Abstract

A method of providing wireless Internet service in a gateway system having a conversation function according to short messages includes storing and managing the latest URL web contents in a URL memory using the TTL, expire time and last modification time for URL web contents. Web contents corresponding to URL information requested by a mobile terminal are parsed and stored in a cache, and then transmitted to the mobile terminal through I-SMSC. The service method stores and manages the latest URL web contents in the URL memory using the TTL, expire time and last modification time for URL web contents to directly access the Internet. Thus, the service method provides the URL web contents to the mobile terminal when there is a request for URL information from a mobile terminal supporting no WAP standard for URL information which does not exist in the URL memory. Accordingly, quick Internet service for the last web contents is available, and in case of an update of bookmarked URL information defined by a subscriber, it is possible to inform the subscriber of the updated URL information.

performing access through the Internet to collect the latest web contents corresponding to the selected records; and

updating the first validity time of each of the selected records whose first validity time is defined among the collected web contents.

2. The method of claim 1, wherein the searching records determines whether a current time has been passed the first validity time when the first validity of the record is designated and determines whether the second validity time is available when the first validity time is not designated.

3. The method of claim 1, wherein when the first validity time of the record has not been passed or the second validity time is available, a last access time of the corresponding record is updated to a current time.

4. The method of claim 1, wherein performing access through the Internet to collect the latest web contents corresponding to the selected records comprises updating the second validity time of the selected record in the collected latest web contents whose first validity time is not designated.

5. The method of claim 4, wherein the updating the second validity time of the selected record in the collected web contents comprises calculating the second validity time to update the second validity time of the selected record when the last modification time of the collected web contents is changed, and initializing the first validity time and calculating a new second validity time of the selected record when the last modification time of the collected web contents is not changed.

6. The method of claim 1, wherein the updating the first validity time of each of the selected records whose first validity time is designated among the collected web contents comprises updating the first validity time, the second validity time and a last modification time when the last modification time of the collected web contents is changed, and the first validity time is updated when the last modification time is not changed.

7. The method of claim 1, wherein the step of packaging selected web contents corresponding to the web information requested by the mobile terminal comprises:

updating parameters of a requested service session upon connection;

analyzing an identification number of the web information requested for receiving Internet service to determine if the request is for processing a first menu;

searching for a prescribed key included in the requested web information to determine if the prescribed key exists in the memory when the request is not for processing the first menu;

reading the web contents stored in a corresponding record when the prescribed key exists in the memory; and

packaging the read web contents from the corresponding record and storing them in a second memory.

9. The method of claim 7, wherein the searching for the prescribed key confirms when the prescribed key exists in an inner cache of the memory, the prescribed key exists in a URL database.

10. The method of claim 7, wherein when the request is for the first menu processing as determined by a URL identification number of the requested web information, the web information is generated to be transmitted through one of a bookmark processing, a system menu processing, an electronic mail processing, and a user input processing routines according to the identification number.

11. The method of claim 1, wherein the mobile terminal does not support a standardized process for the Internet and the Intranet access.

12. The method of claim 11, wherein the mobile terminal does not support a wireless application protocol and browser.

8. The method of 7, wherein when the prescribed key does not exist in the memory, the packaging selected contents comprises performing access through the Internet to collect the selected web contents, packaging the collected web contents and storing them in the second memory.

13. A radio communication system, comprising:

a mobile terminal that does not support a first protocol;

a web server coupled to provide access to an Internet connection; and

a gateway system that provides corresponding web contents from one or more of an Internet access and an Intranet access using the first protocol while communicating with the web server, and provides the corresponding web contents to the mobile terminal using a second protocol, wherein the corresponding web contents are responsive to a request from the mobile terminal, wherein the gateway system comprises,

a memory comprising validity time records,

a content manager that calculates whether said validity time records are valid, and

an internet managing device that collects web contents if said time validity records are invalid, wherein said content manager updates said validity time records when said interact managing device collects web contents.

14. The radio communication system of claim 13, wherein the mobile terminal does not support a wireless application protocol and a browser, and wherein the gateway system using the second protocol provides the corresponding web contents to the mobile terminal upon receipt of the request.

20. The radio communication system of claim 13, wherein said validity time records comprise:

a first time record corresponding to a time when said corresponding web contents expire based on corresponding web contents information; and

a second time record corresponding to a preset time when said first time record is not provided by said corresponding web contents information.

21. The radio communication system of claim 13, wherein said gateway system updates parameters of a requested service session upon connection between said web server and said mobile terminal;

wherein said gateway system generates a corresponding session identification number which is analyzed to determine if a web information requests for receiving internet service is for processing a first menu;

wherein said content manager searches for a prescribed key included in a requested web information to determine if the prescribed key exists in the gateway system when the request is not for processing the first menu;

wherein said gateway system reads web contents stored in a corresponding record when the prescribed key exists in the gateway system; and

wherein said content manager packages the read web contents from the corresponding record and stores them in said gateway system.

22. The method of claim 13, wherein said gateway system accesses a network common carrier upon receipt of a session connection request from the mobile terminal to confirm an identification of the mobile terminal and update session parameters;
