The present invention relates to a method and apparatus for dial-up networking connection, and to a method and apparatus for dial-up networking connection for serving IPv4 and IPv6 together.

Typically, communication systems are divided into wired communication systems and wireless communication systems. Representative examples of such wired communication systems include telephone communication, ISDN communication network, optical transmission communication, and internet communication. Wireless communication includes communication using a mobile telephone network, a wireless LAN system, and a wireless local loop (WLL) system. In the wireless communication system and wired communication systems, in line with the rapid development of the technology and the needs of users, wired communication technologies are combined with the wireless communication system, and both methods are commonly used.

Internet technology is generally developed to transmit and receive data by connecting to a predetermined server through a wired connection network. The existing Internet Protocol (IP), which is the basis of this Internet technology, was designed based on IP version 4 (hereinafter referred to as "IPv4") more than 20 years ago. However, in recent years, Internet users are growing very rapidly, and there are many problems in terms of lack of IP addresses and functionalities in order to accommodate IPv4 technology. Therefore, the mobile network using the mobile communication is currently evolving from Mobile IP version 4: (IPv4 below) to Mobile IP version 6: (IPv6 below).

On the other hand, Internet technology is based on wires as described above, and is used all over the world, and thus is composed of a huge number of Internet nodes and networks. In addition, most of these Internet nodes are currently designed and operated based on IPv4. Therefore, even if IPv6 technology, the next generation Internet system, is introduced and commercialized, it is expected that it will take a considerable time for the nodes that support IPv4 to be replaced with nodes that support IPv6. That is, there is a problem in that Internet nodes of IPv4 that are currently used cannot be replaced at once by an Internet node of IPv6, which is a next generation Internet system.

In addition, even if IPv6 technology is provided, access demand for the rich IPv4-based applications and services currently being served in the Internet (IP network) is expected to be quite large.

Therefore, when IPv6 is introduced into the network, most of the operators with the existing IPv4 network should consider a dual stack network that can accommodate both IPv4 and IPv6. Here, dual stack technology is a technology that simultaneously handles IPv4 and IPv6 protocols in one system (host or router), that is, to maintain the compatibility of existing PCs and terminals using IPv4, and also for continuity of applications. Dual stack network supporting both IPv6 and IPv6 should be designed and operated. In addition, in order to access both the IPv4 network and the IPv6 network, the terminal must provide a dual stack function supporting both IPv4 and IPv6.

However, even if the terminal supports dual stack, it must select the connection to either IPv4 or IPv6 network, so the other contents or network services cannot be used while the terminal is connected. In other words, when connected via IPv4, the IPv6 application or network cannot be used or vice versa.

Accordingly, the present invention has been made to solve the above problems, and provides a dial-up networking access method and apparatus that can simultaneously provide IPv4 and IPv6 services by providing an IPv4 address and an IPv6 address to a terminal through a telephone network.
