Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, 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. Also, in the following description, many specific details such as components of specific circuits are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those of ordinary knowledge in Esau. 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.

In the following description, the number of digits refers to each number constituting a telephone number. For example, if the phone number is '745-1083', 7, 4, 5, 1, 0, 8, 3 are all single digits, and their order is meaningless. In addition, the 'specific number of digits' may mean two or three digits such as '510', '45', etc., for example, or the last four digits of the telephone number such as '1083'.

1 is a view showing the configuration of a dialing device by searching for a specific number of digits of a portable wireless telephone according to an embodiment of the present invention.

The transceiver 50 processes wireless transmission or reception signals. The key input unit 51 is a kind of user interface means, and includes a plurality of keys for inputting the number of digits to be searched, a selection key for selecting a searched phone number to generate a dialing command, and a plurality of searched phone numbers in order. Has a toggle key to indicate In response to the input of the number of digits to search for, the CPU 52 compares each phone number of the memory with the specific number of digits to search to find a phone number having a matching digit. The display unit 53 displays the telephone number found by the CPU 52. At this time, the numeric key input by the user may be displayed in a normal state, and the remaining parts may be distinguished by blinking or shading. The telephone number memory table 54 includes at least one telephone number information previously input by a user, and uses EEPROM. Call list 55b is a memory area that stores previously dialed phone numbers. The search information list 55c is a memory area for storing the phone number found by searching the phone number memory table 54 and the call list 55b. The call list 55b and the search information list 55c may be implemented in RAM. The ROM 56 stores a control program executed by the CPU 52.

2A is a diagram illustrating a structure of a phone number memory table according to an embodiment of the present invention. In this embodiment, up to 100 phone numbers can be stored, but only 5 are stored. As shown, it has its own bits indicating whether or not the phone number is stored at that address. Address 1 contains the telephone number (0331) 280-9974, so the presence / absence bit is '1' and the presence / absence bit of address 3 is '0'.

2B is a diagram illustrating the structure of a call list according to an embodiment of the present invention.

The call list only stores phone numbers that the user has actually called before. In this embodiment, up to 30 phone numbers can be stored, but only 6 are stored. Like the telephone number memory table, it has a presence / absence bit indicating whether a telephone number is stored in a corresponding address.

2C is a diagram illustrating the structure of a search information list according to an embodiment of the present invention. The search information list stores a phone number found by searching the aforementioned phone number memory table and a call list. In the state shown, the phone number memory table and the call list are searched for and stored in the phone numbers including '7204'.

3 is a flowchart illustrating a dialing method by searching for a specific number of digits according to an embodiment of the present invention. In the present embodiment, a description will be given on the assumption that three digits are set as a unit of comparison, but one or two digits are possible.

In step 309, the controller 52 initializes a parameter MATCH_CNT indicating the number of found phone numbers to '0', and then checks whether a numeric key is input in step 310. If the check result detects the input of the numeric key, in step 311, the controller 52 checks whether three digits are input, and if not, returns to step 310. When the number key is input as many as three digits, the controller 52 searches for whether there are three digits that match the three digits among the phone numbers stored in the call list 55b of FIG. 1 in step 312. When the telephone number matching the three digits is found, the variable MATCH_CNT is incremented by one each time.

Suppose you compare the phone number 3434-1102 stored in the call list 55b with the three-digit number '563' entered by the user: 343 and '563', 434 and '563', 341 and '563', 411 and '563 ', 110 and' 563 ', 102 and' 563 'in order to compare respectively.

When the search for the call list 55b is completed, in step 313, the controller 52 searches whether any of the telephone numbers stored in the telephone number memory table 54 of FIG. 1 has the three digits corresponding to the three digits. When the telephone number matching the three digits is found, the variable MATCH_CNT is incremented by '1' each time.

After completing the search, in step 314, the controller 52 checks whether the variable MATCH_CNT is greater than '0'. If the result of the check is greater than '0', it is checked in step 315 whether the variable MATCH_CNT is '1'. If the check result is '1', the found phone number is one. In step 316, the controller 52 displays the phone number stored in the search information list 55c on the display unit 53. In operation 317, the key input unit 51 is scanned to check whether the user selects the displayed telephone number. In the case of a general telephone, a predetermined key may be used, and in a portable wireless telephone, a call key SEND may be used. In this case, in step 318, the controller 52 controls the telephone number displayed on the display unit 53 to be dialed. If the user's selection is not detected in step 317 and if the variable MATCH_CNT is not greater than '0' in step 314, the process returns to step 310.

In step 315, if the variable MATCH_CNT is not '1', there are multiple phone numbers found. In this case, the controller 52 proceeds to step 319 and arranges the found phone numbers according to a specific condition. In this case, the specific condition is set in advance according to the usage, such as the frequency of dialing the telephone number or the order of the most recent dialing. Therefore, when dialing and storing an arbitrary telephone number, all the information should be stored together in preparation for the above sorting. For example, the date and time of the dialing, the cumulative value of the number of dialing of the telephone number based on a specific time point, and the like. This embodiment includes the sorting step as described above, but this is optional.

After the alignment, the variable i is set to '1' in step 320, and then the display unit 53 displays the variable MATCH_CNT and the phone number stored in the variable i th address among the sorted phone numbers in step 321. The variable i represents the address of the search information list in which the found phone number is stored. In the present embodiment, as shown in step 323, the address is sequentially increased by '1'. Thereafter, when the user inputs a predetermined key (aka toggle key) to view the next found phone number, the controller 52 detects this in step 322 and proceeds to step 322 to increase the variable i by 1 and then the step 321. Go back to step If the input of the toggle key is not detected in step 322, the method proceeds to step 317 and checks whether the user selects the currently displayed phone number.

In step 410, the controller 52 sets the variable P to '1'. The variable P represents the address of a call list search or phone number memory table. If the search is for a call list as shown in FIG. 2B, the variable P is 1 to 5, and if the search is for a phone number memory table as shown in FIG. 2A, the variable P is 1 to 100.

In step 411, the controller 52 checks whether a phone number is stored in the variable P-th address of the call list or the phone number memory table. If the phone number is stored, in step 412, all three digits included in the phone number are compared with the three digits entered by the user. In step 413, the controller 52 analyzes the comparison result and determines whether or not three digits corresponding to the telephone number are included. In this case, if a match is included, the controller 52 reads the telephone number and stores the telephone number in the search information list 55c in step 414 and increases the variable MATCH_CNT by one in step 415.

5 is a diagram illustrating a state in which the total number of phone numbers found by searching according to an embodiment of the present invention and a phone number stored at a specific address among the found phone numbers are displayed on the display unit 53.

(5a) is a state immediately after the user finishes input to search for the last four digits '7204' of the specific telephone number. As a result of the search, when three are searched as shown in FIG. 2C, for example, the message “3 found.” Is displayed, and the found telephone numbers are displayed one by one (5b) to (5d). . As shown in the input of the toggle key, the state switching of (5b) ↔ (5c), (5c) ↔ (5d) is performed. With the display shown as (5b) or (5c) or (5d), the user simply enters the selection key with one-touch and the telephone number displayed on the screen is automatically dialed.

6 is a flowchart illustrating a dialing method by searching for the last four digits of a phone number according to another embodiment of the present invention.

In step 609, the controller 52 initializes the variable MATCH_CNT to 0. In step 610, the controller 52 checks whether a numeric key is input. If the check result detects the input of the numeric key, in step 611, the controller 52 checks whether four digits (the last four digits of the telephone number) are input, and if not, returns to step 610. When the number key is input as many as four digits, the controller 52 searches for whether the last four digits of the phone numbers stored in the call list 55b of FIG. 1 match the four digits input by the user. If a match is found, the variable MATCH_CNT is incremented by 1 each time. When the search for the call list 55b is completed, in step 613, the controller 52 searches whether the last four digits of the telephone numbers stored in the telephone number memory table 54 of FIG. 1 match the four digits input by the user. At this time, if there is a match, the variable MATCH_CNT is incremented by '1' each time. After completing the search, in step 614, the controller 52 checks whether the variable MATCH_CNT is greater than '0'. If the result of the check is greater than '0', it is checked in step 615 whether the variable MATCH_CNT is '1'. If the check result is '1', the found phone number is one. In step 616, the controller 52 displays the phone number stored in the search information list 55c on the display unit 53. In operation 617, the key input unit 51 is scanned to check whether the user selects the displayed telephone number. As described above, in the case of a general telephone, a specific key determined in advance may be used, and a call key may be used in a portable wireless telephone. In this case, in step 618, the controller 52 controls the telephone number displayed on the display unit 53 to be dialed. If the user's selection is not detected in step 614 and if the variable MATCH_CNT is not greater than '0' in step 614, the process returns to step 610.

If the variable MATCH_CNT is not '1' in step 615, it is a case where there are several telephone numbers found. In this case, the controller 52 proceeds to step 619 and the controller 52 sorts the found phone numbers according to a specific condition. As described above, the specific condition is set in advance according to the application such as the frequency of dialing the telephone number or the order of the most recent dialing.

After the alignment, the variable i is set to '1' in step 620, and then in step 621, the variable MATCH_CNT and the phone number stored in the variable i th address among the sorted phone numbers are displayed on the display unit 53. The variable i represents the address of the search information list 55c in which the found phone number is stored. In the present embodiment, as shown in step 623, the address is sequentially increased by '1'. After that, if the user inputs a preset toggle key to view the next found phone number, the controller 52 detects this in step 622 and proceeds to step 623 to increase the variable i by '1' and then proceeds to step 620. Go back. If the input of the toggle key is not detected in step 622, the method proceeds to step 617 and checks whether the user selects the currently displayed phone number.

7 is a flowchart specifically illustrating a call list search or a phone number memory table search process of FIG. 6.

In step 710, the controller 52 sets the variable P to '1'. The variable P represents the address of the call list 55b or the telephone number memory table 55c. If the search is for a call list as shown in FIG. 2B, the variable P is 1 to 5, and if the search is for a phone number memory table as shown in FIG. 2A, the variable P is 1 to 100.

In step 711, the controller 52 checks whether a phone number is stored in the variable P address of the call list 55b or the phone number memory table 55c. If the phone number is stored in step 712, the last four digits of the stored phone number are read and compared with the four digits entered by the user. In operation 713, the controller 52 analyzes the comparison result to determine whether there is a match. In this case, in step 714, the controller 52 reads the phone number and stores it in the search information list 55c. In step 715, the controller 52 increases the variable MATCH_CNT by one.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

According to the present invention, when a user wants to dial by using a portable wireless telephone as well as a general telephone, a user who has previously registered or has previously made a phone call only needs to enter one or several digits of the desired telephone number.
