Abstract

PURPOSE:To prevent a cable telephone set, which is installed together on a host equipment side, from being erroneously off-hooked by acoustically announcing it from the host equipment that a radio telephony equipment is set in a holding state. CONSTITUTION:When a line is held during a call, a control signal is sent out from a control circuit 27 to a host equipment 1 by turning ON a holding switch 31 of a radio telephony equipment 2 and a control circuit 21 receiving this control signal sends out a signal to a holding circuit 11, sends out a tone and simultaneously changes over a holding tone monitor switch 15 to the holding circuit 11 side. Thus, the holding tone is sent out to a cable line 3, sent out through a transmitter 6 to the radio telephony equipment 2 for monitor, further passed through the holding tone monitor switch 15, which is changed over by the control circuit 21, amplified by an amplifier 13 and sounded from a loudspeaker 14 afterwards.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Field of Industrial Application) The present invention acoustically notifies users in the vicinity of the parent device that a portable wireless telephone is on hold. The present invention relates to a wireless telephone device.

(Prior Art) This type of wireless telephone device includes a parent device connected to a wired line and a portable wireless telephone connected to the parent device via a wireless line.

FIG. 2 is a block diagram showing a conventional parent device, which includes a parent device 1 connected to a wired line 3, and a wired telephone (branch telephone) 6 attached to the parent device 1. In this parent device 1, a transmitter 6 and a transmitting antenna 7 transmit a transmission signal to a wireless telephone (not shown), and a receiving antenna 8 and a receiver 9 receive a received signal from the wireless telephone. The audio signal from the wired line 3 becomes the modulation input of the transmitter 6 via the open-bottomed line switch 4 and the hybrid circuit 5, and the audio signal as the demodulated output of the receiver 9 passes through the hybrid circuit 5 and the line switch 4. The data is sent to the wired 1111 line 3 via the wired line 1111. Synthesizer 10 applies the carrier signal of the used channel to transmitter 6 and receiver 9. The intensifier 13 and the speaker 14 are sound output means for producing the tone W.

The CP C1iil path 12 is for automatically canceling the hold state, and its operation will be described later. Hold circuit 1
1 is a sound source that generates a hold tone. The control circuit 21 controls the parent device in an integrated manner. The AC power from the AC plug 17 is rectified and stabilized by the rectification stabilization circuit 18, and the resulting DC voltage is supplied to the parent device. It is connected to the charging terminal 20 through the charging terminal 20, from where it is supplied to the wireless telephone in order to charge its built-in rechargeable battery.

When such a radio telephone device shifts from a call state to a hold state, first, the radio telephone side transmits a control signal for placing the call state on hold to the parent device side.

Upon receiving this signal, the parent device sends the hold tone to the wireless telephone and the wired exit line.

In such conventional devices, although a hold tone is heard from the handset on the wireless telephone side, the master device only blinks the LED 34 to notify the hold state, as shown in Figure 2. Yes, it is not possible to confirm that the wireless telephone is on hold using the hold tone.

As a result, users in the vicinity of the parent device are only notified by the light emission, and the r(line telephone 16) connected in parallel with the wireless telephone device may be inadvertently taken off-hook.

On the other hand, this type of wireless telephone device has an automatic hold S cancellation function that divides the hold by jF4 and disconnects the call on the wireless telephone when the wired telephone 16 is off-hook while on hold, for the convenience of transfer operations and the like. Built-in.

Therefore, in the wireless telephone device having this eye-movement hold release function, when the wireless telephone user is in a hold state in which the user does not intend to transfer to the wired telephone 16, the other device being used is the G-line telephone.
6 went off-hook, there was a problem in which the call with the wireless telephone was disconnected.

(Problem that the invention attempts to solve) In this way, with conventional wireless telephone devices, when the parent device realizes that the device is on hold, the wired telephone attached to the parent device is accidentally taken off-hook. Then, there was a problem in that the hold was canceled by the ``removal function'' and the connection with the wireless telephone was disconnected.

This invention was made in view of two problems, the first of which is that when a wireless telephone is in a hold state, it notifies users in the vicinity of the main device of this fact by The purpose of this invention is to channel-in a wireless telephone device that can broadcast information widely.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a parent device that is connected to a wired line and has a built-in sound output means used for generating ringtones, etc.; a wireless telephone connected to the parent device via a wireless line, the wireless telephone transmits a hold state control signal to the parent device in response to a predetermined hold operation; In the wireless telephone device, the on-hold sound source is activated in response to the on-hold state control signal, and the on-hold sound is sent to both the wired line of sight and the wireless telephone. The present invention is characterized by further comprising means for supplying a hold sound from the hold sound source to the sound output means in response to a hold state control signal.

(Function) According to the present invention, when the wireless telephone is on hold, the parent device acoustically notifies the user of this fact, thereby eliminating the possibility of accidentally going off-hook of the wired telephone attached to the parent device.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of a wireless telephone device to which a hold system according to the present invention is applied.

As shown in the figure, this wireless telephone device has a wired 11
Connected to i1 line 3 11. The main device 1 includes a built-in sound output means (amplifier 13 and speaker 14) used to generate ringtones, etc., and a wireless telephone 2 connected to the main device 1 via a four-wire wireless wire. ing.

As will be described later, the wireless telephone 2 sends a holding state control signal to the parent device 1 in response to a predetermined held sample (by the switch 31), while the parent device sends a holding state control signal to the parent device 1. In response to the state control signal, a hold source (hold circuit 11) is activated, and the hold is sent to both the wired access line 3 and the wireless telephone 2.

That is, the basic configuration of this wireless telephone device is roughly explained as follows.

For example, when the line switch 4 is turned on, the signal transmitted from the wired port 3 is sent via the line switch 4 and the hybrid circuit 5.

On the other hand, the radio waves transmitted from the radio telephone 2 are received by the receiving antenna 8, and the receiving power is demodulated by the receiver. The demodulated signal is sent to the wired line 3 via the hybrid circuit 5 and line switch 4.

Synthesizer 10 outputs a carrier wave signal of a frequency corresponding to a wireless channel to transmitter 6 and receiver 9.

On the other hand, the radio telephone 2 similarly has a receiving antenna 22 and a receiver 23, and the demodulated output is output to a receiver 28. Further, the audio signal from the transmitter 30 is modulated by the transmitter 25, and radio waves are transmitted from the transmitting antenna 24.

Further, the speaker 29 is a sounder that emits a ringing tone when a call arrives.

Furthermore, 12 detects changes in the DC voltage of the wired line.
When the wired telephone 16, which is a lunch telephone, goes off-hook in the hold state, it detects a drop in line DC voltage, cancels the hold state, and then returns the wireless telephone to the on-footer state. 4 is in an open state).

In the above configuration, when a call is placed on hold, by turning on the hold switch 31 of the wireless telephone 2, a control signal from the control circuit 27 is sent to the parent device 1, and the control circuit 2 which receives the control signal is placed on hold. When the signal is sent to the circuit 11 and the hold tone is sent out, the hold monitor switch 15 is immediately switched to the hold circuit 11 side.

Then, the reserved piece is sent out through the hybrid circuit 5 to the G line 4 wire 3, and is also sent out from the hybrid circuit 5 through the transmitter 6 to the radio telephone 2 for monitoring.
Furthermore, it passes through the hold music monitor switch 15 which is switched by the control circuit 21, is amplified by the amplifier 13, and then is emitted from the speaker 14.

In this manner, in this embodiment, the hold tone can be easily confirmed on the parent device 1, so that it is possible to prevent the call from being put on hold due to the attached wired telephone 16 going off-hook.

〔Effect of the invention〕

As explained above, according to the present invention, in this type of radiotelephone device, even if the radiotelephone and the parent device are far apart, it is clearly shown to users in the vicinity of the parent device that the radiotelephone is on hold. This can prevent the attached wired telephone from being easily taken off-hook.

In addition, when implementing this method, the holding tone generation circuit can be used in common with the receiving circuit, and only a new switching circuit is required, so that there is no particular increase in cost.
