Convenient dialing of names and numbers from a phone without alpha keypad
First Claim
1. A method for operating a mobile communication unit having a database containing data records for one or more telephone numbers with each data record containing an index item stored by a character string, said method comprising:
- searching said database for an index item beginning with a desired character string; and
automatically switching said mobile communication unit to a normal telephone number entry mode if said database contains no data records having an index item potentially matching said desired character string such that additional characters can be appended to the desired character string without having to manually switch the mode of operation of the mobile communication unit.

Abstract
Retrieving a desired telephone number from a database in a mobile communication unit is facilitated by utilizing the frequency with which the user calls each telephone number stored in the database in a manner that allows the mobile communication unit to make a “best guess” of which phone number the user is seeking each time the user pushes a key while inputting a name or character string representing the person that the user wishes to call from the mobile communication unit. If the database does not include any name or character string potentially matching a desired character string entered via a keypad, the mobile communication unit automatically switches to normal phone number entry mode.

8. A method for placing a call using a mobile communication unit operable alternatively in database search mode of telephone number entry or a normal telephone number entry mode and having a display, a keypad having number keys and a scroll key for scrolling said display, a database for storing data records for telephone numbers with each data record containing a frequency with which said mobile unit calls each of said telephone numbers in said database and an index item stored by a character sequence, said method comprising:
-
inputting a desired character sequence using said number keys of said keypad;
searching said database in said database search mode for said index items matching said desired character sequence; and
automatically switching said mobile communication unit to normal telephone number entry mode if said database has no index items potentially matching said desired character string such that additional characters can be appended to the desired character string without having to manually switch the mode of operation of the mobile communication unit. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A mobile communication unit comprising:
-
a database storing data records for one or more telephone numbers with each data record containing a stored character string corresponding to each phone number stored in said database;
a keypad for inputting a desired character string; and
a controller for receiving said desired character string and searching said database in a database search telephone number entry mode for said data records having stored character strings beginning with said desired character string, and automatically switching said mobile communication unit to a normal telephone entry mode if said database does not contain any stored character string potentially beginning with said desired character string such that additional characters can be appended to the desired character string without having to manually switch the mode of operation of the mobile communication unit. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A mobile communication unit comprising:
-
a database storing data records for one or more telephone numbers with each data record containing a stored character string corresponding to phone numbers stored in said database and a frequency called value representing a frequency with which said mobile communication unit places a call to each said phone number stored in said database;
a keypad for inputting a desired character string;
a controller for receiving said desired character string and searching said database in a database search telephone number entry mode for said data records having stored character strings beginning with said desired character string, and providing a listing of data records identified by said searching of said database together with frequency called for each of said data records;
a screening circuit in said controller automatically switching said mobile communication unit to a normal telephone number entry mode if said database does not contain any data records beginning with said desired character string such that additional characters can be appended to the desired character string without having to manually switch the mode of operation of the mobile communication unit; a sorter for sorting said data records provided by said controller;
a display device for displaying a grouping of said data records in order as sorted by said sorter;
a selector for selecting a data record from said displayed grouping to be called by said mobile communication unit;
an incrementor for incrementing said frequency called in said data record for said telephone number called by said mobile communication unit each time said mobile communication unit calls said telephone number in said database, and a reset circuit for automatically resetting said mobile communication unit to said database search telephone number entry mode after completion of a call in said normal telephone number entry mode.
