Description

Transfer Auto Dial Method

The present invention relates to a dialing method of a dialing device, and more particularly, to a method of automatically repeating dialing sequentially until a phone call is made by one dialing.

1 is a block diagram of a telephone to which the present invention is applied, and the controller 10 controls the overall operation of the telephone. The memory 14 stores a program and temporarily stores data generated during program execution. In addition, a call buffer for storing a telephone number input during an outgoing call and a call switching auto dial buffer for performing a call transfer auto dialing function are provided. The memory 14 may use EEPROM. The key input unit 12 is provided in a matrix structure using keys for setting various functions and modes using the principles of switches and latches, and numeric keys for performing dialing functions. In addition, key data corresponding to the key pressed by the user is output to the controller 10. The ring detection unit 24 is connected to the telephone line and detects a ring signal input to the telephone line in the on-hook state and notifies the control unit 10 that the incoming call request state. The hook relay 22 performs a function of connecting and disconnecting a telephone line and a call path of the telephone by a control signal of the controller 10. The call circuit unit 20 is connected to the hook relay 22. The call circuit unit 20 is a speech IC, and processes various tone signals and voice signals connected to and connected to a telephone line. The DTMF generation unit 16 is connected between the control unit 10 and the call circuit unit 20, and converts the key data output from the control unit 10 into a DTMF signal and outputs the DTMF signal to the call circuit unit 20. The pulse generator 18 is a type of multi-frequency code (MFC) signal system. Each signal is transmitted with a predetermined length and is used to increase the reliability of the signal. One of the DTMF generator 16 and the pulse generator 18 may be selected and used.

Typically, companies or organizations use multiple phone numbers. 2 is a control flow diagram illustrating a conventional dialing method, which shows a dialing method when calling a company or a group as described above. 460-2861, 460-2862, 460-2863 Here is an example of how to dial a company or organization with three telephone numbers.

When the user wants to place a call with three phone numbers as described above, the control unit 20 determines whether a hookoff signal has occurred in step 201 and checks whether a phone number 460-2861 signal is input in step 202. When telephone number 460-2861 is input by the user, the telephone number 460-2861 is transmitted. Then, the controller 10 checks in step 203 whether the ringtone is input, and in step 204, if the hook-up sound is input. In addition, if the hook-on is detected, the control unit 10 again checks whether a hookoff has occurred in step 205, and if the hook-off is detected, examines whether a telephone number 460-2862 is input. If the telephone number 460-2862 is input, in step 207, the controller 10 checks whether a ring tone is detected. The controller 10 checks whether the hook tone is detected in step 208. The controller 10 checks in 209 whether it is hooked off to prepare for the next telephone number signal. It then checks if the third telephone number 460-2863 is entered in 210, and if so, in step 211 it checks whether a call tone has been detected. As described above, when all the telephone numbers 460-2861, 460-2862, and 460-2863 detect a busy tone, the control unit 10 will feed back to step 201 to resend the first telephone number 460-2861.

As described above, the user must hook off and hook on one by one, and repeatedly press the dial key several times. In other words, since the same phone number must be dialed many times repeatedly until a call is made, it is inconvenient and consumes a lot of time until the call is made.

Accordingly, an object of the present invention is to provide a method for automatically dialing a plurality of telephone numbers repeatedly with one dialing.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

3 is a control flowchart illustrating a method for automatically dialing a plurality of phone numbers according to an embodiment of the present invention, and FIG. 4 is a memory map for storing a plurality of phone numbers according to an embodiment of the present invention. Suppose you dial to a location with three phone numbers 460-2861, 460-2862, and 460-2863 with reference to FIGs.

First, the controller 10 checks whether it is always hooked off in step 301. When a hookoff signal is detected from step 301, the controller 10 checks whether a function key is input in step 302. When a function key is input from the key input unit 12, the control unit 10 receives a function key signal and executes call switching dialing mode setting in step 303 by a program. When the setting is made, the controller 10 checks whether a plurality of telephone numbers 460-286 # 1 # 2 # 3 * have been input without sending the input key data to the telephone station. Here, the # key is a delimiter for distinguishing a plurality of telephone numbers, and the * key is a terminator for recognizing the control unit 10 that a plurality of telephone numbers are finished. When the phone number is input, in step 304, the controller 10 stores the phone number 460-286 # 1 # 2 # 3 * in the memory 14 as shown in the memory map of FIG. 4. Figure 4 is a memory map for storing a plurality of telephone numbers according to the present invention, a common phone number (Common Phone Number) (460-286) is stored in address A and telephones are distinguished by the delimiter in B, C, D address The number is stored. After the storage, the control unit 10 reads the common telephone number 460-286 stored in the address A of the memory 14 and the address B of the separator number 1 and dials the telephone number 460-2861 in step 306. After the execution of step 306, the controller 10 checks in step 307 whether a ringtone sound is input. When the call tone is detected, the controller 10 reads the number 2 of the C address and dials the telephone number 460-2862 in step 308. After step 308, in step 309, it is checked whether a chord sound is input. If the call tone is input, the controller 10 reads 3 of the D address and dials the telephone number 460-2863 in step 310. After dialing in step 310, the controller 10 checks whether a call tone is detected in step 311. If the ring tone is detected, the control unit 10 returns to step 306 and repeats until the call. If a ring back tone signal is not detected in step 307, 309, and 311, and the ring back tone signal is detected, the controller 10 checks whether a receiver hookoff signal is input in steps 312, 313, and 314. If the receiving hookoff is not detected, the next number is dialed. If the hookoff signal is detected, a call path is formed in step 315.

As described above, the present invention has the advantage that the user does not need to repeatedly press a plurality of telephone numbers by automatically dialing a plurality of telephone numbers with one dialing.

Secondly, by dialing multiple times with one dialing, the user can save time by doing other things until the call is made.
