Description

Home networking method {METHOD FOR HOME NETWORKING}

The present invention relates to a home networking method, and more particularly, to a home networking method suitable for building a server at a low cost by securing a fixed domain name in a home network system implemented by assigning a floating IP address.

Recently, homes have been equipped with digitized home appliances. The term 'home appliance' includes electronic devices such as digital TVs, digital video cameras, digital stereo equipment, digital satellite services (DSS), and the like, and includes units having a function of exchanging data.

In addition, a remote control unit for developing a home network in which a user can control and command a plurality of home appliances using a single interface has been developed.

In a home appliance using a digital network interface, a control command is used to control between home appliances. The most typical control command is AV / C CTS (A / V Control) using a method of defining a hexadecimal code for each function of a home appliance. Command and Transaction Set).

The problem associated with using a remote control unit to command and control home appliances in this way in a home network system is that a particular remote control unit can only control and command home appliances that have control and command logic. to be.

Also, since the remote control unit does not recognize commands other than those provided at the time of product release, it does not have a control method for newly developed home appliances.

As a method for solving such a problem, methods for removing various space limitations and effectively displaying various information in controlling various home appliances by using a web server have been sought.

Web servers exist based on the Internet protocol, and each home appliance employing the web server must have an Internet Protocol address (IP address).

However, although a home browser based on a web browser can be assigned an IP address representatively, when a server is leased in a home by leasing a network dedicated line such as a network such as a general office, it is expensive in terms of cost.

Hereinafter, a conventional home networking method will be described with reference to the accompanying drawings.

1 is a block diagram schematically showing a conventional home network system.

As shown in FIG. 1, a conventional home network system is configured by connecting a digital TV, a digital video camera, a digital stereo equipment, a digital satellite service, and the like, and may be connected to an external network to utilize an Internet service.

Here, the digital TV, digital video camera, digital stereo equipment, digital satellite service, etc., have a web browser and operate as a client device 4.

In addition, a router (1) connected to an external network to convert addresses and protocols between networks, and a hub (3) for converging line cables of the client devices (4) in a network of a star topology It is configured by.

Such a home network system is generally assigned an IP address from a Dynamic Host Configuration Protocol (DHCP) server 2 using a communication network such as an asymmetric digital subscriber line (ADSL) or a cable modem. .

Here, the DHCP server 2 allocates information (subnet mask, gateway, DNS server address, etc.) of the IP address and network environment that an administrator must provide directly when constructing a network at the request of the client device 4. The IP address assigned to the client device 4 via 1) is a floating IP address that changes with connection time.

That is, since network information such as IP address and gateway changes frequently, it is difficult to give a fixed domain name.

Domain name is a term used to refer to a name and address of a host connected through a communication network in the Internet. In general, an English letter is used for convenience of a user.

However, in actual communication networks, IP addresses consisting of a combination of numbers are used instead of English names, so English domain names are numerically represented using a file or domain name server (DNS) with an address list for sites that users frequently access. IP address is converted.

However, the conventional home networking method as described above has the following problems.

In order to implement a home network system, if a communication network such as a DHCP-type ADSL or a cable modem is used, the IP address is changed every time the server is connected, so a fixed domain name cannot be used.

Therefore, it is impossible to implement a home network using Internet TV as a server in the home.

The present invention solves the problems of the conventional home networking method, and secures a fixed domain by periodically reconnecting to a private domain name service site using JavaScript in a home network system implemented by assigning a floating IP address. The purpose is to provide a suitable home networking method.

23: Hub 24: Private Domain Name Service Site

25: Internet TV 26: client device

A home networking method according to the present invention for achieving the above object comprises the steps of: assigning an IP address to a client for a server in a home networking method when a home network is accessed to an external network; Accessing a private domain name service site through a web browser and assigning a domain name to an IP address of the client for the server; Periodically reconnecting to the private domain name service site to maintain the domain name.

Hereinafter, a home networking method according to the present invention will be described with reference to the accompanying drawings.

2 is a block diagram schematically illustrating a home networking system according to the present invention.

As shown in FIG. 2, the home networking system according to the present invention operates as a client device 26 by connecting home appliances such as a digital video camera, a digital stereo facility, and a digital satellite service.

The router 21 is connected to the DHCP server 22 using a communication network such as an asymmetric digital subscriber line (ADSL) or a cable modem, and the hub 23 is connected to the client devices 26 in a star topology network. Concentrate the line cables.

In addition, an Internet TV 25 with a web browser is connected between the hub 23 and the client device 26 and used as a server of the client device 26.

3 is a flowchart illustrating a home networking method according to the present invention.

As shown in FIG. 3, power is first supplied to the Internet TV 25 (S31), and the DHCP server 22 is connected to use the Internet service (S32).

The Internet TV 25 receives an IP address and information (subnet mask, gateway, DNS server address, etc.) from the DHCP server 22 (S33).

At this time, the IP address assigned to the Internet TV 25 through the router 21 is a floating IP address that changes according to the access time.

Subsequently, the Internet TV 25 accesses a private domain name service site 24 which obtains a private domain name by identifying an IP address of a client connected through a web connection using a web browser (S34).

Here, the user can obtain an arbitrary private domain set by the user by accessing the private domain name service site 24, for example, a service site such as "http; // xdns.co.kr" and inputting a logon and a user password. (S35).

At this time, the private domain obtained through the private domain name service site is maintained regardless of the IP address of the Internet TV 25.

When the network disconnection of the DHCP server 22 occurs due to external network conditions, it is determined whether the period set by the user, for example, 30 minutes has elapsed (S37), and the Java engine is started (S36) to reconnect to the private domain name service site. (S34).

Here, the IP address of the Internet TV 25 allocated from the DHCP server 22 through reconnection is changed. In order to maintain the same domain, the Internet TV 25 may use Javascript (Hyper Text Markup Language) on the document. script) to create three frames (S38).

The first frame is HTML for automatically accessing a private domain name service site, and the second frame is configured by a user logging in to the private domain name service site in a pop-up window using JavaScript. HTML to automatically assign a domain name, and the third frame is HTML to periodically access a private domain name service site even when the network is disconnected.

Therefore, even if the network is disconnected outside the system or the IP address of the Internet TV 25 is changed, the same domain name can be automatically maintained.

In addition, such an Internet TV 25 can use a Unix (UNIX) as an operating system to configure a multi-system that a large number of users can connect to the network.

The home networking method according to the present invention as described above has the following effects.

First, it is possible to secure a fixed domain name in a home network system implemented by assigning a floating IP address.

Second, even if data traffic occurs outside the home network system, it is possible to continuously maintain a domain by automatically reconnecting.

Third, it is possible to build a server at low cost by using a DHCP-type communication network rather than a dedicated line.
