Abstract

An Internet access method using a wireless communication module as a virtual Ethernet and a system thereof are provided to maintain an Internet connection state by providing a CDMA communication module, a WCDMA communication module or a GSM communication module to a generic Ethernet network environment. If the user of a user equipment attempts Internet access after connecting a portable terminal, where a wireless communication module is installed, through the NDIS network adapter of the user equipment, the NDIS network adapter recognizes the wireless communication module. At this moment, a controller in the user equipment carries out Internet environment setup using preset Internet access information(S304). If Internet environment setup is completed, a PPP(Point-to-Point Protocol) automatic authentication part in the user equipment attempts a PPP connection using PPP, and acquires necessary information for Internet access(S306). An Ethernet virtualization part in the user equipment executes virtualization processing for Ethernet protocol in order to inform an OS standard network layer that the wireless communication module, connected to the NDIS network adapter, is being normally operated(S308).

The present invention relates to an internet access method and system using a wireless communication module as a virtual Ethernet.

More specifically, the conventional CDMA communication module or GSM communication module is recognized as an Ethernet network adapter (Network Adapter) rather than a dial-up network method, so that wireless communication is possible in an environment such as a general Ethernet network connection. The present invention relates to an internet access method and system using a module as a virtual Ethernet.

In general, the Internet is a network of networks, and is currently composed of computer networks connecting the world. The Internet is able to transmit information between various networks having various technologies and devices by using a promised protocol, and is open and compatible, and subscribers are increasing exponentially. Various communication services are implemented or implemented based on the Internet, because the Internet has a foundation for transmitting various information.

Currently, the Internet access is mostly performed by using a computer connected to a computer communication network and by a PSTN subscriber connecting a computer network through a public telephone network using a portable computer and a modem. As it spreads, high-speed external network access through cable modems and asymmetric digital subscriber line (ADSL) modems has become commonplace after using dial-up modems in homes and small businesses.

In the conventional Internet access service through the ADSL modem, the ID of the subscriber through interworking with the authentication server by driving the access program at the subscriber's terminal by using a Point-to-Point Protocol (PP) through a dial-up networking method. Authenticate and allow access by assigning an IP address to the terminal used by the subscriber.

However, a dial-up networking method using a cable modem, a dial-up modem as well as a conventional ADSL modem requires a user to enter a phone number, ID, password, etc., by running a connection program on the user terminal. To them, the access process may seem complicated, and the access program has a problem that causes the terminal to fail.

On the other hand, in the Internet access service based on the Ethernet network, 802.1x protocol is added to the network device and port-based authentication of the device is performed. Such port-based authentication is an authentication that determines whether to allow access to the corresponding port regardless of IP assignment. In this way, the subscriber's terminal runs an access program to authenticate the subscriber's ID through interworking with the authentication server and allows access to the port to which the subscriber's terminal is connected.
