BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private exchange, and more particularly, to a message weighting method and apparatus using a telephone ring tone capable of performing a message wait function without attaching a separate message weight lamp to a telephone of an extension subscriber.

In general, a private exchange installed in a hotel or the like requires a message weight function that notifies the guest that the call is received through the guest's phone when the guest is away. In the conventional private switching system, the message weighting method installs a separate message weight lamp on the subscriber's telephone to reverse the polarity of the extension to light the message weight lamp to perform the message weighting function, thereby informing the subscribers of the incoming call. As a result, it was difficult to modify the phone, and it was difficult to purchase a phone equipped with the corresponding message weight function.

In addition, logic for polarity reversal should be installed in the private telephone, and in some cases, logic and power supply circuit for supplying high voltage of 80 volts to the telephone should be added. A separate message weight lamp was attached.

When the message weight lamp is lit on the telephone, the corresponding station subscriber picks up the telephone and calls the relay station or responds to the message weight using a code.

When a message weight call is generated and the control unit commands the subscriber to reverse the polarity of the power supply, the subscriber circuit activates the polarity inversion relay to invert the polarity of the power supplied to the telephone, thereby turning on the light emitting diode (LED) attached to the telephone. If the message weight call is not present, the message weight lamp is 'off' by not reversing the power polarity.

However, when using such a method, it is difficult to purchase a phone for performing the corresponding message weight function, and a circuit for inverting the polarity of power is required. When using a conventional phone, the message weight lamp is installed by disassembling the phone. Not only is it inconvenient to modify many extension telephones, but the user has to monitor the telephone at all times and watch for the message weight lamp to turn on.

The present invention has been made to solve the problems of the prior art as described above, so that the message weight function can be performed without the polarity inversion to the subscriber to perform the message weight function without modifying the internal circuit of the general CPU The purpose is not only to reduce the production cost of the product but also to allow the user to audibly check the status of the message weight through ring ringtones without having to constantly monitor the message weight lamp.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the message weight device of the present invention includes a control unit 1, a relay station 6, a recording device unit 8, a subscriber control unit 9, a subscriber circuit unit 10, a power supply unit 11, and a ring. The signal generator 12 is provided. The control unit 1 also includes a CPU 2, a memory unit 3, a switching unit 4, a tone control unit 5, and a message interface unit 7.

The relay station 6 outputs the message weight request information and the message weight cancellation information to the message interface unit 7 side. The message interface unit 7 collects the message weight request information and the message weight cancellation information from the relay station 6 and transmits the message weight request information to the CPU 2, and transmits the message weight response code from the subscriber controller 9 to the CPU ( 2), and transmits the message weight ring sending command and the message weight canceling command applied from the CPU 2 to the subscriber control unit 9 side. The CPU 2 transmits the message request subscriber information (the message weight to the subscriber) to the corresponding subscriber according to the message weight request information applied from the message interface unit 7 and the message weight request information applied from the switching unit 4. The requesting party's telephone number) in the memory unit 3 and outputs a message weighting ring sending command for informing the message weight status to the subscriber circuit unit 10 via the message interface unit 7 and the subscriber control unit 9; The message request subscriber information for the corresponding subscriber registered in the memory section 3 according to the message weight response code applied from the subscriber circuit section 10 via the subscriber control section 9 and the message interface section 7. Call the subscriber corresponding to the message and according to the message weight cancellation information authorized from the message interface unit 7; D) Delete the message request subscriber information for the corresponding subscribers from the memory unit 3, and output a message weight cancel command to the message interface unit 7, the tone control unit 5, the recording unit 8 and the ring. The operation of the signal generator 12 is controlled, and the switching operation of the switching unit 4 is controlled.

The memory unit 3 records or deletes the message request subscriber information for the subscribers under the control of the CPU 2. The subscriber number is recorded in the telephone number sorting table as shown in FIG. The message request subscriber information of the extension subscribers recorded in the above is recorded in the message weight request table as shown in FIG. 2a. Up to eight message request subscriber information is recorded for each subscriber, and under the control of the CPU 2 The message request subscriber information recorded in the message weight request table is deleted.

In addition, the switching unit 4 is connected to the trunk line, the CPU 2, the tone control unit 5, the repeater 6, the recording device unit 8, and the subscriber control unit 9, and the CPU 2 Connect the CO line to the relay station 6 or the subscriber control unit 9 to form a call path under the control of the control unit, and transmit the tone signal applied from the tone control unit 5 to the subscriber control unit 9 or the CO line. The voice signal transmitted from the recording device unit 8 is transmitted to the trunk line or subscriber control unit 9 side. The subscriber control unit 9 transmits the tone signal and the guide voice signal applied from the switching unit 4 to the subscriber circuit unit 10 side, and transmits the call voice signal input / output between the switching unit 4 and the subscriber circuit unit 10. And transmits the message weighting ring sending command and the message weight canceling command applied from the CPU 2 through the message interface unit 7 to the subscriber circuit unit 10, and sends the message weight response code from the subscriber circuit unit 10 to the message. It transfers to the CPU 2 side via the interface unit 7. The subscriber circuit unit 10 accommodates a plurality of subscribers, and is driven from the ring signal generation unit 12 by driving the relay 13 at predetermined time intervals according to a message weight ring transmission command applied from the subscriber controller 9. The ring signal is output to the extension subscriber's phone at predetermined intervals to inform the subscribers of the message weight status. When the extension subscriber's phone which outputs the ring signal is off-hook, the tone signal and guide voice applied through the subscriber control unit 9 are output. If the message weight response code is applied from the extension subscriber's phone after outputting the signal to the subscriber's phone side, the message weight response code is output to the subscriber control unit 9, and the message weight cancel command from the subscriber control unit 9 is output. When applied, the ring signal that was output to the telephone side of the subscriber station by stopping the driving of the relay 13 By stopping the output to stop dispensing of the ring signal to inform the message weight state. On the other hand, the power supply section 11 supplies the operating power to each circuit section.

Referring to the effects of the present invention configured as described above are as follows. First, the operator of the relay station 6 receives the message weight request for the subscriber from the subscriber connected through the switching unit 4 and presses the message weight button installed on the relay station 6 to request the message weight. If the subscriber number that registered the message weight and the message weight request subscriber information (the other subscriber number that requested the message weight request to the subscriber) are entered, the relay station 6 requests the corresponding subscriber number and the message weight request. The message weight request information including the subscriber information is output to the message interface unit 7 side. At this time, the message interface unit 7 collects the message weight request information including the subscriber number and the message weight request subscriber information applied from the relay station 6 and sends the message weight request information to the CPU 2 side.

Accordingly, the CPU 2 checks whether the corresponding subscriber number received from the message interface unit 7 is recorded in the memory unit 3, and if the corresponding subscriber number is recorded, the message interface unit 7 The message weight subscriber information received from the program is recorded in the memory unit 3, and a message weight ring sending command is sent to the subscriber control unit 9 via the message interface unit 7 in order to inform the message weight state.

Subsequently, the subscriber control unit 9 outputs the message weight ring sending command authorized from the CPU 2 to the subscriber circuit unit 10 side, and the subscriber circuit unit 10 transmits the message weight ring sending command received from the subscriber control unit 9 to the subscriber. Accordingly, the relay 13 is driven at predetermined time intervals to output the ring signal applied from the ring signal generation unit 12 to the relay 13 at predetermined time intervals to inform the subscribers of the message weight status. If the ring signal is sent out for a given time, the ring signal output is stopped, and the ring signal is output to the telephone subscriber of the station subscriber in such a manner that the ring signal is output again after a predetermined time delay. That is, the subscriber circuit unit 10 notifies the subscribers of the message weight state by varying the output period of the ring signal so as to be distinguished from the general ring tone. In addition, if you want to cancel the message weight in the relay station 6, after pressing the message weight cancel button, enter the extension number for canceling the message weight, message weight cancellation information including the corresponding subscriber number is a message It is applied to the CPU 2 side via the interface unit 7, and the CPU 2 deletes the message weight subscriber information corresponding to the extension subscriber number received through the message interface unit 7 from the memory unit 3. And the subscriber controller 9 applies the message weight cancel command to the subscriber controller 9 so that the subscriber controller 9 applies the corresponding message weight cancel command to the subscriber circuit unit 10 side. Stop the output of the ring signal to indicate the message weight status.

If the station subscriber listens to the ring signal and the subscriber subscriber phone is off-hook while the message weight is registered, the CPU 2 controls the tone control unit 5 or the recording device unit 8 to send the message weight to the corresponding subscriber. A specific tone signal of the tone control unit 5 or a guide sound signal recorded in the recording device unit 8 to inform that registration has been made through the switching unit 4, the subscriber control unit 9, and the subscriber circuit unit 10; Since the station is sent to the telephone side of the extension subscriber, the extension subscriber recognizes that the message weight is registered by listening to a specific tone or guide voice and dials the message weight response code. When the message weight response code is dialed, the subscriber control unit 9 collects the message weight response code applied from the subscriber circuit unit 10 and inputs it to the CPU 2 via the message interface unit 7. ) Is a message request subscriber information recorded in the extension number of the subscriber if the message weight is registered by searching whether the number of the extension subscriber who inputs the corresponding message weight response code is registered in the memory unit 3 and the message weight is registered. The subscriber's number which has requested a message weight to the subscriber is read from the memory unit 3 and the tone control unit 5 is controlled to send the corresponding dial tone signal to the trunk line via the switching unit 4 to automatically make a call. When the called party or the relay station 6 is called, the called party or the relay station 6 responds. The caller then speaks to the extension and sends a message to the subscriber.

In addition, the general subscriber connected through the CO line off-hooks the telephone to request a message weight to the subscriber, and then dials and has his / her telephone number including the subscriber's number in a state in which a call path is formed in the switching unit 4. When dialing the message weight request information, the CPU 2 receives the corresponding message weight request information through the switching unit 4 and retrieves the corresponding subscriber number from the memory unit 3 so that the corresponding subscriber number is stored in the memory unit 3. ), The subscriber's telephone number that has requested the message subscribers to the extension subscriber is registered in the memory unit 3 as the message request subscriber information, and then the message weight ring sending command is sent to the message interface unit 7 and the subscriber controller 9; Outputs to the subscriber circuit unit 10 via the subscriber circuit unit 10, and the subscriber circuit unit 10 receives the message way authorized from the subscriber controller 9; In response to the ring transmission command, the relay 13 is driven at predetermined time intervals to output a ring signal applied from the ring signal generation unit 12 to the relay 13 at predetermined time intervals to the telephone side of the corresponding station subscriber to display the message weight state. Notify extension subscribers. At this time, the extension subscriber's response method is performed in the same manner as described above.

As described above, according to the present invention, when the message weight is registered, the subscriber is notified of the message weight status by outputting a ring signal to the subscriber, so that the subscriber telephone does not need to have a message weight lamp. There is no need to have a polarity inversion circuit in the circuit part, which can greatly reduce the production cost of the equipment, and it is possible to use the existing telephone as it is without modifying the internal circuit of the telephone and to monitor the message weight lamp by the user. The user can conveniently use the message weight function by listening to the ring tone and hearing the message weight status.
