Abstract

Network logical addresses are converted to temporary addresses which are more easily input using keys, typically ten keys, of mobile phones. Each character of the original address is replaced by a numeral, the numeral key being assigned to the character. In a certain phone, for example, key “2” is assigned to “2”, “A”, “B” and “C” and key “3” is assigned to “3”, “D”, “E” and “F”. If the original address includes “CE” as part of it, these two characters are converted simply to “23”. In the preparation step, the original addresses of web sites are converted to temporary addresses and the relation between them is registered in a table. By referring to the table, it would be easy to translate a temporary address to its original address so that correct access to the target site is enabled.

Claims

1. A network logical address conversion method comprising:

obtaining an inputted temporary logical address; and

searching for a real logical address corresponding to the inputted temporary address,

wherein the search is conducted on the assumption that at least part of the inputted temporary address has been generated by replacing each character of the real logical address with a numeral assigned thereto in an information terminal.

4. The method of claim 1, further comprising indicating a highly probable candidate as an expected real address when a plurality of real addresses are found in the search.

2. A network logical address conversion method comprising a preprocess and a main process,

wherein the preprocess comprises:

obtaining an inputted real logical address,

identifying numerals, each thereof being assigned in an information terminal to each character of the inputted address;

generating a temporary logical address corresponding to the real address by replacing at least some of the characters with the identified numerals; and

storing the generated temporary address, and

wherein the main process comprises;

obtaining an inputted temporary address; and

searching for a real address corresponding to the inputted address in the set of stored temporary addresses.

3. The method of claim 2, wherein the search comprises detecting in the set a temporary address which is equal to the inputted temporary address, and identifying a real address from which the detected temporary address has been generated.

5. The method of claim 2, further comprising indicating a highly probable candidate as an expected real address when a plurality of real addresses are found in the search.

6. An network address conversion apparatus comprising:

a first address obtaining unit which obtains an inputted real logical address;

a converter which converts the inputted address to a corresponding temporary address;

a table which stores the inputted real address with the temporary address linked thereto;

a second address obtaining unit which obtains an inputted temporary logical address; and

a search unit which searches for a real logical address corresponding to the inputted temporary address;

wherein the converter identifies a numeral assigned to a key of an information terminal, the key being used to input a character of the real address, the character corresponding to the numeral, and generates the temporary address corresponding to the real address by replacing at least some of the characters of the real address with the identified numerals.

7. The apparatus of claim 6, further comprising a candidate processor which, when a plurality of real addresses capable of corresponding to the temporary address have been found by the search unit, indicates the found real addresses in a manner such that a higher probability candidate is listed with priority.

8. The apparatus of claim 6, further comprising a charge unit which charges for service processed by the search unit and/or the converter.

9. The apparatus of claim 7, further comprising a charge unit which charges for service processed by the search unit and/or the converter.

10. The apparatus of claim 6, further comprising an address classifier which judges whether the logical address obtained by the second address obtaining unit is a temporary address and which initiates the search based on the judgment.

11. The apparatus of claim 7, wherein the candidate processor comprises a general priority processor which indicates the same set of candidates to different users.

12. The apparatus of claim 11, wherein the general priority processor presents with priority a real address having a larger number of accesses thereto.

13. The apparatus of claim 7, wherein the candidate processor comprises a user-dependent priority processor which indicates a different set of candidates to a different user.

14. The apparatus of claim 13, wherein the user-dependent priority processor presents with priority to a user a real address having a larger number of accesses thereto by the user.

15. The apparatus of claim 7, wherein the apparatus is implemented in an Internet service provider.

16. The apparatus of claim 7, wherein the real address is a Uniform Resource Locater.

17. The apparatus of claim 7, wherein the temporary address is a series of numerals assigned in an informational terminal to respective keys used to input respective characters of the real address.

18. A network address conversion apparatus comprising:

a table storing correspondence between temporary logical addresses and real logical addresses;

an address obtaining unit which obtains an inputted temporary address; and

a search unit which searches for a real address corresponding to the inputted temporary address in the table,

wherein at least part of the inputted temporary address has been generated by replacing each character of the real logical address with a numeral assigned thereto in an information terminal.

19. A network address conversion method comprising:

obtaining an inputted temporary logical address;

identifying a set of characters for each digit of the temporary address, the set of characters being assigned to a key of an information terminal used to input the digit;

obtaining a group of addresses including the real address by arranging the identified sets of characters; and

selecting the real address out of the group as an intended real address.
