[Conventional technology]

The hold feature on your phone allows you to keep the active line on hold and call other lines from your phone. This is a function that allows calls to be made between telephones or between telephones, so-called home telephony. For residential phones such as telephones, an extension (line) may be shared between multiple phones, or This is an important function when a single telephone line is used in common by multiple telephones. ing.

0003 Traditionally, this hold function was added to the phone case or handset in the form of a hold button. and you want to put an active line on hold to call someone inside. If you press the hold button once and then press the hold button again to cancel the hold state and return to the call state, The user had to press the hold button every time. This allows you to make phone calls while doing work. The same thing applies when you ask the other person to wait a little while you are talking.

0004

[Problem that the idea aims to solve]

However, operating the hold button while doing work is extremely troublesome. . In particular, the hold button is built into the handset rather than the phone housing. If the handset is normally held against your ear, move it away from the transmitting/receiving position and press the hold button. must be operated after confirming its location. In addition, the so-called base unit and wireless In the case of a wireless phone consisting of a handset connected by Since it does not have a workstation switch, to release the hold state, use the handheld device like the base device. It is not enough to simply lift the set by hand; you must always operate the hold button. .

[0005] Therefore, the purpose of this invention is to provide wireless telephones etc. that do not have a hook switch. A phone hold release device that allows you to release your phone from hold status without pressing the hold button. Our goal is to provide the following.

[0006]

[Means to solve the problem]

The telephone hold release device according to the present invention detects that the speaker has grabbed the handset. A detection signal is output from the touch sensor section and the touch sensor section is output while on hold. This configuration also includes a control section that returns to the talking state when the communication occurs.

[0007]

[Effect]

If the speaker grabs the handset while on hold, the touch sensor detects this. The control unit automatically returns the telephone to a talking state. Therefore, the hook A wire that does not have a switch and therefore does not return to a talking state just by picking up the handset. Even if you are using a telephone that does not have a telephone number, you do not have to go to the trouble of pressing the hold button in a busy environment. do not have.

【Example】

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0009] In Figure 1, telephone line L is connected to network control unit (NCU) 1 in the base unit. Ru. The line control unit 1 is a device that controls the telephone exchange network, and when starting up the central office exchange and transmitting Sending selection signals (dial pulses, etc.), detecting ringing signals during reception, and Forms DC circuits, etc. 2 constitutes a telephone hold control device together with a voice recognition device 3. It is a control unit mainly based on the CPU that constitutes 11 (FIG. 2). 4 was provided in this handset 11 A transmitter (microphone), 5 a receiver (speaker), 6 an operation section, and 7 a touch sensor. This is the sensor department. The operation unit 6 includes switches such as a dial operation button 8 and a hold button 9. and indicator lamps. For convenience, FIG. 1 shows the network control device 1 of the base unit and the control unit of the slave unit. 2 is depicted as being directly connected, but wireless transmission and reception is not actually shown. connected via a communication device, etc.

0010 The voice recognition device 3 uses registered held voice whose frequency has been analyzed and features have been extracted in advance. In comparison with the speaker voice pattern and the registered held voice pattern, When a match is detected and the pattern matching between the two is achieved, a held voice detection signal is output. Strengthen. The hold voice patterns handled here include, for example, "Please wait a moment." There are multiple types of words. To increase the speech recognition rate of these words, a speech recognition device Several standard patterns are registered in the dictionary No. 3. Also, general use is possible. In order to make this possible, the speech recognition device 3 supports unspecified speakers as the speaker condition and utterance condition as the speech condition. It is now possible to recognize continuous vocalizations.

[0011] The touch sensor unit 7 is a circuit that detects release of the hold state, and is a circuit that detects release of the hold state. Touch electrodes 7a and 7b are exposed on the back of the grip part and installed at intervals, and both The change in capacitance between the electrodes indicates that the handle of the handset 8 has been touched or gripped. It consists of a high frequency bridge circuit that detects the

0012 FIG. 2 shows a control flow for setting hold and canceling hold.

[0013] First, a ringing signal arrives through telephone line L due to a call from the other party, When the hook switch of the base unit operates (that is, on-hook), a DC circuit is established between the base station and the other station. is formed and the call is in progress (step). Here, the subscriber is, for example, a slave device. Hold the handset 11 in your hand and bring the mouthpiece and earpiece close to your mouth and ear. Let's have a conversation.

[0014] Next, the control by the CPU transmits the transmitted voice through the transmitter 4 and the voice recognition device 3. Starts the process of checking whether or not held audio is detected from within (step) . At this point, when the speaker speaks the preset words such as "Please wait a moment", , the speech recognition device 3 converts this speaker's speech pattern into a reserved speech pattern registered in the dictionary. A held voice detection signal is output based on a match. This allows C.P. U immediately disconnects the handset 4 and handset 5 from the network control device 1 and puts the phone on hold. (step). At this time, the CPU also recognizes that the hold function is working. To display confirmation, turn on the display lamp (hold lamp) belonging to the hold button. (step). Also, the time until the speaker places the handset 11 on the housing or tabletop. To ensure time, a cancellation timer is set (step).

[0015] Subsequently, the CPU receives the data from the touch sensor section 7 until a predetermined timer period elapses. Input is prohibited (step), and when the time is up, this touch sensor input Remove the ban (step). Then return to the step and the pending state is cleared. wait for it to be removed (step).

[0016] At this point, when the speaker picks up the handset to start the conversation again, the touch electrode The capacitance between 7a and 7b changes, causing the high frequency bridge circuit to become unbalanced and causing a touch. A detection signal is output from the sensor section 7. In response to this, the CPU of the control unit 2 It is determined that the detention status should be lifted. That is, the detection signal from the touch sensor section 7 is When input, the judgment of the step becomes Yes, and the CPU starts the cancellation timer. At the same time as resetting, the hold lamp turns off (step) and returns to the call state. (step). That is, the transmitter 4 and the receiver 5 are connected to the network control device 1, and a telephone call is made. becomes possible. In addition, in this embodiment, the release of this hold state is performed by the touch sensor. In addition to inputting a detection signal from the server, you can also press the hold button 9 as usual. It can also be done by

[0017] In the above embodiment, the explanation was given using a wireless telephone as an example, but the above-mentioned hold setting and The release device can also be applied to ordinary telephones. Also, the configuration of the touch sensor part is In addition to the above-mentioned non-contact type switch, a dominant contact type switch can also be used.

[0018]

[Effect of the idea]

As explained above, according to the present invention, if the speaker grabs the handset while on hold, , which immediately returns the telephone to the talking state. Therefore, the handset Even if it is a wireless phone that does not return to talking mode just by holding it, do not bother to use it. There is no need to operate the hold button, which is very convenient.
