Abstract

A method includes receiving input from a user via a keypad of the communication device and searching a database and a cache to identify a word or web site identifier based on the received input. The word or web site identifier may correspond to a word or web site identifier that the user intends to input. The method may also include providing the word or web site identifier via a display of the communication device.

Claims

1. In a communication device, a method comprising:

receiving input from a user via a keypad of the communication device;

searching a first database to identify at least one word or uniform resource locator (URL) based on the received input, the at least one word or URL corresponding to a word or URL that the user intends to input;

searching a cache to identify the at least one word or URL; and

providing the at least one word or URL via a display of the communication device.

2. The method of claim 1, further comprising:

accessing web sites based on input from the user; and

storing, in the cache, at least one of web site content or URLs associated with the accessed web sites.

3. The method of claim 1, wherein the providing comprises:

providing a plurality of words or a plurality of URLs that potentially correspond to information that the user is attempting to enter via the keypad, and

providing the plurality of words or plurality of URLs prior to completion of entry of the information by the user.

4. The method of claim 1, wherein the searching the cache comprises:

searching the cache based on at least two prior words of a message input by the user.

5. The method of claim 1, further comprising:

storing URLs in the cache for a predetermined period of time.

6. The method of claim 1, further comprising:

storing at least portions of web pages in the cache for a predetermined period of time.

7. The method of claim 1, wherein the providing the at least one word or URL comprises providing at least one of a plurality of words or a plurality of URLs, the method further comprising:

receiving a selection by the user corresponding to a first one of the words or a first one of the URLs;

storing the first word or first URL in the first database in response to the selection, the first database being a more permanent storage location than the cache; and

performing word recognition based on input from the user via a keypad based on information stored in the first database.

8. The method of claim 1, further comprising:

viewing a picture or image;

identifying a name or word associated with the picture or image; and

storing the identified name or word in the cache.

9. A communication device, comprising:

an input device configured to receive input from a user;

a first memory;

a cache;

a display; and

logic configured to;

search the first memory and the cache to identify at least one word or web site identifier based on the received input,

provide the at least one word or web site identifier via a display of the communication device,

receive a selection corresponding to the at least one word or web site identifier that was identified from the cache, and

store the selected at least one word or web site identifier in the first memory.

10. The communication device of claim 9, wherein the logic is further configured to:

perform word recognition using information stored in the first memory and the cache.

11. The communication device of claim 9, wherein when providing the at least one word or web site identifier, the logic is configured to provide at least one uniform resource locator (URL).

12. The communication device of claim 11, wherein the URL is associated with a web site accessed by the communication device.

13. The communication device of claim 9, further comprising:

a communication interface configured to access web sites via a network based on input from the user via the input device, and

wherein the logic is further configured to;

store web site identifiers and web site content associated with the accessed web sites in the cache.

14. The communication device of claim 13 wherein when storing the web site identifiers and web site content, the logic is configured to store the web site identifiers and web site content in the cache for a predetermined period of time.

15. The communication device of claim 14, wherein the logic is further configured to delete a first one of the web site identifiers and first web site content associated with the first web site identifier stored in the cache based on at least one of a duration of time that the first web site identifier and the first web site content have been stored in the cache or lack of selection by a user via the input device corresponding to the first web site identifier or first web site content.

16. The communication device of claim 9, wherein the cache is further configured to store images or pictures and the logic is further configured to:

identify a name or word associated with the picture, and

store the identified name or word in the cache.

17. The communication device of claim 9, wherein the cache comprises an index of words associated with information stored in the communication device.

18. The communication device of claim 9, wherein the at least one word or web site identifier comprises at least one of a plurality of words or a plurality of web site identifiers associated with information accessed by the communication device.

19. The communication device of claim 9, wherein the input from the user comprises at least a portion of a message and when searching the cache, the logic is configured to:

search the cache to identify the at least one word or web site identifier based on at least two previous words of the portion of the message.

20. The communication device of claim 9, wherein the input from the user comprises at least a portion of a message and when searching the cache, the logic is configured to:

search the cache to identify the at least one word or web site identifier based on a previous word of the portion of the message, the previous word being located at least two words prior to the at least one word or web site identifier.

21. The communication device of claim 9, wherein the communication device comprises a mobile terminal.

22. A computer-readable medium having stored thereon sequences of instructions which, when executed by at least one processor, cause the at least one processor to:

receive input from a user via an alpha-numeric keypad;

search a first database including information accessed by the user to identify at least one potential word or identifier which the user intends to input; and

provide the at least one potential word or identifier to the user via a display.

23. The computer-readable medium of claim 22, further comprising instructions for causing the at least one processor to:

access information via a network in response to input from the user; and

store at least some of the accessed information in the first database.

24. The computer-readable medium of claim 22, her comprising instructions for causing the at least one processor to:

store web site identifiers and web site content in the first database, the web site identifiers and web site content being associated with web sites accessed by the user.

25. The computer-readable medium of claim 22, further comprising instructions for causing the at least one processor to:

receive selections from the user corresponding to words and identifiers provided via the display and that were identified from the first database; and

store the selected words and identifiers in a second database, the second database corresponding to a more permanent database than the first database.

26. A communication device, comprising:

an alpha-numeric keypad configured to receive input from a user;

a display;

a first memory configured to store information associated with web sites or documents accessed by the communication device;

a second memory configured to store a database; and

logic configured to;

search the first memory and the second memory to identify at least one word or web site identifier based on the received input, and

provide the at least one word or web site identifier via a display of the communication device.

27. The communication device of claim 26, wherein the logic is further configured to:

receive a selection corresponding to the at least one word or web site identifier provided via the display, and

store the selected at least one word or web site identifier in the database, wherein the database represents a more permanent storage location than the first memory.
