wherein the AP receives the advertisement service information including the update information for authentication information and AP information for connection to the AP from an information server connected to the AP, and

wherein the information server includes a first server that provides the advertisement service information including the update information for authentication information and a second server that provides the AP information for connection to the AP.

3. The electronic device of claim 1, wherein the controller is configured to send a request for an advertisement service to an AP identified by the short-range communication unit;

extract URL information for downloading authentication information from advertisement service information received from the AP in return for the request for the advertisement service and display the URL information;

access the URL upon selection of the URL information;

download the authentication information; and

make a connection to the AP based on the downloaded authentication information.

4. The electronic device of claim 1, wherein the controller is configured to send a request for an advertisement service to an AP identified by the short-range communication unit;

extract URL information for downloading authentication information and connection information to a public AP from advertisement service information received from the AP in return for the request for the advertisement service and display the URL information;

connect the electronic device to the public AP based on the information relating to connection to the public AP upon selection of the URL information;

access the URL by connecting to the public AP and download the authentication information;

disconnect the public AP and the electronic device; and

connect the electronic device to the AP based on the downloaded authentication information.

5. The electronic device of claim 1, wherein the controller is configured to send a request for an advertisement service to an AP identified through the short-range communication unit, the request including user information;

extract URL information to download authentication information from advertisement service information received from the AP in response to the request for the advertisement service based on a validation of the user information, and display the URL information;

access the URL upon selection of the URL information;

download the authentication information; and

connect the electronic device to the AP based on the downloaded authentication information.

6. The electronic device of claim 5, wherein if the user information is not valid, the controller is configured to receive advertisement service information that does not include URL information for downloading the authentication information from the AP in return for the request for the advertisement service.

7. The electronic device of claim 5, wherein the user information includes at least one of an ID valid for a venue where the electronic device is located and an unique ID of the electronic device, and

wherein whether the validation of the user information is determined based on whether the user information exists in a database (DB) of an information server connected to the AP.

8. The electronic device of claim 1, wherein the controller is configured to send a request for advertisement service to an AP identified by the short-range communication unit;

detect venue information from advertisement service information received from the AP in return for the request for the advertisement service and determine whether there is stored authentication information that matches the venue information; and

connect the electronic device to the AP using the authentication information stored if the stored authentication information matches the venue information.

9. The electronic device of claim 1, wherein the controller:

sends a request for the advertisement service to a first AP controller at the AP; and

sends a request for service information to a second AP controller at the AP, wherein the second controller provides Hotspot 2.0 functionality.

10. A method for updating authentication information in an electronic device, the method comprising:

detecting update information for authentication included in advertisement service information received from a identified Access Point (AP) identified by a short-range communication;

obtain authentication information using the update information, wherein the authentication information comprises an access password, and wherein obtaining the authentication information using the update information further comprises;

extracting Uniform Resource Locator (URL) information for downloading authentication information from the advertisement service information and displaying the URL information, wherein the URL information includes a URL;

when the update information includes the URL information and information about connection to the AP, accessing the URL through the AP;

when the update information includes the URL information and does not include information about connection to the AP, accessing the URL without using the AP; and

downloading the authentication information in response to accessing the URL;

update a stored authentication information for automatically connecting the electronic device and the AP, using the obtain authentication information, and

connecting the electronic device to the AP based on the update authentication information.

11. The method of claim 10, wherein the AP includes a first AP controller for providing advertisement service information and a second AP that is connected to the electronic device using the authentication information, and an information server comprises a first server and a second server,

receiving, by the AP the advertisement service information including the update information for authentication information and AP information for connection to the AP from an information server connected to the AP, and

providing, by the first server, the advertisement service information including the update information for authentication information and

providing, by the second server the AP information for connection to the AP.

12. The method of claim 10, further comprising:

sending a request for an advertisement service to the identified AP;

extracting URL information for downloading authentication information from advertisement service information received from the AP in response to the request for the advertisement service;
