Character input method and mobile communication terminal using the same
First Claim
1. A character input method for a mobile communication terminal, comprising:
- finding, in response to input of a key in a character input mode, at least one mapping of the key;
creating, if the key has at least two mappings, a string selection list containing strings of characters mapped by the mappings;
displaying the string selection list; and
displaying, if one of the strings in the string selection list is selected, the selected string in an input window,wherein, for each one of the strings of characters mapped by the mappings, all of the characters within the one of the strings correspond to a same kind of mapping, andwherein each kind of mapping maps at most one character to each key of the mobile communication terminal,wherein in creating the string selection list, in response to successive input of keys having at least two mappings, strings of mapped characters corresponding to individual kinds of mappings are created, wherein the string selection list containing the strings of mapped characters is generated,wherein the creating a string selection list step further comprises;
extracting, if a digit string is present among the strings of mapped characters, a phone number containing the digit string from a pre-stored phonebook;
extracting a name associated with the phone number; and
inserting the extracted phone number and name into the string selection list, andwherein the extracted phone number and the extracted name are inserted into the string selection list as separate selectable entries within the string selection list.

Abstract
A character input method and a mobile communication terminal using the method. The character input method includes: finding, in response to input of a key in a character input mode, at least one mapping of the key; creating, if the key has at least two mappings, a string selection list containing characters mapped by the mappings; displaying the string selection list; and displaying, if one of the strings in the string selection list is selected, the selected string in an input window. As a result, the user can conveniently input various pieces of information mapped to keys, including letters and numbers, to a mobile communication terminal without switching of input modes.

8. A mobile communication terminal comprising:
-
an input unit comprising a plurality of keys, each key having at least one mapping; a key mapping memory for storing the mappings of the keys; a controller for finding, in response to input of a key, a mapping of the key from the key mapping memory, and for creating, if the key has at least two mappings, a string selection list containing strings of characters mapped by the mappings; a phonebook memory; and a display unit for displaying a mapped character of the key and the created string selection list, wherein, for each one of the strings of characters mapped by the mappings, all of the characters within the one of the strings correspond to a same kind of mapping, and wherein each kind of mapping maps at most one character to each key of the mobile communication terminal, wherein in response to successive input of keys having at least two mappings, the controller creates strings of mapped characters corresponding to individual kinds of mappings, and generates the string selection list containing the strings of mapped characters, wherein, if a digit string is present among the strings of mapped characters, the controller extracts a phone number containing the digit string and a name associated with the phone number from a phonebook stored in the phonebook memory, and inserts the extracted phone number and name into the string selection list, and wherein the extracted phone number and the extracted name are inserted into the string selection list as separate selectable entries within the string selection list. - View Dependent Claims (9, 10, 11, 12, 13, 14)
