Description

How to Speed Dial on Your Phone

The present invention relates to a speed dialing method in a telephone, and in particular, a plurality of telephone numbers can be stored in each speed dial number in a telephone, and by automatically dialing previously stored telephone numbers when a speed dial number is input by a corresponding telephone user. The present invention relates to a speed dial method in a telephone for making a call with a counterpart party.

In general, a function of storing and dialing a telephone number in a telephone has been a one-touch button (short dial) function. This one-touch button function stores one telephone number corresponding to a specific number (shortcut number) by the user's key button operation, and then, when the user wants to dial the stored telephone number, the handset is off-hook ( Off Hook) or turn on the speaker phone, and then enter a specific number that you specify to automatically dial a pre-stored phone number.

In a conventional phone, only one phone number can be stored in one speed dial number. Therefore, when a corresponding speed dial number is automatically dialed by entering the speed dial number, if the other party is busy or does not answer, the caller needs to hang up and call again. did.

On the other hand, in a place where a private exchange system is used, such as a public institution or a company, when an extension subscriber wants to enter a department having a plurality of telephone numbers in a shortcut number, only one telephone number can be entered in one shortcut number. Therefore, it was necessary to assign a number of speed dial numbers for a department, and if a number of telephone numbers used by each department uses only the last digits, a service that enables automatic redialing by pressing only the last digit is available. However, this service was not provided when the telephone numbers used by one department had different numbers.

As described above, the speed dial function of the conventional phone has a limitation that only one phone number can be stored in one speed number, and when a speed dial number is input by a user, the corresponding phone number is automatically dialed. If the other party is busy or does not answer, the user has to hang up and try again.

The present invention has been made to solve the problems described above, the object is that if the phone user enters a plurality of phone numbers in each speed dial number stored in the phone, if the speed dial number is input by the user, the call is By automatically dialing the pre-stored phone number until it is made, it provides the improved speed dial function to the phone user.

Features of the present invention for achieving the above object, the first process of storing a plurality of telephone numbers input in response to a shortcut number from the user; And a second process of automatically dialing the telephone number sequentially when the speed dial number is input by the user.

The first process includes a first step of receiving a specific button from a user; Allocating a memory area corresponding to the specific button; Storing a telephone number authorized from the user in the memory area; After the third step, if a predetermined button is input from the user, characterized in that it comprises a fourth step to perform the operation of the third step to store a plurality of phone numbers in one speed dial number.

On the other hand, the second process is a first step of withdrawing the highest phone number previously stored in the memory area corresponding to the shortcut number input from the user; A second step of automatically dialing the retrieved telephone number and determining whether a call is in progress; A third step of performing a repetitive operation by returning to the second step after withdrawing a pre-stored next telephone number when the call is in the second step; In the second step, if the other party answers the call while not in a call, if the other party does not answer after a predetermined time, the third party performs the speed dialing function until the call is made. It characterized in that it comprises a fourth step to make.

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

The telephone TEL according to the present invention has a call circuit section 11, a handset 12, a dial circuit section 13, a keypad 14, a central processing unit 15, a timer 16, as shown in FIG. And a memory unit 17.

The call circuit unit 11 connects or blocks the communication path between the public communication network and the handset 12 under the control of the central processing unit 15, or the call side with the handset 12 according to the cutoff signal from the dial circuit unit 13. Blocking the handset 12 serves to input and output the voice call signal.

When the key button is input by the user's keypad 14 operation, the dial circuit unit 13 sends a cutoff signal to the call circuit unit 11 to cut off the talk side with the handset 12, and connect with the call circuit unit 11. The dial signal is transmitted to the public communication network through the telephone line, and the dial signal corresponding to the telephone number can be heard through the receiver side with the handset 12 and under the control of the central processing unit 15. Send the.

The keypad 14 includes a numeric button for dialing a telephone number of the other party or a function button for performing a specific function. The central processing unit 15 controls the operation of the entire telephone TEL. It controls the operation of recording and extracting the telephone number for 17) and the operation for automatically dialing the extracted telephone number sequentially.

The timer 16 counts the time according to the control of the central processing unit 15, and the memory unit 17 allocates a memory area for each address number, and sequentially orders a plurality of telephone numbers input corresponding to each address number. Save as.

The operation of storing the telephone number input by the user for the speed dial function in the telephone TEL according to the present invention configured as described above is performed in the order shown in FIG. 2.

First, after the handset 12 is off-hook by the user, a specific button for inputting speed dial information (phone number) (button for storing a phone number in a specific speed dial number) is inputted (step S11). The device 15 is prepared to accept a telephone number (allocating a memory area corresponding to the abbreviated number) (step S12). At this time, when the user operates the keypad 14 to input the telephone number (step S13), the central processing unit 15 sequentially transfers the input telephone number to the memory area of the memory unit 17 assigned to the shortcut number. After storing (step S14), it is determined whether a predetermined button for inputting the next phone number is input to the corresponding memory area (step S15). If the predetermined button is input, the operation of step S13 is repeated to perform multiple phone numbers. If it is possible to save, and if a predetermined button is not input, it is determined whether a specific button for inputting speed dial information is further input (step S16). If a specific button is further input in step S16, the flow returns to step S12 to perform a repeat operation, and if no specific button is further inputted, the operation ends.

On the other hand, the speed dial operation in the telephone TEL according to the present invention is performed in the order shown in FIG.

After the handset 12 is off-hook by the user, if a shortcut number for dialing a previously stored telephone number is input (step S21), the central processing unit 15 stores the memory of the memory unit 17 corresponding to the shortcut number. After retrieving the highest telephone number previously stored in the area (step S22), the dial circuit unit 13 is controlled to automatically dial the retrieved telephone number (step S23). After step S23, the central processing unit 15 determines whether a call tone is received by the call circuit unit 11 via the telephone line, i.e., whether the other party is busy (step S24), and if the other party is busy, the corresponding memory. It is determined whether there are any telephone numbers already stored in the area (step S25). If there are no phone numbers already stored in step S25, the operation ends. If there are more phone numbers already stored, the next phone number is withdrawn from the corresponding memory area of the memory unit 17 (step S26), and the flow returns to step S23. The repetitive operation will be performed. On the other hand, if the other party is not busy in step S24, the central processing unit 15 controls the timer 16 to start the time counting of the timer 16 (step S27). It judges (step S28). In step S28, when the counterpart caller answers, the central processing unit 15 controls the call circuit section 11 to construct a call path and make a call (step S29). Then, the operation is terminated. It is determined whether the time coefficient of (16) passes a predetermined time previously stored in its own memory (step S30). If the predetermined time does not pass, the flow returns to step S28 to perform a repeating operation. 16) (step S31), the operation of step S25 is repeated to perform the speed dial function until a call is made.

In the telephone TEL according to the present invention as described above, for example, six telephone numbers from 50-7943 to 50-7948 are sequentially input to the speed dial number '1' by the user. When the speed dial number '1' is inputted by the corresponding user, the central processing unit 15 first transmits the telephone number of the first stored number 50-7943 to the memory section 17. When the other party is busy or does not answer even after a predetermined time elapses, the telephone number of '50 -7944 'stored second in the memory unit 17 is automatically dialed after If the other party is busy or does not answer when a predetermined time elapses, the central processing unit 15 repeatedly performs the same operation and finally dials the telephone number of '50 -7948 'so that the user can talk.

In addition, in a public institution or a company, all phone numbers of a specific department are sequentially entered in one speed dial number, and all the stored phone numbers are stored until the telephone user of the corresponding department responds by simply inputting the speed dial number. Automatically dials the sequential call so that you can deliver the information you want to inform the department. In a small office, shop, or salesperson, you can enter one's mobile phone number, home phone number, company phone number, pager number, etc. into one speed dial number to quickly and easily call the person. It becomes possible.

As described above, in the present invention, when a telephone user inputs a plurality of telephone numbers to each speed dial number and stores them in the corresponding telephone number, when the speed dial number is input by the user, the phone numbers are sequentially stored until the call is made. By autodialing, it is possible to provide improved speed dialing for the telephone user.
