BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for controlling a redial function in a telephone communication system, and more particularly, to an apparatus and method for automatically re-dialing recently dialed telephone numbers.

When you make a call using a conventional phone or a mobile phone, if the other party is busy, the same number is dialed again after a while. In this case, it is convenient to use the dial function. In the case of dialing a facial millimeter number with a telephone connected to a facsimile or a built-in telephone circuit for transmitting a document using a facsimile, the dial function is used as described above. Hereinafter, the term 'telephone number' may be used as a telephone number having a unique meaning, or may be used in a broad sense including a prefix number.

The dialer function can be implemented by storing the most recently dialed phone number in memory. In other words, the user has stored the most recently dialed phone number automatically in the memory. If there is an input of the dialing key by the user, the user can access the memory and read the stored phone number, Ring. In this way, it was possible to automatically dial a phone number once dialed repeatedly, but the phone number was limited to one. However, from the standpoint of the user, there are cases where a plurality of telephone numbers are dialed.

It is assumed that one person contacts many members to inform a specific meeting. Some of the members may not be able to make a call because they are absent or on the line. Even in this case, only the dialing function of the dialed ring number can be used only for the dialed number immediately before the call. Therefore, the user often dials the same telephone number several times, so that the user can not avoid inefficiency and inconvenience. In addition, the current trend toward the automation and modernization of office equipment is such that such inefficiencies must be reconsidered.

It is therefore an object of the present invention to provide an apparatus and a method for sequentially dialing a plurality of recently dialed telephone numbers.

According to an aspect of the present invention, there is provided a multiple-phone number redialing apparatus comprising: a memory having first to n-th (n is a positive integer) And stores the dialed telephone number in the n-th area in response to the storage key input if the telephone call fails after dialing an arbitrary telephone number for the n-th telephone number, Dialing of the first to n-th telephone numbers stored in the memory is performed sequentially in response to the input of the telephone number.

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

In the following description, specific items such as a static RAM, a CCD, and the like are shown, which are provided for a better understanding of the present invention, and the present invention can be practiced without these specific details. And will be apparent to those of ordinary skill in the art. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a diagram showing a configuration of a facsimile to which the present invention is applied.

The control unit 111 controls the overall operation of the transmission mode, the reception mode, and the copy mode of the facsimile according to the set program. The control unit 111 may include a program memory and a data memory, or may be connected to the outside as shown at reference numeral 119. The program of the present invention is stored in the program memory, and data generated during program execution is temporarily stored in the data memory. An OPE (Operating Pannel) 112 is composed of a key input unit and a display unit. The key input means of the OPE 112 generates data of a key pressed by the user for designating each mode and performing an operation of the designated mode, and outputs the data to the control unit 111. In addition, the display unit of the OPE 112 performs a function of inputting and displaying display data for indicating the operation state of the system when the control unit 111 performs each mode. The sensor unit 113 senses the presence or absence of input of a document and the existence of a print sheet, and outputs a sensed state signal to the control unit 111. [ The scanner 114 reads image data from a document by a CCD (not shown), and transfers data to the control unit 111 by photoelectrically converting the read image data. Under the control of the control unit 111, the print unit 116 prints the image data input from the image processing unit 116 on the print sheet in the reception mode and the copy mode. The image processing unit 115 encodes and decodes the image data output from the scanner 114 and the image data output from the modem 117. The modem 117 under the control of the controller 111 analog-modulates and outputs the data output from the controller 111, digitally demodulates and outputs a signal received through the transmission line. That is, the image data output from the image processing unit 115 in the transmission mode is modulated and transmitted according to the transmission format - the standard specification of the facsimile. In the reception mode, the encoded image signal input through the transmission line is transmitted from the image processing unit 115 Demodulate in its original form for processing. The NCU (Network Control Unit) 118 forms a transmission / reception path between the telephone line (tip, ring) and the modem 117 under the control of the controller 111.

FIG. 2 is a flowchart illustrating a process of registering a telephone number so as to enable a plurality of telephone conversation dialers according to an embodiment of the present invention.

(2a) is an initial state, and the variable n indicates a serial order of a telephone number that is a multi-dialed object.

In step (2b), the controller 111 detects an off hook of the handset by the user. In step (2c), a dial tone transmitted from the exchange is received. In step (2d), when the user inputs each digit of the telephone number using the key input unit 220, the user performs a dialing operation on the digit. In step (2e), it is checked whether a busy tone is received from the dialing result exchanger.

If the busy tone is received in step (2e), it is confirmed whether the storage key is input in step (2f). Wherein the storage key is for registering any telephone number as one of the multi-dialed objects.

If the input of the storage key is detected in step (2f), the data memory-static RAM of the memory 119 may be used in step 2g. - stores the telephone number dialed in step (2d) in the n-th area set in advance. In step (2h), the variable n is incremented by 1, and in step (2i), another variable N is set to the value of n. Here, the variable n has a one-to-one correspondence with 'n' indicating the area classification of the data memory. The other variable N represents the total number of telephone numbers that are multi-dialed objects.

After the step (2i), the process returns to step (2d) and waits until the next telephone number is registered.

On the other hand, if it is determined in step (2e) that no busy tone has been received, the process proceeds to step (2j) to check whether a ring back tone has been received. If a ring back tone has been received, Check the success. In other words, if the other party is off-hook and the call is established normally, it is considered that there is no necessity of the dialer. However, if the other party is absent or the caller can not be formed for various reasons, You need to confirm your intentions. Therefore, the process proceeds to step (2f). If the ring back tone is not received in step (2j), the process is terminated.

FIG. 3 is a flow diagram illustrating a multiple number dialing procedure in accordance with an embodiment of the present invention.

In step (3a), the controller 111 detects the off-hook of the handset by the user. In step (3b), a dial tone transmitted from the exchange is received. In step (3c), it is confirmed whether or not the multi-redundancy key is input. Here, the multi-redundancy key is a key input by the user for instructing the initiation of a password for the telephone numbers stored in the first to n-th areas of the data memory. (3d), the variable n is set to 1. Here, the variable n represents a serial order of a telephone number that is a multi-dialed object, and corresponds to a one-to-one correspondence with 'n' indicating the area classification of the data memory.

After step (3d) is performed, the mobile station proceeds to step (3e) and requests a dial tone to the exchange. This can be implemented by generating a pseudo off-hook signal or the like. If the dial tone is received in step (3f), the control unit accesses the n-th area of the data memory in step (3g) and reads out the dialed number stored there.

In step (3h), it is checked whether busy tone is received from the dialing result exchanger. If the busy tone is received in step (3h), the process proceeds to step (3i) for dialing the next telephone number, and the variable n is incremented by one. In step (3n), it is determined whether the variable n is greater than another variable N. Here, the variable N represents the total number of telephone numbers that are multi-dialed objects.

If the variable n is greater than the other variable N in step (3n), the process is terminated. Otherwise, the process returns to step (3e) for dialing of the next telephone number.

Referring back to step (3h), if the busy tone is not received as a result of the check in step (3h), the process proceeds to step (3j) to check whether or not the RBT has been received. And confirms the success of the call. In other words, if the other party is off-hook and the call is normally established, the corresponding area of the data memory is erased by assuming that there is no need for a dial, but if the other party is absent or the call is not formed due to various reasons, - It must remain the target of the Rydian. Therefore, if the call fails, the process proceeds to step (3i). If the call is successful, the process proceeds to step (3l). In step (3l), contents (telephone number) are erased in the n-th area of the data memory. Then, the flow advances to step (3m) to adjust the variable n and then ends the process. This is in contrast to the case in which a user erases a telephone number erased due to the success of a call and attempts a multi-dialing operation on the remaining telephone numbers, which is implemented only by reduction of the arithmetic variable as in the present embodiment It is a well-known fact.

On the other hand, if no ringback tone is received in step (3j), the process is terminated.

As described above, the present invention is advantageous in that it is possible to dial a plurality of telephone numbers, and also it is possible to reduce the time required for the subscriber to dial.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
