6 is a functional block diagram of an embodiment of a remote Internet access device for explaining the Internet access method according to the present invention.

Referring to the drawings, the Internet connection method using the remote Internet access device of the present invention will be described.

First, a user who wants to access a remote Internet access device of the present invention selects an Internet access service menu after connecting a modem to a telephone network matching device. Thus, a packet for initial PPP access of a user is serialized inside a system for message communication in an HDLC frame structure. It is received by the HDLC drive 608 of the functional components of the main processor board using the communication bus. Afterwards, the packet for user authentication passes through the Link Layer Driver (LLD) 606 and the Link Control Protocol (LCP) 603, and the Password Authentication Protocol (PAP) 601 of the Internet Protocol Control Protocol (IPCP) 604. When the PAP / IPAM 601 exchange is completed and the PAP / IPAM 601 exchange is completed, the Internet access function starts. Here, the PAP / IPAM 601 provides a function of determining whether the PPP user can access the Internet.

Then, when the PPP user accesses the system and negotiates the IPCP 604, an IP address is requested as a negotiation option. In this case, the IPCP 604 performs an IP address assignment.

When the PPP procedure is normally completed between the user and the Internet access device, the Internet access function is completed and an IP address is allocated. After that, when the normal Internet service is provided, the user's IP packet is received by the HDLC driver 608 and the LLD 606 is provided. And over the IP 602 layer to the Internet via Ethernet driver 607.

Packets received on the Internet are sent to the user's personal computer in the reverse flow of the process.

The IP packet of the Internet service user through the PPP access procedure is encapsulated in the information field of the PPP data link layer frame and sent on the link.

In addition, the Link Control Protocol (LCP) 603 performs the function of automatically negotiating the PPP summary format options with the other party to provide flexibility to adapt to a greatly changing communication environment.

The role of each component of the remote Internet access device will be described in more detail as follows.

The Password Authentication Protocol (PAP) 601 provides a function of determining and processing the Internet accessibility of the PPP user in the state where the protocol exchange of the Internet Protocol Control Protocol (IPCP) 604 is completed.

If an account and password are transmitted from the user using the PAP 601, the system determines whether the account is allowed and grants a service access right. Here, the function is made for future use, and the current remote Internet access device is to pass all users without access control. In addition, the Internet Protocol Address Manager (IPAM) 601 requests an IP address as a negotiation option when a PPP user accesses a system and negotiates an IPCP 604. In this case, an IP address is assigned.

Logically, the maximum number of IP addresses that can be assigned in IPAM 601 is 253. Internet Protocol Control Protocol (IPCP) 604 is one of the NetWare Core Protocols (NCPs) available in a PPP environment and provides the ability to configure, operate, and halt an IP module at both ends of a point-to-point link.

IPCP 604 uses the same packet switching scheme as LCP 603 and is exchanged when PPP reaches the network layer protocol stage. When the configuration of the selected network layer protocol is completed in this way, the IP packet is encapsulated in the information field of the PPP data link layer frame and sent on the link. In addition, the Link Control Protocol (LCP) 603 performs the function of automatically negotiating PPP encapsulation format options with the other party to provide flexibility to adapt to a greatly changing communication environment.

To establish communication on a point-to-point link, each end of the PPP link must exchange LCP 603 packets to establish and test the data link. Once the exchange is complete, PPP arrives at the network protocol state, where NCP packets are exchanged to select and configure one or more network protocols.

The link layer driver (LLD) 606 transmits PPP frames generated from the IP 602, the LCP 603, and the IPCP 604, and transmits the PPP frames received from the HDLC driver 608 to the IP 602, LCP. 603, provides a function for forwarding to IPCP 604. In addition, while managing the state of the PPP ports, it controls the transmission of PPP frames according to the transmission and reception command and release command of the ports.

Inside the LLD 606, frame data similar to HDLC is configured as a PPP frame or vice versa.

On the other hand, the present invention has the following functions in order to provide an open Internet access service and billing collection function service using the PPP protocol.

When using a telephone number, a PSTN subscriber is provided with an Internet service using PPP (RFC 1990), and can use various additional services such as a virtual private network providing function and a satellite internet service providing function. In this case, the remote Internet access apparatus provides the functions of a link layer of the PPP (RFC 1661) and a network layer of the PPP to provide the PPP function.

It also aims to make the Internet accessible to PSTN subscribers at a fast pace, providing a method independent of the network and software architectures of users and information providers currently available on the Internet. In addition, the subscriber can easily access and use the service anytime and anywhere with a given telephone number and modem regardless of the internal structure and environment.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

As described above, the present invention can provide the Internet access service in a single device structure to connect to a host of information providers, thereby improving the reliability and stability of the system, using a high-speed device internal bus, As processing becomes possible, it is effective to improve service speed and perform stable performance when providing a service.
