2 is an exemplary view showing an appearance of a telephone to which the present invention is applied, and FIG. 3 is an exemplary view showing an appearance of a dedicated keyboard for inputting text into the telephone as shown in FIG.

In the drawings, 1 is a telephone body to which the present invention is applied, 2 is a liquid crystal display, 3 is a handset, 4 is a numeric keypad, 5 is an UP KEY and a DOWN KEY, and 6 an end key ( END KEY), 7 is the SEND KEY, 8 is the Display On / Off, 9a is the Memory Function Key, and 9b is the Keyboard Connector.

As shown as a temporary example in the figure, the telephone to which the present invention is applied has a large memory (not shown) and a display 2 of a predetermined size in a main body, and the Korean consonants have 12 keys (4 And a numeric keypad 4 appropriately assigned together with the corresponding numbers, an UP KEY and a DOWN KEY 5 provided on one side of the numeric keypad 4, and the numbers. An end key (END) 6, a send key (SEND) 7, a display on / off key 8 and a memory function key 9a provided below the keypad 4 are provided, respectively. In addition, it is provided with a keyboard connection connector (9b), it is possible to record the respective call data in the memory with a detachable keyboard, an example of the dedicated keyboard used at this time is shown in FIG.

On the other hand, instead of the separate dedicated keyboard described above, a generalized and widely spread keyboard of a computer may be used, and a keypad or numeric key (0 to 9) of a telephone or a facsimile itself is already widely used without using a separate keyboard. You can also use the combination of the * key and the # key.

Now, a method of applying the present invention to the Hangul character system will be described. That is, the present invention stores a plurality of calling phone numbers with data such as names, addresses, and the like; three consonant consonants among the Hangul names of the person to be called are written together with the numbers on the numeric keypad 4. When pressing continuously while viewing, the corresponding call data is output to the display 2 so that the user can check it, and if it is corrected, auto dialing is performed, so that the call can be stored quickly and easily while storing a large number of call data. It is easy to find data and implement speed dialing.

To explain this in more detail, as is well known, a single Hangul character is composed of a consonant, a neutral, and a consonant. A consonant is used as a consonant, a vowel, and a consonant as a consonant. Therefore, the present invention uses this principle, taking only the Korean consonant consonants and correspond to the 12 keys of the telephone numeric keypad 4 as shown in Table 1 below, the existing numeric keypad 4 is added without additional keys You can use it as it is.

In addition, as described later in the description of FIG. 5, mode designation keys (Keep, Delete, Hangul, Phone) and a separate consonant assignment key are added to the present invention. It is also possible to implement an automatic dialing method of.

In addition, the Korean name usually consists of three syllables. In the present invention, by pressing only three keys assigned to the beginning of each syllable among the three syllables, the corresponding data can be displayed to easily and quickly access the desired data. It is to be.

For example, when you want to call a person named Kim Chul-soo, if you press the key button of a (1) key (*) key (7) on the numeric keypad 4, the phone 1 The display 2 outputs the name and address of Kim Chul-soo and a telephone number thereof. After the user checks the data, the user presses the SEND button 7 to dial the number.

In addition, considering that the processing speed of the CPU is considerably fast, the conventional sequential addressing method may be used as a data storage and retrieval method for automatic dialing, and each data is stored in the memory as follows. It is also possible to use a random acces method that inputs randomly and withdraws randomly.

As an example, the relationship between the assigned address and the key value in the case of addressing so that 10 addresses are assigned to each combination of three Hangul first consonants of each call data is shown in Table 2 below.

The reason for assigning 10 memories to each key value in Table 2 is that all three initial consonants are allocated in consideration of the occurrence of duplicate data. It is also easy to purchase inexpensive large-capacity memory due to the development of, and can be further expanded according to the capacity of the adopted memory.

For example, if all three key values overlap

「Kim Cheol Soo → ㄱ, ㅊ, ㅅ

River asthma → ,, ㅅ, ㅅ 」

In this case, it is often the case that all three primitives representing the representative value are the same.

However, in one preferred embodiment of the present invention, when the displayed data is not the desired data, the same kind of data is retrieved while passing one by one up and down keys 5 provided in the telephone.

In addition, the present invention can be applied to English characters as well as to Korean characters as described above, as well as to a variety of character systems, as an example. .

In this case, as in the case of the above-mentioned Hangul system, a full name usually consists of three words. A total of three letter combinations, one initial letter of each called party, are addressed in one memory area. As shown in Table 2, even if duplicate data is generated by allocating a plurality of memories to each key value, the desired data can be retrieved using the UP and DOWN keys of the telephone.

4A and 4B are flowcharts illustrating a process of performing the automatic dialing method according to the first embodiment of the present invention.

As shown in the figure, in the present embodiment, first, a hook detection signal is input to determine whether to hook off (401). Thus, when the hook off, the normal call mode is performed (402), and then the process returns to the process of determining whether the hook is off (401), and the memory function key (403) when the determination result is not the hook off. And scan the state of the display on / off key 404 at short time intervals, and when the memory function key is input (403), prompt information is immediately output to the display (2 in FIG. 1). Allow the function to select and wait (421). In this embodiment, press numeric key 1 to register new, press numeric key 2 to modify data already recorded, and press numeric key 3 to complete the desired operation or to exit this memory mode (ESC). Was pressed.

Thus, if the user presses the numeric key 1 (422), the user proceeds to a new registration mode to sequentially store (423, 425, 427) a new name or trade name, a phone number and a simple memo input by the user. The memory area to be stored is determined by the new name or a combination of three-digit initial consonants. When the user presses the numeric key 2 (422), the user proceeds to a mode of correcting already registered data and performs a search process for searching for data to be corrected first, and whether the input key is an appropriate call code key. Check (429), if it is not a proper code key (e.g. 0 to 9, *, #), i.e., SEND, UP or DOWN key, a buzzer will be generated for user recognition (430). Is inputted to display first consonants (a, b, c…) or voting (END) (.) Corresponding to the input call code, and the process (429) until three appropriate code keys are input. To 432) are repeated. Thus, when three appropriate code keys are input, the corresponding data is retrieved (433) and the corresponding stored data is displayed (434).

Then, it is determined whether the up-down key 5 is input for a predetermined time (435), and if it is input, the search and display processes 433 to 435 are repeatedly performed. If there is no up-down key input for the predetermined time, the correction is made. It is determined whether a key is input (436). Thus, when a modification key is entered, the currently displayed registration data is modified and stored (437). If the updown key 5 or the correction key is not input for a predetermined time (436), the process returns to the process 421 of outputting guide information to the display (2 in FIG. 1).

In addition, after the process 421 of outputting guide information to the display (2 in FIG. 1), when the numeric key 3 is input, the process returns to the first hookoff state determination process.

On the other hand, in the hook-off state, when the display key is turned on (404), it is checked whether the input key is an appropriate calling code key (405), and an appropriate code key (for example, 0 to 9, *, #). ), I.e., SEND, UP or DOWN key, generates a buzzer sound so that the user can recognize it (406). ...) or END (.), Respectively, and the above processes 405 to 408 are repeated until three appropriate code keys are inputted. When three appropriate code keys are input, the corresponding data is retrieved (409) and the corresponding stored data is displayed (410).

Then, it is determined whether the up-down key 5 is input for a predetermined time (411), and if it is input, repeats the search and display process (409 to 411), and if there is no up-down key input for the predetermined time, It is determined whether the key SEND is input (412). Thus, when the calling key is input, the general call function is performed by dialing the telephone number of the currently registered registration data (413), and then the process returns to the first hookoff determination process (401). However, after retrieving (409) and displaying the data (410), if the up-down key (5) or the originating key is not input (411, 412) for a predetermined time, the process immediately returns to the first hook-off determination process (401). Goes.

The present invention allows data for automatic dialing to be sequentially input or output into a memory, so that the name of the called party (name or company name) can be obtained even if the user does not individually remember the call data (name, telephone number, etc.) to be speed dialed. If only the speaker is remembered, it is convenient to automatically dial by pressing only three code keys corresponding to the initial consonant of the name speaker and then pressing the originating key (7).

5 is an exemplary view showing the appearance of a telephone to which the second and third embodiments of the present invention are applied. The main body is provided with a predetermined memory (not shown) and a display having a predetermined size. As you can see, Hangul consonants a, b, c… ㅌ is assigned sequentially to 12 keys (numeric keys 0-9, *, #), the rest to the FLASH key, to the additional keys provided separately, and to the. PAUSE) key.

And, at the bottom of the display located above the numeric keypad, mode designation keys (Keep, Delete, Hangul, Phone) are arranged, and the UP KEY and the UP key on the right side of the numeric keypad. DOWN KEY, Hold and SEND keys are provided respectively.

6A to 6D are flowcharts illustrating the automatic dialing method according to the second embodiment of the present invention.

As shown in the figure, it is determined whether the hook off by inputting the hook detection signal (601). Thus, when the hook-off proceeds to 1 to perform the normal call mode, if not the hook off checks whether there is a Hangul mode key input (602). Thus, if the Hangul mode key is input (602), the phone mode key 603, the registration mode key 604, the delete mode key 605 is input or the initial character key 607 is input within a predetermined time. When the mode change key is input, the process proceeds to the corresponding execution mode, and if the initial character key is input, it checks whether or not the three-digit input is completed (608). Thus, if the three-digit input is completed, it is searched whether or not data exists in the corresponding address area (609). If there is no data in the corresponding area (610), it outputs no data on the display, and if there is data in the corresponding area, the stored data are sequentially displayed according to the up-down key input (612, 613). Make a choice. Thus, when the user selects specific data with the originating key (SND) (614), it is automatically hooked off and occupies the call line (615) and then generates a dialing tone of self-selected data (616). In this case, if there is no call key input (614), the process proceeds to step (613, 614, 615).

On the other hand, as a result of determining whether the mode switch key is input, when the phone mode key is input (613), once the switch is switched to the off state to occupy the call line, a separate key input for switching to the Hangul mode as described above. Unless there is a 617, when the called party's telephone number is completed, dialing is performed (619). Then, it continuously checks whether there is a function key input (620) and performs a function corresponding to the input key (621). If there is no function key input or the function is completed, the hook-on is checked again for the first time. It returns to the standby state of 622 (see also FIG. 6b).

When the registration mode key is input as a result of determining whether the mode switching key has been input (614), three initial voice keys are displayed while checking whether or not there is a key input for switching to another mode (623-625). Then (627), likewise confirms whether there is a key input for switching to another mode (628-630) while receiving a phone number (631) and displays the bar, when the input is completed and the user presses the calling key ( 632, the current input data is registered at the corresponding address to be allocated (633). If there is a key input within a predetermined time, the process (623-633) is repeated, and if no key is input for a predetermined time, the process returns to the initial standby state (see also 6c).

On the other hand, as a result of determining whether the mode switch key is input, if a delete mode key is input (615), while checking whether or not there is a key input for switching to another mode (634-636) and receives three initial consonant keys display If the user presses a send key for checking whether the contents to be deleted are correct (639), the current displayed input data is deleted (640). If there is a key input within a predetermined time, the process (634-640) is repeated, and if there is no key input for a predetermined time, the process returns to the initial standby state (see also 6d).

Thus, the user simply registers and deletes the call data (name, phone number, etc.) to be speed dialed, simply registers and deletes it, if necessary, presses only three code keys corresponding to the caller's initial consonant and only the calling key (7). Press to conveniently auto dial.

7 is a flowchart of registration mode execution of the automatic dialing method of the third embodiment according to the present invention.

In the third embodiment of the present invention, when the registration mode is selected during the execution of the above-described second embodiment, the cursor shift key is entered after each initial vowel key and numeric key are input during the procedure as described in FIG. 6C. By checking the input (705-708, 714-717), you can move the cursor to the desired position. Thus, it is possible to further improve the convenience of use by allowing the cursor to be modified by moving only the portion that is incorrectly input when performing the registration mode as in the second embodiment.

In addition, the present invention as described above, in addition to the general telephone, mobile phone (hand phone), car phone (car phone) and ISDN telephone in addition to any communication terminal connected to the public communication network, such as a facsimile, etc. Applicable

Therefore, compared to the conventional case, the present invention is convenient to use by automatically dialing only three key combinations corresponding to the initial consonant of the called party name (or business name) that is directly used in real life instead of a telephone number and easily remembered. In addition to greatly improving the performance, it is a very excellent invention that is widely applied to all communication devices having a display and a predetermined memory.

Of course, the foregoing description is presented as a preferred embodiment of the present invention, the present invention is not limited thereto, and various modifications may be made within the spirit and scope of the present invention, and the terms and expressions used herein are for the purpose of limitation. It will be apparent to those skilled in the art from the foregoing description that the term is not intended to be used as an explanatory term, but rather to exclude the equivalent.
