Description

Dialing signal transmission control method of telephone terminal device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling dialing signal transmission of a telephone terminal device, and more particularly, to a method for controlling dialing signal transmission of a telephone terminal device for quickly transmitting a dialing signal corresponding to a plurality of telephone numbers.

In general, in order to talk to the other party using a wired or wireless telephone terminal device, the telephone number of the other party must be dialed using a key on a key input unit located on the main body of the telephone, as is well known. As described above, when a key on the key input unit is selected and pressed, the telephone terminal apparatus sends a corresponding dialing signal (DTMF signal of most current telephone apparatuses) to the public telephone network (PSTN). The dialing signal transmission as described above is widely used in response to the input of the dial digit key, and in the method of storing the other party's telephone number in a storage device such as a memory and transmitting it using a one-touch dial key. The redial method is very similar to its method.

However, most of the above-described telephone terminal apparatuses individually select a certain method, for example, a ten key (keys 0 to 9, *, #, etc.) installed on the key input unit and transmit a dial signal corresponding thereto. And a method of transmitting a dial signal corresponding to the telephone number of the other party using a buffer such as a memory and a control unit such as a central processing unit capable of controlling the buffer has the following problems.

After the transmission of one dial signal is completed, when the user dials a similar phone number, the user has to re-enter all the phone numbers again from the beginning. That is, the telephone numbers of telephone apparatuses installed in a place occupying (using or using many telephone lines (for example, a corporation, etc.) often have consecutive numbers, in which case the called party number is busy or is called. In general, most callers dial a neighboring subscriber number of the called party to find a counterpart.

However, most conventional telephone terminal devices have only a hotkey capable of dialing the same telephone number only or a redialing function of repeatedly re-sending the same number as a previously dialed telephone number. If you wanted to dial another phone number, you had to resume dialing from the beginning.

For example, the problem will be described in detail below. If a caller wants to talk to a caller located in a place having a plurality of phone numbers consecutively, the caller dials the caller's phone number, but if the caller is already busy, the caller hangs up and waits. Dialing was done by using the redial function or by hooking off again and entering the called party's telephone number from the beginning. At this time, when the callee's call is lengthened, even if the call is redialed, the call is often inconvenient. In addition, when the telephone number of the called party or the telephone number of the telephone placed adjacent to the called party is re-entered from the beginning, only one of a number consisting of multiple numbers is incorrectly inputted so that a call is not unreasonable. It causes the problem that only unnecessary telephone charges are increased.

In addition, the conventional technology adopts a method of storing a phone number individually for each of a plurality of shortcut keys in order to store a plurality of phone numbers in a shortcut key, so that a plurality of shortcut keys are required to dial a plurality of phone numbers in the form of one touch. It was set as.

Accordingly, an object of the present invention is to provide a dialing signal transmission control method of a telephone terminal device which automatically dials and transmits a telephone number adjacent to a telephone number already transmitted.

Another object of the present invention is to provide a dialing signal transmission control method of a telephone terminal device which automatically transmits a telephone number having a different end number from a telephone number already transmitted in response to one key-in.

It is still another object of the present invention to control dialing signal transmission of a telephone terminal device which automatically increases or decreases the transmitted telephone number by automatically selecting or increasing the decremented number by selecting a key that continuously increases or decreases the already transmitted telephone number. In providing a method.

Another object of the present invention is to store at least one or more telephone numbers in one hot key storage area, and to automatically dial the phone numbers stored in the storage area according to the selection of the hot key and the response status of the other party (caller). A dialing signal transmission control method of a telephone terminal device is provided.

It is still another object of the present invention to provide a dialing control method for continuously storing at least one or more telephone numbers in one hot key and automatically transmitting the next telephone number when a called subscriber corresponding to the first telephone number is busy. have.

According to one aspect of the present invention, there is provided a dialing signal transmission control method for a telephone apparatus having a dialing signal corresponding to an input of a key input unit and a dialing signal corresponding to a one touch key. A one-touch phone number storing process for storing at least one phone number, and when the one-touch key is selected, accessing the first stored phone number among the phone numbers stored in the storage area and sending out as a dial signal and responding to the other party; According to the call mode or a dialing process for automatically transmitting the phone number stored in the next position of the transmitted phone number.

According to still another aspect of the present invention, there is provided a dialing signal transmission control method for a telephone apparatus having a dialing signal corresponding to an input of a key input unit and a dialing signal corresponding to a one touch key. Dialing a telephone number stored in an area to detect whether the other party has answered; and increasing or decreasing the number of the transmitted telephone number in response to an input of an increase / decrease key while the current state is busy. A second search process for transmitting as a signal and detecting a response state of the other party; and when it is determined that the search result of the second search process is a response of the other party, a communication path is formed and the other party is busy or no response. The automatic dialing process may be repeated from the second search process.

2 is a flow diagram of dialing transmission control according to an embodiment of the present invention.

3 is a flowchart of a dialing transmission control according to another embodiment of the present invention.

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

1 is a block diagram of a telephone terminal device for carrying out the present invention, which is configured as follows. A key input unit 12 for detecting a ten key for dialing and a one-touch key, and a control unit for analyzing the transmission of a dial digit corresponding to the key signal output from the key input unit 12 by the predetermined program. 14 and a Network Control Unit (NCU) (or also called a telephone network interface) for forming a call loop with the public telephone network (PSTN) under the control of the controller 14 to interface with the public telephone network (PSTN). A tone / pulse generating unit 17 for generating a tone / pulse (DTMF / pulse) corresponding to the input of the dial digit and transmitting the tone / pulse (DTMF / pulse) to the public telephone network (PSTN) through the NCU 15; A tone detector 19 which detects various tones received through the control unit 14 and transmits the tones to the control unit 14; a ROM 16 and a control unit 1 storing an operation program of the control unit 14; It consists of RAM 18 which stores / outputs 8 processing data.

2 is a flow diagram of a dialing transmission control according to an embodiment of the present invention, which is configured to dial a telephone number stored in an area corresponding to the one-touch key when one-touch key is selected to connect a call path according to a response state of the other party, The process of increasing and decreasing the dialed telephone number and redialing according to the user's selection of the increase / decrease key is shown.

First, the operation of the first embodiment constructed according to the present invention will be described in detail with reference to FIGS. 1 and 2 as follows.

Now, when the user hooks up with a handset (not shown) connected to the NCU 15, the controller 14 detects this in step 24 of FIG. The controller 14, which detects the hook-off, controls the NCU 15 to form a communication path between the public telephone network (PSTN) and the telephone, and scans the output of the key input unit 12 to detect whether there is a key input in step 26.

If it is determined that there is a key input in step 26 of FIG. 2, the controller 14 searches whether the key signal input in step 28 is a one-touch key. If it is determined that the search result input key signal is a normal key, for example, a key signal of 0 to 0, #, *, etc., the control unit 14 returns a digit corresponding to the selected key to tone / pulse generator 17. To supply. The tone / pulse generator 17 generates a tone of a dial digit corresponding to the input digit and outputs the tone to the NCU 15 so that a dialing signal corresponding to the corresponding key is output in step 30 of FIG. In step 32, the tone detector 19 reads the output of the tone detector 19 to determine whether the response signal transmitted from the public telephone network (PSTN) corresponds to the dialing.

The tone detector 19 has a function of detecting various tones output from a public telephone network (PSTN) and received through the NCU 15 and outputting them to the controller 14 when busy tone is detected. That is, the tone detection unit 19 is a digital signal by the state of the busy tone (0.5 seconds continuous, 0.5 seconds interrupted) or ringback tone (1 second continuous, 2 seconds intermittent sound) transmitted from the public telephone network (PSTN) It is shaped and supplied to the control unit 14. Detection of such a busy tone may use a technique widely used in the art as it is.

If the tone signal transmitted from the public telephone network (PSTN) of FIG. 32 is not a signal indicating a busy state, the controller 14 controls the NCU 15 to process the voice of a handset (not shown). The call path is connected to the public telephone network (PSTN). If the tone signal from the public telephone network (PSTN) is a busy tone, the hook-on state is detected in step 36. At this time, when the user puts down the handset connected to the NCU 15, the user is hooked on, and the controller 14 detects this and ends the operation of the telephone dialing.

If it is determined that the key signal input in step 28 is the one-touch key, the controller 14 accesses the digit data of the telephone number stored in the storage area of the corresponding key and supplies it to the tone / pulse generator 17 in step 38. When the dialing tone signal corresponding to the one-touch key is output from the tone / pulse generator 17 by this operation, it is transmitted to the public telephone network PSTN through the NCU 15. At this time, the controller 14 reads the output of the tone detector 19 that detects the tone signal input from the public telephone network (PSTN) through the path described above, and searches in step 40 whether the counterpart is busy.

If it is not the search result busy state of step 40, the process jumps to step 34 and switches to the call mode. If the search result is busy state, the controller 14 searches whether the input or decrease (+,-) key is input in step 42. At this time, when the user listening to the busy tone selects one of the increment key (+) or the decrease key (-) located on the key input unit 12, the controller 14 increases or decreases the number of the telephone number transmitted in step 44. do. For example, when one-touch key is selected and the phone number 123-4567 stored in the area of the one-touch key is transmitted in step 38, but the other party is busy, and the user selects one of the increase or decrease keys, In step 44, a phone number of 123-4568 or 123-4566 is generated. The controller 14 outputs the digits 123-4568 or 123-4566 produced by the operation of step 44 to the tone generator 17 in step 46. By this operation, the dialing tone / pulse signal corresponding to the dialed telephone number is transmitted to the public telephone network PSTN through the NCU 15. When the phone number 123-4567 stored in the area of the one-touch key is busy by the above operation, the phone number 123-4568 or 123 adjacent to the phone number 123-4567 is automatically selected by the increase key or the decrease key. It can be seen that the dial signal corresponding to the telephone number of -4566 is automatically sent.

The controller 14 dialing by performing process 46 of FIG. 2 detects whether the other party is busy as a tone detection signal received through the NCU 15 and the tone detector 19 in step 48. At this time, if the counterpart is busy, the controller 14 repeats the process from step 42 of FIG. 2 and automatically dials the telephone number according to the selective input of the increase / decrease key. However, in step 48, if the counterpart is not busy, the counterpart switches to the call mode in step 50, and in step 52, searches for whether the user hooks on and proceeds according to the status.

Therefore, when the other party is automatically dialed by the one-touch key under the control of the procedure shown in FIG. 2, the number of the dialed telephone number is different from the dialed telephone number only by selecting the increase or decrease key, that is, the callee who wants to call. By automatically dialing the telephone number adjacent to the telephone number of the has the advantage that it is possible to quickly dial the caller when using in companies with a continuous telephone number.

In FIG. 2, only the method of dialing by increasing or decreasing the end of an already transmitted telephone number using the increase / decrease key has been described. However, only the end number can be dialed using the numeric keys.

[Operation of Second Embodiment]

3 is a flow chart of a dialing transmission control according to another embodiment of the present invention, which accesses the first stored telephone number among the telephone numbers stored in the storage area in response to the selection of one shortcut key having at least one telephone number stored therein. It shows the process of transmitting by dial signal and automatically transmitting the telephone number stored in the call mode or the next position of the transmitted telephone number according to the response state of the other party. Such a program is masked in ROM 16 shown in FIG.

In order to control dialing in the same manner as in FIG. 3, at least one phone number must be stored in a storage area of a shortcut key. The method of storing such a phone number can be the same as the method of inputting a phone number of a conventional shortcut key, and there should only be a code for distinguishing a phone number from another phone number. That is, the code of * and # separates the telephone number with the number of consecutive digits. For example, when two phone numbers are stored in one shortcut key, the number is 1234567 * 8901234. Here, 1234567 and 8901234 are independent telephone numbers, and their telephone numbers are telephone numbers of telephones placed in the same area (exchange of the same company or telephone numbers in the same office).

The operation of the second embodiment constructed according to the present invention will be described in detail with reference to FIGS. 1 and 3 as follows.

When the telephone apparatus of FIG. 1 programmed in the same procedure as that in FIG. 3 is operated, the controller 14 detects the hook-off state in step 52 of FIG. If the search result is hooked-off in step 52, the controller 14 searches whether a shortcut key is input in step 54. If the key input in step 54 is not a shortcut key, the controller 14 performs an operation below step 58 to output a dial signal corresponding to the input key. Processes 58 to 64 shown in FIG. 3 are the same as processes 30 to 36 of FIG.

If it is determined in step 54 that the signal of the input key is a shortcut key, the controller 14 searches whether there is more than one telephone number assigned to the selected shortcut key in step 56. If two or more telephone numbers are not stored in the storage area of the selected shortcut key, the controller 14 performs the above step 30 to dial the telephone number corresponding to the shortcut key. However, if it is determined that two or more telephone numbers are stored in the selected shortcut key as a result of the search in step 56, the controller 14 accesses the first telephone number among the telephone numbers stored in the area of the shortcut key in step 66. In step 68, the controller 14 controls the tone / pulse generator 17 and the NCU 15 to dial out the first stored telephone call stored in the shortcut key area, and to check whether the other party is busy in 70. If it is determined in step 70 that the other party is not busy, the controller 14 switches to call mode in step 72.

However, if it is determined that the other party is busy, the controller 14 searches whether the telephone number transmitted in step 74 is the last number of the telephone number assigned to the shortcut key. If it is determined that the last number is not the last number in step 74, the controller 14 reads the next phone number in step 76, dials, and then searches in step 78 for the status of the other party. In this case, it should be noted that the operation of dialing in step 76 is performed by restoring the telephone line and forming a call loop again. That is, the controller 14 controls the NCU 15 to hook-on the telephone line and then hook-off again to transmit the next telephone number. In this case, when it is determined that the other party is busy, the controller 14 searches for the user's hook-on state in step 80 and recovers the line at the hook-on state to stop the dialing operation.

As described above, at least two or more telephone numbers are allocated and stored in one shortcut key, so that when the first telephone number is busy, the second telephone number is automatically dialed so that the call can be established more quickly.

As described above, the present invention provides an error caused by a wrong operation of the user's selection behavior by automatically transmitting the transmission of adjacent telephone numbers consecutively to the dialed telephone number when dialing using the one-touch key by the selection of the minimum ring key. It can be minimized. In addition, by assigning and storing at least one phone number in a storage area of one shortcut key, dialing can be more easily performed by automatically dialing the phone numbers stored in the area of the shortcut key according to a call state of the other party.
