is transmitted to the main device 1101, there is an effect that the other party does not hear annoying sound such as the case where the call end information is transmitted through the modem.

Further, in this embodiment, since the PB signal for ending the call is different from the PB signal for dialing, the telephone line 11
Even when the exchange and the terminal connected to the destination of 06 receive the dial of the PB signal and perform the service, the malfunction does not occur.

Further, in the above first to third embodiments,
The PB signal is not limited to the combination of the high group frequency and the low group frequency as in this embodiment, but may be a combination of other frequencies. For example, the high group frequency and the low group frequency are 1/1
Even if it is set to 0, the same effect can be obtained. Since the PB sound in this case is outside the audible range, there is an effect that even the PB sound heard at the time of transmitting the control information cannot be heard in the first to third embodiments.

Further, PB tones other than the commonly used PB tones, such as those used in the first to third embodiments, are used for transmission of control information to connect to the end of the telephone line. It is possible to avoid malfunctions of exchanges and terminals as much as possible.
