Description

System and method for maintaining a mobile internet connection

The present invention relates to a system and method for maintaining a wireless Internet connection, and more particularly, to a system and method for maintaining a wireless Internet connection for consistently maintaining a user's Internet connection in a wireless Internet environment.

In general, the Internet is a globally connected network for exchanging information. In order to access information provided by the Internet, a user must run a client program called a web browser. In order to search information on the web, you need a program that retrieves the information provided by the web server on your computer and displays it on the screen in text or graphics. Such a program is called a web browser. Of course, it is a multimedia search program that supports images, sound files, and videos.

These web browsers connect users to the Internet. Various web servers are connected to the Internet, and web browsers send specific commands to connect to specific web servers. A web server is a computer program that delivers information to clients such as web browsers connected to the Internet.

Once connected to the Internet, the user can browse various web sites. Web sites maintain web pages in the form of text and pictures that contain information about a particular topic or company. These web pages are primarily made of Hyper Text Markup Language (HTML), each with its own Internet address and route (Unified Resource Locator).

The user can retrieve information from the Internet by entering such a URL into a web browser. Web pages have text or pictures and linking information (link information) to other web pages, so that specific web pages can be requested. In addition, the web page may be provided in the form of a schedule in which a user may input information.

When a user inputs information to such a web page and transmits the information to a web server, the web server may provide different information to the user according to the information input by the user.

The web browser may be installed and executed on a computer directly connected to the Internet, but may also be connected through a wired / wireless telephone network on a mobile device such as a mobile phone or a personal mobile terminal device.

In order to find the desired information by accessing the Internet through a wired / wireless telephone network, the user first makes a phone call, connects to the Internet, requests a desired web page, receives it from a mobile device, and then enters the desired information into the web page to search for information. However, when the time required for inputting the desired information into the web page is very large, this process has a disadvantage in that a large communication cost is required in the portable device.

The current Hypertext Transfer Protocol (HTTP) standard is a method in which a connection is disconnected shortly after a user accesses a particular URL. As a result, every time a homepage or other URL is accessed, new connections and disconnects are repeated, resulting in overhead. However, unlike the wired Internet, the wireless Internet environment has a relatively low speed and a long delay time, which greatly affects communication performance due to a large overhead due to connection and disconnection. Although the recent specification of HTTP (HTTP 1.1) supports Keep-Alive HTTP connections, this is optional and difficult to use as a consistent connection maintenance method.

In addition, conventionally, when a user connects to the Internet, he is simply ready to connect, and thus cannot continue using a service previously used. Currently, although there is a history function of the browser, there is a problem that the function is very limited such as remembering only a URL.

SUMMARY OF THE INVENTION The present invention has been made in an effort to solve such a conventional problem, and an object of the present invention is to provide a method for maintaining an Internet connection for consistently maintaining a user's Internet connection in a wireless Internet environment.

Another object of the present invention is to provide a system for performing the above method of maintaining the Internet connection.
