Abstract

PURPOSE: A method for constructing an automatic home network by using an IPv6(Internet Protocol version 6) system and a telephone number is provided to inflexibly or flexibly map an information appliance name with final 4 bits of an address by adopting a similar domain name type, thereby reducing the number of inquiring times of a DNS(Domain Name Server). CONSTITUTION: When a combined address request is received from an information appliance, a home gateway assigns one of combined 124-bit unicast addresses to the information appliance(S400,S401). The information appliance randomly assigns the rest bits, and generates a unique home network address(S402). Whether the generated address is the inherent address is decided(S403). If so, the generated address and a domain name are reported to the home gateway(S404). The home gateway reports the address of the information appliance and the domain name to an upper DNS(S405).

Description

Method for Building Auto Home Network Using Telephone Number and IPv6 using Next Generation Internet Address Resource System and Phone Number

The present invention relates to a method for constructing an automatic home network using a next-generation Internet address resource system and a telephone number. In particular, the present invention relates to a next-generation Internet address resource system (Internet protocol version 6, IPv6) and an E.164 format telephone number automatically. It relates to a method for building a home network and assigning IPv6 addresses to information appliances.

In the past, home networking was limited to network technology that integrates wired and wireless, but in the future, it can be integrated with information appliances to control and use various kinds of information appliances anywhere.

In order to play this role, information appliances require an IP address (home network address). The number of terminals of information appliances has increased in earnest since 2005, and by 2010, more than 20-30% of existing appliances have internet access. It is likely to contain the last name, making it difficult for the current Internet Address Resource System (IPv4) address.

That is, IPv4 using 32-bit addressing system can logically provide about 4.2 billion address spaces, but the number of addresses actually available by class allocation is smaller.

Therefore, when building a home network, if the network is configured using a private IP address range due to lack of IPv4 address, this address does not have internet connection. It uses a proxy server, dynamic host configuration protocol (DHCP), and network address translation (NAT) to connect to the Internet, but does not solve the underlying problem of address space shortage.

In other words, the proxy server is a server that acts as an intermediary between the user and the Internet, and delivers only the data of the application layer. Although the proxy server provides a function of internet connection even when using a private IP, it increases the complexity of the network configuration and causes a bottleneck. Can be.

DHCP uses the concept of "lease", which allows a given IP address to be valid for that computer for only a certain amount of time, and the lease time may vary depending on how long the user will need to access the Internet at a particular location. Therefore, because it depends entirely on the server that assigns the IP address, if the server goes down, it cannot receive the IP address, so all hosts on the private network cannot use the Internet.

NAT is an IP address translation in an internal network using a different IP address than that known from the external network. The general agreement is described in RFC 1631, which has many advantages over the above two methods. There is a disadvantage that cannot be avoided and can only be used on a small scale.

Accordingly, the problem of address space shortage caused by the activation of the Internet can be solved by the next-generation address resource system (IPv6) method having a 128-bit address system. The IPv6 address is a subnet prefix and an interface ID as shown in FIG. Use Subnet prefix is the information allocated from the external network by the network management regulation. The interface ID is automatically created using the identifier information on the network interface card. The automatic address generation method is defined in the Internet standard RFC 2373 standard. . Also, when building a home network in IPv6, unlike IPv4, there is no address shortage problem, so IP can be allocated without establishing a proxy server, DHCP, NAT, or the like.

However, when using the general IPv6 unicast as shown in FIG. 1, the user needs to be assigned a necessary address through a carrier, and the carrier needs a separate task to provide it. If you use DHCPv6, you need to install a DHCPv6 server, and if you need to access information appliances from outside the Internet, you need a separate DNS server.

In addition, since the initial number of users in the home network was small, the cost burden of installing a separate DHCPv6 server and a DNS server for the home network was very large.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and has an object of automatically configuring a home network using a telephone number and IPv6, and allocating an IPv6 address to information appliances.

It also adopts a domain name format similar to the .E.164.arpa domain name structure using telephone numbers as defined in the Internet standard RFC 2916, which allows fixed or fluid mapping of information appliance names to the last 4 bits of the address. The purpose of this study is to reduce the number of domain name server (DNS) lookups, and to provide a way for the created domain name to be accessed and manipulated by a web browser.
