Abstract

A technique for anti-harassment telephone adds necessary hardware circuit and control software based on the existing telephone set circuit. The telephone set equiped with this technique will not ring immediately when the call is coming as the anti-harassing function is on, but it will decide to ring or not according to the checked result of the inputted identify code of caller to prevent the undired call harassing the work or rest of the phone set owner.

Description

Barassment preventing telephone technology

Affiliated technical field: electronic technology

Background technology: the telephone circuit of existing telephone technology mainly comprises: shake bell circuit, speaking circuit, dial-up circuit, display circuit etc.Its groundwork process is: when phone arrived, shake bell signal made shake bell circuit working, promptly sends jingle bell, behind the machine master off-hook, and speaking circuit work, finishing once, conversation back on-hook finishes.When calling, first off-hook, dial-up circuit work in button, dial the number is passed to switch by local telephone, is switched to the subscriber phone of wanting by switching network, and sends shake bell signal to this phone.Behind the other side's off-hook, finish conversation by speaking circuit.

The imperfection part of existing telephone technology is: as long as no matter be when who dials certain phone, just this telephone ringer sound, until machine master off-hook.Can't refuse the harassing and wrecking of harassing call.

The purpose of innovation and creation: stop anyly to have a mind to or harassing call unintentionally.

Press technology side: on the basis of the technology of existing telephone circuit, add DTMF/P decoding circuit, microprocessor control circuit, voice warning circuit in circuit.The password that cooperates telephone set to take charge and set earlier adopts checking identity or password earlier, examine by after the method for jingle bell again, realize the purpose of anti-harassing and wrecking.Promptly when phone arrives, the first ring that do not allow, but under the control of microprocessor (MPU) the simulation off-hook, the voice suggestion person of dialing inputs one group of machine password of informing earlier (or the information that should know the machine master) of taking charge, after microprocessor is decoded by the DTMF/P decoding circuit, whether the password of the checking person of dialing input determines jingle bell, this call of prompting telephone set master again.If password is not right, jingle bell not then, and hang up this phone.

The working method that phone is transferred to is identical with plain old telephone.

This function can be set in certain period effectively (as 23:00 to 6:00) by the machine master, also can continuously effective, but also this function of temporary close.

Beneficial effect: because this technology is the increase that relies on telephone set self function, telephone-switching network is not increased requirement, therefore this technology is applicable to existing telephone and mobile phone communication switching network fully, can stop any type of making nuisance calls fully, the quality that improves people's work, life and have a rest.This technology is to the once improvement of telephone communication technology and perfect.

Description of drawings: Fig. 1: wired Barassment preventing telephone circuit block diagram; Fig. 2: phone is prevented the disturbance device circuit block diagram; Fig. 3: Barassment preventing telephone technology workflow diagram.

Embodiment: the Barassment preventing telephone technology workflow diagram as shown in Figure 3.When phone arrives, elder generation is jingle bell not, but under the control of microprocessor (MPU) the simulation off-hook, by sound circuit prompting the other side reader take charge one group of password of informing earlier or one group of information should knowing the machine master, such as machine master age, machine main building number, notify from a phone call number etc.After treating that the other side imports, (MPU) checks by microprocessor, and input is jingle bell just correctly, waits that standby is main to receive calls.Otherwise this phone is refused in the simulation on-hook.

This technology can be applied in the daily electronic product with three kinds of forms at least, that is: landline telephone, mobile phone, the anti-disturbance device of phone.

Implementing measure in the landline telephone: shown in the wired Barassment preventing telephone circuit block diagram of accompanying drawing 1--.The part that frame of broken lines is lived among the figure is for increasing part newly.After " preventing harassing and wrecking " function is effective, " on-off control circuit " promptly is in off-state, have this moment phone to arrive, phone shake bell does not ring, but after " shake bell testing circuit " detects shake bell signal, MPU control " interface circuit " simulation off-hook, and control " voice warning circuit " output information, such as " time of having a rest, please dial again later; as be in a hurry, please input password " (maybe please import confirmations such as owner's age or machine master beeper number).Behind " DTMF/P decoding circuit " reception the other side dial-up, compare with the password that deposits MPU in advance in, meet back MPU control control " on-off control circuit " connection " speaking circuit ", and control " shaking the bell circuit " jingle bell, prompting machine master answers the call.If password is examined failure, then hang up the telephone.

When function was closed, " on-off control circuit " was in on-state when being in non-time of having a rest or " anti-harassing and wrecking ", and this telephone set is equally worked with plain old telephone.

Phone is prevented disturbance device: shown in the anti-disturbance device circuit block diagram of Fig. 2-phone." keyboard and display circuit " is used for setting code and setting-up time.When entering after time of having a rest or anti-harassing and wrecking function open by force, " interface control circuit " promptly disconnects being connected of local telephone and telephone set.Phone (shake bell signal) is being arranged when arriving, " shake bell testing circuit " detects signal and notifies MPU, MPU control " interface control circuit " simulation off-hook, information is sent in control " voice warning circuit " simultaneously, such as " time of having a rest; please dial again later, as be in a hurry, please input password " (maybe please import confirmations such as owner's age).Behind " DTMF/P decoding circuit " reception the other side dial-up, compare, meet back MPU control " interface control circuit " and connect local telephone and telephone set, control " shaking the bell circuit " jingle bell simultaneously, the announcement machine master with the password that deposits MPU in advance in.If password is examined failure, then hang up the telephone.

When function was closed, " interface control circuit " was in on-state when being in non-time of having a rest or " anti-harassing and wrecking ", and telephone set inserts the local network operate as normal.

Implementing measure in mobile phone: in mobile phone, only need increase the DTMF/P decoding function in DSP, hardware components need not increase other circuit again, and mainly increases module on Control Software.Under the control of digital signal processor (DSP), realize: simulation off-hook, voice suggestion, cryptographic core equity function.Only allow important and urgent telephone rings to be implemented in the time of having a rest, prevent the meaningless machine of making nuisance calls master's effect.

Claims

1. one kind is passed through on the basis of existing telephone technology, increase partial function circuit and control circuit, adopt checking incoming person's identity or password earlier, examine by after the method for jingle bell again, realize the telephony of anti-harassing and wrecking, it is characterized in that when having phone to arrive not jingle bell immediately, but after prompting the other side input is used to examine the password of its identity, whether according to circumstances determine jingle bell again, to stop inappropriate machine master's that makes nuisance calls work and rest.

2. all utilize the method for Barassment preventing telephone technology of right 1 and electronic products such as the anti-disturbance device of the landline telephone, mobile phone and the phone that form.
