How to Automatically Send a Recording Time after Playing Messages on a Voice Mailbox Device

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a time automatic transmission method of recorded voice after a message is reproduced by a voice mailing system (VMS), and more particularly, .

Conventionally, in order to know the recorded time when listening to a message recorded in the voice mailbox device, the recording time can be confirmed only by inputting a predetermined key during listening to a message or listening to the message.

That is, the conventional recording time confirmation method as described above has a problem in that it can be confirmed only by a predetermined key input. Also, there is no method of re-confirming the recording time by displaying the recording time on a display window (LCD).

Accordingly, it is an object of the present invention to provide a method for voice transmission of a recorded time automatically after a message is received from a voice mail apparatus.

It is another object of the present invention to provide a method for displaying a time automatically recorded after a message of a voice mailbox device is displayed on a display window.

A method of automatically transmitting a recording time of a voice mailbox apparatus operated in conjunction with a key telephone for achieving the above objects comprises the steps of: receiving a mailbox number, a mailbox number and a password from a subscriber terminal entering the voice mailbox apparatus; Detecting an input of a secret key corresponding to the received password and checking whether there is a recorded message in the mailbox; and transmitting the recorded message when the recorded message is detected, And transmitting the voice recording time to the subscriber terminal; and transmitting the voice recording time when the subscriber terminal is the key telephone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

In order to implement the present invention, the main key 1 of the key phone system and the voice mail box 2 are installed to be interlocked with each other via a DLI (digital line interface) card.

Referring to FIG. 1, the controller 111 controls the overall operation of the key phone system to control call switching and provide various services to the user. ROM 112 stores the program and initial service data of the controller 111 for performing basic call and various functions. The RAM 113 temporarily stores data generated by the controller 111 during program execution. The switching circuit 114 switches various signals under the control of the control unit 111. The subscriber circuit 115 provides a call current to an extension terminal (a key telephone or an ordinary telephone) under the control of the controller 111 and at the same time, interfaces signals between the subscriber telephone and the switching circuit 114. The ring generator 116 generates a ring signal and supplies it to the subscriber circuit 115. The CO line circuit 117 seizures the CO line under the control of the control unit 111 to form a CO line loop and interfaces the signal between the CO line and the switching circuit 114. Here, the CO line CO refers to a line connecting the CO line circuit 117 and the public switching center. The tone generator 118 generates various tone signals under the control of the controller 111 and outputs the generated tone signals to the switching circuit 114. The DTMF receiver 119 analyzes the DTMF signal input from the switching circuit 114, converts the DTMF signal into digital data, and outputs the digital data to the controller 111. The DTMF signal input from the switching circuit 114 to the DTMF receiver 119 is a telephone number generated by the trunk line subscriber or a telephone number generated by an extension subscriber. The DTMF transmitter 120 converts the digital data output from the controller 111 into a DTMF signal and outputs the DTMF signal to the switching circuit 114. Here, the DTMF signal output from the DTMF transmitter 120 becomes a telephone number of a subscriber who is a subscriber when the subscriber side calls the subscriber.

The voice mail box device 2 is connected to the subscriber circuit 115 of the host 2 and reproduces a voice message received from the key phone main unit 1 under the control of the controller 111 or a recorded voice message, do.

First, the codec 121 connected to the subscriber circuit 115 converts an analog signal into a digitized PCM (pulse code modulation) signal or converts a digitized PCM signal into an analog signal. The adaptive differential PCM (ADPCM) 122 converts a voice signal (PCM signal) transmitted to a 32K ADPCM signal or a 32K ADPCM signal to a PCM to reduce the capacity of a storage device (DISK) for storing voice. The signal conversion method of the ADPCM is a technique of reducing the number of bits of a coded voice signal as one of digital coding methods of voice signals. In other words, a prediction signal of speech is generated in the encoder, and this is compared with the actual input signal, and the difference is encoded.

The second controller 123 performs DTMF detection and tone detection functions received from the keyphone main unit 1 and performs data communication with the RAM 126. The common memory 124 temporarily stores data transmitted and received between the RAM 126 and the second controller 123.

The first control unit 125 controls and adjusts the overall operation of the voice mail apparatus 2. The RAM 126 temporarily stores voice data and various data for real-time processing. The disc control unit 127 controls the disc 128, and the disc 128 stores compressed audio data. In accordance with the present invention, the disc 128 stores voice messages received from an external subscriber and also stores voice messages to be transmitted by the internal subscriber. It also manages a mailbox database with a large number of information about the message.

Also, the voice mail apparatus 2 is connected to the subscriber circuit 115 through a voice path and a data path, and commands of the controller 111 are transmitted to the voice mail apparatus through the data communication path . As mentioned above, the presence of a separate data communication path is called Outband Signaling, while transmission and reception of commands to and from DTMF using a voice transmission path without a separate line is called Inband sigalling.

In addition, the key telephone according to the present invention includes a message listening button having a shortening function for listening to a message, and a display window for displaying various operation states. Therefore, when listening to the message, the subscriber can use the message listening button, enter the designated number if necessary, and enter the voice mailbox device to listen to the message. Also, a method of entering a voice mailbox apparatus 2 at the designated number and listening to a message is also easy in a general telephone.

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

FIG. 2 is a flowchart illustrating an operation for receiving a voice message according to an exemplary embodiment of the present invention and recording the received voice message to a corresponding mailbox of the voice mail apparatus 2. The operation to be described below is the first control unit of the voice mail apparatus 2 and shows a process of receiving a voice message from an external subscriber and recording the voice message.

First, the first controller 125 detects entry of the external subscriber into the mailbox in step 211. [ That is, the external subscriber has failed to connect with the extension to which the call was made, and enters the mailbox of the voice mailbox device 2 with a designated key input to leave a voice message in the mailbox assigned to the extension.

In step 213, the first controller 125 determines whether a recording key is input. If the recording key is input, the first controller 125 proceeds to step 215. If the recording key is not input, the first controller 125 proceeds to step 221 and performs a corresponding function.

The first controller 121 proceeding to step 215 records the voice message received from the external subscriber. After completion of the recording, the first controller 125 proceeds to step 217 and reads time (month, day, hour, minute) from the built-in clock circuit in the first controller 125, And stores it in the recording time area.

In step 219, the first controller 215 stores the voice data and the mailbox database on the disk 128, and ends the program storing the time for the voice message.

An example of the mailbox database is shown in Table 1 below.

[Table 1]

Mailbox number Message type Message recording time Message Playback Time Message sending time Message deletion time ...

The mailbox database shown in Table 1 is managed in correspondence with each mailbox and stores a plurality of pieces of information about voice messages recorded in the voice mailbox unit 2. [

An example will be described with reference to Table 1. A message type area in which a property of a message (whether it is a received message or a stored message) can be designated, a message recording time area storing a recorded time of the received message, A playback time zone for storing the time at which the recorded message is played back, a transmission time zone for storing the reservation time of the message to be transmitted, and a deletion time zone for storing the setting time for automatically deleting the message recorded in the mailbox .

FIG. 3 is a flow chart illustrating an operation for voice transmission and display of a recording time after reproducing a recorded voice message according to an exemplary embodiment of the present invention.

The operation to be described below is a method of inputting a designated number and entering a voice mail box device 2 and listening to a message, which is a method that can be commonly used in a key telephone or a general telephone.

First, the first controller 125 detects the entry of the terminal (extension terminal or external terminal) into the voice mailbox apparatus in step 311. The entry into the voicemail box device 2 is performed by inputting the designated number. The first controller 125 receives the mailbox number from the terminal in step 313 and receives the password in step 315.

When the password corresponding to the mailbox number is detected, the first controller 125 transmits the first guidance message to the terminal in step 317. [ Here, the first guidance message is a message informing the user of the mailbox service of the voice mailbox device or the selection number for each service.

In step 319, the first controller 125 detects a play key input from the terminal. Upon detecting the play key input, the first controller 125 checks if there is a recorded message corresponding to the mailbox number in step 321. [

At this time, if there is a recorded message, the first controller 125 proceeds to step 323. If there is no recorded message, the first controller 125 proceeds to step 335 to transmit a third announcement message, End this program to send. Here, the third guidance message is a message for notifying the terminal that there is no recorded message corresponding to the mailbox. For example, there may be 'no recorded messages'.

The first controller 125 proceeds to step 323 and transmits the recorded message to the terminal. In step 325, the first controller 125 checks whether the recorded message is transmitted. At this time, if the message sending end is checked, the first controller 125 proceeds to step 327. If the message sending end is not checked, the first controller 125 returns to step 323 to continue sending the message. The first controller 125 proceeds to step 327 to automatically transmit the recording time of the message to the terminal.

Hereinafter, a method of transmitting the recording time by voice will be briefly described. First, the first controller 125 reads the time at which the message is recorded in the mailbox database corresponding to the transmitted message. Based on the time data, audio data that has been formatted in advance is read from the disk 128 and transmitted. For example, voice data ('received at' -month-day-hour-minute ') for a character other than the number corresponding to the priority time is formatted in advance and stored in the disk 128. Then, the voice data for the number is stored separately, and the voice data for the corresponding number is interposed between the formatted voice and voice data every time the message is reproduced.

In step 329, the first controller 125 determines whether the terminal is a key telephone. At this time, if the terminal is inspected by the key telephone, the first controller 125 proceeds to step 333 and displays the recording time on the display window of the key telephone. Wherein the data on the recording time is provided to the key telephone through a key telephone main unit and a data communication path connected to the voice mail apparatus.

On the other hand, if the terminal is not inspected by the key telephone, that is, if it is inspected by the ordinary telephone, the first controller 125 transmits a second guidance message to the terminal in step 331, and returns to step 321 to check if there is any recorded message The program in step 321 or less is re-executed. Here, the second guidance message is a message informing the subscriber that the recorded message is transmitted after the transmitted message. For example, it could be 'Next message'.

FIG. 4 is a flowchart illustrating an operation of voice transmission and display of voice recording after voice message reproduction according to another embodiment of the present invention.

The operation to be described below is an operation for automatically transmitting and displaying the recording time in a key telephone provided with a quick button for listening to a message. That is, the message listening button of the key telephone is used to directly enter the message playback.

First, the first controller 125 detects an input of a message listening button from the key telephone in step 411. In step 413, the first controller 125 determines whether there is a recorded message. At this time, if there is the recorded message, the first controller 125 proceeds to step 415. If there is no recorded message, the first controller 125 proceeds to step 425 to transmit the third guidance message to the key phone, And terminates. An example of the third guidance message may be 'no recorded message'.

The first controller 125 proceeds to step 415 and reproduces the recorded message to the key telephone. In step 417, the first control unit 125 checks the transmission of the message. At this time, if the message sending end is checked, the first controller 125 proceeds to step 419. If the message sending end is not checked, the first controller 125 continues to step 415 for sending the message.

Upon detecting the end of the message transmission, the first controller 125, which has proceeded to step 419, automatically transmits the recording time of the message to the key telephone. In step 421, the first controller 125 recognizes that the terminal to which the key is input is the key telephone, and displays the recording time on the display window of the key telephone. The recognition may be recognized in accordance with a protocol transmitted / received through the data communication path of the key telephone main unit 1 and the key telephone period simultaneously with the input of the message listening button of the key telephone. Here, the data on the recording time is provided to the key telephone through the data communication path connected to the key telephone main unit and the voice mail apparatus in the voice mail apparatus.

In step 423, the first controller 125 transmits a second voice message to the key telephone. In step 413, the controller 125 determines whether there is a recorded message. Here, an example of the second guidance message may be 'next message' or the like.

As described above, according to the present invention, the recording time of the message recorded in the voice mailbox device is automatically transmitted, so that the recording time can be easily confirmed. Further, the recording time is displayed on the display window of the key telephone, so that it is easy to reconfirm the recording time.
