And to the apparatus.

In recent years, telephones are emerging from the conventional telephone functions as simple telephone equipment, and more efficient and convenient functions using a microprocessor are being added to the telephones.

If you are provided with a telephone number guide service ('114' in Korea) in a normal telephone call, the user should speak with the guide and tell them the name or organization name of the telephone number they want to know. Search for the corresponding phone number and report the result as digital voice data. Accordingly, the user must note or remember the phone number, and after the telephone call ends, the user must call the phone number memorized or memorized again.

On the other hand, as another example, an extension number for each department, group or person in charge is designated in a public office or a large-scale workplace. In addition, a switch system for linking the extension number with the trunk line number is installed in most cases, and the switch system is provided with an automatic route selection service (ARS service) guiding each extension number. When an external user does not know the corresponding extension number, it is different for each device, but the extension number is guided sequentially by entering a specific function key, and the user enters the extension number if the desired extension number is recognized among the guided extension numbers. It must be entered sequentially.

However, according to such a conventional telephone, the following problem (s) occur.

In other words, the phone number recognized through the phone number guide service must be memorized or memorized by the user directly, causing inconvenience due to the memo process, and when remembering, there is a concern about forgetting.

In addition, when using the auto answering service, the department or group name that the user wants is automatically announced, but when the department or group name that is recognized does not match the department or group name that the user recognizes, the extension number is eventually determined through the guide. You should check. In this case, it is inconvenient to ask the guide for the extension number to be called or to input the corresponding trunk line number and the extension number sequentially after ending the call. And, even in this case, because the extension number must be memorized or memorized, the aforementioned inconvenience occurs.

Accordingly, the present invention is to solve such a problem (s), the object of the present invention is conveniently according to the voice signal (digital modulated voice signal or analog voice signal) guided by the voice service even if the user does not memorize or memorize The present invention provides an automatic dialing method for a telephone to dial a corresponding telephone number.

In addition, another object of the present invention is to provide an automatic dialing method of a telephone such that an extension number corresponding to the voice signal is automatically dialed even if the call is not interrupted according to the voice signal provided from the exchange.

Still another object of the present invention is to provide an automatic dialing device for a telephone to achieve the above objects.

The microprocessor 114 generally controls each component in the telephone. In particular, the microprocessor 114 stores the voice signal transmitted from the counterpart terminal in response to the input of the voice signal storage button in the memory 110, and the voice signal stored in the memory 110 in response to the input of the auto dialing button. After analyzing the corresponding telephone number, the DTMF generator 112 is controlled to generate a DTMF signal corresponding to the telephone number.

Referring to Figure 2 with respect to the operation of the present invention having such a configuration as follows.

First, the general operation of the telephone will be described. As the user presses a numeric button arranged on the operation panel 111 while holding the handset 106, the user dials the corresponding DTMF signal through the trunk line connection port 102. FIG. Calling the other subscriber by sending a call, and then, when a telephone line with the other subscriber is formed, the network control unit 107 processes the voice of the user inputted through the microphone for the call of the handset / handset 106 to access the trunk line connection port 102. By transmitting the voice signal transmitted from the other subscriber at the same time as the other subscriber through the receiver speaker of the handset / handset 106 to provide a call function between the subscribers.

At this time, the interface unit 104 matches the impedance with the counterpart terminal and interfaces the calling and signing functions. The network controller 107 amplifies the voice signal of the sender applied from the counterpart terminal and the user's voice signal applied from the transmitter / receiver 106 to a predetermined level and at the same time performs voice signal processing for side tones. Do this.

On the other hand, when the user wants to use the telephone number guide service call '114' (S1), the user first calls the guide. Here, if the user speaks the name of the company or department that he or she wants to know, the guide retrieves the corresponding phone number from the database and notifies the result (S2). It is output as voice data. At this time, as the user inputs the voice signal storage button in the operation panel 111 (S3), the microprocessor 114 switches to a mode that can store the telephone number.

Here, since the digital voice data reaches the user's telephone through the telephone line, since the digital voice data is in the form of a digitally modulated voice signal, the signal is demodulated in digital form by the voice signal demodulator in the voice signal processing unit 108 (S4). In accordance with the control of the microprocessor 114, it is temporarily stored in a predetermined area of the memory 110 (S5).

Then, after the user ends the call (S6), holding the handset 106 again (S7) and enters the automatic dialing button of the various function buttons arranged on the operation panel 111 (S8), the microprocessor 114 detects the voice signal temporarily stored in the memory 110 and the pre-stored voice signal samples and provides them to the voice signal determination unit 113 (S9). The voice signal determination unit 113 compares and analyzes the stored voice signal and the sample voice signal, detects a phone number corresponding to the corresponding voice signal (S10), and provides the same to the microprocessor 114. ) Controls the DTMF generator 112 to generate a DTMF signal corresponding to the telephone number (S11). Therefore, even if the user does not separately memorize or remember the corresponding phone number, the user can easily call the corresponding phone number (S12). The voice signal stored in the memory 110 is preferably set to maintain the memory state until a new voice signal is stored. At this time, if the user does not input the auto dialing button, the microprocessor 114 performs a general telephone function (S13).

On the other hand, if the user wants to call a specific person installed in a large corporate or public office to call the telephone number of the corresponding corporate or public office (S14), if an exchange is installed, the exchanger is preferentially connected. Here, if the user selects the department of the person who wants to know or waits for a certain time without inputting the department's extension number, the exchange informs each department name and the extension number sequentially, or is connected to the guide to inform the department name or person in charge. In other words, the guide searches for the corresponding extension number and directly informs the user of the extension number (S15). At this time, the notification of the extension number is notified to the user by an analog voice signal. At this time, as the user inputs the automatic dialing button in the operation panel 111 (S16), the microprocessor 114 switches to a mode that can store the telephone number.

Here, when the analog voice data reaches the user's telephone through the telephone line, the signal is converted into a digital form by the analog-to-digital converter in the voice signal processor 108 (S17), and then the microprocessor 114 Under the control, the memory 110 is temporarily stored in a predetermined area of the memory 110 (S18).

Thereafter, the microprocessor 114 detects the voice signal temporarily stored in the memory 110 and the pre-stored voice signal samples and provides them to the voice signal determination unit 113. The voice signal determination unit 113 compares and analyzes the stored voice signal and the sample voice signal, detects an extension number corresponding to the corresponding voice signal (S19), and provides the same to the microprocessor 114. ) Controls the DTMF generation unit 112 to generate a DTMF signal corresponding to the extension number (S20). Therefore, even if the user does not separately memorize or remember the corresponding extension number, the user can easily call the corresponding extension number (S21). The voice signal stored in the memory 110 is preferably set to maintain the memory state until a new voice signal is stored. At this time, if the user does not input the auto dialing button, the microprocessor 114 performs a general telephone function (S13).

Meanwhile, in the operation description of the present invention, such an operation may be realized by using only one automatic dialing button without separately providing a voice signal storing button and an automatic dialing button. That is, when the user inputs the auto dialing button, the user can store the voice signal correspondingly, and generate the DTMF signal corresponding to the voice signal even when the call is resumed or not terminated, thereby realizing the auto dialing. In addition, instead of configuring the auto dialing button separately, the existing * button or # button may be used.

As described above, although the specific embodiment (s) have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiment (s) but should be defined by the claims below and equivalents thereof.
