Abstract

A method of dialing a phoneword using a mobile communication device that has full keyboard, which maps numbers to letters differently than on standard telephone keypads. The method detects the prefix of the phoneword and proceeds to display a message on the mobile communication device to indicate that a pre-determined key needs to be pressed before entering letters of the phoneword. The method can also display for selection, candidate phonewords that correspond to a partial entry of the phoneword.

First claim

What is claimed is:

1. A method of dialing a phoneword using a mobile communication device, the mobile communication device having a keyboard comprising a plurality of keys, the phoneword having a numerical beginning sequence and a remainder sequence, the remainder sequence having associated numbers thereto, at least one of the numbers having an associated letter, the method comprising:
detecting input by the keyboard of a phoneword, the input comprising receiving a number at the keyboard;
and
in response to the detection of the input by the keyboard of the phoneword, displaying a prompt in a display of the mobile communication device to complete input of the phoneword by performing an operation on the keyboard comprising identifying a letter associated with the number to enable entry of one or more letters of the phoneword in lieu of corresponding numbers;
constructing partial candidate phonewords in accordance with:
the numerical beginning sequence;
the number; and
the letter associated to the number; and
comparing the partial candidate phonewords with known phonewords to obtain candidate phonewords; and
displaying for selection, on the mobile communication device, the candidate phonewords, the displaying for selection preceded by ranking the candidate phonewords to obtain ranked candidate phonewords and the displaying for selection including displaying, as a function of rank, the ranked candidate phonewords.

2. The method of claim 1 wherein:
the prompt is a message indicating the operation to perform.

3. The method of claim 2 wherein the operation includes pressing a key of the keyboard.

4. The method of claim 1 wherein ranking the candidate phonewords includes ranking the candidate phonewords as a function of a number of calls placed to each candidate phoneword.

5. The method of claim 1 wherein comparing the partial candidate phonewords with known phonewords is preceded by accessing a database of phonewords.

6. The method of claim 1 further comprising:
providing the partial candidate phonewords to a comparison module; and
receiving, from the comparison module, candidate phonewords that match the partial candidate phonewords.

7. The method of claim 6 further comprising displaying for selection, on the mobile communication device, the candidate phonewords.

8. A method of dialing a phoneword using a mobile communication device, the mobile communication device having a keyboard comprising a plurality of keys, the phoneword having a numerical beginning sequence and a remainder sequence, the remainder sequence having associated numbers thereto, at least one of the numbers having an associated letter, the method comprising:
detecting input by the keyboard of a phoneword;
and
in response to the detection of the input by the keyboard of the phoneword, displaying a prompt in a display of the mobile communication device to complete input of the phoneword by performing an operation on the keyboard to enable entry of one or more letters of the phoneword in lieu of corresponding numbers.

9. The method of claim 8 wherein:
the prompt is a message indicating the operation to perform.

10. The method of claim 9 wherein the operation includes pressing a key of the keyboard.

11. The method of claim 8 further comprising receiving a number at the full keyboard.

12. The method of claim 11 further comprising identifying a letter associated with the number.

13. The method of claim 12 further comprising constructing partial candidate phonewords in accordance with:
the numerical beginning sequence;
the number; and
the letter associated to the number.

14. The method of claim 13 further comprising:
comparing the partial candidate phonewords with known phonewords to obtain candidate phonewords; and
displaying for selection, on the mobile communication device, the candidate phonewords.
