Description

How to store your phone number and various search methods {.}

The present invention relates to a method for storing and retrieving a phone number. More particularly, the name (or phone number) is scrolled by the number of lines in the display window every time the scroll key is pressed in the phone number search so that the user can quickly search the phone number. By using a special function key, the minimum number of key operations can be performed, the phone book and the recent call list DB can be integrated, and the memory address of the storage address and the search method using the list of 'storage address' will be.

In general, a phone number can be searched by scrolling one record at a time using the scroll key or displaying several name or phone number data on the display window, and each time the scroll key is pressed, the point moves one by one. Display several phone numbers again and continue searching in the same way. Thus, for example, the 20th telephone number is inconvenient to be selected by pressing the scroll key 20 times.

In addition, in order to perform a specific function, it is inconvenient to press the 'Menu' or 'Search' key and then press several selection numbers and scroll keys until the desired function is performed. Enter a phone number, make a call, and then call a recent call. It is inconvenient to limit the effective way of entering or modifying only one field, such as the name, in the record of the list.

The recent call list and phone book DB are kept separately, so the same phone number is stored in double, which wastes memory, and it is necessary to specify the DB to be searched when searching. When searching by phone number or name, both data cannot be searched at the same time. There is inconvenience.

In order to solve the above problems, the present invention, when pressing the scroll key once, scrolls the name (or phone number) by the number that can be displayed on the display window, so that you can select the desired data, and use a special function key To execute the desired function with the minimum number of key operations, and integrate the phone book and the recent call list DB into one, to search the entire stored data when searching, and to create a field to record the memory status of the storage address, It is an object of the present invention to provide various phone number retrieval methods using a list of storage addresses.

In order to achieve the above object, the present invention determines the number of data that can be displayed per screen according to the number of lines of the display window, the number of characters per line, and the length of the data to be searched. Scroll by as much data as possible. For example, if the screen is 4 lines and displays two names per line, the screen can display a total of 32 characters in 4 lines of 8 characters, 1, 9, 17, 25, 5, 13, 21, 29 Display the selection number in the character position in the order of 1 :, 2 :, 3 :, 4 :, 5 :, 6 :, 7 :, 8 :, followed by the first 3 letters of the name, that is, 6 bytes It provides a "screen unit search method" that scrolls eight names each time the scroll key is pressed. When the name you want appears, press the selection number to select it.When data is selected, the name, phone number, etc. are displayed in record units by the existing method. From then on, scroll by one record.

To minimize the keystrokes required to execute a particular function, create a special function key, such as the 'Num Lock' key on the top of the existing computer's numeric keyboard. Pressing this function key indicates that the key has been entered in the register and on the display. In this state, pressing a number key or other keys on the keypad allows you to execute a specific function immediately.

The phone book and recent call list DB are integrated into one, create a field to record the memory status of the storage address, and provide a method of searching various phone numbers and applying various search conditions simultaneously using the list of 'storage address' In addition, the recent call list function is characterized by the implementation of the list of 'storage address'.

One record is displayed on one screen, and when the scroll key is pressed once, the existing search method of moving a point by one is the 'record unit search' method. In the screen unit search method, when the number of target records to be searched is large (for example, three or more), pressing the scroll key displays the name (or necessary data) as many as the displayable number along with the selection number on one screen. Once a name is selected by pressing the selection number, it switches to the existing record unit search method. If there are only one record or number of records to be searched, the existing 'search by record' method is displayed.

When searching by screen unit, the number of data to be displayed per screen and the position of selection number (for example, 32 characters can be displayed in 4 lines of 8 characters each, 1, 9 when displaying 4 names per screen) If you want to display the selection number 1 :, 2 :, 3 :, 4: at the positions of characters 17, 25, and 8 each, the positions of characters 1, 9, 17, 25, 5, 13, 21, 29 Check the selection number in the order of 1 :, 2 :, 3 :, 4 :, 5 :, 6 :, 7 :, 8 :), position the point on the first record to be displayed on the screen, and Store the location in the register, and then display the data after the selection number in turn. (If four names are displayed per screen, seven characters are displayed from the first character, that is, 14 bytes. After the first three letters of the name (ie, 6 bytes each), the point is placed on the first data on the screen.

Next, when the input number is entered according to the selection number input, scroll key input, end key input, etc., the point is moved by the number minus 1 from the selection number, and the selected record is renamed as in the conventional method. Display the number, etc. on the screen, switch to the record unit search method, move the point by the number of data displayed per screen when scroll key is input, and then display the data on the screen as above. Exit and return to the first screen.

If the data displays multiple data on one line like Hangul consonants or vowels, first select the line with the selection number, then mark the selected line with an arrow, etc. Display the selection number up to 9 as a single digit. At this time, the point is located at the initial data of the display window. When a line is selected, the point is moved by (line number-1) x the number of data per line, and when the data is selected, the point is moved by the number minus 1 from the data selection number.

The first letter of the data is the numbers 1, 2, 3,. . . , 9, 0 in order, and if the number of records is 10 or less like 'index name by index number', this number is used as the selection number, and the point moves the record by the pressed number from 1 to 9. Press 0 to move to the 10th record.

Data selection number is used for data selection and point movement. Button shape for easy identification Enter a number inside or do something like '1:' and use a single digit on the keypad.

When searching by the screen unit, since there is no one specified record, the function keys such as 'Save' and 'Delete' cannot be used, and only the keys such as scroll key, selection number, and 'end' can be used.

To minimize the keystrokes required to perform a particular function, a special function key such as the 'Num Lock' key on the top of the keyboard of an existing computer is used for the 'F' (Function key) and 'Id' (index key). Create a special key. This special function key allows you to execute a specified function immediately according to the next key combination and the combination of the same key.Also, you can execute the necessary functions for each distinguishable state such as initial screen state, record unit search state, and edit state even with the same key combination. do.

Pressing this special key indicates that this special key has been entered in the register and display window, and waits for the next key input. If a certain number of seconds pass without inputting the next key, the special key setting is automatically released to deal with accidental pressing.

When one key is pressed, the function key input status is judged first.If the function key is input status, the current status such as initial screen status, record unit search status, edit status, etc. After releasing the input state of the special function key, perform the function to execute. If the special function key is not input, the original function of the key is executed.

Function setting using special function key is as follows.

Use function keys in initial screen state (example)

○ Search directly with special function keys

'Id' + '1': Business relationship. 'Id' + '2': Social, workplace friend

'Id' + '3': Family, relative 'Id' + '4': School, military friend

'Id' + '5': Hometown friend. 'Id' + '6': nearby stores

'Id' + '7': Faith, hobby 'Id' + '8': Government office, weather

'Id' + '9': E_mail, Domain 'Id' + '0': No index

'F' + '1': Call list 'F' + '2': Priority

'F' + '3': First name of each screen 'F' + '4': First consonant search

'F' + '5': First letter search 'F' + '6': Search by region

'F' + '7': Save, edit required 'F' + '8': Full name

'F' + '9': Enter name. 'F' + '0':

○ Set search conditions only

'Id' key + scroll key: Search / set the indes name by screen unit

'F' key + scroll key: Search / set search condition of F key by screen unit

'Set search condition' is to set the frequently used search method, so that if you press the scroll key, the search will be performed with the set condition immediately.The 'Search directly with special function key' function will be valid regardless of the set search condition. .

○ Changing Search Criteria

'Id' key + 'Id' key: Toggles the search condition between the index setting and the search condition by the 'F' key, even if the search condition set by the 'F' key and the search condition by the index are toggled. It maintains the condition before the change and returns to the previous search condition if there is input of 'Id' key + 'Id' key again.

○ Other features

'Id' + 'F': Edit selected index name

If you are not familiar with how to use the function keys in the initial screen, search the phone number as above.If you are not skilled, use the "Search immediately with special function keys" function as "Setting search conditions." When searching, the user can search by using the scroll key while the condition is set. At this time, the function of setting the search condition is also provided to serve as a help function.

Each set search condition is displayed on the screen as text, for example, '1: business relationship', so that the currently set search condition can be confirmed.

Use function keys in screen unit search (example)

'F' + 'F': Specify 4 and 8 toggles of name display per screen when searching unit name

Using function keys in record unit search (example)

'F' + 'F': Returns to the screen unit search status (when changing from screen unit to record unit)

'Id' + 'Number': Enter index number 'F' + '1': Edit name

'F' + '2': Edit phone number 'F' + Scroll key: Display special function key usage screen

In the record-by-record state, use special function keys to enter or modify data only in the fields you want. In this case, edit the data directly on the screen or save the current screen to temporary memory and return to the original screen after editing.

Specifying the input character with the function key when editing the text field (example)

'F' + 'F': Toggle input character 'F' + '1': Uppercase alphabetic characters

'F' + '2': Lowercase alphabet 'F' + '3': Arabic numerals

'F' + '4': Hangul input 'F' + '5': Special characters

'F' + scroll key: Displays function key usage screen when editing text fields

In this case, various character types necessary for editing can be changed immediately, so the number of key manipulations required for character editing is minimized, and only numbers are input when editing a field for storing numbers such as telephone number input.

In each state, 'F' + scroll key provides the information needed to use the special function key and operate the key in screen unit search method to provide help function.

The difference between the recent call list and the phone book is that, first, the recent call list deletes the oldest record and stores a new number when the number of records is exceeded, whereas the phone book is not stored when the number is exceeded. Therefore, the recent call list has the characteristic of 'temporary' stored number, and the phone book has the characteristic of 'stored' phone number. Second, the recent call list is the calling order, and the phone book does not change the input order.

It integrates the recent call list and the phone book database into one and creates a field to record the 'memory status' to distinguish the stored phone numbers into 'temporary' and 'save'. The memory state is stored as 'N' for 'Null', 'T' for Temporary, 'S' for 'Save', and 'T' temporarily stores the number called. 'S' is a state in which a phone number is entered or the number 'T' is stored by pressing the 'save' key. That is, 'N' is an empty memory, 'T' is a list of existing recent calls, and 'S' is a state of storing data of the existing phone book.

If you change the 'Memory Status' from 'T' to 'S', it is saved by pressing the 'Save' key. If you change 'T' or 'S' to 'N', it is deleted. To save a new phone number, search for 'Storage Address' with 'Memory Status' 'N', change it to 'S', and save the phone number here.

The recent call list is a list of the 'storage addresses' that are called. If you call the unsaved number, find 'S' in 'N', change it to 'T', save the phone number, and save this number at the head of the recent call list 'Storage Address' list. Add When you search or enter a number in the phone book and call, change the location only to the front if the address is in the 'storage address' list of the recent call list, and add the 'storage address' if it is not. If a new 'Storage Address' is added to the recent call list 'Storage Address' list, it excludes the 'Storage Address' exceeding the specified number.If the 'Memory Status' of the 'Storage Address' to be excluded is 'T', 'N' Change to and exclude from the list. If 'S', leave the memory as it is, and exclude from the list only.

When searching the recent call list, the name of the storage address is displayed on the display window in the order of the 'Storage address' list, and if there is no name, the phone number is displayed. In addition, if the memory status is 'T', it displays 'Temporary' on the screen so that it can be stored when needed.

As a way to save memory, if the storage address is 1 byte in size, it is possible to manage up to 256 phone numbers because the total number of cases is 256 with 8 bits, and the number of 4 cases with 2 bits is also available in the 'Memory Status' field. 3 memory states can be distinguished and saved.

In the method of searching for a phone number, such as creating a list of storage addresses of recent call lists, make a list of phone numbers corresponding to a specific condition and a list of 'storage addresses' according to the order to be displayed on the screen when searching. When searching for a phone number, the data is retrieved from the corresponding storage address record in the phonebook DB by the type and number of data to be displayed on one screen, in the order of the 'storage address' that meets the conditions, according to the set search condition. As a way of displaying, 'search the phone number by the storage address list.

The 'Storage Address' list creates and stores a storage address DB, and creates fields to store record numbers, alphabetical order, ascending order, search priority, and index number, and records as many as the number of phone numbers that can be stored. Record numbers are sequentially 1, 2, 3,. . . , In order of 199, 200, and in the name alphabetical order field, make a list of 'storage address' and save them in order, and the number ascending field sorts phone numbers in ascending order to make 'storage address' list. Save address in order and store search priority and index number in order.

When searching the entire name in alphabetical order, the name of the storage address DB is provided as a screen unit search method in the order of 'storage address' in the alphabetical storage address field.

When searching by first consonant name, the starting record number and last record number are saved by the first consonant in the list of full name alphabetical storage address, and the first consonant is selected by screen unit search method. Only the names of the storage addresses in the range of records that have a record are searched in sequence.

When searching by name, save the starting record number and the last record number by the first letter in the list of all names in the alphabetical storage address list, and select the first letter as the screen unit search method. Only the names of the storage addresses in the range of records that have a record are searched in sequence.

In case of searching by 'first name of each screen', the records with the selection number 1 of each screen when searching by full name alphabetically, namely 4 names per screen, the record number of storage address DB is multiple of 4 + 1 ( 1, 5, 9, 13, 17,...), And the name of the storage address. If you search 8 names per screen, the record number is a multiple of 8 + 1 (1, 9, 17, 25, 33). It is a method to provide the name of the storage address, which is the number of address, as the screen unit search method, and when one name is selected, the point is moved to the corresponding record number, and the search is performed by the screen unit search method from there. This method allows you to skip several screens at once in the screen unit search method. If you display 8 'first names per screen' per screen, you will be provided with the alphabetical search key for a total of 64 records. The name can be selected by three or four key inputs with two scroll keys, 'first name by screen' selection number, and the desired name selection number on the corresponding screen. At this time, the shape of the selection number is changed so that 'first name by screen' search and screen unit search after screen selection can be distinguished.

When searching phone numbers by region / communication company, save the starting address number and last record number by region, communication service provider, and save the list of 'storage address' in the ascending field of the 'storage address' DB. If you select the operator number (eg Seoul, 017) as the screen unit search method, only the names of the storage addresses in the record range with the corresponding number are searched in order.

The record range information for each region / telephone number by phone number is determined by the first three digits when the telephone number is entered, and the telephone directory is searched for only the phone numbers of the storage addresses in the record range. If it is a new number, stored number, or stored number, check whether the 'Memory Status' is 'T' or 'S'.

Search Priority According to Number of Calls Make a 'Storage Address' list. This creates a separate database with two fields for storing 'storage address' and 'call number', 'storage address' of each phone number in the 'storage address' field, and 'calling number' field. Accumulate the number of calls. After the specified total number of calls or a certain period of time, make a separate list of search priority 'storage address' according to the number of calls, save it in the search priority field of 'storage address' DB, and then use the number of 'usage' and total number of calls. And accumulate the new period. When searching, search by screen unit name in the 'storage address' order stored in the search priority field.

When entering a phone number, store the index number as a single digit, create a 'storage address' list for each index number, store it in the index number field of the 'storage address' DB, and then start the record number and the last record number for each index number. In the search, only the names of storage addresses in the record range with the corresponding index number are searched in order. Index number is used from '1' to '9', and '0' is used to search for numbers that do not have an index. Therefore, '0' is set when the search condition is set, but '0' is not input when storing the index in the telephone number record.

The 'Saved Address' list can be used to provide various search methods, as well as to combine two search conditions. For example, if the index number of the recent call list is searched for 3, compare the storage addresses in the recent call list 'storage address' list one by one to the 'storage address' list of index number 3. Only save addresses are listed in order.

1. It is inconvenient to press the 'Menu' or 'Search' key to perform a specific function, and to press the selected number and scroll key several times until the desired function is performed. Function can be performed immediately. In addition, as a combination of special function keys and the rest of the keys can be provided, a number of functions can be provided, so that only one field can be edited, such as input or modification, even while searching in record units.

2. It provides help function by using special function key and scroll key or other key, and can execute the desired function directly in the help status so that various functions can be utilized even without the manual.

3. When searching by 'First Name by Screen', if the first name of each screen is displayed on one screen, it is a search key for 64 names, and the 'First Name by Screen' key on the three screens totals 192. It is a search key for dog names. Since the names are arranged in alphabetical order, if you select the desired name by searching the dictionary, eight names of the screen are displayed immediately, and pressing the selection number selects the telephone number, so scrolls 192 names one or two times. It is possible to search by 3 ~ 4 key inputs with 2 times of name selection number.

4. Since the recent call list and phone book are in separate DBs, the same phone number is stored in duplicate and memory is wasted. When searching, the recent call list or phone book must be specified. It was not possible to search both data at the same time, but by integrating the two data, it was possible to prevent memory wastage, and when searching for names or phone numbers, it was unnecessary to specify the data to be searched.

5. Recent call list function using 'memory status' and 'storage address' list, search priority by search priority according to 'call count', search function by first consonant name, search function by region designation, index number Various search methods such as search function by designation and combination of two search conditions are provided with minimum memory. The memory required for one search method is the address number of the 'storage address' list x the number of bytes of one storage address (1 to 3 bytes). In addition, there is no need to physically move the location of the telephone number record, which reduces the work requirements of the process.
