The present invention relates to a multifunction telephone, and more particularly, to a method for automatically converting to a digit corresponding to a set telephone number and dialing in the case of a digit registered in a digit input at the time of dialing a telephone number.

In general, a multi-function phone refers to a phone that performs various functions as well as a call function by incorporating a main processor unit (MPU) that performs overall control, unlike a general phone.

The block configuration of the multifunction telephone is as shown in FIG.

Referring to FIG. 1, the configuration will be described. The MPU 110 controls the overall operation of the phone. The ring detection unit 112 is connected to a public telephone network (PSTN), detects a ring signal received through the public telephone network (PSTN) and informs the MPU (110). The call circuit unit 116 is connected to the public telephone network (PSTN) through the interface unit 118, and is controlled by the MPU 110 to transmit and receive various tone signals and calls between the telephone circuit and the public telephone network (PSTN). A switching operation is performed to transmit and receive an audio signal. The interface unit 118 is connected to a public telephone network (PSTN) to form a call loop by a call path control signal provided from the MPU 110. The interface unit 118 is provided with a hook switch (H / S) including a hook relay, the hook switch (H / S) under the control of the MPU 110 to the public telephone network (PSTN) the call A function of connecting to the circuit unit 116 is performed. The handset unit 120 converts a voice generated from a user into an electrical signal and outputs it to the call circuit unit 116, and a handset that converts and outputs an electrical signal input from the call circuit unit 116 into an audible sound. It consists of. The memory 122 stores data generated while performing a function under the control of the MPU 110 or outputs the stored data. The key input unit 124 has a key matrix structure composed of a plurality of keys, and provides the MPU 110 with key commands and key data generated by pressing a key. The display unit 126 displays the current state of the telephone under the control of the MPU 110.

Companies that provide domestic telecommunications services have traditionally been unified, but as they are now diversified, the same telecommunications services such as long distance calls or international calls are being provided. As a result, when a long-distance call or an international call is used between companies supporting the same communication service, different rates are set and charged. Therefore, when a user wants to make a call using a low-cost line, the user has to dial an access number according to a company's request in order to access a specific low-cost line.

For example, in Korea, long-distance call service is provided by KT and DACOM. Even if the same long-distance call service is provided by DACOM, the fee is low. Therefore, in order to use the long distance service provided by Dacom, which is inexpensive, the user must dial 82, the access code, before dialing the area code.

Therefore, the user had to memorize the access number in order to access a specific line.

In addition, when making a trunk line call using a private exchange, the inconvenience of having to make a trunk line call after accessing a trunk line by pressing a trunk line connection code (usually using 9) and when the trunk line call fails due to forgetting the trunk line system Occurred.

Accordingly, an object of the present invention is to provide a method for automatically registering a digit to be dialed when a set number of digits is input together with a registration request.

Another object of the present invention is to provide a method for dialing a registered digit corresponding to the digit automatically input when the registered digit is input.

In order to achieve the objects of the present invention, if there is a number change request, a selection code is received and a registered digit is displayed in response to the input selection code, and if the deletion of the displayed digit is requested, the registered digit is deleted and a registration request is made. If there is a, it is characterized in that it comprises a step of re-registering the input digit corresponding to the selection code, and if the digit registered for the call is input, the step of dialing the registered digit corresponding to the input digit.

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

Since the configuration for carrying out the present invention has the same configuration as in FIG. 1, detailed description thereof will be omitted. In addition, it should be noted that the reference numerals according to the configuration and configuration shown in FIG. 1 use the same operation and reference numerals wherever possible.

When a number change request is detected, a process of requesting and inputting a selection code is input; and when the selection code is input, the registration code is registered corresponding to the selection code. Displaying a digit corresponding to the registered data, receiving a digit corresponding to the data to be re-registered when the input of a registration key requesting re-registration is detected, and re-registering to delete the data. When the input of the key is detected, the registration of the displayed data is deleted.

3 is a control flow diagram for performing an operation mode according to the present invention. When a digit corresponding to a telephone number for a call is input, the process of storing the temporary buffer and determining whether or not the number of digits has been stored in the temporary buffer If it is determined that more than a set number of digits are stored, the process of dialing the digits stored in the temporary buffer, and if it is determined that more than the set number of digits are not stored, compares whether the digits stored in the temporary buffer are the same as the digits registered in the registration process. If the same digit does not exist, and detects whether the next digit is input, and if there is the same digit is made a process of dialing a digit plus the registered additional number corresponding to the digit.

4A is a map structure of a memory in which digits, which are data registered by performing the registration mode, are stored, and an F area in which a digit F [N] for comparing digits input in the operation mode corresponding to one selection code is stored; When the same digit as F [N] registered in the F area is input in the operation mode, the digit T [N] for dialing is stored. The F area has a size of 5 bytes, and the T area has a size of 10 bytes.

4b illustrates a structure of a buffer that temporarily stores an input digit for comparison with a digit registered in the operation mode.

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

First, an embodiment of performing a registration mode will be described with reference to FIG. 2. In step 210, the MPU 110 detects whether there is key data input from the key input unit 124. When the input of the key data is detected, the MPU 110 analyzes the input key data in step 212 and determines that the key data requires number switching. If not, the MPU 110 proceeds to step 214. Otherwise, the MPU 110 proceeds to step 238. Perform the corresponding function according to the key data. If the MPU 110 proceeds to step 214, the MPU 110 requests input of a selection code for selecting an area of the memory 122 in which the digit to be switched is registered, and then proceeds to step 216. The method for requesting input of the selection code may be implemented as a method for requesting as a character when the display unit 126 is provided and a method for requesting as a voice guidance message when the automatic response function is provided.

When it is detected in step 216 that key data corresponding to the selection code in response to the request is input from the key input unit 124, the selection code input in step 218 is replaced with a specific designation code. It should be noted that the selection code is denoted by N below, and step 218 is intended to be clear that it may be deleted as an attached step in order to facilitate understanding of the present invention.

In step 220, the MPU 110 searches whether there is data registered in the memory 122 in response to N as the selection code. If there is no data registered in step 220, the flow proceeds to step 224. Otherwise, if data registration is detected, the display unit 126 displays the digits F [N] and T [N] corresponding to the data registered in step 222. After the display, the process proceeds to step 224. In step 224, the MPU 110 detects whether there is key data input from the key input unit 124. When the input of the key data is detected, the MPU 110 analyzes the key data input in steps 226, 232, and 236.

When the data is analyzed as key data for requesting re-registration in step 226, the MPU 110 receives a digit corresponding to data to be re-registered in steps 228 and 230 from the key input unit 124. Re-register at 120). The re-registration of F [N] performed in step 228 requires a key corresponding to the comparison digit F [N] responding to the request after requesting input of F [N] using the method performed in step 214. If it is detected that the data is input from the key input unit 124, the data is re-registered in response to the selection code N input in step 216. Re-registration of T [N] performed in step 230 is performed through the same process as step 228 described above.

If the key data is requested to be deleted in step 232, the MPU 110 deletes the data registered in the memory 122 corresponding to the selection code N input in step 216.

If it is determined in step 236 that the key data requesting the termination of the registration mode, the MPU 110 ends the execution of the registration mode.

For example, when 2 is inputted as a selection code with reference to the data registered in FIG. 4A, the process of performing the registration mode is 8203 corresponding to 3 and T [N] corresponding to F [N] registered corresponding to 2. Is displayed. If the 348 digit is input after the registration key data is input in the displayed state, the input 348 is replaced with 3 and registered. After the 348 is registered, if the digit 820348 is input, the 820348 is registered by replacing the input 820348 with 8203. Otherwise, if 3 and 8203 are displayed and the delete key data is input, the displayed 3 and 8203 are deleted from the memory.

Next, referring to FIG. 3, the MPU 110 detects whether key data corresponding to the digit of the telephone number for the call is input from the key input unit 124 in step 310. do. In step 328, the hook switch provided in the interface unit 118 is detected to be hooked on. In step 330, the key input unit 124 detects whether all the digits corresponding to the telephone number are input. Proceed with normal call mode.

When the input of the digit is sensed in step 310, the process proceeds to step 312 and stores the input digit in a temporary buffer TMP provided in the MPU 110. In step 314, the MPU 110 compares whether the number stored in the temporary buffer TMP is greater than the number registered in the F [N] region.

For example, when two digits are registered in the F [N] area in which the comparison digits shown in FIG. 4A are stored, it is compared whether two or more digits are stored in the temporary buffer TMP.

If it is determined in step 314 that the set number is stored, the MPU 110 proceeds to step 326 to dial the digit stored in the temporary buffer TMP. The MPU 110 returns to step 310 after dialing to sense the input of the next digit. However, if it is determined that the number of digits set in step 314 is not stored, the MPU 110 proceeds to step 316. In step 316, a count value N for sequentially comparing the digits stored in the temporary buffer TMP with the digits F [N] stored in the memory 122 having a plurality of selection codes is set. For example, in the following description, the count value N, which means a selection code, is set to 10 to explain.

The MPU 110 compares whether the same digits as those stored in the TMP are registered in the memory 122 until the value of N becomes 0 in steps 318, 320, and 324.

In step 318, the comparison of the count value N is greater than zero to determine whether the comparison of the digits stored in the memory 122 is completed. On the other hand, if it is determined in step 318 that the comparison is completed, the flow returns to step 310 to detect the input of the next digit. However, if it is determined in step 318 that the comparison is not completed, the MPU 110 compares whether the data stored in the F [N] area selected by the value of N is the same as the digits stored in the TMP in step 320. If it is determined in step 320 that the digit stored in the TMP is the same as the digit registered in the F [N] area of the memory 122, the flow proceeds to step 322. The MPU 110 reads and dials a digit registered in the T [N] area of the memory 122 in step 322 and returns to step 310. If it is determined in step 320 that the same digit is not the same, the count value N is decreased by one and the flow returns to step 318 in step 324.

For example, the operation of the operation mode will be described with reference to the data registered in FIG. 4A. When the user presses the digit 5, the MPU 110 stores the digit 5 in the TPM. The stored digit 5 is compared with the digit registered in the F [N] region of FIG. 4a. When the count value is 4, the MPU 110 detects that the same digit is registered and T [N]. The 8205 digit registered in the area is automatically dialed.

In another embodiment, if the access number of the private exchange in the office using the private exchange is 0546-460-2XXX, only the number marked XXX is different for each department, but only the area code (0546) and the trunk line (460) ) And the DID assignment number 2 are the same. Accordingly, the same number 0546-460-2 is registered as 77 in the memory 122, so that when the user inputs 77XXX, the registered 0546-460-2 and the input XXX are automatically dialed.

As described above, the present invention automatically dials a specific access number even when a user presses a normal telephone number as the telephone number is automatically changed by a user's selection, and an office using a private exchange does not have a private exchange. It has the same effect as you can use.
